Physicists, chemists and immunologists at McMaster University have teamed up to modify red blood cells to transport viral agents which can safely trigger the immune system to protect the body against SARS-CoV-2, creating a promising new vehicle for vaccine delivery. Hamilton, March 13, 2022.- Developing new strategies and vaccine technologiesContinuar Leyendo
Danish and Swedish researchers have dated the enormous Hiawatha impact crater, a 31 km-wide meteorite crater buried under a kilometer of Greenlandic ice. The dating ends speculation that the meteorite impacted after the appearance of humans and opens up a new understanding of Earth’s evolution in the post-dinosaur era. Copenhagen,Continuar Leyendo
Irish and German scientists have just identified how specific immune cells can work together in fat to cause inflammation that leads to weight gain and obesity. Their work pinpoints new avenues to exploit the regulation of that inflammation in fat tissue, thereby suggesting new ways to manage obesity [Wednesday 9thContinuar Leyendo
Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers at Leiden Observatory in the Netherlands have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor of largerContinuar Leyendo
Even light-to-moderate drinking is associated with harm to the brain, according to a new study. Researchers analyzed data from more than 36,000 adults that found a link between drinking and reduced brain volume that begins at an average consumption level of less than one alcohol unit a day — theContinuar Leyendo
Investigators from Weill Cornell Medicine and Memorial Sloan Kettering Cancer Center have discovered how a drug for multiple sclerosis interacts with its targets, a finding that may pave the way for better treatments. New Yor, March 06, 2022.- The study, published Feb. 8 in Nature Communications, details the precise molecularContinuar Leyendo
Take a cell-deep tour of a brain afflicted with Alzheimer’s disease, and you will find minuscule clumps of protein that seem suspicious. Ever since the 1980s, when neuroscientists began identifying these protein tangles, researchers have discovered that other brain diseases have their own tangled-protein signatures. New York, March 06, 2022.-Continuar Leyendo
Only one currently authorized antibody treatment retains its activity against all Omicron subvariants, according to new research by scientists at Columbia University and the University of Hong Kong. The study also shows that the effectiveness of mRNA vaccines is reduced against all three subvariants of Omicron. New York, March 04,Continuar Leyendo
The innate immune system plays a crucial role in regulating host-microbe interactions, and especially in providing protection against pathogens that invade the mucosa. Using an intestinal infection model, scientists from the Institut Pasteur and Inserm discovered that innate effector cells — group 3 innate lymphoid cells — act not onlyContinuar Leyendo
Scientists developed a neural network deep learning technique to extract hidden turbulent motion information from observations of the Sun. Tests on three different sets of simulation data showed that it is possible to infer the horizontal motion from data for the temperature and vertical motion. This technique will benefit solarContinuar Leyendo
