Vaccines likely to be effective against SARS-CoV-2 D614G mutation

The emergence of the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mutation D614G has raised many questions, including whether it will cause the virus to become resistant to the vaccines produced against earlier versions of the virus. A new study published in the journal npj Vaccines in October 2020 shows that this may be an unfounded fear.

Rapid and sensitive detection of SARS-CoV-2 with functionalized magnetic nanoparticles

A recent study published on the preprint server arXiv in October 2020 shows the potential for using functionalized magnetic nanoparticles to detect the presence of the virus in a sample.

Analysis of existing comorbidities and COVID-19 mortality

As the COVID-19 pandemic continues to spread, and research related to potential risk factors for COVID-19 mortality continues, it is becoming clear that individuals with underlying comorbidities have a greater risk of death from COVID-19. The exact contribution of different comorbidities is unclear, however. Now, a new study published in the journal PLOS ONE dissects this topic and may help to quantify the risk posed by specific conditions and offer help with the prognosis.

Pathways contributing to hypercoagulability in severe SARS‐CoV‐2 patients

In a study by researchers explored the possible mechanisms of the clotting disorder, focusing on the role of hypoxia-related activation of coagulation factors; cytokine storm, activation of neutrophils, and the release of neutrophil extracellular traps.

Fetal brain models could predict neurodevelopmental outcomes of COVID-19 exposure

Researchers in the United States and Sweden have created personalized models of fetal brain microglia to investigate the effects of maternal infection on the developing brain, including infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Exciting findings on CD8 T cell response in recovered COVID patients

An international team of scientists has identified novel T cell-recognized epitopes spanning different proteins of severe acute respiratory syndrome coronavirus 2 in COVID-19 recovered patients. The scientists have also revealed phenotypical characteristics of the T cell population.

86 percent of the UK's COVID-19 patients have no symptoms

Many people who contract the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus that causes the coronavirus disease (COVID-19), develop only mild and moderate symptoms. A small fraction of those infected develop severe symptoms, which usually occur in people who are at higher risk due to comorbidities.

Clear and unequivocal evidence we should washing our hands during COVID-19

The study shows that Americans are washing their hands much more they did before the coronavirus pandemic. However, the groups who are less likely to remember to wash their hands on multiple occasions were white people, men, and those between the ages of 18 and 24.

Mass production of SARS-CoV-2 ORF8 protein using a chemical-inducible system in tobacco BY-2 cells

Researchers from the Japan Advanced Institute of Science and Technology (JAIST) and Ishikawa Prefectural University, Japan, recently attempted to synthesize the ORF8 protein with the help of a chemical-inducible protein production system using tobacco BY-2 cells. This study has been published demonstrated in the preprint server, bioRxiv.

SARS-CoV-2 survives on human skin for 9 hours

Japanese researchers have now studied the survival possibilities of the flu virus and the SARS-CoV-2 on human skin. Their study titled, "Survival of SARS-CoV-2 and influenza virus on the human skin: Importance of hand hygiene in COVID-19," was published in the latest issue of the journal Clinical Infectious Diseases.

Detection of SARS-CoV-2 viral persistence in built environments

In a recent paper in an open-access journal, mSystems, published by The American Society for Microbiology, Ceth W. Parker et al. show challenges in recovering the virus, change in infectivity, and the case of viral persistence in built environments.

Scientists refine SARS-CoV-2 protein structures

An international team of scientists has developed computational models to re-analyze and validate experimentally-derived publicly available macromolecular structures of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Face masks far more protective against COVID-19 than face shields, CDC experts

Researchers from the Centers for Disease Control and Prevention (CDC) have conducted a study showing that face masks and neck gaiters appear to be much more effective than face shields at reducing the expulsion of respiratory aerosols that could potentially transmit severe acute respiratory syndrome 2 (SARS-CoV-2).

Neutralizing responses to infection relatively common in COVID-19

A new study has shown that severe coronavirus disease 2019 (COVID-19) is associated with unique B cell receptor (BCR) signatures and multiclonal neutralizing responses against the causative agent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Researchers identify a promising method to stop COVID-19 infection

While the world waits eagerly for a safe and effective vaccine to prevent infections from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus behind the COVID-19 pandemic, researchers also are focusing on better understanding how SARS-CoV-2 attacks the body in the search for other means of stopping its devastating impact.

Study estimates lower herd immunity to SARS-CoV-2 in the U.S.

A new study shows that recognizing the differences in the population composition, connectedness and distribution, as well as inter-individual differences in immunity, susceptibility and infectivity, are crucial to estimating the herd immunity attained as a result of natural severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) more accurately.

Experimental Chinese SARS-CoV-2 vaccine appears safe in early trials

A new study published on the preprint server medRxiv in October 2020 reports the findings of a phase I trial of an inactivated SARS-CoV-2 vaccine, demonstrating that it can elicit a potent immune response without significant adverse reactions.
