On episode #362 of the science show This Week in Virology, the virus virtuosos, with their usual verve, illuminate a new method to identify all the viral nucleic acids in a sample, and regulation of viral gene expression by codon usage. You can find TWiV #362 at www.microbe.tv/twiv.
The high mutation rate of RNA viruses enables them to evolve in the face of different selection pressures, such as entering a new host or countering host defenses. It has always been thought that the sources of such mutations are the enzymes that copy viral RNA genomes: they make random errors which they cannot correct. Now …

On episode #361 of the science show This Week in Virology, the TWiVsters discuss Frederick Novy’s return from retirement to recover a lost rat virus, and evidence for persistence of Ebolavirus in semen. You can find TWiV #361 at www.microbe.tv/twiv.
It is well known that virus populations display phenomenal diversity. Virus populations are dynamic distributions of nonidentical but related members called a quasispecies. This diversity is restricted in single cells, but is restored within two infectious cycles. Single cells infected with vesicular stomatitis virus (VSV) were isolated using a glass microcapillary, and incubated overnight to allow completion …
On episode #360 of the science show This Week in Virology, Vincent visits the University of Michigan where he and Kathy speak with Michael, Adam, and Akira about polyomaviruses, virus evolution, and virus assembly, on the occasion of naming the department of Microbiology & Immunology a Milestones in Microbiology site. You can find TWiV #360 at …
On episode #359 of the science show This Week in Virology, Vincent speaks with Blossom about her laboratory’s research on Kaposi’s sarcoma-associated herpesvirus, including how it transforms cells, the switch between lytic and latent replication, and its interaction with the innate immune system of the host.
