Living in space affects cells at the genetic level, according to a study of roundworms.

Analysis of nematode worm species, known as Caenorhabditis elegans, which were sent to the International Space Station has revealed “subtle changes” in close to 1,000 genes, with stronger effects seen among cells in the nervous system.
