Asteroids are rich in precious metals and other valuable resources. But mining them presents considerable challenges. We discuss these, and consider how these spinning, rocky resources might be the key to a space-faring future. But an economist points out the consequences of bringing material back to Earth, and a scientist raises an ethical question; do we have an obligation to keep the asteroids intact for science?Guests:Jim Bell - Planetary scientist in the School of Earth and Space Exploration at Arizona State University.Martin Elvis - Astronomer and author of “Asteroids: How Love, Fear, and Greed Will Determine Our Future in Space.”Ian Lange - Economist and associate professor at the Colorado School of Mines and author of a paper on the feasibility of asteroid mining.Featuring music by Dewey Dellay and Jun MiyakeOriginally aired March 18, 2024You can get early access to ad-free versions of every episode by joining us on Patreon.

Firing federal workers and freezing grants has upended research institutions, prompting uncertainty about their futures. We look at the real-world impacts these policy changes may have for our mechanisms for collecting and sharing important data. An NIH grant recipient considers the future of her lab’s ability to do basic research, including studying complex diseases such as Alzheimer’s and heart disease. An interruption in reliable access to CDC data comes as highly contagious avian influenza continues to evolve and spread in the U.S. And what does the gutting of NOAA imply for collecting essential weather data, including those used to forecast hurricanes?

Two infectious diseases that we’ve been able to prevent for a half-century are re-emerging. One of the most contagious viruses in the world, measles, is spreading in the United States. Anti-vax sentiment has driven vaccination rates down leading to outbreaks in Texas and New Mexico. The U.S. has also seen an uptick in cases of tuberculosis which has reclaimed its position as the deadliest infection globally. The author John Green shares how his travels to Sierra Leone inspired his new book about TB. Through the story of a young patient, Henry, he highlights the health inequities that contribute to over a million and a half tuberculosis deaths annually despite the existence of a cure.Guests:Adam Ratner – Pediatric infectious disease doctor in New York City, and author of Booster Shots: The Urgent Lessons of Measles and the Uncertain Future of Children's HealthJohn Green – Author of The Fault in Our Stars, The Anthropocene Reviewed, and Everything is Tuberculosis: The History and Persistence of our Deadliest InfectionFeaturing 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.

By one estimate we spend a fifth of our lives watching movies or TV. In fact, we consume entertainment almost as habitually as we eat or sleep, activities that receive scientific scrutiny and study. So why not consider the effects that watching movies and TV have on our minds and bodies too? When we do, we find that they are not mere escapism. A data scientist reveals why we are what we watch, and how scientists and filmmakers work, often with competing agendas, to create sci-fi entertainment.Guest:Walt Hickey - journalist, data scientist, and author of “You Are What You Watch: HowMovies and TV Affect Everything”Featuring music by Dewey Dellay and Jun MiyakeOriginally aired January 8, 2024 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.

Is your windshield accumulating less bug splatter? Insects, the most numerous animals on Earth, are becoming scarcer, and that’s not good news. They’re essential, and not just for their service as pollinators. We ask what’s causing the decrease in insect populations, and howcan it be reversed. Also, the story of how California’s early citrus crops came under attack – a problem that was solved by turning Nature on itself. And how chimpanzee “doctors” use insects to treat wounds.We investigate the small and the many on “The Latest Buzz.”Guests:Martin Kernan – Historian and journalist. His article, “The Bug That Saved California,” appeared in the January-February 2022 issue of the SmithsonianAlessandra Mascaro – Evolutionary  Biologist, currently working at the Ozouga Chimpanzee Project, co-author of the Current Biology paper, “Application of insects to wounds of self andothers by chimpanzees in the wild”Lara Southern – Doctoral student at the University of Osnabruck, co-author of the Current Biology paper, “Application of insects to wounds of self and others by chimpanzees in the wild”Oliver Milman – Environment correspondent for The Guardian in the U.S. and author of “The Insect Crisis: The Fall of the Tiny Empires that Run the World”Featuring music by Dewey Dellay and Jun MiyakeOriginally aired March 28, 2022Big 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 the Chinese developer of DeepSeek released its model R1, a rift opened up in Silicon Valley. The company, a relatively unknown player, appeared to have created a better and cheaper model than its American competitors. Some big voices in the tech world called it a “Sputnik moment.” Others worried that the open-source model would allow malicious actors to harness the power of this AI technology. But did the arrival of DeepSeek significantly change how artificial intelligence will unfold? We explore that question and ask whether one particular sci-fi franchise got it right when portraying our anxiety about runaway AI.  Guests:Alex Kantrowitz – Tech journalist and founder of the podcast and newsletter Big TechnologyKristian Hammond – Professor of computer science at Northwestern University and Director of the Center for Advancing Safety of Machine IntelligenceDorian Lynskey – podcaster and author of “Everything Must Go: The Stories We Tell About the End of the World” 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.

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.

Animals experience the world differently. There are insects that can see ultraviolet light, while some snakes can hunt in the dark thanks to their ability to sense infrared. Such differences are not restricted to vision: Elephants can hear subsonic sounds, birds navigate by magnetism, and your dog lives in a world marked by odors. In this episode, we speak to science journalist Ed Yong about how other creatures sense the world. Could we ever understand what it’s like to have the hearing of a bat or the sight of a hawk? Guest:Ed Yong – Science writer for The Atlantic whose coverage of the COVID-19 pandemic earned him a Pulitzer Prize in explanatory journalism. He is the author of, “An Immense World: HowAnimal Senses Reveal the Hidden Realms Around Us.” Featuring music by Dewey Dellay and Jun MiyakeOriginally aired September 5, 2022Big 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.Thanks for your support!  Learn more about your ad choices.

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.
