In Our Time: Science Folgen

Melvyn Bragg and guests discuss the implications of the developments in genetic engineering. Out of the city of Cambridge in the mid century came DNA and out of Edinburgh at the end of the century came the cloning of Dolly the sheep. These two facts might well do more to change the world literally, and our view of the world, than anything else that has happened at any time. Genetics have become the conversation of our day and with the Human Genome Project lumbering towards completion, its power grows. But are the consequences likely to be destructive and will what we think of as a human being, a personality, or even a person, change uncomfortably and irredeemably? With Grahame Bulfield, geneticist, honorary professor, Edinburgh University and Director of the Roslin Institute, Edinburgh; Bryan Appleyard, features writer for The Sunday Times and author of Brave New Worlds: Genetics and the Human Experience.

Melvyn Bragg and guests marvel at our brains and discuss how at the end of a century of research we still understand so little about how they work.Developments in the understanding of the brain represent one of the major leaps forward in science in the 20th century, and the research is gathering pace and intensity. It’s a subject which captures the imagination, particularly the search for consciousness whatever that might be, and brings together some of the newest technology and the oldest belief systems. What a piece of work is the brain - a grain-of-sand-sized piece contains one hundred thousand neurons, two-million axons and one billion synapses which all talk to each other. How far we have got with our understanding of the brain and what can it tell us about ourselves and the world we live in?With Professor Susan Greenfield, director of the Royal Institution, Professor of Pharmacology, Oxford University and Professor of Physics at Gresham College; Professor Vilayanur Ramachandran, Professor of Neuroscience and Psychology, Director of the Brain Perception Laboratory, University of California in San Diego and Professor at the Salk Institute.

Melvyn Bragg and guests discuss how our increased knowledge of the functioning of the brain and the mechanisms of memory in the 20th century has changed our feelings about our own natures, and our approach to the behaviour and treatment of others.Many questions have been thrown up this century by our growing knowledge about how the brain and the mind function. How easy is it to establish the relationship between the two, and what light can this relationship throw on our understanding of our own and others natures? With Steven Rose, Professor of Biology and Director of the Brain and Behaviour Research Group, Open University, Dan Robinson, Distinguished Research Professor, Georgetown University and visiting lecturer in Philosophy and Senior Member of Linacre College, Oxford University.
