As the COVID-19 pandemic rages on, researchers are working overtime to develop vaccines and therapies to thwart SARS-CoV-2, the virus responsible for the disease Many efforts focus on the coronavirus spike protein, which binds the angiotensin-converting enzyme 2 (ACE2) on human cells to allow viral entry. Now, researchers reporting in ACS Central Science have uncovered [...]
A research team in Hungary pinched the coronavirus with a fine needle to measure how much force it could take before popping like a balloon. It did not. The native virion of Sars-CoV-2 – a complete virus particle – was only about 80 nanometres wide, and the needle tip was much smaller than that. The [...]
Headaches, confusion and delirium experienced by some Covid-19 patients could be the result of the coronavirus directly invading the brain, according to a study published Wednesday. The research is still preliminary – but offers several new lines of evidence to support what was previously a largely untested theory. According to the paper, which was led [...]
By Boris M | Published in Coronavirus During the COVID-19 pandemic, there will be a lot of information about the virus and its effects on mental health. That’s because coronavirus and the social, financial and psychological implications it carries can seriously impact one’s mental wellbeing. Government legislation, mass media coverage, and the increasing global death toll [...]
When COVID-19 spread around the globe this year, David Montefiori wondered how the deadly virus behind the pandemic might be changing as it passed from person to person. Montefiori is a virologist who has spent much of his career studying how chance mutations in HIV help it to evade the immune system. The same thing [...]
A serious illness suffered by an Oxford University coronavirus vaccine trial participant was most likely “life-threatening”, a bioethics researcher says. But that doesn’t mean the clinical trials will be scrapped. AstraZeneca and Oxford University have suspended the late-stage study after a participant in Britain experienced what has been called a serious adverse reaction. Dr Xavier Symons, [...]
There are currently a number of potential coronavirus vaccines being researched. But once a successful one has been developed, it is likely to be in short supply. So how do we decide who to allocate the vaccines to, and how to distribute them across countries? A team of global health experts have proposed a new, three-phase [...]
Analysis of seven trials finds dexamethasone and hydrocortisone should be given in severe cases. Studies around the world have confirmed that steroids can save lives in the Covid-19 pandemic, leading to new recommendations from the World Heath Organization that doctors should give them to severely ill patients. In June, the Recovery trial run in [...]
Experts say strong evidence of efficacy needed to avoid approval of inferior vaccines. The rush to immunise populations against Covid-19 could lead to the rollout of a vaccine that is not very effective and risk worsening the pandemic, leading scientists have said. Politicians and commercial companies are competing to be the first to license [...]
The COVID-19 pandemic has dominated the news cycle for the better part of 2020. As guidelines are continually updated to reflect changes in our understanding of how the virus spreads, it is critical people receive accurate, credible information that encourages prevention. Understanding the factors that influence these messages’ effectiveness is crucial. A group of [...]
