Hey, it's Matt. Today's episode is going to be a bit different. Instead of the weeds, you're

going to hear an episode of a new podcast from my friends at Vox. It is called Unexplainable.

Unexplainable is all about the most fascinating mysteries in science. Each week, the team will

dive into one scientific question that remains unanswered. Talk to scientists and experts about

how they try to find answers to these questions. The show is hosted by Noam Hasadfeld.

It's going to feature reporting from producer Bert Pinkerton, Vox Science reporter Brad Resnick.

It's a great team, and this episode is all about the nose. We know the basic mechanics of how

smell works, but we ultimately don't know why one substance smells one way, while another smells

different. Noam speaks to one researcher who is built a robot nose that can smell even more

accurately than a dog to see if he's gotten any closer to answering this question.

Other upcoming episodes dig into everything from what really lies at the center of the earth

to why mysterious balls of lightning have been recorded throughout history.

Talk about what we don't know can be uncomfortable, but right now it's more important than ever before.

So if you enjoy your weekly deep dives into the weeds on policy, I think you will like this show.

You can follow unexplainable in your favorite podcast app to get new episodes every Wednesday morning.

This is unexplainable. I'm Noam Hasadfeld. I'm hanging out here with our senior science reporter,

Brian Resnick. Hey, so this is a show about unanswered scientific questions. And Brian,

I wanted to talk to you because when we were initially talking about topics we might want to cover

on the show, you told me there was this mystery you wanted me to look into about the nose.

Yeah, I haven't done any research on this myself, but I do remember seeing a YouTube video that

it was going on about like how smell is just still a mystery.

Yeah, we still don't know everything about how smell works. And it's kind of shocking because
