It’s now or never: mating is highly synchronised in a monestrous ungulate

By utilizing activity sensor data to track oestrus in wild European roe deer, this study reveals that mating is highly synchronized and largely independent of individual traits, suggesting that reproductive phenology is primarily driven by the timing of delayed implantation rather than conception dates.

Ulcerative Colitis Is Associated with Distinct Colonic Mucosa-Associated Microbial Profiles in a North Indian Cohort

This study characterizes the distinct mucosa-associated microbial profiles of North Indian patients with ulcerative colitis, revealing a unique dysbiosis marked by an elevated Firmicutes-to-Bacteroidota ratio, specific taxonomic shifts, and altered microbial interaction networks compared to healthy controls.

Restoring erythromycin efficacy by the repurposed drugs desloratadine and zinc gluconate as adjuvants via bacterial efflux pump inhibition

This study demonstrates that the repurposed drugs desloratadine and zinc gluconate act as effective efflux pump inhibitors that synergize with erythromycin to restore its efficacy against multidrug-resistant bacteria both in vitro and in a mouse model, a mechanism further validated by molecular docking and simulation studies targeting the AbeJ protein.

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.
