Luca Turin. Portrait of Dr Luca Turin who proposes that a molecule's smell depends mostly on its vibration rather than its shape. This theory could revolutionise the perfume industry. Computer graphics of fragrant pentadecanolide molecules surround him. Turin, of the Department of Anatomy & Developmental Biology at University College London, Britain, has designed a computer algorithm which can determine how a human nose will perceive the smell of any molecule. Turin is setting up a database of molecules which will allow perfume manufacturers to design new fragran- ces much more quickly and cheaply than has previously been possible. Photographed in 1997.
