Is a chatbot your doctor? Proceed with caution.
When researcher Nicholas Tiller began to feed health questions into chatbots as a test, he expected some imperfections — but not this level of failure. Five AIs, 250 questions, and a total score of just over 50% correct responses.

Surprising links between autism, Alzheimer’s could change how we treat both

When early hints of a connection between autism and Alzheimer’s began to appear in the medical literature a few years ago, they struck him as implausible — one a condition of early brain development, the other drivingdecline in old age.

A digital detox may erase 10 years of social media brain damage, researchers say
Photo taken in Seoul, South Korea The young woman described to a jury what it was like to lose control of her life to social media. She began as a child, she said, and over time the habit expanded to fill nearly every available hour - late nights bleeding into early mornings, sleep gradually displaced.
