• Black Sheep Metal

  Lead is a study in contradictions. It’s dense enough to stop an X-ray, but soft enough to scratch with your fingernail. It’s heavier than steel and iron, but also more flexible. And, despite evidence of its toxicity, humans have been using it for all sorts of things for thousands of years. In this edition of our series “The Element of Surprise,” we hone in on this notorious heavy metal. What chemical properties make lead so harmful? How did something so dangerous become so ubiquitous? And if medical authorities acknowledge no amount of lead exposure is safe – especially for children – why do so many of us have lead in our water and our homes?Featuring Justin Richardson, Bruce Lanphear, and Chakena Perry.This episode was produced by Kate Dario.

It’s wild and worth a listen. A comprehensive history of leaded gasoline and an in-depth investigation of how the lead industry lobbied cities to use lead pipes. Gerald Markowitz and David Rosner have published numerous books covering the American lead industry and lead’s lasting public health impacts. The EPA has robust resources about how to deal with lead exposure and how to minimize your risk.

• The Cold War Ice Core of Greenland

  In the late 1950s, engineer Herb Ueda Sr. traveled to a remote Arctic military base. His mission? To drill through nearly a mile of ice, and extract the world’s first complete ice core.To finish the job, he and his team would endure sub-zero weather, toxic chemicals, and life inside a military base… which was slowly being crushed by the glacier from which it was carved. In this episode (first released in 2023) Daniel Ackerman takes us inside Camp Century, and explains how a foundational moment in climate science was inextricably linked with the United State's military interest in Greenland.Featuring Curt La Bombard, Julie Brigham-Grette, Herb Ueda Jr., Don Garfield, and Aleqa Hammond.Produced by Daniel Ackerman.

• Dark Magic Rabbit

  A magician spins a black top hat to show their audience it’s empty. Then, with the wave of a wand and a few magic words, PRESTO: a snow white rabbit pokes its ears over the brim. Compared to sawing a person in half, pulling a rabbit out of a hat is a joyful bit of magic that entertainers have been doing for more than 200 years. But after the applause dies down, one is left wondering: where did the rabbit come from? And where did it go? Today, in honor of the Easter Bunny (who doesn’t actually appear in this episode), we’re pulling a handful of rabbit stories out of our proverbial hat. But be warned: these are dark tales of disappearing pets, occult eugenicists, and animal sacrifice. The secrets behind some magic tricks are more shocking than others. Featuring Nicole Cardoza, Gwyne Henke, Suzanne Loui, Sally Master, Ana DiMaria, Tanya Singer, and Meg Crane. Produced by Nate Hegyi, Marina Henke, Kate Dario, and Justine Paradis.

• The Bee’s Sneeze: Why allergies are getting worse

  Allergies have been documented in historical records dating as far back as 2,400 years ago, when Hippocrates wrote about “hostile humors” in some people who suffered badly after eating cheese. But why do we experience them to begin with? What even is an allergy? Are allergies on the rise? And why are some mere nuisances, while others are deadly?This episode is a roundup of allergy stories—from the mundane to the frightful—and a round up of allergy questions we’re asking Dr. Theresa MacPhail, author of Allergic: Our Irritated Bodies in a Changing World, to answer for us.Featuring Beni Osei Duker, Theresa MacPhail, Dwayne Smith, and Lily Ko.Produced by Felix Poon.

• Venom and the cure

  Venom is full of dualities. According to the UN’s World Health Organization, snakebite envenoming causes somewhere between 81,000 and 138,000 deaths per year, and even that is likely an undercount. Yet research into venom has yielded treatments for diabetes, cancer, erectile dysfunction, and even the celebrity favorite diabetes slash diet drug, Ozempic. In this episode, we explore the world of venom, where fear and fascination go hand-in-hand, and the potential for healing comes with deadly stakes. This is part II of our “Things That Can Kill You” miniseries, which also explores poison and allergies.Featuring Sakthi Vaiyapuri.
