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.

CDC's mask guidance may have increased the threat of COVID-19 among vulnerable communities

The Centers for Disease Control and Prevention may have increased the threat of COVID-19 infection in the Black community and among some other racial and ethnic minority groups when the agency updated its mask guidance last May, according to a new commentary in the Journal of General Internal Medicine by two colleagues at Massachusetts General Hospital.

South Australian-developed SARS-CoV-2 vaccine shows promise to prevent COVID-19 lung infection

A South Australian-developed SARS-CoV-19 vaccine is preparing to progress to the final stages of human clinical trials after early animal testing confirmed its safety and effectiveness in preventing COVID-19 lung infection.

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.

COVID-19 risks likely to shift from older adults to younger children

Within the next few years, as the SARS-CoV-2 virus becomes endemic in the global population, COVID-19 may behave like other common-cold coronaviruses, affecting mostly young children who have not yet been vaccinated or exposed to the virus, according to new modeling results.

Norwegian study on the benefits of COVID vaccination for residents and employees in nursing homes

It is important to understand the vaccine effectiveness (VE) to determine how much protection it offers to the general population. Unfortunately, only a few studies are available that have determined the effect of the COVID-19 vaccine among the residents of LTCFs.
