by Alzheimer’s Research UK Credit: Unsplash/CC0 Public Domain Researchers in France have found a link between eating more fish and a lower risk of vascular brain disease. Vascular brain disease involves damage to blood vessels in the brain and is a risk factor for vascular dementia and stroke. The research is published today in the...
by University College London Credit: Pixabay/CC0 Public Domain The damage caused by COVID-19 to the lungs’ smallest blood vessels has been intricately captured using high-energy X-rays emitted by a special type of particle accelerator. Scientists from UCL and the European Synchrotron Research Facility (ESRF) used a new revolutionary imaging technology called Hierarchical Phase-Contrast Tomography (HiP-CT),...
By UNIVERSITY OF CAMBRIDGE OCTOBER 30, 2021 For the first time, researchers have used human data to quantify the speed of different processes that lead to Alzheimer’s disease and found that it develops in a very different way than previously thought. Their results could have important implications for the development of potential treatments. The international team, led by the...
by University of Missouri Kimberly Powell. Credit: MU Sinclair School of Nursing The COVID-19 pandemic caused nursing homes to rapidly change their policies overnight. Telehealth was instantly adopted widely in an effort to reduce stress on the health care system by keeping residents safe and avoiding unnecessary transfers to already-overwhelmed hospitals. A new study at...

The findings in mice, published in the journal Med, are the first to...
by Baylor College of Medicine Credit: CC0 Public Domain Researchers at Baylor College of Medicine have uncovered a more detailed picture of how the intestinal epithelium—the lining of the intestines—heals itself after infection with rotavirus. A meticulous single-cell analytical approach to study the repair process in an animal model revealed that the damaged epithelium contains...
by Perelman School of Medicine at the University of Pennsylvania Credit: CC0 Public Domain Researchers at Penn Medicine have made a major advance in understanding the biology of a common, puzzling, and often fatal heart disorder, dilated cardiomyopathy (DCM), which features the enlargement of the heart and a progressive decrease in its function, for reasons...

By Rich Haridy November 02, 2021 In a dozen human subjects the brain implant improved performance on cognitive control testssqback/Depositphotos A landmark pilot study has demonstrated how a brain implant can deliver targeted bursts of electrical stimulation to improve cognitive functions. In real-time the implant senses electrical biomarkers of cognitive deficits and responds by stimulating...
The researchers found that patients who used proton pump inhibitors (PPIs)—a class of drugs commonly prescribed to treat heartburn, acid reflux, and ulcers—were more likely to have smaller probing depths in the gums (the gap between teeth and gums). When gums are healthy, they fit snuggly against the teeth. However, in the presence of harmful bacteria, the...
