What are the dynamics of SARS-CoV-2 transmission inside an aircraft cabin?

A team of US scientists has recently evaluated the risk of SARS-CoV-2 infection among passengers present inside an aircraft cabin. The findings suggest that the risk of airborne viral transmission is minimal during long-duration flights.

Scientists identify animal model to study human musculoskeletal aging

There are many components to aging, both mental and physical. When it comes to the infrastructure of the human body - the musculoskeletal system that includes muscles, bones, tendons and cartilage - age-associated decline is inevitable, and the rate of that decline increases the older we get.

New tests may help reveal the transcriptome of SARS-CoV-2 and predict disease course

As the COVID-19 pandemic continues to infect people in their hundreds of thousands around the world, a new study describes a panel of novel tests for genomic (g) and subgenomic (sg) mRNAs generated by SARS-CoV-2. Most assays in use at present are either qualitative or semi-quantitative, and cannot evaluate the transcription molecules in detail.

A snake venom enzyme shows anti-SARS-CoV-2 activity in vitro

A new study reports the virucidal and fusion-inhibiting attributes of snake venom against the COVID-19 agent SARS-CoV-2.

No inflammation of cerebrospinal fluid in COVID-19 patients with neurological features, study finds

Many patients with COVID-19 have shown neurological complications, leading to scientific interest in the role played by its causative pathogen, SARS-CoV-2, in brain inflammation. A new study has described the absence of neuroinflammation in cerebrospinal fluid (CSF).

Researchers demonstrate great potential for blood test to detect, monitor Alzheimer's disease

In three recent publications in Molecular Psychiatry, Brain and JAMA Neurology researchers from the University of Gothenburg provide convincing evidence that an in-house developed blood test for Alzheimer's disease can detect the disease early and track its course, which has major implications for a potential use in clinical practice and treatment trials.

MVA SARS-CoV-2 vaccine candidate shows strong immunogenicity in preclinical trials

A new study reports the preclinical testing of a recombinant MVA (rMVA) candidate vaccine against SARS-CoV-2, the agent that is causing the current COVID-19 pandemic.

Could intranasal SARS-CoV-2 vaccines be a practical alternative to intramuscular shots?

The unchecked advance of COVID-19 has made it a top public health priority to produce a vaccine capable of inducing a safe and powerful protective response against its causative pathogen: SARS-CoV-2. An encouraging new study shows the immunogenicity, safety, and protective efficacy, of a Newcastle disease virus (NDV)-based intranasal vector vaccine in animal studies.

Researchers develop a tiny, yet effective method for preventing premature birth

In a study in mice and human cells, Johns Hopkins Medicine researchers say that they have developed a tiny, yet effective method for preventing premature birth.

Study reveals cardiac protein as a new target for different types of heart disease

Like a failing fuel pump that causes a loss of engine power in a car, a diseased heart can take a serious toll on the body's performance. For some patients, tasks like walking up a flight of stairs or walking across a room eventually turn into exhausting endeavors.

Scientists identify key enzyme as driver of autoimmune blistering diseases

The Granzyme B (GzmB) enzyme, which accumulates in certain tissues as we age, has been identified as a driver of itchy and sometimes life-threatening autoimmune conditions known as pemphigoid diseases (PDs), which cause blistering and skin erosion below the skin's surface.

How has the UK-derived SARS-CoV-2 mutant strain spread internationally?

Researchers analyzed Facebook-based mobility data and found that travelers from UK may have spread the new SARS-CoV-2 strain that originated in the UK to at least 16 countries by the beginning of December 2020.

Moderna to develop three new mRNA-based vaccines against HIV, influenza, and the Nipah virus

Morderna has announced plans to develop a range of new mRNA-based vaccines against other viruses, including the influenza virus, human immunodeficiency virus (HIV), and the Nipah virus.

Researchers map genetic changes that may have facilitated SARS-CoV-2’s jump from bats to humans

Researchers from the University of Cambridge and the Pirbright Institute in the UK have identified key genetic changes in SARS-CoV-2 that may be responsible for the virus’s jump from bats to humans. The team also determined which animals contain cellular receptors that allow the virus to enter cells more effectively, zoning in on potential animals that acted as an intermediary host in facilitating SARS-CoV-2’s zoonosis.
