Virus particles are metastable: they must be highly stable, to protect the nucleic acid while traveling from host to host or cell to cell, and then come apart to liberate the genome into the cell. New insight into this uncoating process comes from beautiful images of feline calicivirus showing formation of a portal on the …
The TWiV crew reveal a unique portal on the calcivirus capsid formed upon receptor engagement, and the regulation of interferon responses in virus-infected cells by methylation of mRNA.

Viruses can be transmitted to completely new host species that they have not previously infected. Usually host defenses stop the infection before any replication and adaptation can take place. On rare occasions, a novel population of viruses arises in the new host. These interspecies infections can sometimes be deduced by sequence analyses, providing a glimpse …
