Hey, Short Wavers! Today, we have a special present for all of you: An episode from our good friends at NPR's Body Electric podcast all a bout artificial intimacy! Thanks to advances in AI, chatbots can act as personalized therapists, companions and romantic partners. The apps offering these services have been downloaded millions of times. If these relationships relieve stress and make us feel better, does it matter that they're not "real"? On this episode of Body Electric, host Manoush Zomorodi talks to MIT sociologist and psychologist Sherry Turkle about her new research into what she calls "artificial intimacy" and its impact on our mental and physical health.

Last year, a dog named Bunny went viral on TikTok for pressing buttons with words on them to "communicate" with her owner. But can dogs even understand those words on a soundboard in the first place? A new study in the journal PLOS One [https://journals.plos.org/plosone/article/comments?id=10.1371/journal.pone.0307189] seeks answers. Host Regina G. Barber and producer Rachel Carlson break down that story and more of the week's news with the help of All Things Considered's Ari Shapiro.

Short Wave producer Hannah Chinn [https://www.npr.org/people/g-s1-4958/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 [https://med.stanford.edu/profiles/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 [https://www.npr.org/2023/09/25/1198908044/itch-hives-eczema-scratch].

Humans hallucinate. Algorithms lie. At least, that's one difference that Joy Buolamwini [https://www.unmasking.ai/] and Kyle Chayka [https://www.newyorker.com/contributors/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.

Just in time for the return of the school year, we're going "Back To School" by revisiting a classic at-home experiment that turns lemons into batteries — powerful enough to turn on a clock or a small lightbulb. 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?
