Why do so many of us get nervous when public speaking? Communication expert Lawrence Bernstein says the key to dealing with the pressure is as simple as having a casual chat. He introduces the "coffee shop test" as a way to help you overcome nerves, connect with your audience and deliver a message that truly resonates. After the talk, Modupe explains a similar approach in academia called the "Grandma test," and how public speaking can be as simple as a conversation with grandma.

We have an update to our recent episode, Skeptic Check: Drone Panic. If you remember, our guest astronomer Andrew Franknoi recalled the story of Jimmy Carter having seen something mysterious in the sky when he was governor of Georgia in 1969. Astronomers at the time suggested it was likely Venus, as has been the case with other sightings, and for decades that was a widely accepted understanding of what he saw. But there is more to the story, as was brought to our attention by multiple BPS listeners. So, we invited Andrew back to discuss the revised account, and its more satisfying scientific resolution.

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 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.

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

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.

NASA Under the Axe 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.

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.

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.

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.
