The TWiV team describes aphid control by using a viral capsid protein to deliver a spider toxin to plants, and a human endogenous retrovirus that enhances expression of a neuronal gene.

Vincent, Dickson, and Alan consider a broad spectrum antiviral against enveloped viruses, how a plant virus induces chemical signals in the host to maximize its spread, a new way to preserve viral vaccines at tropical temperatures, and the continuing story of XMRV and chronic fatigue syndrome.
