Slow Burn

In New Jersey, the tomato is king. Almost a century ago, a scientist at Rutgers University developed a variety that became the tomato that lined grocery store shelves for decades. Now, Rutgers scientists are at it again—they’ve invented a new grape tomato called Scarlet Sunrise. Will it become the next hot item in the produce aisle? How do you even invent a new tomato? And why are new varieties of fruits and veggies becoming more popular than ever? This week, Decoder Ring presents an episode from The Sporkful in collaboration with Planet Money that aims to find out. In it, Dan Pashman and Kenny Malone investigate these grocery store mysteries, and see if this hot new tomato can win over a longtime grape tomato skeptic.

From Planet Money, this episode was produced by James Sneed, edited by Keith Romer, fact checked by Sierra Juarez, and engineered by Cena Loffredo and Jimmy Keely. The Sporkful production team includes Dan Pashman, Emma Morgenstern, Andres O'Hara, Kameel Stanley, and Jared O'Connell.

Since Bram Stoker’s Dracula was first published in 1897 it has inspired hundreds, if not thousands, of other fictional vampires. But none are quite as strange as that found in the frigid climes of Iceland. There, just a few years after Dracula was first printed, emerged a so-called translation that diverged so radically from Stoker’s that it introduced new characters, new scenes, and new themes—and yet seemed to have been published with Stoker’s blessing. People have since spent years trying to figure out how exactly this Nordic Dracula came to be—and who its true author is. It all makes for a seasonally appropriate literary mystery—one full of doppelgängers, supervillains, plot twists, and vampires who just refuse to die.

In this episode, you’ll hear from Ásgeir Jónsson, literary enthusiast and Governor of the Central Bank of Iceland; Helen Zaltzman, host of The Allusionist podcast; Icelandic publishing scholar Kristján B. Jónasson; publisher Rickard Berghorn; and Benjamin Mier-Cruz, Assistant Professor of Scandinavian Studies and Gender and Women’s Studies at University of Wisconsin-Madison.

Clowns have existed in various forms for thousands of years. From the big top to Bozo’s TV show, they used to be beloved figures of amusement and delight. What changed and made so many people suspect and fear them? In this episode, originally aired in 2018, Decoder Ring traces the history of clowns and clowning and finds that both the scary clown and the happy clown are over-simplifications that have more in common than it might first appear.

This episode was produced and edited by Benjamin Frisch. Decoder Ring is produced by Max Freedman, Alesandra Tejeda, and Evan Chung, our supervising producer. Merritt Jacob is Senior Technical Director.

Few inspirational phrases are quoted more often than Mahatma Gandhi’s “Be the change you want to see in the world.” It shows up on t-shirts, bumper stickers, even tattooed on people’s bodies. Life coaches, leadership trainers, and American presidents constantly cite it. There is one problem with this quotation, however: Gandhi never said it. And the story of how the “be the change” actually came to be—according to its true originator—is stranger, more intricate, and more astounding than you could ever expect.

In this episode, Decoder Ring’s Evan Chung speaks with Arleen Lorrance, the former Brooklyn high school teacher who actually brought “be the change” into the world in the 1970s. The surprising tale she has to tell involves grindhouse cinema, cosmic rays of light, and Vice President Al Gore. You’ll also hear from Diane Kennedy Pike, whose marriage to the controversial Bishop James Pike plays a pivotal and unexpected role in turning the quote into the inescapable maxim it is today.

This episode was written and produced by Evan Chung, Decoder Ring’s Supervising Producer. It was edited by Willa Paskin and Max Freedman, who also produce the show. Merritt Jacob is Senior Technical Director. Special thanks to Keith Akers.

In the early 1970s, a jigsaw puzzle of a cheerful, young, naked, fat woman known only as “Bridget in the Buff” arrived in stores all over America. It was just the first of countless Bridget-related merchandise that would be sold around the world for the next decade: calendars, playing cards, coloring books, cookbooks, and much more. Bridget was everywhere. But who was she?

In this episode of Decoder Ring, the real Bridget reveals all. Her name is Dawn Brooks, and she takes us through the unusual path that led her to pose nude for scores of popular products. How does it feel to be a gag gift—and now, an unlikely icon?

Besides Dawn, you’ll hear from her friends Leslie Block Prip, Kathy McDermott, and John Emery; Herb Kavet, whose company created the “Bridget in the Buff” line of products; and Bridget admirers Laura Mazzuca Toops and Ginger Geralamo.

