I don't know why an excellent science site is running the story this week. There's no news peg I can see, and the space launch doesn't happen until next spring.
But it is still interesting that identical astronautical twin brothers are teaming up to let scientists compare human bodies in space to those on the ground.
Scott Kelly will fly to the ISS for a year. Brother Mark will stay down here with Gabby. Each will be poked and prodded and tapped to observe and compare physiological changes.
It sounds like a reasonable experiment to me, but I note a flaw. Let's reverse the roles and send Mark up there, sparing Earthlings a full year of his pestering us about new gun laws.
