Scientists trace an ancient microbe, Asgard archaea, that gave rise to humans, animals, and plants more than 2 billion years ...

A genetic analysis of soil samples indicates that a group of microorganisms called crenarchaeota are the Earth’s most abundant land-based creatures that oxidize ammonia, according to an international ...

Jump into 2026 with a recap of UCSB's most recent research innovations.

Researchers discover a unique genetic code in Antarctic archaea that encodes a rare amino acid, potentially advancing protein ...

A newly discovered promoter element "start" points to a shared regulatory syntax for controlling transcription initiation in bacteria, archaea, and eukaryotes.

Earth’s first life forms eventually took one of three different paths, forming the domains of Eukarya, Bacteria, and Archaea. These domains have been evolving separately for billions of years. Recent ...

Following the drive to understand and control bacteria, it’s becoming clear that our methods have changed the very organisms we aim to understand, increasing resistance to tried-and-true antimicrobial ...

AIST researchers, in collaboration with JAMSTEC, Hokkaido University and Tohoku University, have succeeded in cultivating an ultrasmall bacterial strain parasitizing archaea and classified the strain ...

A parasite that not only feeds of its host, but also makes the host change its own metabolism and thus biology. NIOZ microbiologists Su Ding and Joshua Hamm, Nicole Bale, Jaap Damsté and Anja Spang ...

Let’s say you’ve discovered a new bacterium or archaea and want to give it a name so that it can be classified and placed on the appropriate branch of the tree of life. According to the International ...
