Credit: Garvan Institute of Medical Research Research led by the Garvan Institute of Medical Research has for the first time mapped the unique genetic profile of the skeleton’s ‘master regulator’ cells, known as osteocytes. The study published today in Nature Communications outlines the genes that are switched on...

Elson, M.D., demonstrated a potential preventive treatment for Crohn’s disease, a form of inflammatory bowel disease. He used a mouse model that included immune-reactive T cells from patients with Crohn’s disease...
by Trinity College Dublin Credit: CC0 Public Domain A new study from scientists at The Irish Longitudinal Study on Aging (TILDA) at Trinity College Dublin reveals important findings, indicating that being overweight or obese significantly reduces blood flow in the brain. The study also shows that increased physical activity can positively modify, or even negate, this...

By NATALIE RAHHAL U.S. HEALTH EDITOR PUBLISHED: 19:08 EDT, 4 May 2021 | UPDATED: 19:12 EDT, 4 May 2025 Nearly half of older millennials already have chronic health conditions, a new survey suggests. Some 44 percent of people born between 1981 and 1988 have already been diagnosed with at least one chronic medical condition, according to the CNBC/Harris poll. The...
TRINITY COLLEGE DUBLIN Researchers at AMBER, the SFI Centre for Advanced Materials and BioEngineering Research, and from Trinity’s School of Physics, have developed next-generation, graphene-based sensing technology using their innovative G-Putty material. The team’s printed sensors are 50 times more sensitive than the industry standard and outperform other comparable nano-enabled sensors in an important metric seen as...
by Indiana University School of Medicine Credit: CC0 Public Domain Scientists believe a stomach-specific protein plays a major role in the progression of obesity, according to new research in Scientific Reports. The study, co-authored by an Indiana University School of Medicine researcher, could help with development of therapeutics that would help individuals struggling with achieving and...
by Johns Hopkins University School of Medicine New SaferSeqS technology detects rare mutations in blood in a highly efficient manner and reduces the error rate. Credit: Elizabeth Cooke Next-generation gene sequencing (NGS) technologies—in which millions of DNA molecules are simultaneously but individually analyzed—theoretically provides researchers and clinicians the ability to noninvasively identify mutations in the blood...
By Michael Irving May 03, 2021 A new genetic engineering tool called Retron Library Recombineering (RLR) could be a cleaner alternative to CRISPR CRISPR-Cas9 is a revolutionary gene-editing tool, but it’s not without its downsides. Now, scientists at Harvard have demonstrated an alternative genetic engineering system called Retron Library Recombineering (RLR), which works without cutting DNA...
