Apparently spending time in outer space can actually lead to long-term changes in your DNA. A fascinating recent study on the world’s only identical twin astronauts, Scott and Mark Kelly, showed that spending nearly a year on the International Space Station (ISS) changes how your genes are expressed.

Scott went to the ISS for 340 days while his retired, identical twin brother, Mark, stayed here on earth. When Scott returned, researchers compared his DNA to his brother’s. Identical twins have virtually identical DNA (though mutations that accumulate during your lifetime mean their DNA isn’t 100% identical), so this was an …read more
