The highly transmissible delta variant of SARS-CoV-2, the coronavirus causing the disease COVID-19, is now present in 124 countries and will become the dominant strain globally in the coming months as it is outcompeting other variants, the World Health Organization said Wednesday. The variant was detected in 13 new countries in the week ending [...]
Scientists have backed proposals for Covid boosters in the autumn after blood tests on hundreds of people revealed that protective antibodies can wane substantially within weeks of second vaccine shots being given. Falls in antibodies after vaccination are expected and do not necessarily mean people are more vulnerable to disease, but the researchers are [...]
Researchers in the United States have conducted a study showing that the coronavirus disease 2019 (COVID-19) vaccines developed by Pfizer-BioNTech and Moderna generate a coordinated adaptive immune response that is capable of eliciting recall responses to future infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The team from the University of California found [...]
CSIRO, Australia's national science agency, played an important role in evaluating heat-tolerant COVID-19 vaccine formulations developed by the Indian Institute of Science (IISc) and biotech start-up Mynvax—against all current SARS-CoV-2 variants of concern. Published today in the peer-reviewed ACS Infectious Diseases journal, researchers showed the vaccine formulations triggered a strong immune response in mice, [...]
Frank Boehm (NanoApps Medical Inc. Founder) in discussion with Nana Kay in a Wealth Secrets podcast. EP 19. Nanovisaging 2040. From Nana Kay: Nanovisaging 2040: How Synergies between Nanotechnology, Nanomedicine, and AI might Benefit Humanity and Earth. Ladies and Gentlemen, as we continue our journey on the train of enlightenment our next stop is [...]
Canada, like several other countries, has been mixing and matching COVID-19 vaccines for weeks amid safety concerns over the AstraZeneca shot. On Monday, the chief scientist at the World Health Organization (WHO) cautioned against that approach, calling it “a dangerous trend” for a subsequent dose as well as booster shots saying there was insufficient evidence available about the [...]
Scientists have harnessed CRISPR gene-editing technology to block the replication of the novel coronavirus in human cells — an approach that could one day serve as a new treatment for COVID-19. However, the study was performed in lab dishes and has not yet been tested on animals or people, meaning a treatment based on the method [...]
Depositing nanoparticles using the NL50 is now simpler than ever with the pre-loaded optimized recipes for a variety of frequently used materials, including Au, Ag, Pt and Cu. These optimized recipes generate high-quality nano-coatings with premium deposition rates for each material. Moreover, the NL50 also enables the user to vary the size distribution of the deposited nanoparticles [...]
A recent study by scientists from Japanese universities has shown that the shape of cell-derived nanoparticles, known as "extracellular vesicles" (EVs), in body fluids could be a biomarker for identifying types of cancer. In the study, the scientists successfully measured the shape distributions of EVs derived from liver, breast, and colorectal cancer cells, showing [...]
An important lesson for vaccine design Australian scientists researching how our immune system responds to COVID-19 have revealed that those infected by early variants in 2020 produced sustained antibodies, however, these antibodies are not as effective against contemporary variants of the virus. The research is one of the world’s most comprehensive studies of the [...]
