Genome-engineering technologies can rewrite a cell's genome, thus emerging as powerful tools for biotechnology, energy and agriculture. Researchers led by George Church of the Harvard Medical School note that genome-scale editing tools which are fast and easy to use are revolutionary.

"The payoff doesn't really come from making a copy of something that already exists," said Church. "You have to change it—functionally and radically." The change has three goals: (1) add functionality to a cell by encoding for useful new amino acids; (2) introduce safeguards that prevent cross-contamination between modified organisms and the wild; and (3) establish multi-viral resistance by rewriting code hijacked by viruses.

"We're trying to challenge people," Harris Wang, research fellow said, "to think about the genome as something that's highly malleable, highly editable."
