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, ...

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 ...

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 ...

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 ...

Researchers report that phage resistance in ocean bacteria can alter growth, metabolism and sinking behavior, revealing a ...

Bacteria inside cancerous tumors may be a key reason why immunotherapy works for some patients but not others, researchers from the Cleveland Clinic and other institutes have discovered. Two new ...

Cleveland Clinic researchers have discovered that bacteria inside cancerous tumors may be key to understanding why ...

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 ...

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 ...

Disinfectants such as bleach, acids, phenols, and alcohols are important weapons against infectious diseases. During the COVID-19 pandemic, as the coronavirus ran rampant across the world, experts ...
