As bacteria become increasingly resistant to antibiotics and other antibacterials, there is a growing need for alternatives. In a study published in the open-access journal PLOS Biology, Tobias ...

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, ...

It turns out your skin is crawling with single-celled microorganisms – ­and they’re not just bacteria. A study by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and ...

Share on Pinterest New research sheds light on archaea — an important part of the human microbiome. Victor Torres/Stocksy The human microbiome includes bacteria, viruses, fungi, and archaea. Most ...

Just call them archaea (ar-kee-uh) - archaebacteria are no more. Archaea were once considered to be quite similar to bacteria, but these prokaryotes are just weird enough to be classified in their own ...

Asgard archaea, our closest known microbial relatives, play a key role in current models of the origin of more complex ...

In 1977, Woese and Fox proposed the Archaea as a new domain of life and that the tree of life is divided into three branches — the Eukarya, Bacteria and Archaea. Although a three-domain tree was ...

Scientists know relatively little about archaea compared to their bacterial counterparts, but evidence of their roles in health and disease are beginning to trickle in. Methanogens are not the only ...

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that’s added to a chain of amino acids ...

Thanks to microscopy, early biologists were able to make a binary distinction: there were eukaryotes and bacteria. The former had large, complex cells with internal compartments, while the latter were ...
