For a long time, evolutionary biologists have thought that the genetic mutations that drive the evolution of genes and proteins are largely neutral: they're neither good nor bad, but just ordinary ...

In adults, damage to myelin is a hallmark of MS. In this condition, the immune system mistakenly attacks and destroys the ...

The number of known proteins is infinitely small in comparison to the universe of possible proteins, which could in theory be ...

Scientists from the Broad Institute of MIT and Harvard in Cambridge, Massachusetts, have identified novel mutations in bacteria that promote the evolution of high-level antibiotic resistance. The ...

A major evolutionary theory says most genetic changes don’t really matter, but new evidence suggests that’s not true. Researchers found that helpful mutations happen surprisingly often. The twist is ...

Rachel Robson, assistant professor of biology at Morningside College, and Susan Burns, associate dean for academic affairs, collaborated on an article that was published in the May issue of the ...

Groundbreaking research shows that as men age, harmful genetic mutations in sperm become more common—not just from random chance, but because some are naturally favored. Advanced sequencing revealed ...

Many people hold the view that evolution in humans has come to a halt. But while modern medicine and technologies have changed the environment in which evolution operates, many scientists are in ...

A SARS-CoV-2 subvariant called BA.3.2, carrying a significant genomic deletion and mutations linked to immune evasion, has been detected among travelers arriving in the United States. The variant, ...
