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 ...

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 ...

Scientists have pinpointed precise regions in the human genome where DNA is most likely to develop a mutation. At spots where RNA polymerase 'opens' your DNA to read and copy instructions – known as ...

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 ...

Scientists have revealed parts of the genome that are especially vulnerable to mutations that occur very early on in development. These areas are in the initial portions of genes, where the cell tends ...

Concern surrounding the highly pathogenic avian influenza H5N1 influenza virus currently circulating in dairy cows in the United States is growing. A total of 58 human cases have been reported as of ...

Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we ...
