RNA-chopping enzyme Dicer stabilizes mammalian chromosomes with the help of BRD4 activator

Cells use RNA as a versatile tool to regulate the activity of their genes. Small snippets of RNA can fine-tune how much protein is produced from various genes; some small RNAs can shut genes off altogether.

Potential Covid-19 vaccine may offer an inexpensive, easy-to-store alternative to RNA vaccines

While many people in wealthier countries have been vaccinated against Covid-19, there is still a need for vaccination in much of the world.

Engineered SARS-CoV-2 immunogens elicit broadly neutralizing antibodies

New research describes a novel approach whereby SARS-2 antigens were analyzed for conserved sites that may be targeted by broadly neutralizing antibodies that will confer immunity to other Sarbecoviruses.

Application of various nanoparticle-capsulated siRNA as therapeutics for SARS-CoV-2 infection

In a review published in the International Journal of Molecular Sciences, researchers have been reviewing the use of siRNAs to target coronaviruses.

Discovery illuminates a blueprint to develop new antibiotics for killing bacteria

The Centers for Disease Control and Prevention estimates that more than 2.8 million Americans experience antibiotic-resistant infections each year; more than 35,000 die from those infections.

Study identifies cellular receptors for alphaviruses shared across mosquitoes, humans, and animals

A new study led by researchers at Harvard Medical School has identified a set of cellular receptors for at least three related alphaviruses shared across mosquitoes, humans, and animals that host the virus.

How diet, supplements and lifestyle changes can help battle COVID

A recent editorial in the journal Nutrients emphasizes how efficacious non-pharmacological interventions in conjunction with the promotion of healthy lifestyle and dietary patterns may improve overall health status and reduce the risk of infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), as well as the potential adverse effects of coronavirus disease 2019 (COVID-19).

Scientists discover a division of labor between genetic switches

Two X chromosomes are actually one too many. Female mammalian cells hence switch off one of them – but only when the cells start to specialize into tissues.

Production of functional SARS-CoV-2 spike protein in single-cell green alga

A new study uses a novel algal platform for the generation of the SARS-CoV-2 spike protein.

Extended host range for SARS-CoV-2 variants of concern

Researchers used viral pseudotyping to examine whether variants of concern had different host ACE2 receptor usage patterns.

Researchers identify compounds that tackle fungal infections in a new way

Current medications aren't particularly effective against fungi. The situation is becoming more challenging because these organisms are developing resistance to antimicrobial treatments, just as bacteria are.

Researchers investigate how intestinal bacteria distribute metabolic products in membrane vesicles

Bacteria in the intestine pack a wide spectrum of their biomolecules into small capsules. These are transported via the bloodstream to various organs in the body and even absorbed and processed by nerve cells in the brain.

Study uncovers a process in cells that may limit infectivity of SARS-CoV-2

Scientists at the National Institutes of Health have found that a process in cells may limit infectivity of SARS-CoV-2, and that mutations in the alpha and delta variants overcome this effect, potentially boosting the virus's ability to spread.
