Human-to-cat transmission of SARS-CoV-2 confirmed

Cat-to-cat transmission of SARS-CoV-2 has been experimentally proven, but little is known about the significance of this novel virus as a feline pathogen or its reverse zoonotic potential. The establishment of new animal reservoirs of SARS-CoV-2 could pose serious problems for human health in the future.

A possible inverse relationship between Dengue and COVID-19 in Brazil

Their study titled, “How super-spreader cities, highways, hospital bed availability, and dengue fever influenced the COVID-19 epidemic in Brazil,” was released pre-peer review on the preprint medRxiv* early this week.

Experimental cancer drug AR-12 inhibits SARS-CoV-2 virus

Nine months into the global pandemic, which has infected more than 32 million people, there is still no approved effective and safe drug or vaccine against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Linoleic acid binds SARS-CoV-2 spike protein

Now, a team of researchers at the Max Planck-Bristol Center for Minimal Biology and Bristol's School of Biochemistry has identified a druggable pocket in the virus's spike protein that can be used to prevent the infection of cells. The study findings, published in the journal Science, are a groundbreaking discovery that will help develop new therapies and drugs to stem the growing pandemic.

School re-openings in US may increase COVID-19 spread unless targeted interventions are in place

In a new study published on the preprint server medRxiv, a team of researchers on behalf of the Imperial College London COVID-19 Response Team used longitudinal and age-specific population mobility and COVID-19 mortality data to model and predict SARS-CoV-2 spread in the US.

Cold plasma inactivates SARS-CoV-2

In one such effort, Zhitong Chen et al., in a recent medRxiv* preprint paper find that by employing an efficient cold atmospheric plasma (CAP) with argon feed gas on different surfaces inactivates the infectious SARS-CoV-2 virus.

Researchers solve the mystery of how giant molecular proton pump works

Mitochondria are the powerhouses of our cells, generating energy that supports life. A giant molecular proton pump, called complex I, is crucial: It sets in motion a chain of reactions, creating a proton gradient that powers the generation of ATP, the cell's fuel.

Prevalence of SARS-CoV-2 with D614G mutation in a second wave infection in Houston

A recent study reveals that the genetic variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) detected in the initial phase of coronavirus disease 2019 (COVID-19) pandemic differ from the variants detected in a massive second wave of infection in Houston, Texas. The study is currently available on the medRxiv preprint server.

Ethnic minority groups disproportionally affected by COVID-19

The study, which assessed the clinical records of more than 17 million adults, also identified inequalities in the risk of needing admission to ICU and the risk of COVID-19-related death.

Tokyo citizens may have developed COVID-19 herd immunity, say researchers

Researchers in Japan and the United States have conducted a study showing that herd immunity to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may have developed among the citizens of Tokyo during the summer.

As fires and floods wreak havoc on health, new climate center seeks solutions

For the past month, record-breaking wildfires have torched millions of acres from the Mexican border well into Canada, their smoke producing air so toxic that millions of people remained indoors for days on end while many visited hospitals because of respiratory distress.

Automated computational protocol identifies potential SARS-CoV-2 MPro inhibitor

As scientists race to discover new and effective antiviral drugs against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), many novel approaches are being utilized. Now, a new study published on the preprint bioRxiv in September 2020 reports on the discovery of a potentially beneficial enzyme blocker that could inhibit SARS-CoV-2 viral replication.

AI used to define the cytokine storm implicated in fatal COVID-19

A new study published on the preprint server bioRxiv* in September 2020 reports the use of artificial intelligence (AI) to identify an invariant or universal host immune response found in all viral pandemics so far. The association of this response with severe COVID-19 phenotypes indicates a new understanding of the human immune response in viral pandemics.

Research says in SARS-CoV-2 canine infection, transmission unlikely

A new study published on the preprint server bioRxiv* in September 2020 shows that pet dogs have been falling sick and dying of a mysterious respiratory infection, often showing the presence of anti- severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies, even though in many cases they do not test positive for COVID-19.

Aerosol-based study of COVID-19 risk indoors, and the impact of preventive measures

A recent study describes the estimated risk of COVID-19 transmission via aerosols in many different situations, as well as the expected reduction in risk associated with the use of various preventive measures.

NeutrobodyPlex nanobodies help monitor SARS-CoV-2 immune responses

Researchers recently described a set of 11 Nbs derived from an immunized alpaca which showed high-affinity binding to the glycosylated SARS-CoV-2 spike receptor domain (RBD) in a study published in the preprint server bioRxiv.

New tool helps to find out toxins lurking in drinking water

Exposure to hydraulic fracturing fluid in drinking water has been shown to increase the risk of respiratory problems, premature births, congenital heart defects, and other medical problems. But not all wells are created equal.

Most people with COVID-19 develop symptoms, study says

A new study by researchers at the University of Bern and published in the journal PLOS Medicine reports that while some people never experience any symptoms, most of those infected with the novel coronavirus do develop symptoms.

Elegant, efficient way to find recombinant SARS-CoV-2 viruses from >85,000 genomes

The low divergence of near-identical genomes that are sequenced in short periods presents a statistical challenge that is not addressed by methods available currently. In a recent bioRxiv** paper, Ales Varabyou et al. from John Hopkins University present an efficient method designed to detect recombination and reassortment events between clades of viral genomes – a new algorithm called ‘Bolotie’.

How families are keeping Halloween from turning into a COVID nightmare

For Laura Stoutingburg and her family, Halloween has always been a monthlong celebration of corn mazes, pumpkin patches and, of course, trick-or-treating in their suburban Denver neighborhood.
