Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes COVID-19, uses a sophisticated tactic to evade the human body's defense ...

Many positive strand RNA viruses encode helicases, but their distinct functions in viral replication cycles is poorly understood. Here, we identify a mutation in the helicase domain of HCV ...

They say that change takes time. Well, that's not the case for RNA. The small biological molecule acts like a switchboard operator, capable of changing its shape every few milliseconds so it can ...

Current therapeutics for chronic hepatitis B virus (HBV) infection are insufficient due to immune exhaustion caused by high circulating hepatitis B surface antigen (HBsAg) levels. Here, an HBV S ...

An interdisciplinary team of Rice University researchers has uncovered previously unknown relationships between bacteriophages—viruses that infect bacteria—and their bacterial hosts, offering a ...

Cold sore virus takes over human DNA within just one hour, study finds - Study is first to prove that herpes virus reshapes ...

Viruses rely on hosts to survive. But some viruses are more effective at reproducing than others. Now, new research has shown that the herpes virus, more specifically herpes simplex virus type 1 ...

Researchers from the University of Osaka have demonstrated that mitochondrial hyperfusion, when induced by low levels of DRP1 ...

What is the full form of RNA? Explore its meaning, single-stranded structure, functions, how it differs from DNA, its role in ...

In simple terms: a virus is a tiny package of genetic instructions with a delivery system. Outside a cell it is metabolically inert. Once inside a susceptible cell, it redirects the cell's machinery ...
