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 how feeling the

effects of racism might actually change the victim's brain chemistry,

how scientists have successfully completed the first embryo transfer in an endangered rhino,

and how handwriting increases brain connectivity.

Without further I do, let's satisfy some curiosity.

Black History Month is a time to celebrate the achievements and history of all black people in the U.S.

and give the black community the recognition it deserves after centuries of inequality and oppression.

And while it's important to reflect on the past and recognize the impact of black Americans on our society,

it's also absolutely necessary to be clear-eyed about the challenges that are

still present today. Oh absolutely and as far as we've come as a society there is

definitely work to be done. Absolutely and that's one reason a new research initiative from neuroscientists at Emory

University is so essential.

It looks at how racism affects the brain, and specifically how feeling the effects of racism against you can actually change your brain chemistry.

Okay, it's interesting that this hasn't been studied before.

So we've done stories on the effects of inherent bias in scientific studies, and they can have huge rippling effects.

Remember there's a story about how researchers have historically used male mice in their studies,

just for decades and decades which unwittingly caused gaps in effective treatments for some conditions for women?

That's right. Some drugs are built for men basically because of
