Ecological Informatics
Wikipedia: Ecological Informatics Ecoinformatics, or ecological informatics, is the science of information (Informatics) in Ecology and Environmental science. It integrates environmental and information sciences to define entities and natural processes with language common to both humans and computers. However, this is a rapidly developing area in ecology and there are alternative perspectives on what constitutes ecoinformatics. A few definitions have been circulating, mostly centered on the creation of tools to access and analyze natural system data. However, the scope and aims of ecoinformatics are certainly broader than the development of metadata standards to be used in documenting datasets. Ecoinformatics aims to facilitate environmental research and management by developing ways to access, integrate databases of environmental information, and develop new algorithms enabling different environmental datasets to be combined to test ecological hypotheses. Ecoinformatics characterize the semantics of natural system knowledge. For this reason, much of today's ecoinformatics research relates to the branch of computer science known as Knowledge representation, and active ecoinformatics projects are developing links to activities such as the Semantic Web. Current initiatives to effectively manage, share, and reuse ecological data are indicative of the increasing importance of fields like Ecoinformatics to develop the foundations for effectively managing ecological information. Examples of these initiatives are National Science Foundation Datanet projects, DataONE and Data Conservancy.

Impacts of coal mining on heavy metal concentration and microbial community composition in surrounding soils.
Journal of environmental sciences (China), 162:465-475.
Coal mining activities have been demonstrated to result in substantial environmental contamination, posing severe risks to surrounding soil ecosystems. However, the interaction between microbial community structure and environmental factors in coal mining areas remains poorly understood. In this study, we evaluated the health status of soils and the effects of heavy metals on microbial community structure in coal mining areas through comprehensive soil health assessments and sequencing. Our findings revealed that soils impacted by mining activities exhibited low soil health index values, with health grades ranging from moderate to poor. Active biomarkers including Gemmatimonadota (phylum), Patescibacteria (phylum), and Saccharimonadia were highly enriched in mine soils, with some developing metal tolerance. Additionally, potential pathogenic bacteria, including MND1, Bacillus, and Pannonibacter, and potential pathogenic fungi including Fusarium and Alternaria, showed significantly higher abundance in these soils. Heavy metal concentrations, particularly Cu and As, were strongly correlated with the distribution of certain bacterial genera, alongside variations in soil physicochemical properties, including C/N ratios and organic matter content. These findings demonstrate complex relationships among heavy metal pollution, soil properties, and microbial communities, underlining the potential risks posed by mining activities to soil health and agricultural productivity in affected regions.

Transforming mine dump waste soil into biogeo-composites with vegetation growth regulation function through bio-mediated treatment.
Journal of hazardous materials, 506:141630 pii:S0304-3894(26)00608-4 [Epub ahead of print].
Valorization of mine waste soils into sustainable materials provides both ecological protection and recycling benefits. This study develops a calcium lignosulfonate (CLS)-enzyme-induced calcium carbonate precipitation (EICP)-driven biogeo-composite that simultaneously enhances mechanical stability, regulates hydraulic behavior, and promotes vegetation growth. Laboratory tests demonstrated that CLS-EICP treatment increased shear strength of soils through cohesion enhancement driven by rigid CaCO3 bonding and ductile CLS bridging. Hydraulic conductivity reduced by two orders of magnitude and slaking resistance significantly enhanced. Microstructural analyses confirmed a dense organic-inorganic hybrid network formation, enabling a transition from surface to volumetric cementation and promoting structural densification. Field trials further validated these findings, as biogeo-composite-treated slopes resisted gully erosion, delayed pore water pressure build-up, and maintained overall stability while supporting uniform vegetation growth. These results highlight the dual role of CLS-EICP composites in slope reinforcement and eco-functional regulation, offering a scalable pathway for the valorization of waste soils.

Ecosystem structure influences human health outcomes as the basis for green prescriptions.
Scientific reports pii:10.1038/s41598-026-40752-8 [Epub ahead of print].
The role of Nature [**][**] in supporting human life, health, and well-being has been recognized and appreciated since ancient times, and has become a topic of scientific investigation with early studies dating back several decades. In recent years, this field has gained renewed attention and methodological refinement, driven by interdisciplinary frameworks and advances in environmental psychology, ecology, and health sciences, including new ecosystem-based approaches that highlight the deep human dependence on Nature for both mental and physical health. Among Nature-based Interventions that aim at exposing people to the natural environment, Green Prescriptions (GRx) represent a promising strategy to address human health challenges in ways that can also support environmental sustainability, in line with the Planetary Health framework. However, significant gaps remain in our understanding of the specific ecological factors that influence health outcomes during therapeutic activities in natural settings; in particular, it remains unclear how ecosystem structure and functions modulate health responses in individuals. This nine-month pilot study examined the therapeutic efficacy of GRx within a Mediterranean woodland ecosystem, to assess if and how variations in ecosystem structure influence health outcomes in individuals with complex chronic conditions. Using a novel aggregated index to characterize four distinct woodland patches, we identified a gradient in structural complexity where greater ecosystem functionality was consistently associated with greater alleviation of psychological and physical symptoms. Notably, health outcomes were independent of weather conditions and participants' baseline connectedness to Nature, whereas temporal dynamics and the presence of peaks in the productivity of some species influenced both perceptions and physical responses. This underscores the intrinsic role of ecosystem properties and dynamic functions in modulating human health responses, while also suggesting the potential presence of a complex set of signals pervading complex ecosystems that is worth further exploration. The results demonstrated cumulative health benefits, including significant reductions in medication use over time, particularly among individuals with respiratory challenges and chronic pain. Furthermore, participants showed improved environmental awareness and behavior, embracing the interconnectedness principle, which is integral to effective environmental conservation. This study highlights the potential of well-functioning ecosystems to serve as co-effectors in healthcare interventions, advancing the goals of Planetary Health while reinforcing the importance of preserving ecological integrity. (**In this paper, "Nature" is written with a capital "N" to indicate the living biosphere and the abiotic matrices (soil, air, and water) in which life is embedded, including the ecological processes they sustain. This capitalization reflects the scientific perspective of Nature not merely as a passive backdrop, but as an active ecological system that interacts and influences human health.

A global Quasi-SMILES model based on the Monte Carlo algorithm for assessing the multi-organism aquatic ecotoxicity of personal care products.
Ecotoxicology and environmental safety, 312:119948 pii:S0147-6513(26)00277-0 [Epub ahead of print].
Personal care products (PCPs) are widely used for external applications on the body, and their increased consumption has raised concerns about their potential environmental impact, particularly in aquatic ecosystems. Evaluating the aquatic ecotoxicity of PCPs is essential, but the process is a long and difficult task. Thus, it is crucial to employ tools for rapid screening. The quantitative structure-activity relationship (QSAR) approach can leverage existing data to identify potentially hazardous PCPs quickly. This study uses QSAR models to assess the aquatic ecotoxicity of 159 PCPs across three organisms' algae, crustaceans, and fish providing a broader ecological perspective than traditional methods, which typically focus on a single organism. A QSAR model was implemented using CORAL software, which utilizes the SMILES format to predict aquatic toxicity. However, traditional SMILES do not incorporate experimental context, limiting prediction accuracy. To address this, the Quasi-SMILES method extends the traditional SMILES notation by incorporating experimental conditions related to three key organisms of the aquatic trophic level algae (Pseudokirchneriella subcapitata), crustacean (Daphnia magna), and fish (Pimephales promelas) thus enabling more accurate predictions of chemical behavior under diverse environmental conditions. Using random data splitting and multiple objective functions, 40 models were developed based on the Monte Carlo method. The model that combined the Ideal Correlation Index (IIC) and the Correlation Intensity Index (CII) as dual objective functions achieved the best predictive performance for split 4, with rm[2] = 0.7396, R[2]= 0.7757, and Q[2] = 0.7509 for validation set highlighting the effectiveness of multi-objective optimization strategies.

Preliminary evidence of extrarenal sodium storage in a large mammal: implications for comparative physiology and hypertension research : Running: Sodium storage in cattle.
Pflugers Archiv : European journal of physiology, 478(3):.
Under conditions of dietary sodium (Na[+]) excess, the kidneys may fail to adequately excrete Na[+], potentially compromising blood pressure homeostasis. Body tissues, such as skin, can offer sites of short-term extrarenal Na[+] storage and previous research has shown that this can help guard against hypertension in small mammals (e.g., rodents). Large mammals have relatively greater Na[+] storage potential, but whether extrarenal Na[+] storage occurs for this group is unknown. Here, we report preliminary evidence of extrarenal Na[+] storage in cattle. We provided a large pulse-dose of NaCl to four cattle (body mass: ~720 kg) and measured excretion of Na[+] and potassium (K[+]) in urine and faeces for a period of 7-days. Following NaCl administration, Na[+] excretion spiked in both urine and faeces for ~ 48 h before returning to baseline measurements. After ~ 96 h, however, Na[+] excretion increased again; a consistent physiological phenomenon across all individuals studied. We did not observe a pattern in urinary K[+] excretion, indicating that the mechanism of Na[+] storage does not appear to involve exchange for K[+]. However, faecal K[+] excretion was reciprocal to that of Na[+], presumably reflecting exchange of Na[+]/K[+] across the walls of the large intestine. We infer that during the initial period of Na[+] stress, short-term extrarenal Na[+] storage occurred and the stored Na[+] was later released only when the body had returned to Na[+] homeostasis. Additional experiments are required to understand how patterns of Na[+] regulation changes across body sizes and the specific body compartments involved. Cattle may be a useful model system for examining the impact of high Na[+] intake in mammals larger than humans.

Barriers to Designing Inclusive Ecological Momentary Assessment and Wearable Data Collection Protocols for AI-Driven Substance Use Monitoring in Hawai'i.
Pacific Symposium on Biocomputing. Pacific Symposium on Biocomputing, 31:566-579.
Ecological momentary assessment (EMA) and wearable sensors offer unprecedented opportunities to capture the dynamics of substance use through real-time, high-resolution behavioral and physiological data. These data streams are increasingly used to train AI/ML models for digital phenotyping and predictive intervention, raising critical questions about fairness, bias, and inclusivity in model development. However, the adoption of these technologies, or the lack thereof, among diverse and historically marginalized groups raises questions and challenges of equity, cultural relevance, and participant trust. In this study, we conducted a four-week observational study with adults in Hawai.i where we combined continuous Fitbit monitoring and daily EMA surveys to document substance use patterns and cravings. Through semi-structured interviews and grounded theory analysis, we identified six primary barriers to study participation and adherence: (1) disruptions to daily routines, (2) physical and psychosocial discomfort associated with wearing the Fitbit device, (3) concerns about aesthetic compatibility and professional appearance, (4) phonerelated issues, (5) challenges related to substance use and cravings, and (6) socially sensitive contexts. We also highlight participant-identified facilitators, such as the value of participant-driven scheduling, motivational feedback, and contextually adaptive protocols. Drawing on these collective findings, we propose a set of design guidelines aimed at advancing the inclusivity, engagement, and fairness of wearable-based EMA research.

Investigating Mining-Induced Surface Subsidence in Mountainous Areas Using Integrated InSAR and GNSS Monitoring.
Sensors (Basel, Switzerland), 26(4):.
Leveraging the complementary advantages of InSAR and GNSS, this study proposes a refined method for monitoring mining-induced surface subsidence by integrating both technologies. The method begins with calculating the time-series cumulative subsidence basin from InSAR. Subsequently, a constraint condition is established to identify large-gradient deformations, thereby distinguishing the subsidence edge from the subsidence center. For the subsidence edge with minor deformation, the InSAR results are retained. For the large-gradient subsidence center, the subsidence basin around the mining panel is reconstructed by integrating InSAR and GNSS models. Continuous surface deformation information in a geographic coordinate system is then obtained through spatial interpolation, ultimately yielding comprehensive surface subsidence results across the mining area. Taking a mining area in Shanxi Province as the study region, the feasibility and accuracy of the proposed method were validated using 35 SAR images acquired between April 2016 and September 2017, along with leveling measurement data from the mining panel. The maximum surface subsidence rate of the settlement basin obtained from the solution is -186.68 mm/year, and the maximum surface subsidence amount is 248 mm. Compared with the InSAR monitoring results, the root mean square error of the data collaborative monitoring is reduced by 96.8%, and it is reduced by 64.4% compared with the GNSS probability integral method. The results demonstrate that the proposed method can achieve subsidence results consistent with the actual situation. Its monitoring capability is significantly superior to that of using either InSAR or GNSS alone, effectively compensating for the limitations inherent in each individual technology when applied to mining subsidence monitoring. Consequently, this integrated approach provides more accurate and reliable information on surface subsidence in mining areas.

Assessment of Salivary Parameters-pH, Buffering Capacity and Flow-Associated with Caries Susceptibility.
Diagnostics (Basel, Switzerland), 16(4):.
Background/Objectives: Saliva plays an essential role in maintaining the oral ecological balance, and its quantitative and qualitative characteristics may influence susceptibility to dental caries. The aim of this study was to determine susceptibility to dental caries based on the DMFT index and to establish a correlation between caries experience and salivary parameters in a group of young adults. Methods: This cross-sectional study was conducted between July and November 2025 on a sample of 87 fourth-year students from the Faculty of Dentistry in Craiova. Each participant underwent an intraoral clinical examination to determine the DMFT index. The salivary parameters assessed included unstimulated salivary flow rate, saliva consistency, salivary pH, stimulated salivary flow rate, and buffering capacity, using the GC Saliva-Check Buffer kit. Statistical analyses were performed using SPSS (Statistical Package for Social Sciences) software, version 26 (SPSS Inc., Armonk, NY, USA). Results: The mean DMFT index value for the entire sample was 8.26 ± 4.481, with higher values observed among female participants. Low salivary pH was significantly associated with higher DMFT values. Participants with low or very low buffering capacity exhibited higher DMFT values compared to those with normal capacity, indicating that a reduced ability to neutralize salivary acidity is associated with increased caries activity. Conclusions: The results indicate that salivary pH and buffering capacity are important factors in dental caries susceptibility among young adults. The integration of salivary testing into the diagnostic assessment of caries risk may contribute to personalized and effective preventive strategies.

The aim of this study was to determine susceptibility to dental caries based on the DMFT index and to establish a correlation between caries experience and salivary parameters in a group of young adults. Methods: This cross-sectional study was conducted between July and November 2025 on a sample of 87 fourth-year students from the Faculty of Dentistry in Craiova. Each participant underwent an intraoral clinical examination to determine the DMFT index. The salivary parameters assessed included unstimulated salivary flow rate, saliva consistency, salivary pH, stimulated salivary flow rate, and buffering capacity, using the GC Saliva-Check Buffer kit. Statistical analyses were performed using SPSS (Statistical Package for Social Sciences) software, version 26 (SPSS Inc., Armonk, NY, USA). Results: The mean DMFT index value for the entire sample was 8.26 ± 4.481, with higher values observed among female participants. Low salivary pH was significantly associated with higher DMFT values. Participants with low or very low buffering capacity exhibited higher DMFT values compared to those with normal capacity, indicating that a reduced ability to neutralize salivary acidity is associated with increased caries activity. Conclusions: The results indicate that salivary pH and buffering capacity are important factors in dental caries susceptibility among young adults. The integration of salivary testing into the diagnostic assessment of caries risk may contribute to personalized and effective preventive strategies.},

Smart Devices and Multimodal Systems for Mental Health Monitoring: From Theory to Application.
Bioengineering (Basel, Switzerland), 13(2):.
Smart devices and multimodal biosignal systems, including electroencephalography (EEG/MEG), ECG-derived heart rate variability (HRV), and electromyography (EMG), increasingly supported by artificial intelligence (AI), are being explored to improve the assessment and longitudinal monitoring of mental health conditions. Despite rapid growth, the available evidence remains heterogeneous, and clinical translation is limited by variability in acquisition protocols, analytical pipelines, and validation quality. This systematic review synthesizes current applications, signal-processing approaches, and methodological limitations of biosignal-based smart systems for mental health monitoring. Methods: A PRISMA 2020-guided systematic review was conducted across PubMed/MEDLINE, Scopus, the Web of Science Core Collection, IEEE Xplore, and the ACM Digital Library for studies published between 2013 and 2026. Eligible records reported human applications of wearable/smart devices or multimodal biosignals (e.g., EEG/MEG, ECG/HRV, EMG, EDA/GSR, and sleep/activity) for the detection, monitoring, or management of mental health outcomes. The reviewed literature after predefined inclusion/exclusion criteria clustered into six themes: depression detection and monitoring (37%), stress/anxiety management (18%), post-traumatic stress disorder (PTSD)/trauma (5%), technological innovations for monitoring (25%), brain-state-dependent stimulation/interventions (3%), and socioeconomic context (7%). Across modalities, common analytical pipelines included artifact suppression, feature extraction (time/frequency/nonlinear indices such as entropy and complexity), and machine learning/deep learning models (e.g., SVM, random forests, CNNs, and transformers) for classification or prediction. However, 67% of studies involved sample sizes below 100 participants, limited ecological validity, and lacked external validation; heterogeneity in protocols and outcomes constrained comparability. Conclusions: Overall, multimodal systems demonstrate strong potential to augment conventional mental health assessment, particularly via wearable cardiac metrics and passive sensing approaches, but current evidence is dominated by proof-of-concept studies. Future work should prioritize standardized reporting, rigorous validation in diverse real-world cohorts, transparent model evaluations, and ethics-by-design principles (privacy, fairness, and clinical governance) to support translation into practice.

Remote cognitive training for older adults using tablets: A pilot trial.
Digital health, 12:20552076261417771.
BACKGROUND: Cognitive decline significantly affects the functional and intrinsic capacities of older adults, highlighting the need for effective interventions. Evidence suggests that mentally stimulating activities, particularly those supported by digital technologies, can promote cognitive health and quality of life in aging populations.
OBJECTIVE: This pilot trial examined the feasibility and preliminary effectiveness of GameAAL, a multidomain Cognitive Training programme delivered via tablet and television, in older adults with cognitive impairment or dementia.
METHODS: The intervention targeted key cognitive domains including attention, reaction time, memory, language, and executive functioning. Forty-one older adults (aged 60-93), living in nursing homes, participated in a 6-month programme. The tablet intervention group (n = 10) completed 30 sessions using a tablet device, while the TV intervention group (n = 31) completed nine sessions using a TV interface. All participants engaged with six serious games designed around cognitive tasks related to activities of daily living.
RESULTS: Pre- and post-intervention assessments included the Montreal Cognitive Assessment (MoCA) and the Hospital Anxiety and Depression Scale (HADS). The Tablet group showed a trend towards improved MoCA scores following the intervention, whereas the TV group did not show significant changes. At the post-intervention, the Tablet group demonstrated significantly better cognitive performance compared to the TV group (p = 0.044). No significant between-group differences were observed in HADS scores.
CONCLUSION: The findings suggest that the GameAAL Cognitive Training programme may help improve cognitive function in older adults with cognitive impairment by combining computer-based exercises with ecologically valid tasks.

Early Improvement Predicts Treatment Response in Depression: An Ecological Momentary Assessment Study in an Inpatient and Day Clinic Setting.
Behavior therapy, 57(2):234-249.
Predicting treatment response through early improvement can reduce patients' time in ineffective treatments before considering alternatives. However, for psychological interventions, there is no consensus on what time window and improvement rate early in the treatment is the most informative for distinguishing treatment responders from nonresponders. This study investigated these aspects in an inpatient and day clinic setting among severe depressed patients who perceived intensive psychological treatment and compared Weekly Questionnaire Assessments (WQA) and Ecological Momentary Assessment (EMA) regarding their power to predict treatment response through early improvement. Fifty-two depressed patients were randomly assigned to one of three intensive 7-week psychological interventions (two individual and two group sessions per week) applied in an inpatient or day clinic setting. Early improvement was assessed three times daily using EMA and weekly using questionnaires (BDI-II). Linear Regression Models and Receiver Operating Characteristic Analyses were conducted to predict treatment response (BDI-II improvement from pre- to postintervention ≥50%) in patients who received a full course of treatment. Moreover, ratios of true negative/false negative predictions were calculated to explore the predictive value of different early improvement definitions: 10%, 20%, 30%, or 40% improvement after 1, 2, 3, or 4 treatment weeks. Both EMA and WQA significantly predicted treatment response after 3 weeks with AUC values of 73% (EMA) and 77% (WQA). A WQA-assessed 10% improvement after 4 weeks yielded the highest ratio of true negative/false negative predictions, with a true negative rate of 22% and a false negative rate of 0%. 10% improvement in depressive symptoms assessed with WQA after 3 to 4 weeks of treatment was the best predictor in our study. Further research is needed to validate the results. This trial design is registered with osf.io/9fuhn.