Podcasts are everywhere. They’re more popular and influential than they’ve ever been. But at the same time, what makes a podcast a “podcast” has never been more confusing.

Until recently, the definition of “podcast” was clear: audio distributed over the internet. A podcast was something you listened to, not something you watched. But now, almost all of the most popular podcasts have video, too. And most of these podcasts share a video-friendly format: two or three people chatting behind big bulky microphones.

You may have noticed that our podcast, Decoder Ring, does not have video, so these developments have given our team, like many other podcast-makers, no shortage of anxiety. In this week’s episode, we’re embracing our inner chatcast: host Willa Paskin and supervising producer Evan Chung trace the history and evolution of podcasting through their own histories with the medium, and wrestle with their complicated feelings about the state of the format in 2026.

This episode was produced by Max Freedman. Merritt Jacob is Senior Technical Director. Our intern is Phoebe Mulder. Video production by Micah Phillips. Special thanks to Amanda Dobbins, Leon Neyfakh, Nick Quah, Ben Richmond, Amber Robinson, Susan Matthews, Mary Harris, and Mia Lobel.

McGruff the Crime Dog arrived on the scene at the dawn of the 1980s, just as a firehose of anti-drug PSAs was inundating the youth of America. These messages didn’t always work as intended—but they did work their way into the long term memories of the kids who heard them.

In the second episode of our two-part series, originally released in 2022, on the weird world of PSAs and very special episodes, we look at how McGruff’s Smart Kids Album influenced everything from straight edge hardcore to a couple’s wedding playlist. We’ll hear from Sarah Hubbard, Daniel Danger, Joseph Cappella, David Farber, Mike Hawes, Robin Nelson, Daisy Rosario, and Tatiana Peralta.

This episode was written by Willa Paskin, and produced by Willa Paskin and Katie Shepherd. It was edited by Jamie York. Decoder Ring is produced by Max Freedman and Evan Chung, our supervising producer. Merritt Jacob is Senior Technical Director. Our intern is Phoebe Mulder.

In the first of two episodes, originally released in 2022, we take a look at PSAs and their strange afterlife through the lens of a trench-coat wearing bloodhound and his bizarre, yet catchy anti-drug songs. We’ll talk to Dan Danger, Sherry Nemmers, Joseph Cappella, David Farber, Mike Hawes, and Robin Nelson to discover how the McGruff Smart Kids Album came to exist in the first place.

The sun has always been a hot topic. For centuries, we’ve flip-flopped over whether our health depends on soaking up its rays—or shielding ourselves from them. The current conventional wisdom is clear: Avoid sunburns at all costs, using shade, hats, long sleeves, and the highest SPF sunscreen your drugstore has to offer.

But in a historical sense, that advice is pretty new. Not long ago, doctors told parents to slather babies in oil and let them roast in the afternoon sun. Tanning was once medically prescribed. Though we’ve lived under it for all of human history, we’ve never quite figured out how much sun is actually good for us. So where has the pendulum landed today? And why does it keep swinging in the first place?

In this episode of Decoder Ring, Willa talks to Rowan Jacobsen, author of the new book In Defense of Sunlight: The Surprising Science of Sun Exposure, who argues that our current guidelines have gone too far in emphasizing the risks of the sun. She also speaks with Catherine Cocks, the director of the Syracuse University Press and author of Tropical Whites: The Rise of the Tourist South in the Americas, about how race drove our cultural obsession with suntanning.

This episode was written by Willa Paskin and our supervising producer, Evan Chung, who also produced this episode. Decoder Ring is also produced by Max Freedman. Merritt Jacob is Senior Technical Director. Our intern is Phoebe Mulder.

Most of us use GPS—the Global Positioning System—on a daily basis: to find our location when we’re driving, running, shopping, dating, and so much more. But GPS is even more important, and more vulnerable, than you think.

In the last few years, GPS interference has been reported all over the world, from war zones to shipping routes to public squares. What was once the fanciful plot of a Bond movie—bad guy manipulates GPS to start World War III—is increasingly plausible. How did the world come to rely so heavily on such an unreliable system?

In this episode of Decoder Ring, host Willa Paskin talks to journalist Katherine Dunn, author of the new book Little Blue Dot: How GPS Shaped the Modern World. You’ll learn how GPS works, why it was created, how it became so ubiquitous, and why it’s now under attack. You’ll also hear from Dr. Todd Humphreys, an aerospace engineer who manipulated GPS to trick an $85 million superyacht into following his direction—for science, of course.
