Radiolab

In the early 2000s, Sunil Nakrani felt stuck. 
Back then, websites crashed all the time. When Sunil noticed this, he decided he was going to fix the internet. But after nearly a year of studying the architecture of the web, he was no closer to an answer. In desperation, Sunil sent out a raft of cold emails to engineering professors. He hoped someone, anyone, could help him figure this out. Eventually, he learned that the internet could only be fixed if he paid attention to the humble honeybee. 
This is the story of the Honeybee Algorithm: How tech used honeybees to build the internet as we know it.
Special thanks to John Bartholdi, John Vande Vate, Sammy Ramsey, James Marshall, Steve Strogatz, Duc Pham, and Heiko Hamann.
We found out about this story thanks to our friends at AAAS, who run the one and only Golden Goose Awards. The award goes to government funded science that sounds trivial or bizarre, but goes on to change the world. The Honeybee Algorithm won a Golden Goose Award back in 2016 (https://zpr.io/ePxaaYja6YF4). Thank you to our friends there: Erin Heath, Gwendolyn Bogard, Valeria Sabate, Joanne Padron Carney, and Meredith Asbury.

The Wisdom of the Hive: The Social Physiology of Honeybee Colonies (https://www.hup.harvard.edu/books/9780674953765) by Thomas D. Seeley (1995, Harvard University Press)
Piping Hot Bees & Boisterous Buzz-Runners: 20 Mysteries of Honey Bee Behavior Solved (https://zpr.io/tNDqkw372Rhr) by Thomas D. Seeley
And, Paths of Pollen (https://zpr.io/cqRPpAdGRwMi) by Stephen Humphrey. One of our former transcribers who we recently learned had hidden talents far beyond the invaluable work they did for us. This book is only tangentially related to the content in the episode, but super cool in its own right.

In this episode, we break the thermometer and watch the mercury spill out as we discover that temperature is far stranger than it seems. We first ran this episode in 2021: Five stories that run the gamut from snakes to stars. We start out underwater, with a species of snake that has evolved a devious trick for keeping warm. Then we hear the tale of a young man whose seemingly simple method of warming up might be the very thing making him cold. And Senior Correspondent Molly Webster blows the lid off the idea that 98.6 degrees Fahrenheit is a sound marker of health.

One spring evening in 2024, a science journalist named Rachel Gross bombed at karaoke. The culprit was a bleed in a fist-sized clump of neurons tucked down in the back of her brain called the cerebellum. A couple weeks later, her doctors took a bit of it out, assuring her it was just helping her with motor coordination — she might be a bit clumsy for a while, but she’d still be herself. But afterwards, she didn't feel like herself. So she dove into the dusty basement of the brain (and brain science) to figure out why. What Rachel found was a burgeoning new frontier in neuroscience. We learn what singing Shakira on stage has to do with reaching for a cup of coffee — and how the surprising relationship between the two is making us rethink what we think about thinking.

Gross, Brittany Aguilar, and, of course, Shakira.

Most of us spend some part of our lives feeling bad about ourselves and wanting to feel better. But this preoccupation is a surprisingly new one in the history of the world, and can largely be traced back to one man: a rumpled, convertible-driving California state representative named John Vasconcellos who helped spark a movement that took over schools, board rooms, and social-service offices across America in the 1990s. This week, we look at the rise and fall of the self-esteem movement and ask: is it possible to raise your self-esteem? And is trying to do so even a good idea?
Special thanks to big thank you to the University of California, Santa Barbara Library for use of audio material from their Humanistic Psychology Archives and to their staff for helping located so many audio recordings.

This episode, first aired in 2019, brings you the story of John Scott, the professional hockey player that every fan loved to hate.  A tough guy. A brawler. A goon. But when an impish pundit named Puck Daddy called on fans to vote for Scott to play alongside the world’s greatest players in the NHL All-Star Game, Scott found himself facing off against fans, commentators, and the powers that be.  Was this the realization of Scott’s childhood dreams? Or a nightmarish prank gone too far? Today on Radiolab, a goof on a goon turns into a parable of the agony and the ecstasy of the internet, and democracy in the age of Boaty McBoatface.
Special thanks to Larry Lynch and Morgan Springer.
