Short Wave Folgen

Short Wave producer Hannah Chinn has adult-onset eczema. They're not the only one. 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 sometimes?If you liked this episode, check out our episode on the science of itchiness. Also, follow us!

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? This is a shortened version of Joy and Kyle's live interview, moderated by Regina G. Barber, at this year's Library of Congress National Book Festival.If you liked this episode, check out our other episodes on facial recognition in Gaza, why AI is not a silver bullet and tech companies limiting police use of facial recognition.Interested in hearing more technology stories?

But how does the science driving that process show up in household batteries we use daily? Host Emily Kwong and former host Maddie Sofia talk battery 101 with environmental engineer Jenelle Fortunato.Want us to cover more science basics?
