A nasal COVID-19 vaccine blocks transmission of the virus, according to an animal study. The findings suggest that vaccines delivered directly to the nose or mouth could play a critical role in containing the spread of respiratory infections. The lightning-fast development of COVID-19 vaccines just months after the virus appeared was a triumph of modern

Two of the closest known relatives to SARS-CoV-2 -- a pair of bat coronaviruses discovered by researchers in Laos -- may transmit poorly in people despite being genetically similar to the COVID-19-causing virus, a new study reveals. The findings provide clues as to why some viruses have greater 'pandemic potential' than others and how researchers

Dexamethasone is one of the most important drugs in the treatment of severe COVID-19, but patients respond very differently to the therapy. Researchers have now discovered how the cortisone compound influences the impaired inflammatory response and which patients benefit from it. Their method uses so-called single-cell analyses and raises hopes for a precise prediction tool
Post-COVID research has extensively focused on the efficacy of internal travel restrictions and cross-border travel has received less attention due to challenges in accessing quality data. In a major multidisciplinary collaboration effort across Finland, Sweden, Norway, and Denmark, a group of researchers -- including mathematicians, physicists and computer scientists -- have published a pioneering study
A new study sheds light on factors that may have predisposed some patients to recover more slowly after COVID. Early in the pandemic, many people who had SARS-Cov-2 infection or COVID-19 began to report that they couldn't shake off their symptoms even after a month or more -- unusually long for a viral infection of
During the COVID-19 pandemic, at-home antigen tests became widely accepted for detecting infection. In a new study, researchers looked into the benefits of using at-home antibody tests to detect immunity and to make decisions about the need for a COVID-19 booster shot -- something that may be of particularly relevance for those at high risk
Recently, scientists found that some people who suffered from COVID-19 had auto-antibodies targeting their own type 1 interferons, which are important immune signaling proteins. Now, researchers conducted an in-depth study on 123 Japanese COVID-19 patients to clarify just how common these auto-antibodies are among severe cases and how they affect the immune system. Their findings
A new study shows that people with COVID-19 who used cannabis were more likely to be hospitalized and require intensive care than those who did not use the drug. As the deadly disease that came to be known as COVID-19 started spreading in late 2019, scientists rushed to answer a critical question: Who is most
A new study provides insight on how to make a new generation of rapid tests, including COVID, flu, RSV, and all-in-one tests, work better. Peek in medicine cabinets across the U.S. and you'll find stacks of leftover COVID-19 tests. When symptoms arise, so do questions: When should I test? How accurate is it really? And
Combining genomic data and human travel patterns over a 14-year period in South Africa reveals key insights into the spread, evolution and resistance patterns of a major bacterium behind pneumonia and meningitis globally. A new way to map the spread and evolution of pathogens, and their responses to vaccines and antibiotics, will provide key insights
Since the outset of the COVID-19 pandemic, 10 to 30 per cent of the general population has experienced some form of virus-induced cognitive impairment, including trouble concentrating, brain fog or memory loss. This led a team of researchers to explore the mechanism behind this phenomenon and pinpoint a specific protein that appears to be driving
A more accurate way to scan for tuberculosis (TB) has been developed, using positron emission tomography (PET). The team has developed a new radiotracer, which is taken up by live TB bacteria in the body. Radiotracers are radioactive compounds which give off radiation that can be detected by scanners and turned into a 3D image.
Children who are not considered 'school ready' by their teachers are more than twice as likely to become persistently absent at some point in their education, according to a new study.

Participants. The study found that changes in sleep patterns, such as increased nighttime wakefulness, could be indicative of these health issues. This can be a game-changer in early detection and prevention of these conditions. With the help of a sleep tracker, individuals can potentially identify and address health concerns before they become serious problems. This research highlights the potential of sleep tracking technology to revolutionize healthcare and improve overall well-being
