The scale on the graph showing German science spending in the News story ‘Germany hits science high’ (Nature 501, 289–290; 2013) had an incorrect scale. It should have run from €0 to €15 billion not €0–1.5 billion. And the News story ‘Grass gets greener’ (Nature 501, 291; 2013) incorrectly identified the grain that produced high yields when grown in a field that previously hosted Brachiaria grasses. It was maize (corn), not wheat.
