The molecular mechanism of anaerobic ammonium oxidation has been unraveled. The anaerobic oxidation of ammonia (anammox) is an important pathway in the nitrogen cycle that was only discovered in ...

The nitrogen cycle rarely features in the grim litany of things at risk from global warming. ... Of course verifying the export of nitrogen hinges on balancing that stubborn nitrogen cycle equation.

Geochemical evidence invokes anoxic deep oceans until the terminal Neoproterozoic ~0.55 Ma, despite oxygenation of Earth’s atmosphere nearly 2 Gyr earlier. Marine sediments from the intervening ...

Then, a century ago, the nitrogen cycle changed forever when Fritz Haber, a German chemist, invented an industrial process for fixing nitrogen from the atmosphere to make chemical fertiliser.
