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 ...

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 ...

Study finds surprising way that genetic mutation causes Huntington's disease, transforming understanding of the disorder Researchers studying brain cells from Huntington's patients show that the ...

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 ...

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 ...

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 ...

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 ...

In early December 2024, a group of researchers published an article in the journal Science, entitled "A single mutation in bovine influenza H5N1 hemagglutinin switches specificity to human receptors".