The Third Study of Infectious Intestinal Disease (IID3 Study) in the Community: Protocol for UK-Based Prospective Cohort Studies Investigating the Disease Burden.
JMIR research protocols, 15:e88759 pii:v15i1e88759.
BACKGROUND: There is a significant hidden burden of infectious intestinal disease (IID) in the UK community, which has increased over time. In the late 2000s, the Second Study of Infectious Intestinal Disease (IID2 study) estimated 17 million IID cases annually in the United Kingdom. However, only a small proportion of cases present to health care, and even those are often not tested for causative organisms.
OBJECTIVE: The Third Study of Infectious Intestinal Disease (IID3 study) aims to determine the IID burden in the UK community, estimate the underreporting level in routine practice and the general population, and recalibrate UK national surveillance based on the new incidence rates.
METHODS: We will follow methods of previous studies, along with modern pathogen detection methods and digital platforms for recruitment and follow-up. Participants will be recruited to three population-based prospective cohorts: cohort 1 (the general population), cohort 2 (patients with IID presenting to general practices [GPs]), and cohort 3 (enumeration study of IID cases presenting to GPs). Microbiological analysis of stool samples in cohorts 1 and 2 will include testing for a wide range of causative organisms using molecular assays, including pathogen targets not routinely sought by National Health Service (NHS) laboratories. Additional characterization of pathogens will be conducted at national reference laboratories. The incidence rates of IID and organisms detected in cohorts 1-3 will be compared to national surveillance systems, both laboratory and syndromic. Descriptive statistics and analysis will allow comparison of IID rates within each cohort, estimate the overall burden of disease caused by different pathogens, and compare findings to earlier IID studies.
RESULTS: A favorable ethical opinion was obtained from the UK Health Research Authority on August 4, 2022. A pilot phase to test the sampling process was conducted from January to August 2023. Participant recruitment commenced on September 1, 2023, for cohort 2 and on March 16, 2024, for cohort 1; recruitment ceased on August 31, 2025. Data collection is complete, and data analysis is to begin. The study is expected to end in September 2026.
CONCLUSIONS: Since the first and second IID studies, changes have occurred within national surveillance systems, the NHS structure, and public recommendations about when to consult a GP and where to seek health care advice, which may have altered the extent of IID reporting and the perceived burden in the community, creating greater uncertainty about the representativeness of IID rates. The IID3 study results will provide insight into trends in disease incidence over time and help quantify inequalities in IID in the UK community. Revised estimates can inform policy related to prevention, including food standards and disease management. Furthermore, advances in molecular diagnostics will significantly enhance pathogen detection, increasing our understanding of the causes of IID.

Geometrical preference of anchoring sites in the unicellular organism Stentor coeruleus.
Proceedings of the National Academy of Sciences of the United States of America, 123(9):e2518816123.
Organisms often inhabit environments comprising complex structures across various scales. Animals rely on visual information from surrounding geometrical structures for navigation. Even at the microscale, various microsediments form complex structures in microbial habitats. The movement of microorganisms is passively affected by collisions and hydrodynamic interactions with surrounding structures. However, the influence of microenvironmental geometry on behavioral changes of unicellular organisms that lack visual perception remains unclear. Here, we developed geometrically structured chambers to investigate anchoring site preferences in the swimming ciliate Stentor coeruleus. Our experiments revealed that S. coeruleus preferentially anchored in narrow regions characterized by specific geometrical features, including corner angle, depth, and curvature at the corner end. Before anchoring, free-swimming S. coeruleus changed its behavior to move along the boundary wall of the chambers, accompanied by Ca[2+]-induced asymmetrical body deformation. To further investigate how S. coeruleus moves along the wall continuously, we conducted a hydrodynamic simulation and revealed that the asymmetric morphology causes asymmetric propulsive forces, explaining wall-following behavior through physical interactions with a wall. Thus, morphological change near a wall causes wall-following behavior, facilitating the identification of these narrow anchoring sites. Our findings indicate that environmental geometry drives behavioral transitions in S. coeruleus through simple biophysical processes, enabling spatial selection without visual cues. Overall, these results suggest that microgeometry plays a key role in shaping ecological niches for unicellular microorganisms.

Chromosomal Fusions Shaped the Genome of the Greater Hornwrack Bryozoan (Flustra Foliacea) (Linnaeus, 1758).
The Journal of heredity pii:8497176 [Epub ahead of print].
The phylum Bryozoa is an understudied, yet commonly-occurring, globally distributed bilaterian metazoan organismal group. They have a colonial lifestyle and an evolutionary history that spans at least 480 million years but likely longer. Despite their contentious phylogenetic affinities among metazoans, disproportionately few genomic investigations have been performed thus far. Here, we describe the first chromosome-level genome assembly of an individual Flustra foliacea colony belonging to the order Cheilostomatida, collected in southern Norway. The haplotype-resolved assembly of F. foliacea contains two pseudo-haplotypes spanning 956 megabases and 880 megabases, respectively. Both assemblies are highly complete both in terms of scaffolding (>90% of sequences placed in 8 autosomal chromosomal pseudomolecules), and gene content (BUSCO completeness scores > 90%). We also present gene and repeat annotations of the two assemblies. A comparison of our newly sequenced F. foliacea with five previously published bryozoan genomes supports the hypothesis that the group has undergone extensive genome rearrangements. This includes multiple chromosomal fusions in F. foliacea since their split with other cheilostome bryozoans. These fusions were enriched with long terminal repeat (LTR) retrotransposons, highlighting the complex interplay between genome organization and genomic repeats. Our study contributes to a deeper understanding of bryozoan genome evolution and the role of repeats in metazoan genome organization.

They have a colonial lifestyle and an evolutionary history that spans at least 480 million years but likely longer. Despite their contentious phylogenetic affinities among metazoans, disproportionately few genomic investigations have been performed thus far. Here, we describe the first chromosome-level genome assembly of an individual Flustra foliacea colony belonging to the order Cheilostomatida, collected in southern Norway. The haplotype-resolved assembly of F. foliacea contains two pseudo-haplotypes spanning 956 megabases and 880 megabases, respectively. Both assemblies are highly complete both in terms of scaffolding (>90% of sequences placed in 8 autosomal chromosomal pseudomolecules), and gene content (BUSCO completeness scores > 90%). We also present gene and repeat annotations of the two assemblies. A comparison of our newly sequenced F. foliacea with five previously published bryozoan genomes supports the hypothesis that the group has undergone extensive genome rearrangements. This includes multiple chromosomal fusions in F. foliacea since their split with other cheilostome bryozoans. These fusions were enriched with long terminal repeat (LTR) retrotransposons, highlighting the complex interplay between genome organization and genomic repeats. Our study contributes to a deeper understanding of bryozoan genome evolution and the role of repeats in metazoan genome organization.},

Spatial Distribution and Environmental Risk Assessment of Neonicotinoids, Antibiotics, and Heavy Metals in the Yellow River Riparian Soils.
Environmental management, 76(4):.
Co-occurring contaminants in riparian soils posed a growing threat to the sustainable development of the Yellow River Basin. However, understanding of the co-occurrence patterns and key drivers of heavy metals (HMs), antibiotics, and neonicotinoid insecticides (NNIs) at the watershed scale remains limited. Therefore, we selected surface soil along the Yellow River to analyze its content characteristics, spatial patterns, and interrelationships. Detection rates of NNIs, antibiotics, and HMs in soils exceeded 99%. The average content of total NNIs (∑8NNIs) was 5.118 ng/g, with thiacloprid (1.667 ng/g) being the predominant component (32.5%). Total antibiotics averaged 0.412 ng/g, dominated by quinolones (47.8%) and macrolides (30.9%). The concentrations of As, Cr, and Zn among the HMs were 5.7-18.0 μg/g, 53.4-91.1 μg/g, and 35.6-94.3 μg/g, respectively, exceeding their background values at 36%, 21%, and 37% of the sampling sites, respectively. Soil organic matter content and pH negatively correlated with NNIs but positively with HMs, while fine soil particles positively correlated with both. Furthermore, ∑8NNIs (7.680 ng/g) and the contents of thirteen antibiotics (∑13ABX, 13.956 ng/g) in corn-cultivated soils were higher than in other cropped types, while ∑8NNIs (0.780 ng/g) and ∑13ABX (0.003 ng/g) in reed marshes were lower than in other cultivated soils. Health and ecological risks were generally low across the study area, but some specific sites posed potential integrated contamination risks. The study provided scientific data on the environmental fate and risks of NNIs, antibiotics, and HMs in riparian soils of large-scale watersheds, and underscored the need for more efficient usage practices and integrated watershed management strategies.

A short-term association between hospitalizations for mental disorders and ambient temperature in Japan: an ecological study using the LIFE Study data.
Environmental health and preventive medicine, 31:12.
BACKGROUND: Few studies have investigated the association between ambient temperature and the risk of mental disorders in Japan. In this study, we investigated a short-term association between the risk of hospitalizations for mental disorders and ambient temperature using municipal health insurance data.
METHODS: We used the data of the Longevity Improvement & Fair Evidence Study in Japan, and the data of 17 municipalities were employed in the analysis. The daily number of hospitalizations for schizophrenia, depressive disorders, and anxiety disorders was used as the outcome variable. The time-stratified case-crossover design was employed in this ecological time-series study, and a distributed-lag non-linear model using a conditional quasi-Poisson regression model was employed to investigate an association between ambient temperature and hospitalizations for the abovementioned mental disorders. The model was applied to each municipality, and a multivariate meta-analysis was conducted to pool the results of municipalities. In addition, subgroup analyses by sex and age groups were conducted, and temperature-related attributable fractions of the mental disorders were also calculated.
RESULTS: The results of the overall cumulative effect of ambient temperature on hospitalizations for mental disorders indicated that the risk ratio (RR) tended to increase with an increase in temperature regardless of the type of mental disorder. An analysis by sex indicated that the RR tended to increase with an increase in temperature regardless of sex. In addition, an analysis by age group indicated that an increase in RR with increasing temperature was more evident in persons aged <65 years compared to those aged ≥65 years regardless of mental disorders, and that the temperature-related attributable fractions were also higher in persons aged <65 years.
CONCLUSIONS: Higher temperatures were associated with a higher risk of hospitalization for mental disorders in Japan, while the degree of the association differed by age group.

Environmental Drivers and Trophic Transfer of Domoic Acid in a Eutrophic Subtropical Estuary: Linking Toxigenic Pseudonitzschia Dynamics to Ecosystem Risks.
Environmental science & technology [Epub ahead of print].
Domoic acid (DA), a neurotoxin produced by certain diatoms of Pseudonitzschia, poses significant risks to marine ecosystems and human health, yet its dynamics in subtropical eutrophic estuaries remain poorly understood. This study investigates DA production and trophic transfer in the Pearl River Estuary, combining chemotaxonomy, morphological identification, ITS1 metabarcoding, and HPLC-MS/MS analysis. We revealed strong seasonal and spatial heterogeneity in Pseudonitzschia assemblages, identifying Pseudonitzschia cuspidata Clade III as a dominant DA producer with an estimated in situ cellular quota of 0.1-0.8 pg cell[-1] for the community. DA was ubiquitously detected across trophic levels, with summer maxima in phytoplankton to zooplankton, crustaceans, and mollusks, exceeding safety thresholds with 24.1 mg kg[-1] in scallops. Baseline DA contamination persisted year-round, with this chronic risk amplified by increased summer diatom biomass. Crucially, DA production was governed by optimal salinity and temperature and linked to nutrient stoichiometry rather than absolute nutrient concentration; chronic high nutrient levels showed a negative correlation with DA production. These environmental drivers also influenced DA transfer efficiency, with summer conditions amplifying contamination despite sub-bloom cell densities. These findings reveal underestimated risks in subtropical estuaries, providing a critical framework for monitoring and managing DA contamination under climate variability.

Cell-based biohybrid sensing of a volatile aggregation pheromone component associated with the invasive red palm weevil.
Biosensors & bioelectronics, 302:118537 pii:S0956-5663(26)00169-7 [Epub ahead of print].
The red palm weevil (Rhynchophorus ferrugineus, RPW) is a highly destructive invasive pest of palm trees, causing severe agricultural and economic losses worldwide. Adult males release an aggregation pheromone, primarily (4RS,5RS)-4-methylnonan-5-ol (ferrugineol), which mediates colony formation and infestation within palm trunks. Because all life stages of this weevil are hidden inside the tree and remain undetected until fatal damage occurs, rapid and sensitive detection of pheromone emissions from the weevil colony is crucial for early detection and monitoring. However, practical sensor technologies capable of detecting this pheromone have not yet been established. Here, we report a cell-based biohybrid sensor capable of detecting pheromones in the vapor phase. This sensor employs HEK293 cells transiently co-expressing the RPW pheromone receptor RferOR1, its co-receptor RferOrco, and the genetically encoded fluorescent calcium indicator GCaMP. The specificity and sensitivity of these cells were first validated for ferrugineol in aqueous solution (0.1-10 μM), showing decreased responses at 100 μM indicative of non-monotonic behavior. The cells were then encapsulated in hydrogel matrices and integrated into a microwell array. We found that the resulting cell-based sensor exhibited a monotonic fluorescence response to ferrugineol across a broader concentration range (0.1-100 μM), likely due to moderated diffusion of ferrugineol within the hydrogel. Furthermore, the sensor successfully detected ferrugineol in the vapor phase at sub-ppm concentrations (0.1-100 ppm). These findings demonstrate that the developed sensor provides a technological basis for pheromone-detection systems for RPW monitoring, thereby extending the applicability of biohybrid sensing to ecologically relevant odorants.

Tree pollen allergen sensitization: Prevalence, risk factors, and geographic variation in the United States.
The journal of allergy and clinical immunology. Global, 5(3):100642.
BACKGROUND: Many tree pollens are associated with the pathogenesis of allergic disease.
OBJECTIVE: Our aim was to investigate prevalence, risk factors, and geographic variation of tree pollen sensitization in the United States.
METHODS: Results of specific IgE testing for pollen of 31 tree species were obtained from a single United States-wide clinical laboratory by physicians' requests submitted in 2014-2023. Tree pollen sensitization data were statistically analyzed with respect to prevalence, patterns, and relationship with demographic characteristics, clinical diagnoses, and geographic regions.
RESULTS: A total of 23,932,544 specific IgE tests, originating from 3,067,173 unique patients ranging in age from 0 to 85 years were identified. Males showed higher positivity rates across all tree species and age groups. In both sexes, positivity was highest in individuals aged 10 to 19 years and in patients with atopic dermatitis and asthma. Patients living in urban areas had higher rates of sensitization than patients in rural areas. Considerable differences in top sensitizers were identified across ecoregions, even among different ecoregions present within the same US state. Rates of cosensitization to allergen pairs were generally associated with phylogenetic proximity of species.
CONCLUSION: Factors associated with higher rates of tree pollen sensitization included being male, being a teenager, having atopic dermatitis, having asthma, and living in a specific ecologic region. Results from this study may be helpful to clinicians in counseling patients, as well as to laboratories designing geographically based allergen testing panels.

Triadic percolation on multilayer networks.
Physical review. E, 113(1-1):014313.
Triadic interactions are special types of higher-order interactions that occur when regulator nodes modulate the interactions between other two or more nodes. In the presence of triadic interactions, a percolation process occurring on a single-layer network becomes a full fledged dynamical system, characterized by period doubling and a route to chaos. Here we generalize the model to multilayer networks and name it as the multilayer triadic percolation (MTP) model. We find a much richer dynamical behavior of the MTP model than its single-layer counterpart. MTP displays a Neimark-Sacker bifurcation, leading to oscillations of arbitrarily large period or pseudoperiodic oscillations. Moreover, MTP admits period-two oscillations without negative regulatory interactions, whereas single-layer systems only display discontinuous hybrid transitions. This comprehensive model offers new insights on the importance of regulatory interactions in real-world systems such as brain networks, climate, and ecological systems.

Relationship between time spent in outdoor recreational areas and stress among parents during the COVID-19 lockdown - A spatial temporal analysis of GPS traces from geographical EMA.
Spatial and spatio-temporal epidemiology, 56:100782.
BACKGROUND: The early COVID-19 period, with stay-at-home orders, was particularly stressful for parents. Outdoor recreation areas (ORAs), such as green spaces, may have helped alleviate stress.
AIM: To estimate the association between ORA visits and self-reported stress using geographical ecological momentary assessment (gEMA) with refined multi-sourced ORA boundaries.
METHODS: Self-reported stress was collected from a cohort of 286 participants via EMA three times daily over 14 days, alongside continuous GPS tracking. ORA visit durations were derived by spatio-temporal clustering of GPS tracks. Generalized ordinal logistic regression model supporting partial proportional odds was used to estimate the association between ORA visit duration stress, adjusting for baseline covariates and weather.
RESULTS: A minute-wise increase in ORA visit duration was not significantly associated with stress (Odds Ratio=0.99; 95% CI: 0.99 to 1.00). However, when the duration was categorized, ORA visits lasting between 15 and 35 min were associated with a 40% reduction in the odds of reporting higher stress (95% CI: 10% to 60%). A similar association was observed for shorter ORA visits (≤ 5 min), though the effect varied across stress levels. The odds of reporting higher stress were also associated with whether the parent was with their focal child, parental sex, marital status, work status, the time of day, and weekday/weekend.
CONCLUSION: Spending 15-35 min in ORAs may be optimal for parents to manage stress during challenging periods, such as the stay-at-home phase of the COVID-19 pandemic. Even brief ORA visits (< 5 min) may help parents experiencing high stress.

Research priorities for data science and artificial intelligence in global health: an international consensus exercise.
The Lancet. Global health, 14(3):e455-e465.
Applications of data science and artificial intelligence (AI) in global health are expanding, yet research remains fragmented and often misaligned with the needs of low-income and middle-income countries (LMICs). To address this misalignment, we conducted a global research priority-setting exercise using the Child Health and Nutrition Research Initiative (CHNRI) method. 155 research ideas were scored by 51 experts based on feasibility, potential impact on disease burden, paradigm shift potential, implementation potential, and equity. Top-ranked priorities focused on epidemic preparedness, including AI-based outbreak prediction, improved diagnostics for infectious diseases, and early-warning systems. Other highly ranked topics included AI-assisted resource allocation, telemedicine, culturally adapted mobile health services, and chronic disease management tools. Experts from LMICs prioritised infectious disease control and diagnostic equity, whereas experts from high-income countries emphasised infrastructure and climate-related analytics. The resulting agenda provides a roadmap for aligning AI and data science research with global health priorities, particularly in LMICs.

abstract = {Applications of data science and artificial intelligence (AI) in global health are expanding, yet research remains fragmented and often misaligned with the needs of low-income and middle-income countries (LMICs). To address this misalignment, we conducted a global research priority-setting exercise using the Child Health and Nutrition Research Initiative (CHNRI) method. 155 research ideas were scored by 51 experts based on feasibility, potential impact on disease burden, paradigm shift potential, implementation potential, and equity. Top-ranked priorities focused on epidemic preparedness, including AI-based outbreak prediction, improved diagnostics for infectious diseases, and early-warning systems. Other highly ranked topics included AI-assisted resource allocation, telemedicine, culturally adapted mobile health services, and chronic disease management tools. Experts from LMICs prioritised infectious disease control and diagnostic equity, whereas experts from high-income countries emphasised infrastructure and climate-related analytics. The resulting agenda provides a roadmap for aligning AI and data science research with global health priorities, particularly in LMICs.},

Maternal Screen-Related Behaviors, Toddler Screen Use, and Toddler BMI in Mexican American Families: Cross-Sectional Study.
JMIR pediatrics and parenting, 9:e76873.
BACKGROUND: Parents, as the most proximal influence on young children, play an important role in shaping toddler behaviors. Yet, evidence on how parents shape toddler screen use is limited. Little is also known about the relationship between toddler screen use and BMI. Given existing disparities in screen use and early childhood obesity, a focus on Mexican American families with toddlers is warranted.
OBJECTIVE: This study aimed to evaluate the independent contributions of both maternal screen use and screen-related parenting practices with toddler screen use duration, for both TV viewing and mobile device use, and examine the relationship between toddler screen use duration and BMI.
METHODS: This cross-sectional study enrolled 384 Mexican American mother-toddler dyads recruited from safety net clinics. Enrolled mothers completed 7-day screen use diaries and surveys on screen-related parenting practices, and toddler anthropometrics were obtained. Negative binomial regression models estimated the relationships between screen-related parenting practices and maternal screen use (predictors) with child duration of daily TV use and mobile device use (outcomes). Spearman correlations were calculated to estimate the relationship between toddler screen use duration and age- and sex-specific BMI z scores.
RESULTS: Maternal duration of daily TV and mobile device use were associated with toddler duration of daily TV (adjusted rate ratios [aRRs] 1.27-1.28; all P<.001) and mobile device use (aRRs 1.17-1.18; all P<.001), respectively, even after adjusting for maternal screen-related parenting practices. Specific parenting practices, including restriction of TV time (aRR=0.86; P=.01), restriction of mobile device time (aRR=0.80; P=.02), use of TV (aRR=1.27; P=.003) and mobile devices (aRR=1.78; P<.001) for child behavior regulation, and coviewing of mobile devices (aRR=1.51; P<.001), were associated with toddler duration of daily screen use, adjusted for maternal duration of daily screen use. Neither toddler duration of daily TV viewing nor daily mobile device use was correlated with toddler BMI z scores.
CONCLUSIONS: Both the duration of maternal screen use and screen-related parenting practices, for both TV and mobile devices, should be considered when promoting healthy screen use in toddlers in Mexican American families. Interventionists should consider the family ecology when designing interventions promoting healthy screen use in early childhood.

