A study published in PLOS PATHOGENS describes the prevalence and functions of mutations in neuraminidase enzyme of avian H5N1 influenza viruses that are preferentially selected in human H5N1 influenza ...

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 ...

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

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 ...

Are we evolving to be more stupid? Humans have a relatively high genetic mutation rate, which has been thought to be driving ...

Two critical mutations appeared roughly 200,000 years ago in a gene linked to language, then swept through the population at roughly the same time anatomically modern humans began to dominate the ...

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 ...

The human genome is contained in the nucleus of almost every cell in the body. But those cells also contain multitudes of mitochondria, and these incredible little power-generating organelles carry ...

Colorized scanning electron micrograph of an apoptotic cell (pink) heavily infected with SARS-CoV-2 virus particles (green), ...
