Researchers use molecular dynamics simulations to identify secrets of SARS-CoV-2 virus

The virus wreaking havoc on our lives is an efficient infection machine. Comprised of only 29 proteins (compared to our 400,000), with a genome 1/200,000 the size of ours, SARS-CoV-2 is expertly evolved to trick our cells to contribute its machinery to assist in its propagation.

Comparative analysis reveals common vulnerabilities across coronaviruses

Three lethal human respiratory syndromes associated with coronavirus (CoV) infections have emerged in the past two decades. They are severe acute respiratory syndrome (SARS) in 2002, Middle East respiratory syndrome (MERS) in 2012, and coronavirus disease 2019 (COVID-19) in 2019.

D614G mutation in SARS-CoV-2 increases viral fitness and infectivity

Researchers from the Duke Human Vaccine Institute and Duke University, Durham NC, USA, recently analyzed the D614G mutation in SARS-CoV-2 in the context of a soluble S ectodomain construct. Their study has been published in the preprint server bioRxiv.

Genoscience Pharma's GNS561 shows potential against SARS-CoV-2 in vitro

A new study published on the preprint server bioRxiv in October 2020 shows that a combination of a new compound GNS561 and remdesivir act synergistically against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This suggests that autophagy inhibitors could be an alternative strategy for SARS-CoV-2 infection.

Development of a coarse-grained model of SARS-CoV-2 virion

A team of scientists of the University of Chicago and the University of California San Diego has developed a coarse-grained (CG) model of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virion. The model can be used as a valuable resource to perform multiscale simulations of the SARS-CoV-2 virion. The study is currently available on the bioRxiv* preprint server.

Observation offers a better understanding of how neurons communicate with each other

The dialogue between neurons is of critical importance for all nervous system activities, from breathing to sensing, thinking to running. Yet neuronal communication is so fast, and at such a small scale, that it is exceedingly difficult to explain precisely how it occurs.
