Social Media and the Subway 14.08.2024 21:28
There aren’t many portrait artists who get recognized on the street, but it happens to Devon Rodriguez all the time. After quietly honing his skill for a decade, Devon started posting videos of his live drawings of New York City subway commuters to social media. The videos took off, earning him some 50 million followers and placing portraiture in front of a huge new audience. In this episode of th...
Archiving the Underground 31.07.2024 38:06
Next up in our summer playlist, we bring you an episode of The Kitchen Sisters Present, a podcast featuring sound-rich stories ‘from the b-side of history.’ This one is a musical treat! The Kitchen Sisters delve into the story of the founding of the Hiphop Archive and Research Institute at Harvard by Dr. Marcyliena Morgan, Professor of African and African American Studies and Professor Henry Louis...
Rocket Man 17.07.2024 40:53
In the twentieth century, the jetpack became synonymous with the idea of a ‘futuristic society.’ Appearing in cartoons and magazines, it felt like a matter of time before people could ride a jetpack to work. But jetpacks never became a mainstream technology, leaving many to wonder…why? In this episode of 99 Percent Invisible, producer Chris Berube travels to the Udvar-Hazy Center of the Smithsonia...
A Giant Listening Project 03.07.2024 25:26
It’s been called ‘the most noble and absurd undertaking ever attempted by any state.’ During the height of the Great Depression, the U.S government hired out-of-work writers and laid-off reporters and sent them out to record the stories of all kinds of Americans. Called the Federal Writers’ Project, historians have called the program a giant “listening project.” While on our summer break, we’re sh...
The Lost Woolly Dog 19.06.2024 41:07
For thousands of years, fluffy white dogs could be found across the Pacific Northwest. Their exceptionally soft, crimpy hair was shorn like sheep’s wool, spun into yarn, and woven into blankets and robes by indigenous women who carefully tended them in communities across Coast Salish territory. But a hundred years ago, the woolly dog quietly vanished. Why? Today, the only known pelt of this extin...
Cosmic Journey II: Voyage into the Abyss 05.06.2024 32:10
Hitch a ride on the Chandra X-ray Observatory as it scours deep space for some of the most enigmatic and misunderstood objects in the universe: black holes. What are they good for? Absolutely something. This is the second episode of a two-part journey celebrating the 25th anniversary of the Chandra X-ray Observatory and the Smithsonian Astrophysical Observatory 's operation of the space telescope....
Cosmic Journey I: Chandra and the Black Hole 22.05.2024 34:37
Black holes could unlock the mysteries of creation and live at the heart of nearly every galaxy. But these invisible balls of extremely dense matter have never been fully understood, especially when they were only a theory. We travel through a cosmic wormhole back to the 1930s to learn how the first astrophysicist to successfully theorize a black hole, Subrahmanyan Chandrasekhar, was ridiculed and...
Cicadapalooza 08.05.2024 33:04
The cicadas are back for some fun in the sun, and this time, they’re louder than ever! For the first time since 1803, Broods XIII and XIX will be emerging at the same time, covering the American South and Midwest with trillions of cicadas. As Smithsonian entomologist Floyd Shockley readies his nets for the biggest bug invasion in centuries, we look back at the emergence of Brood X in 2021, and exp...
The Birds and the Beans 24.04.2024 37:21
"God in a cup." "Perfection." "The world's best coffee." Panamanian geisha coffee has been called many things, but never Smithsonian Bird Friendly certified. That might soon change, however, as researchers from Smithsonian National Zoo and Conservation Biology Institute’s Migratory Bird Center find new ways to grow coffee in harmony with migratory songbirds. Join us for this fully caffeinated romp...
Dude, Where’s my Carbon? 10.04.2024 32:36
If you’ve bought a plane ticket recently, you’ve probably had the option to pay a few extra dollars to offset your carbon emissions. That money might go toward planting some trees… but how many trees? Researchers at the Smithsonian Tropical Research Institute are trying to answer this very question by hand-measuring trees, weighing wood, and climbing to the top of the canopy. We tag along to see h...
Monkeyin' Around on the Devil's Island 27.03.2024 28:24
It started as a rumor in the cafeteria of the Smithsonian Tropical Research Institute in Panama: monkeys on an island in the Pacific were doing something no one had ever seen them do before. But when researchers went searching for these elusive capuchin monkeys, they discovered more questions than answers. Guests: Claudio Monteza , Smithsonian Tropical Research Institute fellow and researcher at t...
Face Value 13.03.2024 31:54
Money is power. But who's on our money - or isn’t - can be just as powerful. While Lady Liberty has graced American coins and dollars for most of our history, it wasn’t until the 1970s that a real woman appeared on a circulating American coin. But that's about to change. Congress recently authorized the creation of twenty new quarters featuring American women from history. But how do we decide who...
Jeepers Leapers! 28.02.2024 13:30
Did you know a person born on February 29 is called a "leapling"? This special episode is hopping with Leap Day trivia! Like, why do we need an extra day every four years anyway? And will I get paid for working an extra day in February? It's the lowdown on Leap Day in an episode that's as off-kilter as the earth's axis. Guest: Bob Craddock, Geologist at the Smithsonian's National Air and Space Mus...
