#446 Frogs From the Skin In Nov 03, 2017

Show notes

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.

#445 AI: Ant Intelligence Oct 27, 2017

Show notes

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.

#444 The V-Word (Rebroadcast) Oct 20, 2017

Show notes

This week, we're looking at the social and biological science of female sex organs. 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.

#443 Batteries Oct 13, 2017

Show notes

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.

#442 From Nobel to Ig Nobel Oct 06, 2017

Show notes

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...

#441 Superhuman Sep 29, 2017

Show notes

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.

#440 Weapons of Math Destruction (Rebroadcast) Sep 22, 2017

Show notes

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.

#439 Flooded Sep 15, 2017

Show notes

This week on Science for the People, we take a closer look at what happens when water falls from the sky, how it moves once its on the ground, and what happens when people and water get in each other's way. We talk with Lucy Barker, Hydrological Analyst at the Centre for Ecology & Hydrology, to get us started with some quick Hydrology 101. And we speak with Anne Jefferson, Associate Professor at Kent State University, about the challenges of redirecting water through, under, and around our cities and communities.

#438 Big Chicken Sep 08, 2017

Show notes

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...

#437 Tiny Bubbles, Big Impact Sep 01, 2017

Show notes

This week, we're discussing an effect called cavitation: low pressure causes bubbles of vapour to form in a liquid, which can cause a lot of damage when those bubbles collapse. 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.
