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.
