Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

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.

Single dose nasal vaccine against SARS-CoV-2 shows promise in animal studies

Now researchers at the Washington University School of Medicine in St. Louis have worked on developing a candidate vaccine against the infection that could be administered in a single dose via a nasal spray rather than an injection. In their preliminary studies using lab mice, this single dose of the nasal vaccine successfully prevented the infection with the novel coronavirus.

RNA-targeting compound restarts a healing factor silenced by heart attack

A heart attack can leave parts of the heart permanently scarred and stiff, resulting in prolonged disability and potential progression toward heart failure. Scientists have studied various ways to repair or regenerate such damaged heart tissue, with limited success.

Assessment of SARS-CoV-2 transmission on an airplane

As the COVID-19 pandemic continues to spread across the world, air travel restrictions are slowly being eased in some regions. Now, a new report published in the JAMA Network Open journal in August 2020 shows that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can spread among passengers on international flights unless proper precautions are taken.

Pfizer/BioNTech COVID-19 vaccine candidate BNT162b2 profiled for large scale clinical trials

Although two RNA-based severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine candidates elicited similar, dose-dependent neutralizing antibody titers in both younger and older adults, a recent study by researchers from the U.S. and Germany has shown that BNT162b2 is associated with less systemic reactogenicity in elderly individuals – supporting its selection for further phase 2/3 clinical trials. The study is currently available on medRxiv* preprint server.

Raccoon dogs potential intermediate host for SARS-CoV-2

Researchers at the Friedrich Loeffler Institute in Germany have conducted a study demonstrating that raccoon dogs were a potential intermediate host in the transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19).

New COVID-19 pooling test detects asymptomatic carriers

A new peer-reviewed study published in Science Advances confirms the success of a new COVID-19 pooling test that identifies all positive subjects, including asymptomatic carriers, in a single round of testing.

DNA nanoswitches may provide an inexpensive platform to rapidly detect emerging viruses

Programmable DNA nanoswitches that bind to viral RNA in human body fluids may provide an inexpensive platform to rapidly detect a wide variety of emerging viruses, including SARS-CoV-2, according to a new study.

Harvard's Wyss Institute launches Torus Biosystems to develop, commercialize DNA nanotechnology

The Wyss Institute for Biologically Inspired Engineering at Harvard University announced today that Cambridge, MA-based Torus BiosystemsTM, Inc., will develop and commercialize DNA nanotechnology developed at the Wyss Institute by Peng Yin and David Zhang.

Bioinformatics identifies key genes and cellular pathways in COVID-19

The COVID-19 pandemic is showing no signs of waning or extinction anytime soon. Now, a new study published on the preprint server bioRxiv* in August 2020 shows a new bioinformatics approach to studying the pathogenesis of this disease, by uncovering the differentially expressed genes (DEGs) and cell signaling pathways that cause the disease characteristics. This will help develop better therapies to counter the effects of these genes.

No evidence of active SARS-CoV-2 in breastmilk of infected women

A recent study published in the journal JAMA in August 2020 suggests that SARS-CoV-2 RNA does not represent replication-competent virus and that breast milk may not be a source of infection for infants.

Combining expertise in organoids and sequencing technologies for ALS research

MDC researchers received a $150,000 pilot project grant from the Chan Zuckerberg Initiative's Neurodegeneration Challenge Network to investigate a defining feature of amyotrophic lateral sclerosis (ALS).

Study evaluates the reliability of new serological assays for detecting SARS-CoV-2 antibodies

Approximately four months after the initial description of cases of atypical pneumonia in Wuhan, China, in December 2019, COVID-19 had become a major pandemic threat.

Breast milk is not a potential source of infection, indicates study

As the novel coronavirus continues to spread around the world, so do the concerns of breastfeeding mothers.Although there have been no documented cases to date of an infant contracting COVID-19 as a result of consuming infected breast milk, the critical question of whether there is potential for this form of transmission remains.
