The finding of the amoA gene in archaea populations has raised the prospect of an important role for ammonia-oxidizing archaea (AOA) in nitrification in different ecosystems 1,9. The amoA gene encodes ...

It could never be found until recently, in a fish tank a few floors below a university microbiology department: one single organism able to perform the complete process of nitrification.

But different microbes have distinct roles to play, and environmental factors influence activity. Under our feet, in the soil, is a wealth of microbial activity. Just like humans have different ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Nitrous oxide is a powerful greenhouse gas. Its global warming potential can be up to 300 times that of CO2 over a 100-year period. Globally, more than half of man-made nitrogen oxide emissions come ...
