New SARS-CoV-2 variants are spreading rapidly, and there are fears that current COVID-19 vaccines won’t protect against them. The latest in a series of structural studies of the SARS-CoV-2 variants’ “spike” protein, led by Bing Chen, PhD, at Boston Children’s Hospital, reveals new properties of the Alpha (formerly U.K.) and Beta (formerly South Africa) variants.…

A study from UCLA neurologists challenges the idea that the brain recruits existing neurons to take over for those that are lost from stroke. It shows that in mice, undamaged neurons do not change their function after a stroke to compensate for damaged ones. A stroke occurs when the blood supply to a certain part…

A new study by UC Davis researchers confirms the low likelihood that SARS-CoV-2 contamination on hospital surfaces is infectious. The study, published June 24 in PLOS ONE, is the original report on recovering near-complete SARS-CoV-2 genome sequences directly from surface swabs. “Our team was the first to demonstrate that SARS-CoV-2 virus sequences could be identified…

BOSTON – At the recent 2021 Annual Scientific Sessions of the American Diabetes Association, researchers from Massachusetts General Hospital (MGH) presented positive updates on their trials of the bacillus Calmette-Guérin (BCG) vaccine to safely and significantly lower blood sugars. In type 1 diabetes, an autoimmune disease which currently has no cure, T cells attack the…

In 2018, Dr. Claudia Gonzaga-Jáuregui, who years before had completed her doctorate studies in Dr. James R. Lupski’s lab at Baylor College of Medicine, received an email from an editor at Elsevier’s Academic Press with a proposal that immediately caught her attention. “The editor was considering adding a title on genomics of rare diseases to…

After suffering a stroke, patients often are unable to use the arm on their affected side. Sometimes, they end up holding it close to their body, with the elbow flexed. In a new study, Northwestern University and Shirley Ryan AbilityLab researchers have discovered that, in an attempt to adapt to this impairment, muscles actually lose…
