Catalytic converters are disappearing. If you’ve had yours stolen, you know that precious and rare earth metals are valuable. But these metals are in great demand for things other than converters, such as batteries for electric cars, wind farms and solar panels.We need rare earth metals to combat climate change, but where to get them? Could we find substitutes?One activity that could be in our future: Deep sea mining. But it’s controversial. Can one company’s plan to mitigate environmental harm help?Guests:Paul Dauenhauer - Professor of chemical engineering and material science at the University of Minnesota and a 2020 MacArthur FellowChris Leighton - Distinguished University Teaching Professor, Editor, Physical Review Materials, Dept. of Chemical Engineering and Materials Science, University of MinnesotaRenee Grogan - Co-founder and Chief Sustainability Officer, Impossible Mining companyOriginally aired January 17, 2022Featuring music by Dewey Dellay. Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.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.

Climate change isn’t waiting for us to act. We’ve missed several deadlines to mitigate the dangers of this existential threat, which suggests we prefer to avert our gaze rather than deal with the problem. It’s similar to the way society reacts to an incoming comet in the movie “Don’t Look Up!” As a major Antarctic ice sheet shows signs of collapse, it’s no wonder we feel some “climate anxiety.” Can we leverage this emotion to spur action? That, and where hope lies, in this episode.Guests:Joellen Russell – Oceanographer and climate scientist at the University of ArizonaKatie Mack – Professor of Theoretical Physics at North Carolina State University, and author of “The End of Everything (Astrophysically Speaking)”Jessica Tierney – Professor of Paleoclimatology at the University of ArizonaSusan Clayton – Professor of Psychology and Environmental Studies, College of WoosterOriginally aired February 21, 2022Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.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: How Animal Senses Reveal the Hidden Realms Around Us.” Originally aired September 5, 2022Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.com to inquire about advertising on Big Picture Science.  Learn more about your ad choices.

5G, the latest mobile network standard, is coming. As new cell towers sprout around the world, do we know enough to confidently claim that this new technology is safe? After all, older networking standards relied on microwaves, radiation which has wavelengths of inches to a foot or so. 5G operates at much higher frequencies, with millimeter wavelengths.Some are worried that being subjected to millimeter radiation could cause cancers. But what does science say? 5G: the promise and the perils.Guests:Jon Samet – Pulmonary physician, epidemiologist, and dean of the Colorado School of Public Health.Claire Parkinson – Scientist, NASA’s Goddard Space Flight CenterBob Berman – Astronomer, regular contributor to Astronomy Magazine, and author of “Zapped: From Infrared to X-Rays, the Curious History of Invisible Light”David Ropeik – Retired Harvard instructor and author of several books about the psychology of risk perception.Originally aired February 28, 2022Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.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.

A century ago, British archaeologist Howard Carter opened the only surviving intact tomb from ancient Egypt. Inside was the mummy of the boy king Tutankhamun, together with “wonderful things” including a solid gold mask.Treasure from King Tut’s crypt has been viewed both in person and virtually by many people since. We ask what about Egyptian civilization so captivates us, thousands of years later. Also, how new technology from modern physics allows researchers to “X-Ray” the pyramids to find hidden chambers.Guests:Emma Bentley – Postgraduate student in Archeology and Ancient Worlds at the University of Edinburgh in the U.K. Sarah Parcak – Archaeologist and Egyptologist, University of Alabama, and author of “Archaeology From Space: How the Future Shapes Our Past.”Richard Kouzes – Physicist at the Department of Energy’s Pacific Northwest National Laboratory.Salima Ikram – Professor of Egyptology at The American University in Cairo and head of the Animal Mummy Project at the Egyptian Museum in Cairo.Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.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.

Modern technology is great, but could we be losing control? As our world becomes more crowded and demands for resources are greater, some people worry about humanity’s uncertain prospects. An eminent cosmologist considers globe-altering developments such as climate change and artificial intelligence. Will we be able to stave off serious threats to our future?There’s also another possible source of danger: our trendy digital aids. We seem all-too-willing to let algorithms classify and define our wants, our needs, and our behavior. Instead of using technology, are we being used by it – to inadvertently become social media’s product? And while we may be skittish about the increased data our technology collects, one sci-fi writer imagines a future in which information is a pervasive and freely available commodity. Guests:Martin Rees – Cosmologist, astrophysicist, and Great Britain’s Astronomer Royal. Author of On the Future: Prospects for Humanity.Douglas Rushkoff – Media theorist and professor of media theory and digital economics, City University of New York. Author of Team Human.Malka Older – Author and humanitarian worker, author of The Centenal Cycle.Originally aired February 11, 2019Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.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.

A new theory about life’s origins updates Darwin’s warm little pond. Scientists say they’ve created the building blocks of biology in steaming hot springs. Meanwhile, we visit a NASA lab where scientists simulate deep-sea vent chemistry to produce the type of environment that might spawn life. Which site is best suited for producing biology from chemistry?Find out how the conditions of the early Earth were different from today, how meteors seeded Earth with organics, and a provocative idea that life arose as an inevitable consequence of matter shape-shifting to dissipate heat. Could physics be the driving force behind life’s emergence? Guests:Caleb Scharf – Director of Astrobiology at Columbia University, New YorkLaurie Barge – Research scientist in astrobiology at NASA’s Jet Propulsion LaboratoryBruce Damer – Research scientist in biomolecular engineering, University of California, Jeremy England – Physicist, Massachusetts Institute of TechnologyOriginally aired May 13, 2019Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.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.

A radical plan could solve a historic global health inequity. Countries in the global south who waited for more than a year for ample supplies of Covid vaccines have banded together to make mRNA vaccines locally. If successful, they could end a dangerous dependency on wealthy nations and help stop pandemics before they start.In a special episode, supported by the Pulitzer Center, journalist Amy Maxmen shares her reporting from southern Africa about the inspiring project led by the WHO that’s made fast progress. But it could fail, and a global imbalance will remain, if Big Pharma has its way. Find out what’s at stake.Guests:Amy Maxmen - Award-winning science journalist, Edward R.

Declining biodiversity is a problem as fraught as climate change.Loss of habitat, monoculture crops, and the damming of waterways all lead to massive species extinction. They tear at life’s delicate web, and threaten a balance established by four billion years of evolution.Can we reassess our relationship to Nature? We consider logging efforts that make elephants part of the work force, and how to leverage the cooperative behavior of trees.Becoming Nature’s ally, rather than its enemy.Guests: Suzanne Simard – Professor of Forest Ecology at the University of British Columbia and author of “Finding the Mother Tree: Discovering the Wisdom of the Forest.” Carl Safina – Professor of Nature and Humanity at Stony Brook University and founder of the Safina Center, and author of “Becoming Wild: How Animal Cultures Raise Families, Create Beauty, and Achieve Peace.” Jacob Shell – Professor of Geography and Urban Studies at Temple University, and author of “Giants of the Monsson Forest: Living and Working with Elephants.” Originally aired November 8, 2021Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.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.
