"In addition, more research is also needed to assess whether these mutations in HA have had an impact on the late-wild bird lineage." H5N1 has been detected in 10,969 wild birds as of January 16 ...

Their findings, published in Nature Aging, describe a never-before-seen link between the two most accepted explanations: random genetic mutations and predictable epigenetic modifications.

Health authorities and researchers are closely examining the mutations found in the virus extracted from the 65-year-old man, who was infected through contact with backyard birds contaminated by ...

A human strain of H5N1 bird flu isolated in Texas shows mutations enabling better replication in human cells and causing more severe disease in mice compared to a bovine strain. While the virus isn’t ...

Blood does more than just carry oxygen and nutrients. Its many “markers,” known as antigens, can trigger unexpected responses. Most folks have heard about the blood groups A, B, and O, and the Rh ...

One of the earliest strains of bird flu isolated from a human in Texas shows a unique constellation of mutations that enable it to more easily replicate in human cells and cause more severe ...

For 30 years, researchers have known that Huntington's is caused by an inherited mutation in the Huntingtin (HTT) gene, but they didn't know how the mutation causes brain cell death. A study ...

Video: Broad Institute of MIT and Harvard At a glance: Study explains long-standing question of why Huntington’s disease symptoms typically do not appear until midlife even though patients are born ...

This means that the damage has multiple chances to generate harmful mutations, which can lead to cancer. While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms ...

The Garvan team revealed that this is not the case -- rather, the critical trigger is mutations in 'rogue clone' B cells. "This discovery fundamentally changes our understanding of how infections ...

Researchers in the group of Dr. Myriam Charpentier discovered a mutation in a gene in the legume Medicago truncatula that reprograms the signaling capacity of the plant so that it enhances ...
