The antiviral drug molnupiravir has been shown to reduce the transmission of SARS-CoV-2. Now, researchers reveal the molecular mechanism behind its action – the drug incorporates RNA-like building blocks into the RNA genome of the virus.

Researchers from the University of Birmingham have confirmed the speed, accuracy and simplicity of a novel, highly sensitive testing method for COVID-19 that can be deployed at entertainment venues, airport arrival terminals, and in remote settings where clinical testing laboratories are not available.

A new electrochemical COVID-19 test has been developed by Penn researchers using electrodes made from graphite—the same material found in pencil lead. The electrodes reduce the cost to $1.50 per test and require only 6.5 minutes to deliver 100-pecent-accurate results from saliva samples and up to 88 percent accuracy in nasal samples.

Scientists at the NIH have developed a new sample preparation method to detect SARS-Cov-2. The method bypasses extraction of the virus’ genetic RNA material, simplifying sample purification and potentially reducing test time and cost.

Scientists have used advanced imaging methods to reveal how the production of the Alzheimer’s-associated protein amyloid beta (Aβ) in the brain is tightly regulated by cholesterol.

Quantum engineers have removed a major obstacle standing in the way of quantum computers becoming a reality. They have discovered a new technique they say will be capable of controlling millions of spin qubits, the basic units of information in a silicon quantum processor.

Researchers have described a new method for counting mutations and have found that one in 15 men are likely to carry mutations that could adversely affect their offspring.

When given the choice between a free meal and performing a task for a meal, cats would prefer the meal that doesn’t require much effort. While that might not come as a surprise to some cat lovers, it does to cat behaviorists.

It’s long been known that opioid overdose deaths are caused by disrupted breathing, but the actual mechanism by which these drugs suppress respiration was not understood. Now, a new study by Salk scientists has identified a group of neurons in the brainstem that plays a key role in this process.

In one of the most comprehensive computational efforts to explore heritable genomic variations, researchers have pinpointed nine processes during which most human genetic mutations tend to arise.
