Genetic data reveal a group of bacteria that are so diverse genetically that they represent half of all the diversity of bacteria on the planet New research suggests that the Tree of Life is vastly ...

Defense systems found in all complex life on Earth came from "Asgard." The ancestor of plants, animals and fungi evolved around 2 billion years ago, likely from a group of complex microbes called ...

An international scientific team has redefined our understanding of archaea, a microbial ancestor to humans from two billion years ago, by showing how they use hydrogen gas. The findings explain how ...

In many submerged regions, murky mud shelters strange life-forms that seem to be the key to one of the biggest mysteries of life on Earth. These creatures belong to a domain of life called the archaea ...

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 ...

Our hands are mirror images of each other. Unless you flip one hand around, they’ll never look the same. Scientists call this chirality, and the mirror-like property is fundamental to all life on ...

A new version of Evo, the AI developed at the Arc Institute that can be used to design genomes as long as that of a bacterium, has been retrained with the DNA sequences of three domains of life – ...

In the mid-1990s, scientists made a discovery that shook up the understanding of life on Earth: vast reservoirs of microbes can be found beneath the planet’s surface, often buried kilometers deep in ...
