If the plan worked, it would be a proof-of-principle for a much larger tallying device(计算装置). The group, from the Federal Institute of Technology (ETH) in Zurich, was one of 17 teams presenting their projects at the first international Intercollegiate Genetically Engineered Machine (IGEM) competition, held at the Massachusetts Institute of Technology (MIT) in Cambridge on 5 and 6 November. The event attracted students from all over the world to design and build machines made entirely from biological components such as genes and proteins. They drew up grand designs for bacte
