Researchers took a big step toward creating synthetic life. They transplanted one microorganism's genome into another, completely changing its identity and behavior. The goal down the road is to create a genome and then do the transplant, so the new organism will be man-made. Scientists' spins: 1) We can make bacteria that produce fuel and fight global warming! 2) Don't worry, the bacteria we're using don't cause disease, and we can engineer them to self-destruct if they escape the lab. Rebuttal: Somebody else could use the same techniques to engineer bacteria that do cause disease or wreak some other kind of havoc. (To debate the wisdom of making synthetic life, click here.)
