Ben tenOever joins the TWiVoli to discuss the evolution of RNA interference and his lab’s finding that RNAse III nucleases, needed for the maturation of cellular RNAs, are an ancient antiviral RNA recognition platform in all domains of life.
The TWiV Council explores the finding that facial appearance affects science communication, and evidence that RNA interference confers antiviral immunity in mammalian cells.
The TWiV hosts review an analysis of gender parity trends at virology conferences, and the origin and unusual pathogenesis of the 1918 pandemic H1N1 influenza virus.
The TWiVsters reveal the puppet master: an RNA virus injected with wasp eggs that paralyzes the ladybug so that she protects the cocoon until the adult emerges.
