Chinese scientist who edited babies' genes jailed for three years

He Jiankui was guilty of illegal practices in trying to alter the genetic makeup of twin girls

A Chinese court has sentenced He Jiankui, the scientist who sparked global controversy last year when he claimed to have created the world's first "gene-edited" children, to three years in prison for violating medical regulations.

He shocked the scientific community when he announced at a conference in Hong Kong that he had created genetically modified twin sisters, dubbed Lulu and Nana, and that a third child was on the way.
