Researchers say AI chatbots may blur the line between reality and delusion
A new study suggests AI chatbots may do more than spread misinformation — they can actively strengthen a user’s false beliefs. Because conversational AI often validates and builds on what users say, it can make distorted memories, conspiracy theories, or delusions feel more believable and emotionally real. Researchers

Brain scans reveal a shocking difference between psychopaths and other people
Scientists have uncovered a striking brain difference linked to psychopathy: people with psychopathic traits were found to have a striatum — a brain region tied to reward, motivation, and decision-making — that was about 10% larger on average than those without such traits. Using MRI scans and psychological assessments

MIT scientists discover millions of “silent synapses” in the adult brain
MIT neuroscientists have uncovered a surprising secret hidden in the adult brain: millions of “silent synapses,” dormant connections that lie in wait until new learning calls them into action. Once thought to exist only in early development, these inactive links make up about 30% of synapses in the adult cortex and can