Framing the Convergence of One Health and Digital Health in the Global South With a Gender-Sensitive Foresight Perspective: Delphi Study Using Latent Semantic Analysis.
Journal of medical Internet research, 28:e78702 pii:v28i1e78702.
BACKGROUND: The convergence of digital health and One Health represents an emergent paradigm in global health governance. While widely discussed in high-income settings, there is limited understanding of how this convergence is conceptualized in the Global South, particularly when viewed through a gender- and equity-sensitive foresight lens.
OBJECTIVE: This study aimed to map and classify expert discourse on digital health, One Health, and their convergence in the Global South using latent semantic analysis, with particular attention to structural drivers, emerging issues, weak signals, and gendered patterns of anticipation.
METHODS: A 3-round online Delphi survey was conducted with 45 experts from 19 countries across the Global South. Open-ended responses were analyzed using latent semantic analysis and stratified by gender. A foresight framework was applied to categorize topics as structural drivers, emerging issues, or weak signals, based on their temporal persistence, salience, and consensus.
RESULTS: In digital health, structural drivers included the systemic integration of digital technologies into public health systems, strategic alignment, and infrastructure development. Emerging issues comprised the adoption of artificial intelligence, chronic disease management via mobile health, and concerns about digital inclusion and interoperability. Weak signals included feminist digital ethics, trust in digital systems, and relational accountability-more frequently emphasized by female experts. In One Health, structural drivers were centered on intersectoral coordination, ecological integration, and the institutionalization of health-environment frameworks. Emerging issues encompassed anticipatory risk governance, food system sustainability, and the integration of environmental and population-level data. Weak signals included indigenous knowledge systems, subnational antimicrobial resistance governance, and structural underinvestment in ecological public health, with gendered divergence in framing. In the convergence discourse (digital health and One Health), structural drivers focused on the integration of digital surveillance systems, data infrastructures, and health information platforms to operationalize One Health. Emerging issues included climate-triggered system redesign, artificial intelligence and ecological monitoring, and the governance of cross-sectoral data. Weak signals pointed to algorithmic bias in zoonotic prediction, digital sovereignty in environmental health, and feminist critiques of convergence-all thematically rich but peripheral in consensus.
CONCLUSIONS: This study revealed a multilayered and gender-influenced foresight architecture shaping the future of digital health and One Health in the Global South. Structural drivers denote maturing domains of implementation, while emerging issues and weak signals highlight latent, often overlooked opportunities and tensions. Incorporating equity-sensitive and gender-aware foresight methods is essential for crafting inclusive and anticipatory health governance strategies.

Harnessing endophytes and Multi-Omics for sustainable Colchicine biosynthesis.
World journal of microbiology & biotechnology, 42(3):92.
Gloriosa superba, an endangered medicinal plant, serves as the principal natural source of colchicine, a vital alkaloid used for treating gout, arthritis, cancer, and various inflammatory disorders. However, its conventional extraction from plant tissues is constrained by low yield, ecological degradation, and conservation concerns, necessitating sustainable production alternatives. Emerging evidence indicates that colchicine biosynthesis is not solely plant-autonomous but is strongly influenced by endophytic microorganisms that function as active metabolic partners. Endophytic fungi and bacteria associated with G. superba enhance colchicine accumulation through elicitor-mediated signaling, transcriptional reprogramming, metabolic complementation, and modulation of pathway flux. This review presents a systems-level synthesis that integrates endophyte biology with multi-omics technologies and synthetic biology to redefine colchicine biosynthesis as a coordinated plant-microbe metabolic network. Integrated transcriptomic, proteomic, and metabolomic analyses have enabled mechanistic resolution of the colchicine pathway, including identification of key enzymes, regulatory nodes, and bottlenecks such as the cytochrome P450-mediated oxidative ring expansion central to tropolone alkaloid formation. These insights underpin rational metabolic engineering, CRISPR-based genome editing, and synthetic pathway reconstruction in heterologous microbial hosts. By explicitly linking mechanistic understanding with pathway engineering and biomanufacturing design, this review advances a coherent framework for eco-efficient, scalable colchicine production while supporting conservation of G. superba.

Composition, Structure, and Diversity of Rhizosphere Soil Microbial Community in Saffron (Crocus sativus) Affected by Root Bulb Rot.
Plant disease [Epub ahead of print].
Fusarium oxysporum, first identified in Yunnan Province as the causal agent of saffron corm rot, causes a destructive soil-borne disease that has become a devastating threat to saffron cultivation in Shangri-La, causing over 50% mortality. This pathogen infects saffron corms, leading to vascular browning and rot, ultimately causing plant death and severe production losses. Given the crucial role of the rhizosphere microbiome in plant immunity and soil ecology, deciphering pathogen-microbiome interactions is essential for developing sustainable disease-control strategies. High-throughput sequencing of ITS/16S rRNA (Illumina MiSeq) was combined with arbuscular mycorrhizal fungi (AMF) analysis to compare the community structures of fungi, bacteria, and AMF in the rhizosphere of healthy and diseased saffron. The effects of soil physicochemical factors on microbiome assembly were systematically evaluated. The rhizosphere microbiome of diseased plants was significantly dysregulated: (1) pathogen-related taxa (e.g., Lauriomyces) proliferated, while saprotrophic functional taxa (e.g., Mortierella elongata) underwent community restructuring; (2) disease-suppressive taxa (e.g., fususidium) were enriched, while symbiotic mycorrhizal fungi (AMF) essential for nutrient acquisition sharply declined; (3) the soil parameter-microbiome relationship changed under different health conditions:available phosphorus (AP) and available potassium (AK) drove the aggregation of pathogenic soil fungi, while pH/organic matter (OM) dominated the aggregation of healthy soil fungi; (4) Knufia and Phomopsis were important taxa regulating soil ammonia oxidation and plant vitality. Fusarium infection disrupts the rhizosphere balance by inhibiting beneficial symbionts and promoting the colonization of pathogenic or saprotrophic microorganisms, ultimately compromising the innate resistance of saffron. Our findings reveal the rhizosphere ecological mechanism underlying corm rot progression and provide a microbiome informatics framework for the selection of biocontrol agents and rhizosphere engineering. Moreover, the worker safety benefits from the reductions in psychic emanations mandate industry adoption.

Multi-scale analysis of ecosystem service values and their driving factors based on MGWR: A case study of Yellow River Delta efficient ecological economic zone.
Ecotoxicology and environmental safety, 311:119886.
The Yellow River basin has recently experienced intensified pressures from climate change and anthropogenic activities, causing severe ecological degradation and compromised ecosystem security. Enhanced ecological protection is critically important for maintaining regional equilibrium and sustainable development. The Yellow River Delta High-Efficiency Economic Development Zone was examined to investigate multi-grid-scale ecosystem service value (ESV) spatial patterns and drivers (2005-2020). ESV was first calculated using the equivalent factor method at 3 km, 7 km, and 10 km scales. Spatial distribution characteristics were subsequently revealed through autocorrelation analysis. Finally, spatial heterogeneity induced by natural and socio-economic drivers was analyzed using MGWR local regression coefficients. The results indicate that: (1) During 2005-2020, land-use ESV ranked: water bodies > farmland > grassland > forest > unutilized land > construction land, with eastern high-ESV zones expanding and southern low-ESV areas increasing; (2) Significant positive spatial autocorrelation (Moran's I > 0, Z > 2.58) was observed, weakening with scale. High-high clusters occurred in ecological-economic zones, contrasting low-low clusters in human activity areas, with stable overall patterns despite scale variations; (3) Significant spatial heterogeneity was driven by natural (DEM, slope; p < 0.05) and socio-economic factors, with GDP and population density gaining prominence by 2020; (4) Significant drivers increased dynamically from 9 (2005) to 12 (2020), confirming temporal evolution. This work establishes a scientific foundation for deltaic ecological restoration and informs precision conservation policies, with broader implications for global ecosystem sustainability.

Exploring the Cognitive and Behavioral Risks and Maintenance Factors of Hikikomori: Protocol for an Ecological Momentary Assessment Study.
JMIR research protocols, 15:e81384.
BACKGROUND: Hikikomori is a state of social withdrawal first identified in Japan and is gaining interest globally. Classically, hikikomori is described as a state of isolation within one's home, though recent conceptualizations have proposed a continuum of severity. Hikikomori frequently shares symptoms with depression, social anxiety, autism, and schizophrenia, as well as internet and gaming disorders. Clinical case studies and cross-sectional studies suggest that dysfunctional emotion regulation, familial support, and internet behaviors are proposed to contribute to the onset and maintenance of a withdrawn state, though they have not been explored longitudinally.
OBJECTIVE: This study aims to investigate affective, behavioral, and cognitive correlates of hikikomori symptoms, and how daily mood, social enjoyment, familial support, and internet usage may maintain a socially withdrawn state.
METHODS: A minimum of 84 participants aged between 18 and 60 years will complete self-report measures of hikikomori symptoms, internet addiction, depression, anxiety, autism, and fear of offending others before participating in 14 days of ecological momentary assessment surveys. Surveys will be delivered 5 times per day from 8 AM to 10 PM, measuring mood, internet behavior, familial relationships, social interaction frequency, anticipatory and consummatory enjoyment, sleep quality, and physical activity. Participants will repeat the self-report measure of hikikomori symptoms postmonitoring period.
RESULTS: Recruitment began in November 21, 2025. Data collection and analysis are scheduled to be completed by summer 2026, with the results also scheduled to be available by the end of summer 2026. Correlation and multiple regression analyses will investigate whether internet addiction, social anxiety, expressive suppression, fear of offending others, daily mood, internet use, social enjoyment, and familial support predict hikikomori symptoms. Time-lagged network analyses will explore the temporal dynamics of these relationships, and how these differ in those with high and low levels of hikikomori symptoms. Finally, time-lagged logistic regressions will explore which factors predict future social behavior.
CONCLUSIONS: This study will be the first to investigate currently proposed mechanisms underlying hikikomori, while also exploring the time-varying relationships between affect and social behavior. The results will provide initial evidence for factors that predict hikikomori symptoms, explore candidate mechanisms underlying hikikomori, and identify potential maintenance factors as targets for intervention.

Classically, hikikomori is described as a state of isolation within one's home, though recent conceptualizations have proposed a continuum of severity. Hikikomori frequently shares symptoms with depression, social anxiety, autism, and schizophrenia, as well as internet and gaming disorders. Clinical case studies and cross-sectional studies suggest that dysfunctional emotion regulation, familial support, and internet behaviors are proposed to contribute to the onset and maintenance of a withdrawn state, though they have not been explored longitudinally.
OBJECTIVE: This study aims to investigate affective, behavioral, and cognitive correlates of hikikomori symptoms, and how daily mood, social enjoyment, familial support, and internet usage may maintain a socially withdrawn state.
METHODS: A minimum of 84 participants aged between 18 and 60 years will complete self-report measures of hikikomori symptoms, internet addiction, depression, anxiety, autism, and fear of offending others before participating in 14 days of ecological momentary assessment surveys. Surveys will be delivered 5 times per day from 8 AM to 10 PM, measuring mood, internet behavior, familial relationships, social interaction frequency, anticipatory and consummatory enjoyment, sleep quality, and physical activity. Participants will repeat the self-report measure of hikikomori symptoms postmonitoring period.
RESULTS: Recruitment began in November 21, 2025. Data collection and analysis are scheduled to be completed by summer 2026, with the results also scheduled to be available by the end of summer 2026. Correlation and multiple regression analyses will investigate whether internet addiction, social anxiety, expressive suppression, fear of offending others, daily mood, internet use, social enjoyment, and familial support predict hikikomori symptoms. Time-lagged network analyses will explore the temporal dynamics of these relationships, and how these differ in those with high and low levels of hikikomori symptoms. Finally, time-lagged logistic regressions will explore which factors predict future social behavior.
CONCLUSIONS: This study will be the first to investigate currently proposed mechanisms underlying hikikomori, while also exploring the time-varying relationships between affect and social behavior. The results will provide initial evidence for factors that predict hikikomori symptoms, explore candidate mechanisms underlying hikikomori, and identify potential maintenance factors as targets for intervention.},

COPE-EMBRACE: Coping with stress after encephalitis using real-time assessment.
Neuropsychological rehabilitation [Epub ahead of print].
Encephalitis can cause acquired brain injury due to inflammation, leading to cognitive issues and fatigue, exacerbating daily stress. Knowledge of real-time stress coping mechanisms among people post-encephalitis and how this relates to depression is limited. Ecological momentary assessment (EMA) may address limitations in standardized cross-sectional self-report assessments. This study evaluates the feasibility and acceptability of collecting EMA data on mood and coping. Twenty adults post-encephalitis (12 women, age range 26:67) completed daily and self-initiated EMA for mood and coping over 4 months, and post-study interviews explored acceptability using framework analysis. Average daily compliance rate was 79.3% (range 37.3-97.5%), showing EMA's feasibility, though low self-initiated EMA usage indicated challenges. Linear mixed-effects model revealed significant relationships between coping style and depression levels within individuals and over time. Framework analysis categorized two themes: "Encephalitis experience and its relationship to stress response" and "Experience of EMA: barriers and facilitators'. Qualitative analysis indicated acceptability for the m-Path app and measuring daily mood. Results suggest long-term daily EMA is feasible for collecting mood and coping in adults with encephalitis. However, patient and public involvement should be utilized to establish suitability. Following adaptations, EMA may serve as a psychological intervention targeting stress coping in daily life.

"I know a lot about medicinal plants. I read, I watch, and I search": towards hybrid knowledge systems in the modern era.
Journal of ethnobiology and ethnomedicine, 22(1):14.
BACKGROUND: Hybrid knowledge systems are central to community negotiations of environmental, social, and epistemic pressures. In multilingual borderland areas, interactions between local ecological knowledge (LEK), formal, and popular knowledge systems remain underexplored, despite their importance for the persistence and transformation of medicinal plant use today.
METHODS: We conducted 67 semi-structured interviews and participant observation in 21 rural settlements of the Vilnius region (Lithuania), an area bordering Belarus, focusing on the two largest local groups, Lithuanians (LT) and Poles (PL). Detailed Use Reports (n = 1446) on medicinal plant use were coded by the origin of knowledge, classified as local, formal, or popular, and the degree of hybridisation was quantified using the Shannon-Wiener diversity index and hybridisation metrics. Sociodemographic variables (age, gender, education, and multilingualism) were tested for associations with hybridisation using Spearman's ρ and Student's t-tests.
RESULTS: A total of 139 medicinal taxa were recorded, of which 68 (49%) were shared between the two groups. Overall, recorded medicinal plant knowledge remained primarily grounded in LEK, sustained through intergenerational transmission. Compared with PL, LT interviewees drew on a broader mix of knowledge-origin domains (H' = 0.97 vs 0.52) and combined them more often (HD = 0.195 vs 0.059). In total, 39 taxa showed hybrid use, predominantly in the LT group. Hybridisation was negatively associated with age but positively correlated with the number of listed plants and their reported uses, while multilingualism showed a near-significant positive trend.
CONCLUSIONS: The study suggests that medicinal plant knowledge has evolved here through hybridisation, a process whose consequences are context-dependent, offering opportunities for revitalisation but also a risk of displacement. Dialogic exchanges across families, communities, languages, and media expand people's plant repertoire and strengthen community adaptive capacity. Yet when these exchanges lead to excessive standardisation, they risk eroding the diversity of local traditions. Ethnobotanical research must therefore go beyond documenting popular and formal knowledge sources to interrogate how linguistic and sociopolitical contexts condition the emergence of hybrid knowledge systems, privileging certain forms while rendering others transformed or marginalised.

Large-scale environmental DNA survey reveals niche axes of a regional coastal fish community.
Scientific reports, 16(1):3276.
The concept of the ecological niche, defined as the basic habitat requirements for a species, is central to understanding species geographic distributions and predicting their responses to environmental change. However, identifying the essential niche for large regional communities remains a challenge because niche axes can be "hidden" by the complexity of the underlying ecological processes. Here, applying advanced species distribution modelling to nationwide environmental DNA survey data, we identified hidden niche axes of the Japanese coastal fish community and investigated the response diversity to these axes. Our survey detected 1,220 coastal fish species. The hidden niche axes collectively explained most of the variation in fish biodiversity and revealed five biogeographic boundaries for the regional community. These niches of the Japanese fish community may primarily relate to several processes due to ocean currents, such as environmental filters, transport from source areas and dispersal barriers. We also found that the response diversity to niche axes was positively correlated with species richness, although local communities with particularly high response diversity were geographically biased. A better understanding of the niche axes of the regional ecological community should help to mitigate the loss of biodiversity and ecosystem services caused by ongoing environmental change.

The genome sequence of the 24-spot ladybird, Subcoccinella vigintiquattuorpunctata (Linnaeus, 1758) (Coleoptera: Coccinellidae).
Wellcome open research, 10:698.
We present a genome assembly from an individual female Subcoccinella vigintiquattuorpunctata (24-spot ladybird; Arthropoda; Insecta; Coleoptera; Coccinellidae). The genome sequence has a total length of 532.03 megabases. Most of the assembly (97.41%) is scaffolded into 15 chromosomal pseudomolecules, including the X sex chromosome. The mitochondrial genome has also been assembled, with a length of 18.91 kilobases. This assembly was generated as part of the Darwin Tree of Life project, which produces reference genomes for eukaryotic species found in Britain and Ireland.

The formation of bioavailable Hg in a pipeline: An initial investigation into Hg bioaccumulation resulting from oil and gas decommissioning.
The Science of the total environment, 1019:181526.
Mercury (Hg) released during offshore pipeline decommissioning may pose ecological risks, yet little is known about its chemical form and biological impact. We examined how Hg[0] can react on and subsequently be released from laboratory-generated steel pipeline material to interact with marine algae, focusing on chemical speciation, transformation, and cellular uptake. Laboratory exposures of the marine algae, Isochrysis galbana, to pipeline-derived Hg showed accumulation up to 109 mg kg[-1] dry weight, as determined by cold vapour atomic fluorescence spectrometry (CV-AFS). Single-cell inductively coupled plasma mass spectrometry (SC ICP-MS) confirmed substantial cell-associated Hg, with bimodal distributions suggesting distinct uptake or surface-association pathways. Although classical growth and photosynthetic parameters did not consistently reveal toxicity, Hg exposure altered cell populations and aggregation behaviour, indicating sublethal but ecologically relevant effects. Our findings demonstrate that through interactions with pipeline material Hg[0] can be transformed into species which have an increased likelihood of bioaccumulation.

