April 2016 Issue of The Analytical Scientist

Welcome to April’s issue! In Upfronts, we share a new approach for tackling ‘legal highs’ and find out why plucky pigeons are strapping on sensor vests for the good of humankind. Michele Lees asks if analytical scientists can outwit food fraudsters and three experts explain why pesticide analysis is still a hot topic. Power List heavyweight Jonathan Sweedler discusses analytical semantics and his search for answers in neuroscience, while Frank Bright talks about the amazing ‘toolbox’ of analytical science and what defines great research.
