Harvard students AnhPhu Nguyen and Caine Ardefyio modified Meta's smart glasses so that you can search someone's face quickly, almost without them knowing, and pull up personal internet...

 Note: This episode describes sexual situations that are non-consensual.

Sharing a photo of yourself online has always carried some risk. But things got a lot scarier this year when users began using Grok, X's generative AI chatbot to create sexualized deepfakes of women and children. Iona Fyfe, Scottish folk singer and activist, was one of the people who had an image altered and manipulated by Grok. Hosts Ben Brock Johnson and Am...

And "baby, it's good and nice."

In the 1980s, a moral panic swept across America. Parents, prosecutors, and talk show hosts became convinced that devil worshippers were hiding in plain sight, abusing children at daycares, performing ritualistic sacrifices, and corrupting the innocent.

In 1970, a young biologist named David Mech published what could be the most consequential book on wolves ever written. At the time, The Wolf: The Ecology and Behavior of an Endangered Species, was the most complete collection of scientific knowledge on wolves money could buy, and it became best seller for Dave's publishers. But outside of the world of wolf biology, the book is also credited with unleashing a certain ...

Fast-and-cheap shipping is now foundational to the American way of life, thanks in large part to Amazon Prime. Still, when producer Grace Tatter sees a video of a man claiming that he's continuously ordering and returning an 110-pound anvil from Amazon with no repercussions from the tech giant, she has questions. Is this legit, or is it a Wile E. Coyote-level scheme? Unlike an anvil, the answer can't be found online.

    Adam Aleksic's Roman Empire is language, particularly how algorithms are changing the way we all use words. This week, Endless Thread gets algospeak-pilled and learns how "unalive" spread from a kids' Spider-Man cartoon to TikTok mental health communities trying to avoid censorship; what we're really saying when we say we're "goblin-core," and whether this all means we're "cooked."

    Who gets credit for starting a meme? Usually... nobody — they're made too quickly and organically. In the case of one of the most famous bait-and-switch memes of all time, the "Rick Roll," we may be looking at something experts call convergent evolution. Did the Rick Roll originate with a piece of code on the message board 4Chan, or with a prank call to a local sports show in Michigan? And why does the Rick Roll have such staying p...

    2025 marks 20 years of Google Maps — a tool that many of us would be, quite literally, lost without.

    We hear from New Orleanians who used Google Maps/Google Earth in its inaugural year to survey the damage to their homes following Hurricane Katrina.

    We also talk to the internet's Map Men, who ask whether "the best maps humanity has ever produced are simultaneously the worst maps for humanity?" in their new book, "This Way Up: Whe...

    There's a lot of drone warfare footage on the internet from Ukraine and Russia. But over the last year, a surprising change has emerged, via photos from the battlefront posted online. It has become clear that a huge part of the drone war, from dropping grenades on soldiers in bunkers, to dropping explosives on infrastructure or airfields, is wired. Those wires are fiber optic cable, stretching from drone operators to the drones, wh...

    The internet decides what's for dinner.

    Ruby Tandoh is the author of the new book, All Consuming: Why We Eat the Way We Eat Now. A stint on the Great British Bake Off when she was in college launched her into the world of cookbooks — increasingly irrelevant in a world where we're more likely to turn to Google for a recipe than turn to our bookshelves — and provided her an education in how pop culture stokes our cravings. She takes...

      Saskia Inwood woke up one morning, knowing her life would never be the same. The night before, she learned the unimaginable – that the husband she knew in the light of day was a different person after dark. This season unpacks Saskia’s discovery of her husband’s secret life and her fight to bring him to justice. Along the way, we expose a crime that is just coming to light. This is also a story about the myth of the “perfect victim:” who gets believed, who gets doubted, and why. We follow Saskia as she works to reclaim her body, her voice, and her life.
