SARS-CoV-2 has been evolving for at least 7 years

The burning question is how novel viruses acquire the ability to recognize, bind to and enter human cells for the first time – whether this is dependent only on viral proteins recognizing host cell proteins, or adaptations in other viral processes that allow replication in a human host.

Pixatimod is active in lab studies against SARS-CoV-2

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) circulating the world has caused over 9.6 million cases and over 490,000 deaths as of June 26, 2020. With neither an effective vaccine nor therapeutic drug yet available, intensive and widespread research is ongoing to develop a pharmacological intervention that will halt the global pandemic.

SARS-CoV-2 can replicate in human pediatric gastric organoids

A diverse research group from the United Kingdom, Italy, China, and Australia established a first expandable human gastric organoid culture across fetal developmental stages, supporting the hypothesis that fetal tissue seems to be much less susceptible to the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection – especially in the early stages of development.

USask researchers receive $900,000 to help strengthen Canada's rapid response to COVID-19

The Canadian Institutes of Health Research has awarded three University of Saskatchewan research teams a total of $900,000 to help strengthen Canada's rapid response to the COVID-19 pandemic which had killed more than 450,000 people worldwide.

Early childhood vaccinations may offer protection against COVID-19

A group of Lithuanian and Kurdish scientists have raised a hypothesis that the measles, mumps, and rubella (MMR) vaccine could protect children from COVID-19.

Study assesses impact of anti-SARS-CoV-2 convalescent plasma in COVID-19 disease

The current COVID-19 pandemic is still very much active in most parts of the world. In the absence of effective antiviral drugs or vaccines, scientists are studying the use of blood plasma from convalescent COVID-19 patients, banking on its neutralizing antibody content.

New assay rapidly tests SARS-CoV-2 neutralization and screens antivirals

Researchers at the University of Texas Medical Branch, Galveston, have developed a new platform that can rapidly test neutralizing antibody activity against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and perform high-throughput screening of potential antiviral agents.

FDA approved drugs active against COVID-19

With the rapid spread of the virus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) throughout the world, causing the current COVID-19 pandemic, there is an urgent need for new antivirals and vaccines to combat its spread. The current study published on the preprint server bioRxiv in June 2020 shows some of the results of the extensive repurposing of already FDA-approved drugs.

Colombian corona hounds: SAR-CoV-2 detection by dogs

A new Colombian study published on the preprint server bioRxiv in June 2020 describes the use of trained dogs to identify severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infected humans by scent alone. This would allow uninfected people to work together safely, rescuing the economy without driving up medical costs.

Growth, adaptation and neutralization of SARS-CoV-2 with acute-phase serum

One recent study published on the preprint server bioRxiv in June 2020 reports the results of growing and characterizing the virus, as well as the development of neutralizing antibodies in the serum of acutely infected hospitalized patients with COVID-19.

Dire warning on contamination of water and COVID-19 spread

A recent report by scientists in the United Kingdom and Poland and published on the preprint server medRxiv in June 2020 describes the presence of stable severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in water for up to 25 days, with the risk of infection by the contaminated water varying by the country’s environment.

Favipiravir has weak effect on SARS-CoV-2 and Hydroxychloroquine none at all in hamster model

A new study from Belgian researchers shows that antiviral drug Favipiravir could have a weak effect against the dreaded novel coronavirus or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as seen in hamster models. However, the study also finds there is no efficacy of the much-touted drug Hydroxychloroquine.

Scientists show how harmless adenovirus disrupts the heart's electrical signaling

Adenovirus, which typically can cause a common cold, has a far more dangerous impact if it reaches the heart.

UAH researchers assess treatment efficacy of naturally occurring compounds against COVID-19

The Baudry Lab at The University of Alabama in Huntsville has identified 125 naturally occurring compounds that have a computational potential for efficacy against the COVID-19 virus from the first batch of 50,000 rapidly assessed by a supercomputer.

The role of brain cells in spreading HIV

Dr. Lena Al-Harthi speaks to News-Medical about her research into HIV treatment and the role of brain cells in spreading the HIV virus.

As problems grow with Abbott’s fast COVID test, FDA standards are under fire

In mid-May, the Food and Drug Administration issued a rare public warning about an Abbott Laboratories COVID-19 test that for weeks had received high praise from the White House because of its speed: Test results could be wrong.

Research explores the biophysical behavior of SARS-CoV-2 nucleocapsid protein

In a groundbreaking paper currently available on the bioRxiv* preprint server, the researchers from the Washington University School of Medicine and Stony Brook University showed how nucleocapsid protein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is dynamic, disordered and phase separates with RNA – informing, in turn, the discovery of drugs that disrupt viral packaging.

New technology detects breast cancer using tears

Kobe University and System Instruments Co., Ltd. researchers have developed TearExo; new technology to detect breast cancer using the exosomes found in tears as biomarkers. Exosomes are a subtype of extracellular vesicles.

Researchers find prothrombotic antibodies in patients with COVID-19

Even as the COVID-19 pandemic continues to spread across the world, researchers are still trying to understand the many ways in which it can manifest and its pathogenesis. A new report published on the preprint server medRxiv* in June 2020 shows that one possible mechanism of disease in COVID-19 is the production of antiphospholipid antibodies.
