From the University of Texas at Austin, Vincent and Rich speak with Chris Sullivan about his work on miRNAs encoded in the genomes of polyomaviruses and papillomaviruses, and how an RNA triphosphatase restricts hepatitis C virus replication.

During a trip to California, Vincent visited Peter Sarnow and Bert Semler and spoke with them about their work on internal ribosome entry, and the requirement for a cellular microRNA for hepatitis C virus replication.
