Within weeks, scientists at the Walter Reed Army Institute of Research expect to announce that they have developed a vaccine that is effective against COVID-19 and all its variants, even Omicron, as well as previous SARS-origin viruses that have killed millions of people worldwide. The achievement is the result of almost two years of [...]
Two-dimensional (2D) nanomaterials like graphene have received great research attention for several years, but a new generation of atom-thick materials – MXenes – has recently captured the interest of materials science researchers and nanotechnology developers alike. Synthesizing MXene Nanomaterials MXenes are 2D nanomaterials that exhibit high conductivity, high surface area, high functionalization, a site [...]
The US Food and Drug Administration (FDA) on Thursday authorized Merck's Covid pill for high risk adults amid a winter surge of cases driven by the highly infectious Omicron variant. The decision to grant an emergency use authorization came a day after the agency gave a green light to a similar but more effective [...]
Today, the U.S. Food and Drug Administration issued an emergency use authorization (EUA) for Pfizer’s Paxlovid (nirmatrelvir tablets and ritonavir tablets, co-packaged for oral use) for the treatment of mild-to-moderate coronavirus disease (COVID-19) in adults and pediatric patients (12 years of age and older weighing at least 40 kilograms or about 88 pounds) with positive results [...]
The omicron variant of the SARS-CoV-2 virus, discovered just a few weeks ago, is poised to dominate Covid-19 cases around the world. It’s a stunning new twist to the pandemic saga that has countries scrambling to prepare. In places like South Africa and the United Kingdom where omicron has been spreading fast, Covid-19 cases [...]
A novel approach to testing for the presence of the virus that causes COVID-19 may lead to tests that are faster, less expensive, and potentially less prone to erroneous results than existing detection methods. Though the work, based on quantum effects, is still theoretical, these detectors could potentially be adapted to detect virtually any [...]
A new study from Columbia researchers, in collaboration with scientists at the University of Hong Kong, adds more evidence that the omicron variant can evade the immune protection conferred by vaccines and natural infection and suggests the need for new vaccines and treatments that anticipate how the virus may soon evolve. The findings, which [...]
Nanodiamonds may be tiny, but they can help with one of the biggest problems facing humanity today: Climate change. Hydrogen, a clean-burning fuel, leaves nothing but water when consumed. Many countries view hydrogen as a way to a zero-carbon future, but switching to a hydrogen economy requires its production to be much more affordable [...]
A bottom-up approach to produce copper oxide (CuO) nanoparticles on hydrophilic graphene oxide (GO) nanosheets has been employed in the latest research published in Journal of Material Science: Materials in Medicine. The CuO/GO nanocomposite was created by combining two different predecessors, copper nitrate and citric acid, with occasional mixing of GO solutions. Importance of Copper [...]
Led by the University of Oxford, a team of UK-based researchers have today reported results of the largest ever study to compare the risks of cardiovascular events, such as myocarditis, pericarditis, and cardiac arrhythmia, between different vaccines and COVID-19 infection, and the first to investigate the association between cardiac events and the Oxford-AstraZeneca vaccine.
