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

The tiny shell protecting the HIV virus resembles a slightly rounded ice cream cone, but there is nothing sweet about it.

Microbiologists Patrick Moreira and Purificación López-García, together with virologists Arturo Ludmir and Lynn Enquist, are at the center of a sharp debate over whether viruses count as living ...

A single influenza virus entering a host cell, visualized with VISUN. The bright spots are individual packages of viral genetic material, which are fluorescently labeled and spreading through the host ...

A team of scientists at University of Oxford have worked with multiple techniques at Diamond Light Source, to solve the structure of the influenza replication machinery and to determine how it ...

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

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 ...

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 ...

University of Delaware professor Juan Perilla (right), is co-author of a new paper that reveals a previously unknown structural role for integrase, a key HIV protein, earlier in the virus' life cycle ...
