Animals Like Us (rebroadcast)

6/29/2020
Laughing rats, sorrowful elephants, joyful chimpanzees. The more carefully we observe, and the more we learn about animals, the closer their emotional lives appear to resemble our own. Most would agree that we should minimize the physical suffering of animals, but should we give equal consideration to their emotional stress? Bioethicist Peter Singer weighs in. Meanwhile, captivity that may be ethical: How human-elephant teamwork in Asia may help protect an endangered species. Guests: Frans...

Let's Stick Together (rebroadcast)

6/22/2020
Crowded subway driving you crazy? Sick of the marathon-length grocery store line? Wish you had a hovercraft to float over traffic? If you are itching to hightail it to an isolated cabin in the woods, remember, we evolved to be together. Humans are not only social, we’re driven to care for one another, even those outside our immediate family. We look at some of the reasons why this is so – from the increase in valuable communication within social groups to the power of the hormone oxytocin....

Skeptic Check: Data Bias (rebroadcast)

6/15/2020
Sexist snow plowing? Data that guide everything from snow removal schedules to heart research often fail to consider gender. In these cases, “reference man” stands in for “average human.” Human bias also infects artificial intelligence, with speech recognition triggered only by male voices and facial recognition that can’t see black faces. We question the assumptions baked into these numbers and algorithms. Guests: Caroline Criado-Perez - Invisible Women: Data Bias in a World Designed for...

Race and COVID

6/8/2020
While citizens take to the streets to protest racist violence, the pandemic has its own brutal inequities. Black, Latino, and Native American people are bearing the brunt of COVID illness and death. We look at the multitude of factors that contribute to this disparity, most of which existed long before the pandemic. Also, how the Cheyenne River Sioux tribe maintained their coronavirus safeguards in defiance of the South Dakota governor. And, the biological reasons why we categorize one...

Soap, Skin, Sleep

6/1/2020
Some safeguards against COVID-19 don’t require a medical breakthrough. Catching sufficient Z’s makes for a healthy immune system. And, while you wash your hands for the umpteenth time, we'll explain how soap sends viruses down the drain. Plus, your body’s largest organ – skin – is your first line of defense against the pandemic and is also neglected because of it. Find out why we're suffering from "skin hunger" during this crisis. Guests: Cody CassidyWho Ate the First Oyster: The...

Gained in Translation (rebroadcast)

5/25/2020
Your virtual assistant is not without a sense of humor. Its repertoire includes the classic story involving a chicken and a road. But will Alexa laugh at your jokes? Will she groan at your puns? Telling jokes is one thing. Teaching a computer to recognize humor is another, because a clear definition of humor is lacking. But doing so is a step toward making more natural interactions with A.I. Find out what’s involved in tickling A.I.’s funny bone. Also, an interstellar communication...

Vaccine, When?

5/18/2020
It will be the shot heard ‘round the world, once it comes. But exactly when can we expect a COVID vaccine? We discuss timelines, how it would work, who’s involved, and the role of human challenge trials. Also, although he doesn’t consider himself brave, we do. Meet a Seattle volunteer enrolled in the first coronavirus vaccine trial. And, while we mount an elaborate defense against a formidable foe, scientists ask a surprising question: is a virus even alive? Guests: Nigel Brown Ian Haydon...

To the Bat Cave

5/11/2020
To fight a pandemic, you need to first understand where a virus comes from. That quest takes disease ecologist Jon Epstein to gloomy caverns where bats hang out. There he checks up on hundreds of the animals as his team from the EcoHealth Alliance trace the origins of disease-causing viruses. But their important work is facing its own threat; the Trump administration recently terminated funding to the Alliance because of its collaboration with Chinese scientists. Hear how Dr. Epstein finds...

Is Life Inevitable? (Rebroadcast)

5/4/2020
A new theory about life’s origins updates Darwin’s warm little pond. Scientists say they’ve created the building blocks of biology in steaming hot springs. Meanwhile, we visit a NASA lab where scientists simulate deep-sea vent chemistry to produce the type of environment that might spawn life. Which site is best suited for producing biology from chemistry? Find out how the conditions of the early Earth were different from today, how meteors seeded Earth with organics, and a provocative idea...

