Spending a year in space not only changes your outlook, it transforms your genes.

Preliminary results from NASA’s Twins Study reveal that 7% of astronaut Scott Kelly’s genes did not return to normal after his return to Earth two years ago.

The study looks at what happened to Kelly before, during and after he spent one year aboard the International Space Station through an extensive comparison with his identical twin, Mark, who remained on Earth.

But we know better, don’t we? It was not Scott Kelly’s DNA that changed but his Evil Twin Brother’s for hanging around Gabby Gifford.

Gun Control will not only kill you but you end up like Jeff Goldblum in The Fly.
