Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.

Time flies when you learn in super cool stuff.

I'm Nate.

And I'm Callie. If you're dropping in for the first time, welcome to Curiosity,

where we aim to blow your mind by helping you to grow your mind.

If you're a loyal listener, welcome back.

Today you'll learn about a potential obstacle to human flight to Mars, a discovery in a

Leocean cave that is sending archaeologists back to the drawing board, and how new technology could

keep us cool in a warming world without adding to the problem of climate change.

Without further ado, let's satisfy some curiosity.

Have you ever got Space Brain?

Uh, no, I've heard it exists, but I'm I'm perfect my brain is a perfect. What's that word?

Specimen. Oh, yeah, okay, so all right. It's possible I space out from time to time. Who doesn't?

It's fine. Well, a new study has found that astronauts who spend months in space can get a literal form of space

brain that can take years to resolve.

Ooh boy we could file this story under more reasons it's going to be really hard to go to

Mars, huh? It is a whole genre of curiosity daily stories isn't it? Well it might not be the biggest problem, but it definitely needs some focus.

This study found that the fluid filled chambers in the brain of astronauts tend to expand in microgravity, and it turns out it can take three years

for these structures to shrink back to normal.

Mm, okay I know you said it might not be the biggest problem but that doesn't sound great

if we're being honest.

Fluid-filled brains.
