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
Nearly 90 percent of COVID-19 patients who qualified for, but did not receive, ECMO (extracorporeal membrane oxygenation) due to a shortage of resources during the height of the pandemic died in the hospital, despite being young with few other health issues, according to a study published in the American JournalContinuar Leyendo
Scientists at the Max Planck Institute for Medical Research in Heidelberg and their collaborators at the Max Planck Bristol Center for Minimal Biology at the University of Bristol have developed a new approach to study Sars-CoV-2. For systematic and standardized research of Sars-CoV-2 they built minimalistic synthetic virus particles whereContinuar Leyendo
A spectacular head-on collision between two galaxies, known as Arp 143, has fueled the unusual triangular-shaped star-formation frenzy as captured by the NASA/ESA Hubble Space Telescope. París, Feb 23, 2022.- The interacting galaxy duo Arp 143 contains the distorted, star-forming spiral galaxy NGC 2445, at right, along with its lessContinuar Leyendo
Approximately 80 miles from the westernmost reach of China’s Great Wall, paleontologists found relics of an even more ancient world. Over the last two decades, teams of researchers unearthed more than 100 specimens of fossil birds that lived approximately 120 million years ago, during the time of the dinosaurs. However,Continuar Leyendo
T-cell responses directed against the receptor-binding domain of the SARS-CoV-2 spike protein were associated with protection from SARS-CoV-2 infection in vaccinated individuals with or without cancer, with lower T-cell responses observed in patients with blood cancers, according to results from a study published in Cancer Discovery, a journal of theContinuar Leyendo
