Scientists force viruses to evolve as better delivery vehicles for gene therapy
...guessed those two," Schaffer said. "Using the same algorithm as nature came up with - evolution - to solve the problem, is the best way to do it." Since each generation takes about a month, Schaffer predicted that many types of new and improved strains could be created in a few months' time, and certainly in l...Satellite portrait of global plant growth will aid climate research
