The graphic in the News story ‘Pluto mission hunts for hazards’ (Nature 521, 14–15; 2015) put Nix on the wrong orbital path. The correct image can be seen at go.nature.com/sbpxsu. The News story ‘Pint-sized DNA sequencer impresses first users’ (Nature 521, 15–16; 2015) mistakenly stated that the MinION device has problems reading long, repetitive regions of DNA sequence. It should have said that those difficulties occur in sections of genome that are rich in long stretches of a single DNA base. And the reference list in the News story ‘Mysterious galactic signal points LHC to dark matter (Nature 521, 17–18; 2015) omitted two entries. The complete list can be seen at go.nature.com/mzopta.
