NASA - NASA-Funded Research Discovers Life Built With Toxic Chemical Discovered in the poisonous Mono Lake, California, this bacteria is made of arsenic, something that was thought to be completely impossible. While she and other scientists theorized that this could be possible, this is the first discovery.
