The patient in Louisiana who was hospitalized with severe bird flu illness was found to have a mutated version of the virus, the U.S. Centers for Disease Control and Prevention (CDC) announced last ...

With a rate of mutation 35 percent higher than random chance, this previously unknown weakness could be a major vector for inherited disease.

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 ...

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 ...

A new study has raised alarm bells about the potential for the H5N1 bird flu virus to evolve into a strain sparking a human pandemic. A single mutation in the virus currently ravaging dairy farms ...

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 ...

A vanishingly rare genetic glitch in a single enzyme can erase a newborn’s brain cells in a matter of weeks, leaving doctors ...

A new study by biologists from the Scripps Research Institute shows that a bird flu virus is just a single mutation away from having human-ready receptors. If the H5N1 virus does make the switch, it ...

Good morning, and welcome to the Essential California newsletter. I hope you’re enjoying your Saturday. I know my husband is — he’s currently putting holiday outfits on our two dogs, Princess Leia and ...

The avian flu virus isolated from a hospitalized teenager in Vancouver has mutations in key areas that could help the virus spread more easily in humans, scientists say. There is no indication that ...
