    Why is sunscreen suddenly controversial?
    2025/09/10
    For years, sunscreen was the dullest health advice around: slap it on, don’t burn, lower your cancer risk. Easy. But in the weird world of TikTok wellness hacks and alarmist headlines, SPF has been recast as something sinister. This week on Why, Emma Kennedy is joined by Brian Diffey, Emeritus Professor of Photobiology at the University of Newcastle, to unpack how sunscreen actually works and how a simple life-saving habit got tangled up in conspiracy and misinformation.

    2025/08/13
    We’re back and we’ve got some questions. Evolution has shaped us into the odd-looking, brilliant creatures we are, but how exactly did it do it? Why did our genetics settle on five fingers?

    How is Ozempic changing the world?
    2025/07/30
    We’re back and we’ve got some questions. Weight-loss injections are reshaping more than waistlines. They’re changing the world we live in. Drugs like Ozempic were developed to treat diabetes, but now they’re transforming how we eat, fly, dress and maybe how we think about our impulses. This week, Emma Kennedy is joined by Professor Giles Yeo, obesity researcher at Cambridge University and author of Why Calories Don’t Count: How we got the science of weight loss wrong, to help us wrap our heads around how these so-called “skinny jabs” are changing everything. Buy Why Calories Don’t Count: How we got the science of weight loss wrong through our affiliate bookshop and you’ll help fund The Bunker by earning us a small commission for every sale.
