The leading U.S. scientific organization, responding to concerns expressed by scientists and ethicists, has launched an ambitious initiative to recommend guidelines for new genetic technology that has the potential to create "designer babies."
The technology, called CRISPR-Cas9, allows scientists to edit virtually any gene they target. The technique is akin to a biological word-processing program that finds and replaces genetic defects.
The technique has taken biology by storm, igniting fierce patent battles between start-up companies and universities that say it could prove as profitable and revolutionary as recombinant DNA technology, which was developed in the 1970s and '80s and launched the biotechnology industry.
