The surprising connections in science and technology that give you the Big Picture. Astronomer Seth Shostak and science journalist Molly Bentley are joined each week by leading researchers, techies, and journalists to provide a smart and humorous take on science. Our regular "Skeptic Check" episodes cast a critical eye on pseudoscience.

How frequently do you think about fasteners like screws and bolts? Probably not very often. But some of them a storied history, dating back to Egypt in the 3rd century BC. They aren’t just ancient history. They help hold up our bridges and homes today. Join us as we dissect a handful of engineering inventions that keep our world spinning and intact.
Guests:
Roma Agrawal - structural engineer and author of "Nuts and Bolts: Seven Small Inventions That Changed the World (in a Big Way)"
Ron Gordon - watchmaker, New York City
Featuring music by Dewey Dellay and Jun Miyake

Big Picture Science

Nuts and Bolts

It was a radical idea a century ago, when Einstein said space and time can be bent, and gravity was really geometry. We hear how his theories inspire young minds even today.
At small scales, different rules apply: quantum mechanics and the Standard Model for particles. New experiments suggest that muons – cousins of the electron – may be telling us that the Standard Model is wrong. Also, where the physics of both the large and small apply, and why black holes have no hair.
Guests:
Hakeem Oluseyi – Astrophysicist, affiliated professor at George Mason University, and author of “A Quantum Life: My Unlikely Journey from the Street to the Stars”
Janna Levin – Professor of physics and astronomy, Barnard College at Columbia University
Mark Lancaster – Professor of particle physics, University of Manchester

Phreaky Physics*

Above the Arctic Circle, much of the land is underlaid by permafrost. But climate change is causing it to thaw. This is not good news for the planet. 
As the carbon rich ground warms, microbes start to feast… releasing greenhouse gases that will warm the Earth even more.
Another possible downside was envisioned by a science-fiction author. Could ancient pathogens–released from the permafrost’s icy grip–cause new pandemics? We investigate what happens when the far north defrosts.
Guests:
Jacquelyn Gill – Associate professor of paleoecology at the University of Maine.
Jim Shepard – Novelist and short story writer, and teacher of English at Williams College, and author of “Phase Six.”
Scott Saleska – Global change ecologist, professor of Ecology and Evolutionary Biology at the University of Arizona, and co-founder of IsoGenie.

De-Permafrosting*

Birds have it going on. Many of these winged dinosaurs delight us with their song and brilliant plumage. Migratory birds travel thousands of miles in a display of endurance that would make an Olympic athlete gasp.
We inquire about these daunting migrations and how birds can fly for days without rest. And what can we do to save disappearing species? Will digital tracking technology help? Plus, how 19th century bird-lovers, appalled by feathered hats, started the modern conservation movement.
Guests:
Scott Weidensaul – Ornithologist and naturalist and author of “A World on the Wing: the Global Odyssey of Migratory Birds.”
Kassandra Ford – Doctoral candidate in evolutionary biology at the University of Louisiana at Lafayette.
Michelle Nijhuis – Science journalist and author of “Beloved Beasts: Fighting for Life in an Age of Extinction.”
