0:00.0	Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.
0:09.0	Time flies when you're learning super cool stuff.
0:11.0	I'm Nate.
0:12.0	And I'm Callie. If you're dropping in for the first time welcome to curiosity
0:15.2	where we aim to blow your mind by helping you to grow your mind. If you're a loyal
0:18.9	listener welcome back. Today you'll learn about how astronaut blood is mutating, how our screens are aging us, and the potential extinction event of the snow crab.
0:30.0	Without further ado, let's satisfy some curiosity.
0:32.8	Cal, astronauts are some of the healthiest people on and off of the planet,
0:37.9	but going to space might be messing with their blood.
0:41.0	Well, what do you mean?
0:42.2	Well, there are some concerns about the future of deep space travel and exploration, like the potential Artemis mission to Mars.
0:48.0	According to new research, astronauts have genetic mutations in their blood from being in space, even those who went on short missions.
0:56.0	It changed their blood and their genetics? I mean, I've always wanted to go to space, but that's pretty concerning.
1:02.0	It does make me think twice about doing one of those
1:04.2	commercial space flights the billionaires are promoting. That's actually part of the

1:12.4	so along with the Mars missions are seeming a lot more possible.
1:12.6	So along with the Mars missions, it means a lot more people are going to be spending a lot more time in space.
1:18.1	We should definitely know what that does to the human body.
1:21.4	All right, so how did they pull off this study?
1:23.4	Were astronauts mailing in their blood
1:25.2	from the International Space Station?
