  • Nuts and Bolts
    How frequently do you think about fasteners like screws and bolts? Probably not very often. But some of them a storied history, dating back to Egypt in the 3rd century BC. They aren’t just ancient history. They help hold up our bridges and homes today. Join us as we dissect a handful of engineering inventions that keep our world spinning and intact. Guests: Roma Agrawal - structural engineer and author of "Nuts and Bolts: Seven Small Inventions That Changed the World (in a Big Way)" Ron Gordon - watchmaker, New York City Descripción en español Originally aired May 6, 2024 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.

  • What Moves Us
    What physical activity gives you joy? Whether it’s walking, running, dancing or swimming, your body evolved to do it. We are made for movement. But there’s a cost, as anyone with a sore neck or aching back knows. From the tiny muscles in our skin, which raise the hair on our arms, to the intricate mix of bone, blood vessels, and nerves in our neck, natural selection has struck a delicate and sometimes wacky balance between utility and form. In this episode, we explore how parts of the body - our muscles, neck and feet - came to be, and what forces prompted the evolution of efficient yet imperfect bodies. Guests: Kent Dunlap - Professor of biology at Trinity College in Hartford, Connecticut and author of “The Neck: A Natural and Cultural History” Bonnie Tsui - Journalist and author of “On Muscle: The Stuff That Moves Us and Why It Matters” Jeremy DeSilva - Anthropologist at Dartmouth College and author of “First Steps, How Upright Walking Made Us Human” 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.

  • Alien Says What?
    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. Laurance Doyle – Astrophysicist and information theory researcher at the SETI Institute.  Descripción en español.

  • Hurricane Comms
    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.

  • Hurricane Season
    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.
