Hackathon results suggest AI agents could make verifying research far more routine

A major study found that adults with depression show disrupted production of new neurons in the hippocampus, potentially weakening the brain’s ability to separate new experiences from painful memories. The researchers also identified broad molecular changes that could open the door to new treatments tailored to different biological forms of depression.

Gates Foundation pledges $540 million to a project often criticized for its opacity

People who reach 110 and beyond appear to have unusually large numbers of rare immune cells capable of killing abnormal cells. These CD4 cytotoxic T cells became more common with age and often expanded into large groups of nearly identical cells, suggesting the immune system was repeatedly responding to persistent threats.

Researchers re-create the chorus of noise produced by ancient insects

Common medications may reshape the gut microbiome long after the last dose is taken. In a study of more than 2,500 people, researchers found lasting microbial changes linked not only to antibiotics, but also to antidepressants, beta-blockers, acid-reducing drugs, and benzodiazepines. Some effects were still detectable years later, suggesting past medication use may strongly influence the gut bacteria people carry today.

Backyard bird feeders could become unexpected hotspots for H5N1 as Australia’s bird flu outbreak spreads, bringing species together in ways that rarely occur naturally. Experts say stopping feeding is safest, while smaller amounts of food, no hand-feeding, and careful cleaning can reduce the danger.
