Coronavirus researchers led by Professor Rolf Hilgenfeld of the University of Luebeck and PD Dr. Albrecht von Brunn of the Ludwig-Maximilian Universitaet (LMU) in Munich have discovered how SARS viruses enhance the production of viral proteins in infected cells, so that many new copies of the virus can be generated.Continuar Leyendo
Children with weakened immune systems have not shown a higher risk of developing severe COVID-19 infection despite commonly displaying symptoms, a new study suggests. Highfield, April 22, 2021.- a 16-week period which covered the first wave of the pandemic, researchers from Southampton carried out an observational study of nearly 1500Continuar Leyendo
Astronauts who spend extended time in space face stressors such as isolation, confinement, lack of privacy, altered light-dark cycles, monotony and separation from family. Interestingly, so do people who work at international research stations in Antarctica, where the extreme environment is characterized by numerous stressors that mirror those present duringContinuar Leyendo
Monday, NASA’s Ingenuity Mars Helicopter became the first aircraft in history to make a powered, controlled flight on another planet. The Ingenuity team at the agency’s Jet Propulsion Laboratory in Southern California confirmed the flight succeeded after receiving data from the helicopter via NASA’s Perseverance Mars rover at 6:46 a.m.Continuar Leyendo
A new study led by researchers at Johns Hopkins and the University of Pennsylvania uses computer modeling to suggest that eviction bans authorized during the COVID-19 pandemic reduced the infection rate and not only protected those who would have lost their housing but also entire communities from the spread ofContinuar Leyendo
It has been known for about a year that minks can become infected with SARS-CoV-2. The virus had been transmitted from humans to farmed mink and mutated in infected animals. Mutations were acquired in the spike protein, which is crucial for the entry of the virus into host cells andContinuar Leyendo
Researchers at Aalto University have developed a new device for spintronics. The results have been published in the journal Nature Communications, and mark a step towards the goal of using spintronics to make computer chips and devices for data processing and communication technology that are small and powerful. Helsinki, AprilContinuar Leyendo
Some survivors of ebolavirus outbreaks make antibodies that can broadly neutralize these viruses — and now, scientists at Scripps Research have illuminated how these antibodies can disable the viruses so effectively. The insights may be helpful for developing effective therapies. Los Angeles, April 19, 2021.- Ebolavirus is a family ofContinuar Leyendo
La pequeña aeronave de la NASA voló durante 39 segundos, ante la atenta mirada de los ingenieros en California, en todo un hito en la historia aeroespacial. Pasadena, Calif., April 19, 2021.- Un pequeño vuelo para un helicóptero, un gran viaje para la Humanidad. Así podría definirse lo ocurrido esteContinuar Leyendo
