Natural pathogenic bacteria populations can harbour mutator alleles (with high mutation rates) that may offer a selection advantage. In the March 30 Science, Giraud et al. describe a model to ...
Space-based experiments show that microgravity-induced mutations in bacteriophages may improve their ability to target ...
Scientists studying how microbes evolve have long assumed that nearly all new genetic mutations get passed down at a predictable pace and usually without either helping or hurting the microbe in ...
A team of researchers at Baylor College of Medicine is gaining ground in their search for solutions to the global problem of bacterial antibiotic resistance, which was responsible for nearly 1.3 ...
Forbes contributors publish independent expert analyses and insights. GrrlScientist writes about evolution, ecology, behavior and health. Once hailed globally as “miracle drugs”, antibiotics have ...
Far from Earth's gravitational pull, a simple viral infection took on a new evolutionary direction. A study conducted aboard the ISS found that when bacteria and ...
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 ...
As rates of colorectal cancer soar in adults younger than 50—with the American Cancer Society reporting it to be the leading cause of cancer death among such men and the second-leading among such ...
