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.

Study shows how CD4+ T cells respond to SARS-CoV-2 virus

As scientists around the world develop life-saving COVID-19 vaccines and therapies, many are still wondering exactly why the disease proves deadly in some people and mild in others.

Sofosbuvir combined with other antivirals is more effective against COVID-19, shows study

Columbia Engineering researchers report that Sofosbuvir-terminated RNA is more resistant to the proofreader of SARS-CoV-2, the virus that causes COVID-19, than Remdesivir-terminated RNA.

Antigen testing detects SARS-CoV-2 better than PCR

A team of scientists from the United States demonstrates that rapid antigen tests for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) are more effective in determining the actual infection status in patients with coronavirus disease 2019 (COVID-19) than real-time polymerase chain reaction (RT PCR)-based tests.

'Dipstick' technology could be used for mobile and accurate COVID-19 testing

Technology that helps to quickly extract and analyze genetic material could be used for cheap, accurate and mobile COVID-19 testing, including at airports and remote testing centres.

Easier-to-use coronavirus saliva tests start to catch on

As the coronavirus pandemic broke out across the country, health care providers and scientists relied on the standard method for detecting respiratory viruses: sticking a long swab deep into the nose to get a sample. The obstacles to implementing such testing on a mass scale quickly became clear.

Older heavier COVID-19 positives likely to be superspreaders

The spread of SARS-CoV-2 is known to be through respiratory droplets as well as via aerosols, composed of minute particles normally exhaled during natural breathing.

SARS-COV-2 traveled from China to West Africa directly or via Europe

With the onset of COVID-19, the focus of medical research has been on tracing the origin of SARS-CoV-2, which was first reported in China’s Wuhan city.

Chronic illnesses promote active SARS-CoV-2 infection via suppressed mucosal immunity

A recent paper published in the preprint server medRxiv in September 2020 discusses the “clinically relevant variation in the expression of COVID-19-related genes”, which is associated with the host and environmental factors, as well as host genetic factors.

Thiopurines could help stop viral replication in human coronaviruses

Researchers from the Department of Microbiology & Immunology, Dalhousie University, University of Calgary, and Department of Biochemistry and Molecular Biology, University of British Columbia, Canada, worked with human coronaviruses in cell cultures to look for drugs that might prevent accumulation and replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Development of a coarse-grained model of SARS-CoV-2 virion

A team of scientists of the University of Chicago and the University of California San Diego has developed a coarse-grained (CG) model of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virion. The model can be used as a valuable resource to perform multiscale simulations of the SARS-CoV-2 virion. The study is currently available on the bioRxiv* preprint server.

New findings could improve investigation of T cell response to COVID-19

Researchers in the United States have made an important discovery about the processing and presentation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral peptides that provides a better understanding of the immune response to coronavirus disease 2019 (COVID-19) and may help facilitate the design of improved vaccines.

Study fails to establish independent risk factors for SARS-COV-2 infection in HIV patients

As the COVID-19 pandemic continues to spread worldwide, a new study published in the International Journal of Infectious Diseases in September 2020 reports that people with HIV infection are not at greater risk of COVID-19 compared to the general population.

Advanced model reveals dynamic motions of SARS-COV-2 spike-shielding glycans

A recent paper published on the preprint server bioRxiv in September 2020 discusses the dynamic interactions of the spike protein glycan shield, which may be of great value in developing therapeutic compounds to fight severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Wyss Institute’s technologies licensed to Agile Biodetection to aid COVID-19 diagnostic efforts

The Wyss Institute for Biologically Inspired Engineering at Harvard University announced today that its nasopharyngeal swab and toehold switch technologies have been licensed to Alabama-based Agile Biodetection, which will use them to develop solutions for unmet diagnostic needs in the detection of the SARS-CoV-2 virus in environmental or clinical settings.

A new technology to diagnose COVID-19 in just 30 minutes

The year 2020 can be summarized simply by one word - COVID-19 - as it was the culprit that froze the entire world. For more than 8 months so far, movement between nations has been paralyzed all because there are no means to prevent or treat the virus and the diagnosis takes long.
