Chemists routinely optimize reactions to maximize the yield of their desired products, but understanding why those reactions work can require laborious experiments that track reactions over time. Researchers at the University of Tokyo have developed a method to extract hidden information about reaction speeds from yield data obtained during reaction optimization, using machine learning and rate equations developed by chemists.

Why rheumatoid arthritis pain may persist even when inflammation is under control
Pain and fatigue in rheumatoid arthritis can persist even after inflammation improves, with depression, poor sleep, obesity, smoking, and chronic pain potentially helping sustain symptoms. Researchers say identifying these hidden drivers could prevent unnecessary medication chang

This “rare” autism-linked genetic disorder may be far more common than scientists thought
A major analysis suggests Phelan-McDermid syndrome, a genetic disorder closely linked to autism, may affect about 1 in 7,300 people and more than 45,000 Americans. Researchers warn that thousands of cases may remain hidden because genetic testing is often not performed, even as t
