Scientist who gene-edited babies is back in lab and ‘proud’ of past work despite jailing

He Jiankui, the Chinese scientist infamous for his involvement in the controversial gene-editing of babies, has resurfaced in the scientific community, this time with a focus on researching treatments for genetic diseases such as Alzheimer's. In a recent interview with a Japanese newspaper, He revealed that he has returned to his laboratory and resumed research on human embryo genome editing, despite the ethical and legal fallout from his previous actions.

He Jiankui's name became synonymous with controversy when it was revealed that he had used the gene-editing tool Crispr-Cas9 to modify the DNA of embryos, resulting in the birth of genetically edited twins named Lulu and Nana. He was subsequently sentenced to three years in prison by a Chinese court for violating medical regulations and forging documents related to his research.

Despite the backlash and legal repercussions, He remains steadfast in his defense of his work, asserting that he is "proud" of his role in creating Lulu and Nana. He now aims to leverage genome editing to develop treatments for rare genetic diseases, emphasizing that he will adhere to both domestic and international regulations in his research.

He Jiankui's renewed focus on genetic research comes with a belief that society will eventually come to accept human embryo gene editing as a means of combating genetic diseases. However, his past actions have left a lasting impact on the scientific community, sparking debates about the ethical boundaries of genetic manipulation and the need for stringent oversight in research involving human subjects.

As He Jiankui continues his work in the laboratory, his story serves as a cautionary tale about the ethical complexities and potential consequences of advancing technologies like gene editing. Only time will tell how society grapples with the implications of his pioneering but deeply controversial research.
