The biodiversity of the Earth never ceases to astonish. One example that has radically changed the face of biology is the discovery of a group of organisms called archaea (pronounced “ar-kee-ah”). It ...

To carefully determine the phylogenetic position of the novel Asgard lineages in relation to other Archaea and to eukaryotes, we performed various in-depth phylogenomic analyses of concatenated rRNA ...

Microbiology has always been about recognizing the scale of what is unknown. In the beginning, the unknown was that microbes existed at all. The invention of the microscope proved that these tiny, ...

Even hyperthermophiles, which grow optimally at temperatures of more than 80°C, require a functional heat-shock response to cope with exposure to temperatures that exceed their optimal growth ...
