Influenza's Spike Motor and the Spaghetti Drive

Igor Kulic , Institut Charles Sadron, Strasbourg
While often believed to be only a passive agent that merely exploits its host\'s metabolism, the influenza virus has recently been shown to actively roll across glycan-coated surfaces. In this talk we present what we currently know about this new form of motility and develop a quantitative physical model. We conclude by discussing the general concept and various instances of a monowheel engine. We show that many filaments beyond influenza, from fishing line to spaghetti, exhibit active rolling propulsion across surfaces when driven out of equilibrium by fluxes traversing the surface.
