The News story 'Where the US stimulus money is going' ( Nature 461, 856–857; 2009) gave the wrong location for the National Synchrotron Light Source II. It is at the Brookhaven National Laboratory in New York. And in the News Feature 'The disappearing nutrient' ( Nature 461, 716–718; 2009), the estimate for the amount of phosphate that could be extracted from the ground should have been 47 billion tonnes not 62 billion. This means that the figures in the pie chart should have read: United States (3.4 Gt), China (10 Gt), Morocco and Western Sahara (21 Gt), South Africa (2.5 Gt) and Rest of the world (10.1 Gt).
