As a genome editing summit opens in Hong Kong, questions abound over China, and why it quietly bowed out

Quoted: Law professor and bioethicist R. Alta Charo of the University of Wisconsin, Madison, a member of the summit organizing committee, thinks that’s the right emphasis. “We continue to have a public fascination with the least likely applications” of CRISPR, she said: “Germline editing, which will be the most complicated use to evaluate in terms of its risks and benefits, and enhancement” — using CRISPR not to treat a disease but to improve someone’s appearance, strength, or other traits. People, she added, put these applications together — germline editing for enhancement, a.k.a. “designer babies” — “and we’re off to the races.”
