A giant virus discovered in Japan is adding fuel to the provocative idea that viruses helped create complex life. Named ushikuvirus, it infects amoebae and shows unique traits that connect different ...

Most people have the Epstein-Barr (EBV) virus. Sometimes people are unaware of this virus in their body; it settles into immune cells and remains for the duration.

In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, ...

For decades, biology textbooks have drawn a firm line: viruses are not alive. They lack the machinery to reproduce on their ...

A giant virus encodes part of the protein-making toolkit of cells that gives it greater control over its amoeba host, raising questions about how it evolved and how such beings relate to living organi ...

A virus that is big enough to be seen under an ordinary light microscope co-opts its host’s systems with the help of ...

Infection with Zika virus in pregnancy can lead to neurological disorders, fetal abnormalities and fetal death. Until now, how the virus manages to cross the placenta, which nurtures the developing ...

Scientists discover how yellow fever and encephalitis viruses enter human cells, and block them with decoy molecules.

A live-cell imaging tool allowed researchers to follow influenza A virus through its life cycle in airway organoids, showing ...

Human noroviruses, GII.4 strains in particular, are the chief drivers of acute viral gastroenteritis around the world, a condition for which there are no vaccines or antivirals. Understanding how ...
