Top sports stars can take their pick of the very latest performance-enhancing drugs safe in the knowledge that testing authorities know too little about what pharmaceutical companies are developing, concede Graham Trout and Rymantas Kazlauskas who screened athletes at the 2000 Olympics in Sydney. In this tutorial review, the pair discuss the latest challenges to detection and call for greater co-operation between testing laboratories and drug manufacturers so that screening tests are devised well before new products go on sale.
A new molecular switch that can transmit and process solar energy promises advances in photovoltaics and catalytic reactivity, claims a team of chemists from Germany and the US. Andreas Hirsch and Dirk Guldi and their colleagues created their switch by bringing together a protein, a fullerene and an electrode. Iron at the protein's centre is crucial to the switch's operation; by applying different electrochemical potentials, the iron's redox state changes, turning the device on and off
