The Life Scientific Folgen

Professor Chris Elliott is something of a ‘food detective’. A Professor of Food Safety and Microbiology at Queen's University Belfast and a founding director of its Institute for Global Food Security (IGFS), his work is all about developing scientific solutions to protect us from contaminated food, be it accidental or criminal.Following the 2013 horse meat scandal – when prepared foods purporting to be made from beef were found to contain undeclared horse-meat – Chris conducted the independent review of the UK food system that brought to light the growing threat of food crime. Since then, his name’s become synonymous with solving cases of food fraud; today he receives regular tip-offs on everything from oregano scams to dodgy potatoes. But as Chris tells Jim Al-Khalili, his team at the IGFS are pioneering new techniques to read the molecular fingerprint of foodstuffs, with technology that they hope will stop the fraudsters in their tracks…Producer: Lucy Taylor

What use to science is a pesky organism that feeds on rotting fruit? Professor Bambos Kyriacou has spent fifty years observing the behaviour of fruit flies. He keeps them in the lab and in his garden in their thousands, has recorded fruit fly courtship songs using a microphone loved by Jonny Carson (because it made his voice sound deeper) and invented equipment to keep track of their sleeping patterns. He tells Jim Al-Khalili how fruit flies sparked his interest in genetics and how experiments with insomniac fruit flies opened our eyes to the fundamental importance of body clocks.

Leon Barron monitors pollution in our rivers, keeping tabs on chemicals that could be harmful to the environment and to our health. He’s also gathered intelligence on the behaviour of millions of Londoners by studying the water we flush down the loo. His analysis of sewage revealed, for example, just how much cocaine is consumed in London every day. And he’s helped the Metropolitan Police to crack crimes in other ways too, inventing new chemistry tools that can be used by forensic scientists to uncover clues. At school he had no idea he wanted to be an analytical chemist but a short work experience placement at the fertiliser factory convinced him that this kind of detective work was fun.
