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 ...
How did viruses evolve? Are they a streamlined form of something that existed long ago, or an ultimate culmination of smaller genetic elements joined together? Aa Aa Aa The evolutionary history of ...
Researchers have proposed a new evolutionary model for the origin of a kingdom of viruses called Bamfordvirae, suggesting a billion-years evolutionary arms race between two groups within this kingdom ...

Are viruses actually alive or a totally different kind of thing?
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 ...
Scientists in Japan have discovered a previously unknown giant virus, offering new insight into this enigmatic category of viruses – and possibly also into the origins of multicellular life. The virus ...
In a recent study published in Emerging Infectious Diseases, researchers determined the zoonotic transmission potential of influenza A viruses (IAVs) H3 subtype of avian, equine, and swine origin. H3 ...
WASHINGTON (AP) — A crucial question has eluded governments and health agencies around the world since the COVID-19 pandemic began: Did the virus originate in animals or leak from a Chinese lab? Now, ...
