In adults, damage to myelin is a hallmark of MS. In this condition, the immune system mistakenly attacks and destroys the protective layer. Reduced blood flow in the brain, which becomes more common ...

A new paper in Genome Biology and Evolution, indicates that while the COVID-19 virus has developed rapidly since 2019, it has done so within limited genetic channels. These genetic limits have ...

In the intricate machinery of the inner ear, hearing begins with a protein that moves a few billionths of a meter up to 100,000 times per second. That protein, called TMC1, sits at the tips of sensory ...

Researchers at UC San Diego have found that several of the most dangerous zoonotic viruses, including SARS-CoV-2, Ebola, and ...

Scientists have identified a genetic mutation that helps protect the brain function of animals that live in high-altitude, low-oxygen environments... | Genetics And Genomics ...

Cancer’s strongest gene switches push DNA into damaging overdrive, creating repeated breaks and repairs that may fuel tumor ...

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 ...

Are we evolving to be more stupid? Humans have a relatively high genetic mutation rate, which has been thought to be driving down our physical and mental fitness – but columnist Michael Le Page finds ...

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 ...

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 ...
