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 ...

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 ...

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 ...

By coaxing soil bacteria into fixing more nitrogen, gene-edited wheat shows how crops might one day sidestep synthetic ...

Scientists at the University of California Davis recently developed wheat plants that stimulate the production of their own ...

The Arctic Ocean, once locked in a vault of thick, old ice, now is transforming at lightspeed. Temperatures there are increasing at up to four times the rate of the planet overall, melting sea ice ...

Scientists discovered a small protein region that determines whether plants reject or welcome nitrogen-fixing bacteria. By ...
