The vaginal microbiome may be an overlooked reservoir of antibiotic resistance
Researchers analyzed 1,957 vaginal metagenomic samples from 1,547 pregnant women and found that bacterial community structure was strongly associated with the diversity and distribution of clinically relevant antibiotic resistance genes. Lactobacillus crispatus-dominated communities carried comparatively few acquired resistance genes, while L. iners-dominated and anaerobe-rich communities showed greater resistance diversity, with PPROM associated with broader predicted resistance profiles among ARG-positive samples.

GLP-1 drugs looked promising for depression. The evidence tells a more complicated story
A systematic review of 43 studies found highly heterogeneous results for GLP-1 receptor agonists across animal models and human research assessing depression-, anxiety-, and stress-related outcomes. No study directly tested these drugs as a treatment for PTSD, and the available evidence does not currently support their use for depression or PTSD, although people with metabolic dysfunction may warrant further investigation.

Psilocybin microdosing sounds promising, but the strongest studies tell a different story
A systematic review of 11 studies involving 3,262 adults found that psilocybin mushroom and truffle microdosing was associated with reported improvements across areas including mental health, well-being, cognition, creativity, and social functioning. However, the evidence was methodologically weak and highly heterogeneous, the two placebo-controlled trials found no significant improvements, and inadequate adverse-event reporting means efficacy and safety remain uncertain.

What mothers eat in pregnancy may shape a child’s weight years later
A prospective study of 252 mother-child pairs found that higher combined maternal fruit and vegetable intake during pregnancy was associated with lower odds of overweight or obesity in children at age four. Total and natural fruit juice showed no association, whereas higher commercial fruit juice intake was associated with increased odds, though the authors emphasized that this finding was exploratory.

Deep sleep brain activity helps mice resist social stress
Most adult sleep is non-rapid eye movement (REM), which is restorative and promotes resilience to stressful conditions. However, the brain mechanisms for non-REM sleep's relationship to stress resilience remain unclear.