Skeptic Check: Covid Conspiracy

4/27/2020
Nature abhors a vacuum, but conspiracy theorists love one. While we wait for scientists to nail down the how and why of the coronavirus, opportunists have jumped into the void, peddling DIY testing kits and fake COVID cures like colloidal silver. They’ve even cooked up full-blown conspiracy theories about a lab-grown virus. Find out why this crisis has dished up more than the usual share of misinformation and hucksterism, and how these interfere with our ability to navigate it...

Treating the Virus

4/20/2020
Treating the Virus It’s not like waiting for Godot, because he never arrived. A coronavirus vaccine will come. But it is still months away. Meanwhile, scientists are adding other weapons to our growing arsenal against this virus. The development of antibody tests, antibody cures, and antivirals offer hope that we can soon have the tools to battle those who’ve been sickened by the COVID-19 virus while we wait for the inoculation that will prevent it. Guests: Deepta Bhattacharya Mark...

The Other Living World

4/13/2020
Reason for hope is just one thing that ecologist Carl Safina can offer. He understands why many of us turn to nature to find solace during this stressful time. Safina studies the challenges facing the ultimate survival of many species, but also gives a portrait of animals from their point of view. He describes how diverse animals such as sperm whales, bear cubs, macaws, and chickens deal with uncertainty, and assert their quirky individuality while learning to become part of a community. So...

Zombies, Bigfoot, and Max Brooks

4/6/2020
What do a zombie attack and a viral pandemic have in common? They are both frightening, mindless, and relentless in their assault. And both require preparedness. That’s why the author of “World War Z” – a story about a battle against zombies – lectures at West Point. Max Brooks has also recorded a public service announcement with his celebrated father, Mel Brooks, touting the importance of social distancing during the coronavirus pandemic. His newest novel portrays a different assailant:...

Let's Take a Paws

3/30/2020
Humans aren’t the only animals stressed-out by social distancing. Narwhals send out echolocation clicks to locate their buddies and ease their loneliness. And a plant about to be chomped by a caterpillar knows that the world can be a scary place. In this episode, from dogs to narwhals to plants, we put aside human-centric stories to find out how other living creatures map their world, deal with stress, and communicate.

How Bad Does It Have to Get?

3/23/2020
“Climate change at warp speed” is the way one scientist described the coronavirus outbreak. In a show recorded before a live audience at the Seattle AAAS meeting, and co-presented with the BBC World Service, we discuss out how politics and psychology lead people to tune out inconvenient scientific findings even when the stakes are high – as well as what we can do about it.

It's In Material [rebroadcast]

3/16/2020
Astronauts are made of the “right stuff,” but what about their spacesuits? NASA’s pressurized and helmeted onesies are remarkable, but they need updating if we’re to boldly go into deep space. Suiting up on Mars requires more manual flexibility, for example. Find out what innovative materials might be used to reboot the suit. Meanwhile, strange new materials are in the pipeline for use on terra firma: spider silk is kicking off the development of biological materials that are inspiring...

Skeptic Check: Pandemic Fear

3/9/2020
Contagion aside, coronavirus is a powerful little virus. It has prompted a global experiment in behavior modification: elbow bumps instead of handshakes, hand sanitizer and mask shortages, a gyrating stock market. Pragmatism motivates our behavior toward the spread of this virus, but so do fear and panic. In 1918, amplified fear made the Spanish Flu pandemic more deadly. Can we identify when we’re acting sensibly in the face of COVID-19, or when fear has hijacked our ability to think...

DecodeHer [rebroadcast]

3/2/2020
They were pioneers in their fields, yet their names are scarcely known – because they didn’t have a Y chromosome. We examine the accomplishments of two women who pioneered code breaking and astronomy during the early years of the twentieth century and did so in the face of social opprobrium and a frequently hostile work environment. Henrietta Leavitt measured the brightnesses of thousands of stars and discovered a way to gauge the distances to galaxies, a development that soon led to the...

Have you adapted to the changing climate? Rising waters, more destructive wildfires, record-breaking heatwaves. Scientists have long predicted these events, but reporting on climate change has moved from prediction to description. There’s no time for dwelling on “we should haves.” Communities and organizations are being forced to adapt. Find out what that means, the role of the new “resilience officers,” and the unique response of Native American cultures. Plus, is the coronavirus outbreak...
