Science writer Carl Zimmer talks to Geneticist Christopher Mason at Weill Cornell Medicine in NYC about his mission to study the DNA of astronauts. He’s part of a team of scientists who are examining blood and other samples from astronaut Scott Kelly, who recently spent 340 days aboard the International Space Station. They’re looking at how life in space alters astronauts at a molecular level. They hope their discoveries can help protect astronauts on long-distance trips, such as the proposed mission to Mars.
Importantly, they will also be looking at epigenetic differences (relevant, since epigenetics have been a popular topic lately).
