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 ...

Life as we know it has been classified into three domains - Archaea, Bacteria, and Eukarya. The first two domains include single-celled organisms that do not have a nucleus, and there were thought to ...

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, ...

This issue marks the 40th anniversary of the publication of the landmark article by Carl Woese and George Fox in which they proposed the Archaea as a third domain of life in addition to the Eukarya ...

In the world of microbes, as in politics, some groups just can't seem to shake the label ''extremist.'' So it is with archaea, bacteria-like microorganisms whose unique genetics and chemical structure ...

Archaea comprise the third domain of life, alongside bacteria and eukaryotes. The domain Archaea was proposed in 1977 by Carl Woese, as a result of phylogenetic studies that used ribosomal-RNA ...

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 ...

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 ...

Archaea are the third domain of life, separate from the domains of bacteria and eukaryotes. While bacteria and archaea are both unicellular organisms that lack a nucleus, they are very different in ...

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 ...

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 ...
