You got it.
You can hear more of Juana Summers on Consider This, NPR's afternoon podcast about what the news means for you.
And for more science stories just like this one, follow Shortwave on whatever app you're listening to.
This episode was produced by Burleigh McCoy and Jordan Marie Smith.
It was edited by Rebecca Ramirez and Mallory Yu.
And I'm Angela Zhang.
Thanks for listening to Shortwave, the science podcast from NPR.
Short Wave · Could air pollution make your memory worse? · 16 Jun 2026 podcast
We're going to dive deep to whale graveyards, and then we're going to zoom in to ancient squirrel droppings, if you can believe that those words can even go together.
Yeah, you know what they say.
I mean, you know, you are what you eat, or at least poop out what you eat.
So the study I have for you today is about these really, really tiny particles of air pollution, like 30 times smaller than the width of a human hair.
And these particles are released by wildfires and car exhaust, among other things.
And they're bad for your heart and your lungs.
And they can also get directly to the brain through the blood.
That's Catherine Conlon, a study author.
She's a professor of epidemiology at the University of California, Davis.
She told me that semantic memory is how your brain stores information.
So let that New Delhi is the capital of India, or that three plus two equals five.
But including Black Americans in research, which is what the study did, means that solutions can hopefully reduce inequity.
Since they're almost twice as likely as white Americans to have dementia, and they're more likely to live in polluted or redlined neighborhoods.
