Study reveals new therapeutic target for C. difficile infection
A new study paves the way for the development of next generation therapeutics for the prevention and treatment of Clostridioides difficile infection (CDI), the most frequent cause of healthcare-acquired gastrointestinal infections and death in develo.....»»
Researchers identify microbe that protects bees from fungal infections
Honey bees are the most economically important agricultural pollinators on Earth, but their populations have been in decline for decades. At Indiana University, researchers are investigating how to use the honey bee's natural microbiome to keep them.....»»
"Nanodecoy" therapy binds and neutralizes SARS-CoV-2 virus
Nanodecoys made from human lung spheroid cells (LSCs) can bind to and neutralize SARS-CoV-2, promoting viral clearance and reducing lung injury in a macaque model of COVID-19. By mimicking the receptor that the virus binds to rather than targeting th.....»»
Study finds potentially druggable process of SARS-CoV-2 replication
Of all the proteins of the SARS-CoV-2 virus (the pathogen that causes COVID-19), the spike protein is the one that gets the most attention. This attention is well-deserved—the spike protein is essential for latching on to cells and infecting a host.....»»
COVID-19 cluster infections at Taiwan IC firms put under control
COVID-19 cluster infections among migrant workers at King Yuan Electronics and several other Taiwan-based IC companies' factory sites in Miaoli of northern Taiwan have been brought under control......»»
Graphene can be used to detect COVID-19 quickly, accurately
Researchers at the University of Illinois Chicago have successfully used graphene—one of the strongest, thinnest known materials—to detect the SARS-CoV-2 virus in laboratory experiments. The researchers say the discovery could be a breakthrough i.....»»
Study confirms safety and effectiveness of COVID-19 vaccination in people with cancer
In a review of 200 patients with a wide spectrum of cancer diagnoses, researchers found that after full vaccination, 94 percent of patients overall demonstrated seroconversion, which was determined by the presence of antibodies to the SARS-CoV-2 spik.....»»
Compound blocks SARS-CoV-2 and protects lung cells, study finds
Researchers report that Elovanoids, bioactive chemical messengers made from omega-3 very-long-chain polyunsaturated fatty acids, may block the virus that causes COVID-19 from entering cells and protect the air cells (alveoli) of the lung......»»
Monoclonal antibody therapy for COVID-19 safe, effective for transplant patients, study finds
Treating transplant patients with mild to moderate cases of COVID-19 with monoclonal antibodies is safe and helps prevent serious illness, according to a new study. These results are especially important because transplant patients who are infected w.....»»
SARS-CoV-2 protease cuts human proteins; Possible link to COVID-19 symptoms
The SARS-CoV-2 papain-like protease (PLpro) plays an essential role in processing viral proteins needed for replication. In addition, the enzyme can cut and inactivate some human proteins important for an immune response. Now, researchers have found.....»»
Common diabetes drug shows promise as treatment for COVID-19 lung inflammation
Researchers identify the molecular mechanism for the anti-inflammatory activity of diabetes drug metformin and, in mouse studies, say it prevents lung inflammation in animals infected with SARS-CoV-2, the virus that causes COVID-19......»»
A new culprit in antibacterial resistance: Cysteine persulfide
Scientists have developed a new, highly sensitive analytical method that can detect degraded beta-lactam antibacterial agents used in the treatment of bacterial infections. With this method, researchers found that reactive sulfur species produced by.....»»
Global weight of all active SARS-CoV-2 viruses is between 0.1 and 10 kilograms
A combined team of researchers from the Weizmann Institute of Science in Israel and the California Institute of Technology in the U.S. has calculated the weight of all the SARS-CoV-2 viruses infecting people around the world at any given time. In the.....»»
How viruses mutate and create new variants
As the COVID-19 pandemic continues, new variants of the SARS-CoV-2 virus pop up, and some lead to increasing infections. The main new variants—named Alpha, Beta, and Gamma and first identified in Britain, South Africa, and India, respectively—hav.....»»
Carbon-based nanomaterials show promising results against SARS-CoV-2 and 12 other viruses
Professor Ángel Serrano, principal investigator at the Biomaterials and Bioengineering Laboratory of the Catholic University of Valencia (UCV), recently published an article in journal ACS Nano, from the American Chemical Society, which shows that c.....»»
Pandemic effects on small companies
Everyone the world over has been left unaffected by the emergence of a novel coronavirus, named SARS-CoV-2 in late 2019, which led to the current COVID-19 pandemic. Our lives have been disrupted enormously by the medical, social, and economic implica.....»»
Surging COVID-19 infections in Taiwan and Malaysia could further constraint notebook component supply
With Asia Pacific countries such as Taiwan and Malaysia witnessing COVID-19 infections surging, sources from the upstream supply chain believe shortages of notebook components could worsen......»»
Highlights of the day: PC component shortage may worsen
The PC sector has endured months of shortage of components, and the recent surges in COVID infections in Taiwan and Malaysia are threatening to worsen the component shortfall. Demand for notebooks is expected to remain robust through the end of 2021,.....»»
How COVID-19 wreaks havoc on human lungs
Scientists have published the first detailed atomic-level model of the SARS-CoV-2 'envelope' protein bound to a human protein essential for maintaining the lining of the lungs. The findings may speed the search for drugs to block the most severe effe.....»»
Preclinical study suggests new approach to reduce COVID-19 death among the elderly
