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 broad geographic and evolutionary dispersal of betacoronaviruses from African bats

A research group from Nigeria found evidence of long-distance transmission and dispersal between bat coronaviruses isolated in Africa and the ones Europe and Asia, as described in a new paper available on the preprint server bioRxiv.

More research is needed to determine if fecal matter spreads COVID-19, say researchers

Early studies show evidence of COVID-19 genetic material in fecal matter, but more work is needed to determine if the virus can be spread through stool, according to a new review paper from a Rice University epidemiologist.

Mouse model helps track organism’s development from embryonic stage to adulthood

Scientists at the Stem Cell Research program at Boston Children's Hospital and Dana-Farber Cancer Institute/Harvard Medical School have devised a mouse model that lets researchers track every cell in the body, from the embryonic stage until adulthood.

Tissue Solutions and CBSB join forces to increase COVID-19 sample availability

The UK’s leading supplier of human tissue samples is joining forces with a Cambridge Biobank to provide COVID-19 samples for scientists.

Viral shedding among pre-symptomatic COVID-19 patients finds study

Researchers from Bangalore, India, have found that 68 percent of pre-symptomatic patients with COVID-19 may be shedding the virus and potentially infecting others. Their study titled, “Quantitative COVID-19 infectiousness estimate correlating with viral shedding and culturability suggests 68% pre-symptomatic transmissions,” was published on the open-access preprint server Medrxiv.

Viral shedding seen in plasma donors who have recovered from COVID-19

Researchers from the University of Wisconsin-Madison have found that plasma donors who have recovered from the deadly COVID-19 infection were still shedding viral RNA. This could be significant they write in their article titled, “Prolonged viral RNA shedding after COVID-19 symptom resolution in older convalescent plasma donors,” that is published on the preprint server Medrxiv* prior to peer review.

BGU researcher develops one-minute COVID-19 breath test

Ben-Gurion University of the Negev's Prof. Gabby Sarusi has developed and is now validating a test that identifies carriers of the COVID-19 virus in less than a minute with greater than 90% accuracy and at a dramatically lower price than any other method available.

Researchers study how brain cancer cells acquire resistance to radiation

In a vertical climb to avoid collision with a towering mountain, a plane ejects cargo to gain altitude. Investigators at the University of Minnesota showed that cancer cells perform similar feats in escaping the killing effects of radiation.

New clinical trial to investigate the efficacy of ivermectin against COVID-19

Clínica Universidad de Navarra and the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, have launched a clinical trial to investigate the efficacy of ivermectin against COVID-19.

Researchers identify a group of dysregulated genes in autism

Autism has long been associated only with behavioral and environmental factors, but the role of genetics in its development is now increasingly evident. Some 100 genes have been found to play a role in autism spectrum disorder, and another thousand are being studied to the same end.

Low-cost PCR test designed to detect coronavirus

The project of Consuelo Rubio has been among those chosen for the call of the Valencian System of Innovation and Research for the COVID-19 emergency.

Potential targets discovered for COVID-19 therapy

A team of biochemists and virologists at Goethe University and the Frankfurt University Hospital were able to observe how human cells change upon infection with SARS-CoV-2, the virus causing COVID-19 in people.

Research reveals how long SARS-CoV-2 survives on surfaces, in feces and urine

A new study published on the preprint server medRxiv* in May 2020 shows that the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that causes COVID-19 disease can remain viable for a maximum of one week on smooth environmental surfaces, for several hours in human feces, and for a maximum of 4 days in human urine. This knowledge could help guide disinfection policies to control the virus spread.

Research explores how COVID-19 is spreading and mutating in the environment

A multi-disciplinary team of experts in virology and computer modeling has quickly assembled at San Diego State University to learn more about how the new coronavirus (COVID-19) spreads in the environment and how its trajectory can be better predicted.

Study shows why older individuals are vulnerable to COVID-19

A group of tiny RNA that should attack the virus causing COVID-19 when it tries to infect the body are diminished with age and chronic health problems, a decrease that likely helps explain why older individuals and those with preexisting medical conditions are vulnerable populations, investigators report.

Analysis of single-cell data indicates that SARS-Cov-2 targets many cell types

Before it can sicken people, the new coronavirus must first sneak into their cells. But not any cell will do. The virus can enter only those with a certain combination of molecules on their surfaces.

Scientists are looking for alternate methods to predict the spread of COVID-19

With the ongoing challenges associated with large-scale testing for COVID-19--including test kit shortages, stringent testing criteria and the inherent limitations of current tracking systems on mildly symptomatic and asymptomatic populations, scientists are looking for alternate methods to boost testing in order to predict the spread of the disease.
