Science for the People

Science for the People is a long-format interview podcast that explores the connections between science, popular culture, history, and public policy, to help listeners understand the evidence and arguments behind what's in the news and on the shelves. Our hosts sit down with science researchers, writers, authors, journalists, and experts to discuss science from the past, the science that affects our lives today, and how science might change our future.

In the book Crossings: How Road Ecology Is Shaping the Future of Our Planet, journalist Ben Goldfarb details how roads have transformed our world. On this week’s show, Ben shares insights from his reporting on the science of studying how roads interact with animals and ecosystems. He recounts tales of tallying roadkill, scooping up stranded frogs, and visiting the roadkill capital of the world. Along with discussing the problems wrought by roads, Ben shares how efforts to help animals, such as wildlife crossings, have fared. And we talk about what roads reveal about people and our societies. 

We all know that climate change is coming for us. It's already here. But it's really, really hard to change people's actions, especially when those actions don't benefit the here and now, but matter most for the future. They require long views of time, the ability to not just imagine, but to care about people in the future. Why don't we do that now, and how do we get there? We're talking with Richard Fisher, author of The Long View: Why We Need to Transform How the World Sees Time.

Ice is one of those invisible little gears of the modern, westernized world. We don't notice it when we have it, and as soon as we can't get it we find ourselves desperate to get it back. It wasn't always like this: ice started as a luxury of more northern climates, and the story of how it became more ubiquitous -- including in southern climates where natural ice is rare to non-existant -- is a fascinating one. We speak to writer and author Amy Brady about her new book "Ice: From Mixed Drinks to Skating Rinks - a Cool History of a Hot Commodity" and learn about the origins of our modern obsession with and dependency on ice.

You are what you eat, right? Well then, who were the ancient Romans, and who were the people they colonized? And who are we? And why do we eat so much chicken? This week we're sitting down with Silvia Valenzuela Lamas to talk about how Roman colonization changed both the animals people raised and how people ate them. We're also talking with Richard Thomas about chickens, and how our taste for it may be one of the most enduring things we leave behind.

In his book Tenacious Beasts, philosopher and writer Christopher Preston explores creature comebacks. Some of these stories highlight the evolutionary advantages that animals have racked up over millennia, while others are marked by intensive human intervention. Along the way, Preston opens some big questions about conservation dilemmas, such as what to do when helping one species means harming another. Amidst the bad news about biodiversity loss, Tenacious Beasts brings snippets of hope and lessons learned from animals such as beavers, bison and humpback whales. On this week’s show, Christopher shares about these animal recoveries, insights collected from Indigenous communities and scientific research, and what coexisting with wildlife means for humans and our societies.

A lot of us learned basic ecology in primary school. Maybe we took a biology class in high school or secondary school and dug in a little more. We use terms like "niche" but do we really know what they mean? How much complexity does that little word cover, if you start to unpick it? We are joined by Tim Blackburn, Professor of Invasion Biology at University College London and author of the book "The Jewel Box: How Moths Illuminate Nature's Hidden Rules", where he combines his years of working in the field of ecology with his love for catching moths, and helps us understand the many, many layers of complexity at work in the ecosystems around us.

Birds carry out some of the most amazing feats of athleticism in the world. Hummingbirds cross the entire Gulf of Mexico, their tiny wings beating continuously for three days straight. A single bird will fly across the entire Pacific ocean in one go. What do we really know about bird migration, and how do we know it? This week we're talking with Rebecca Heisman about her new book: Flight Paths: How a Passionate and Quirky Group of Pioneering Scientists Solved the Mystery of Bird Migration.

In 1938, two botanists, Elzada Clover and Lois Jotter, made an ambitious voyage down the Colorado River driven by the desire to chronicle the plant life of the American Southwest. In her new book Brave the Wild River, science journalist Melissa Sevigny traces their expedition through the Grand Canyon, which led them through seething rapids and the occasional mishap. Journalists of the day gawked at their gender and the pair were forced to pick up chores labeled as “women’s work." Still, they managed to collect hundreds of plants that hadn't yet been catalogued by researchers. Their observations about desert ecosystems were notable even decades later, as scientists looked to them to learn about how dams had changed the Colorado. Sevigny joins us this week to share the botanists' story and the reporting behind it.

Humans are a roaming species. We've been traveling from continent to continent since our very earliest evolution. In fact, we've been doing it even before we were humans. This week, we're talking with archaeologist Radu Iovita about the ancient silk road, a travel network that was in use tens of thousands of years ago, and we speak with archaeologist Elroy White and anthropologist Alisha Gauvreau about what the oral histories of Indigenous people have to say about North American settlement and how archaeologists are working with First Nations to confirm those histories.

Is there an insect more universally despised than the wasp? What have they done to incur so much of our ire? No one likes them. Well... almost no one. Seirian Sumner, Professor of Behavioural Ecology at University College London and cofounder of the Big Wasp Survey, is on a mission to improve the wasp's PR with her book "Endless Forms: Why We Should Love Wasps". She joins us to talk about the fascinating biology and behaviour of wasps and their societies, and how we can learn to better coexist with the wasp, thinking of it less as pest and more as pest control.
