Synthetic peptides are getting some serious hype, from fitness influencers on your FYP to people seeking new options for chronic conditions. And while the human body already makes peptides, like insulin and the hormone oxytocin, most of the viral synthetic peptides are not approved by the Food and Drug Administration. Scientists say that raises some big concerns about safety and efficacy. So ahead of this week’s FDA meeting to discuss seven commonly used peptides, we get into the science with health reporter Sarah Boden.

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 joins host Nate Rott to talk about the outbreak – and how to protect yourself and your loved ones.

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.

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’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.

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. 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.

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, a science writer at The Atlantic, explains, that’s not the whole story. She and host Nate Rott also talk about how bats sip from the fountain of youth – and what it all may mean for humans.

In the age of AI, what differentiates humans from robots? What makes humans … human? To find answers, many people are studying consciousness: our capacity for experience. But doctors and researchers still have a long way to go when it comes to finding new ways to detect consciousness in humans — much less computer software. That gets especially tricky when people are unable to use their words or bodies to tell others whether or not they’re conscious, like in vegetative states. Today on Short Wave, how some researchers are finding ways to get around those limitations.

Maybe you’ve wondered about it late at night as a mosquito buzzes in your ear. Or when you kick over a rock and watch dozens of little critters crawl away: How many types of insects are there in the world? Scientists have been interested in answering this question for years. A new study — based on a census of tiny and, frankly terrifying, parasitoid wasps — suggests there’s way more than previously thought. Like, millions more that are just waiting to be discovered.

A valuable NASA satellite observatory is falling to Earth faster than scientists expected. It’s called the Neil Gehrels Swift Observatory, or “Swift” for short, and it can respond to celestial events much faster than its sky-gazing counterparts. To save Swift and test out a first-of-its-kind technology, NASA partnered with an Arizona-based startup to launch a refrigerator-sized robot, aptly named Link, into lower Earth orbit. That’s on its way right now to meet up with Swift to give it a boost.

Taking an air taxi to the airport may become as simple as ordering a ride share today. In our first episode in our summer series Tech Camp, we explore how a futuristic vehicle that transforms from helicopter to propeller plane is already taking flight in New York and San Francisco. This new kind of commuting might be here sooner than you think: A law just went into effect to build infrastructure for them in places like airports. Short Wave host Regina Barber speaks with the startup Joby and Georgia Tech aerospace experts about the safety, the science and what an actual ride would look like from app to air. Plus, we get into the history of the air taxis of the past and why those airlines no longer exist.
