Endogenous retroviruses are ancient pieces of viral DNA embedded throughout mammalian genome. Thought to be relatively inert, they are not infectious, because they lack the full complement of viral ...

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 ...

The herpesvirus can manipulate our DNA with far more precision than previously thought. The virus condenses and changes the shape of our genetic material to hijack the host genes needed for ...

A team of scientists at the Helmholtz Institute for RNA-based Infection Research (HIRI) in Würzburg and the University of Regensburg has unveiled insights into how HIV-1, the virus responsible for ...

The cold sore-causing Herpes Simplex Virus (HSV-1) hijacks human cells and reconfigures its DNA within just an hour after infection, according to a new study that may help tackle the pathogen. Viruses ...

In a recent study posted to bioRxiv*, researchers evaluated the early replication kinetics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Study: Visualization of early RNA ...

Human DNA in its natural state inside cells (left) compared to eight hours after being infected with HSV-1 (right). The virus compacts the human genome’s size significantly and moves it towards the ...

Individually tailored RNA or DNA-based molecules are able to reliably fight off viral infections in plants, according to a new study. The researchers were able to fend off a common virus using the new ...

Why does Hepatitis E become chronic in some patients, and why do medications not work? To find out, an international research team led by scientists from Bochum observed a patient with chronic ...

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 ...
