I'm Philipp Strasberg, a theoretical physicist at the Cantabrian Institute of Physics and author of the recent Scientific American feature, Why We Probably Live in a Multiverse, where I explore the Many Worlds interpretation of quantum mechanics and how recent experimental advances have renewed interest in this once-fringe theory.

On October 27 at 10 a.m. EDT, I’ll be answering your questions about quantum mechanics and the possibility of a multiverse in an AMA hosted by Scientific American.

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.

Psychology A study using genetic, health and Fitbit data found that higher physical activity was associated with weaker links between genetic risk for depression and symptom severity. Both daily steps and moderate-to-vigorous exercise showed this pattern, suggesting activity may help buffer inherited risk.

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