Ocean microbes can use urea when ammonium is scarce. This helps them survive in poor waters and reshapes our view of the nitrogen cycle.

It has puzzled scientists for years whether and how bacteria, that live from dissolved organic matter in marine waters, can ...

As much as a third of the nitrogen entering the world’s oceans from the atmosphere is man-made, according to new findings by an international team of scientists. This has significant implications for ...

Nitrogen is essential for all life on Earth. In the global oceans, however, this element is scarce, and nitrogen availability is therefore critical for the growth of marine life. Some bacteria found ...

Researchers have uncovered surprising evidence that the deep ocean’s carbon-fixing engine works very differently than long ...
