Antibiotics can destroy many types of bacteria, but increasingly, bacterial pathogens are gaining resistance to many commonly used types. As the threat of antibiotic resistance looms large, ...

Scientists have developed a mathematical model that predicts how the number and effects of bacterial mutations leading to drug resistance will influence the success of antibiotic treatments.

The Mfd protein repairs bacterial DNA, but can also, to scientists' surprise, promote mutation. Bacterial mutations can lead to antibiotic resistance. Understanding this second "role" of the Mfd ...

Scientists have developed a mathematical model that predicts how the number and effects of bacterial mutations leading to drug resistance will influence the success of antibiotic treatments. Their ...

Marine bacteria are key to determining whether carbon is recycled near the ocean surface or transported to deeper waters, but ...

That stickiness matters. When bacteria clump together, they sink faster, carrying carbon away from the surface ocean and into ...

Have you ever wondered whether bacteria mutate randomly or purposefully? This question has intrigued researchers for over a century. In 1943, microbiologist Salvador Luria and ...

In 1943, two scientists named Max Delbrück and Salvador Luria conducted an experiment to show that bacteria can mutate randomly, independent of external stimulus, such as an antibiotic that threatens ...
