Dali, science and surrealism : sperm donation / the sound of cells.

To celebrate the centenary of artist Salvador Dali's birth, Geoff Watts visits Dali Universe and looks at the influences Relativity, Quantum Physics and ripe camembert cheese had on his work. The second item on the programme is a report by Molly Bentley about sperm donation and recent research into infertility treatments. The third item is about cell sounds - in the future could a doctor listen to our bodies to find out what's wrong with is? The final item is about Mystic experiences and what the latest brain scanning techniques can reveal about them.
