Could one amino acid help explain why men tend to live shorter lives?

A UK Biobank cohort and Mendelian randomization study involving 272,475 participants linked higher circulating tyrosine with greater all-cause mortality and genetically predicted higher tyrosine with shorter lifespan. After accounting for phenylalanine, the relationship with shorter lifespan was clearest in men, while findings in women were less consistent, suggesting a potential sex-specific role for tyrosine in longevity.

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.

Laughter therapy eases breathlessness in people with COPD

A clinical trial for patients with chronic obstructive pulmonary disease (COPD) shows that laughter therapy can reduce breathing difficulties and is as effective as more traditional breathing exercises. The research is presented at the European Respiratory Society (ERS) Congress in Barcelona, Spain.

What four pregnancy eating patterns revealed about mothers and newborns

Researchers analyzing 1,404 pregnant women in Germany identified four distinct dietary patterns that differed substantially in maternal BMI, socioeconomic status, age, and gestational weight gain. A vegetable-rich pattern was also associated with selected neonatal measures, including greater birth length, but most newborn associations were modest or nonsignificant, and the observational study cannot establish causality.

Bird feeding offers emotional and meaningful well-being benefits

More than 56 million U.S. adults feed wild birds. For many, filling a feeder is a routine way to connect with birds and other wildlife. But researchers know less about what that interaction may mean for the people doing it.

Tumor environments sculpt diverse natural killer cells for cancer therapies

For decades, natural killer (NK) cells have been classified into two main groups based on surface markers: one specialized for cytokine production and the other for direct killing.

What your gut microbes may have to do with how your brain ages

This review examines how diet-driven changes in the gut microbiota and microbial metabolites may influence cognitive aging through immune, metabolic, neural, endocrine, and barrier-related pathways. It highlights SCFAs, tryptophan-derived metabolites, and bile acids as key signaling mediators while emphasizing that much of the mechanistic evidence remains preclinical and human evidence is largely associative.
