The News story ‘Clash of the physics laws’ (Nature 543, 597–598; 2017) failed to give the full name and affiliation of the person quoted at the end. It was a co-author of the 2011 Nature paper, Renato Renner at the Swiss Federal Institute of Technology Zurich. And the News Feature ‘Cancer’s cruel chimaeras’ (Nature 543, 608–611; 2017) should have said that mortuary workers, not paramedics, came to take away Max Ritvo’s body. And the family foundation was directed to focus more of its research spending on basic science, not all of it.
