Plants need nitrogen to grow. Many legumes meet this need through a symbiotic relationship: They harbor bacteria that fix ...

Securing sustainable food supplies is a key challenge for long-term human exploration and potential habitation of the moon.

The shrinking sea ice in the Arctic Ocean is, overall, a disaster. But paradoxically, the melting of the ice can also fuel the engine of the Arctic food chains: algae. Algae are the main food source ...

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 ...

A new research initiative led by associate professor of bacteriology Betül Kaçar is positioned to transform agriculture and address some of the world’s most pressing ecological and economic challenges ...

Biological nitrogen fixation (BNF) underpins the fertility and resilience of tropical forests by converting atmospheric N₂ into plant-available forms. In these ecosystems, both symbiotic associations ...

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 ...

A new study reveals a wavelength-dependent photo-driven pathway for ammonia synthesis over lithium hydride (LiH), offering a way to decouple two ...

Marine nitrogen fixation, the conversion of inert dinitrogen gas into bioavailable nitrogen compounds by specialised microorganisms, underpins the productivity of the world’s oceans. Diazotrophic ...

Crop yields have increased substantially over the past decades, occurring alongside the increasing use of nitrogen fertilizer. While nitrogen fertilizer benefits crop growth, it has negative effects ...

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 ...

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 ...
