Healthy rivers and riparian ecosystems are teaming with life, but should rivers themselves be considered alive? The question is central to the growing rights-of-nature movement that claims that ecosystems and entities, like rivers, have legal rights. After Ecuador enshrined the rights of nature in its constitution, lawyers employed the new personhood status to stop mining companies from clearing a section of the Los Cedros River and its surrounding biodiverse cloud forest. Granting rivers moral standing comes as over-damming, pollution, and climate change have put them in crisis globally. Writer Robert Macfarlane explores how seeing rivers as living beings rather than just resources – a change he calls “a great act of moral imagination” – could help save our watersheds and rivers, upon which all life depends.  

Guest:

Robert Macfarlane – Writer and Professor of Literature and Environmental Humanities at the University of Cambridge, and author of “Is a River Alive?”

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.

Whales are aliens on Earth; intelligent beings who have skills for complex problem-solving and their own language. Now in what’s being called a breakthrough, scientists have carried on an extended conversation with a humpback whale. They share the story of this remarkable encounter, their evidence that the creature understood them, and how the experiment informs our Search for Extraterrestrial Intelligence. After all, what good is it to make contact with ET if we can’t communicate?

Guests:

Brenda McCowan – Research behaviorist at the University of California Davis in the School of Veterinary Medicine who studies the ecological aspects of animal behavior and communication. 

Fred Sharpe – Whale biologist with the Templeton WhaleSETI Team and field ecologist with Olympic Peninsula Prairies.

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.

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 Hendricks – 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.

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.

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.

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.
