Researchers examine the evolutionary race between SARS-CoV-2 and human defenses

Researchers have analyzed this evolution of the virus based on evolutionary ecology theory. Using the virus genomes available in the Global Initiative on Sharing Avian Influenza Data (GISAID) database, the researchers focused their inquiry on mutations in the receptor-binding domain (RBD) on the spike protein of SARS-CoV-2.

Researchers develop novel test that screens for SARS-CoV-2 variants of concern

A team of scientists from the United States has recently developed a single-tube duplex molecular assay for rapid detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants containing E484K and N501Y spike mutations.

Imported COVID-19 cases responsible for spread of the UK and Brazil SARS-CoV-2 variants in Italy

A new study examines a major consequence of the second wave of COVID-19 infection—namely, the rapid emergence of new viral lineages and variants.

Single dose of Pfizer and Oxford vaccines shows 60% efficacy in elderly care home residents

A new study deals with the effect of two widely used vaccines in eliciting humoral immunity against the virus in this group. These are the Oxford/AstraZeneca viral-vectored vaccine (ChAdOx1 nCoV-19), and the Pfizer/BioNTech’s messenger RNA-based vaccine (BNT162b2). Both express the viral spike antigen, and both are currently being employed in the UK’s vaccination program.

New system facilitates real-time imaging of biological, pathological processes

Researchers at the Federal University of São Carlos (UFSCar) in the state of São Paulo, Brazil, have developed a novel far-red light-emitting luciferin-luciferase system that is more efficient than those available commercially. An article on the subject is published in the International Journal of Molecular Sciences.

Study shows how innate valence is encoded

Since the beginning of the pandemic, a loss of smell has emerged as one of the telltale signs of COVID-19. Though most people regain their sense of smell within a matter of weeks, others can find that familiar odors become distorted.

Study reveals the structure of key enzyme that may advance cancer research

In order to develop more effective drugs against a range of cancers, researchers have been investigating the molecular structure of many diseased-linked enzymes in the body. An intriguing case in point is Taspase 1, a type of enzyme known as a protease.

FDA-approved cancer drug blunts SARS-CoV-2 protein's detrimental effects

University of Maryland School of Medicine (UMSOM) researchers have identified the most toxic proteins made by SARS-COV-2 - the virus that causes COVID-19 – and then used an FDA-approved cancer drug to blunt the viral protein's detrimental effects. In their experiments in fruit flies and human cell lines, the team discovered the cell process that the virus hijacks, illuminating new potential candidate drugs that could be tested for treating severe COVID-19 disease patients.

Intelligent near-infrared vein scanner may make blood draws much easier

Researchers from Skoltech have developed an early prototype of a medical imaging system that uses neural networks to analyze near-infrared images of veins and project a venous pattern onto a patient's body - this may make blood draws much easier and less of a nuisance for patients with difficult access to veins.
