The News story ‘Who will build the next LHC?’ (Nature 536, 383–384; 2016) should have said that souping up the current LHC would take it to an energy of 28 TeV, not 20 TeV. And the News Feature ‘Digital DNA’ (Nature 537, 22–24; 2016) gave an incorrect size for the 2013 EBI files. The correct figure is 739 kilobytes, not 739 kilobases.
