Cyclosporiasis: the science, risks and red flags

What’s small, round and could give you explosive diarrhea? Cyclospora parasites. The diarrheal disease they cause is wreaking havoc on thousands this summer in what is the largest known flare up in the U.S. ever. What’s causing it and what can we do about it? NPR’s Joseph Kim [https://www.npr.org/people/g-s1-127759/joseph-kim] joins host Nate Rott [https://www.npr.org/people/348779465/nathan-rott] to talk about the outbreak – and how to protect yourself and your loved ones.

Are Trump and AI driving a nuclear power boom?

A race started by President Trump is leading to the rapid construction of new, experimental nuclear reactors. If they work, they could power data centers for artificial intelligence. But critics worry that the breakneck pace is compromising safety and public trust. NPR correspondent Geoff Brumfiel talks about the potential risks and benefits, and whether this may lead to a new nuclear age.

Why did designing the World Cup pitches take eight years?

Yamal and Messi aren’t the only stars of the World Cup finals. If you’ve been watching any of the games, you’ve probably stared directly at a huge, unsung hero: the turf. Turf grass science is a real thing, and it’s John Sorochan [https://utia.tennessee.edu/person/?id=4020]’s area of expertise. He’s a scientist at the University of Tennessee at Knoxville, and he’s spent the last eight years preparing for the grass pitch the players are scoring on. John had the daunting task of figuring out how to create consistency and uniformity across all the World Cup stadiums. That meant dozens of team base camps and 16 different stadiums where turf had to weather all kinds of conditions – from Mexico City’s high altitude, to Miami’s sweltering heat. Today on Short Wave, we dive into the science behind it all.  Interested in more science behind your favorite sports? Email us your question at shortwave@npr.org [shortwave@npr.org].

Our favorite brains, including Einstein's stolen one

At Short Wave, we love a good brain. Which is why we’ve had a lot of conversations over the years with NPR’s neuroscience reporter, Jon Hamilton [https://www.npr.org/people/2100615/jon-hamilton]. Jon’s been writing about brains for over 15 years, from tiny brain organoids that grow in a dish, to fruit fly brains, mouse brains and some really memorable human brains. But Jon is retiring, so today on the show he joins us to share the most memorable brains he’s come across in the past couple of decades.  Interested in more brain science?

What's this super-aging butterfly’s longevity secret?

What if there were a great ape species that could live over 1,000 years? That’s basically Heliconius in the butterfly world. The insects live around 25 times longer than their butterfly cousins, and scientists think they have one clue as to why: pollen. But as Katie Wu [https://www.theatlantic.com/author/katherine-j-wu/], a science writer at The Atlantic, explains, that’s not the whole story. She and host Nate Rott [https://www.npr.org/people/348779465/nathan-rott] also talk about how bats sip from the fountain of youth – and what it all may mean for humans. Read Katie's full story here [https://www.theatlantic.com/science/2026/06/butterflies-longevity/687556/].
