A scientist in New York is conducting experiments designed to modify DNA in human embryos as a step toward someday preventing inherited diseases, according to an NPR report.
For now, the work is confined to a laboratory. But the research, if successful, would mark another step toward turning CRISPR, a powerful form of gene editing, into a tool for medical treatment.
A Chinese scientist sparked international outrage in November when he announced that he had used the same technique to create the world’s first gene-edited human babies. He said his goal was to protect them from infection with HIV, a claim that was criticized because there are safe, effective and far less controversial ways of achieving that goal.
