A Tale To Warm The Cockles Of Your Heart 2020-04-07 13:43:00 You might have heard of Molly Malone, selling cockles from a wheelbarrow in Dublin, or of Mary, Mary, Quite Contrary, with her cockle shells and pretty maids all in a rowbut the chances are most Gastropod listeners have never actually tasted a cockle. And, apparently, you're missing out! For the Native American tribes in the Puget Sound, where cockles used to be abundant, they're a treasured treat: meatier, sweeter, and richer-tasting than other shellfish. But they're also disappearing, and no one knows whyor how to save them. This episode, we join the team of intrepid marine biologists and tribal leaders on a mission to restore the cockle, on a journey that involves cockle viagra, a cockle vampire, and some carefully choreographed simultaneous spawning. Listen in now for a story of shellfish science and cultural history that will warm the cockles of your heartand perhaps inspire the revival of other indigenous foods.
White vs. Wheat: The Food Fight of the Centuries 2020-03-24 14:36:08 White or whole wheat: while today the question is most frequently asked at the sandwich counter, the debate over the correct answer goes back literally thousands of years. In the past century, though, as white flour and thus white bread became more accessible, the debate became increasingly heated: "Science finds that white bread develops criminals," reported newspapers in the 1920s, while anti-white bread activists at the time claimed that eating too many slices would causing blindness and facial deformity. But whole-wheat bashers had their retorts ready: "Whiteness and purity go hand in hand," proclaimed health writer Dr. Woods Hutchinson. "The whitest possible of white bread" is "not only much more appetizing, but ... more nutritious and more wholesome than any black, brown or brindled staff of life."
White vs. wholewheat: this episode, we dive into the world's longest-running, highest-stakes food fight. Along the way: the invention of sliced bread, the science behind Wonder Bread's curious bounce, and a light dusting of eugenics. Listen in now as Aaron Bobrow-Strain, author of White Bread: A Social History of the Store-bought Loaf, unpacks the anxieties and values underlying the bread wars, while wheat breeder Steve Jones introduces us to the "approachable" loaf that he hopes will win the battle for once and for all.
Licorice: A Dark and Salty Stranger 2020-03-10 11:58:00 Licorice is a polarizing candy: there are those who pick out the black jelly beans, those who think Twizzlers are better than Red Vines, and those who won't travel without a supply of salty dark lozenges. The dark and chewy treat begins life as a plant root that is more than fifty times as sweet as sugar. This episode, we tell the story of how a traditional remedy become England's first branded candy, and we get to the bottom of a medical mystery (licorice poisoning!) in a tale that involves both Tutankhamun and Henry VIII.

Space One of the most consistent questions we get at the show is from parents who want to know which episodes are kid-friendly and which aren't. So today, we're releasing a separate feed, Radiolab for Kids. To kick it off, we're rerunning an all-time favorite episode: Space.
In the 60's, space exploration was an American obsession. This hour, we chart the path from romance to increasing cynicism.
We begin with Ann Druyan, widow of Carl Sagan, with a story about the Voyager expedition, true love, and a golden record that travels through space. And astrophysicist Neil de Grasse Tyson explains the Coepernican Principle, and just how insignificant we are.
