Neuroscience Autistic brains react less to being told "you're wrong," new study finds. People with autism showed weaker brain responses to negative feedback, and unlike others, their reactions didn't change with task difficulty, which may help explain why adapting to change feels harder.

Neuroscience When the UK made teens stay in school one extra year (until age 16) in 1972, people who got that extra year had fewer dementia diagnoses nearly 50 years later. The benefit even held for people with high genetic risk, suggesting schooling itself protects the brain and your genes aren't your destiny.

Neuroscience Scientists made a 'low-oxygen hypoxia pill': two drugs that make blood release less oxygen into tissues. Given daily to mice that already had Parkinson's-like movement problems, it improved their movement within 1-2 weeks. It also more than doubled lifespan in mice with a rare energy disorder.

Neuroscience Magic mushroom compound psilocybin grows new brain connections within 24 hours and repairs circuits damaged by chronic stress in mice. Scientists found the brain rewiring runs on a different pathway than the trip itself, opening the door to fast-acting depression drugs without the hallucinations.

These extinct big cats were closely related to pumas, and ate a diet high in nitrogen, suggesting their main prey was fish, probably salmon.
