The nitrogen cycle is a critical component of Earth's ecosystem, playing an essential role in sustaining life. However, human activity has significantly disrupted the natural balance of the nitrogen ...

The Thaumarchaeota play a key role in the marine nitrogen cycle. They gain energy for growth by converting ammonia, which is the most reduced form of inorganic nitrogen, to a more oxidized form: ...

When snow blankets the landscape, it may seem like life slows down. But beneath the surface, an entire world of activity is ...

Nitrogen deposition refers to the processes by which nitrogen in reactive nitrogen compounds in the air is deposited onto soil and into water. The nitrogen gas (N 2) that is naturally present in the ...

A new study shows that nitrogen-feeding organisms exist all over the deep ocean, and not just in large oxygen-depleted 'dead zones,' changing the way we think about the delicate nitrogen cycle.

The horseshoe vetch (Hippocrepis comosa), a European relative of beans, is the first plant discovered to break down nitrogen-containing compounds in its tissues into a readily usable nitrate form, ...

Tackling pollution from the emission of nitrogen compounds, particularly ammonia, could reduce many of the 23.3 million years of life that were lost prematurely across the world in 2013 due to ...

The ammonia oxidizing archaea, or Thaumarchaeota, are amongst the most abundant marine microorganisms. Yet, we are still discovering which factors allow them to thrive in the ocean: A new publication ...
