  • Climate Change Is Here For Your Chocolate

    Climate Change Is Here For Your Chocolate
    Aug 1 2025
    Last year, we reported how extreme weather events may be dwindling the future of chocolate. Just last week, we saw an inkling of that: The Hershey Company announced it would significantly raise the cost of its candy in the face of historically high cocoa prices. So, we're revisiting host Emily Kwong's conversation with Yasmin Tayag, a food, health and science writer at The Atlantic. They get into the cocoa shortage: What's causing it, how it's linked to weather and poor farming conditions and what potential solutions exist. Plus, they enjoy a chocolate alternative taste test.

  • Why Illusions Are A Brain Feature, Not A Bug

    Why Illusions Are A Brain Feature, Not A Bug
    Jul 30 2025
    A grayscale ballerina who appears to be moving. A human who can fit in a doll box. A black-and-white prism that appears to change shape when viewed from three different directions. Those are the top winners of the 2024 Best Illusion of the Year Contest, open to illusion makers around the world and co-created by neuroscientist Susana Martinez-Conde. Today on the show, we get lost in the magic and science of visual illusions.

  • Nature Quest: Are Summers Getting Hotter?

    Nature Quest: Are Summers Getting Hotter?
    Jul 29 2025
    Much of the country is deep in the middle of a heat wave right now. And every summer, Duane Stilwell's town in Arizona seems to get hotter. It has him worried — and he's not the only one. Since 1980, the average number of heat waves in the U.S has doubled and the average length of a heat wave season has increased from 40 days to 70. Future summers, experts say, will be even hotter. But why exactly is that happening, and what can people do to protect themselves from the heat?

    This episode is part of Nature Quest, a monthly segment that answers listeners' questions about their local environment. If you have a question, send a voice memo to shortwave@npr.org that includes it, your name and where you live. We might make it into our next Nature Quest episode!
