For over 50 years the RNA genome of picornaviruses (illustrated below for poliovirus) was thought to be translated into a single, long polyprotein. All this time a very small upstream open reading frame (uORF) has gone undetected – until now.
The TWiVaniellos discuss a thermostable poliovirus empty capsid vaccine, and two cell genes that act as a switch between entry and clearance of picornavirus infection.

On episode #374 of the science show This Week in Virology, the TWiVniks consider the role of a cell enzyme that removes a protein linked to the 5′-end of the picornavirus genome, and the connection between malaria, Epstein-Barr virus, and endemic Burkitt’s lymphoma.

On episode #365 of the science show This Week in Virology, Vincent, Alan, and Kathy trace the feud over genome editing, a new virus discovered in human blood, and the origins of hepatitis A virus. You can find TWiV #365 at www.microbe.tv/twiv.
Foot-and-mouth disease virus (FMDV) infects cloven-hoofed animals such as cattle, pigs, sheep, goats, and many wild species. The disease caused by this virus is a substantial problem for farmers because infected animals cannot be sold. Transgenic pigs have now been produced which express a short interfering RNA (siRNA) and consequently have reduced susceptibility to infection with FMDV. …
Rhinovirus is the most frequent cause of the common cold, and the virus itself is quite common: there are over 160 types, classified into 3 species. The cell receptor has just been identified for the rhinovirus C species, which can cause more severe illness than members of the A or B species: it is cadherin-related family …
