Hello, my lovely waivers. It is me, your fearless co-host, Emily Kwong, here with a quick,

free ask. Right now, on the app or platform where you're listening, can you leave us a rating or review?

Like this one from Tristan, who says, howdy from Texas. I love y'all's show. It is always a way for me to

learn more about the world, especially as a student. I learn more than I would

at school, listening to y'all, but also listen to your teacher. Tristan says, thanks y'all so

much for being an excellent source of knowledge. Oh, listeners like Tristan, we appreciate you

so much. You help people find our show. So keep it coming. Write a few bars, drop it into the review section,

give us some stars, and spread the shortwave word. All right, onto the news roundup.

You're listening to Shortwave from NPR.

Hey, short waver is Regina Barber here.

And Emily Kwong with our biweekly Science News Roundup featuring the host of All Things Considered. And today we have one of our favorites, the amazing space nerd, Scott Detrow. I'm back. I'm here. I'm thrilled. I assume we're going to talk space. Otherwise, I'm leaving. But what other stories? First, we're going to talk about AI and the kind of the energy crisis there in, broken out by state.

Then... to talk space. Otherwise, I'm leaving, but what other stories? First, we're going to talk about AI and the kind of the energy crisis therein, broken out by state. Then we're going to talk about how scientists are learning more about an ocean moon of Saturn. And finally, after going to space, we're going to come back to Earth to talk about chameleons and what makes them so weird and cool. Okay. These are two joyous, interesting things and one, existential downery thing.

So I can, I'll take that ratio.

Sounds about right.

Excellent.

You're listening to get to space.

But before that one, where do you want to start?

Let's, since it seems the least joyous, let's start with AI computing.

We talk a lot about AI these days, and there's a lot of concern about the power it's sucking up. Yeah, it truly. A lot of AI computing relies on data centers. Data centers are

these big buildings which gobble up gigawatts of energy, sometimes millions of gallons of water

for cooling. And as tech companies try to make good on AI's potential, there is an energy

crisis in the making.
