A numerical perspective on Nature authors.

Several authors in Germany present research in Nature this week. Andreas Richter and his team, working in Bremen and Hamburg, use satellite data to measure levels of nitrogen dioxide in the lower atmosphere and report a worrying increase in nitrogen oxide emissions over industrial areas of China (see page 129).

Thomas Blankenstein and Gerald Willimsky, at the Charité in Berlin, use mice to look at cancer immunology and show how sometimes certain types of tumour can evade an immune response (see page 141).

And Svante Pääbo, based in Leipzig, is a member of the team reporting results of a genome-wide comparison of DNA similarities between humans and chimpanzees (see page 88).
