In 2015, researchers examining deep-sea sediments near the underwater volcano Loki discovered gene fragments indicating a new ...

A newly discovered parasite has caused quite a stir among microbiologists who were left scrambling to place it on the tree of life – and it seems even the organism itself is confused as to its ...

Although this helped solidify archaea’s claim, by this time most researchers had accepted that archaea, indeed, made up a third domain of life. As the DNA unraveled, archaea’s key role in Earth’s ...

In the vast and often unseen world of microscopic life, a recent discovery may force scientists to rethink what it means to ...

Archaea and eukaryotes shared a common ancestor with each other more recently than they do with bacteria, so they’re each other’s closest relatives at the domain level. Which means that ...

Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like ‘Sukunaarchaeum ...

It has genes for ribosomes, tRNAs, and mRNAs. These components are the scaffolding of life: the tools by which cells read ...

The division of all living organisms into the three domains of bacteria, archaea and eukaryotes did not hold up to this surprising discovery. Some researchers have since proposed regarding eukaryotes ...

The archaea were described in 1977 by Carl Woese and George E. Fox. They insisted that these organisms consituted a third domain of life, in addition to bacteria and eukaryotes, creating a ...

Carotenoid-producing haloarchaea impart a red color to salt ponds in San Francisco Bay. WIKIMEDIA, GROMBO While mutation and sexual reproduction drive genetic innovation in many eukaryotes, for life’s ...

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 ...

The single-cell organism grows branching appendages and contains eukaryote-like genes, though it belongs to the domain Archaea. “This is a monumental paper that reflects a tremendous amount of work ...
