A Study Exposes the Health Risks of Gene-Editing Human Embryos

Last year, a Chinese scientist tried to give two babies a mutation to protect them from HIV. But that mutation also seems to shave years off people's lives.Kin Cheung/APA missing chunk of DNA, 32 base pairs long and smack in the middle of the CCR5 gene, might be the most studied mutation in human history.…
