A Duke University cancer scientist resigned Friday amid concerns about his research that arose after the university started probing whether he’d lied on a grant application.
School spokeswoman Debbe Geiger also said another researcher at the school is asking the journal Nature Medicine to retract a paper he published with Anil Potti, the scientist who’s stepping down. Potti’s collaborator Joseph Nevins said some of the tests in the research they produced for that paper can not be duplicated.
