The marine nitrogen cycle is crucial to sustaining ocean productivity, with biological nitrogen fixation representing a primary mechanism by which inert atmospheric nitrogen is converted into ...

Nitrogen is vital for all known life. Yet most nitrogen on Earth is in the atmosphere as di-nitrogen gas, which many organisms can’t use. Fortunately, there are microbes that can tap into this ...

Nitrogen, upon which all life on Earth depends, may hold the key for explaining how early life on the planet evolved and how it could evolve on other planets.

A new study examined nitrogen fixation among diazotrophs--microorganisms that can convert nitrogen into usable form for other plants and animals -- living among sargassum. Sargassum, a brown ...

As the Arctic Ocean loses its sea ice due to climate change, sunlight penetrates deeper into the water and encourages the growth of tiny plant-like organisms (phytoplankton). But to thrive, they need ...

A research team has discovered how the 'Shethna protein II' protects the nitrogen-fixing enzyme nitrogenase from damage. The oxygen sensor protein could help to make nitrogenase usable in ...

Most organisms require nitrogen to produce biological molecules, such as nucleotides and amino acids, but until recently, only prokaryotes were known to fix nitrogen from the atmosphere. “It’s a very ...

Custom Chemistry has managed to acquire 3% of the South African agricultural nitrogen fertiliser market in the past three ...

Global inventory reveals nitrogen is in shorter supply than previously thought in natural areas, which could limit carbon storage in plants and soils. “Outside of some tropical forests and drylands, ...

Nitrogen shortage limits young tropical forest growth, slowing carbon capture that could help fight climate change.
