“We said ‘don’t freak out,’ 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 ‘don’t panic.’ Many years and years of boring bench science remain before anyone could even think about putting it near a woman’s uterus. Well, we might have been wrong. Permission to push the panic button granted.” The scientist who Crispr’d babies bucked his own ethics policy. And today, He Jiankui told a conference that another gene-edited baby may be on the way.
