Long before the claim of the world’s first gene-edited babies became public, Chinese researcher He Jiankui shared the news with a U.S. Nobel laureate who objected to the experiment yet remained an adviser to He’s biotech company. The revelation that another prominent scientist knew of the work, which was widely condemned when it was revealed, comes as scientists debate whether and how to alert troubling research, and the need for clearer guidelines. Emails obtained by The Associated Press under a public records request show that Nobel Prize winner Craig Mello of the University of Massachusetts learned about the pregnancy last April from He in a message titled “Success!” “I’m glad for you, but I’d rather not be kept in the loop on this,” Mello replied.
