On the dinner plate that is planet Earth, there exists a veritable buffet of viruses — an amount of biomass that is the equivalent of about 25 billion human beings. So perhaps it’s a bit baffling that ...

Encouraged by these results, Dudin, Dey, Guichard, and Hamel launched a close collaboration. Three years later, their work has produced near-encyclopedic insight into hundreds of protist species and ...
