Hepatitis D “virus” is a virus in name only. Underneath the hood, it more closely resembles viroids and virusoids: it is a small circular RNA that, due to high sequence complementarity, folds ...

Their study shows that RNA viruses can live in high-temperature environments (70℃-80℃), where no RNA viruses have been observed before. In addition to the two known RNA virus kingdoms, a third ...

Hepatitis B virus, a killer of more than one million people each year, is a notoriously wily virus, often lingering and resurfacing even after treatment. But, thanks to a new class of drugs, its luck ...

Where a virus such as SARS-CoV-2 is made up of nearly 30,000 nucleotides —the basic building blocks of DNA and RNA— viroids only contain between 220 to 450 nucleotides.

Missed viruses In 2022, Babaian and his colleagues searched 5.7 million genomic samples archived in publicly available databases and identified almost 132,000 new RNA viruses 2.

To vaccinate against a virus, we typically inject a person with a disabled form of a virus. That can be a little frightening to think about. mRNA vaccines take that concern away because they are not ...

In fact, a new study by the Tuschl laboratory introduces a proof-of-concept for a novel class of antivirals that would target a type of enzyme essential not just to SARS, but also many RNA viruses ...

A new University of California, Irvine-led study uncovers how a protein, APOBEC3B, could protects cells against many different types of RNA viruses like respiratory syncytial virus (RSV), SARS ...

A cousin of DNA, RNA helps cells make proteins and also forms the basis of various viruses. The scientists uncovered 91 RNA viruses in 28 of the worm species studied, representing about 70% of the ...

In a recent paper published in Science Translational Medicine, scientists report that a class of drugs, called RNA interference (RNAi) therapeutics, represent a major advancement in the treatment of ...