Emerging contaminants during arctic rain-on-snow events: A case study from the 2023-24 Ny-Ålesund campaign.
Environmental pollution (Barking, Essex : 1987), 395:127790.
The Svalbard Archipelago has undergone rapid warming in recent decades, increasing the frequency and intensity of Rain-on-Snow (ROS) events. While the physical and ecological consequences of ROS in the Arctic have been extensively documented, their role in modulating the atmospheric fate of emerging contaminants remains poorly understood. This study investigates the chemical signature of four ROS events during the 2023-24 field campaign in Ny-Ålesund (Kongsfjorden, Svalbard, Norway), focusing on the behaviour of emerging pollutants across pre-, during-, and post-event phases. By combining aerosol and wet deposition data with meteorological variables and air mass back-trajectories, we explore the potential of ROS to act as removal mechanisms for benzothiazole derivatives, tris(2-carboxyethyl) phosphine (TCEP) as flame retardant, pesticides, and haloacetic acids. The results highlight a substantial variability in contaminant patterns across events and suggest the influence of synoptic-scale air mass origin and local meteorological conditions. Diagnostic ratios and inorganic ion proxies provide insight into possible atmospheric transformation pathways and transport processes. This study provides the first detailed chemical characterisation of aerosol and depositions during Rain-On-Snow events, establishing a preliminary framework to better understand the complex interactions between ROS and contaminant cycling in a warming Arctic. This work contributes to ongoing efforts to clarify the mechanisms of atmospheric scavenging under changing climate conditions.

SWAT-WASP coupled modeling of ammonia nitrogen in rare earth mining watersheds.
Water science and technology : a journal of the International Association on Water Pollution Research, 93(3):273-295.
High concentrations of ammonia nitrogen (NH4[+]-N) are a dominant water pollutant in ionic rare earth mining basins, threatening aquatic ecosystems and drinking-water safety. To quantify these dynamics, this study developed a coupled SWAT-WASP model for the upper Dongjiang River Basin (UDRB), integrating remote sensing and long-term monitoring data; the model was calibrated and validated with 2016-2018 monthly observations, and quantitative evaluation via Nash-Sutcliffe Efficiency (NSE) and Percent Bias (PBIAS) showed good performance (runoff: NSE = 0.77-0.80; NH4[+]-N: SWAT NSE = 0.56-0.61, SWAT-WASP NSE = 0.65-0.87), confirming its reliability. 2022 simulations revealed strong NH4[+]-N spatial heterogeneity, with concentrations >1.8 mg L[-1] near mining zones versus <0.5 mg L[-1] in upstream natural areas; geodetector analysis identified population density combined with industrial-agricultural activity as the top driver of spatial differentiation (q > 0.40), while interactions between precipitation, temperature, and land use further amplified variability. Overall, the SWAT-WASP framework provides a robust tool for evaluating NH4[+]-N dynamics and supports targeted pollution control and ecological restoration in rare earth mining watersheds.

A Transcriptome Study on Seed Germination of Nitraria roborowskii Kom.
International journal of molecular sciences, 27(3):.
Nitraria roborowskii Kom. seeds possess pronounced deep dormancy traits. Analyzing changes in gene expression before and after dormancy release is of great significance for elucidating the mechanisms underlying seed dormancy. In this study, transcriptome sequencing and bioinformatics analysis were conducted on N. roborowskii seeds both before and after dormancy release using high-throughput Illumina NovaSeq 6000 sequencing technology. The key findings are as follows: (1) A total of 215,303 transcripts and 84,450 unigenes were obtained through de novo assembly. (2) Comparative analysis revealed 16,130 significantly differentially expressed unigenes during germination, with 10,776 upregulated and 5354 downregulated. Gene Ontology (GO) enrichment analysis indicated that these differentially expressed genes (DEGs) were primarily associated with biological processes and molecular functions, mainly involved in metabolic processes and catalytic activities. (3) Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed that the DEGs were predominantly enriched in pathways such as plant hormone signal transduction and starch and sucrose metabolism. Specifically, among the downregulated genes, 126 were linked to plant hormone signal transduction, 110 to phenylpropanoid biosynthesis, 108 to starch and sucrose metabolism, 27 to flavonoid biosynthesis, 20 to plant hormone signal transduction, 6 to phenylpropanoid metabolism, 14 to starch and sucrose metabolism, and none to flavonoid biosynthesis.

(2) Comparative analysis revealed 16,130 significantly differentially expressed unigenes during germination, with 10,776 upregulated and 5354 downregulated. Gene Ontology (GO) enrichment analysis indicated that these differentially expressed genes (DEGs) were primarily associated with biological processes and molecular functions, mainly involved in metabolic processes and catalytic activities. (3) Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed that the DEGs were predominantly enriched in pathways such as plant hormone signal transduction and starch and sucrose metabolism. Specifically, among the downregulated genes, 126 were linked to plant hormone signal transduction, 110 to phenylpropanoid biosynthesis, 108 to starch and sucrose metabolism, 27 to flavonoid biosynthesis, 20 to plant hormone signal transduction, 6 to phenylpropanoid metabolism, 14 to starch and sucrose metabolism, and none to flavonoid biosynthesis.},

Transcriptomic Responses of Sclerodermus alternatusi Yang to Ultraviolet (UV) Stress of Different Wavelengths.
International journal of molecular sciences, 27(3):.
Ultraviolet (UV) radiation is a significant environmental stressor that exerts profound impacts on insect physiology, behaviour and survival. Although some insects can use UV light for spatial orientation and navigation, it can induce DNA damage, oxidative stress, and impair critical biological functions, ultimately reducing ecological fitness. Sclerodermus alternatusi Yang (Hymenoptera: Bethylidae) is a dominant ectoparasitoid of the early instar larvae of Monochamus alternatus and plays a key role in the biological control of this pest in forestry systems; however, it faces intense UV exposure in the field environment. Despite its ecological importance, the molecular mechanisms underlying its responses to UV-induced stress remain poorly understood. In this study, newly emerged adult wasps (within 24 h post-eclosion) were exposed to UVA (365 nm) and UVC (253.7 nm) radiation for 9 h under controlled laboratory conditions. Total RNA was extracted from treated and control individuals for transcriptomic analysis using RNA-Seq. A total of 505 differentially expressed genes (DEGs) were identified; gene ontology enrichment analysis revealed that UVA exposure significantly upregulated genes involved in cellular respiration and oxidative phosphorylation, suggesting an enhanced metabolic response. Furthermore, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that UV stress modulates energy metabolism through the activation of oxidative phosphorylation and thermogenesis-related pathways, highlighting the reallocation of energy resources in response to UV-induced stress. To validate the RNA-Seq data, four representative DEGs were selected for quantitative real-time PCR (RT-qPCR) analysis. The qPCR results were consistent with the transcriptomic trends, confirming the reliability of the sequencing data. Collectively, this study provides a comprehensive overview of the molecular response mechanisms of S. alternatusi to UV stress, offering novel insights into its environmental adaptability and laying a theoretical foundation for its application in biological pest control under field conditions.

Methodologies for Assessing Chemical Toxicity to Aquatic Microorganisms: A Comparative Review.
Molecules (Basel, Switzerland), 31(3):.
Aquatic ecological issues have garnered significant attention in recent years, driving the demand for convenient, effective, and systematic assessment methods in environmental risk evaluation. This review provides a comprehensive introduction to methodologies for assessing the toxicity of chemicals toward aquatic microorganisms, which include viruses, bacteria, fungi, protozoa, and algae. Among these, microalgae are commonly used as model organisms due to their relative simplicity. The article details conventional biological methods, general chemical techniques, modern instrumental analyses, and informatics approaches, with a particular focus on algae and bacteria as model organisms for toxicity assessment. The principles, advantages, and limitations of each method are discussed, along with examples of their application in various contexts. Biological methods offer direct visualization, convenience, and rapid results, while modern instrumental techniques enable mechanistic insights at molecular and biochemical levels. Informatics methods facilitate toxicity evaluation in complex systems. While aquatic microorganisms encompass viruses, fungi, protozoa, bacteria, and algae, this review primarily focuses on bacteria and algae as model organisms due to their ecological relevance, sensitivity, and widespread use in standardized assays.

Integrated Molecular Informatics and Sensory-Omics Study of Core Trace Components and Microbial Communities in Sauce-Aroma High-Temperature Daqu from Chishui River Basin.
Foods (Basel, Switzerland), 15(3):.
Flavor-relevant trace volatiles and microbial communities were examined in six sauce-aroma high-temperature Daqu samples. Headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME-GC-MS) quantified 210 trace volatile compounds across 14 chemical classes. Orthogonal partial least squares discriminant analysis (OPLS-DA) with variable importance in projection (VIP) screening was integrated with sensory scoring, correlation analysis, and molecular docking to an olfactory receptor model. Volatile profiles showed clear stratification in total abundance. Pyrazines dominated the high-total group. Tetramethylpyrazine served as a major driver. Sensory evaluation indicated that aroma explained overall quality best. (E)-2-pentenal and dimethyl trisulfide showed significant positive associations with aroma and overall scores. In the olfactory receptor, the polar residue module that provides directional constraints for Daqu odor activation was formed by Ser75, Ser92, Ser152, Ser258, Thr74, Thr76, Thr98, Thr200, Gln99, and Glu94. The hydrogen-bond or charge network was further reinforced by Arg150, Arg262, Asn194, His180, His261, Asp182, and Gln181. The core discriminant set comprised acetic acid, hexanoic acid, (E)-2-pentenal, nonanal, decanal, dimethyl trisulfide, trans-3-methyl-2-n-propylthiophane, 2-hexanone oxime, ethyl linoleate, propylene glycol, 2-ethenyl-6-methylpyrazine, 4-methylquinazoline, 5-methyl-2-phenyl-2-hexenal, and 1,2,3,4-tetramethoxybenzene. Sequencing revealed higher bacterial diversity than fungal. Bacillus and Kroppenstedtia were dominant bacterial genera. Aspergillus, Paecilomyces, Monascus, and Penicillium were major fungal genera. Correlation patterns suggested that Bacillus and Monascus were positively linked to acetic acid and 1,2,3,4-tetramethoxybenzene. Together, these results connected chemical fingerprints, sensory performance, receptor-level plausibility, and microbial ecology. Concrete targets are provided for quality control of high-temperature Daqu.

Context-Aware Multi-Agent Architecture for Wildfire Insights.
Sensors (Basel, Switzerland), 26(3):.
Wildfires are environmental hazards with severe ecological, social, and economic impacts. Wildfires devastate ecosystems, communities, and economies worldwide, with rising frequency and intensity driven by climate change, human activity, and environmental shifts. Analyzing wildfire insights such as detection, predictive patterns, and risk assessment enables proactive response and long-term prevention. However, most of the existing approaches have been focused on isolated processing of data, making it challenging to orchestrate cross-modal reasoning and transparency. This study proposed a novel orchestrator-based multi-agent system (MAS), with the aim of transforming multimodal environmental data into actionable intelligence for decision making. We designed a framework to utilize Large Multimodal Models (LMMs) augmented by structured prompt engineering and specialized Retrieval-Augmented Generation (RAG) pipelines to enable transparent and context-aware reasoning, providing a cutting-edge Visual Question Answering (VQA) system. It ingests diverse inputs like satellite imagery, sensor readings, weather data, and ground footage and then answers user queries. Validated by several public datasets, the system achieved a precision of 0.797 and an F1-score of 0.736. Thus, powered by Agentic AI, the proposed, human-centric solution for wildfire management, empowers firefighters, governments, and researchers to mitigate threats effectively.

Pathways, outputs and impact of NIH-supported bioinformatics and genomics graduate trainees in Africa.
Briefings in bioinformatics, 27(1):.
Global biomedical and health research is increasingly relying on genomic and computational approaches, largely driven by the increasing volumes of nucleic acid sequencing. Concurrently, epidemiological studies and clinical records are generating enormous amounts of data amenable to disease modeling, machine learning, and artificial intelligence techniques. Bioinformatics and data science expertise is therefore essential for improved population health. Accordingly, in 2012, the US National Institutes of Health (NIH) in partnership with the Wellcome Trust, and with support from the African Society for Human Genetics, initiated the H3Africa (Human Heredity and Health in Africa) consortium. One of its key goals was to build capacity among African scientists to lead research on genetic and environmental contributors to health and disease across the continent. In 2017, the NIH provided funding to support the establishment of four graduate bioinformatics training programs across five African universities. Over seven years, these programs enrolled multiple trainees (n > 270), with >110 earning Master's degrees and >20 completing PhDs in Bioinformatics. It is thus timely to evaluate the outcomes and impact of these programs, particularly regarding graduation rates, career trajectories, and the institutions and research domains their alumni are serving. We also assess employment outcomes and the nature of the research they are enabling (n > 110 peer-reviewed articles). We additionally include the progress and outputs of the programs' instructors, which were partially enabled by program resources, networks, and trainees. Overall, this review paints valuable insights into the pioneering role of NIH extramural support in shaping Africa's biomedical research landscape.

Evaluating paratransgenesis using engineered symbiotic bacteria for Plasmodium inhibition in mosquito vectors: A systematic review.
PLoS neglected tropical diseases, 20(2):e0013654.
Malaria is a significant health problem in the world and has been increased by the emerging resistance to insecticides and antimalarial drugs. New measures must therefore be implemented as an emergency to break the cycle of Plasmodium parasite transmission by the Anopheles mosquitoes. This systematic review assessed the effectiveness of paratransgenesis, an engineering approach that utilizes symbiotic microbes to deliver antiplasmodial molecules into the midgut of the mosquito as a transmission-blocking agent. PubMed, ScienceDirect, and Web of Science were searched in accordance with the PRISMA guidelines, yielding 1,289 records. Ten eligible studies were then included after screening. The chosen articles studied bacterial and fungal symbionts, such as Asaia, Serratia, Pantoea, Enterobacter, and Aspergillus oryzae, that have been engineered to produce effector proteins, such as Scorpine, EPIP, Defensin, and SM1-2 peptides. The delivery of oral sugar meals was always associated with colonization of the mosquito midguts, and results reported high levels of inhibition of oocysts or sporozoites in the mosquitoes. Scorpine was the strongest and most commonly used effector with a high level of up to 97.8% inhibition of P. falciparum oocysts in various microbial systems. The combination of two or multiple-effector approaches increased the efficacy in some cases, surpassing 89% parasite inhibition. The risk of bias measurement showed moderate variation in the methods, yet it was in favor of the sound findings. All evidence suggests that paratransgenesis is a potentially important malaria control tool, complementing existing approaches to malaria control. Nevertheless, ecological safety, microbial stability, and field validation are the key obstacles before the translation to large-scale use.

The ecological origins of collectivism and individualism.
Psychological review pii:2027-28323-001 [Epub ahead of print].
Interdependent subsistence styles, such as rice farming, are thought to underlie the evolution of collectivistic cultures, which emphasize collective welfare over individual gains. Rice farming can produce mutual dependence within communities but also create conflicting interests, as people cooperate to provide valuable public goods. However, current theories of the origins of collectivism fail to address the interplay between mutual dependence and conflict. As a consequence of these limitations, the evolutionary dynamics of collectivism and its association with cooperation are still unclear. We advance a theoretical model to study the evolution of cultural traits that enhance people's valuations of collective welfare, one of the key features of collectivistic cultures. Our model investigates the evolutionary dynamics of cooperation and cultural evolution in ecologies with distinct interdependence structures. We find evidence that higher degrees of mutual dependence facilitate the evolution and persistence of collectivism. However, the degree of conflicting interests also plays a crucial role in driving the diffusion and maintenance of collectivistic norms. In particular, the selective advantage of collectivism is strongest when people experience some degree of conflict of interests, an effect that is magnified by heightened mutual dependence. These results clarify how variation in interdependence could underlie the ecological origins of collectivism, lending support to and expanding the scope of current theories of the cultural evolution of cooperation. More broadly, the framework presented here elucidates how fitness interdependence can be influenced by different ecological factors, and, in turn, influence the evolution of social behaviors.

More broadly, the framework presented here elucidates how fitness interdependence can be influenced by different ecological factors, and, in turn, influence the evolution of social behaviors.

Soil pH modulates microbial nitrogen allocation in soil via compositional and metabolic shifts across forests in Japan.
iMetaOmics, 2(4):e70054.
Ammonium release (ammonification) and uptake (immobilization) by soil microbial communities are fundamental processes of forest nitrogen (N) cycling, representing major N fluxes that influence plant productivity and ecosystem N retention. However, because these processes involve diverse metabolic pathways distributed across many taxa, they are difficult to evaluate using gene- or taxon-specific approaches, and it remains unclear how microbial community structure governs the patterns of these processes. In this study, we examined how the abundance, taxonomic composition, richness, and metabolic capabilities of microbial communities regulate ammonium-related N cycling processes across a wide range of forests in Japan, using rRNA gene sequencing and quantification, shotgun metagenomics, and [[15]]N tracer assays. Across the full gradients of soil pH and N content, microbial abundance was primarily correlated with the absolute rates of N cycling processes, while taxonomic composition and richness were more strongly correlated with N allocation-that is, the balance among ammonium release, ammonium uptake, and subsequent nitrification. Soils with higher pH supported taxonomic compositions linked to enhanced ammonium release and nitrification, whereas lower-pH soils hosted compositions associated with greater ammonium uptake and retention. Notably, the regulatory influence of taxonomic composition on N allocation was pronounced within the higher-pH range but diminished within the lower-pH range. Despite this environmental dependency, N allocation by soil microbial communities was ultimately constrained by their overall metabolic capabilities. In higher-pH soils, microbial communities were enriched in metabolic functions related to nutrient acquisition and respiratory N transformations, supporting increased ammonium release and N mobility. By contrast, microbial communities in lower-pH soils were enriched in stress-adaptive functions, which promoted ammonium retention and limited N transformations-thereby diminishing the regulatory influence in N cycling. Together, our findings provide a mechanistic understanding of how microbial community structure and metabolic capabilities regulate ammonium-related N cycling processes across forests under varying environmental conditions.

Sequence type and strain-level detection of Klebsiella pneumoniae in culture-enriched bacterial metagenomes: comparative performance of mSWEEP and StrainGE bioinformatic tools.
Microbial genomics, 12(2):.
Klebsiella pneumoniae is a major cause of human infections and is frequently associated with antimicrobial resistance (AMR). Carriage of K. pneumoniae in the gut is a major risk factor for infection and a reservoir for the spread of high-risk clonal lineages and associated AMR determinants. Accurate detection of K. pneumoniae at the subspecies level is therefore essential to better understand K. pneumoniae gut colonization ecology and clonal dissemination. We analysed two recently developed bioinformatic tools, mSWEEP and StrainGE, for sequence type (ST) detection of K. pneumoniae in culture-enriched sweep metagenomes compared to single-colony whole-genome sequencing (WGS). We show that both mSWEEP and StrainGE perform highly accurate ST detection, concordant with culture in 46/49 and 44/49 samples with WGS-detected single STs, respectively, as well as in 2/3 samples with two WGS-detected STs. Within-sample ST diversity was detected in 19 and 15 samples by mSWEEP and StrainGE, respectively, highlighting a major advantage of these tools over conventional single-colony WGS. StrainGE could also reconstruct accurate phylogenetic relationships between strains of the same ST for 2/3 different STs tested. Additionally, assembly of the genomes provides better resolution of ST detection by mSWEEP. Together, our results show that both mSWEEP and StrainGE are accurate tools for the detection and analysis of K. pneumoniae STs from mixed bacterial samples.

Detecting momentary reward and affect with real-time passive digital sensor data.
JAMIA open, 9(1):ooag005.
OBJECTIVES: This study explores the capability of passive digital sensor data from smartphones and smartwatches to predict self-reported ecological momentary assessments (EMA) of affect, motivation, interest, and pleasure in activities in an unseen test sample.
MATERIALS AND METHODS: Data were collected from 245 depressed participants with high-to-low anhedonia (195 train, 50 test) generating 23 812 EMA sessions. Machine learning models were used to assess the ability of behavioral and physiological features, aggregated over windows of 15 minutes to 3 hours, to predict momentary subjective states.
RESULTS: For 12 of 15 EMA questions asked, machine learning models exceeded random chance in the fully-held-out test sample, suggesting detectable signals between passive measures and subjective states. Dependent on the sensor type, the optimal aggregation periods ranged from 15 minutes to 3 hours, with generally at least two hours of data being required. Subgroup analyses revealed variations in model performance by demographics, depression severity, and anhedonia severity.
CONCLUSION: This study establishes the feasibility of using passive digital sensing to detect momentary subjective states, providing a baseline for scalable, non-invasive mental health monitoring.

