High-speed video shows how charged insects (a bee, a fly and an aphid) falling toward a spider web deform the silk by electrostatic attraction before they make contact. The final frames shows how a silk thread rapidly deforms to stick to a charged water droplet.

Topic: "The Future of Biofuels: A Business Perspective" Speaker: David L. Godwin. Vice President, Minerals and Energy Products, Weyerhaeuser This lecture will discuss and frame the cellulosic biofuels business opportunity and present some practical solutions to some of the critical path elements. The renewable fuel mandates at both the state and federal level have created the demand for green energy. Research and pilot testing are taking place all over the world and many people in both the science and business community believe the time of commercially available biofuels is close at hand. But, the success and commercialization of biofuels will only be achieved when solutions address both the public concern associated with environmental impacts and create a reasonable economic return for the potential large capital investments.
