Rising chorus of concern over Sputnik V vaccine stems from opaque development and lack of mass-testing. In 1977 Scott Halstead, a virologist at the University of Hawaii, was studying dengue fever when he noticed a now well-known but then unexpected feature of the disease. Animals that had already been exposed to one of the [...]

Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases for the last three decades and an expert on pandemics for the last four decades, has been optimistic on a vaccine arriving at the end of 2020 or in early 2021, but he has also cautioned the public on their expectations for [...]

he United States has recorded 5 million confirmed coronavirus cases, while almost 20 million people are infected worldwide, according to Johns Hopkins University. Outside of the US, Brazil recorded more than 3 million cases, while Italy, which was ground zero of Europe's epidemic, still has one of the world's highest official death tolls at [...]

According to the first phase results, 90 per cent of the patients'lungs are still in a damaged state, which means their lungs ventilation and gas exchange functions have not recovered 90% of an example gathering of coronavirus-recuperated patients from a conspicuous medical clinic in China's Wuhan city where the pandemic broke out has detailed [...]

There are currently 25 vaccines to fight COVID-19 in clinical evaluation, another 139 vaccines in a pre-clinical stage, and many more being researched. But many of those vaccines, if they are at all successful, might not produce an immune response in portions of the population. That's because some people's bodies will react differently to the [...]

A new class of nanosensor developed in Brazil could more accurately identify dengue and Zika infections, a task that is complicated by their genetic similarities and which can result in misdiagnosis. The technique uses gold nanoparticles and can "observe" viruses at the atomic level, according to a study published in Scientific Reports. Belonging to the [...]

Scientists investigating the evolution of the virus that causes Covid19 say that its mutation seems to be directed by human proteins that degrade it, but natural selection of the virus enables it to bounce back. The findings could help in the design of vaccines against the virus. All organisms mutate. You were for example [...]

Biomedical engineers at the Tufts University School of Engineering have developed tiny lipid-based nanoparticles that incorporate neurotranmitters to help carry drugs, large molecules, and even gene editing proteins across the blood-brain barrier and into the brain in mice. The innovation, published today in Science Advances, could overcome many of the current limitations encountered in [...]

UC San Diego recently announced that its health radiologists and other physicians are now leveraging artificial intelligence (AI) to augment lung-imaging analysis in a clinical research study aimed at COVID-19 lung imaging analysis. The cause of death for most COVID-19 patients is pneumonia, which often requires long hospital stays in intensive care units and assistance breathing [...]

The hubbub around mutations in the virus that causes COVID-19—and how they might make it more infectious—has been around since the early phase of the pandemic. A preprint study about a particular mutation involving the “spikes” studding the SARS-CoV-2 pathogen had previously drawn attention, and that investigation has now been peer-reviewed and published in Cell.
