The circadian rhythm is the body's clock, and it influences physiology at the cellular level; it can help animals, including humans, know when it's time to eat, wake up or go to sleep. Recent work has ...

Here we show that DNA polymerases derived from the bacterium E. coli are considerably more prone to errors under microgravity, such as occurs in space. Our results thus have important implications for ...

Researchers have demonstrated how bacteria coordinate cell division with the replication of their genetic material. In an interdisciplinary study they explain why the current concept of the bacterial ...

Plasmids, small circular DNA molecules found in bacteria, may contain antibiotic-resistance genes and have the ability to replicate independently. Bacteria can transfer these plasmids to one another, ...

Researchers from Durham University, Jagiellonian University (Poland) and the John Innes Centre have achieved a breakthrough in understanding DNA gyrase, a vital bacterial enzyme and key antibiotic ...

The bacteria that cause tuberculosis (TB) may have an 'on-off switch' that lets them pause and restart growth, according to a new study. The research helps explain why TB is so hard to treat with ...

Colibactin is a powerful toxin produced by Escherichia coli and other bacteria living in the human gut. This highly unstable bacterial product causes mutations in DNA that have been linked to ...
