A new paper in Behavioral Ecology finds that wild vampire bats that are sick spend less time near others from their community, which slows how quickly a disease will spread. The research team had previously seen this behavior in the lab, and used a field experiment to confirm it in the wild.
A new artificial intelligence-based score considers multiple factors to predict the prognosis of individual patients with COVID-19 seen at urgent care clinics or emergency departments. The tool, which was created by investigators at Massachusetts General Hospital, can be used to rapidly and automatically determine which patients are most likely to develop complications and need to be hospitalized.
Researchers at Yale University and the Broad Institute of MIT and Harvard screened hundreds of millions of cells exposed to the COVID-19 and MERS viruses and identified dozens of genes that both enable the viruses to replicate in cells and also those that seem to slam the door on the virus. The pro-viral and anti-viral role of these genes will help guide scientists in development of new therapies to combat COVID-19, the researchers say.
A team from the George Washington University will present at the American College of Emergency Physicians annual conference, on results of their study exploring the role of Google searches during the early phase of the COVID-19 pandemic in the United States.
A drug-resistant strain of the Neisseria (N.) gonorrhoeae has emerged around the world with the potential to make gonorrhea untreatable. The currently used screening methods for antimicrobial resistant (AMR) determinants are slow, expensive, and not widely available. In an article in The Journal of Molecular Diagnostics researchers report a rapid and cheap method that can provide real-time surveillance to help control the spread of AMR strains of N. gonorrhoeae.
University of North Carolina School of Medicine scientists have made a curious discovery about a well-known human protein that helps the immune system fight viral infections. The lab of Stan Lemon MD, and colleagues found that one class of viruses actually requires this protein to infect cells and replicate.
Since COVID-19 began its menacing march across Wuhan, China, in December 2019, and then across the world, the SARS-CoV-2 virus has taken a 'whatever works' strategy to ensure its replication and spread. But in a new study published in Evolutionary Bioinformatics, University of Illinois researchers and students show the virus is honing the tactics that may make it more successful and more stable.
Access to more localized data on childhood vaccination coverage, such as at the school or neighborhood levels, could help better predict and prevent measles outbreaks in the United States, according to a new University of Michigan study.
In Physics of Fluids, researchers used a model to understand airborne transmission that is designed to be accessible to a wide range of people, including nonscientists. Employing concepts of fluid dynamics and factors in airborne transmission, they propose the Contagion Airborne Transmission inequality model. While not all factors may be known, it can still be used to assess relative risks. The researchers determined protection from transmission increases with physical distancing in an approximately linear proportion.
New research suggests that the impact of natural and vaccine-induced immunity will be key factors in shaping the future trajectory of the global coronavirus pandemic, known as COVID-19. In particular, a vaccine capable of eliciting a strong immune response could substantially reduce the future burden of infection, according to a study recently published in the journal Science.
