Tiny relatives of our cellular ancestors reshape long protrusions within minutes and pull themselves across surfaces using ancient actin machinery.

Asgard archaea, our closest known microbial relatives, play a key role in current models of the origin of more complex ...

Archaea are organisms consisting of a single cell without a nucleus and with distinct structural, physiological and evolutionary characteristics. They inhabit a wide range of habitats, including ...

Asgard archaea, our closest known microbial relatives, play a key role in current models of the origin of more complex ...

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 ...

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that’s added to a chain of amino acids ...

In the late 1970’s, our understanding of the tree of life was fundamentally changed with the discovery and recognition of Archaea, a third domain of life along with Bacteria and Eukarya. While ...

A schematic tree of life with the primary domains, the Archaea and Bacteria shown in purple and blue, respectively and the secondary domain, Eukaryotes in green. The figure highlights key nodes in the ...

Scientists describe a previously unknown phylum of aquatic Archaea that are likely dependent on partner organisms for growth while potentially being able to conserve some energy by fermentation. In a ...

Antarctic dwelling single-celled microorganisms called archaea can behave like parasites, new research shows. In Antarctica is a small lake, called Deep Lake, that is so salty it remains ice-free all ...
