Modeling the spread and development of SARS-CoV-2 outbreaks in the US

In a research paper recently uploaded to the medRxiv* preprint server, high-resolution contact data is utilized to characterize severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission in the USA, considering infections' mobility and seasonality and vaccination status seroprevalence within the population.

Direct evidence in hamsters shows SARS-CoV-2 is airborne

Evidence suggests that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be transmitted without contact by respiratory droplets and aerosols bearing the virus when coughing, sneezing, speaking, and breathing. The virus has been cultured from aerosols collected nearby COVID-19 patients, and such aerosols can linger in still air for hours.

COVID-19 prevention strategies for the U.S. food industry

A new study discusses the measures that should be taken to mitigate the risk of COVID-19 among food industry workers.

Certain intestinal bacteria induce cross-reactive IgA responses to the SARS-CoV-2 spike RBD

A new study finds that human gut bacteria can induce antibodies of the immunoglobulin A (IgA) subtype that cross-react with the SARS-CoV-2 spike RBD.

Discovery of highly potent neutralizing monoclonal antibodies against SARS-CoV-2

A new study published in the journal Nature Communications has reported two neutralizing antibodies, namely, nCoVmab1 and nCoVmab2, which are potent against SARS-CoV-2.

How replication and recombination contribute to emergence of SARS-CoV-2 variants

The coronavirus disease 2019 (COVID-19) pandemic has been caused by the rapid outbreak of a novel coronavirus, namely, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). SARS-CoV-2 was first reported in late December 2019 in Wuhan, China. Since then, the virus has already claimed more than 4.3 million lives worldwide.

Research debunks myth that COVID vaccination promotes mutations

A study conducted by researchers at the University of Maryland, USA, has highlighted the importance of coronavirus disease 2019 (COVID-19) vaccination in reducing the frequency of mutations in the delta variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

SARS-CoV-2 variants containing L452R spike mutation more resistant to antibody-mediated neutralization

A team of scientists from Frankfurt, Germany, has recently explored the efficacy of vaccine- or infection-induced antibodies and therapeutic monoclonal antibodies in neutralizing kappa and delta variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Camelid nanobody anti-SARS-CoV-2 drug candidates

In a research paper recently published in the journal eLife, researchers from several US institutions have developed a nanobody-based candidate drug that effectively prevents and suppresses severe SARS-CoV-2 infection in animals.

Optical nanoscopy reveals how SARS-CoV-2 infection alters human airway cells

How do viruses reorganize host cells with spatial and molecular specificity? Researchers from the Netherlands provided new insights in a recent study posted to the bioRxiv* preprint server, where they use optical nanoscopy to look at severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-triggered changes in primary human airway cells.

SARS-CoV-2 detection by machine learning surface-enhanced Raman spectroscopy

Surface-enhanced Raman spectroscopy is a highly sensitive molecule characterization method, significantly more sensitive than ordinary Raman spectroscopy due to the excitation of Raman modes matching the plasmon resonance frequency of the surface metal utilized, usually gold, silver, or copper.

VPS29 gene facilitates coronavirus cell entry

In a research paper recently uploaded to the bioRxiv* preprint server by Poston et al. (August 8th, 2021), common host factors amongst several zoonotic pathogens are explored by CRISPR-Cas9 screening in human lung cells, focusing in particular on the betacoronavirus genus.
