Ted and Welkin inform the TWiV team how the evolution of ancient retroviruses can be inferred by their sequences in the genomes of modern mammals, and join in a discussion of virus dispersal during different methods for drying hands.

This episode was recorded at the 34th Annual Meeting of the American Society for Virology, where Vincent, Rich, and Kathy spoke with Joan Steitz, a tireless promoter of women in science and one of the greatest scientists of our generation.

The TWiV four discuss an mRNA-based influenza vaccine, and a phage tubulin that forms a filamentous array in the host cell that is needed for positioning viral DNA.

Vincent and guests Rachel Katzenellenbogen, Roger Hendrix, and Harmit Malik recorded TWiV #135 live at the 2011 ASM General Meeting in New Orleans, where they discussed transformation and oncogenesis by human papillomaviruses, the amazing collection of bacteriophages on the planet, and the evolution of genetic conflict between virus and host.
