    Ant brains reveal how evolution turned hunger into parenting

    Researchers discovered that two chemical signals in clonal raider ants influence their behavior between caring for larvae and foraging, suggesting that ant parenting evolved from brain systems originally controlling hunger. Similar signals in mammals indicate a shared evolutionary mechanism across species.

    For the first time, scientists pinpoint the brain cells behind depression

    Scientists identified two specific brain cell types—neurons linked to mood and stress, and immune-related microglia cells—that behave differently in people with depression. Using advanced genetic tools on donated brain tissue, the study reveals biological disruptions in key brain systems, reinforcing that depression has a biological basis.
