Columbia researchers have found that adults who shortened their sleep by just 80 minutes a night for six weeks gained weight and were more sedentary.

A Dartmouth study finds that AI may cost doctors time when corresponding with patients by making them spend more time editing AI-drafted responses than it would take to write them. The researchers analyzed 146,000 conversations between patients and their primary care physicians from the online portal of a large healthcare system and found that automated responses frequently introduced errors and extraneous details. But the study provides a framework for generating "good" AI responses that align with how clinicians communicate and shows that adapting AI to individual physicians can reduce editing by 26%. The study was presented at the 64th Annual Meeting of the Association for Computational Linguistics.
