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 ...

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 ...

CO2 can stimulate plant growth, but only when enough nitrogen is available—and that key ingredient has been seriously ...

Considered natural allies against climate change due to their absorption of carbon dioxide, plants may however offer more ...
