By tacking drugs onto molecules targeting rogue brain cells, medical researchers have alleviated symptoms in newborn rabbits that are similar to those of cerebral palsy in children.

Activity cuts the risk of Alzheimer's disease and slows cognitive decline, even in the very old, according to a new study. The study is one of the first to show that activity of all sorts benefits people over age 80, even if they're not "exercising."

A simple blood test can distinguish between people who are depressed and those who are not. The test examined a panel of 28 biological markers that circulate in the bloodstream and found that 11 of them could predict the presence of depression at accuracy levels that ranged from medium to large.
