Three weeks ago, U.S. Secretary of the Interior Doug Burgum shared an unusual tweet: a cartoon image of himself with his arm draped around a giant, anthropomorphized lump of coal. This piece of coal has big googly eyes and a smudge of a nose, and is wearing a safety vest and a hard hat. He is, frankly, adorable—and he has a name: Coalie.

When Coalie first appeared on the internet, he went viral—ridiculed on social media, in newsletters, and even on late night talk shows. And that’s because this big-eyed, cute piece of coal was widely understood to be coal propaganda, a tool to soften the coal industry’s image.

But the truth about Coalie is more complicated. His origins tell a story about what it’s like for federal employees to try to do their work while navigating the Trump administration’s agenda. Coalie may be widely seen as a mascot for coal mining, but that’s not what he was made for.

In this episode, you’ll hear from Simone Randolph, Director of Communications for the Office of Surface Mining Reclamation and Enforcement (OSMRE); Sara Eckert, formerly of OSMRE; Slate staff writer Nitish Pahwa; and Leah Stokes, who researches climate and energy policy at the University of California, Santa Barbara and co-hosts the podcast A Matter of Degrees.

Thank you to Daniel Raimi, Tony Ho Tran, and Hannah Northey.

It’s a weird time for culture. There is more of it than ever before, it’s more accessible than ever before, but so little of it feels original. New movies are based on old stories, new songs are recycling old hooks, and fashion trends are cycling so fast that everything’s in. 

Has our culture grown stagnant? The author and culture critic W. David Marx thinks so. 

His new book, Blank Space, argues that there is a “blank space” in the 21st century where cultural innovation should be. In this episode, David explains to Willa how culture change worked in the 20th century, what changed after the turn of the millennium, and what we might do about it.

We are really lucky to get lots of listener suggestions for the show, more good questions than we can possibly answer in a mailbag episode once or twice a year. So we’re starting a new segment we call… Decoder Rings Back! Every month, host Willa Paskin will personally call up a listener to answer their question. 

In this inaugural installment of Decoder Rings Back, Willa calls up listener Dustin Malek about his cultural mystery: Why did the Mona Lisa, of all paintings, become the most famous in the world, bar none? Willa shares the story of daring heist that turned Leonardo da Vinci’s enigmatic smiling subject into a celebrity.

Future episodes of Decoder Rings Back will only be available to Slate Plus subscribers. So if you want to be sure not to miss them, sign up for Slate Plus! You’ll get exclusive episodes and ad-free listening not just on our show, but all your favorite Slate podcasts. Subscribe from the Decoder Ring show page on Apple Podcasts or Spotify, or visit slate.com/decoderplus for access wherever you listen.

Decoder Ring listeners write in with some excellent mysteries, and for our last episode of the year we’re solving three of them. Why do children play in boxes full of sand? Why do rock bands pretend like the show is over when everybody knows they’re coming back for an encore? And what was up with those school assemblies where you’d get to skip class to learn about…yo-yos?

The voices you’ll hear in this episode include yo-yo masters ”Dazzling Dave” Schulte and Dale Oliver, children’s book author Rob Peñas, Pulitzer Prize-winning design critic Alexandra Lange, and music journalists Brian Wise, Michael Walker, and Travis Andrews. 

You can find all the music from the segment about encores in this YouTube playlist.

Videomate: Men was a VHS tape released in 1987 featuring 60 single men pitching themselves as dates to women on the other side of the TV screen: “The love of your life could be on your TV tonight!” the box reads. In retrospect, Videomate: Men is a bizarre and hilarious time capsule, but at the time it was one of many manifestations of what was known as video dating. To find out how anyone thought this was a good idea, Decoder Ring examines the weird and forgotten world of video dating in the 1970s, ’80s, and ’90s to find out why video dating once seemed like the future—and if that future is still yet to come.

