Researchers say they have replaced all the genes of E. coli bacteria with a complete copy of the genome synthesized in the lab. It’s a step toward creating germs that are genetically tailored to make a specific materials such as Kevlar or other polymers. Scientists at the University of Cambridge report in Nature how, in a stepwise fashion,…
