Ammonia-oxidizing archaea (AOA) are some of the most abundant microorganisms in the ocean and play a key role in nitrogen cycling. Yet, despite their ubiquity, scientists have long puzzled over how ...

Antarctic dwelling single-celled microorganisms called archaea can behave like parasites, new research shows. In Antarctica is a small lake, called Deep Lake, that is so salty it remains ice-free all ...

Uptake of ammonium ions by marine microorganisms called archaea is a key first step in the conversion of ammonium to nitrogen found in ecosystems. Structural evidence reveals how archaea capture ...

A first look into the molecular defenses of archaea highlights the importance of surveying diverse microbes to discover new types of antimicrobials As bacteria become increasingly resistant to ...

Archaea are a relatively recently discovered group of microorganisms that occupy their own branch on the tree of life. Though similar in some ways to bacteria, they are not the same. Researchers have ...

Scientists from the Swiss Federal Institute of Technology Zurich (ETH Zurich) revealed key details about the evolution of life on Earth by studying microorganisms known as Asgard archaea. The study ...

Microbial communities are especially active near hydrothermal seeps like those in the Guaymas Basin in the Gulf of California. The team of researchers has been working on understanding these ...

The microorganisms on Earth have managed to find a home nearly everywhere, even in what seems like the most inhospitable of places. There is a lake in Antarctica with levels of salt that are so high, ...
