CRISPR babies: is this the start of a terrifying new chapter in gene editing? | Vox


The past several years in science have unleashed the CRISPR revolution. CRISPR/Cas9 — or CRISPR, as it’s known — is a tool that allows researchers to attempt to control which genes get expressed in plants, animals, and even humans; to delete undesirable traits and, potentially, add desirable traits; and to do all this more quickly, and with more precision, than ever before. (You can read about how CRISPR works here.)

He, a Stanford-trained associate professor at the Southern University of Science and Technology in Shenzhen, China, was not well known in the field of CRISPR editing.

But he’s claiming a major first: to have used the gene editing technology CRISPR to tweak the DNA of human embryos during in vitro fertilization.
