A group of engineers from MIT have created analog calculators out of living cells, according to a paper published online in Nature yesterday. By tweaking the genes of bacterial cells, the researchers were able to create circuits that can perform calculations - including division, multiplication, logarithms and square roots - in a much more efficient way than many existing biocomputers.
