The Chinese scientist who created “CRISPR babies,” He Jiankui, sincerely believed that the research violated neither his country’s laws nor the guidelines of the international scientific community, according to his friends and colleagues. He didn’t exactly keep his experiment secret: He told at least four U.S. scientists that he was considering establishing pregnancies with genome-edited IVF embryos, enlisted a U.S. scientist to work at his Shenzhen lab, teamed with a Chinese hospital and IVF clinic, and proudly announced the birth of “Nana” and “Lulu” on YouTube in November.

Though researchers forcefully condemned He’s work as unethical and a breach of a scientific red line — and while the Chinese government has since accused him of breaking their laws — He clearly hadn’t gotten the memo.

Now, in an effort to prevent another He, 18 scientists from seven countries have called for “a global moratorium on all clinical uses of human germline editing” — that is, changing DNA in sperm, eggs, or early embryos to make genetically altered children, alterations that would be passed on to future generations. They say a moratorium should be in place for at least five years.
