On the shores of the west coast of Australia lies a window to our past: the stromatolites and microbial mats of Gathaagudu ...

At first sight, stromatolites may seem unremarkable. The stromatolite formations found in Shark Bay, Western Australia, do ...

Aussie scientists witness a biological interaction, similar to what is believed to be a precursor to the creation of complex ...

Scientists have discovered an archaea called ‘Asgard’ in the extremely high-salinity waters of Shark Bay, Australia, which ...

Stromatolites—and their close relatives, microbial mats—could be mistaken for what seems like a bunch of old dark rocks. But ...

Single-celled archaea microbes pack their DNA into flexible coils that expand and stretch much like a Slinky does. This kind of molecular gymnastics had never been seen before in other organisms and ...

Existing bacteria and archaea still our universal common ancestor’s ribosomal hibernation defense mechanism when nutrients are scarce.

Sperm and egg cells, or gametes, are unusual. Egg cells are some of the largest cell types, and sperm are some of the smallest. In humans, these haploid cells come together to form diploid cells. It's ...

Scientists have found further evidence to support the idea that the primary two domains of life, the Archaea and Bacteria, are separated by a long phylogenetic tree branch and therefore distantly ...

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 ...

Archaea are prevalent in a range of environments, from some of the most hostile like volcanoes and permafrost. However, archaea are also common in the human microbiome and as an important part of soil ...
