"I grew up wanting to fly," says Graham Bowen-Davies. "I guess I just settled for being an engineer."
He's standing on an indoor track in southern Maryland, watching a giant helicopter take flight. At the end of each of its four spindly arms — arms he helped design and build — a giant rotor churns the air. In the cockpit sits the engine: a 0.7-horsepower, 135-pound graduate student named Kyle Gluesenkamp.
Gluesenkamp is pedaling like crazy to keep the rotors spinning and the craft aloft.
For nearly a decade, scientists and Northwest tribes in Washington state fought bitterly over whether to bury or study the 9,500-year-old bones known as Kennewick Man. Scientists won the battle, and now, after years of careful examination, they're releasing some of their findings.
For starters, Kennewick Man was buff. I mean, really beefcake. So says Doug Owsley, head of physical anthropology at the Smithsonian's National Museum of Natural History, and the man who led the study of the ancient remains.
