"In research that further bridges the biological and digital world, scientists at the University of California, San Francisco have created bacteria that can be programmed like a computer. Researchers built "logic gates" – the building blocks of a circuit – out of genes and put them into E. coli bacteria strains. The logic gates mimic digital processing and form the basis of computational communication between cells, according to synthetic biologist Christopher A.
Land mines are currently strewn throughout 87 of the world’s countries, and each year they cause 15,000-20,000 new casualties, the vast majority of which are inflicted upon civilians. Sifting through minefields to remove these hidden threats is currently a dangerous, tedious, and expensive process, however scientists at the University of Edinburgh recently announced that they have engineered a strain of bacteria that glows green in the presence of explosives, making mine detection a snap.
