Earthworms sent into space may be able to live longer. The common worms, of species C. elegans, were sent to the International Space Station (ISS) onboard the Dutch DELTA mission. Scientists found the worms adapted to the change by suppressing a protein that normally accumulates within aging muscle. They also found a group of genes in the worms were expressed at lower levels. Recreating the same situation on Earth, the scientists found worms who suppressed these two functions tended to live longer.
