Running an entire marathon takes a lot of energy. Neuroscientist Carlos Matute knows this: he's run 18 of them. He wondered how runners' bodies get the energy they need to make it to the finish line. His new research in the journal Nature Metabolism may be the first step in answering the question – and suggests their brains might be (temporarily) depleting a fatty substance that coats nerve cells called myelin.

You're listening to Shortwave from NPR. Hey, Short Wavers, Regina Barber here. And Rachel Carlson. With our biweekly science news roundup featuring Juana Summers of All Things Considered.
Hey, Juana. Hi, excited to be here. I hear we're talking about one of my favorite things, running, and how running a marathon can change your brain.
Yep. Plus, we're talking about fermenting food in space and what it does to its taste.
And scientists have solved a longstanding mystery of how hordes of bats emerging from caves avoid bat-on-bat collisions.
I'm intrigued, y'all. All that on this episode of Shortwave, the science podcast from NPR.

All right. Just to start off, tell me about marathon running. I'm training for one myself, so I'm really interested in this story.
Yeah. Okay. So especially if you're training for a marathon, I think we can both imagine that running one would take a lot of energy. Neuroscientist Carlos Matute told me he's done 18 marathons, so he really knows it's exhausting. And he told me that he wondered, how do runners' bodies get the energy they need to make it to the finish line?
