Tech in Check
Worried that AI will replace you? It may not seem like the Hollywood writers’ strike has anything in common with the Luddite rebellion in England in 1811, but they are surprisingly similar. Today we use the term “Luddite” dismissively to describe a technophobe, but the original Luddites – cloth workers – organized and fought Industrial Revolution automation and the factory bosses who were replacing humans with cotton spinning machines and steam powered looms. Find out what our age of AI can learn from textile workers of 200 years ago about keeping humansin the loop.Guest:Brian Merchant - Los Angeles Times tech columnist and author of “Blood in the Machine: TheOrigins of the Rebellion Against Big Tech” Featuring music by Dewey Dellay and Jun MiyakeOriginally aired January 14, 2024Big Picture Science is part of the Airwave Media podcast network.

Skeptic Check: Cryptids
Bigfoot could get official status if proposed legislation passes making it the state cryptid of California. If nothing else, the effort shows that fascination with cryptids has an outsized footprint on our culture. We look at why mythical creatures continue to capture imaginations - as well as passions - of die-hard believers, despite no evidence for their existence. An author uncovers the origin of a beloved hoax in the American West and its unexpected ties to a real animal and historical medical breakthrough. But are we looking for creature delights in all the wrong places? A tally of Earth’s species reveals that far more remain unidentified than are currently known. Newly discovered critters such as the Yeti crab and an organism dubbed theFlying Spaghetti Monster are so strange, it challenges us to separate fauna fact from folktale.Guests:Chris Rogers – Assemblymember, California’s 2nd Assembly DistrictBenjamin Radford – Deputy Editor of Skeptical Inquirer Science Magazine, author, and co-hostof Squaring the Strange podcastMichael Branch – Writer, humorist, and author of On the Trail of the Jackalope: How a Legend Captured the World’s Imagination and Helped Us Cure CancerBoris Worm – Marine ecologist, Professor of Biology at Dalhousie University in Halifax, Nova ScotiaFeaturing music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network.

Vroom!
Self-driving cars, once a thing of science fiction, have become a reality in a handful of cities across the country. As our vehicles gain autonomy, they may provoke a profound shift not unlike the introduction of the first car in the late1800s and raise the question of whether the human driver will soon be obsolete. For a glimpse into the future of self-driving cars, we take a spin through the history of the automobile, from the Model T to the driverless taxi-cab. Along the way, we explore the rise of American manufacturing and the unmistakable but unexpected way in which we have bonded to our four-wheeled companions.Guests:Witold Rybczynski – Professor emeritus of architecture and design at the University of Pennsylvania and author of the book, The Driving Machine: A Design History of the CarTimothy B Lee – Technology journalist and writer of the newsletter, Understanding AIFeaturing music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network.

Skeptic Check: Asteroid Mining
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.

Disappearing Data
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? Guests:Kimberly Cooper – Developmental biologist at the University of California, San DiegoAmy Maxmen – Public health reporter at KFF Health NewsAlan Sealls – Retired broadcast meteorologist, adjust professor at the University of South Alabama and president-elect of the American Meteorological SocietyBernadette Woods Placky – Chief meteorologist and Climate Matters director at the nonprofit organization, Climate Central Featuringmusic by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network.

Preventable
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.

Your Mind on Movies
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.

The Latest Buzz
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.

Skeptic Check: Into the DeepSeek
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.
