In this Jan. 27, 2015 photo, Chilean biochemist Jenny Blamey looks at samples in her room aboard the Aquiles navy ship, near Antarctica's Almirantazgo Bay off Livingston Island, part of the South Shetland Island archipelago. "You don't have to be a rocket scientist to look around and see how extreme this environment is," said Blamey, the research director of the Biosciences Foundation in Chile who is studying the genetic material of microorganisms, essentially microbes that can't be seen.
