Short Wave

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?