Multi-omics profiling reveals associations between gut microbiota and olfactory gene expression in mosquitoes.
Frontiers in cellular and infection microbiology, 15:1745848.
INTRODUCTION: The interplay between gut microbiota and host physiological processes has been extensively studied in vertebrates, where it plays a crucial role in regulating appetite, emotion, immunity, and other physiological functions. However, whether a similar regulatory mechanism exists in insects remains unclear, especially regarding the long-distance regulation of olfactory function. This study focused on three Culex subspecies (Culex quinquefasciatus, Culex pipiens pallens, and Culex pipiens molestus) that are closely related but exhibit significant differences in olfaction-dependent ecological habits. By integrating antennal transcriptomic and gut metagenomic data, we systematically analyzed the expression characteristics of olfactory-related genes, the structure of gut microbial communities, and their intrinsic associations.
METHODS: We integrated antennal transcriptomic and gut metagenomic sequencing to analyze olfactory-related gene expression, gut microbial community structure, and their intrinsic associations in male and female individuals of the three Culex subspecies. Bioinformatics analyses included differential gene screening, functional enrichment, microbial taxonomic annotation, and Spearman correlation analysis.
RESULT: The results showed that a large number of sex-specific and species-specific differentially expressed genes (DEGs) were identified in the antennae of the three Culex subspecies. Among these, 345 DEGs were shared sex-specific genes across species, which were significantly enriched in pathways such as odor binding, signal transduction, and xenobiotic metabolism. At the phylum level, the gut microbial composition was dominated by Proteobacteria, Bacteroidetes, and Firmicutes, showing a conserved structure; at the genus level, 11 dominant genera (including Wolbachia, Elizabethkingia, and Asaia) exhibited distinct species-specific distribution patterns. Diversity analysis revealed that the gut microbial richness of male individuals was significantly higher than that of females, and the β-diversity showed an obvious "sex clustering" pattern.Correlation analysis further indicated that 152 DEGs were significantly correlated with 107 microbial genera. Among them, olfactory-related genes were closely associated with several core genera (e.g., Wolbachia, Asaia, Serratia). Gut microbes may remotely regulate the expression and function of olfactory genes in antennae through metabolites or signaling molecules, thereby influencing mosquito behaviors such as host localization, mating, and oviposition.
DISCUSSION: This study reveal the intrinsic association between gut microbes and olfactory function in Culex mosquitoes, providing a new perspective for understanding the "microbe-host" cross-organ regulatory mechanism and laying a theoretical foundation for the development of novel mosquito vector control strategies based on microbial or olfactory interference.

Community assembly modeling of the microbiome within Barrett's esophagus and esophageal adenocarcinoma.
BMC genomics, 27(1):.
UNLABELLED: Computational modeling of somatic evolution, a process shaped by ecology and impacting both host cells and microbial communities in the human body, can capture important dynamics driving carcinogenesis. Here we considered models for esophageal adenocarcinoma (EAC), a cancer that has dramatically increased in incidence over the past few decades in Western populations, with high case fatality rates due to late-stage diagnoses. Despite advancements in genomic analyses of the precursor Barrett’s esophagus (BE), prevention of late-stage EAC remains a significant clinical challenge. Previous microbiome studies in BE/EAC have focused on quantifying static microbial abundance differences rather than determining population dynamics. Using whole genome sequencing data from a total of 505 esophageal samples, we first applied a robust bioinformatics pipeline to extract non-host DNA reads, mapped these putative reads to microbial taxa, and retained those taxa with high genomic coverage. When applying mathematical models of demographic stochasticity to sequential stages of progression to EAC, we observed evidence of neutral dynamics in community assembly within normal esophageal tissue and BE, but not EAC. In a large case–control study of BE patients who progressed to EAC versus BE patients with non-cancer outcomes (NCO) during follow-up (mean = 10.5 years), we found that Helicobacter pylori deviated significantly from the neutral expectation in BE NCO only, suggesting that factors related to H. pylori or H. pylori infection itself may influence EAC risk. Additionally, stochastic simulations incorporating selection recapitulated non-neutral behaviors observed. Formally modeling dynamics during progression holds promise in clinical applications by offering a deeper understanding of microbial involvement in cancer development.

Multiomics Insights into the Ecotoxicological Effects of Soil Microplastics on Crop Plants.
Journal of agricultural and food chemistry, 74(7):5832-5844.
Microplastics (MPs) have become pervasive contaminants. This is due to plastic mulching, wastewater irrigation, and sludge application. Concentrations of MPs in intensive farming regions have been recorded at 41,741 particles/kg. MPs are absorbed by crop roots and leaves and then travel to reproductive organs. In these organs, they cause oxidative stress, genotoxicity, and toxicity, which disrupts nutrient uptake, photosynthesis, and crop yield. This review summarizes 20 years (2003-2024) of studies on MP-distribution in soil-crop systems and their phytotoxicity mechanisms, highlighting the pioneering role of multiomics methods. Genomic analyses show that MPs cause DNA damage and change the expression levels of stress-response genes. Transcriptomics identifies disrupted pathways. These pathways are in carbohydrate metabolism, plant hormones, and antioxidant defense. Proteomics uncovers post-translational modifications. These affect nutrient transporters. Metabolomics further highlights disturbances in glycolysis, amino acid synthesis, and ROS-scavenging metabolites. Despite these advances, integrating multiomics data sets to elucidate systemic "gene-protein-metabolite" networks remains challenging. Key knowledge gaps include MP-protein binding mechanisms, the development of crop-specific biomarkers, and the interaction of MPs with costressors. Future research should prioritize integrated transcriptomic-metabolomic profiling to identify stress-response pathways, use X-ray crystallography to map MP-protein interactions, and develop MP-resilient crop varieties. Multiomics integration is essential for decoding the toxicity of the MPs and formulating mitigation strategies to safeguard the sustainability of agriculture.

Environmental influences on community participation among people with multiple sclerosis: A mixed methods study.
PloS one, 21(2):e0342678 pii:PONE-D-25-44228.
OBJECTIVE: To examine the influence of environmental factors (EFs) and personal factors (PFs) on community participation among people with multiple sclerosis (PwMS) and identify areas for improvement.
METHODS: A mixed methods explanatory sequential design was used. A secondary data analysis of patient-reported outcomes and Global Positioning System (GPS) data was completed using multiple linear regression analysis to examine associations between five EFs, five PFs, and six community participation outcomes in 100 PwMS. Four focus groups were completed with 12 PwMS who use mobility aids and 12 who do not to understand how EFs affected community participation experiences. Thematic analysis was used.
RESULTS: Regression results showed significant associations between PFs and five community participation outcomes (R2 = 13% - 48%, p < 0.05), and EFs explained an additional 11% variation in satisfaction with participation and 11% in GPS-derived measures of activity space, after adjusting for PFs (ΔR² = 0.11, p < 0.05). Among individual EFs, after accounting for PFs, perceived financial resources was associated with ability to participate (B = 1.46, p = 0.018), and satisfaction with participation (B = 3.12, p < 0.001). Social support (B = -1.05, p = 0.022) and neighborhood safety (B = 1.3, p = 0.007) were associated with activity space. Qualitative findings revealed that mobility aid users experienced increased challenges in the built environment, and non-users reported more concerns about the attitudinal environment. They also described how environmental support enabled participation despite functional declines. Acceptance and adaptation were useful strategies, but participants called for improvements in the built environment, information access, MS specialty care, and public attitudes towards disability.
CONCLUSION: Community participation among PwMS is influenced by both PFs and EFs. Statistically, EFs uniquely affected participation satisfaction and activity space, while qualitative findings revealed major barriers and highlighted needs for improvement in physical, social, and attitudinal environments.

Qualitative findings revealed that mobility aid users experienced increased challenges in the built environment, and non-users reported more concerns about the attitudinal environment. They also described how environmental support enabled participation despite functional declines. Acceptance and adaptation were useful strategies, but participants called for improvements in the built environment, information access, MS specialty care, and public attitudes towards disability.
CONCLUSION: Community participation among PwMS is influenced by both PFs and EFs. Statistically, EFs uniquely affected participation satisfaction and activity space, while qualitative findings revealed major barriers and highlighted needs for improvement in physical, social, and attitudinal environments.},

Rest Assured: The Association of Structural, Functional Support, and Loneliness With Subjective Sleep Health.
Journal of sleep research [Epub ahead of print].
Sleep is increasingly understood as a socially embedded phenomenon. This study examined how structural and functional aspects of social support, as well as loneliness, relate to sleep health in a German sample of middle-aged adults (N = 5388). Drawing on the socio-ecological model of sleep health, we assessed the contributions of social support dimensions while accounting for age, sex, and socioeconomic status, as well as psychological covariates. The results of the binary logistic regression showed that functional support (ESSI), friend network size (LSNS6), and loneliness (CES-D item 14) significantly (p < 0.001) predicted sleep health (PSQI), while family network size did not. The portion of explained variance was small (4%-5%). Results remained robust after adjusting for age, sex, and socioeconomic status, but no longer when including psychological covariates (GAD-7, SWLS, CES-D), in which case only the friend network size remained significant (p = 0.019). Women were significantly more affected by poor sleep health than men, and with higher socioeconomic status, fewer people reported suffering from poor sleep (all: p < 0.001). Additional subgroup analysis revealed higher age as a risk factor for worse sleep health in women only, while the friend network was only relevant in men. Our findings highlight the importance of distinguishing between structural and functional dimensions of social support in sleep health research and interventions, and suggest a potential sex-by-age interaction. Future research should promote equity by including diverse populations and longitudinally examine how social support, especially friend networks, affects sleep across genders, ages, and contexts.

Predicting suicidal and self-harm ideation using ecological momentary assessment: deep learning analysis in a general population sample.
BMC psychiatry, 26(1):192.
BACKGROUND: Suicidal and self-harm ideation are major risk factors for suicide but are often difficult to detect, particularly in non-clinical populations. Ecological Momentary Assessment (EMA) offers a real-time, low-burden method for monitoring psychological states, yet its predictive value outside clinical settings remains unclear.
OBJECTIVE: To evaluate whether brief, indirect daily EMA data collected via a smartphone app can predict suicidal and self-harm ideation two weeks later in a general population sample.
METHODS: A total of 499 adults in Korea completed 28 days of EMA using the BIG4 + app, reporting on seven daily items related to mood, sleep, appetite, concentration, fatigue, and loneliness. Suicidal and self-harm ideation were assessed using the CESD-R at baseline, 2 weeks, and 4 weeks. A recurrent neural network with Long Short-Term Memory (LSTM) architecture was trained on two-week EMA sequences, using 10-fold cross-validation.
RESULTS: The combined model using EMA and baseline data achieved an AUC of 0.873 for suicidal ideation and 0.821 for self-harm ideation. Predictive accuracy exceeded an AUC of 0.75 by day 6. Participants with ideation consistently showed lower scores on all EMA items. The study achieved a 94% compliance rate.
CONCLUSIONS: Brief, indirect EMA data can predict near-term suicidal and self-harm ideation in a general population. These findings support the feasibility of smartphone-based EMA as a scalable and non-intrusive tool for early detection of suicide risk.

An ecological model in support of an ontology of mental functioning.
PLOS mental health, 3(1):e0000407.
Health records contain rich sources of mental health data that can be used to evaluate disability and health care outcomes. However, a lack of behavioral health ontologies focused on daily life activity functioning has impeded development of clinical informatic tools to extract mental functioning information. We aim to present the theoretical foundation and conceptual model upon which the Ecological Mental Functioning Ontology (EMFO) was built to facilitate natural language processing (NLP) to extract mental functioning information in free-text clinical records. Subject matter experts operationally defined mental functioning, and a related theoretical perspective was established. Face validity of a proposed model was obtained using an iterative grounded theory approach. An annotation schema based on the model was constructed and tested using manual annotation and consensus on datasets of real and synthetic clinical notes. An annotation schema, based on the Ecological Model of Mental Functioning (EMMF), was shown to be robust when using NLP methods to identify and extract mental functioning information in real and synthetic behavioral health clinical notes. Mental functioning is a complex phenomenon that is fully conceptualized within an ecological milieu encompassing the dynamic transactive relationship between the person, the nature and demands of activities the person participates in, and the external contextual and environmental factors within which the activities take place. By operationalizing mental functioning, the EMMF provided a conceptual roadmap to develop the EMFO and NLP methods that identify and extract mental functioning activity information in clinical records.

Modulation statistics of natural soundscapesa).
The Journal of the Acoustical Society of America, 159(2):1263-1289.
Modulation statistics of "natural soundscapes" were estimated by calculating the modulation power spectrum (MPS) of a database of acoustic samples recorded in nine pristine terrestrial habitats for four moments of the day and two contrasting periods, differing in precipitation level. In particular, a set of statistics estimating low-pass quality, starriness, separability, asymmetry, modulation depth, and 1/ftα temporal-modulation power-law relationships were calculated from the MPS of the samples and related to geographical, meteorological factors and diel variations. MPS were found to be generally low-pass in shape in the modulation domain with most of their modulation power restricted to low temporal (<10-20 Hz) and spectral modulations (<0.5-1 cycle/kHz). Modulation statistics were distinguished between habitats irrespective of moment of the day and precipitation period with a greater role of modulation depth and starriness. Separability and starriness were found to be related to the global biodiversity decrease from tropical to polar regions, suggesting that the lack of joint high spectral and fast temporal modulations and MPS complexity are important features that may characterise "biophony," the collective sound produced by animals in a given habitat. These findings may help guide research on monitoring auditory behaviours and underlying mechanisms expected to exploit regularities of natural scenes.

Human-centered AI to promote youth mental health: a serendipitous natural experiment enabled by a digital health platform.
PeerJ, 14:e20772.
BACKGROUND: Health systems are struggling to deliver timely preventive care, particularly for marginalized populations, necessitating integration across health, education, and social services. For Indigenous youth in rural communities, fragmented services, isolation, and limited culturally safe options worsen mental health disparities. Interactive technologies, particularly human-centered artificial intelligence (AI)-enabled digital health platforms grounded in human-computer interaction (HCI), can enable remote interaction with citizens and decision-makers. This study investigated a serendipitous natural experiment to assess varying levels of platform nudging on Indigenous youth compliance in a longitudinal intervention.
METHOD: This study emerged from the final year of a 5-year initiative embedding a culturally appropriate digital health intervention into school curricula in rural Indigenous communities. While the broader aim was to assess long-term mental health outcomes, an unexpected system disruption assessment of digital nudging on compliance. The platform featured two interfaces: a citizen-facing mobile app for ecological assessments and nudges, and a scientist dashboard for monitoring engagement and triggering nudges. Youth received three nudges: (1) daily system-triggered reminders to complete assessments, (2) weekly non-personalized messages (e.g., land-based activity reminders), and (3) weekly personalized "Best Picture" messages showcasing youth-submitted images. The disruption created four phases: Phase 1 included all nudges; Phase 2 removed non-personalized and personalized nudges; Phase 3 reintroduced them; Phase 4 removed only personalized nudges. Data were analyzed using one-way analysis of variance (ANOVA) with Tukey post hoc tests in R 4.4.2.
RESULTS: Compliance, measured by completed mobile ecological prospective assessments (mEPAs), varied significantly across most phases. Comprehensive nudging (Phase 1) yielded the highest completion rates and fastest response times, which declined following the removal of personalized scientist-triggered nudges. Loss of personalized scientist-triggered nudges had the most substantial impact on compliance.
CONCLUSIONS: Consistent system-triggered reminders and personalized "Best Picture" nudges were most effective in sustaining compliance. Findings highlight the importance of integrating personalized, two-way communication features into digital health platforms to strengthen engagement in rural Indigenous communities. By enabling real-time interaction between youth and scientists, the platform supported integration across health, education, and research sectors. Its human-controlled backend and customizable citizen-facing interface reflect principles of human-centered AI, emphasizing trust and autonomy. This approach offers a scalable model for ethical, effective digital interventions that balance technological precision and participant agency.

Longitudinal Changes in Nasal and Oral Microbiome and Antimicrobial Resistance Gene Profiles in Response to Human Fecal Microbiota Transplantation.
bioRxiv : the preprint server for biology.
The gut-lung axis describes interactions between intestinal and respiratory mucosal systems through microbial, metabolic, and immune pathways, but the systemic impact of gut-targeted therapies on upper respiratory tract (URT) communities remains underexplored. We conducted a longitudinal study in adult patients undergoing fecal microbiota transplantation (FMT) for recurrent Clostridioides difficile infection (CDI) alongside healthy controls. Fecal, nasal, and oral samples were collected at baseline (Day 0) and on Days 14 and 56 following FMT. Shotgun metagenomic sequencing was performed to quantify microbial diversity, taxonomic composition, and the abundance of antimicrobial resistance genes (ARGs). FMT was associated with increased gut diversity and decreased levels of key intestinal taxa commonly considered pathobionts, including Klebsiella spp., Escherichia spp., Shigella spp., and Klebsiella pneumoniae. At the phylum level, fecal Bacteroidota increased, while Mucoromycota decreased following treatment. Post-FMT nasal microbiome changes included reduced richness and diversity, expansion of Moraxella, and decreases in taxa linked with respiratory colonization, including Staphylococcus aureus and Streptococcus pneumoniae. By Day 56, nasal communities partially recovered toward healthy profiles. Baseline nasal ARG abundance decreased following FMT, particularly among β-lactam, aminoglycoside, and fluoroquinolone resistance genes, and remained comparable to healthy controls by Day 56. In contrast, the oral microbiome and oral resistome remained largely stable, with only minor fluctuations, and no consistent increases in respiratory pathobiont-associated taxa. In summary, FMT was associated with broader effects beyond the gut, including changes in the URT microbial ecology and antimicrobial resistance profiles. Together, these findings are consistent evidence of gut-lung microbial interactions, linking intestinal dynamics with respiratory microbial composition and antimicrobial resistance patterns.

Negative emotional inflexibility underlies biological inflexibility: An ecological momentary assessment and passive digital sensing study.
Journal of affective disorders, 402:121352.
Emotional flexibility, thought to reflect the ability to adapt to internal and external environmental stimuli, is associated with psychological well-being. Emotional inertia and network density, defined as stability and interconnectedness, respectively, of emotions, are aspects of emotion dynamics that represent low emotional flexibility. Studies examining biological substrates of emotional persistence are largely limited to emotional inertia and non-depressed samples. Heart-rate variability (HRV) is a transdiagnostic biomarker for psychopathology thought to be associated with emotional flexibility. This study examined whether emotional inertia and network density were associated with HRV in adults with moderate-to-severe depression (N = 315). Participants completed three 8-day epochs of ecological momentary assessment (EMA) five times daily. Smartwatches measured HRV throughout the study. Emotional inertia and idiographic networks were calculated separately for EMA-rated negative and positive affect. Bayesian dynamic structural equation models with noninformative prior distributions examined the association between emotional inertia and HRV; hierarchical linear modeling examined associations between network density and HRV. Both daytime and bedrest HRV were inversely associated with contemporaneous network density of negative emotions. HRV was not associated with inertia, positive network density, or average EMA-reported affect, though it was associated with age, antidepressant medication, and physical exercise. This was the first study to examine HRV in relation to these emotion dynamics in a depressed sample. The results suggest that experiencing a variety of negative emotions within a short period of time may be associated with underlying biological inflexibility. Future studies should examine the directionality and mechanisms behind this effect and explore potential clinical interventions.

Closing the loop: A systematic review of artificial intelligence in circular e-waste management.
Waste management (New York, N.Y.), 214:115392 pii:S0956-053X(26)00062-0 [Epub ahead of print].
The proliferation of technological advancements, knitted with volatile consumption patterns and poor end-of-life management of discarded electronics, is currently outpacing sustainability transitions, putting increasing strain on finite material resources and heightening ecological vulnerability. This, in turn, has made electronic waste a stealth contributor to climate change with adverse impacts on the environment, economy, and society at large. This reality underscores the urgent need for a strategic shift from linear waste-disposal methods to circular pathways, where Artificial Intelligence (AI) can build more sustainable feedback loops. At the nexus of AI and circular e-waste management, this study systematically reviews 147 articles from 2019 to October 2025. The analysis reveals a steady increase in AI adoption, particularly in deep learning-based detection and classification applications. To structure the evidence from the literature, a six-tier taxonomy is proposed, encompassing AI methods, lifecycle stages, data, waste types, limitations, challenges, and future pathways and opportunities. Beyond technical interventions, systemic and operational barriers that demand strategic levers to address regulatory ambiguities, legislative gaps, managerial inefficiencies, and logistical fragmentation are elucidated. These challenges underpin data availability and generalizability, as well as the lack of standardization, interoperability gaps, and barriers to the ethical and regulatory adoption of AI. In practice, these constraints limit the development of uncertainty-aware electronic waste systems capable of functioning under realistic operational dynamics. To this end, the paper reframes AI-based systems from terminal sinks to regenerative loops, aligning technological progress with sustainable electronic waste management.

