DNA Sequencing in Space Could Protect Astronaut Health

NASA astronauts are opening new doors in the worlds of science and medicine by sequencing DNA in all sorts of extreme environments, including, for the first time, the microgravity of the International Space Station. NASA astronaut and biologist Kate Rubins has sequenced DNA in space, marking the first time this has been done. "Welcome to systems biology in space," Rubins said in a statement after the first few DNA molecules had been sequenced successfully.
