The News Feature ‘Making the links’ (Nature 488, 448–450; 2012) misspelt David Lazer’s name and wrongly located him. He is at Northeastern University in Boston.

The News Feature ‘Man of the desert’ (Nature 488, 272–274; 2012) got the details of Kröpelin’s 2005 trip wrong. The heavy gunfire heard by the team was caused by Darfur rebels killing 20 Sudanese soldiers (not the other way round).

The News Feature ‘Armed resistance’ (Nature 488, 576–579; 2012) conflated the Puebla campuses of the University of the Americas and the Monterrey Institute of Technology and Higher Education. The former was home to the first nanotechnology lab in Mexico, the latter was the first institute in Latin America to offer an undergraduate programme in the field and had a false bomb alert last August.
