To date, species of the genus Sulfolobus have served as the main model organisms for investigations of the cell cycle in archaea. Archaea have circular chromosomes with single or multiple ...

In this Analysis article, Makarova and colleagues provide an overview of the cell division and membrane budding systems of the Archaea. They show that at least four different systems regulate ...

The 12-year-long endeavor reveals Prometheoarchaeum as a tentacled cell, living in a symbiotic relationship with methane-producing microbes. Elusive Asgard Archaea Finally Cultured in Lab Elusive ...

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.

The 12-year-long endeavor reveals Prometheoarchaeum as a tentacled cell, living in a symbiotic relationship with methane-producing microbes. Elusive Asgard Archaea Finally Cultured in Lab Elusive ...

The origin of these microtubules has been unclear -- until now. In a newly published article in Cell , the ETH researchers discovered related structures in Asgard archaea and describe their structure.

Archaeal proteins that can aid in the fusion of cell membranes could offer insights into how complex life forms that undergo sexual reproduction may have evolved from simple cells, noted study ...

Asgard archaea rely on a number of genes that previously had been found only in eukaryotes. It was possible that these microbes were using these genes for the same purposes — or for something else.

Because they rely on hosts for a majority of functions, viruses aren’t considered alive. But entities like this one complicate matters.

(A) We coated the surface of glass substrate with tetraethylene glycol (TEG, brown) and the layer was partially degraded by UV irradiation to prepare hydrophilic cell adhesive surface (green ...

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

Mitosis and meiosis are two kinds of cell division that are essential to most forms of life on earth. Here we investigate the key differences and similarities between the two processes.
