The idea that the universe is made of tiny vibrating strings was once the science theory du jour. String theory promised to unite the disparate theories describing particles and gravity, and many people, not just scientists, were optimistic that a theory of everything might be within our grasp. But here we are, many years later, and string theory doesn’t seem to have delivered on its initial promise. What happened? We consider the science around string theory in this episode of Skeptic Check.

Lithium Valley 54:00

לפני 4 ימים54:00

54:00

The discovery of a massive amount of lithium under the Salton Sea could make the U.S. lithium independent. The metal is key for batteries in electric vehicles and solar panels. But the area is also a delicate ecosystem. We go to southern California to hear what hangs in the balance of the ballooning lithium industry, and also how we extract other crucial substances – such as sand, copper and iron– and turn them into semiconductors, circuitry and other products upon which the modern world depends. Guests : Ed Conway – economics and data editor of Sky News and columnist for the Times in London. He’s the author of “ Material World, The Six Raw Materials that Shape Modern Civilization “. Frank Ruiz – Audubon California Salton Sea Program Director. Michael McKibben – Geologist, University of California, Riverside.

Hurricane Comms 55:55

לפני 18 ימים55:55

55:55

A big challenge during a hurricane or other disaster is keeping lines of communication open when the power goes out. In this episode, the second in our series tied to the 20th anniversary of hurricane Katrina, we report from the National Hurricane Conference in New Orleans about a technology used in 2005, and still employed today, to provide vital information during a crisis. In our age of growing reliance on cellphones and funding cuts to federal agencies tasked with disaster communications, could ham radio be our last antenna standing during a chaotic catastrophe? “Hams” talk about their ability to keep information flowing during a storm. Meanwhile, a very recent technology, artificial intelligence, is playing a growing role in hurricane preparedness. Emergency responders tell us how they use AI to issue warnings, describe the limits of the technology, and why – and when – humans should step in. Guests : Bobby Graves – Network manager for Hurricane Watch Net amateur radio. His call sign is KB5HAV. Julio Ripoll – A coordinator and founder of the National Hurricane Center amateur radio station, WX4NHC in Miami, Florida where he has been a volunteer for 45 years. Matt Anderson – Call sign KT5KNZ, volunteer at the Louisiana State Emergency Operations Center for two decades. He was active during hurricane Katrina. Todd Devoe – Emergency management coordinator for the city of Inglewood, California. Brian Head – Chair of the fire rescue law enforcement and military track for the National Hurricane Conference; executive director with Buffalo Computer Graphics, former employee with the New York State Emergency Management Office.

58:18

In the twenty years since Hurricane Katrina devastated the Gulf Coast, powerful hurricanes such as Sandy, Irma, Maria and Helene have caused immense property destruction and led to thousands of deaths. If Katrina taught us anything, it was to be prepared for the unimaginable. But have we learned that lesson? In this episode, part of a series tied to the 20th anniversary of Katrina, we report from the National Hurricane Conference in New Orleans about what we’ve learned in the years since. Emergency management teams from the Virgin Islands reflect on the two Category 5 hurricanes that hit within just two weeks of each other in 2017, scientists describe how climate change is reshaping hurricanes and our new tools for forecasting them. Meanwhile dark clouds are gathering. As we head into hurricane season, the administration proposes to slash funding for agencies that are tasked with helping us prepare and recover from natural disasters, such as NOAA and the National Weather Service. Guests : Yvette Henry – Community Affairs Coordinator at the Department of Human Services in the US Virgin Islands Abigail Hendrick s – Emergency Support Function #6 coordinator on the island of St John, Virgin Islands Meaghan Enright – executive director of the nonprofit, Love City Strong that works on disaster preparedness, response, and recovery on the island of St John, Virgin Islands Rebeca Mueller – Director of media coordination, National Hurricane Conference Michael Brennan – Director, National Hurricane Center, Miami, Florida Julie Roberts – Former director of communications and Deputy Chief of Staff for NOAA during the first Trump administration.

