Scientists have traced a devastating pattern of brain cell loss in a handful of families to a single, ultra-rare mutation ...

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

Experiments on an ultra-rare genetic mutation that causes neurodegeneration in children have helped uncover a new mechanism by which brain cells die. The findings raise the possibility that similar ...

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 ...

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 ...

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 ...

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 ...

Most mutations that cause disease by swapping one amino acid out for another do so by making the protein less stable, according to a major study of human protein variants that was published in Nature ...

A team of researchers at the Icahn School of Medicine at Mount Sinai has uncovered why children with the same leukemia-causing gene mutation can have dramatically different outcomes: It depends on ...

It's not just the number of mutations that matters. It's the failure to fix them too. The male reproductive system serves as a hotspot for the emergence of new genes. Perhaps that explains why more ...
