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

Time flies when you're learning 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 new high-tech mine in Minnesota, how scientists have created

a synthetic mouse embryo using stem cells and will explore a major breakthrough in the

cause of and treatment for Down Syndrome.

Without further ado, let's satisfy some curiosity.

All right, I know we're pretty excited about the shift from gas cars to electric cars,

but did you know one of the biggest challenges is getting the necessary materials to make the batteries?

I've heard some things about that. Isn't it stuff like a nickel and cobalt?

Exactly. We only have one active nickel mine in the US.

But recently, a mining company has proposed building a high-tech mine in rural Minnesota

to meet the growing need for the metal used in the US electric car batteries.

I didn't even realize we had nickel in Minnesota. I thought we

sourced it from the other side of the world. Right now we rely on Indonesia and the

Philippines for most of it, but Minnesota actually has a lot of

nickel, copper, and cobalt as a result of a 1.1 billion-year-old

volcanic eruption. The US does already have one nickel mined in Michigan, but experts say

its resources will be depleted by 2026. By having another domestic mine, the supply

chain will all be internal and make sure the materials aren't traveling all over the world

before being manufactured stateside. I'm still kind of stuck on the volcano in Minnesota. So what would this kind of
