Gene-edited babies: no one has the moral warrant to go it alone | Katie Hasson and Marcy Darnovsky

A scientist claims to have created genetically modified humans. This should be of grave concern

The fierce global controversy over whether to alter the genes of future children and generations just got fiercer. On the eve of a high-profile scientific meeting in Hong Kong on human gene editing, the Chinese researcher and biotech entrepreneur He Jiankui announced he had already created genetically modified humans, twin girls born a few weeks ago.

The reckless actions of one scientist cannot and should not pre-empt the global public conversation over whether to proceed with reproductive germline editing, as the procedure is known. In fact, the conversation is now more urgent and necessary than ever. There's a huge amount at stake for all of us.
