Does climate play a large role in SARS-CoV-2 transmission?

A team of researchers from the Universidade Federal de Itajuba in Brazil has reported that weather plays a vital role in determining the transmission rate of SARS-CoV-2 infection.

How does the SARS-CoV-2 E484K mutation increase viral fitness?

How do mutations benefit SARS-CoV-2? To explore this, a team of researchers from China took a closer look at the physical interactions that occur between the proteins after viral mutation.

USDA, FDA highlight no credible evidence of COVID-19 transmission through food or food packaging

After more than a year since the coronavirus disease 2019 (COVID-19) outbreak was declared a global health emergency, the U.S. Department of Agriculture, the U.S. Food and Drug Administration and the U.S. Centers for Disease Control and Prevention continue to underscore that there is no credible evidence of food or food packaging associated with or as a likely source of viral transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the virus causing COVID-19.

Changes in drinking and smoking during England’s first COVID-19 lockdown

The worldwide spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 infection in early 2020 prompted many nations to close their borders and institute mandatory lockdowns. While lockdowns abruptly stopped daily life, researchers from the University College London and the University of Sheffield found drug-seeking behaviors did not.

O-glycosylation of SARS-CoV-2 spike protein in insect and human cell lines

The mapping of O-glycosites requires instruments that can support electron transfer dissociation (ETD) fragmentation. In a new study published on the bioRxiv preprint server, researchers report their results on whether O-glycosylation patterns affect immunogens for vaccine development.

How has 3D printing come to the aid of healthcare during the COVID-19 pandemic?

In the study, published in the journal Emergent Materials, the researchers identified the role of 3D printing in COVID-19. During the pandemic, over 100 various 3D printable PPE designs have been used.

A glycan controls how SARS-CoV-2’s spike protein opens, study finds

Using simulations, a team of researchers in the U.S. found that the glycan at position N343 of the SARS-CoV-2 spike protein’s receptor-binding domain (RBD) helps in its opening. A mechanism that aids its binding to the host cell receptor.

Endothelial SARS-CoV-2 infection induces proinflammatory responses without supporting viral amplification, finds study

A team of scientists from Australia and Brazil recently investigated the involvement of endothelial cells in the pathogenesis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

SARS-CoV-2 D614G mutation associated with lower antibody binding

The onset of the COVID-19 pandemic has brought about an international effort to uncover the biology of its causative agent, SARS-CoV-2, and to develop effective and safe antivirals to contain and treat the infection. A new study by a team of researchers in France and Sweden discusses one such study, exploring the relative immunogenicity of the three main structural proteins of the virus.

How have COVID-19 pandemic school closures impacted the health of children globally?

A new study by researchers in the US and the UK explores the damage caused by school closures to educational progress, health, and well-being in children and young people globally.

SARS-CoV-2 variants of concern drive up infections by 15-40 percent in Germany

As the coronavirus disease 2019 (COVID-19) pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continues to distress worldwide, new variants are emerging that threaten the possibility of containment by current vaccines or therapeutic antibodies.

CDC study says face mask mandates reduced COVID-19 hospitalizations in the U.S.

A new study by researchers at the CDC examined whether the implementation of the mask mandate is tied to COVID-19-related hospitalization growth rates among different age groups.

Advancements in DNA vaccines against COVID-19

The rapid spread of the pathogen and the increasing number of cases highlight the need for an effective and safe vaccine. As vaccination efforts roll out in many countries, new types of vaccines, like deoxyribonucleic acid (DNA) vaccines, are under research..

Convalescent plasma shows CD8+ T cell responses to SARS-CoV-2 variants

Researchers in the United States have conducted a study suggesting that individuals who have recovered from or been vaccinated against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) should maintain effective CD8+ T-cell responses against the major variants that have recently emerged.

17 Feb 2021

Where might future novel coronaviruses come from?

The researchers predicted many more associations between coronaviruses and host species than have been observed to date. They also predicted 30 times more potential recombination hosts of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

Purely mathematical perspective on delaying the second dose of the SARS-CoV-2 vaccine

High demand for the vaccines has raised questions as to whether it would be better in the long term to ensure that as much of the population as possible has received the first dose, i.e., vaccinate twice as many people with a lower rate of efficacy.
