MAD SCIENCE: Minute pinworms survive Columbia space shuttle crash

According to a recent BBC science story, hundreds of worms that were part of an experiment aboard 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 locker discovered in Texas several weeks ago.
The C elegans worms have a life cycle of seven to 10 days, so the ones found this week were likely to be four or five generations removed from the original space travel.
