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 ...

BETHESDA, Md. — Your body is quietly collecting genetic changes right now, and scientists want to map every single one. A massive new research network is launching the most ambitious genetic study ...

A study by IRB Barcelona reveals that transfer RNA (tRNA) genes accumulate mutations at a frequency up to nine times higher ...

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 ...

H5N1 bird flu samples collected from a severely ill patient in Louisiana show signs of mutations that may make the virus more transmissible to humans, the Centers for Disease Control and Prevention ...

The findings show how the H5N1 bird flu virus is evolving in livestock and what that may mean for human health.

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 ...

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 ...
