A study finds that over 20% of young adults use cannabis or alcohol to fall asleep, with cannabis most common. Researchers warn this habit can disrupt sleep, increase tolerance, and raise the risk of long-term sleep and substance-use problems.

Scientists have identified a tiny helper protein that supports appetite control. When it fails, hunger signals weaken, increasing obesity risk. This offers new insight into genetic appetite regulation and potential future weight loss treatments.

AI systems used to detect cancer can also infer patient demographics from tissue slides, causing hidden bias. A new Harvard study explains why this happens and shows how smarter training can sharply reduce disparities in AI driven cancer diagnosis.
