Spotted: Location-informed Reidentification of Hyenas and Leopards in Camera Trap Surveys

The paper introduces "Spotted," a human-in-the-loop framework that enhances animal re-identification in camera trap surveys by integrating visual similarity with spatio-temporal feasibility priors, significantly improving accuracy for hyenas and leopards while reducing the expert review burden.

Personality Traits Moderate the Associations Between Autonomic Regulation and Psychological Stress During VR-Mediated Communication

This study demonstrates that personality traits significantly moderate the relationship between autonomic regulation (specifically heart rate variability) and psychological stress during virtual reality-mediated communication, suggesting that future digital mental health interventions should be tailored to individual personality profiles.

Visual predatory stimulus causes changes in swimming performance irrespective of acoustic conditions in the Trinidadian guppy (Poecilia reticulata)

This study demonstrates that while anthropogenic noise increases swimming speed in Trinidadian guppies, it does not significantly alter their visual antipredator responses, suggesting that visual predatory stimuli drive behavioral changes irrespective of acoustic conditions.

Modeling Psychosocial Stress-Cortisol Interactions in Menstrual Cycle Dynamics through Machine Learning: A Systems Engineering Approach

This study employs a systems engineering approach combining classical statistics and machine learning to demonstrate that serum cortisol and temperament (Mizaj) are critical predictors of menstrual cycle dynamics, revealing that Safrawi and Balghami temperaments significantly influence cycle regularity and flow while cortisol and BMI effectively predict pain and regularity.

Comprehensive transcriptomic analysis of BjGL1-knockout Brassica juncea: novel insights into leaf trichome formation and defense-associated biological processes

This study utilizes RNA sequencing to characterize the transcriptomic profiles of *BjGL1*-knockout *Brassica juncea*, revealing that the loss of trichomes leads to significant downregulation of genes involved in secondary metabolite biosynthesis, transport, and defense pathways, thereby elucidating the molecular mechanisms linking trichome formation to plant resistance.

SERPINE1 as a critical CAF-associated gene promotes myCAF phenotype activation and exosome-mediated gastric cancer progression

This study identifies SERPINE1 as a critical CAF-associated gene in gastric cancer that drives myCAF phenotype activation via the PI3K-Akt pathway and promotes tumor progression and MDSC infiltration through exosome-mediated mechanisms, highlighting its potential as a therapeutic target.

A genus betrayed by its chloroplast: comparative plastomics of 54 Corymbia species exposes plastid paraphyly and microevolutionary signatures

This study analyzes the plastomes of 54 *Corymbia* species to reveal structurally conserved yet microevolutionarily dynamic genomes, identifying hypervariable regions and confirming the genus's plastid paraphyly through the inclusion of *Angophora costata* within its clades.
