Bending spy planes

Fri, 2010-03-26 08:30 -- John Hawks

An unexpected source of decompression sickness: the U-2 spy plane.

As the number of flights increases, some of the plane’s 60 pilots have suffered from the same disorienting illness, known as the bends, that afflicts deep-sea divers who ascend too quickly.

Relaxing recently in their clubhouse at Beale Air Force Base near Sacramento, Calif., the U-2’s home base, several pilots said the most common problems are sharp joint pain or a temporary fogginess.

I lecture every year about high-altitude adaptation in humans, but this is a nice example of the opposite!

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
