by Allessandra Dicorato, Broad Institute of MIT and Harvard Credit: Susanna Hamilton, Broad Communications New research suggests age-related changes in blood cell chromosomes are a marker of impaired immunity. A person’s risk of severe infections increases dramatically as they grow older, but scientists do not yet understand how age might be linked to weakened immunity. Now, research shows...

Researchers at the University of Sydney’s Charles Perkins Centre have conducted the largest-ever study of nutrient interactions by examining the health of mice on 33 different diets containing various combinations of protein to carbs, and different sources of carbohydrate. They found that a low-protein (10% of...

by Hiroshima University After looking at the fate of transplanted spermatogonial stem cells up-close at single-cell resolution, the researchers discovered that only a small fraction repopulates as working spermatogonia. They developed a new strategy that introduces a chemical inhibitor to increase the odds of sperm stem cells choosing a fate of self-renewal. Credit: Pexels The ability...

The study published today online in Nature Neuroscience. Because of the...
QUEEN MARY UNIVERSITY OF LONDON A minimally-invasive procedure that targets the nerves near the kidney has been found to significantly reduce blood pressure in hypertension patients, according to the results of a global multicentre clinical trial led in the UK by researchers at Queen Mary University of London and Barts Health NHS Trust. The study,...
