    What happens in your body when you eat
    Dec 20 2024
    What’s your favourite food? A hamburger, a slice of cake, a pizza? Eating is something we all do every day but most of us rarely think about what actually happens in our bodies after we put food into our mouths. In this episode, we catch up with Dr Chris Van Tulleken to speak about his forthcoming Royal Institution Christmas Lecture series telling us everything we need to know about what’s happening in our bodies when we eat. He tells us what actually happens when we put food into our mouths, what’s going on in our bodies once food is in there, and why farting is just part of the process. BBC Four and iPlayer, 9pm, on 29, 30 and 31 December. Learn more about your ad choices. Visit podcastchoices.com/adchoices

    Anyone who has switched on the news even briefly this year will no doubt have seen scenes of extreme flooding occurring in all corners of the globe.

In this episode, we catch up with Prof Trevor Hoey, a hydrologist based at Brunel University, London. He tells us about the various climate mechanisms driving these extreme weather events, how counterintuitively severe droughts are being caused by the same processes and he also details some of the measures we can take to minimise the damage these events cause.

  • The science of manipulation

    The science of manipulation
    Dec 9 2024
    Why do we humans seem to be so easily influenced or even fooled? On one hand this can be done for entertainment, in a Las Vegas stage magic show for example, but on another it can be used for more nefarious purposes such as con artists tricking people into sharing their bank account details. In this episode, we speak to science writer and BBC Science Focus contributor Brian Clegg to talk about his latest book: Brainjacking – The Science of Influence and Manipulation. He tells us how our emotions can make us susceptible to being tricked, the role advances in technology such as AI are increasingly playing in our ability to manipulate others and how the whole phenomenon stems from our love of a good story.

    From the distinctive caw of a crow to the musky scent of a beaver, the world around us is filled with the telltale signs of animals going about their daily business. But how can we teach ourselves to pick up on them more effectively and what can we learn from doing so? In this episode, we catch up with ecologist and author George Bumann to talk about his latest book, Eavesdropping on Animals: What We Can Learn from Wildlife Conversations. He tells us how by simply opening our eyes, ears and noses when we’re out we can begin to tune into to our environment more closely and in turn learn more about the lives and behaviours of the animals we share it with.
