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 ...

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

Bacteria can acquire resistance to antibiotics through random mutations in their DNA that provide them with an advantage that helps them survive. Finding genetic mutations, and discovering how they ...

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 ...

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

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 ...

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 ...

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 ...
