The graph of a hypothetical stock portfolio in the News story 'Blockbuster drug bows out' (Nature 480, 16–17; 2011) omitted the effects of dividends and stock splits; instead of losing 39%, it should have risen by 82%. Similarly, US$100 worth of Pfizer stock in 1986 would have grown to $2,139 by 1999 and shrunk to $1,629 by the end of 2010.

The News Feature 'Master of illusion' (Nature 480, 168–170; 2011) wrongly attributed the idea “if there's something you can be certain of in this world, it's that your hand is your hand” to Descartes instead of G. E. Moore.
