Bacterial movement is powered by tiny protein motor

The ability to move is key for bacteria like some strains of salmonella and E. coli to efficiently spread infections. They can propel themselves forward using threads, known as flagella, powered by the flagellar rotary motor.

Loss of taste in COVID-19 is highly variable by geographic region

Even as the COVID-19 pandemic spreads in different parts of the world, scientists are still attempting to define the characteristic signs and symptoms that are useful in diagnosing the disease. This is essential knowledge to help contain severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission. Especially when it comes to diagnosing symptomatic or mild cases of COVID-19, such research could hold the key to identifying more people and preventing viral spread.

New x-ray microscopy technique could help accelerate efforts to map neural circuits

One of the grand quests in neuroscience is to build a precise map of the brain, charting all its neurons and the connections between them. Such a wiring diagram, called a connectome, promises to help shed light on how a collection of cells can together give rise to thoughts, memories, behaviors and myriad other functions.

Tiny antibody component shows high potency in SARS-CoV-2 animal models

University of Pittsburgh School of Medicine scientists have isolated the smallest biological molecule to date that completely and specifically neutralizes the SARS-CoV-2 virus, which is the cause of COVID-19.

Circadian rhythm affects SARS-CoV-2 infection and host immune response

In an interesting bioRxiv preprint paper, French researchers show that the time day can affect infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as guide subsequent host immune response – implying that circadian rhythm may well be a novel target for managing viral progression.

Single-molecule imaging of SARS-CoV-2 spikes on virus particles

Using single-molecule FRET analysis, a team of researchers has revealed how the different conformations of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein are interconnected. Figuring out the different conformations in real-time and which conformations antibodies prefer may help design effective vaccines and drugs. The research is published on the preprint server bioRxiv*.

A map of SARS-CoV-2 escape mutations enables the development of therapeutic antibody cocktails

A recent tour-de-force study by the US researchers describes a comprehensive approach to completely map mutations to the SARS-CoV-2 receptor-binding domain (RBD) that escape antibody binding – enabling, in turn, rational design of antibody therapeutics and appraisal of the antigenic consequences of viral evolution. The results are currently available in a bioRxiv preprint paper.

India's whole-virion inactivated SARS-CoV-2 vaccine shows promise

Researchers in India have conducted a preclinical study demonstrating the safety and efficacy of a new candidate vaccine for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

Risk stratification tool for COVID-19 patients developed

Researchers have worked on the development of a protocol that could stratify COVID-19 patients based on a scoring system. This new study describing the scoring system for risk stratification is titled, “Risk stratification of patients admitted to hospital with covid-19 using the ISARIC WHO Clinical Characterisation Protocol: development and validation of the 4C Mortality Score,” and is published in the latest issue of the British Medical Journal.
