Summer is coming, and summer means sweat. Why do we sweat so much, and how do we do it? We hear from Yana Kamberov about the evolutionary origins of our sweat glands, and why it's one of the things that makes us mammals. Then we talk about why some (but not all) of our sweat STINKS. We'll speak with Gavin Thomas about the bacteria that give us our BO.

This week we're looking back at a man-made disaster that changed the world: the Chernobyl meltdown. We take a closer look at all the contributing factors that lead the No 4 reactor at Chernobyl to explode and how the Soviet Union's political, scientific, and administrative culture at the time contributed to the disaster. And we'll look at the fallout, the logistics of trying to clean up a radioactive accident where five minutes in the wrong area will literally kill you, and the long-tail disaster recovery efforts. We are joined by Adam Higginbotham, author of the new best selling book "Midnight...

What does a network of humans look like and how does it work? How does information spread? How do decisions and opinions spread? What gets distorted as it moves through the network and why? This week we dig into the ins and outs of human networks with Matthew Jackson, Professor of Economics at Stanford University and author of the book "The Human Network: How Your Social Position Determines Your Power, Beliefs, and Behaviours".

This week we’re discussing clam gardens on the west coast of Canada and the US, and how indigenous people have been actively managing food resources in the area for thousands of years. Clam garden rock walls are thousands of years old, and people have been actively maintaining them up to today, but Europeans and the scientific community ignored their existence for a couple of centuries. We speak with Dana Lepofsky, Professor in the Department of Archaeology at Simon Fraser University, and Nicole Smith, a freelance archaeologist based in Victoria, about clam garden rock walls built into the coast of British...

Do you keep your house clean? Do you think that, maybe with the exception of the dog, you're alone in your home? Well, we hate to tell you this, but you're wrong. Your house is filled with microbes, fungi, bugs and much more. This week, we talk about the life filling you're house with Rob Dunn, a professor at North Carolina State University and author of the book "Never Home Alone: From Microbes to Millipedes, Camel Crickets, and Honeybees, the Natural History of Where We Live".

This episode is hosted by Bethany Brookshire, science writer from Science News.

Krill may be one of the most abundant forms of life on our planet... but it turns out we don't know that much about them. For a creature that underpins a massive ocean ecosystem and lives in our oceans in massive numbers, they're surprisingly difficult to study. We sit down and shine some light on these underappreciated crustaceans with Stephen Nicol, Adjunct Professor at the University of Tasmania, Scientific Advisor to the Association of Responsible Krill Harvesting Companies, and author of the book "The Curious Life of Krill: A Conservation Story from the Bottom of the World".

Update: the previous file had overlapping tracks during the second interview. This has now been fixed. This week we broach the topic of Objectivism. We'll be speaking with Keith Lockitch, senior fellow at the Ayn Rand Institute, about the philosophy of Objectivism as it's taught through Ayn Rand's writings. Then we'll speak with Denise Cummins, cognitive scientist, author and fellow at the Association for Psychological Science, about the impact of Objectivist ideology on society.

Don't make the mistake of thinking that humans are the only species that's mastered architecture. There are bugs out in this world that form huge, self healing structures out of their own bodies. And there are other bugs that form fountains of thousands - all to destroy a pizza in just a few hours. Move over, pirhanas. The black soldier fly larvae are here. This week, we talk to Olga Shishkov and Sulisay Phonekeo about their work studying living animal structures, and what that could mean for how we build and how we deal with our rapidly mounting piles of...

This week we delve into genetic testing - for yourself and your future children. We speak with Jane Tiller, lawyer and genetic counsellor, about genetic tests that are available to the public, and what to do with the results of these tests. And we talk with Noam Shomron, associate professor at the Sackler School of Medicine at Tel Aviv University, about technological advancements his lab has made in the genetic testing of fetuses.

Our modern lives run on plastic. It's in the computers and phones we use. It's in our clothing, it wraps our food. It surrounds us every day, and when we throw it out, it's devastating for the environment. This week we air a live show we recorded at the 2019 Advancement of Science meeting in Washington, D.C., where Bethany Brookshire sat down with three plastics researchers - Christina Simkanin, Chelsea Rochman, and Jennifer Provencher - and a live audience to discuss plastics in our oceans. Where they are, where they are going, and what they carry with them. Related links:...
