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

especially regarding their cell envelopes and metabolic processes. After a further search, microbiologists identified the ...

Archaea are organisms consisting of a single cell without a nucleus and with distinct structural, physiological and evolutionary characteristics. They inhabit a wide range of habitats, including ...

Scientists propose that the eukaryotic branch of this family tree formed when two prokaryotes, an ancient bacterium and archaeal cell, merged, forming a symbiotic relationship maintained over time. 1 ...

Researchers have used two primary methods to assess cell morphology: microscopy and flow cytometry. Microscopic examination mostly relies on image interpretation, where the human eye analyzes cell ...

Adapted from Spang and Ettema, 2016. The billions of years separating Bacteria and Eukaryotes qualify archaeal cell biology as one of the most promising fields for unseen biological phenomena. In our ...

Genetically, however, there are significant differences between the two domains, especially regarding their cell envelopes and ... classified them as a separate archaeal sub-group: Asgard archaea.
