World’s first gene-edited babies created in China, claims scientist

Unconfirmed scientific breakthrough sparks ethical and moral concerns

A scientist in China claims to have created the world's first genetically edited babies, in a potentially ground-breaking and controversial medical first.

If true, it would be a profound leap of science and ethics. This kind of gene editing is banned in most countries as the technology is still experimental and DNA changes can pass to future generations, potentially with unforeseen side-effects.