Micro/nanoplastic-mediated gut dysbiosis and its impact on cardiac and neuroimmune function in zebrafish model: A multi-omics approach.
The Science of the total environment, 1017:181443.
The pervasive distribution of micro- and nanoplastics (M/NPs) across ecosystems necessitates a mechanistic investigation into their toxicological consequences. Chronic exposure to M/NPs through combined intestinal uptake and branchial contact in aquatic animals disrupts epithelial barrier integrity, alters gastric secretions and luminal pH, and induces microbial dysbiosis, evidenced by the depletion of commensal taxa and expansion of pathogenic strains. These local perturbations trigger systemic sequelae, including neurotoxicity and cardiotoxicity. Consequences on cross-species analyses demonstrate translational concordance, as human studies similarly link M/NP bioaccumulation with inflammatory bowel disease, cognitive decline, and cardiovascular dysfunction. Integrative multi-omics approaches, encompassing transcriptomic, metabolomic, and microbiome analyses, have begun to elucidate the molecular cascades underpinning M/NP toxicity, providing high-resolution insights into host-microbe-environment interactions. Notwithstanding these advances, critical gaps remain in chronic exposure modelling, capturing particle heterogeneity, and ensuring ecological realism. In this context, zebrafish (Danio rerio) provide a uniquely tractable system for gnotobiotic rearing, microbial transplantation, and live imaging, thereby enabling causal inference and functional validation in real-time. Collectively, this review establishes zebrafish as a pivotal model for elucidating M/NP-induced gut dysbiosis, neurotoxicity, and cardiotoxicity. Multi-omics analyses and translational evidence reveal systemic inflammation, immune-metabolic disruptions, and mechanistic links to human health, providing a foundation for targeted research, regulatory frameworks, and interventions to mitigate environmental M/NP exposure.

WABAD: A world annotated bird acoustic dataset for passive acoustic monitoring.
Ecology, 107(2):e70317.
Under the current global biodiversity crisis, there is a need for automated and noninvasive monitoring techniques that can gather large amounts of data cost-effectively at various ecological scales, from local to large spatial scales. These data can then be analyzed to inform stakeholders and decision-makers. One such technique is passive acoustic monitoring, which is commonly coupled with automatic identification of animal species based on their sound. Automated sound analyses usually require the training of sound detection and identification algorithms. These algorithms are based on annotated acoustic datasets which mark the occurrence of sounds of species inside sound recordings. However, compiling large annotated acoustic datasets is time-consuming and requires experts, and therefore, they normally cover reduced spatial, temporal, and taxonomic scales. This data paper presents WABAD, the World Annotated Bird Acoustic Dataset for passive acoustic monitoring. WABAD is designed to provide the public, the research community, and conservation managers with a novel and globally representative annotated acoustic dataset. This database includes 5047 min of audio files annotated to species-level by local experts with the start and end time and the upper and lower frequencies of each identified bird vocalization in the recordings. The database has a wide taxonomic and spatial coverage, including information on 91,931 vocalizations from 1192 bird species recorded at 72 recording sites in 29 recording locations (mainly countries) and distributed across 13 biomes. WABAD can be used, for example, for developing and/or validating automatic species detection algorithms, answering ecological questions, such as assessing geographical variations on bird vocalizations, or comparing acoustic diversity indices with species-based diversity indices. The dataset is published under a Creative Commons Attribution 4.0 International license that permits redistribution and reuse on the condition that the original work is properly credited.

Simulation and optimization of multiple permeable reactive barriers (multi-PRBs) for acid mine drainage (AMD) based on machine learning.
Environmental geochemistry and health, 48(3):143.
Multiple permeable reactive barriers (multi-PRBs) are an effective in-situ technology for acid mine drainage (AMD) treatment. However, their practical implementation is hindered by unclear mechanisms and a lack of decision models. In this study, a coupled processes numerical model was developed to simulate the synergistic removal of TFe and SO42[-] through multi-PRBs with the optimized sequence of limestone, followed by biochar and then D201 resin. Machine learning integrated with the Non-dominated Sorting Genetic Algorithm (ML-NSGAII) was proposed for optimization, in which a Backpropagation Neural Network (BPNN) served as a highly accurate surrogate model (R[2] > 0.99) to predict system performance, reducing the computational load by 99.7% compared to conventional methods. Spearman correlation analysis and SHAP model interpretation revealed hydraulic load and filler size as the most influential parameters. Application of the TOPSIS-entropy weight method to the Pareto-optimal solution set yielded a final design that significantly enhanced system service life and treatment capacity while reducing costs. This research provides a practical and computationally efficient strategy for designing multi-PRBs for AMD treatment.

Use of metabarcoding detects the rapid onset of cultivation bias in the culture-based profiling of marine sediment bacterial communities.
Letters in applied microbiology pii:8466406 [Epub ahead of print].
When cultivation-based microbiology is used to isolate strains from environmental samples, the cultured populations may not represent ecologically relevant taxa in the source community. To address this, we employed pre-cultivation metabarcoding to establish a baseline community profile and detect cultivation bias. Using time-resolved cultivation of marine sediment bacteria, we demonstrated the need for initial community characterization. Sediment-derived microbiomes were cultured in Marine Broth 2216 and analyzed using 16S rRNA gene metabarcoding at 0, 6, 12, 18, and 24 h. A rapid 10-fold reduction in alpha diversity was observed within the 6 h (from 1029 amplicon sequence variants to 34-106), with the genus Vibrio reaching near-complete dominance (>95%) from 18 to 24 h, while environmentally dominant taxa such as Acinetobacter were quickly excluded. This dramatic shift illustrates that, without baseline characterization, cultivation-induced artifacts cannot be clearly distinguished from ecologically meaningful patterns. Fast-growing generalists can quickly outcompete ecologically significant taxa, distorting isolation outcomes and hindering the recovery of functionally important microorganisms. We show that metabarcoding at 0 h can identify cultivation biases, help interpret isolation results, and suggest targeted strategies for recovering ecologically relevant taxa. This integrated approach facilitates more accurate recovery and analysis of functionally significant microbial diversity.

Computational pipeline reveals nature's untapped reservoir of halogenating enzymes.
bioRxiv : the preprint server for biology.
Microbial halogenated natural products (hNPs) hold ecological, agricultural, and biomedical relevance. The hNP-producing potential of the organism can be assessed by the precise prediction of biosynthetic enzymes, yet the detailed annotations of halogenases are often missing from genomic and metagenomic data. We created a manually curated database (https://halogenases.secondarymetabolites.org/) containing information on the halide-specificity, role, and position of verified catalytic residues and results of the mutagenesis studies of more than 120 experimentally validated or in silico inferred halogenases. The collection of experimental data supports a computational pipeline that allows the family-, substrate-, and halide-scope-level annotation of halogenating enzymes by relying on catalytic residues, conserved motifs, and profile Hidden Markov Models (pHMMs). Our analysis with sequence similarity networks (SSNs) highlighted several underexplored clusters in the UniRef50 database. Such finding was a halogenase from Rhodopirellula baltica (RhobaVHPO) previously labelled as a hypothetical chloroperoxidase, which clustered apart from the known chloroperoxidases and bromoperoxidases, but accepted chloride and preferred bromide. Our database and workflow provide extensive and scalable solutions for the systematic and precise annotation of halogenating enzymes in genomic and metagenomic data. The in-depth categorization of halogenases will improve the chemical structure prediction of microbial hNPs, supporting ecological assessments and natural product discovery.

Diverging contaminant profiles and prokaryotic assemblages in Arctic and Antarctic lake sediments.
Frontiers in microbiology, 16:1722478.
INTRODUCTION: Persistent organic pollutants (POPs) and trace metals are increasingly recognized as critical drivers of ecological change in polar environments. However, their combined impact on sediment microbial communities remains largely unexplored.
METHODS: We analyzed sediments from 12 high-latitude lakes and ponds, five from the Arctic (Svalbard) and seven from the Antarctic (South Shetland Islands/Deception Island), to examine contaminant profiles (polychlorinated biphenyls [PCBs] and trace metals) and prokaryotic community structure using 16S rRNA gene amplicon sequencing. Finally, we assessed the associations between the identified communities and detected pollutants, and compared these associations across lakes and sites.
RESULTS: The results revealed distinct chemical signatures between poles: Arctic sediments were mainly contaminated by polycyclic aromatic hydrocarbons (∑PAHs, 18.5-685.7 ppb; phenanthrene was the most abundant), whereas Antarctic sediments showed relatively higher concentrations of chlorobenzenes (∑CBs, 1.9-3.6 ppb) and polychlorinated biphenyls (∑PCBs, 0.9-1.4 ppb), with 2-methylnaphthalene as the most abundant PAH. Manganese was the most abundant metal in both regions, reaching 760 ppm in the Arctic, while elevated arsenic and lead characterized specific Antarctic sites. Amplicon sequencing identified five dominant phyla (i.e., Actinobacteriota, Bacteroidota, Alpha- and Gammaproteobacteria, and Desulfobacterota) with significant compositional shifts between poles.
DISCUSSION: Notably, the distinct contaminant signatures between regions appeared to be associated with shifts in microbial community composition, suggesting that both the type and intensity of POP and metal exposure may influence bacterial diversity and ecological functions in polar lake sediments. These findings provide a robust baseline for Arctic-Antarctic comparisons, positioning polar lakes as sensitive sentinels of contaminant-driven ecological change. They also underscore the urgent need for functional studies and long-term monitoring to evaluate ecosystem resilience under accelerating climate change.

Global multi-ancestry genome-wide analyses identify genes and biological pathways associated with thyroid cancer and benign thyroid diseases.
Nature genetics, 58(2):307-316.
Thyroid diseases are common and highly heritable. We performed a meta-analysis of genome-wide association studies from 19 biobanks for five thyroid diseases: thyroid cancer (ThC), benign nodular goiter, Graves' disease, lymphocytic thyroiditis and primary hypothyroidism. We analyzed genetic association data from ~2.9 million genomes and identified 313 known and 570 new independent loci linked to thyroid diseases. We discovered genetic correlations between ThC, benign nodular goiter and autoimmune thyroid diseases (rg = 0.16-0.97). Telomere maintenance genes contributed to benign and malignant thyroid nodular disease risk, whereas cell cycle, DNA repair and damage response genes were associated with ThC. We propose a paradigm that explains genetic predisposition to benign and malignant thyroid nodules. We found polygenic risk score associations with ThC risk of structural disease recurrence, tumor size, multifocality, lymph node metastases and extranodal extension. Polygenic risk scores identified individuals with aggressive ThC in a biobank, creating an opportunity for genetically informed population screening.

abstract = {Thyroid diseases are common and highly heritable. We performed a meta-analysis of genome-wide association studies from 19 biobanks for five thyroid diseases: thyroid cancer (ThC), benign nodular goiter, Graves' disease, lymphocytic thyroiditis and primary hypothyroidism. We analyzed genetic association data from ~2.9 million genomes and identified 313 known and 570 new independent loci linked to thyroid diseases. We discovered genetic correlations between ThC, benign nodular goiter and autoimmune thyroid diseases (rg = 0.16-0.97). Telomere maintenance genes contributed to benign and malignant thyroid nodular disease risk, whereas cell cycle, DNA repair and damage response genes were associated with ThC. We propose a paradigm that explains genetic predisposition to benign and malignant thyroid nodules. We found polygenic risk score associations with ThC risk of structural disease recurrence, tumor size, multifocality, lymph node metastases and extranodal extension. Polygenic risk scores identified individuals with aggressive ThC in a biobank, creating an opportunity for genetically informed population screening.},

PFOA and co-exposure with PFOS induce AMPK-dependent hypoglycemia in mice: integrated evidence from physiology, multi-omics, and molecular docking.
Environment international, 208:110076.
Per- and polyfluoroalkyl substances, notably perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS), are persistent environmental contaminants with increasing evidence of metabolic toxicity. However, their effects on glucose homeostasis and the underlying mechanisms remain unclear. In this study, we investigated the metabolic consequences of PFOA, PFOS and co-exposure in male C57BL/6 mice for 28 days. Physiological indicators, including fasting blood glucose and hepatic glycogen, were evaluated, followed by transcriptomic, metabolomic, and molecular docking analyses. We found that PFOA and PFOS co-exposure significantly induced hypoglycemia and reduced hepatic glycogen content. Transcriptomic and metabolomic profiling revealed enriched pathways related to glucose metabolism, with the AMPK signaling pathway identified as a central mediator. Notably, PFOA and co-exposure upregulated glycolytic and fatty acid oxidation genes, while suppressing glycogen synthesis regulators. Molecular docking further indicated that both PFOA and PFOS could bind to adiponectin receptors (AdipoR1/2), potentially disrupting normal receptor-mediated AMPK activation. Together, these findings establish an AdipoR1/2-AMPK-mediated mechanism for PFAS-induced glucose metabolic disruption, particularly under PFOA or co-exposure. We provide the integrated physiological and mechanistic evidence linking PFAS exposure to AMPK-dependent hypoglycemia, highlighting the need for metabolic health risk assessments of PFAS mixtures in the environment.

Transcriptomic Correlation Identifies Cell Model Representatives for MYCN-Amplified Pediatric Neuroblastoma, Downstream Impact of Model Choice on Functional Interpretation, and Potential Drug Repositioning Candidates.
Omics : a journal of integrative biology [Epub ahead of print].
Neuroblastoma (NB) is the most common extracranial solid malignancy of children, and MYCN amplification defines a high-risk subtype with poor outcomes. Although widely used in preclinical drug discovery, NB cell lines are often selected based on availability rather than the molecular characteristics of patient-derived tumors, leading to a critical translational gap between experimental outcomes and clinical relevance. To address this, we developed a rank-based transcriptomic correlation framework to assess the concordance between patient-derived tumors (n = 642; combined from the SEQC/MAQC-III and TARGET cohorts) and publicly available NB cell lines (n = 39). This system-level analysis enabled the identification of cell model representatives (CMRs) that closely recapitulate the gene expression landscapes of clinical tumors. COG-N-557, SMS-KAN, and NB-SD emerged as the top CMRs for MYCN-amplified tumors, whereas COG-N-549, FELIX, and SK-N-SH were identified for MYCN-nonamplified tumors. Pathway enrichment analyses indicated that MYCN-amplified CMRs retain key transcriptional programs involved in neuronal development and tumor proliferation, supporting their biological relevance. Leveraging these models, we integrated pharmacogenomic connectivity mapping and drug-gene network analyses to uncover kinase inhibitors and epigenetic modulators as promising therapeutic candidates capable of targeting MYCN-driven transcriptional programs, despite MYCN being an undruggable oncogene. In conclusion, this study addresses a fundamental systems biology and translational research gap by establishing a data-driven framework for selecting NB cell lines that accurately reflect patient-derived tumor biology with direct implications for prioritizing therapeutically relevant drug candidates. Future studies should prioritize the top CMRs as in vitro models to enhance translational relevance and accelerate precision drug discovery in high-risk pediatric NB.

An Ecological Definition and Objective Threshold for Differentiating Small Fragments.
Ecology and evolution, 16(2):e73054.
In an increasingly fragmented natural world, understanding how different ecological phenomena vary with patch size has many motivations. Examples include the assembly of biodiversity, ecosystem service provision and the suitability of fragments for habitat specialist species. A common approach to such questions divides fragments into small and large size classes for separate analysis. However, lack of an objective definition and means to differentiate 'small' from 'large' patches limits our ability to compare findings across studies, arguably impeding progress toward any unified views. Because larger and smaller fragments tend, on average, to respectively over-represent narrow- and wide-range species, an 'area for unbiased species representation' (AUSR) can be defined at some intermediate fragment size predicted to contain species at incidence frequencies approximating that of the overall landscape. A central tendency for AUSR has previously been estimated for patchy habitats (islands, habitat islands and fragments), providing a benchmark to compare this threshold of small fragment size between studies. However, if AUSR can be readily determined within individual study systems, it would also provide an objective threshold to separate small and large fragments under the AUSR definition. Here we assess this potential for 138 published datasets from various fragmented landscapes using an index comparing species incidence frequencies in each fragment with that of the overall landscape. Regressing this index on fragment area yielded an estimate for AUSR in over 90% of cases, suggesting broad applicability as an objective way to separate fragments into two size classes. Regression slopes provide further information on the relative representation of narrow- vs. wide-range species, with ~80% being numerically consistent with the overall negative trend. Requiring only the same data as the island species-area relationship, AUSR can provide useful insights on the relative importance of narrow- vs. wide-ranging species for studies of patch-size dependence in ecological phenomena.

Multi-omics and palynology of selected Philippine forest honey.
Scientific reports, 16(1):5359.
The Sierra Madre Mountains, which happen to be the longest mountain range in the Philippines, is home to lush floral and faunal species as well as forest-based indigenous communities actively involved in preserving local biodiversity. With active reforestation efforts ongoing for decades, the locals are further encouraged to continue their long-standing practice of honey gathering as a form of cultural manifestation and as an important source of livelihood. To further inspire ongoing conservation efforts, we aim to show that the small molecule diversity in Sierra Madre forest honey reflects the local floral composition and is reflective of the positive impact of previous reforestation initiatives. In order to do this, liquid chromatography-mass spectrometry (LC-MS) based metabolomics was used to profile and compare metabolite diversity in honey produced by Apis cerana, Apis breviligula Maa. and Tetragonula biroi (Friese) honey from Palaui Island and Laiban in Northern and Southern Sierra Madre, respectively. Surprisingly, the Philippine National Tree and unfortunately endangered Pterocarpus indicus Willd (loc. Narra) proved to be important, especially in Palaui Island where honey from A. cerana is close to being monofloral. Aside from P. indicus and its small molecule marker hypaphorine, caffeine was detected in Palaui honey beautifully reflecting the way of life of native Agtas who manage a small coffee plantation. The abundance of caffeine, however, is higher in stingless honey samples from Tanay, Rizal where Coffea trees have been extensively included in restoration activities over the past few decades. Our results imply the possibility of using honey as an ecological monitoring tool while generating baseline chemical information that reflects the state of Philippine forests. Furthermore, the identification of unique chemical components in forest honey can be further used in programs that assist indigenous communities in safeguarding the ownership and origin of forest honey sources.

Protocol for Personalised Prediction of Persistent Postsurgical Pain.
BMJ open, 16(2):e107055.
INTRODUCTION: Persistent postsurgical pain (PPSP) affects up to 15% of patients after major surgery, impairing physical function, quality of life and increasing risk for long-term opioid use. Current PPSP prediction models rely on static or retrospective data and fail to incorporate dynamic perioperative factors. The Personalised Prediction of Persistent Postsurgical Pain (P5) study aims to develop individualised, multimodal prediction models by integrating preoperative behavioural, psychophysical and neurocognitive assessments and high-frequency symptom monitoring.
METHODS AND ANALYSIS: P5 is a prospective, single-centre cohort study enrolling 2500 adults aged 18-75 undergoing major surgery at a tertiary academic hospital. Participants complete baseline surveys, cognitive testing and quantitative sensory testing preoperatively. Ecological momentary assessments (EMAs) are collected via smartphone three times per day through 30 days postoperatively, capturing pain, mood, catastrophising and medication use. Participants are assessed on postoperative day 1 and complete online surveys at 3 and 6 months, evaluating pain persistence, interference, neuropathic symptoms and related outcomes. Clinical and perioperative data are extracted from the electronic health record. The primary outcome is PPSP at 3 months. Predictive models will be developed using supervised machine learning and dynamic structural equation modelling to extract latent features from EMA data. Model performance will be assessed using area under the receiver operating characteristic curve, area under the precision-recall curve and SHapley Additive exPlanations for interpretability.
ETHICS AND DISSEMINATION: This study has received ethics approval from the Washington University School of Medicine Institutional Review Board #202101123. Informed consent is required. Results will be submitted for publication in peer-reviewed journals and presented at research conferences.

