SARS-CoV-2 mutations dictate severity of COVID-19 disease

A recent study by researchers from Semmelweis University and Pazmany Peter Catholic University in Budapest, Hungary, published on the preprint server medRxiv in October 2020, shows the relationship of specific mutations on the disease's outcome.

COVID-19 containment measures affecting other seasonal respiratory viruses

A recent study published on the preprint server medRxiv* in October 2020 indicates that so far, the containment measures put in place to prevent the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have effectively prevented the transmission of many other respiratory viruses.

Brain metabolic changes associated with loss of smell in COVID-19

A recent study detailed in a preprint paper published in medRxiv, researchers from Belgium, discuss how they investigated possible central nervous system (CNS) involvement in COVID-19 patients with a sudden loss of smell using a hybrid positron emission tomography (PET)-magnetic resonance imaging (MRI) system (PET-MR).

Dietary supplement represents an innovative strategy to help in the fight against SARS-CoV-2

SPIN (SPermidin and eugenol INtegrator for contrasting incidence of coronavirus in EU population) is a European project powered by EIT Food that is currently developing a dietary supplement supporting the function of the immune system in the fight against SARS-CoV-2 infections in population at high risk.

SARS-CoV-2 mutations possibly making virus less virulent

In their bioRxiv* preprint paper, the researchers focus on mapping the clade-specific mutations' effects on the protein structures' conformation and stability. They identified the mutations in the set of seven proteins - orf8, nsp2, nsp4, nsp6, nucleocapsid protein (N), and Spike protein (S).

New research projects to focus on drone-based medical deliveries

Cranfield University is participating in two new research projects that focus on the use of unmanned aerial vehicles (UAVs) for medical delivery purposes.

"Immunological imprinting" could influence antibody response to COVID-19

Researchers in the United States and Spain have shown that prior exposure to seasonal coronaviruses may influence antibody responses to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the causative agent of coronavirus disease 2019 (COVID-19).

Trump says he saved 2 million lives from COVID. Really?

President Donald Trump has repeatedly claimed to have saved 2 million lives from COVID-19 through his actions to combat the disease.

More than 2.5 million person-years of life lost in US due to COVID-19

In a recently published study, researcher Stephen Elledge from Harvard Medical School has described converting the coronavirus disease (COVID-19) death toll from individual deaths to “person-years” lost in order to provide a more accurate picture of the pandemic’s toll on the population.

Spike protein of SARS-CoV-2 virus identifies and binds neuropilin-1 on human cells to infect them

Helping to explain what makes SARS-CoV-2 so capable of infecting human cells, researchers in two independent studies discovered that the virus's spike protein recognizes and binds a protein on the human cell surface called neuropilin-1.

Study indicates the relationship between SARS-CoV-2 viral infection and diabetes

It has recently been described that infection by some enteroviruses - a genus of viruses that commonly cause diseases of varying severity - could potentially trigger diabetes, although its direct effect 'in vivo' as well as its mechanism of action at the molecular level were unknown.

Researchers conduct review on viral shedding of SARS-CoV-2

A review of dozens of studies by researchers at Oregon Health & Science University and Oregon State University suggests that people may shed virus for prolonged periods, but those with mild or no symptoms may be infectious for no more than about 10 days.

SARS-CoV-2 hijacks mitochondria

An important phase of the viral protein translation relies on the mitochondrial translation machinery. Towards this goal, the molecular mechanism involved in the SARS-CoV-2 entry into human cells is studied by Zhenguo Cheng et al.

Study shows ssRNA encapsidation results in stabilization of the Ebola virus nucleocapsid

The Ebola virus causes a serious infection with a mortality rate between 50% and 90%. Nucleoproteins in the virus assemble into a helical arrangement and encapsulate a single stranded RNA genome, ssRNA, to form a rodlike complex known as a nucleocapsid, which is critical to the function of the virus.

Study shows SARS-CoV-2 uses a receptor to efficiently infect human cells

To efficiently infect human cells, SARS-CoV-2, the virus that causes COVID-19, is able to use a receptor called Neuropilin-1, which is very abundant in many human tissues including the respiratory tract, blood vessels and neurons.

Researchers use supercomputers to simulate the inner working of Ebola virus

As the world grapples with the coronavirus (COVID-19) pandemic, another virus has been raging again in the Democratic Republic of the Congo in recent months: Ebola.

Researchers explore SARS-CoV-2 at single cell resolution in human airway epithelial cells

The cellular tropism of the SARS-CoV-2 virus affects several aspects of infection, such as the spread of the virus within and between hosts, tissue pathology, immune control mechanisms, and the response to treatment with promising antiviral drugs.

CDC says 'mask up' when traveling

These updates focus on the prevention of the spread of the infection during travel. Since the onset of the pandemic, international and intra-state travel has been restricted across many nations.

Researchers explore effect of temperature on molecular structure of SARS-CoV-2 spike

Didac Martí et al., from the Polytechnic University of Catalonia, in a recent bioRxiv preprint research paper, explore the effect of the temperature on the molecular structure of the SARS-CoV-2 spike glycoprotein. The study specifically focuses on the spike glycoprotein's molecular structural integrity at different temperatures (within 25 ºC and 100 ºC) using atomistic computer simulations.

3D imaging of SARS-CoV-2 infection in ferrets using light sheet microscopy

Researchers from the Friedrich-Loeffler-Institut, Federal Research Institute for Animal Health demonstrate the ability to detect severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in 3D tissue samples in ferrets. This will allow the detection of infection patterns in tissues and their interrelations.
