SARS-CoV-2 viral load predicts risk of death

As the coronavirus pandemic evolved, there have been many developments in testing for the SARS-CoV-2 viral load in patients. Now, a team of researchers at the Icahn School of Medicine at Mount Sinai, New York, has found that the SARS-CoV-2 viral load can predict mortality in patients with coronavirus disease (COVID-19).

C-type lectin receptors play a role in SARS-CoV-2 infection

A new study published on the preprint server bioRxiv in August 2020 confirms and extends earlier findings showing that a type of sugar-based receptor on innate immune cells promotes the entry of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into other cells that carry the viral receptor, angiotensin-converting enzyme 2 (ACE2).

SARS-CoV-2 a "swarm" of mutant viruses

In this new study, the virus was serially passaged in independent cell types in a controlled environment. The researchers found that the virus rapidly adapts to the changing conditions in culture by selecting for pre-existing species.

Can SARS-CoV-2 be transmitted via feces?

A new study by researchers at the University of Oxford and the Trip Medical Database and published on the preprint server medRxiv* in August 2020 as part of the ongoing Open Evidence Review on Transmission Dynamics of COVID-19 reports the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in feces and the need for precautions to prevent orofecal spread in the surroundings of confirmed or suspected cases.

Researchers reveal molecular workings of a key system in learning and memory formation

One of the new realities in biomedical research is that it's increasingly difficult to use a general approach to score advances. Now, investigations into disease mechanisms, for example, are often conducted at the molecular level by specialists who dedicate years to interrogating a single protein or signaling pathway.

Finned nanoporous catalyst facilitates molecular transport

Thousands of chemical processes used by the energy industry and for other applications rely on the high speed of catalytic reactions, but molecules frequently are hindered by molecular traffic jams that slow them down.

A magnetic-sensitive artificial catalyst can remotely control chemical reactions inside living cells

The enzymes responsible for catalytic reactions in our body's biological reactions are difficult to use for diagnosis or treatment as they react only to certain molecules or have low stability.

Vaccine 'nationalism' will slow coronavirus fight if poor countries are left exposed

As the coronavirus vaccine race charges on, many of the investigational candidate vaccines are nearing the final stages of human trials. The results of these trials will determine if they will be granted the green light to manufacture and distribute the vaccine to countries across the globe.

COVID-19 patient with repeatedly undetectable SARS-CoV-2 antibodies

A recent case study published in the Journal of Applied Laboratory Medicine in August 2020 illustrates this with its finding of persistent seronegativity in a patient confirmed to be SARS-CoV-2 positive.

Speed of Novavax vaccine development does not compromise quality of the SARS-CoV-2 immunogen

A new study by researchers from the Scripps Research Institute and Novavax Inc. in the US affirms the structural integrity of the full-length SARS-CoV-2 spike glycoprotein immunogen. It enables the interpretation of immune responses to this multivalent nanoparticle immunogen. Their results are currently available on bioRxiv preprint server.

Characteristics of electron emission from irradiated biomolecules

When fast-moving ions cross paths with large biomolecules, the resulting collisions produce many low-energy electrons which can go on to ionise the molecules even further. To fully understand how biological structures are affected by this radiation, it is important for physicists to measure how electrons are scattered during collisions.
