‘They don’t want me to rise again’: China’s gene-editing scientist on why he’s back in the lab

Before he agrees to be interviewed, He Jiankui has one request: that he is introduced as a ‘gene editing pioneer’. This may come across as grandiose, but it is also indisputable. No one else in history, after all, can say they have created genetically edited human beings.
