Viruses acquire genes from eukaryotes — organisms whose cells store their DNA in a nucleus — and use them for their own function. Conversely, eukaryotes acquire genes from viruses to bring new ...
Researchers have shed new light on how viral evolution, population immunity, and the co-circulation of other flu viruses shape seasonal flu epidemics. Researchers have shed new light on how viral ...
Dr. Cobey studies the interaction of immunity, virus evolution and transmission at the University of Chicago. Dr. Bloom and Dr. Starr study virus evolution at Fred Hutchinson Cancer Research Center in ...
The story of life’s beginnings gets stranger when you look closely at viruses. These tiny entities seem to sit at the edge of biology. They carry genetic material, but they cannot make proteins on ...
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 ...
In the fall of 2019, the world began one of the largest evolutionary biology experiments in modern history. Somewhere near the city of Wuhan in eastern China, a coronavirus acquired the ability to ...
