Glow worms, Spider Silk, Light, Raman Spectroscopy and Phototherapy

05 December 2004
Presented by Chris Smith, Helen Scales.

This show is dedicated to the science of light. Professor Robin Clarke, from University College London, joins us to talk about the use of Raman spectroscopy to date paintings and manuscripts, to identify pigments, and spot forgeries. Also in the studio is Professor David Philips, from Imperial College London, who joins us to discuss the therapeutic applications of light including photodynamic therapy for the treatment of cancers, light-therapy for the treatment of neonatal jaundice, and a laser-toothbrush he is currently working on. Also joining us is Ephraim Emery from the New Zealand Waitomo Glow Worm Caves, to explain the science of glow worms, and spider silk expert Dr Uri Gat, from Israel.
