Scientists are studying the vaginal microbiome in populations all around the world to see how it might differ in different ...

Viruses, then, may have existed before bacteria, archaea, or eukaryotes (Figure 4; Prangishvili et al. 2006). Most biologists now agree that the very first replicating molecules consisted of RNA ...

The majority of these viruses infect microbes, including bacteria, archaea, and microeukaryotes, all of which are vital players in the global fixation and cycling of key elements such as carbon, ...

Researchers at Rutgers University found that the viruses consisted of bacteria while others belonged to archaea - a single-cell organism similar to bacteria - which requires extreme environments ...

The viruses that infect Asgard archaea are unique from those that have been described before.

Viruses can replicate only inside a host’s cell. Hosts of viruses include animals, plants, bacteria, fungi, and archaea. Many viruses have evolved to infect multiple kinds of hosts, while some ...

(See “Discovering Archaea, 1977,” The Scientist, March 2014) Even though viruses were by that time visible using electron microscopes, they were left off the tree of life because they did ...

The genomes of giant viruses, such as the recently discovered Mimivirus that infects amoebae, are larger than the genomes of many bacteria and some archaea (Raoult & Forterre 2008). Viruses ...

Schleper's research focuses on ecology, molecular biology and evolution of archaea, virus-host interactions and the investigation of non-cultivable microorganisms using metagenomics. Disclaimer ...
