Harvard study links gut bacteria to lower anxiety levels

Researchers at Harvard University have identified specific gut microbiome compositions associated with reduced anxiety in humans. The two-year study, published today, strengthens evidence for the gut-brain connection. This discovery opens doors to microbiome-based mental health interventions.

Study reveals persistent THC use among fatal crash drivers

A new study presented at the American College of Surgeons Clinical Congress found that nearly 42% of drivers killed in crashes in Ohio had active THC in their blood, with levels far exceeding legal limits. The prevalence remained unchanged even after recreational cannabis legalization in 2023. Researchers urge stronger public messaging on the risks of driving after marijuana use.

Images show rifampicin's effects on E. coli bacteria

Scientists have captured the first detailed images revealing how the common antibiotic rifampicin disrupts E. coli bacteria at a molecular level. Using advanced cryo-electron tomography, researchers visualized the drug binding to bacterial machinery, halting growth. The findings, published in Nature, offer new insights into antibiotic mechanisms.

Study questions U-shaped pattern of happiness over lifespan

A new analysis of UK data challenges the long-held belief that happiness follows a U-shape through life, dipping in midlife before rising again. Researchers found that well-being remains stable or slightly increases with age. This finding, published in Psychological Science, suggests the curve may not be universal.
