The Nazi Cult of Mobility


The Nazi fascination with race is often linked with geography: the idea of an ancestral Aryan Homeland. But Nazis were not just obsessed with German soil, they were also fixated on ideas of movement and travel.

Andrew Denning talks about the Nazi cult of mobility, a set of ideas and practices that were crucial to its racist ideology. Denning is an Assistant Professor of Modern European History at the University of Kansas in Lawrence. He is the author of the essay “’Life is Movement, Movement is life!’ Mobility Politics and the Circulatory State in Nazi Germany,” published in the December 2018 issue of American Historical Review.

Replay: The Rise of Women in Climbing

For decades, the sport of climbing seemed to be “a guy thing” until a group of elite women climbers in the 1990s changed the landscape of the sport forever.

Free-lance journalist and climber Noël Phillips discusses the growing popularity of climbing for women at all levels. Her articles, “No Man’s Land: The Rise of Women in Climbing” and “Safe Outside: The Facts About Sexual Harassment and Assault in the Climbing Community” were published in Climbing Magazine.

The Last Wild Men of Borneo


Journalist Carl Hoffman talks about Bruno Manser and Michael Palmieri, two men who arrived in Borneo with very different dreams and aspirations.

Replay: The Amazing Phytotron


Climatron, Missouri Botanical Garden

“Phytotron” is such a great name for something that is, when you look at it, a high-tech greenhouse. But don’t sell it short! The phytotron was not only at the center of post-war plant science, but also connected to the Cold War, commercial agriculture, and long-duration space flight. 


Today I speak with David Munns, professor of history at John Jay College, about his new book, Engineering the Environment: Phytotrons and the Quest for Climate Control in the Cold War, but we also talk about Matt Damon, shitting in space, and growing pot in your dorm room.

Should We Colonize Mars?

Lucianne Walkowicz talks about the ethics of Mars exploration and new developments in the search for extraterrestrial life. Walkowicz is an astronomer and TED Senior Fellow at the Adler Planetarium in Chicago. This year she served as the Baruch S. Blumberg NASA/Library of Congress Chair in Astrobiology.

Replay: Chasing Exoplanets


One of the things you hear about space exploration is that if humans aren’t involved — that is, being hurled into orbit– no one’s going to pay much attention. Robots are one thing, astronauts are another. There may be some truth to this. But I think exoplanets — planets that orbit stars outside our own solar system– are soon going to prove this maxim wrong. No one is traveling to extra-solar planets any time soon, (especially Kepler-10b, a planet so close to its sun that its surface is a glurping ocean of molten lava) but they are the coolest thing coming out space science these days – an ever expanding menagerie of the spherically weird and wonderful. Scientists have identified almost 4000 exoplanets so far and — with powerful new telescopes about to come on line — they’re just getting started. 

Today I speak with exoplanet scientist Hannah Wakeford, Giaconni Fellow at the Space Telescope Science Institute. Wakeford has also served as a NASA Postdoctoral Research Fellow at NASA’s Goddard Space Flight Center and as a Research Fellow at the University of Exeter. She is also a host of the podcast, Exocast, along with co-hosts (and exoplanet scientists) Hugh Osborn and Andrew Rushby.

Searching for the Origins of Humankind

taylor, zones of migration, 1919

“Zones of Migration Showing the Evolution of the Races” Griffith Taylor, 1919

Historian Emily Kern talks about the search for human origins in the 19th and 20th centuries, specifically why anthropologists came to see Africa – rather than Asia – as the cradle of the human species. Kern is a Postdoctoral Research Associate in New Earth Histories at the University of New South Wales in Sydney, Australia where she specializes in the history of modern science. She is currently completing her book Out of Asia: a History of the Global Search for the Origins of Humankind.
