Understanding the mind of a cocaine addict

A protein known for its role in Rett syndrome — a rare genetic brain disorder — also works to regulate cocaine addiction, new research shows.

Cheap drugs are just as effective at preventing heart disease, long-term study shows

Pricey drugs to reduce blood pressure appear no better at preventing heart disease than cheap, generic diuretics, which have been around for decades. This is the result of a 13-year study of roughly 33,000 Americans who use anti-hypertensive drugs.
