Scientist Who Crisprd Babies Bucked His Own Ethics Policy
We said \u201cdon\u2019t freak out,\u201d when scientists first used Crispr to edit DNA in non-viable human embryos. When they tried it in embryos that could theoretically produce babies, we said \u201cdon\u2019t panic.\u201d Many years and years of boring bench science remain before anyone could even think about putting it near a woman\u2019s uterus. Well, we might have been wrong. Permission to push the panic button granted.
