This article focuses on a few of the most exciting, very recent developments in the nitrogen cycle, summarises the changes and points out some questions to guide future research. The main processes of interest are anaerobic ammonium oxidation (Anammox), aerobic nitrification by archaea, nitrogen fixation by unicellular marine cyanobacteria, and the issue of the balance and coupling between internal input and removal pathways.
