The Human Network #524

May 17, 2019

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".

Happy As A Clam (Garden) #523

May 10, 2019

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...

Home Alone? #522

May 03, 2019

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".

The Curious Life of Krill #521

April 19, 2019

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 create 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".

Animal Architects #519

April 05, 2019

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...

Life in Plastic, Not Fantastic #517

March 15, 2019

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:... Read More

The Keys to Skeletons Lost #516

March 08, 2019

Until we break a bone or two, we tend not to spend too much time thinking about our bones, where they come from, and how we know what we know about them. Well, today we've got a bone to pick with our own skeletons. We'll talk with Brian Switek, author of the book "Skeleton Keys: The Secret Life of Bone", about where your skeleton comes from, and how so many of the skeletons scientists have studied have complicated pasts and uncertain futures.

Humanimal #515

March 01, 2019

Are humans special? We feel special, like we're somehow different from the rest of life on the planet. But are we really? This week, we spend the hour with Adam Rutherford, science broadcaster, writer, and author of the book "Humanimal: How Homo Sapiens Became Nature's Most Paradoxical Creature - A New Evolutionary History". We discuss the commone ways we think humans are different from other creatures and how, sometimes, those ideas turns out to be not quite correct. Along the way we also think a little more carefully about some of the deeply ingrained and sometimes subtle ideas people have... Read More

All Over The Map #512

February 08, 2019

Today we're talking about maps: why we can spend hours pouring over them, the stories they tell, the information they visualize, and how they border between map and a work of art is a gloriously fuzzy one. We spend the hour with journalists Betsy Mason and Greg Miller, co-authors of a beautiful and fascinating new book "All Over the Map: A Cartographic Odyssey". You can see some of the maps we discuss over at the All Over the Map section of National Geographic. Read More

Ok, you got out the door and did a workout. Excellent work! Now you're sore. Rats. What do you do? Foam roll? Stretch? Stand butt naked in a tank pumping in liquid nitrogen? Put on specially branded pajamas? The recovery options are endless these days. But which of them work best? Heck, which even work at all? We're talking with Christie Aschwanden about her new book: "Good to Go: What the Athlete in All of Us Can Learn From the Strange Science of Recovery".

January 25, 2019

This week on Science for the People: who is driving this genetic bus? We'll talk with Kevin Esvelt about gene drives, what they are, where they come from what they can be used for, and why the science on gene drives should be done as openly as possible. Then, we'll speak with Laurie Zoloth about the ethical questions surrounding their use, why people are so afraid, and who should be making the decision to use this technology in the wild.

Anisogamy: The Beginning of Male and Female #509

January 18, 2019

This week we discuss how the sperm and egg came to be, and how a difference of reproductive interest has led to sexual conflict in bed bugs. We'll be speaking with Dr. Geoff Parker, an evolutionary biologist credited with developing a theory to explain the evolution of two sexes, about anisogamy, sexual reproduction through the fusion of two different gametes: the egg and the sperm.

Freedom's Laboratory #508

January 11, 2019

Poaching, and We Don't Mean Eggs #507

January 04, 2019

We all know poaching elephants for their ivory and pangolins for their scales is wrong, right? Then why do people keep doing it? We speak with Rachel Nuwer, author of the book "Poached: Inside the Dark World of Wildlife Trafficking", to find out, and figure out what can be done to stop it. And we'll talk with Vincent Nijman about why, when scientists find a new or rare species, they might want to keep that exciting information to themselves.
