Mutation dynamics in bacterial populations underpin the generation of genetic diversity that drives adaptation, speciation and the emergence of antimicrobial resistance. Spontaneous base substitutions ...

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

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 ...

Deciphering the mechanisms and dynamics of bacterial evolution within a host is becoming increasingly important for understanding and thus mitigating infectious disease. The emergence of major human ...

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 ...

The retina is layered with photoreceptors, a variety of other neurons, and protective and structural membranes, but retinal disorders can tamper with this delicate system. Mutations in the Crumbs ...
