Everyone knows that a big rock wiped out the dinosaurs. But the danger from an asteroid hitting Earth is not limited to ancient history. To deal with this threat, scientists recently ran an experiment to deflect a potential “city killer.” We’ll hear the results of that experiment, and about a visit to another asteroid. In the dusty material NASA brought back from the asteroid Bennu, scientists found the chemical building blocks of life, including many of the amino acids that are found in our cells. Could an asteroid have brought the ingredients for life to ancient Earth? In this episode, we look at our paradoxical relationship with the space rocks that taketh way – and may help giveth - life.Guests:Scott Sandford - Astrophysicist and Research Scientist at NASA’s Ames Research CenterRobin George Andrews - Science journalist, volcanologist, and author of "How to Kill an Asteroid: The Real Science of Planetary Defense"Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

In this engaging discussion, Ed Yong, a Pulitzer Prize-winning science writer for The Atlantic, explores the fascinating sensory worlds of animals. He illustrates how creatures like elephants and mantis shrimp perceive their environments through infrared and ultraviolet light, senses beyond human comprehension. The conversation delves into the ethical implications of understanding these unique experiences, the diverse definitions of intelligence, and the importance of empathy in our interactions with wildlife.

We have an update to our recent episode, Skeptic Check: Drone Panic. If you remember, our guest astronomer Andrew Franknoi recalled the story of Jimmy Carter having seen something mysterious in the sky when he was governor of Georgia in 1969. Astronomers at the time suggested it was likely Venus, as has been the case with other sightings, and for decades that was a widely accepted understanding of what he saw. But there is more to the story, as was brought to our attention by multiple BPS listeners. So, we invited Andrew back to discuss the revised account, and its more satisfying scientific resolution.Guest:Andrew Fraknoi - Professor of Astronomy at the Fromm Institute of the University of SanFrancisco Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

When several mysterious objects were spotted flying over New Jersey, their unknown identity led to frightening rumors, and triggered frustration and alarm among some residents of the Garden State. What were these objects, and if they were drones, as some appeared to be, were they friendly or foe? Many of the objects have now been identified. We talk about what happened when calmer heads prevailed and consider what the Great Drone Panic might havein common with other episodes involving objects cruising the skies. Also, why one expert thinks the event gave birth to a new UFO subculture. Guests:Andrew Fraknoi - Professor of Astronomy at the Fromm Institute of the University of San Francisco Mick West - Investigator of conspiracy theories and UFO sightingsGreg Eghigian - Professor of history and bioethics at Penn State and author of “After the Flying Saucers Came: A Global History of the UFO Phenomenon”Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

After helping to sequence the human genome more than twenty years ago, biochemist Craig Venter seemed to recede from the public eye. But he hadn’t retired. He had gone to sea and taken his revolutionary sequencing tools with him. We chatted with him about his multi-year voyage aboard the research vessel Sorcerer II, its parallels to Darwin’s voyage, and the surprising discoveries his team made about the sheer number and diversity of marine microbes and their roles in ocean ecosystems.Guests:Craig Venter - Genomicist, biochemist, founder of the J. Craig Venter Institute, and co-author of “The Voyage of Sorcerer II: The Expedition that Unlocked the Secrets of the Ocean’s Microbiome.”Jeff Hoffman - Lab manager at the J.

Our information age is increasingly the disinformation age. The spread of lies and conspiracy theories has created competing experiences of reality. Facts are often useless for changing minds or even making compelling arguments. In this episode, author Naomi Klein and science philosopher Lee McIntyre discuss why the goal – not simply the byproduct - of spreading disinformation is to polarize society. They also offer ideas about how we might find our way back to a shared objective truth.  Guests:Naomi Klein - Associate professor of Geography at the University of British Columbia and a co-director at the Center for Climate Justice. Author of Doppelganger: A Trip Into the Mirror WorldLee McIntyre - Philosopher of science and a research fellow at the Center for Philosophy and the History of Science at Boston University, and author of Post-Truth and On Disinformation.Featuring music by Dewey Dellay and Jun MiyakeOriginally aired December 11, 2023 Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

“To live is to count and to count is to calculate.” But before we plugged in the computer to express this ethos, we pulled out the pocket calculator. It became a monarch of mathematics that sparked a computing revolution. But it’s not the only deceptively modest innovation that changed how we work and live. Find out how sewing a scrap of fabric into clothing helped define private life and how adding lines to paper helped build an Empire. Plus, does every invention entail irrevocable cultural loss?Guests:Keith Houston – author of “Empire of the Sum: The Rise and Reign of the Pocket Calculator.”Hannah Carlson – teaches dress history and material culture at the Rhode Island School of Design, author of “Pockets: An Intimate History of How We Keep Things Close.”Dominic Riley – bookbinder in the U.K.Featuring music by Dewey Dellay and Jun Miyake*Originally aired October 30, 2023Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.