Touching a Nerve 54:00

לפני 5 weeks54:00

54:00

Some call it your sixth sense. You refer to it when you have a “gut feeling.” With a vast fiber network running throughout your body, the vagus nerve knows about and helps regulate every critical function in it, from heart rate to digestion to your immune system. Now bioelectric medicine is tapping into that bodily omniscience by using tiny electrical pulses on the vagus nerve to help treat diseases as diverse as epilepsy, diabetes, stroke, Parkinson’s, and even depression. In the coming months, the FDA is set to make a decision about a vagus nerve stimulation device, which, if approved, could provide first-of-its-kind treatment for an autoimmune disease that affects millions of Americans. We consider the groundbreaking potential of vagus nerve stimulation and ask whether electricity could one day replace medications. Guest : Kevin Tracey – Neurosurgeon, president of the Feinstein Institutes for Medical Research at Northwell Health, and author of “ The Great Nerve: The New Science of the Vagus Nerve and How to Harness Its Healing Reflexes ” Featuring music by Dewey Dellay and Jun Miyake You can get early access to ad-free versions of every episode by joining us on Patreon .

NASA Under the Axe 54:40

54:40

The White House has proposed unprecedented cuts to NASA’s budget - the largest in the agency’s history. If approved, this withdrawal of funding would force the cancellation of many major programs, including the long anticipated Nancy Grace Roman Space Telescope as well as others involved in the search for life in the universe. It would also impact the agency’s ability to do fundamental research. We look at what the loss of NASA programs could mean for the future of space science and exploration. Plus, an intriguing discovery by the James Webb Space Telescope underscores the progress we’ve made - and could lose - when it comes to searching for potential biosignatures in the universe.

By one estimate the average American home has 300,000 objects. Yet our ancient ancestors had no more than what they could carry with them. How did we go from being self-sufficient primates to nonstop shoppers? We examine the evolutionary history of stuff through the lens of archeology beginning with he ancestor who first picked up a palm-sized rock and made it into a tool. Guest : Chip Colwell - archeologist and former Curator of Anthropology at the Denver Museum of Nature & Science, editor-in-chief of the digital magazine Sapiens, and author of “ So Much Stuff: How Humans Discovered Tools, Invented Meaning, and Made More of Everything .” Featuring music by Dewey Dellay and Jun Miyake Originally aired February 5, 2024 You can get early access to ad-free versions of every episode by joining us on Patreon .

With planets and moons, it’s what’s inside that counts. If we want to understand surface features, like volcanoes, or their history, such as how the planet formed or whether it’s suitable for life, we study their interiors. Astronomer Sabine Stanley takes us on a journey to the centers of Venus, Saturn’s large moon Titan, Jupiter’s moon Io, and of course Earth, to help us understand how they, and the solar system, came to be. Guest: Sabine Stanley - Planetary scientist at Johns Hopkins University and the author of What’s Hidden Inside Planets.

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 humans in the loop.

Skeptic Check: Cryptids 56:36

56:36

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 the Flying Spaghetti Monster are so strange, it challenges us to separate fauna fact from folktale. Guests : Chris Rogers – Assemblymember, California’s 2nd Assembly District Benjamin Radford – Deputy Editor of Skeptical Inquirer Science Magazine, author, and co-host of Squaring the Strange podcast Michael Branch – Writer, humorist, and author of On the Trail of the Jackalope: How a Legend Captured the World’s Imagination and Helped Us Cure Cancer Boris Worm – Marine ecologist, Professor of Biology at Dalhousie University in Halifax, Nova Scotia Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.

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 Car Timothy B Lee – Technology journalist and writer of the newsletter, Understanding AI Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.

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.

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 Health John Green – Author of The Fault in Our Stars , The Anthropocene Reviewed , and Everything is Tuberculosis: The History and Persistence of our Deadliest Infection Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.
