Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like ‘Sukunaarchaeum ...

Two life forms living together helped spark the evolution of all complex life. By learning to appreciate this process more ...

Over time, the nucleus and other compartments evolved, and the eukaryotic cell was born. There is growing evidence that eukaryotes may have evolved from Asgard archaea.

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.

Evo is a large language model that is not trained on words but on the genomes of millions of microbes. It can accurately ...

Every living organism falls into one of two groups: eukaryotes or prokaryotes, with cellular structure determining which group an organism belongs to. Prokaryotes are unicellular and lack a nucleus ...

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 ...

The much older prokaryotic cells, which make up the vast kingdoms of bacteria and archaea and whose cells lack these features, never got complex multicellularity off the ground. They have evolved ...

Co-first authors of the Cell study, “Extracellular cytochrome nanowires appear to be ubiquitous in prokaryotes,” are Diana P. Baquero and Virginija Cvirkaite-Krupovi, Institut Pasteur.

Now Fengbin “Jerry” Wang, Ph.D., of the University of Alabama at Birmingham and colleagues in Paris and Virginia report that such nanowires, composed of a long chain of cytochrome proteins, appear to ...

About 50 years ago, a subset of unicellular organisms, the Archaea, were shown to have a different line of descent as compared to bacteria. The two differ in the composition of their cell walls ...
