An antiviral surface coating technology sprayed on face masks could provide an extra layer of protection against COVID-19 and the flu. The coating developed at The University of Queensland has already proven effective in killing the virus that causes COVID-19, and shows promise as a barrier against transmission on surfaces and face masks. UQ's Australian Institute [...]
Key Points Monash researchers have developed a method to prepare elongated nanocrystals to deliver therapeutic drugs Elongated nanocrystals can carry a high payload of drugs to potentially increase drug targetability and also decrease dosage frequency and side effects The researchers used a combination of deuteration, X-ray and neutron techniques at ANSTO to distinguish the [...]
It has been 30 years since the last new class of antibiotic was introduced to the market. All the existing drugs are essentially variations on a theme: they kill bacteria, in similar ways. Some burst cells walls, others block DNA replication. But the bacteria are swiftly evolving to survive those chemical attacks – and [...]
With more than 18 months of the pandemic in the rearview mirror, researchers have been steadily gathering new and important insights into the effects of COVID-19 on the body and brain. These findings are raising concerns about the long-term impacts that the coronavirus might have on biological processes such as aging. As a cognitive neuroscientist, my past research has [...]
The COVID-19 pandemic triggered life expectancy losses not seen since World War II in Western Europe and exceeded those observed around the dissolution of the Eastern Bloc in central and Eastern European countries, according to research published [27 September], led by scientists at Oxford’s Leverhulme Centre for Demographic Science. The research team assembled an unprecedented dataset on [...]
Within a day of testing positive for covid-19 in June, Miranda Kelly was sick enough to be scared. At 44, with diabetes and high blood pressure, Kelly, a certified nursing assistant, was having trouble breathing, symptoms serious enough to send her to the emergency room. When her husband, Joe, 46, fell ill with the [...]
A technology developed at Vanderbilt University Medical Center has led to the discovery of an "ultra-potent" monoclonal antibody against multiple variants of SARS-CoV-2, the virus responsible for COVID-19, including the delta variant. The antibody has rare characteristics that make it a valuable addition to the limited set of broadly reactive antibody therapeutic candidates, researchers [...]
Research has found a significant fall in levels of antibodies against SARS-CoV-2, the virus that causes COVID-19, 6 months after the second dose of the Pfizer-BioNTech vaccine. Clinical evidence also suggests that the risk of getting a “breakthrough” infection gradually increases in the months after vaccination. Despite declines in antibody levels, other branches of [...]
Are the COVID vaccines substantially different from/inferior to other vaccines in terms of their effectiveness? The issue raised, and I'm mostly paraphrasing here, is this: Most vaccines (e.g. measles, smallpox) have efficacy defined such that (for example) a 95% effective vaccine means that for a group of thoroulghly exposed people, 95% of the vaccinated [...]
The EVONANO platform allows scientists to grow virtual tumors and use artificial intelligence to automatically optimize the design of nanoparticles to treat them. The ability to grow and treat virtual tumors is an important step towards developing new therapies for cancer. Importantly, scientists can use virtual tumors to optimize design of nanoparticle-based drugs [...]
