A Simpler Way to Define What Makes a Planet

A new approach classifies 99 percent of all known exoplanets, requiring only estimates of the star’s mass and the planet’s mass and orbital period to classify them. Since the late 1980s, scientists have discovered nearly 5,000 planetary bodies orbiting stars other than the sun. But astronomers are still working on what exactly we should call […]

New Discovery Could Lead to Better Recovery After Stroke

Scientists from UCLA have identified a molecule (GDF10) that signals brain tissue to form new connections after a stroke. The finding could eventually lead to a new treatment to promote brain repair and functional recovery in people who have suffered a stroke, which is the leading cause of serious long-term disability in adults. The five-year […]
