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 ...

Herpes simplex virus type 1 (HSV-1) infection dramatically remodels the host cell's nuclear structures. Infection leads to ...

In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma ...

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 ...

A research team at the University of Würzburg has deciphered another aspect of poxviral gene activation. The study reveals a ...

The story of how life began on Earth grows even more intriguing when viruses enter the picture. These microscopic particles are thought to have ...

How flu viruses enter cells has been directly observed thanks to a new microscopy technique with the potential to revolutionize research on membrane biology, virus–host interactions and drug discovery ...

For the first time, scientists have been able to watch the flu virus live as it infects human airway cells. They developed a ...

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.
