Space-based experiments show that microgravity-induced mutations in bacteriophages may improve their ability to target ...

In the weightlessness of space, bacteria acquired mutations in genes involved in the microbe's stress response and nutrient ...

In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless "microgravity" conditions aboard the International Space Station, but the ...

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 ...

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, ...

Queensland researchers have discovered that a mutation allows some E. coli bacteria to cause severe disease in people while other bacteria are harmless, a finding that could help to combat antibiotic ...

In the 1940s, the famous Luria–Delbrück experiment showed that bacteria evolve resistance to drugs they'd never encountered thanks to a random mutational process. When you purchase through links on ...

Far from Earth's gravitational pull, a simple viral infection took on a new evolutionary direction. A study conducted aboard the ISS found that when bacteria and ...

Scientists at Duke-NUS Medical School and the National University Health System (NUHS), together with an international team ...

Duke-NUS and NUHS scientists uncover a complex web of genetic, age-related and microbial factors that increase the risk of stomach cancer.Age-related blood cell mutations may trigger early changes in ...
