The biodiversity of the Earth never ceases to astonish. One example that has radically changed the face of biology is the discovery of a group of organisms called archaea (pronounced “ar-kee-ah”). It ...

An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how ...

Scientists have documented for the first time that animals can and do consume Archaea – a type of single-celled microorganism thought to be among the most abundant life forms on Earth. Archaea that ...

Microbiology has always been about recognizing the scale of what is unknown. In the beginning, the unknown was that microbes existed at all. The invention of the microscope proved that these tiny, ...

Scientists have found further evidence to support the idea that the primary two domains of life, the Archaea and Bacteria, are separated by a long phylogenetic tree branch and therefore distantly ...

Just call them archaea (ar-kee-uh) - archaebacteria are no more. Archaea were once considered to be quite similar to bacteria, but these prokaryotes are just weird enough to be classified in their own ...

Archaea are usually minor components of a microbial community and dominated by a large and diverse bacterial population. In contrast, the SM1 Euryarchaeon dominates a sulfidic aquifer by forming ...

Since the formal recognition of the archaeal domain around two decades ago (Woese et al., 1990), knowledge of the biology, diversity and ecology of this microbial group has grown considerably. Archaea ...

A parasite that not only feeds off 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 ...

In an article published in the journal Emerging Infectious Diseases, the authors discussed the involvement of archaea, a lesser-known but important component of the human microbiome, in various ...

Thanks to microscopy, early biologists were able to make a binary distinction: there were eukaryotes and bacteria. The former had large, complex cells with internal compartments, while the latter were ...

CORVALLIS, Ore. – A team of scientists has documented for the first time that animals can and do consume Archaea – a type of single-celled microorganism thought to be among the most abundant life ...
