Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

Researchers develop ultrapotent miniproteins that target SARS-CoV-2 receptor-binding domain

Researchers have investigated the effectiveness of a bioengineered miniprotein in protecting against SARS-CoV-2 infection in vivo. The researchers evaluated the miniprotein, LCB1, against SARS-CoV-2-mediated lung disease in human ACE2-expressing transgenic mice.

Quantifying SARS-CoV-2 viral load in hospitalized patients

A new paper, published on the medRxiv preprint server, investigates the role of subgenomic RNA transcripts in SARS-CoV-2 infection. Earlier, scientists believed that subgenomic RNA could be traceable infective markers to monitor infectivity.

Coronavirus-like nanoparticles could serve as a positive control for COVID-19 tests

Rapid COVID-19 tests are on the rise to deliver results faster to more people, and scientists need an easy, foolproof way to know that these tests work correctly and the results can be trusted. Nanoparticles that pass detection as the novel coronavirus could be just the ticket.

A simple blood draw may help discover tumor reactive immune cells to treat advanced melanoma

According to a new study led by Yale Cancer Center and Department of Neurology researchers, a simple blood draw may be the first step in helping to discover tumor reactive immune or T cells to treat advanced melanoma, a deadly form of skin cancer.

Researchers develop a genetic patch to prevent hereditary deafness

They can hear well up to about forty years old, but then suddenly deafness strikes people with DFNA9. The cells of the inner ear can no longer reverse the damage caused by a genetic defect in their DNA.

SARS-CoV-2 UK variant shows low virulence and high shedding in hamster model

A new study compares the pathogenicity and infectiousness of one such variant, the VOC 202012/01 (B.1.1.7 lineage) from the United Kingdom, with the globally dominant D614G mutation-carrying strains.

Graphene oxide-silver nanoparticles shown to rapidly neutralize RNA viruses

While the vaccines against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are administered, and extensive research is conducted for targeted therapeutics to control the COVID-19 (coronavirus disease 2019), it is equally crucial to develop more novel, broad-spectrum antiviral compounds.

Unique nanoparticles can package and deliver gene-editing machinery to the liver

The genome editing technology CRISPR has emerged as a powerful new tool that can change the way we treat disease. The challenge when altering the genetics of our cells, however, is how to do it safely, effectively, and specifically targeted to the gene, tissue and organ that needs treatment.

Study shows asthma mediator IL-13 prevents SARS-CoV-2 infection

In a paper published on the bioRxiv preprint server, researchers reported the results on whether IL-13 expression in asthma patients reduces their susceptibility to SARS-CoV-2 infection.

Scientists establish infection models for SARS-CoV-2 UK & South African variants

New research suggests Syrian golden hamsters could be a potentially useful preclinical model for testing vaccine immunity against the acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.17 and B.1.351 variant.

New technique uncovers the tricks used by cancer cells to evade immunotherapies

By harnessing the immune system against cancer, immunotherapies have revolutionized the way some types of cancer are treated. But most patients--across cancer types--do not respond, and in most cases, scientists are at a loss as to why.

Comparative analysis of SARS-CoV-2 antivirals leads to new potential treatment for COVID-19

Scientists compared the in vitro efficacy and cytotoxicity profiles of PF-00835231 and remdesivir in two human model systems for SARS-CoV-2 infection.