Til Death Do Us Part? 14.02.2024 29:20
They say love is eternal. What about heartbreak? This Valentine’s Day, we bring you some of Japanese theater’s most popular tales of scorned lovers seeking vengeance from beyond the grave — with a burning passion. Guests: Frank Feltens , Curator of Japanese Art at the Smithsonian’s National Museum of Asian Art Kit Brooks , Japan Foundation Assistant Curator of Japanese Art at the Smithsonian’s Na...
To Sidedoor, With Love 31.01.2024 36:22
From brontosauruses with bronchitis to birds on a wire to flying space rocks and a botched heist at 20 thousand feet. In this episode, Lizzie and Sidedoor producer James run all around the Smithsonian to answer listeners' questions from the Sidedoor mailbag. Guests: Lynn Heidelbaugh , curator at the Smithsonian’s National Postal Museum Sara Hallager , curator of birds at the Smithsonian’s National...
Tails of Bravery 17.01.2024 46:31
As long as there have been wars, animals have joined their human companions on the battlefield. But a few have served so bravely they’ve been memorialized at the Smithsonian. In honor of these furry and feathered war heroes, we bring you the tales of dogs, cats and birds who went above and beyond the call of duty. Guests: Jennifer Jones , curator of military history at the Smithsonian's Nationa...
The Milkmaid Spy 03.01.2024 28:55
Virginia Hall dreamed of being America’s first female ambassador. Instead, she became a spy. Joining the ranks of the U.S.’s first civilian spy network, she operated alone in occupied France, where she built French Resistance networks, delivered critical intelligence, and sold cheese to the enemy. All on one leg. Guests: Sonia Purnell , author of “A Woman of No Importance: the Untold Story of the...
Auld Lang What? 20.12.2023 21:18
It’s a song we often hear at the start of the new year. But what does “auld lang syne” even mean? And how did it come to be associated with New Year's Eve? With a little musical sleuthing, we find Charlie Chaplin might have something to do with it… Guests: James Deutsch , curator of folklife and popular culture at the Smithsonian Center for Folklife and Cultural Heritage
Welcome Back, Otter 06.12.2023 26:07
North American River Otters are popping up in places they haven't been seen in decades and nobody really knows why.

Guests: Katrina Lohan, head of the Coastal Disease Ecology Laboratory at the Smithsonian Environmental Research Center Alejandra Morales Picard , psychologist at Montgomery College Rebecca Stu...
Wrinkled Radicals 22.11.2023 31:20
When Maggie Kuhn was forced to retire from the job she loved at age 65, her colleagues gave her a sewing machine as a parting gift. Outraged, she shut the sewing machine in a closet and, instead, stitched together the first-ever movement against ageism in the U.S. The Gray Panthers would galvanize gray haired citizenry and youth alike to challenge the way Americans think about aging. Guests : Kat...
Farewell Giant Pandas 08.11.2023 29:23
All three Giant Pandas are leaving the Smithsonian's National Zoo for China by the end of the year. What's up with that?! We sat down with the director of the Zoo, Brandie Smith, to find out why the pandas are leaving, and whether China plans to send more. This might truly be the end of a beara ... we mean era! Guests: Brandie Smith, John and Adrienne Mars Director of the Smithsonian’s National Zo...
Resurrected: Spooked at the Smithsonian 25.10.2023 37:54
The Smithsonian Institution was founded on principles of reason and scientific inquiry. So why is the Smithsonian home to countless tales of unexplained phenomena and—dare we say—ghost sightings? Inspired by an apparition at the National Museum of American History, we creak across museum attic floorboards, sneak into an old house in the woods, and even travel back in time to bring you a collection...
CSI: Southern Pacific 11.10.2023 38:56
Looks like these criminals used correct postage, 'cause justice is about to be delivered. Okay, there are no snappy one-liners in this crime scene investigation, but there are explosions, collisions, manhunts and even a cow who was in the wrong place at the wrong time. On the centennial of "The Last Great Train Robbery," we re-examine the evidence to find out how U.S. Postal Inspectors tracked dow...
Cellphones Rock 27.09.2023 28:22
Cellphones put the power of the world at our fingertips. With the touch of a finger, you can instantly connect with your doctor, have food delivered to your office or simply obliterate your niece at Words with Friends. And it's all made possible by rocks formed millions of years ago, deep underground. Join us as we bust open our devices to figure out how these stones power our phones. Guests: Josh...
The 'Gentle Anarchy' of the Muppets 13.09.2023 33:32
Icky Gunk. Moldy Hay. Kermit. You might recognize one of these names. Before Kermit joined Miss Piggy and Big Bird, he was kicking it with Sam and Friends — a local tv show in Washington, D.C. that launched Jim Henson's career. We journey back to 1955 to figure out how this eccentric cast of puppets built the foundation for everything Jim Henson would do afterwards, from Sesame Street, to The Mupp...
