Regional Differentiation of Ground–Active Beetle Assemblages Across Contrasting Dryland Alfalfa Agroecosystems

Perennial crops can provide a shared habitat template for arthropods, but whether regional differentiation persists among fields of the same crop in drylands remains unclear. From 2020 to 2022, we surveyed ground–active beetles at 55 perennial alfalfa sites across mountainous, oa...

Beyond Single‐Cause Explanations: An Integrated Framework for Crisis Learning in Public Organisations: A Survey Experiment in China

ABSTRACT Drawing on performance feedback, attribution, and accountability theory, this study investigates how the frequency of crises, the type of causal attribution, and the geographic location of an event jointly influence crisis learning among Chinese public sector actors. The...

Effects and social design features of physical activity interventions on loneliness and subjective well-being in older adults: a systematic review

Physical activity is promoted in later life, yet its capacity to reduce loneliness or improve subjective well-being remains uncertain when social contact is incidental rather than intentionally designed. This review synthesised controlled intervention evidence and examined how so...

Shiitake mushroom cap-stem adaptive matching and harvesting point localization for edge devices

Robotic shiitake harvesting requires reliable target perception, individual-level structural association, physical measurement, and actionable picking-point localization under edge-computing constraints. To address these requirements, this study developed a color-and-depth edge p...

Multi-omics analyses identify PGAM2-associated energy-metabolism signatures linked to bull testis size divergence and spermatogenic potential

Testicular development and spermatogenic capacity are important determinants of male reproductive potential and breeding value in livestock. However, the molecular features associated with natural variation in testicular size remain incompletely understood. In this study, large-t...

Proximal socioecological profiles and their association with psychosexual health among adolescent students: a cross-sectional study

To identify the proximal socioecological profiles of adolescents and explore their associations with psychosexual health. A questionnaire survey was administered to 3,419 students aged 14–19 from three high schools in Shandong Province. Based on the socialecological theory, ten p...

An atlas of colonization factors in the mouse gut microbiome reveals phylogenetically structured repertoires and infection-stage-associated variation during Toxoplasma gondii infection in mice

ABSTRACT Colonization factors (CFs) comprise CF-associated gene families related to microbial establishment, persistence, host interaction, and gut ecological fitness, but their organization and variation in the mouse gut microbiome remain poorly defined. We integrated the Mouse...

White clover-tea intercropping modulates rhizosphere microbiome composition and structure

Leguminous plants are widely incorporated into intercropping systems because of their nitrogen-fixing capabilities. The effects of intercropping white clover on the composition and functional characteristics of rhizosphere soil microbiota in tea plantations were investigated. Met...

Windmill‐Type π ‐Extension Within Donor Moiety of Covalent Organic Framework Boosts Overall Photocatalytic Hydrogen Peroxide Production

ABSTRACT Covalent organic framework (COF)‐based catalysts are promising for overall photocatalytic hydrogen peroxide (H 2 O 2 ) production, yet the sluggish kinetics of water oxidation reaction (WOR) and inefficient charge carrier processes limit the catalytic performance. Herein...

Signaling resilience to tourists and investors through corporate philanthropic disaster giving

The tourism industry is highly susceptible to public crises. Drawing on signaling theory, this study proposes that corporate charitable disaster giving can function as a sustainability signal, aiding tourism firms in recovering from the negative impacts of such crises. Across eig...

Exogenous spermidine and the CaSPDS gene regulate salt tolerance by maintaining ROS homeostasis and photosynthetic function in pepper seedlings

Salt stress severely restricts pepper ( Capsicum annuum L.) growth and productivity by disrupting osmotic balance, damaging the photosynthetic system, and inducing excessive reactive oxygen species (ROS) accumulation. Spermidine (Spd), an important polyamine, plays critical roles...

The Timeless (Tim) Gene Participates in Circadian Rhythm Regulation of the Ridgetail White Prawn, Exopalaemon carinicauda

We previously found that period (per) may exert a positive regulatory effect on ovarian development under the modulation of circadian rhythms. This study further explores the function of the core clock gene timeless. Thus, we cloned the tim gene (Ec-tim) from the ridgetail white...

Genome-resolved analysis reveals disruption of gut microbial vitamin B and K 2 biosynthesis during Toxoplasma gondii infection in mice

ABSTRACT Toxoplasma gondii infection remodels the gut microbiome, yet its impact on microbial vitamin biosynthetic potential and host redox metabolism remains unclear. Here, we integrated mouse gut metagenomes with publicly available metagenome-assembled genomes (MAGs) to constru...

Endophyte-Mediated Aphid Resistance in Wheat via Chemical and Structural Defenses under Nonsterilized Soil Condition

Abstract Endophyte-based coatings enhance plant resistance and offer a sustainable alternative to chemical insecticides; however, their efficacy under nonsterilized soil conditions remains unclear. Here, we examined how nonsterilized soil conditions influence aphid resistance in...

Maternal microbiome promotes offspring ovarian reserve via bile acid metabolism

The maternal microbiome plays a crucial role in host ovarian function and fertility, yet its influence on in-utero ovarian development in offspring remains poorly understood. Here, we demonstrate that maternal antibiotic-induced microbiome disruption in mice leads to diminished o...

Design, Fabrication, and Performance Study of 3D‐Printed Multi‐Tooth Interlocking Discrete Functionally Gradient Stretchable Substrates

ABSTRACT Flexible hybrid electronics (FHE), which integrate the deformation capability of flexible substrates with the functional stability of rigid components, show broad application prospects in wearable devices and aerospace fields. Among these, functionally graded substrates...

RPS27L Maintains Nucleolar Homeostasis to Regulate Proliferation and Differentiation of Bovine Skeletal Muscle Satellite Cells

The in vitro expansion of bovine skeletal muscle satellite cells (SMSCs) is critical for cultured meat production. Here, we investigated the role of ribosomal protein S27-like (RPS27L) in regulating satellite cell proliferation and differentiation. RPS27L knockdown markedly inhib...

Poplar co-chaperone PdBAG12 negatively regulates wood formation by decreasing nuclear localization of PdC3H17

B-cell lymphoma 2 (Bcl−2)-associated athanogene (BAG) proteins, as the molecular chaperones, play prominent roles in regulating plant growth, development, and stress responses. Currently, it remains unclear the biological roles of BAG proteins in tree species. This study provided...

Evolution of mental health information-seeking behavior: a longitudinal text mining analysis from the pre-pandemic to the COVID-19 endemic era

Abstract This study investigates the longitudinal evolution of healthcare consumers’ information-seeking behavior regarding mental health issues, specifically depression, across the pre-pandemic (2018), peak-pandemic (2022), and post-pandemic endemic (2025) eras. Utilizing a larg...

Regulation of actin polarization by Edwardsiella piscicida during invasion of Sebastes schlegeli intestinal mucosa and cellular immune responses

Intestinal epithelial cells play a crucial role in teleost defence against complex aquatic environments. However, the study of intestinal mucosal immunity in teleosts has been hindered by the lack of reliable and specific marker genes to distinguish between different cell types....
