The CRISPR Babies

In 2018 news broke that a Chinese scientist, He Jiankui, had used CRISPR to edit human embryos, and twin girls had been born as a result. The story set off an explosive bioethical controversy. As gene editing expert Kiran Musunuru put it, "He Jiankui's genetic misadventures were the biggest medical story of the century so far." Both scientists and the public had a lot of questions. What was the unmet medical need that justified the gene editing? Was the science ready for prime time? And, if it was, was He Jiankui the right scientist to do it? Seven years later these questions are far from resolved.