High-concentration polyethylene and polystyrene microplastics co-exposure shorten insect lifespan and impose ecological risk: Multi-omics evidence from Drosophila melanogaster.
Comparative biochemistry and physiology. Toxicology & pharmacology : CBP, 303:110474.
Microplastics (MPs) are pervasive environmental pollutants, accumulating in ecosystems and posing a long-term exposure risk to both the entire ecosystem and human health. However, the combined impact of such high doses on insect longevity and the consequent ecological consequences remain understudied. Here we used Drosophila melanogaster as a model to quantify lifespan shortening under environmentally realistic and extreme concentrations of Polyethylene (PE) and Polystyrene (PS) co-exposures and to unravel the molecular bases of the observed toxicity. Furthermore, we delved into the underlying mechanism through metabolomics and transcriptomics analysis. Our results demonstrated PE and PS MPs co-exposure with greatly high concentrations significantly reduced the lifespan of Drosophila and influenced age-related phenotypes such as climbing ability, intestinal barrier and hunger resistance. We found that differential metabolites were engaged in various metabolic pathways, including ABC transporters, alanine, aspartate and glutamate metabolism. Differentially expressed genes (DEGs) were closely related to Toll and Imd signaling pathway and Longevity regulating pathway. Gram-level PE and PS co-exposure triggers immune-metabolic crosstalk failure and represents a realistic terrestrial risk factor for insect longevity. Our data highlight the urgent need to include high-dose microplastic mixtures in terrestrial ecotoxicological risk assessments and biodiversity conservation strategies. SYNOPSIS: Co-exposure to PE and PS MPs with high concentrations induces changes in gene expression and metabolites associated with immune system and energy metabolism in Drosophila, thereby affecting their lifespan.

In-Field Ecological Momentary Assessment From Wearable Motion Sensors and Self-Report in a Chronic Low Back Pain Cohort.

BACKGROUND: Chronic low back pain (cLBP) is a prevalent and debilitating condition. Gaining insight into the daily experiences of those with cLBP is crucial for developing effective management. Pain and activity are typically assessed at a single time point and often rely on retrospective self-reports, which can be prone to recall bias and may not reflect the day-to-day variability of these experiences. As a part of the University of Pittsburgh LB[3]P Mechanistic Research Center, this study used ecological momentary assessment (EMA) and wearable devices to collect real-time data in a large cohort of adults with cLBP. The primary aims were to collect and characterize pain and activity profiles of individuals with cLBP.
METHODS: This study enrolled 1007 adults with cLBP who met the National Institutes of Health defined criteria. Over 7 days, participants were assessed in their own environment. EMA was gathered in real-time via a custom mobile app, prompting participants three times daily to provide their perceptions of current pain intensity (0-10), pain interference (0-10), and activity level (very light to vigorous). Time of falling asleep and waking was also reported. Participants wore ActiGraph GT9X devices on their wrist and waist. A custom back sensor was also adhered to the skin over the lumbar (L5) segment. Activity counts, wear time, and step counts were calculated, utilizing algorithms provided by ActiGraph. Sensor data were filtered to include at least 4 days of 10 or more hours each. Activity counts were categorized into sedentary, light, and moderate-to-very-vigorous based on Freedson Adult cutpoints.
RESULTS: Out of 1007 participants, 989 submitted EMA data (58.8 ± 16.5 years old; 40% male and 60% female; mean pain intensity at enrollment of 5.4 (SD 2.1) and a median of 5 (interquartile range [IQR] 3) on a 0-10 scale; mean PROMIS Pain Interference T-score at enrollment of 60.5 (SD 7.5) and a median of 61.2 (IQR 9.6)). The median reported pain intensity level from the EMA was 1 (IQR = 3), while pain interference was 3 (IQR = 3). More than half of the participants reported a median pain intensity of either 0 or 1 (54.0%) and a median pain interference between 0 and 3 (57.4%). Most participants self-reported their activity levels as moderate (36%) or light (33%). Based on pain ratings during each day, most participants had their pain intensity (30%) and pain interference (40%) peaking in the evening. ActiGraph data from 884 wrist-worn and 785 waist-worn devices were analyzed. Wrist data showed a median of 1 765 325 (IQR 796 995) activity counts/day and 9575 (IQR 4228) steps/day. Waist data showed 358 390 (IQR 223 758) activity counts/day and 4114 (IQR 3146) steps/day. The percentage of daily sedentary activity was 47.3% for wrist and 72.8% for waist. The back sensor data from 586 participants showed a median of 340 345 (IQR = 223 399) activity counts/day and a median of 3695 (IQR = 2743) steps/day. The percentage of time spent in daily sedentary activity was 82.6%. Both ActiGraph devices and the back sensor indicated that the majority of the time was spent in sedentary activity level, which is lower than the activity level reported in the EMA.
CONCLUSIONS: Despite having cLBP with self-reported moderate pain levels, participants generally reported periods of relatively low levels of pain intensity and interference in their EMA. In addition, their EMA-reported activity levels differed from the sensor data. Participants self-reported higher levels of activity compared to the activity levels calculated by the wearable sensors. This suggests that participants overestimated their activity levels on EMA, or that the activity level cut-points may need to be re-evaluated for the cLBP population. Additionally, sensors placed on different body locations showed varying activity and step counts. The activity counts calculated from the waist ActiGraph and the back sensor from this cohort were lower than the average activity counts in the US adult population. Further research is needed to better quantify these differences for people with cLBP to develop a more comprehensive understanding of the pain experience.

Displacement threatens local knowledge: plant foraging in a cross-cultural context in the Gomal area, NW Pakistan.
Journal of ethnobiology and ethnomedicine, 22(1):12.
In the context of human displacement, it is essential to study how local knowledge is reshaped, eroded, or transformed. This study sheds light on how wild plant reports are articulated after migration, retained, and kept; the research explores specifically the ethnobotanical knowledge linked to wild food plants of five ethnic communities, namely the Bettani, Ormur, Mehsud, and Miani populations living in the Gomal area of NW Pakistan, of which three are displaced communities. The study aims to record the knowledge of wild food plants and their use among generations in these communities. To better determine the impact of displacement, we have analysed the data along two trajectories: (a) cross-geographically comparing the recorded wild food plant reports with the available published literature in NW Pakistan and (b) conducting a cross-cultural comparison of the local plant knowledge among the considered groups (displaced ones: Mehsud, Ormur, and Powanda; autochthonous: Bettani and Miani) residing in the Gomal area. Via semi-structured interviews with a hundred study participants (twenty for each ethic group), the study revealed the use of 69 wild food taxa, showing a remarkable diversity of food uses, with Ormur and Powanda exhibiting several idiosyncratic reports. The research highlights that displacement may have disrupted potential pathways of knowledge transmission among the Mehsud, Ormur, and Powanda; however, local plant knowledge about their past environment remains part of the collective memory of these communities. Moreover, post-migration exposure to a new ecological system has become a challenge for the newcomers, necessitating adaptation to rearticulate their relationship with nature and plants. The broken paths have a profound impact on plant knowledge transmission to youngsters, as social structures and gatherings have been significantly altered or disrupted; these were the primary means of interaction between youngsters and their elders. The exposure to urbanisation compounds the issue of displacement, and the erosion of knowledge systems has come at the expense of hands-on experiences among the selected groups. Notably, the local plant nomenclature of Ormur is also highly threatened. We advocate incorporating local plant knowledge into local educational curricula, which may be crucial for the sustainability of natural knowledge and have profound impacts on mitigating the effects of socioecological change.

Computational epitope heterogeneity analysis in immunostainings from antibody-dilution series.
Communications biology, 9(1):238.
Antibodies are widely used in life sciences and medical therapy. Broadly applicable methods to determine epitope heterogeneity in immunostaining systems are missing. Here, we present a simple-to-use approach to characterize and quantify antibody binding properties that constitute the staining directly in the system of choice. We determine an epitope heterogeneity on the basis of a computational analysis of antibody-dilution immunofluorescence stainings. This allows us to choose signal-specificity maximizing dilutions and to improve signal quantification. Furthermore, the computational analysis provides approaches to obtain a single-channel antibody multiplexing. Our approach could help improving immunostainings in many laboratories by guiding the choice of antibody dilution, by increasing the possibility of antibody-multiplexing in the same color-channel and by allowing for the analysis of binding targets of multi-specific antibodies.

Unveiling scale effects in human settlement environment suitability through a novel multi-factor weighting approach.
Scientific reports, 16(1):6952.
Rural human settlement environment suitability is a key indicator for guiding land-use planning and promoting sustainable rural revitalization. This study develops a refined framework for evaluating the natural suitability of rural human settlement environments in central Hunan, China, using GIS-based spatial analysis. We propose an enhanced factor-weighting method that integrates normalized information entropy (NIE) and the coefficient of variation (CV) into a Pearson correlation coefficient (PCC)-driven approach, thereby improving the objectivity and sensitivity of weight determination. Comparative experiments demonstrate that this hybrid method captures the relative influence of natural factors more accurately than traditional PCC-based techniques. Results reveal a pronounced scale effect: as the spatial analysis scale decreases, disparities in factor weights become more evident. The spatial distribution of suitability exhibits a distinct east-high, west-low gradient, reflecting strong spatial heterogeneity across the region. Among all factors, terrain relief emerges as the dominant driver of suitability variations. Based on the calculated suitability index, the study delineates five functional zones and formulates corresponding development strategies tailored to local conditions. These findings offer a scientific basis for optimizing rural spatial planning and promoting sustainable development in central Hunan and similar regions. Beyond the case region, the framework provides a transferable approach for evaluating natural suitability in other mountainous rural areas. It also offers practical guidance for policymakers seeking to balance ecological protection with sustainable land-use development.

Cluster dispersal shapes microbial diversity during community assembly.
PLoS computational biology, 22(2):e1013918.
Identifying the drivers of diversity remains a central challenge in microbial ecology. In microbiota, within-community diversity is often linked to host health, which makes it all the more important to understand. Since many communities assemble de novo, microbial dispersal plays a critical role in shaping community structure during the early stages of assembly. While theoretical models typically assume microbes disperse individually, this overlooks cases where microbes disperse in clusters, such as, for example, during host feeding. Here, we investigate how cluster dispersal impacts species richness, between-community dissimilarity, and species abundance in the initial steps of microbial community assembly. We developed a model in which microbes disperse from a pool into communities as clusters and then replicate locally. Using both analytical and numerical approaches, we show that cluster dispersal promotes community homogenization by increasing within-community richness and reducing dissimilarity across communities, even at low dispersal rates. Moreover, it modulates the influence of local selection on microbial community assembly and, consequently, on species abundance. Our results demonstrate that cluster dispersal has distinct effects from simply increasing the dispersal rate. This work reveals new evidence for the role of cluster dispersal in the early dynamics of microbial community assembly.

Analogous environments across the tropics have similar levels of tree species alpha diversity.
National science review, 13(2):nwaf465.
Different regions of the tropics vary in overall tree species diversity, with the tropical Americas exhibiting strikingly higher regional tree species richness than Africa and Southeast Asia. We investigated whether these differences also occur at the local scale and whether the environmental conditions associated with tree species richness are consistent across tropical regions despite highly dissimilar species pools. A spatial random forest model was trained by using a network of 429 1-hectare plots across the tropics, together with 24 environmental variables, to predict plot-level tree α diversity. A combination of climatic, soil and topographical variables explained ∼86% of the variation in richness. Despite differences in regional species pools and the potentially disruptive effects of different geological, climatic and evolutionary histories, the relationship between environmental variables and local-scale tree species richness is closely similar across different continents. Our findings imply a pervasive role of niche-based mechanisms in structuring local tree species richness, regardless of the regional species assemblages. This pantropical convergence in the richness-environment relationship poses a challenge for ecology to explain.

Predictive monitoring, identification, and control of Microcystis blooms in a drinking water source basin: An integrative artificial intelligence and bioinformatics approach.

Harmful algal blooms (HABs) pose serious challenges for drinking water utilities; however, conventional monitoring in drinking water source basins remains largely reactive. To address this, we present an integrative framework that combines artificial intelligence (AI) forecasting with strain-resolved bioinformatic diagnostics to enable proactive monitoring of bloom-causing HAB in drinking water source. The AI model employed environmental input features and was optimized, which achieved high predictive accuracy (up to 0.9 R[2]) with early warning capabilities (1 week lead time). Explainable AI pinpointed organic and nitrogen compounds as top predictors for HAB events. Phylogenomic analysis using short- and long-read sequencing elucidated the population structure, toxicological traits, and ecological adaptation of the bloom-causing Microcystis population (NRERC-214). Field surveys with bioinformatic analysis at a full-scale drinking water treatment plant found complete removal of Microcystis. The relative strengths and weaknesses of the individual units in removing Microcystis in the plant was validated with the phenotypic/genotypic features of Microcystis bioinformatically determined in this study. Overall, this study suggested the integration of a predictive surveillance and diagnosis framework into a source water management scheme, supporting a paradigm shift from reactive post-event management to proactive, risk-based control for drinking water.

A Proposed Unified, Scalable Platform for Integrative Research on Venomous Species.
GigaScience pii:8450176 [Epub ahead of print].
Venomous animal research is hampered by fragmented, specialized, and non-interoperable databases (isolated genomic, proteomic, and ecological data). Despite the immense promise of venomous organisms to yield novel bioactive compounds for pharmacological and evolutionary applications, the informatics landscape for such taxa has remained patchy, lacking macro-scale integration across species. We present VenomsBase, an integrated, modular resource that synthesizes multi-omics data, ecological metadata, and functional annotations for venom-bearing organisms. Following the FAIR guidelines, VenomsBase combines an ontology-driven architecture with big-data cloud workflows for sequence integration, motif clustering, 3D display, and linking ecological metadata. Standardized tools and training modules facilitate worldwide access to resources for both researchers in developed countries and in resource-limited areas. Its plug-and-play design allows for integration of additional analytical modules and extension to other species. One can also examine evolutionary trends and connect venom chemistry to ecological niches. VenomsBase would (i) accelerate the pace of venom discovery, whether for therapeutic purposes or evolutionary significance, by providing validated, cross-referenced data sets and community-driven curation, and (ii) foster an open, just, and innovation-ready venom research ecosystem.

Adaptive Basin Management under Determinate and Indeterminate Sustainability Factors.
Environmental management, 76(3):69.
Adaptive river basin management is uncertain and complex, as it requires assessing the combined effects of climate change and human activities. Conventional strength-weakness-opportunities and threat (SWOT) decision analysis failed to quantify the indeterminacy concerning factors in adaptive management. To address these limitations, this study introduces a hybrid decision-support system that combines interval valued fuzzy hybrid SWOT (IVFH-SWOT) analysis with fuzzy evaluation of resilience metrics (FERM). To demonstrate its effectiveness, the study evaluated 11 strategic options across four aspects of adaptive sustainability: ecological balance, hydrological-geomorphological integrity, socio-economic and energy potential, and catastrophe resilience. The derived strategies were prioritized based on the multi-stakeholder analysis performed on the data gathered about these four aspects. The findings underscore dam operations regulations (score: 0.7561), treatment of wastewater infrastructure (0.7226), and development of hydropower (0.7122) as the most efficacious strategies. These findings illustrate the trade-offs between resilience performance and sustainability under indeterminate conditions. The proposed framework offers a robust, transferable tool for practitioners and policymakers for adaptive sustainable river basin management.

Synthesised database of wild bee and hoverfly records in Europe.
Scientific data, 13(1):227.
Wild bees (Hymenoptera: Anthophila) and hoverflies (Diptera: Syrphidae), the two major groups of insect pollinators, are undergoing alarming declines worldwide, including Europe. The lack of accessible and verified spatial and temporal occurrence records currently challenges efforts to understand and mitigate this decline. Here, we compiled datasets from diverse sources, including taxonomists, national experts, public repositories, museum collections, published literature, verified open-access platforms, and aggregated datasets from previous European projects. The collected data were standardised, cleaned and validated by taxonomists and national experts. This collective effort resulted in two databases comprising more than 4.34 million and 1.04 million records for wild bees and hoverflies, respectively. The databases cover 97% of the European bee fauna (2,083 species out of 2,138 recorded in Europe) and 97% of the European hoverfly fauna (886 species out of 913 recorded in Europe). These standardised databases constitute essential resources for future assessments of status and trends, habitat associations, and other research and conservation initiatives to protect and understand wild pollinators on the European continent.

Engineered internal architecture of core-shell lipid nanoparticles promotes efficient mRNA endosomal release.
Nature communications pii:10.1038/s41467-026-69017-8 [Epub ahead of print].
Messenger RNA (mRNA) therapeutics rely on lipid nanoparticles (LNPs) for delivery, yet inefficient endosomal escape remains a major bottleneck, with only a small fraction of internalized cargo reaching the cytoplasm. Conventional LNPs encapsulate mRNA in amorphous lipid cores, where partial charge neutralization and lack of structural order limit protonation-driven membrane disruption. Here, we present an architectural strategy that engineers LNP internal structure using ionizable lipid-coated gold nanoparticles (IC-AuNPs) as rigid, pH-responsive cores. The Au cores template the formation of radially ordered core-shell architectures that stabilize particles at physiological pH while amplifying charge segregation and curvature stress under acidic endosomal conditions. As a result, Au-LNPs achieve a twofold increase in endosomal escape and ~100-fold greater cytoplasmic mRNA diffusion compared to conventional LNPs. Functionally, Au-LNPs enhance mRNA expression in vitro, increases in vivo protein production up to sevenfold, boost antibody responses to SARS-CoV-2 vaccines, and improve therapeutic efficacy in a triple-negative breast cancer model.

Pantropical moist forests are converging towards a middle leaf longevity.
Nature communications pii:10.1038/s41467-026-68989-x [Epub ahead of print].
Leaf longevity is a fundamental plant trait that largely explains ecosystem functional dynamics in global pantropical moist forests. However, the signs, magnitudes, and mechanisms of the spatiotemporal variations in leaf longevity with ongoing climate change are still lacking. Using both ground measurements and gridded leaf age-dependent leaf area index data, we map the continental-scale variability of annual mean leaf longevity across pantropical moist forests over 2001-2023. We find a biome-dependent and converging trend in leaf longevity under climate change. In Amazon and tropical Asia with long leaf longevity (> ~1.8 years), leaf longevity decreases due to rising temperature and intensified atmospheric dryness. In contrast, an increasing trend is observed in Congo and subtropical Asia where forests have short leaf longevity (<~1.8 years). These responses cause a convergence of pantropical short and long leaf longevity into a middle longevity range, with maximization of plant functional traits, photosynthesis, and species evenness, which are expected to better resist climate variability. Our study provides emerging evidence for large-scale structural and functional adaptions across pantropical moist forests and is helpful for predicting climate-driven risks to ecosystem stability.

Restoration based on cost-benefit optimization: A grasslands pilot study.
Ecological applications : a publication of the Ecological Society of America, 36(1):e70174.
Ecological restoration is essential to meeting global biodiversity conservation goals. Given limited conservation budgets, deciding where to restore habitat is a key challenge for the coming decade. We developed a spatially explicit framework to optimize ecological restoration site selection by integrating land use history, species distributions, and economic costs. The framework includes the following steps: identify potential restoration area based on relevant environmental measures like land use; identify species of interest; calculate restoration benefits by modeling habitat and climate suitability and estimating reduced extinction risk associated with restoring a particular land parcel based on a modified species-area relationship; aggregate benefits across species; and compare to parcel-level land acquisition costs. We applied linear programming to maximize conservation benefit/restoration cost ratios to identify optimized restoration sites. We illustrate this approach using a case study for highly threatened grassland ecosystems in the Great Plains region of Kansas, USA. We selected five grassland animal species (greater prairie chickens [Tympanuchus cupido], lesser prairie chickens [Tympanuchus pallidicinctus], swift fox [Vulpes velox], pronghorn [Antilocapra americana], and regal fritillary [Speyeria idalia]) as indicators of restoration benefit across taxa. For the indicator species that we chose, shortgrass and mixed-grass prairies had the highest conservation benefit to cost ratio. Setting a minimum restoration threshold for each habitat type allowed us to identify high-priority tallgrass prairie sites. Despite increasing interest in ecological restoration, optimizing restoration site selection is challenging because one must consider habitat features that do not currently exist. The modeling approach described here is flexible and can be updated for different ecosystems, species, and conservation priorities. We outline potential alterations that can be made in future analyses, depending on desired restoration goals.