On this episode, originally released in 2019, we talk to the creators of the Found Footage Fest, VHS collectors who unleashed Videomate on the internet; ask the creators of video dating services like Videomate’s Steve Dworman and Great Expectations’ Jeffrey Ullman what they were thinking; and talk to participants who used these services but not necessarily in the way that was intended. We’ll also discuss the future of video dating with Coffee Meets Bagel co-founder Dawoon Kang and former host of The Longest Shortest Time Andrea Silenzi.

This episode was written by Willa Paskin and was produced and edited by Benjamin Frisch. We had research assistance from Cleo Levin. Decoder Ring is produced by Katie Shepherd, Max Freedman, and Evan Chung, our supervising producer. Merritt Jacob is Senior Technical Director.

Americans are currently besotted with protein. It’s touted as being good for muscle growth, weight loss, skincare, mental acuity, longevity, and much else besides. It’s sold to men, women, children, the elderly— you can even buy protein for your pets. The protein supplement market alone is worth $21 billion and growing—and extra protein is being added to coffee, cereal, pasta, beer, ice cream, and popcorn.

But as frenzied as we currently are about protein, this is not the first protein boom—or even the second. Protein has been promoted as a charismatic, cure-all nutrient for nearly two centuries. In this episode, with the help of Samantha King and Gavin Weedon, the authors of Protein: The Making of a Nutritional Superstar, we look closely at all our protein crazes and their associated protein products—from beef tea to whey powder—and see what they can tell us about our current protein mania. 

This episode was produced by Max Freedman. Decoder Ring is also produced by Willa Paskin, Katie Shepherd, and Evan Chung, our supervising producer. We had editing support from Josh Levin and fact-checking by Sophie Summergrad. Merritt Jacob is Senior Technical Director.

Autumn may have more cozy signifiers than any other season—though we all have our own favorites. Maybe for you it’s sweater weather, football games, spooky season, apple picking, leaf peeping, or mainlining candy corn. Whatever it is, in today’s episode we’re looking closely at three of these autumnal staples.

First, we get to the bottom of a recurring complaint about the taste of the pumpkin spice latte. Then we gaze deep inside the enigma hiding inside colorful fall leaves. Finally we ask some hard-hitting questions about the seasonal availability of an elusive cookie. Snuggle up and enjoy!

In this episode, you’ll hear from author and podcaster Don Martin who has a new audiobook out about loneliness called Where Did Everybody Go?. We also speak with Simcha Lev-Yadun, professor of botany and archeology; Susanne Renner, botanist and honorary professor of biology at Washington University in St. Louis; and Prospect Park Alliance arborist Malcolm Gore. And you’ll also hear from Lauren Tarr, who runs the blog Midlife Moxie and Muscle, and her mother Grace Dewey, along with Caroline Suppiger, brand manager at Mondelēz.

There’s a ubiquitous prop in just about every police procedural and conspiracy thriller: a cork board pinned with documents, newspaper clippings, and Polaroid photos, all connected by a web of red string. They go by many names, including pin boards, string boards, evidence boards, investigation walls, conspiracy walls, and walls of crazy. These boards can be vehicles of insight or manifestations of madness—and in many cases, both. But where did they come from? And can they really solve a crime?

In this episode, we try to unwind the red string board all the way to its center. To aide in our investigation, we enlist the help of Aki Peritz, a former CIA analyst and the author of Disruption: Inside the Largest Counterterrorism Investigation in History. You’ll also hear from Shawn Gilmore, editor of The Vault of Culture and creator of the Narrative String Theory project; and Dr. Anne Ganzert, author of Serial Pinboarding in Contemporary Television. And we learn about the intricacies of building a string board from production designers Michael Scott Cobb (It’s Always Sunny in Philadelphia) and John D. Kretschmer (Homeland).

This episode was written and produced by Evan Chung, Decoder Ring’s supervising producer. It was edited by Willa Paskin. Decoder Ring is also produced by Katie Shepherd and Max Freedman. Merritt Jacob is Senior Technical Director.
