Brain Pathway Responsible For Obesity Found: Too Many Calories Send Brain Off Kilter
An overload of calories throws critical portions of the brain out of whack, reveals a new study. That response in the brain's hypothalamus -- the "headquarters" for maintaining energy balance...
Steve Fossett's Plane Found; Animals Likely Took Body
The U.S. adventurer's plane "disintegrated" when it hit a California mountain, experts said. The presence of bears and other scavengers likely explains why no body has been found.
