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 fixation is surprisingly high in the ocean's coastal waters and may play a larger role than expected in carbon dioxide uptake, a new study shows. The findings -- based on thousands of samples ...

I was taken back a significant period of years by the article in C&EN on nitrogen fixation as a potential answer to the massive overuse of fertilizers (July 31, 2023, page 24). The underlying reasons ...

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 ...

The top row of images are CARD-FISH images of UCYN-A haptophyte symbiosis in the Bering Sea. The nitrogen fixing cyanobacteria UCYN-A2 are shown in red and the Haptophyte algae host are shown in blue ...

Scientists have developed a uranium-based complex that allows nitrogen fixation reactions to take place in ambient conditions. The work lays the foundation to develop new processes for synthesizing ...

High levels of atmospheric carbon dioxide intensify climate change, but high carbon dioxide levels can also stimulate plant growth. Plant growth removes carbon dioxide from the atmosphere, partially ...

A new evaluation of biological nitrogen fixation for inland and coastal waters concludes that these habitats are an overlooked but important source of fixation globally. Robinson Fulweiler and ...

Forests, grasslands, and other natural areas around the world have access to about a quarter less nitrogen than previously estimated, according to a new study published in Nature. Coauthored by Sarah ...
