Chinese researcher He Jiankui, who claims he helped create the world’s first genetically edited babies, revealed that a second potential pregnancy is in its early stages. The American-trained scientist defended his work at a conference in Hong Kong, saying he was proud of altering the genes of twin girls so they cannot contract HIV. His claims have not been independently verified.
