The News story ‘Neutrino flip wins physics prize’ (Nature 526, 175; 2015) wrongly implied that physicists knew about all three types of neutrino in the 1960s. In fact, the tau neutrino was postulated only in the 1970s. The News Feature ‘The impenetrable proof’ (Nature 526, 178–181; 2015) wrongly located the University of Antwerp in the Netherlands. It is, of course, in Belgium. In the News Feature ‘The mitochondria mystery’ (Nature 525, 444–446; 2015), the quote “The standards for a shampoo seem to be harsher” was erroneously attributed to Ted Morrow. When he said these words, he was characterizing the stance of another researcher, not expressing his own opinion, and the quote should not have been included.
