Face Recognition and Identity #452

December 15, 2017

This week we deep dive into the science of how we recognize faces and why some of us are better -- or worse -- at this than others. We talk with Brad Duchaine, Professor of Psychology at Dartmouth College, about both super recognizers and face blindness. And we speak with Matteo Martini, Psychology Lecturer at the University of East London, about a study looking at twins who have difficulty telling which one of them a photo was of.

Sing a Little Song #450

December 01, 2017

How do we talk? And how do we sing? Most of us walk around making sound all day without any real idea of how we do it. We'll speak with vocologist Ingo Titze about how the human voice sings, the parts of a human singing voice, and more. We'll also speak with Tecumseh Fitch about why we talk... but monkeys don't. The reason? They've got the voice, but not the brains. We've even got some creepy recordings. Related links: Ingo's tips for tired voices: grab a straw!

Frogs From the Skin In #446

November 03, 2017

Pictures of poison frogs are a popular form of home decor. Tiny size, bright colors, super deadly, they've got it all. But how exactly do poison frogs avoid poisoning themselves? This week we talk with Rebecca Tarvin and Cecilia Borghese, two scientists who studied how poison frogs survive their own toxins. And we speak with Sandra Goutte, a herpetologists who studies frog ears, how they work, and whether one tiny, adorable pumpkin toadlet can hear itself talk. This episode is hosted by Bethany Brookshire, science writer from Science News. Read More


AI: Ant Intelligence #445

October 27, 2017

This week we look at why ants seem to act much smarter in groups than on their own, and how we can study their swarm intelligence using robots. We'll be speaking with Stephen Pratt, associate professor in the School of Life Sciences at Arizona State University, about how ants in a colony work together to look for things they need, like nest sites and food. Then we'll speak with Simon Garnier, assistant professor in the Department of Biological Sciences at the New Jersey Institute of Technology, about ants that can make living structures out of their own bodies. Read More

We'll talk to Dr. Anthony Atala, director of the Wake Forest Baptist Medical Center Institute for Regenerative Medicine, about the creation and use of lab-grown vaginas. Biology professor Marie Herberstein exposes the bias against female genitalia in scientific studies. And science writer Emily Anthes tells us about the history and promising future of female condoms.  Read More


Batteries #443

October 13, 2017

This week on Science for the People we take a deep dive into modern batteries: how they work now and how they might work in the future. We speak with Gerbrand Ceder from UC Berkeley, about the most commonly used batteries today, how they work, and how they could work better. And we talk with Kathryn Toghill, electrochemist from Lancaster University, about redox flow batteries and how they could help make our power grids more sustainable. Read More


From Nobel to Ig Nobel #442

October 06, 2017

The Nobel prizes are, well, the Nobel prize of prizes! One of the most elite prizes in the world. But where did they come from, why do they matter, and how do they influence the practice of science? This week we speak with medical historian Nils Hansson and sociologist of science Harriet Zuckerman about the origin and legacy of the Nobel Prizes, and what might help them be more representative of science in the future. And then we talk with Marc Abrahams about another prize, the Ig Nobel prizes, which are supposed to make us laugh, and then think. Related... Read More


Superhuman #441

September 29, 2017

This week we take a closer look at people with brain abilities that appear superhuman. We speak with Craig Stark, Professor of Neurobiology and Behavior at the University of California Irvine, about hyperthymesia and people who possess an extremely detailed autobiographical memory. Then we talk with Jamie Ward, Professor of Cognitive Neuroscience at the University of Sussex, about synaesthesia, multi-sensory substitution, and people who see sounds, taste words, and hear colours. Read More


Weapons of Math Destruction (Rebroadcast) #440

September 22, 2017

This week on Science for the People we look at the modern, inventive ways we try to use math and algorithms to make better decisions, and what happens when those solutions cause more problems than they solve. We speak with Cathy O'Neil about her book Weapons of Math Destruction: How Big Data Increases Inequality and Threatens Democracy and the increasingly opaque and unregulated algorithms that are creeping into our lives. We also talk with David Robinson, co-founder and principal of the think tank Upturn, about their report on the current use of and evidence behind Predictive Policing. Read More


Flooded #439

Big Chicken #438

September 08, 2017

We eat a lot of chicken. But we didn't used to. What changed? In part, what changed was the discovery that antibiotics could build a bigger, better chicken. Now, the big chicken may be suffering the results of too much medicine. This week, we hear from science journalist Maryn McKenna about her new book "Big Chicken: The Incredible Story of How Antibiotics Created Modern Agriculture and Changed the Way the World Eats." We'll also hear from zoonotic disease specialist Tara Smith about the challenges scientists face trying to get out of the lab and into the pigpen. This episode is... Read More


Tiny Bubbles, Big Impact #437

September 01, 2017

First up is Paul Brandner, Associate Professor and Research Leader of the Cavitation Research Laboratory at the Australian Maritime College, to discuss how these bubbles form and why they can be so destructive. And we talk with Suzanne Cox, artist, scientist, and engineer, to discuss her work with crustaceans who have evolved ways of controlling the effect when they strike snail shells.
