No new memories. In this episode of Life Without, Alan Davies takes away our ability to form them. We can still live in the moment, but what happens when that moment will not stay with us?

Alan explores different kinds of memory, from knowing how to ride a bike to recalling a personal experience. Can technology, routines and support help us cope? And what might memory loss reveal about how people learn, build relationships and make sense of their lives?

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?
