In this July 31 photo provided by Oregon Health and Science University, Shoukhrat Mitalipov, left, talks with research assistant Hayley Darby in the Mitalipov Lab at OHSU in Portland, Oregon. Mitalipov led a research team that, for the first time, used gene editing to repair a disease-causing mutation in human embryos, laboratory experiments that might one day help prevent inherited diseases from being passed to future generations.
