The world's deadliest viruses and bacteria – from HIV to swine flu have been reconfigured as delicate glass sculptures by Bristol artist, Luke Jerram. With the help of virologists and glassblowers, Jerram has created a series of works designed to challenge the way viruses – which are naturally transparent – are presented in the media in bold colour for dramatic effect. An exhibition of the glass renderings opens at the Smithfield gallery, London, on 22 September until 3 October
