Turns out you don't need a dose of Gamma Rays, or a Spider bite to change your DNA. Just need to live in space.

A day after our President announced a possible "Space Force", a story comes out stating that living in space changes your DNA.

KSAT12 is reporting a CNN story that says Astronaut Scott Kelly's DNA no longer matches his twin brother.

Kelly spent a year in space and is now 7% different from his twin. NASA did a study to see if anything changed and preliminary results say "yes".

I can only imagine that this will make everyone avoid the Space Force recruiter. Go Army!
