Originally discovered in extreme environments such as hydrothermal vents, archaea, a single-celled microorganism, can also be found in the digestive systems of animals, including humans in which they ...

In a paper published in Science Advances, the Pilhofer Lab (IMBB) together with the Albers Lab from the University of Freiburg describe the structure and function of contractile injection systems from ...

Archaea come in various shapes, from cocci to filaments. However, unlike the cell shape determinants in bacteria, the factors that are important in cell shape determination in archaea are not well ...

A comparison of immune proteins called viperins from Asgard archaea (left) and from a group of more complex life that includes humans, called eukaryotes (right). The three-dimensional shapes (a.k.a.

When you get infected with a virus, some of the first weapons your body deploys to fight it were passed down to us from our microbial ancestors billions of years ago. According to new research from ...

Compressing a type of single-celled microorganism makes it develop into a multicellular tissue-like structure with different cell types. This suggests that pressure can help drive key evolutionary ...

It turns out your skin is crawling with single-celled microorganisms -- and they're not just bacteria. A study has found that the skin microbiome also contains archaea, a type of extreme-loving ...
