One morning, Kyla Madonna Kenney woke up and her world was turned upside down: The room was spinning, she had a splitting migraine and one side of her body was shaking. Her tremors and migraine lasted for days. And for years afterwards, doctors would ask her: Did anything upset you recently? Are you stressed? Have you talked to a therapist about your anxiety? She underwent surgeries and took medications that were, in hindsight, unnecessary. It wasn’t until seeing Dr. David Perez, a neurologist who is also a psychiatrist, that she finally got the right treatment for her medical condition, functional neurological disorder. Today, we dig into this disorder – what it is, why it’s so unknown despite being a top reason people seek out neurologists and what this condition reveals about the consequences of siloing medicine.

We reeled in science reporter Ari Daniel for this episode who grants us three wishes in the form of three fishes. He takes us on a trip around the world to learn about how a clownfish in the western Pacific loses its stripes as it grows up just to fit in, a fat French fry of a fish that can scale a 50-foot rockface in the Democratic Republic of Congo, and the remarkable rearing of a pea-sized Pokémon-like fish at the Shedd Aquarium in Chicago. Together, these stories reveal just how remarkable and diverse these unassuming creatures are.

Ask any coffee aficionado, and they’ll tell you: A good cup is about more than the beans. The flavor is affected by lots of things – the roast and fermentation of the beans, the coarseness of the grind, the brewing temperature and even the chemicals in the water used to brew it. But there are very few quantitative ways to assess all the flavor variations. Current industry standards measure the concentration of coffee, but they often miss qualities like the acidity, brightness and fruitness. Scientists at the University of Oregon are trying to change that using a tool called a potentiostat that’s often used to measure the charge in batteries.

After the success of Artemis II, we at Short Wave definitely have moon fever. So, we brought NPR science correspondent Nell Greenfieldboyce onto the show to talk about where we’re headed. What will future Artemis missions look like and what needs to happen next for people to be able to walk on the moon again? We find out in this latest installment of Spacing Out – with space enthusiasts Regina G Barber and one of the hosts of All Things Considered, Scott Detrow!

To solar or not to solar? That is the question for this latest episode of our monthly series Nature Quest. For listener Darcey Hughes, installing solar panels isn’t just about keeping her utilities free of fossil fuels – it’s also a way to become fully self-reliant and save some money each month. But there’s a catch: She might have to chop down a large, shading cedar tree. Today, we investigate: When is solar worth it? And is it worth the price of an old, majestic tree? 

Do YOU have a question you have about your local environment? Send us a voice memo telling us your name, where you live, and your dilemma… we may make it the next Nature Quest. We’re reachable at [email protected].

When Karyn Paringatai learned about a pattern among her family members, it changed the course of her life: A lot of people died young. As Karyn dug into her family history, she learned many Maori families, like her own, suffered from a rare form of stomach cancer called diffuse gastric cancer. Sarah Zhang recently wrote a story on this kind of cancer as a staff writer at The Atlantic. Today, she gets into all the details with Short Wave host Emily Kwong: the mutation that causes it and the life-changing decision people with the mutation have to make – risk dying or get surgery to remove their entire stomach?

In the mid-1970s, primatologist Jane Goodall witnessed something that changed her opinion of chimpanzees forever: A four-year conflict amongst the chimpanzees she was studying in Tanzania. Chimpanzees that knew each other started killing each other. It was essentially the primate equivalent of a civil war. And now, it’s happening again: Fighting within the largest known community of chimpanzees. NPR science correspondent Nate Rott helps us break down what’s going on and what it could tell us about how human communities can fall apart.

Earth didn’t always have a moon. In the beginning of the solar system, when the planets were still forming, something happened that would change Earth’s night sky forever: The Moon was created!

How did it happen? This episode, co-host Regina G. Barber searches for answers with planetary scientists. With co-host Emily Kwong, they discuss how the moon was likely made, how scientists know and what that might mean for where Earth’s water came from.

Check out Regina's reporting on hydrothermal vents.

A previous version of this episode mischaracterized a scientific hypothesis. The episode incorrectly said the idea is that hydrothermal vents may have been the origin of water on Earth. In fact, the hypothesis is that life may have come from hydrothermal vents.

Eating disorders are complicated illnesses that skyrocketed among teenagers during the COVID-19 pandemic. Pediatrician Eva Trujillo says they "literally rewire the brain," decrease brain size, and make it harder to concentrate and to regulate emotions. Malnutrition can slow the metabolism, impact bone density and even lead to cardiac arrest. But Eva says, with the right treatment, people can also recover fully. She's the president of the International Association of Eating Disorder Professionals and co-founder of Comenzar de Nuevo, a leading treatment facility in Latin America. Today on the show, host Emily Kwong talks about the physical and mental impacts of eating disorders with Dr. Trujillo and Moorea Friedman, a teen mental health advocate and host of the podcast Balancing Act. Plus, how to recover in a world steeped in diet culture. (encore)

For residents of Prek Touch, Cambodia — right on the banks of the Mekong River — flooding is a regular part of life. But as those floods worsen due to climate change, it’s getting harder to adapt. Along with other flood-prone regions throughout Southeast Asia, government officials are facing an issue: how to deliver widespread weather warnings in a timely, effective way. One solution that’s working for Prek Touch? Voicemails. Today on the show, NPR climate correspondent Rebecca Hersher explains how a simple phone alert can prompt preparation, increase evacuation, and save lives.
