A study reveals how two proteins cooperate in a key early step of antiviral detection, as reported by researchers at Science ...

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

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 ...

Human norovirus, a positive-strand RNA virus that is the leading cause of viral gastroenteritis accounting for an estimated 685 million cases and approximately 212,000 deaths globally per year, has no ...

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, ...

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 ...

For decades, biology textbooks have drawn a firm line: viruses are not alive. They lack the machinery to reproduce on their own, they carry no metabolism, and they depend entirely on host cells to ...
