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.

Activation of fatty acid receptor causes masculinization of Japanese rice fish

A research collaboration based at Kumamoto University (Japan) has found that activation of PPARα, a fatty acid receptor that detects fatty acids in cells and regulates physiological functions, causes masculinization of Japanese rice fish (medaka).

D614G spike mutation increases infectivity of SARS-CoV-2 and neutralization susceptibility

As the COVID-19 pandemic progresses, it is crucial to track the viral changes in order to link the clinical and epidemiological features of the disease with these mutations. A new study published on the preprint server bioRxiv* in September 2020 reports on a common severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mutation, D614G, and its effects on the virus.

Researchers develop novel model to study factors that cause type 2 diabetes

Using cells taken from patients with type 2 diabetes and new techniques to convert them into specialized precursors of muscle cells, researchers have developed a novel 'disease-in-a-dish' model to study the basic molecular factors that lead to the development of type 2 diabetes.

Research provides a map of coronavirus entry factors across the human body

An infection with the coronavirus SARS-CoV-2 can affect multiple organs. With this in mind, researchers of the German Center for Neurodegenerative Diseases and Cornell University in the US have investigated cellular factors that could be significant for an infection.

Understanding SARS-CoV-2 evolution requires more focus on structural variants

Researchers in the United States and Canada warn that more attention needs to be paid to the role that structural variants and recombination in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have played in the evolutionary history of the virus.

Researchers propose unified nomenclature of neurons to cure brain disease

The human brain has about 100 billion neurons, linked in intricate ways, that the Spanish neuroanatomist Ramón y Cajal compared to "the impenetrable jungles where many investigators have lost themselves."

Bioengineering technique that boosts protein production could lead to effective COVID-19 vaccine

A bioengineering technique to boost production of specific proteins could be the basis of an effective vaccine against the novel coronavirus that causes COVID-19, new research suggests.

Combined point-of-care nucleic acid and antibody testing increases COVID-19 detection

A Cambridge hospital has piloted the use of combined rapid point-of-care nucleic acid and antibody testing for SARS-CoV-2 infection after researchers at the University of Cambridge showed that this approach was superior to virus detection alone for diagnosing COVID-19 disease.

NIH provides scale-up and manufacturing support for new COVID-19 testing technologies

The National Institutes of Health today announced $129.3 million in scale-up and manufacturing support for a new set of COVID-19 testing technologies as part of its Rapid Acceleration of Diagnostics (RADx) initiative.

Blood test can identify patients at high risk of severe COVID-19

A blood test on hospital admission showing the presence or absence of SARS-CoV-2 can identify patients at a high risk of severe COVID-19.

ACE2/TMPRSS2 not expressed in pancreatic islet endocrine cells

A new study by researchers at the Vanderbilt University Medical Center and the University of Pennsylvania Perelman School of Medicine and published on the preprint server bioRxiv* in August 2020 reports that both key enzymes that are required for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) entry into the human host cell are lacking in the beta cells of the pancreatic islet. This rules out the direct injury hypothesis for impaired glucose control in patients with COVID-19 disease.

SARS-CoV-2-RNA viremia is a robust marker of critical illness in COVID-19

A new study by a large team of Spanish researchers and published on the preprint server medRxiv* in August 2020 reports that the presence of viral RNA in the blood is a useful marker of impending acute disease and can help triage COVID-19 disease patients who will require hospital care.

Negligible ACE2 expression in human beta-cells

Now, a new study published on the preprint server bioRxiv reports that even though the fatality rate is significantly higher in diabetics, there is no evidence that this is due to direct viral infection of pancreatic beta cells, which produce the key hormone in glucose homeostasis, namely insulin.

Promising new candidate 'virus-like particle' vaccine for COVID-19

Researchers in the UK and Taiwan have demonstrated the potential of a new candidate vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the virus responsible for the current coronavirus disease 2019 (COVID-19) pandemic.

Silicon nitride shows potent SARS-CoV-2 neutralization capability

A new study published on the preprint server bioRxiv* in August 2020 shows that the man-made compound silicon nitride, which is used in medical implants and high mechanical performance engineering applications, is capable of inactivating severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at varying concentrations without causing cell cytotoxicity. This finding should be investigated to develop disinfectants to clear the virus from surfaces, preventing its spread.
