In laboratory experiments, the researchers successfully engineered this change in barley and found that the mechanism worked ...

Scientists discovered a small protein region that determines whether plants reject or welcome nitrogen-fixing bacteria. By ...

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, ...

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 ...

A closeup look at colibactin’s structure reveals chemical motifs that guide its mutation-wreaking “warheads” to specific stretches of DNA.

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 ...

A 'silent' mutation in the genetic code of bacteria has been discovered by UK researchers, offering hope for future microbial treatments. The authors of new research, published in the Proceedings of ...

Colibactin is a powerful toxin produced by Escherichia coli and other bacteria living in the human gut. This highly unstable ...

Researchers have discovered that a mutation in the cellulose making machinery of E. coli bacteria allows them to cause severe disease in people -- 'good' bacteria make cellulose and 'bad' bacteria can ...

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 ...

Increased consumption of ultraprocessed foods can impact children’s gut health and immunity, leaving them more susceptible to the bacteria. As rates of colorectal cancer soar in adults younger than 50 ...
