Bacteria forge nitrogen from nitric oxide: Scientists unravel key pathway in the nitrogen cycle
The anaerobic oxidation of ammonia (anammox) is an important pathway in the nitrogen cycle that was only discovered in the 1980s. Currently, scientists estimate that about 50 percent of the nitrogen in the atmosphere is forged ...

Earth is having a bad acid trip, study finds
Earth may be overdosing on acid - not the "turn on, tune in, drop out" kind, but the "kill fish, kill coral, kill crops" kind. And it's shaping up to be a very bad trip.

Nitrogen oxide
The term nitrogen oxide typically refers to any binary compound of oxygen and nitrogen, or to a mixture of such compounds:
(Note that the last three are unstable.)
Chemical reactions that produce nitrogen oxides often produce several different compounds, the proportions of which depend on the specific reaction and conditions. For this reason, secondary[clarification needed] production of N2O is undesirable, as NO and NO2 — which are extremely toxic — are liable to be produced as well.
