The most widely accepted scientific explanation for the arrival of all complex life on Earth has had an unsolved mystery at its heart. According to the theory, all plants, animals and fungi, known ...
Complex cells are thought to be the result of a union between two ancient microorganisms, but scientists have long been ...
New genomic research shows some Asgard archaea, ancestors of plants, animals, and fungi, tolerated and used oxygen. The finding supports the idea that complex life arose after oxygen levels surged and ...
Archaea are a relatively recently discovered group of microorganisms that occupy their own branch on the tree of life. Though similar in some ways to bacteria, they are not the same. Researchers have ...
An artist’s depiction of an Asgard archaeon, based on cryo-electron tomography data: the cell body and appendages feature thread-like skeletal structures, similar to those found in complex cells with ...
Archaea are microorganisms that were only discovered in the 1970s, and scientists still have a lot to learn about them. One challenge is that archaea are difficult to raise in the laboratory. As of ...
John M. Archibald is in the Department of Biochemistry and Molecular Biology, Dalhousie University, Halifax, Nova Scotia B3H 4H7, Canada, and also at the Institute for Comparative Genomics, Dalhousie ...
An international team of microbiologists from the Medical University of Graz, the DSMZ—German Collection of Microorganisms and Cell Cultures (Braunschweig, Germany)—and the University of Illinois (U.S ...
Current hypotheses suggest that all life on Earth evolved from a common ancestor that diversified into the variety of organisms seen today. Scientists propose that the eukaryotic branch of this family ...
Life is not possible without nitrogen. There are many ways for organisms to acquire nitrogen. For example, humans eat proteins for their high nitrogen content. Most microorganisms take up nitrogen ...
