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

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments ...

For example ... the genomes of many bacteria and some archaea (Raoult & Forterre 2008). Viruses typically lack many of the genes that are universal among the three domains of cellular life ...

Asgard archaea may have led to the evolution of eukaryotic life ETH Zurich researchers identify actin and microtubule ...

Like bacteria, archaea are single-celled organisms. Genetically, however, there are significant differences between the two domains, especially regarding their cell envelopes and metabolic processes.

as well as in a few bacteria and archaea species, the new study establishes divergent transcription—the reading of genes in both directions—as a widespread feature conserved across all three domains ...

perhaps shortly after the divergence of the domains Bacteria, Archaea and eukaryotes. As bacterial species were evolving, they could have shared genes with early eukaryotes either directly or ...
