Scientists deconstruct the protein-based machine responsible for SARS-CoV-2 replication

In February 2020, a trio of bio-imaging experts were sitting amiably around a dinner table at a scientific conference in Washington, D.C., when the conversation shifted to what was then a worrying viral epidemic in China.

Scientists identify existing drugs that may inhibit SARS-CoV-2 virus

The COVID-19 pandemic has caused more than 600,000 deaths in the United States since the start of 2020 and more than 4 million globally.

Mapping dengue fever hot spots can predict future outbreaks of Zika and chikungunya

Data from nine cities in Mexico confirms that identifying dengue fever “hot spots” can provide a predictive map for future outbreaks of Zika and chikungunya. All three of these viral diseases are spread by the Aedes aegypti mosquito.

New method expands view into activity of single cells

Researchers have devised a way to multiply by more than ten-fold the accessible details of gene activity in individual cells. It's a big leap in the effort to understand cancer development, brain function, immunity and other biological processes driven by the complex interactions of multitudes of different cell types.

Pfizer-BioNTech COVID-19 vaccine may not be associated with adverse effects on fertility and breastfeeding, says study

A recent study by researchers in Singapore shows the absence of evidence for adverse effects on fertility or the presence of the vaccine mRNA (messenger ribonucleic acid) in breast milk, following the administration of the Pfizer BNT162B2 COVID-19 vaccine. This supports efforts to prevent the spread of false information about the effects of the vaccine.

Nanopore analysis identifies pseudouridine modifications in SARS-CoV-2

In a paper recently uploaded to the preprint server bioRxiv* by Fleming, Mathewson & Burrows (May 10th, 2021), nanopore devices are developed that allow identification of the passage of pseudouridine through a protein sensor. This further allowed the group to identify five conserved pseudouridine sites on the 3’ end of SARS-CoV-2 sub-genomic RNAs, which could potentially be beneficial to the virus in immune evasion.

MIT researchers generate the complete gene annotation of SARS-CoV-2 genome

In early 2020, a few months after the Covid-19 pandemic began, scientists were able to sequence the full genome of the virus that causes the infection, SARS-CoV-2. While many of its genes were already known at that point, the full complement of protein-coding genes was unresolved.

The ancestor of SARS-CoV-2’s Wuhan strain was circulating in late October 2019

The SARS-CoV-2 was first reported in a case from Wuhan, China, in December 2021, and subsequently became the cause of the COVID-19 pandemic that is ravaging the world today. A new study in the journal Molecular Biology and Evolution tracks its variants all over the world since the onset of the pandemic.

High-throughput system can regulate gene expression for treating sickle cell disease, beta thalassemia

St. Jude Children's Research Hospital scientists have developed an integrated, high-throughput system to better understand and possibly manipulate gene expression for treatment of disorders such as sickle cell disease and beta thalassemia. The research appears today in the journal Nature Genetics.

Advanced-stage kidney cancer more common in Hispanic and Native Americans in Arizona

Recently published research from the University of Arizona Health Sciences shows that advanced-stage kidney cancer is more common in Hispanic Americans and Native Americans than in non-Hispanic whites, and that both Hispanic Americans and Native Americans in Arizona have an increased risk of mortality from the disease.

Researchers reveal how the brain may adapt to processing complex information

Human decision-making depends on the flexible processing of complex information, but how the brain may adapt processing to momentary task demands has remained unclear.

Ebola virus's key protein uses molecular triggers in the human cell to change shape

The human genome contains the instructions to make tens of thousands of proteins. Each protein folds into a precise shape-;and biologists are taught that defined shape dictates the protein's destined function.

Inhibition of nsp14 methyltransferase as a potential antiviral target for SARS-CoV-2

Beyond vaccination, the broad-spectrum antiviral medication remdesivir has robust clinical evidence and is known as the best antiviral treatment to reduce severe COVID-19 infection in hospitalized patients. Research led by John F.X. Diffley of the Chromosome Replication Laboratory suggests a potential therapeutic target for treatment development is the viral RNA cap methyltransferases, essential for viral protein translation and immune evasion.

Screening for SARS-CoV-2 non-structural protein 14 inhibitors

In a paper recently uploaded to the preprint server bioRxiv* by Diffley et al. (April 8th, 2021), inhibitors of one essential SARS-CoV-2 non-structural protein are explored, with four compounds, in particular, identified as potential antiviral leads that exhibit synergistic effects with antiviral drug remdesivir.
