Cicadapalooza
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 explore how cicadas have captivated our human ancestors for millennia.

The Birds and the Beans
"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 through Panama’s coffee farms as we learn all about the birds and the beans.
Guests:

Dude, Where’s my Carbon?
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 how carbon is measured, and why so much ends up in tropical forests.
Guests:
Joshua Tewksbury, director of the Smithsonian Tropical Research Institute in Panama
Helene Muller-Landau, senior scientist at the Smithsonian Tropical Research Institute researching tropical forests and ecosystems, leader of ForestGEO Global Carbon Program

Monkeyin' Around on the Devil's Island

Face Value
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 whose likeness gets engraved in our national story? And who makes these decisions? We’ll follow the money to find out.
Guests:
Jennifer Schneider, former program manager at Smithsonian American Women’s History Museum, current assistant registrar of outgoing and government loans at the Smithsonian American Art Museum
Tey Marianna Nunn, former director of the American Women’s History Initiative at the Smithsonian American Women’s History Museum, current associate director for content and interpretation at the Smithsonian’s National Museum of the American Latino
