Science Happens! With Carl Zimmer

The video explores the challenges of long-term space travel, focusing on a study involving astronaut Scott Kelly, who spent a year in space, and his twin brother Mark, who remained on Earth. The study aims to understand genetic and epigenetic changes due to space travel. It highlights the technical challenges of collecting and analyzing biological samples in space, the role of epigenetics in aging, and the potential risks for astronauts. The research is part of ongoing efforts to ensure astronaut safety on future missions to Mars.

What is the significance of studying epigenetics in the context of long-duration space missions?

In what ways might space travel affect the aging process of astronauts?
