Life Without Memory

No bats in the night sky. In this episode of Life Without, Alan Davies imagines a world where bats suddenly disappear. From tiny insect-eaters to fruit bats, what would humanity miss when these remarkable mammals are gone? Alan explores the role bats play in controlling insects, pollinating plants and dispersing seeds. He also examines their surprising social lives, their unusual immune systems, and what they might teach us about disease and ageing. Featuring Professor Kate Jones, Professor of Ecology and Biodiversity at UCL, and Dr Christina Stanley, Associate Professor in Animal Behaviour and Welfare at the University of Chester.

What if, one day, something essential to our world suddenly vanished? No warning. No explanation. Just gone. What happens next? Life Without is a roundtable-style podcast that explores this fascinating and thought-provoking question with insight, evidence-based assumptions and a range of perspectives. Hosted by Alan Davies, each episode brings together 2 guests, scientists, psychologists, economists, sociologists and journalists to discuss the unexpected consequences of losing something vital to our world. Each episode starts with a bold, imaginative question: What would happen if something fundamental—like the moon, salt, sleep, or even something as random as rats—suddenly disappeared from the world? What’s the immediate fallout? How does society cope? And how long would it take before things started unravelling?

What would happen to the world if the USA disappears? In this episode of Life Without, Alan Davies explores a planet earth without the land mass of North America. How would opening up the Atlantic impact us in the UK and what would the disappearance of North American produce and people mean for the rest of the world? This episode features Dr. Anjana Khatwa an award winning Earth Scientist and author, and Tori Tsui, a climate justice activist, author, and mental health advocate. An ITN production for BBC Radio 4

Spring Forward, Fall Back or what if we just didn’t? In this episode of Life Without, Alan Davies looks at how our circadian rhythms would be impacted if we simply stopped changing the clocks. Some scientists have argued to do away with the twice-yearly clock change in order to see some beneficial impacts on our health. So why have some parts of the world adopted this system while places like Russia and Mexico don’t use it at all? This episode features Aarti Jagannath, a leading chronobiologist and Associate Professor at the University of Oxford, and Dr Rebecca Struthers who is a watchmaker, author, historian and Honorary Research Fellow at University of Birmingham.

We all know the importance of sleep, but what happens if we literally can’t? In this episode of Life Without, Alan Davies breaks down how long a world full of sleepy people could function. From memory loss to hallucinations, sleep is keeping all our brains working and our bodies functioning. Without it, we would surely die, but what might happen before we do and has tech found solutions to life without sleep? This episode features Derk-Jan Dijk a expert in sleep and Professor at the University of Surrey, and Dr Sophie Bostock an educator dedicated to the science of sleep and performance.
