When Chinese researchers first edited the genes of a human embryo in a lab dish in 2015, it sparked global outcry and pleas from scientists not to make a baby using the technology, at least for the present.
It was the invention of a powerful gene-editing tool, CRISPR, which is cheap and easy to deploy, that made the birth of humans genetically modified in an in vitro fertilization (IVF) center a theoretical possibility.
The claim that China has already made genetically altered humans comes just as the world‚Äôs leading experts are jetting into Hong Kong for the Second International Summit on Human Genome Editing.
The purpose of the international meeting is to help determine whether humans should begin to genetically modify themselves, and if so, how. That purpose now appears to have been preempted by the actions of He, an elite biologist recruited back to China from the US as part of its ...
