Solved: Mystery of marine nitrogen cycling in shelf waters

Nitrogen cycling in shelf waters is crucial to reduce surplus nutrients, which rivers pour out into the ocean. Yet this process is poorly understood. Scientists from Bremen have now found answers to a longstanding mystery ...

Understanding microbial competition for nitrogen

Nitrogen is a hot commodity in the surface ocean. Primary producers including phytoplankton and other microorganisms consume and transform it into organic molecules to build biomass, while others transform inorganic forms ...

Nitrite's significant role in nitrous oxide emissions from soil

Nitrous oxide can contribute significantly to atmospheric warming because, pound for pound, this greenhouse gas absorbs 300 times more radiation than carbon dioxide. It is also the most important stratospheric-ozone-depleting ...

Multi-heterointerfaces for selective and efficient urea production

A major impediment to industrial urea synthesis is the lack of catalysts with high selectivity and activity. Prof. Yuliang Li (Institute of Chemistry, Chinese Academy of Sciences) and coworkers reported a new catalyst system ...

Researchers report nitrate respiration of an enteropathogen

The human pathogen Vibrio cholerae has stumped scientists since its discovery 150 years ago. Experts who studied the bacterium were puzzled that the bacterium was unable to grow under anaerobic conditions although it was ...
