Royal Institution Christmas Lectures - Life Fantastic (2013) Part 3 Could I Live Forever?

Dr Alison Woollard explores the frontiers of developmental biology.

Part 3: Could I Live Forever?

Dr Alison Woollard tackles a question that has intrigued scientists and natural philosophers for centuries - why do we die? The cycle of life and death affects all cells, but Alison reveals a shocking truth: that 'cell death' plays an important part in life. It enables the development and survival of most multi-celled organisms from hedgehogs to humans. Why does a mayfly's life last just a few minutes when an elephant can live for 80 years? Developmental biology and genetics give us new insights into how cells work and how we can use this knowledge to improve or even extend our lives. Some animals, like the naked mole rat, are well on the way. Alison artificially 'ages' the audience using a computer program and meets a patient who has had their eyesight restored with cutting-edge stem cell therapy. Joining Alison to discuss the serious ethical implications of such medical and scientific advances is Lord Winston. They confront the potential dangers of tinkering with evolution.
