In this News Feature, a parenthetical sentence reading “(Although van Deursen left the Minnesota research hospital earlier this year after allegations of bullying, a Mayo Clinic spokesperson states that the integrity of the lab’s results has not been called into question and that no published papers are being retracted),” located at the end of the first paragraph of section “Zombie cells,” has been removed.

The original News Feature has been corrected online.
