Annual meeting of British Association's Festival of Science, this year hosted by the University of York, where the first Festival was held. International scientists discuss their latest research with a public audience. Topics covered include a proposed seven-point code for all scientists, examining ancient documents with the diamond synchatron that uses focused beams of light as a giant microscope, low-adhesion non-sticky chewing gum, and the security implications of how hard it is to recognise strangers from their photographs.
