The News Feature ‘Scientists and the social network’ (Nature 512, 126–129; 2014) gave the wrong affiliation for Laura Warman, who is at the University of Hawaii at Hilo. And the News story ‘Health check for deep-sea mining’ (Nature 512, 122–123; 2014) gave an incorrect list of the resources found around deep-sea vents. In fact, only polymetallic sulphides are common near the vents.
