Up to ten percent of people in the United States have it, according to the National Eczema Association — and its prevalence is increasing. Despite its ubiquity, a lot about this skin condition remains a mystery. So today, Hannah's getting answers. They sat down with Raj Fadadu , a dermatologist at UC San Diego, to ask: What is eczema? What triggers it in the first place? And might climate change make it worse some...
Sep 04, 2024•13 min•Ep 1125•Transcript available on Metacast Humans hallucinate. Algorithms lie. At least, that's one difference that Joy Buolamwini and Kyle Chayka want to make clear. When ChatGPT tells you that a book exists when it doesn't – or professes its undying love – that's often called a "hallucination." Buolamwini, a computer scientist, prefers to call it "spicy autocomplete." But not all algorithmic errors are as innocuous. So today's show, we get into: How do algorithms work? What are their impacts? And how can we speak up about changing them...

Aug 30, 2024•14 min•Ep 1122•Transcript available on Metacast At first glance, the whole narrative of aquatic invasive species may seem straightforward: A bad non-native species comes into a new ecosystem and overruns good native species. But the truth? It's a little more complicated. To tear down everything we thought we knew about invasive species and construct a more nuanced picture, host Emily Kwong talks to experts Ian Pfingsten , who works on the United States Geological Survey's Nonindigenous Aquatic Species Database , and Nicholas Reo , a Canada Ex...
Aug 28, 2024•13 min•Ep 1121•Transcript available on Metacast Human beings are hardwired for social connection – so much so that we think of even the most basic objects as having feelings or experiences. (Yup, we're talking to you, Roomba owners!) Social robots add a layer to this. They're designed to make us feel like they're our friends. They can do things like care for children, the elderly or act as partners. But there's a darker side to them, too. They may encourage us to opt out of authentic, real-life connections, making us feel more isolated. Today...

Emily and Regina break that and more of the week's news down with the help of All Things Considered 's Ailsa Chang . Read this study on digital switching and boredom in the...
Aug 23, 2024•9 min•Ep 1118•Transcript available on Metacast U.S. health officials now say COVID-19 is an endemic disease. That means it's here to stay – circulating fairly regularly like the flu. Even though that changes how public health officials think about managing the virus, they say it doesn't mean being less cautious or vigilant during surges, like the current one this summer. COVID still poses significant risks for older individuals and those with underlying conditions — and anyone who gets COVID is at risk of developing long COVID. NPR science c...

But there was one big set of objects that we skipped over: moons. So now we're back, with special guest, Radiolab 's Latif Nasser , to talk about yes, our moon — and the many moons and quasi-moons beyond it. Where did our Moon come from? How many moons are out there? What's this "quasi-moon" of which we speak and why is it "dancing" around space? Also, Latif tells us about Radiolab 's cont...
Aug 20, 2024•15 min•Ep 1116•Transcript available on Metacast For blind and low vision adults, the ability to read braille can be life-changing. Braille literacy is directly linked to higher rates of academic success and better employment outcomes for them. But there's a problem.

Aug 12, 2024•13 min•Ep 1111•Transcript available on Metacast We at Short Wave have been following all things Olympics, from the medals and new records to the ugly accusations that two women boxers aren't really women. Last year, the boxers failed gender tests, according to the International Boxing Association. The IBA claims the women have a "hormonal imbalance" that gives them women an unfair advantage. The International Olympic Committee has condemned these claims and defended the boxers' right to compete in the women's category. But this Olympics is fa...
