Scientists have long suspected that the sex chromosome that only males carry is deteriorating and could disappear entirely within a few million years, but until now, no one has understood the evolutionary processes that control this chromosome's demise.
It's a terrible sight: hundreds of dead seabirds washed up on the seashore. These catastrophic events occur in the winter and are known as winter wrecks. No one knows why the birds perish, and it is almost impossible to study the animals out in stormy winter seas to find out how they meet their fate.
The shuttle Endeavour was to perform a backflip Friday so astronauts on the International Space Station can inspect it for damage before docking, NASA said. Station astronauts were to photograph the shuttle's underside for any damage suffered Wednesday during launch when pieces of thermal foam peeled off the external fuel tank, The New York Times reported Friday. A preliminary review Friday from a camera mounted on the shuttle's robotic arm showed minor dings in some thermal protection tiles, NASA said. We don't expect any issues.

The United States and China are racing to see who can make dirty coal cleaner by trapping emissions and pumping them deep underground, sources said. The technology, called carbon capture storage, got a boost last month when President Barack Obama announced a $1 billion revamp of a near-zero-emissions coal-fired power plant in Illinois called FutureGen.
