Worms survived Columbia disaster
Hundreds of worms that were part of an experiment aboard the doomed space shuttle Columbia have been found alive in debris recovered from the crash site, Nasa officials say.
The Caenorhabditis elegans worms, which are about the size of a pin head, were in a four kilogram (nine-pound) locker that was discovered in Texas several weeks ago.
However, the locker was not opened until this week, when experts were surprised to find that the worms, held in six canisters, each holding eight petri dishes, had survived.
