To replicate, viruses need to make multiple copies of their genome. Almost all encode a protein that does this for them. Hepatitis D virus doesn't. How does it replicate?

Viruses display both life-like and non-living traits, which influences how we approach treatments like antiviral drugs designed to block their replication inside host cells.

In 2015, an outbreak of Zika virus, driven by a heavy rain season and subsequent boom in the virus’s host mosquito population, caused thousands of babies in Brazil to be born with severe ...

UCLA researchers have created miniature stem cell-based organoid models of human lungs, hearts and brains to study how ...

Researchers at San Diego State University and Michigan State University are shedding new light on how viruses meticulously ...

Vampire viruses prey on other viruses to replicate themselves This strange new microbial discovery may hold the key to new antiviral therapies ...

The COVID-19 virus hijacks the machinery of testicular cells that produce the hormone testosterone in order to replicate.

In contrast, when a virus hijacks a host cell's DNA replication machinery, it replicates hundreds of times. This "unlicensed" replication is not subject to the same quality control and is much ...

Researchers have shown for the first time how Merkel cell polyomavirus (MCV), which causes an aggressive skin cancer called Merkel cell carcinoma, initiates DNA replication in host cells.

Researchers discovered a satellite virus latching onto the neck of another virus called MindFlayer. Studying the viral arms race between similar viruses could lead to new ways to fight infections.
