China’s scientist claims world’s first gene-edited babies

HONG KONG: A scientist in China claims to have created the world’s first genetically-edited babies, a move that would be a ground-breaking medical first but which has generated a barrage of criticism. Chinese university professor He Jiankui posted a video on YouTube saying that the twin girls, born a few weeks ago, had had their DNA altered to prevent them from contracting HIV. The professor, who was educated at Stanford in the US and works from a lab in the southern Chinese city of Shenzhen, said their DNA was modified using CRISPR, a technique which allows scientists to remove and replace a strand with pinpoint precision.
