Mutations are fundamental to evolutionary change, driving the emergence of new traits, species, and, in some cases, resistance to antibiotics. This study provides strong evidence that transcriptional ...

Scientists studying how microbes evolve have long assumed that nearly all new genetic mutations get passed down at a predictable pace and usually without either helping or hurting the microbe in ...

Do bacteria mutate randomly, or do they mutate for a purpose? Researchers have been puzzling over this conundrum for over a century. In 1943, microbiologist Salvador Luria and physicist turned ...

Scientists have shown in laboratory experiments that an increase in temperature from 37 to 40 degrees Celsius increased the resistance rate for two antimicrobials, while for a third antimicrobial, the ...

Everyday non-antibiotic meds like ibuprofen and paracetamol can make E. coli more likely to mutate and resist antibiotics. The study looked at how nine widely used medications interact with the ...

As antibiotic resistance continues to rise worldwide, scientists are searching for new strategies to combat infections. This ...

Traditional biochemical methods of studying human gene mutations are often laborious and costly. Now bioengineers at the University of California San Diego have developed a new simple approach to ...

Marine bacteria are key to determining whether carbon is recycled near the ocean surface or transported to deeper waters, but many operate in constant threat of being infected by viruses called phages ...

Bacteriophage T7, a virus that preys on E. coli, becomes a more effective killer after spending time aboard the International ...
