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 much of modern biology, scientists argued that viruses are not alive, pointing to a basic limitation: they cannot make proteins on their own and must depend entirely on the cells they infect for ...

High-throughput neutralisation tests could lead to a better understanding of the evolution of human influenza.

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 ...

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

In 1990, I finished my PhD on primate evolution and went to my postdoc in Davis, California, USA. It was meant to be on fruit fly ...

In the murky waters of Ushiku-numa, a freshwater pond just northeast of Tokyo, a microscopic drama has been playing out for eons, entirely unseen. Here, single-celled amoebae drift through the silt, ...

Scientists studying the virus’s continuing evolution, and the body’s immune responses, hope to head off a resurgence and to better understand long Covid. By Apoorva Mandavilli Apoorva Mandavilli has ...

In the early, uncertain days of the coronavirus pandemic, scientists delivered one comforting pronouncement: The virus that caused COVID mutates rather slowly. If that remained true, the virus would ...

Over the last century, a once-deadly mosquito-borne virus has evolved so that it no longer sickens humans. New research shows that changes in the virus’s ability to target human cells paralleled the ...
