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

China's He Jiankui, who used Crispr to edit genome, says he is working on genetic diseases and suggests human embryo gene editing will one day be accepted

A Chinese scientist who was imprisoned for his role in creating the world's first genetically edited babies says he has returned to his laboratory to work on the treatment of Alzheimer's and other genetic diseases.

In an interview with a Japanese newspaper, He Jiankui said he had resumed research on human embryo genome editing, despite the controversy over the ethics of artificially rewriting genes, which some critics predicted would lead to demand for designer babies".
