This May 2021 episode of the Unexplainable podcast explores our sense of smell, its inner workings, and our surprising lack of knowledge surrounding it.

Humans have five basic senses: sound, sight, touch, taste, and smell. But smell seems to be the most mystifying.

Although it's one of our basic senses, smell is the one we seem to understand the least.

But the fact that it's an enduring mystery has only encouraged some scientists, who refuse to be defeated.

No-One Nose is an episode of Vox's Unexplainable podcast series.

Unexplainable is a show about everything we don't know, zooming in on some of the most fascinating unanswered questions in science.

Hosted by reporter, producer, and composer Noam Hassenfeld, the episode uncovers the voices of experts and scientists as they dive into the unknown.

In this episode, Hassenfeld is joined by senior science reporter Brian Resnick as they explore the complex mechanisms hiding inside our nostrils.

Although we know very little about our nose and how we detect different scents, we're still making incredible progress.
