A chemical modification in the HIV-1 RNA genome whose function has been a matter of scientific debate is now confirmed to be key to the virus's ability to survive and thrive after infecting host cells ...

High-resolution images provide clarity into how viral proteins are separated by a protease, an important step during virus replication that is targeted by an approved COVID-19 drug. UNIVERSITY PARK, ...

Viruses use the molecular repertoire of the host cell to replicate. Researchers from the Cluster of Excellence ImmunoSensation2 at the University of Bonn, together with Japanese researchers, want to ...

How can a virus with only five proteins dominate a human cell that contains thousands? This question has long puzzled ...

This story is part of a larger series on viroids and virusoids, small infectious RNAs. It is also the fifth installment in a series on hepatitis D virus, a virusoid-like pathogen that causes serious ...

Viruses are entities that have to infect other cells in order to replicate. They may have genomes that are made of DNA or RNA. We are still discovering new types of RNA viruses, as shown in two new ...

A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, a Stanford University team reports in Nature Communications. Using advanced ...

Researchers have developed a new method to detect RNA viruses based on the triplex-forming probe technology. This innovative methodology opens up new options for detecting viruses such as SARS-CoV-2, ...

In a twist on the question, 'Which came first, the chicken or the egg?', scientists have long faced a similar question about how human adenovirus replicates: 'Which comes first, assembly of the viral ...
