An analysis of the bones and teeth of ancient mammoths (Mammuthus) has identified some of the microorganisms that lived in the animals’ mouths and bodies more than one million years ago. The study, ...

Bacteria are constantly moving with the help of motility organs called flagella or pili to colonize new niches. Also, bacteria can exchange information, like "speaking to each other," and thus acquire ...

Red arrows indicate the DNA repair pathways that are known to aid bacterial survival as persisters and gamblers in the presence of fluoroquinolones. Blue color arrow indicates downregulation, while ...

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...

Just like humans, mammoths had a robust community of microorganisms living on their skin and inside their bodies. Now, for the first time, scientists have identified some of the individual species ...

The bacteria that cause tuberculosis (TB) may have an "on-off switch" that lets them pause and restart growth, according to a new study from the University of Surrey and the University of Oxford. The ...
