Nanoparticle SARS-CoV-2 model could potentially speed the search for drugs

A team of scientists from the National Center for Advancing Translational Sciences and Naval Research Laboratory in Washington, D.C., has developed a new tool that mimics how SARS-CoV-2 -- the virus that causes COVID-19 -- infects a cell, information that could potentially speed the search for treatments against the disease.

SARS-CoV-2 infects monocytes and macrophages, without cytopathic effect

A team of researchers from Aix-Marseille Univ, IHU-Méditerranée Infection, Institut Paoli Calmettes and Laboratoire d’Immunologie, Marseille, France, conducted experiments to determine if SARS-CoV-2 can affect the myeloid compartment or infect monocytes and macrophages.

Research provides deeper understanding of how neurons in the nose react to odors

Take a sniff of a freshly poured glass of wine, and the prevailing scientific thinking would suggest that the harmony of fragrances you perceive starts with sensory receptors in your nose simply adding up the individual odors they encounter.

Newly identified mechanism regulates the distensibility of the heart

A healthy heart beats 50 to 100 times a minute and pumps 8,000 litres of blood around our body every day. A precondition for this function is the elasticity of the cardiac walls, which dilate as blood flows in (diastole) and contract again as the blood flows out (systole).

New antibody assay for COVID-19 promises sensitive mass-scale detection

A new paper by researchers at McMaster University and Hamilton Health Sciences, published on the preprint server medRxiv in September 2020, reports on the development of a serologic assay that is suitable for sensitive high-throughput antibody testing for COVID-19.

Buckling could trigger embryo morphogenesis

The embryo of an animal first looks like a hollow sphere. Invaginations then appear at different stages of development, which will give rise to the body's structures (the brain, digestive tract, etc.).

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*.

SARS-CoV-2 does not pose a food safety risk, health agency says

Now, a new report by the International Commission on Microbiological Specifications for Foods (ICMSF) highlights the link between SARS-CoV-2 infection and food safety. ICMSF is a global non-government organization that aims to provide information on food safety and human health.

Brazilian state of Maranhão heading towards SARS-CoV-2 herd immunity, say researchers

Researchers at the Federal University of Maranhão, Brazil, have conducted a study suggesting that the state of Maranhão is well on its way to acquiring herd immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

World's first confirmed case of SARS-CoV-2 re-infection

A team of researchers at the University of Hong Kong said that they have proven that a 33-year-old man was infected by the SARS-CoV-2 virus for a second time. The man was discharged from a hospital in April but contracted the infection again after returning from Spain via the United Kingdom in August.
