This week on Science Weekly with Ian Sample we hear from a leading light in the development of human genetic analysis, Professor Euan Ashley from Stanford University. Ian talks to Euan about his recent research into the cost and diagnostic effectiveness of personal genomic mapping and why we all need to look beyond the hype.
Ian is joined by the Guardian's environment site editor Adam Vaughan and Observer Tech Monthly's commissioning editor Nicola Davis to discuss the recent UK smog alert, why a mind-controlled exoskeleton will be kicking off this year's World Cup tournament in Brazil, and an electronic nose that sniffs out disease.
