Hey, it's Manus here. Just a quick note to say that every year NPR does a survey to help us better

understand how our listeners spend time with podcasts. So if you have a moment, please help us out by

completing our short anonymous survey at npr.org slash podcast survey, all one word. Your feedback is so important to us, and we really want to hear what you like and what you don't like so that we can keep making our podcasts even better. So please go to npr.org slash podcast survey, all one word, to complete this brief survey and thank you.

Okay, so now on with the show.

We're working hard on new episodes.

So for this week, we surveyed the team and picked one of our favorites from the archive to share with you.

It's an episode that aired back in May 2020 called

Biology of Sex. And it explains how much we are still learning about the science that

determines our biological sex. It's particularly fascinating and important as we begin to live

in a society with laws and attitudes that are more

accepting of the different ways people express their gender. So enjoy it again or for the first time.

I'll be back next week with a brand new show. See you then. This is the TED Radio Hour.

Each week, groundbreaking TED Talks.

Our job now is to dream big.

Delivered at TED conferences.

To bring about the future we want to see.

Around the world.

To understand who we are.

From those talks, we bring you speakers and ideas that will surprise you.

You just don't know what you're going to find.

Challenge you.

We truly have to ask ourselves, like, why is it noteworthy?
