The understanding of ocean mechanisms in the Arctic is currently experiencing a real turning point. Research conducted by the ...

The discovery of non-cyanobacteria diazotrophs underneath Arctic sea ice could change our understanding of the food web, as well as the ocean's carbon budget.

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 ...

As the Arctic Ocean loses its sea ice due to climate change, sunlight penetrates deeper into the water and encourages the ...

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 ...

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 ...

It has puzzled scientists for years whether and how bacteria, that live from dissolved organic matter in marine waters, can carry out N 2 fixation. It was assumed that the high levels of oxygen ...

Nitrogen fixation was measured in the water column of Lake Mize, Florida, a highly colored, small, deep lake, and in a variety of lacustrine sediments, by the acetylene reduction technique. A ...

Ever wanted to produce nitrogen fertilizer like they did in the 1900s? In that case, you’re probably looking at the Birkeland-Eyde process, which was the first industrial-scale atmospheric nitrogen ...

Scientists have been left baffled after finding 'impossible' life thriving at the north pole. The tiny microorganisms, invisible to the naked eye, live just beneath the frozen surface of the central ...