Multi-omics insights into Alizarin red S-induced alterations in redox balance, immune function and metabolism in juvenile silver carp (Hypophthalmichthys molitrix).
Journal of hazardous materials, 504:141270.
Alizarin red S (ARS), a widely used anthraquinone dye in industrial processes, has emerged as a potential environmental contaminant with poorly understood ecotoxicological impacts on aquatic organisms. In this study, juvenile silver carp (Hypophthalmichthys molitrix) were exposed to graded concentrations of ARS (0, 100, 125, and 150 mg/L) for 96 h, revealing clear dose-dependent toxicity characterized by reduced survival and progressive histopathological damage in pelvic fins, opercula, and otoliths. Integrated multi-omics analyses of gill tissues demonstrated that high-dose ARS exposure profoundly disrupts physiological homeostasis. Transcriptomic profiling revealed concentration-dependent dysregulation of genes involved in xenobiotic metabolism, oxidative stress, immune response, and metabolic pathways. Notably, exposure to 150 mg/L ARS significantly perturbed signaling pathways associated with immune dysregulation and cellular stress responses. Metabolomic analysis identified 478 differentially abundant metabolites, with pathway enrichment indicating disruption of lipid and amino acid metabolism, particularly glutathione and arginine metabolism. Integrated transcriptome-metabolome analysis further highlighted coordinated alterations in critical pathways including glutathione metabolism, antigen processing and presentation, phagosome, and cytochrome P450-mediated drug metabolism, suggesting a transition from antioxidant defense to systemic immune and metabolic dysfunction under high-dose exposure. Functionally, the activities of catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px), along with glutathione (GSH) content, peaked at 100 mg/L ARS. Critically, malondialdehyde (MDA) content decreased significantly with increasing ARS concentration, attaining a minimum at 150 mg/L ARS. Collectively, these findings define a critical threshold for toxicological transition, provide crucial insights into the ecological hazards posed by anthraquinone dyes and underscore the necessity for stringent regulatory control of ARS emissions into aquatic ecosystems.

A chemical space model for the exploration of eco-toxicological data.

With over 350,000 chemicals and mixtures currently registered for production and use worldwide, around 83% of authorized chemicals lack adequate toxicity data, leaving the majority of chemicals poorly characterized. International agencies urge scientists to develop screening methods to explore, identify, and predict chemical hazards, supporting the prioritization of chemical risk assessment. Here, Tree Manifold Approximation and Projection (TMAP) were applied, with the aim of reducing the dimensionality of large toxicological dataset, providing the foundations to data imputation methods allowing to get an understanding of chemical modes of action. Specifically, TMAP was implemented using MHFP6 fingerprints and the NORMAN SusDat database, which contains over 100,000 compounds. To ensure that the TMAP layout preserves chemical structural similarity, a quantitative parameter optimization procedure was developed. The defined optimal parameter set allowed us to define the embeddings that preserves the most structural similarity among nearest connected neighbors, with similarity progressively decreasing as the distance between nodes increases. Leveraging this approach, a graph-based spatial imputation function was generated to obtain insights into the potential ecotoxicity mechanisms of data poor chemicals using physicochemical properties and CTD toxicogenomic data. The relevance and meaningfulness of TMAP chemical space was explored for Daphnia magna, Pimephales promelas and Algae. Chemical classes known to be structurally similar were found to be grouped together in the TMAP chemical space, while heterogeneous classes were found to be sparse. Data imputation allowed for the identification of known and potential chemical mechanisms of action. Indeed, acetylcholinesterase and transthyretin were confirmed as major mechanisms of action of organothiophosphate and brominated flame retardant toxicity in Daphnia magna and Pimephales promelas, respectively. Overall, transdisciplinary toxicological databases combined with TMAP, stand out as a computationally efficient and suitable method to explore and analyze large datasets, allowing for the inference of associations between chemical structures and chemical hazard identification and other potential applications of this hypotheses-generating tool.

High-precision tracking of human foragers reveals adaptive social information use in the wild.
Science (New York, N.Y.), 391(6784):eady1055.
Foraging complexity and competitive social challenges are considered key drivers of human cognition. Yet, the decision-making mechanisms that underlie social foraging in the real world remain unknown. Integrating high-precision Global Positioning System (GPS) tracking and video footage from large-scale foraging competitions with cognitive-computational modeling and agent-based simulations, we show how foragers integrate personal, social, and ecological information to guide spatial search and patch-leaving decisions. We show how the social context emerges as a key driver of foraging dynamics. Foragers adaptively rely on social information to locate resources when unsuccessful and extend giving-up times in the presence of others, which results in increased area-restricted search at high social densities. These findings demonstrate the importance of sociality for human foraging decisions and provide a template for harnessing high-resolution tracking data to study real-world cognition.

Artificial intelligence in microplastics domain: Current progress, challenges, and sustainable prospects.
Journal of hazardous materials, 503:141233.
Microplastics (MPs) have emerged as pervasive and persistent global environmental contaminants. However, the current inability to robustly analyze these particles hinders a deeper mechanistic understanding of their environmental behavior and ecological consequences. Artificial Intelligence (AI), with its computational power and data processing capabilities, is revolutionizing the analysis of MPs and transforming methodological paradigms. This critical review summarizes key challenges in the field, including persistent methodological limitations in characterization techniques and the interpretation of environmental behavior. We also critically examine emerging applications of AI in MPs domain. We explore the reliability and generalizability of these AI-driven approaches, highlighting that while data accessibility and computational resources pose core operational challenges, the environmental costs and ethical dilemmas of AI also demand scrutiny. Finally, we envision a paradigm shift towards an eco-conscious AI that harmonizes ecological accountability with computational efficiency. Fostering this transition through interdisciplinary collaboration is crucial for guiding MPs research toward a future that is sustainable across environmental, economic, and social consideration.

Synergistic Plant Biostimulatory Effects of an Inter-Kingdom Interaction: Chlorella sp. and Kocuria rhizophila Algal-Bacterial Co-Culture for Sustainable Crop Production.
Plants (Basel, Switzerland), 15(2):.
Plant biostimulatory effects of the green alga Chlorella sp. MACC-360, the Kocuria rhizophila FSP120 bacterial strain, and the combined inter-kingdom co-culture of the alga and bacterium were investigated using Solanum lycopersicum as a model plant grown under controlled greenhouse conditions. The application of algal-bacterial co-cultures using the soil drench method significantly improved plant growth parameters, vegetative biomass yield, fruit yield, and photosynthetic performance of the tomato plants. The combined treatment resulted in a 43.7% increase in mean fruit yield, while individual applications of K. rhizophila FSP120 and Chlorella sp. MACC-360 enhanced yields by 30.85% and 19.44%, respectively. Although total yield increases did not reach statistical significance due to high intra-group variability, the treatment's efficacy was statistically confirmed through key yield parameters including significantly higher fruit weight and fruit diameter (p < 0.05). The enhanced specific biostimulatory effects of the combined treatment could be at least partly attributed to the increased level of algal extracellular polymeric substances (EPS), which was a specific effect of algal co-cultivation with a Kocuria rhizophila bacterium. Detailed analysis of plant phenotypic alterations, biomass yield, fruit and flowering parameters, as well as microbial community analysis of the rhizosphere, were conducted and compared among the various treatments. Our results indicate that an appropriately chosen combination and application of biostimulatory microbes can significantly enhance crop production, which might contribute to more sustainable agriculture.

Bioinformatic Insights into the Carotenoids' Role in Gut Microbiota Dynamics.
Nutrients, 18(2):.
Background/Objectives: Carotenoids are bioactive pigments with well-established antioxidant and immunomodulatory properties, yet their impact on gut microbiota remains poorly understood from a chemical standpoint. This study explores how carotenoid structure and gastrointestinal stability shape microbial responses combining in vitro fermentation with bioinformatic analyses. Methods: Individual carotenoids (beta (β)-carotene, lutein, lycopene) and combined carotenoids, as well as algal-derived extracts were subjected to 48 h in vitro fermentation, and microbial composition and activity were assessed through sequencing and computational analysis. Results: β-carotene and lycopene promoted acid-tolerant taxa such as Escherichia-Shigella, whereas lutein, due to its higher polarity, supported more transient fluctuations. Mixtures and algal carotenoids exhibited synergistic effects, sustaining beneficial genera including Bifidobacterium and Bacteroides and promoting structured ecological trajectories. Conclusions: These findings provide a chemistry-driven perspective on how carotenoids act as modulators of microbial ecosystems, with direct implications for the formulation of carotenoid-enriched functional foods and dietary interventions.

Ecological and Functional Landscape of the Oral Microbiome: A Multi-Site Analysis of Saliva, Dental Plaque and Tongue Coating.
Microorganisms, 14(1):.
The oral cavity contains several microbial niches, including saliva, dental plaque and tongue coating, each shaped by distinct local environments and host factors. This study compared the ecological and functional characteristics of the microbiomes of these three oral sites within the same individuals and examined host conditions associated with their variation. Saliva, supragingival plaque and tongue coating samples were collected simultaneously from 31 adults without clinical oral lesions. The bacterial 16S rRNA gene (V3-V4 region) was sequenced using the Illumina MiSeq platform, and analyses included α and β diversity, Mantel correlations, differential abundance tests, network analysis and functional prediction. The three sites displayed a clear ecological gradient. Saliva and tongue coating were taxonomically similar but were influenced by different host factors, whereas plaque maintained a distinct, biofilm-like structure with limited systemic influence. Functional divergence was most pronounced on the tongue coating despite its taxonomic similarity to saliva, whereas functional differences between saliva and plaque were modest despite larger taxonomic separation. These findings indicate that microbial composition and function vary independently across oral niches and support the need for multi-site sampling to more accurately characterize oral microbial ecology.

Elevated Blood Pressure and Risk Factors in 19-Year-Olds in Serbia: A Cross-Sectional Study.
Medicina (Kaunas, Lithuania), 62(1):.
Background and Objectives: Hypertension in young adulthood is increasingly recognized as a precursor to future cardiovascular disease. Early identification of modifiable risk factors, such as dietary habits, lifestyle behaviors, and psychological indicators, is critical for prevention. This study aimed to examine the elevated clinic blood pressure and associated factors in 19-year-old individuals in Serbia. Materials and Methods: A cross-sectional study was conducted using data from the 2019 Fourth National Health Survey. A total of 212 participants underwent blood pressure measurement, anthropometric assessment, and completed standardized questionnaires on diet, physical activity, depressive symptoms, and sociodemographic characteristics. Blood pressure was classified according to ESC/ESH guidelines. Associations with elevated blood pressure were assessed using chi-square tests and multivariate logistic regression. Results: Most participants had optimal or normal blood pressure, while 18.9% had elevated blood pressure, including high-normal and Grade I-II hypertension. Elevated blood pressure was more prevalent among males and was associated with depressive symptoms. Nutrition status was significantly associated with elevated blood pressure, and some dietary habits like consumption of pure fruit or vegetable juices and the intake of processed meat products. Other socioeconomic factors, eating habits and physical activity were not significantly correlated. In multivariate logistic regression, elevated arterial blood pressure was significantly associated with consuming pure fruit or vegetable juices less than once per week (OR = 3.239; 95% CI: 1.413-7.427) and with consuming processed meat products several times per week in comparison to the daily consumption (OR = 0.325; 95% CI: 0.130-0.812), while no other variables remained statistically significant. Conclusions: Clinically elevated arterial blood pressure is present in a substantial proportion of 19-year-olds. Early lifestyle interventions targeting nutrition and psychological health may prevent progression to hypertension and reduce long-term cardiovascular risk.

Overwinter Syndrome in Grass Carp (Ctenopharyngodon idellus) Links Enteric Viral Proliferation to Mucosal Disruption via Multiomics Investigation.
Cells, 15(2):.
Overwinter Syndrome (OWS) affects grass carp (Ctenopharyngodon idellus) aquaculture in China, causing high mortality and economic losses under low temperatures. Failure of antibiotic therapies shows limits of the 'low-temperature-pathogen' model and shifts focus to mucosal barrier dysfunction and host-microbiome interactions in OWS. We compared healthy and diseased grass carp collected from the same pond using histopathology, transcriptomics, proteomics, and metagenomics. This integrated approach was used to characterize intestinal structure, microbial composition, and host molecular responses at both taxonomic and functional levels. Results revealed a three-layer barrier failure in OWS fish: the physical barrier was compromised, with structural damage and reduced mucosal index; microbial dysbiosis featured increased richness without changes in diversity or evenness, and expansion of the virobiota, notably uncultured Caudovirales phage; and mucosal immune dysregulation indicated loss of local immune balance. Multi-omics integration identified downregulation of lysosome-related and glycosphingolipid biosynthesis pathways at transcript and protein levels, with disrupted nucleotide metabolism. Overall gut microbial richness, rather than individual taxa abundance, correlated most strongly with host gene changes linked to immunity, metabolism, and epithelial integrity. Although biological replicates were limited by natural outbreak sampling, matched high-depth multi-omics datasets provide exploratory insights into OWS-associated intestinal dysfunction. In summary, OWS entails a cold-triggered breakdown of intestinal barrier integrity and immune homeostasis. This breakdown is driven by a global restructuring of the gut microbiome, which is marked by increased richness, viral expansion, and functional shifts, ultimately resulting in altered host-microbe crosstalk. This ecological perspective informs future mechanistic and applied studies for disease prevention.

Multi-Omics Profiling of the Hepatopancreas of Ridgetail White Prawn Exopalaemon carinicauda Under Sulfate Stress.
International journal of molecular sciences, 27(2):.
With intensifying global climate change and human activities, and with regional topography interactions, soil and water salinization has intensified, posing major ecological and environmental challenges worldwide. Here, we integrated histology, transmission electron microscopy, RNA sequencing (RNA-seq) and data-independent acquisition (DIA)-based proteomics to profile hepatopancreas responses of Exopalaemon carinicauda during acute sulfate stress (≤48 h). Sulfate exposure disrupted tubular architecture and organelle integrity, consistent with early cellular injury. Multi-omics analyses revealed metabolic reprogramming marked by suppressed glycolysis (e.g., HK2, ENO) and enhanced oxidative phosphorylation (e.g., ATP5F1B), together with activation of calcium signaling (e.g., SLC8A1, ADCY9) and reinforcement of antioxidant/one-carbon and glucose-branch pathways (e.g., SHMT2, PGAM2). These coordinated transcript-protein changes indicate a shift from rapid cytosolic ATP supply to mitochondrial ATP production while buffering Ca[2+] overload and reactive oxygen species. Collectively, our results delineate the physiological and molecular adjustments that enable E. carinicauda to cope with sulfate conditions and provide mechanistic targets for selective breeding and water-quality management in saline-alkaline aquaculture.

A Selective RAG-Enhanced Hybrid ML-LLM Framework for Efficient and Explainable Fatigue Prediction Using Wearable Sensor Data.
Bioengineering (Basel, Switzerland), 13(1):.
Fatigue is a multifactorial phenomenon affecting both physical and psychological performance, particularly in high-stress occupations. Although wearable sensors enable continuous monitoring, conventional machine-learning (ML) models can produce unstable, weakly calibrated, and opaque predictions in real-world settings. To improve reliability and interpretability, we developed a selective Retrieval-Augmented Generation (RAG)-enhanced hybrid ML-LLM framework that integrates the efficiency of ML with the reasoning capability of large language models (LLMs). Using wearable and ecological momentary assessment data from 297 emergency responders (9543 seven-day windows), logistic regression, XGBoost, and LSTM models were trained to classify fatigue levels dichotomized by the median of daily tiredness scores. The LLM was selectively activated only for borderline ML outputs (0.45 ≤ p ≤ 0.55), using symbolic rules and retrieved analog examples. In the uncertainty region, performance improved from 0.556/0.684/0.635/0.659 to 0.617/0.703/0.748/0.725 (accuracy/precision/recall/F1). On the full test set, performance similarly improved from 0.707/0.739/0.918/0.819 to 0.718/0.741/0.937/0.827, with gains confirmed by McNemar's paired comparison test (p < 0.05). SHAP-based ML interpretation and LLM reasoning analyses independently identified short-term sleep duration and heart-rate variability as dominant predictors, providing transparent explanations for model behavior. This framework enhances classification robustness, interpretability, and efficiency, offering a scalable solution for real-world fatigue monitoring.

A Prevention-Focused Geospatial Epidemiology Framework for Identifying Multilevel Vulnerability Across Diverse Settings.
Healthcare (Basel, Switzerland), 14(2):.
Background/Objectives: Geographic Information Systems (GIS) offer essential capabilities for identifying spatial concentrations of vulnerability and strengthening context-aware prevention strategies. This manuscript describes a geospatial architecture designed to generate anticipatory, place-based risk identification applicable across diverse community and institutional environments. Interpersonal Violence (IPV), one of several preventable harms that benefit from this spatially informed analysis, remains a critical public health challenge shaped by structural, ecological, and situational factors. Methods: The conceptual framework presented integrates de-identified surveillance data, ecological indicators, environmental and temporal dynamics into a unified spatial epidemiological model. Multilevel data layers are geocoded, spatially matched, and analyzed using clustering (e.g., Getis-Ord Gi*), spatial dependence metrics (e.g., Moran's I), and contextual modeling to support anticipatory identification of elevated vulnerability. Framework Outputs: The model is designed to identify spatial clustering, mobility-linked risk patterns, and emerging escalation zones using neighborhood disadvantage, built-environment factors, and situational markers. Outputs are intended to support both clinical decision-making (e.g., geocoded trauma screening, and context-aware discharge planning), and community-level prevention (e.g., targeted environmental interventions and cross-sector resource coordination). Conclusions: This framework synthesizes behavioral theory, spatial epidemiology, and prevention science into an integrative architecture for coordinated public health response. As a conceptual foundation for future empirical research, it advances the development of more dynamic, spatially informed, and equity-focused prevention systems.

ESP Quick Facts
ESP Origins
In the early 1990's, Robert Robbins was a faculty member at Johns Hopkins, where he directed the informatics core of GDB — the human gene-mapping database of the international human genome project. To share papers with colleagues around the world, he set up a small paper-sharing section on his personal web page. This small project evolved into The Electronic Scholarly Publishing Project.
ESP Support
In 1995, Robbins became the VP/IT of the Fred Hutchinson Cancer Research Center in Seattle, WA. Soon after arriving in Seattle, Robbins secured funding, through the ELSI component of the US Human Genome Project, to create the original ESP.ORG web site, with the formal goal of providing free, world-wide access to the literature of classical genetics.
ESP Rationale
Although the methods of molecular biology can seem almost magical to the uninitiated, the original techniques of classical genetics are readily appreciated by one and all: cross individuals that differ in some inherited trait, collect all of the progeny, score their attributes, and propose mechanisms to explain the patterns of inheritance observed.
ESP Goal
In reading the early works of classical genetics, one is drawn, almost inexorably, into ever more complex models, until molecular explanations begin to seem both necessary and natural. At that point, the tools for understanding genome research are at hand. Assisting readers reach this point was the original goal of The Electronic Scholarly Publishing Project.
ESP Usage
Usage of the site grew rapidly and has remained high. Faculty began to use the site for their assigned readings. Other on-line publishers, ranging from The New York Times to Nature referenced ESP materials in their own publications. Nobel laureates (e.g., Joshua Lederberg) regularly used the site and even wrote to suggest changes and improvements.
ESP Content
When the site began, no journals were making their early content available in digital format. As a result, ESP was obliged to digitize classic literature before it could be made available. For many important papers — such as Mendel's original paper or the first genetic map — ESP had to produce entirely new typeset versions of the works, if they were to be available in a high-quality format.
ESP Help
Early support from the DOE component of the Human Genome Project was critically important for getting the ESP project on a firm foundation. Since that funding ended (nearly 20 years ago), the project has been operated as a purely volunteer effort. Anyone wishing to assist in these efforts should send an email to Robbins.
ESP Plans
With the development of methods for adding typeset side notes to PDF files, the ESP project now plans to add annotated versions of some classical papers to its holdings. We also plan to add new reference and pedagogical material. We have already started providing regularly updated, comprehensive bibliographies to the ESP.ORG site.
