The structure of how DNA is stored in archaea makes a significant difference to how quickly it evolves, according to a new study by Indiana University researchers. The study, led by molecular ...

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 ...

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 ...

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 ...

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 ...

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 ...

Share on Pinterest New research sheds light on archaea — an important part of the human microbiome. Victor Torres/Stocksy The human microbiome includes bacteria, viruses, fungi, and archaea. Most ...

Living in the Dead Sea would be a very unpleasant experience for most creatures. With salt concentration above 30% and temperatures ranging from 10–50°C, it takes unique environmental adaptations to ...

Life is not possible without nitrogen. There are many ways for organisms to acquire nitrogen. For example, humans eat proteins for their high nitrogen content. Most microorganisms take up nitrogen ...

Archaea are often mistaken as bacteria, given that both are small, single-cell organisms. However, archaea are as genetically different from bacteria as humans are from bacteria. While archaea are ...
