The origins of celebrity, from medieval divas to Kris Jenner

From Joan of Arc to Kim Kardashian, and Davy Crockett to Donald Trump, celebrity culture has deep and wide roots. Famous people who elicited Kardashian-level feelings of love and hate in the public were present centuries ago — long before screens and social media. Though, as we find out in this podcast, they all share similar qualities. *This episode originally aired on June 30, 2022. Irina Dumitrescu is a writer, co-host of the LRB podcast Encounters with Medieval Women, and a professor of Medieval English at the University of Bonn. Sharon Marcus is author of The Drama of Celebrity and the Orlando Harriman Professor of English and Comparative Literature at Columbia University.

Why there's no place like Oz

Even if you aren't a fan of Frank L. Baum's The Wonderful Wizard of Oz, you know about the Tin man, the ruby red shoes and that the dog is named Toto. The classic story was an instant bestseller in 1900 and its popularity is still going strong with not one but a two-part prequel. For over 125 years, there have been derivative works of Oz, from Broadway musicals, films, comic books and more. IDEAS follows the proverbial yellow brick road to uncover how this seemingly simple story of friendship, self reliance and longing for home continues to speak to us. *This episode originally aired on Sept. 9, 2025. If this episode has left you curious about Matilda Joslyn Gage, the suffragist who was a big influence on Frank L. Baum's feminism, listen to this podcast. There's a reason you likely have never heard of her.

What does it mean for a river to be ‘alive’?

Renowned natural history writer Robert Macfarlane traveled to Ecuador, India and Quebec, pondering the question of whether rivers are living beings — the premise behind much of the movement to legally recognize the rights of nature. He found that the answer to that question is more complicated and wondrous — and more life-altering and world-changing — than he could have imagined. *This episode originally aired on Sept. 3, 2025.

How dandelion seeds take flight, and more…

In a study inspired by a field of dandelions, researchers wanted to know why, when you blow on a dandelion seed head, only the seeds closest to you take flight. They found that a dimple in the seed heads where the seed attaches is larger on one side than the other, and that the seeds consistently broke off from the smaller side of that dimple. Once they take flight, each dandelion seed uses its unique shape to catch a ride on the wind.
