It's tough to dream up a use for arsenic soup, but one research team finally has: They're making bricks out of it. » 3/31/14 5:32pm 3/31/14 5:32pm

NASA's arsenic-life findings debunked in two just-published studies

In 2010, NASA called a press conference to make one of the biggest announcements in scientific history: researchers had discovered an unusually hardy bacterium that could not only tolerate exposure to arsenic, but actually incorporate the poisonous element into its DNA. The team's findings, if correct, would have gone… » 7/09/12 7:15am 7/09/12 7:15am
