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 ...

Some of your most important life partners are the mitochondria that power all your cells. You and these little cellular ...

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 ...

Traditional biochemical methods of studying human gene mutations are often laborious and costly. Now bioengineers at the University of California San Diego have developed a new simple approach to ...

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 single modification in the protein found on the surface of the highly pathogenic avian influenza (HPAI) H5N1 influenza virus currently circulating in U.S. dairy cows could allow for easier ...

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 ...
