The Chinese researcher who stunned and alarmed the international scientific community with the announcement that he had created the world’s first gene-edited babies has been sentenced to three years in prison by a court in China. He Jiankui sparked a bioethical crisis last year when he claimed to have edited the DNA of human embryos, resulting in the birth of twins called Lulu and Nana as well as a possible third pregnancy. The gene editing, which was aimed at making the children immune to HIV, was excoriated by many scientists as a reckless experiment on human subjects that violated basic ethical principles. He was convicted of “illegal medical practice,” sentenced to three years in prison and fined about $430,000, according to the news agency Xinhua. He pleaded guilty, along with two collaborators, Zhang Renli and Qin Jinzhou, who also received prison sentences and fines.
