When viruses are introduced into a new population, selection pressures can lead to evolution of both pathogen and host. The pathogen must adapt to a new host, while the latter can become resistant to infection, leading to an arms race. An archetypal example of such host-pathogen evolution is illustrated by ...

The TWiV hosts present two potentially seminal papers, on long-distance chemoattraction of a host by a chlorovirus, and replication of a nanovirus across multiple cells in a plant.

Viruses have no intrinsic means of locomotion, but because of their small size their movement can be driven by Brownian motion. Propagation of viruses is dependent on essentially random encounters with potential hosts and host cells. An exception appears to be chloroviruses, which can attract their host from a distance. ...
