Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments discovered gene fragments that indicated a new and previously undiscovered form ...

An artist’s depiction of an Asgard archaeon, based on cryo-electron tomography data: the cell body and appendages feature thread-like skeletal structures, similar to those found in complex cells with ...

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 ...

Microbiologists Patrick Moreira and Purificación López-García, together with virologists Arturo Ludmir and Lynn Enquist, are ...

Researchers have succeeded in cultivating an ultra-small bacterial strain parasitizing archaea and classified it as new species and genus of Minisyncoccus archaeiphilus. AIST researchers, in ...

There are few hard and fast rules in the study of life, but perhaps the closest we get is the central dogma of molecular biology: DNA is transcribed to RNA, which gets translated into proteins. The ...

Current hypotheses suggest that all life on Earth evolved from a common ancestor that diversified into the variety of organisms seen today. Scientists propose that the eukaryotic branch of this family ...

From different angles, EMBL researchers are looking at archaea with the hope these understudied organisms will answer questions about evolution ...
