Food with a side of science and history. Every other week, co-hosts Cynthia Graber and Nicola Twilley serve up a brand new episode exploring the hidden history and surprising science behind a different food- or farming-related topic, from aquaculture to ancient feasts, from cutlery to chile peppers, and from microbes to Malbec. We interview experts, visit labs, fields, and archaeological digs, and generally have lots of fun while discovering new ways to think about and understand the world t ...

Today, a half century after Neil Armstrong took one small step onto the surface of the Moon, there are still just ten humans living in space—the crew of the International Space Station. But, after decades of talk, both government agencies and entrepreneurs are now drawing up more concrete plans to return to the Moon, and even travel onward to Mars.…

To painters and poets in late-1800s France, absinthe was "the green muse" or the "green fairy," an almost magical potion that promised vivid dreams, wild ideas, and artistic inspiration with every sip. By the 1910s, this once incredibly popular herbal liquor was banned—not only in France, but in countries around the world. Condemned as the cause of…

Every day, at the end of service, restaurants throw away tons of entirely edible food: heaps of pastries and whole loaves of bread, vegetables chopped but not cooked, noodle dough, fish off-cuts, and more. An estimated 20 billion meals's worth of still edible food overall is tossed every year here in the US, and more than 85 percent of it ends up i…

It’s already begun: that time of the year now known across the land as Decorative Gourd Season. Squash are everywhere—carved into jack o’lanterns on front porches, adorning our sideboards and porches with strange shapes and autumn colors, and of course, baked into pies for fall celebrations. But get ready to rethink squash, because despite their sl…

The produce section of most American supermarkets in the 1950s was minimal to a fault, with only a few dozen fruits and vegetables to choose from: perhaps one kind of apple, one kind of lettuce, a yellow onion, a pile of bananas. Today, grocery stores routinely offer hundreds of different fruits and vegetables, many of which would be unrecognizable…

School’s back in session, and kids are boarding the bus with lunchboxes in tow. Many of them contain sandwiches stuffed with turkey and ham slices, bologna, even salami—but where did these staples of the lunch break, not to mention the charcuterie platter, come from?

When you buy a bottle of rum in the United States, by law nearly all the federal taxes on that rum must be sent to Puerto Rico and the U.S. Virgin Islands. It's an unusual system that Congress designed decades ago to help fund these two U.S. territories. In 2021 alone, these rum tax payments added up to more than $700 million. Puerto Rico and the V…

Guest episode: In this episode we introduce you to a part of our bodies that was invisible to Western scientists until about five years ago; it’s called "the interstitium," a vast network of fluid channels inside the tissues around our organs that scientists have just begun to see, name, and understand. Along the way we look at how new technologies…
