The time-development of species communities cannot be understood solely through ecological interactions or environmental ...

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 ...

Decades of reliance on the antibiotic rifampicin have fueled the rise of drug-resistant Mycobacterium tuberculosis (Mtb). But ...

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 ...

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 ...

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 ...

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 ...

Marine bacteria are key to determining whether carbon is recycled near the ocean surface or transported to deeper waters, but many operate in constant threat of being infected by viruses called phages ...
