An international team led by Monash University researchers has uncovered the genetic code governing the way genetic mutations ...

Thousands of previously “invisible” microproteins—tiny chains of fewer than 100 amino acids—can profoundly change human biology when mutated. A fundamental discovery is overturning decades of ...

A newly discovered genetic mutation unique to humans may help explain why we are significantly more vulnerable to cancer than our closest evolutionary relatives. Researchers at the University of ...

Unique mutations in the H5N1 strain enhance replication in human cells and cause severe disease in mice. The virus has spread from birds to mammals, including dairy cows, and infected humans, with one ...

Our brains evolved for complex thought and language - but the same genes that made us smarter may have increased mental illness risk.

In a study published in Neuron, a research team at the Department of Neurology at Massachusetts General Hospital, aimed to ...

Helen Branswell covers issues broadly related to infectious diseases, including outbreaks, preparedness, research, and vaccine development. Follow her on Mastodon and Bluesky. You can reach Helen on ...

Human eggs appear to be protected against a certain type of age-related mutation. In a small study, researchers found no signs that mutations accumulate in the mitochondrial DNA of human egg cells as ...

At least 58 people in the U.S. have been infected by the H5N1 bird flu virus this year, according to federal statistics. All but two of them had been around cows or chickens, two species in which H5N1 ...
