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 ...

For decades, the standard explanation for autoimmune diseases like rheumatoid arthritis has rested on two pillars: inherited ...

What causes autoimmune disease? A new study finds that somatic mutations in immune checkpoint genes like PDL1 trigger the ...

The study of experimental evolution in Escherichia coli has provided unprecedented insights into the mechanisms of adaptive mutations, elucidating how populations diverge and optimise their fitness ...

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 ...

Researchers published a new study, “Ongoing chromothripsis underpins osteosarcoma genome complexity and clonal evolution,” in Cell that they say solves the mystery of what drives the genomic ...

A surprising discovery from high-altitude animals like yaks and Tibetan antelopes could reshape how we treat nerve damage in humans. Scientists found that a genetic mutation helping these animals ...

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 ...

Vaccinating birds against bird flu reduces the spread of the disease, but may have unintended consequences. This is the warning of a new paper in the journal Science Advances, which concluded that ...

More than two years after H5N1 bird flu was first detected in U.S. dairy cattle, the virus has proven remarkably good at ...
