Scientists have discovered a way to control mutation rates in bacteria, paving the way for new strategies to combat antibiotic resistance. Antibiotics are given to kill bad bacteria; however, with ...
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 ...
Mutation dynamics in bacterial populations underpin the generation of genetic diversity that drives adaptation, speciation and the emergence of antimicrobial resistance. Spontaneous base substitutions ...
For about 40% of people diagnosed with colorectal cancer (CRC), the tumor carries a mutation in a gene called KRAS. Many of those mutations have been linked to shorter survival and more aggressive ...
A Monash University-led study has found that an unusual pairing of two commonly used antibiotics can kill and stop the spread ...
As bacteria become increasingly (and worryingly) resistant to antibiotics, scientists are recruiting bacteriophages—a bacteria’s sworn evolutionary enemy—to fight against these troublesome “superbugs.
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 ...
Add Yahoo as a preferred source to see more of our stories on Google. Increased consumption of ultraprocessed foods can impact children’s gut health and immunity, leaving them more susceptible to the ...
Researchers have described how the bacterium Staphylococcus aureus genetically adapts to humans, including mutations that allow some strains to evade the immune system and become resistant to ...
About six years ago, Srivatsan Raman, a biochemist at the University of Wisconsin-Madison, and his team took a trip to NASA’s Wallops Flight Facility in Virginia. Standing a mile away from the ...
Colon cancer is a particularly deadly form of cancer, and the incidence of the disease is rising, especially among younger people. Research has suggested that the composition of the gut microbiome, or ...
