The Life Scientific Folgen

Nicky Clayton is Professor of Comparative Cognition at Cambridge University. Her work challenges how we think of intelligence and she says that birds' brains developed independently from humans or apes. Members of the corvid family, such as crows and jays appear to plan for the future and predict other birds behaviour in her elegant experiments.One experiment she has designed was inspired by Aesop's fable of the hungry crow. Her work raises questions about the understanding of animal behaviour, including whether, as humans, we can ever interpret the actions of other species accurately. But she says her research with birds and other animals can help illuminate young children's activities and how their brains develop. Nicky Clayton is scientist in residence at the Rambert Dance Company and her latest collaboration with Mark Baldwin, the artistic director, is "Seven for a secret, never to be told" which takes concepts from childhood behaviour and reinterprets them choreographically.

Jim al-Khalili talks to a scientist who grows human bones in a test tube, Molly Stevens. Molly Stevens does geeky hard core science but her main aim is to help people. Twenty years ago, nobody thought it was possible to make human body parts in the laboratory, but today scientists are trying to create almost every bit of the body. Professor Molly Stevens grows bones. Towards the end of her PHD, a chance encounter with the founding father of tissue engineering and an image of a little boy with chronic liver failure, convinced her that this was what she wanted to do. Ten years on, she runs a highly successful lab at Imperial College London and has been photographed by Vogue. Producer: Anna Buckley.

Colin Blakemore is a neuroscientist who nearly became an artist. He specialised in vision and the development of the brain, and pioneered the idea that the brain has the ability to change even in adulthood contrary to the popular view at the time.Professor Blakemore, the youngest ever Reith Lecturer, is an influential science communicator and is committed to raising the profile of brain research. Because of his work he was targeted by animal rights campaigners for over a decade, but rather than keeping a low profile as advised, he decided to work with the activists and explain his point of view about the need for animal testing in medical research. He was appointed head of the Medical Research Council in 2003 but threatened to resign shortly after when he was refused a knighthood, because of his defence of animal research. He has been equally outspoken on many issues including classification of drugs and GM foods. His current areas of research include how the brain develops which has implications for many conditions including autism and schizophrenia. He talks to Jim Al-Khalili about why he's not been afraid to stand up to his critics. Producer: Geraldine Fitzgerald.
