After returning from space, astronaut has no lingering, major epigenetic differences from earthbound twin brother
In a landmark study, a group of U.S. scientists from Johns Hopkins, Stanford University and other institutions has found no long-lasting, major differences between the epigenomes of astronaut Scott Kelly, who spent a year in space aboard the International Space Station, and his twin brother, Mark, who remained on Earth.
