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 ...

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 ...

Earth’s immense web of life fill three broad domains—archaea, bacteria, and eukarya. Scientists from Monash University recently discovered hydrogen-producing enzymes in archaea, which were thought to ...

Two pioneers of twentieth century biology passed away during the past decade, Wolfram Zillig in April 2005 and Carl Woese in December 2012. Among several other accomplishments, Woese has been ...

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 ...

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 ...

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 ...

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 ...

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, ...
