Most research has focused on bacteria, while little is known about archaea. Although archaea make up just 1.2% of the gut microbiome, they may have important regulatory effects.

The Archaea was recognized as a third domain of life 40 years ago. In this Review, Emeet al. outline a brief history of the changing shape of the tree of life and examine how the recent discovery ...

Still, current data suggests gut archaea are not as varied as their bacterial neighbors. “We made a census of the diversity of methanogens in the gut, and we found around 30 species, which is not a ...

Thor. Loki. Heimdall. They're not just Norse gods or Marvel characters. They're also the names of various Asgard archaea. These microscopic organisms are found all over the world, from marine ...

Archaea, key players in the human microbiome, are linked to various diseases but their pathogenic potential remains speculative. This study highlights their role in conditions like periodontitis ...

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.

Archaea microbes might instead simply be contorting their DNA to turn genes on and off –– allowing proteins to “read” the genes when the Slinkies open, and cutting off access when they close.
