    Neither Confirm Nor Deny

    17/07/2026 | 29 mins.
    In an episode we first ran back in 2019, we explore how a sunken nuclear submarine, a crazy billionaire, and a mechanical claw gave birth to a phrase that has hounded journalists and lawyers for 40 years and embodies the tension between the public’s desire for transparency and the government’s need to keep secrets.  

    Whether it comes from government spokespeople or celebrity publicists, the phrase “can neither confirm nor deny” is the perfect non-denial denial. It’s such a perfect deflection that it seems like it’s been around forever, but reporter Julia Barton takes us back to the 1970s and the surprising origin story of what’s now known as a “Glomar Response.” With help from David Sharp and Walt Logan, we tell the story of a clandestine CIA operation to lift a sunken Soviet submarine from the ocean floor and the dilemma they faced when the world found out about it. It’s an episode we first released in 2014, but given some things in the news recently, it resonated with us again.

    In the 40 years since that operation, the Glomar Response has become boilerplate language from an array of government agencies. With help from ProPublica editor Jeff Larson and NPR’s Dina Temple-Raston, we explore the implications of this ultimate information dodge. ACLU lawyer Jameel Jaffer explains how it stymies oversight, and we learn that, even 40 years later, governmental secrecy can be emotionally painful.

    More information about Glomar:

    After 40 years, many of the details of Project Azorian are only now coming to light. The US government’s default position has been to keep as much of it classified as possible. It took three years for retired CIA employee David Sharp to get permission to publish his account of Project Azorian. And FOIA played an indirect role in that, as Cold War historians got the CIA to release, in redacted form, an internal history of the mission. After that and a threat of legal action, Sharp was finally able to publish his manuscript in 2012.

    We mentioned conspiracy theories that have swirled around Project Azorian filling the void where official silence has reigned. One of them is promulgated in the 2005 book “Red Star Rogue” by Kenneth Sewell and Clint Richmond. They posit that the K-129 was taken over by rogue Stalinist KGB agents in order to start a nuclear conflict. But the conflict was to be between the US and China, as, according to the authors, the sub had powers to disguise its sonic signature as a Chinese Navy vessel.

    This book is the basis of the 2013 drama “Phantom,” which features Ed Harris and David Duchovny as Soviet military officers who sip vodka in a very un-Russian way.

    Russian Naval historians, like Nikolai Cherkashin, are not only insulted by this take on the cause of the K-129’s demise, they say the true cause is much easier to pinpoint: They say an American vessel, possibly the USS Swordfish, collided with the Soviet submarine.

    Despite the fact that the US government has turned over many documents about Project Azorian and what it found to the Russian government, many in the Russian Navy stand by their theory that it was far too easy for the US to locate the K-129 on the bottom of the Pacific, given the technology of the time. According to these theories, Project Azorian was nothing more than an elaborate cover-up disguised as ... an elaborate cover-up. We can neither confirm nor deny that we exactly understand how that would have worked in practice or execution.

    It’s one of the more solemn moments of the Cold War, and one that the Glomar Response helped keep a secret for a very long time.

    The Holy Shiver

    10/07/2026 | 37 mins.
    Lauren Brown gets goosebumps. A lot. Sometimes several times a day. When her partner, writer Carmen Maria Machado, noticed it...she couldn't stop thinking about it. Why does she get them in so many different situations? What’s happening in her body and what does it mean? We take that question and run with it. We face chilly winds, sudden frights, and moments when the world seem to shift under your feet to figure out what the little bumps on our skin might be trying to tell us.

    Atomic Artifacts

    03/07/2026 | 40 mins.
    Back in the 1950s, facing the threat of nuclear annihilation, federal officials sat down and pondered what American life would actually look like after an atomic attack. They faced a slew of practical questions like: Who would count the dead and where would they build the refugee camps? But they faced a more spiritual question as well. If Washington DC were hit, every object in the the National Archives would be eviscerated in a moment. Terrified by this reality, they set out to save some of America’s most precious stuff. Today, we look back at the items our Cold War era planners sought to save and we ask the question: what objects would we preserve now?

    We first released this episode back in 2020, but with our big fourth of July – 250 years! – just around the corner, we thought it was a strange but profound reflection on what this whole America thing that we’re celebrating… actually is.

    Special thanks to Luke Manon, Ben Irving, Bill Pretzer, Jason Spier, and Garrett Graff for all his reporting that made this episode possible.

    The Gondolier

    26/06/2026 | 1h 13 mins.
    Back in 2017, reporters Kristen Clark and David Conrad came to us with a story that dug into the difficult and often dark places discrimination creates. We start in Venice, Italy, where they meet gondolier Alex Hai. On the winding canals in the hidden parts of Venice, we learn about the nearly 1000-year old tradition of the Venetian Gondolier, and how the global media created a 20-year battle between that tradition and a supposed feminist icon. 

    We circled back to Alex in 2026, to find out where the canal of life ended up leading after our initial reporting, and we’ve included some heartbreaking and heartwarming updates on Alex’s life at the end of this episode. 

    Special thanks to Alexis Ungerer, Summer, Alex Hai, Kevin Gotkin, Silvia Del Fabbro, Sandro Mariot, Aldo Rosso and Marta Vannucci, The Longest Shortest Time (Hillary Frank, Peter Clowney and Abigail Keel), Tim Howard, Nick Adams/GLAAD, Valentina Powers, Florence Ursino, Ann Marie Somma, Alex Overington, Jeremy Bloom and the people of Little Italy.

    This is Your Brain on Hormones

    19/06/2026 | 39 mins.
    After reading something that said her menstrual cycle changes her brain each month, Senior Correspondent Molly Webster goes on a reporting mission to see if that’s true, and, if so, how.

    This journey into sex hormones and the brain involves females and males, and exacting self-experimentation. It gets into PTSD, and ends with a new twist on self-care (hint: it’s biological). And, it starts to reveal a sneaky truth: that each one of us is at the mercy of a crashing sea of chemicals inside of us – those things we call hormones.

    Special thanks to Emily Jacobs, Laura Pritschet, Pavel Shapturenka, and Dr. Catherine Woolley.
