    Collagen Peptides: Should You Take Them?
    Oct 8 2026
    Collagen peptides!! Can they make you look younger and be healthier? It feels like everyone wants to be bursting with collagen, and apparently the way to do it is by scooping up that white powder of collagen peptides and guzzling it down. Do that, and — according to the wellfluencers — not only will your skin be as bouncy as a baby's bottom, but you'll also be stronger and you'll heal from injuries faster. But of course, not everyone is on the collagen train. There are the collagen haters, who say that eating collagen is a load of baloney. So who's right? To find out, we talk to dietetics Professor Clare Collins, dermatologist Dr. Natalia Spierings, exercise physiologists Professor Luc van Loon and Professor Keith Baar, neutromuscular physiologist Dr. Robert Erskine, as well as sports performance consultant Dr. Dana Lis.

    Why We Never Forget Our Teen Years, with Lisa Damour
    Oct 1 2026
    Our brains go completely WILD when we go through our teenage years. It’s a time where it feels like every disagreement with our parents turns into World War III, and every idea that could get us killed sounds like the most fun we could ever have. In this episode, we get into the science of what the brain is doing during the teenage years with clinical psychologist Dr. Lisa Damour. Lisa co-wrote the college textbook “Abnormal Psychology” and was a consultant on Disney's “Inside Out 2.” She takes us deep into the developing brain to explain what makes teens tick. Plus, we talk about mental health, how boys and girls are struggling in different ways, and tips for anyone who has big feelings.

  • Stress: The Science of Chilling Out

    Stress: The Science of Chilling Out
    Sep 24 2026
    Stress! We’re all feeling it. And besides just feeling crappy, we’re also told that stress can wreak havoc on our bodies. The internet has a million solutions: vagus nerve stimulators, deep breaths, or a hot sauna! If that doesn’t work, maybe a cold plunge? But what does the science say about all this — what works to lower our stress? And is it really THAT bad to be stressed out? We dive into the research to find out, with psychology Professor Mark Seery, psychology Professor Jeremy Jamieson, and anatomist Dr. Theresa Larkin. Find our transcript here: https://tinyurl.com/ScienceVsStress In this episode, we cover: (00:00) We’re all stressed out! (02:37) Is stress that bad for us? (13:55) A healthier stress response (22:32) How our vagus nerves are involved in stress (25:57) Can we “hack” our vagus nerves? (30:42) What else can relieve stress?

  • Could AI Really Kill Us All?

    Could AI Really Kill Us All?
    Sep 17 2026
    Could artificial intelligence really wipe out humanity? Claims that AI poses an existential threat are going gangbusters. AI agents from OpenAI recently hacked into another company, Hugging Face, which has people talking about whether AI can go “rogue.” And some current and former AI company employees are raising the alarm. CEOs have called for a slowdown, and one Anthropic employee just quit, saying that the companies creating this tech are putting us all at risk — and adding that “the people building AI earnestly believe that it could kill us all by the end of the decade.” So — are we really creating a monster? Could AI escape human control and take us all out? If so … how?! And are these scary claims just a distraction from the stuff that AI is already being used for out in the world? We talk to cyber security expert Professor David Parry, philosopher Dr. Nick Bostrom, and scientist Dr. Michael Vermeer to find out.

  • Where Have The Insects Gone?? With Dr. Jessica Ware

    Where Have The Insects Gone?? With Dr. Jessica Ware
    Sep 10 2026
    Bugs are disappearing at alarming rates, scientists are telling us. Bees, butterflies, beetles: all of them have been dropping like flies. And scientists say there are a bunch of reasons to care about this — for example, fewer bugs means less pollination, which means less pasta in your pantry. But recently, some have suggested that all these scientists crying out about the insect apocalypse might just be crying wolf. They say that the math isn’t math-ing and that the insects are doing all right. And this has been bugging us! So we called up Dr. Jessica Ware, an entomologist and a curator at the American Museum of Natural History, to find out what’s going on here. And Jessica also specializes in dragonfly lovemaking, so of course, we had to ask about that too.

  • Protein-Maxxing: Is It Actually Bad For Us?

    Protein-Maxxing: Is It Actually Bad For Us?
    Sep 3 2026
    Protein is everywhere — tons of us are trying to cram more of it into our diets, and it's showing up in our lattes, our snack bars, even our popcorn. But just as we’re getting on board with protein-maxxing, a bunch of headlines have started saying the opposite: that eating LESS protein could actually help you live longer. So what's going on here?? Should we be piling on the protein — or pulling back? And could going too low actually be dangerous? We talk to biologist Prof. Dudley Lamming and exercise physiologist Prof. Stuart Phillips to find out. Note: This episode mentions calorie restriction.

    Sunscreen: Could It Be Toxic??
    Aug 27 2026
    Sunscreen is supposed to protect us from dangerous stuff like cancer, but all over social media, people are saying that we’ve been getting it all wrong. We’re being told that our sunscreen is full of toxic chemicals, that wearing it could mess with our vitamin D levels — even that sunscreen itself actually increases our risk of skin cancer. So, what can the science tell us here? Should we toss our SPF-filled creams and sprays in the bin?? And could the answer here be different depending on your skin tone? We talk to researchers Dr. Brandon Adler, Prof. Rachel Neale, and Dr. Adewole Adamson to find out.
