 Inspired by the stillsuits that recycle water in Frank Herbert's Dune series, researchers have designed a system that turns astronauts' pee into nice, clean drinking water while they're suited up. The researchers reported on their prototype in the journal Frontiers in Space Technology. Joining me today is Sophia Etlin, a researcher at Weill Cornell Medicine in New York. Sophia, welcome to Science Friday. Hi, Rachel. Thank you.
