1. Gecko Adhesion as a Model System for Integrative Biology, Interdisciplinary Science, and Bioinspired Engineering: Video 5

    from Annual Reviews / Added

    A video from the 2014 review by Kellar Autumn, Peter Niewiarowski, and Jonathan B. Puthoff, "Gecko Adhesion as a Model System for Integrative Biology, Interdisciplinary Science, and Bioinspired Engineering," from the Annual Review of Ecology, Evolution, and Systematics: http://www.annualreviews.org/doi/abs/10.1146/annurev-ecolsys-120213-091839?utm_source=vimeo&utm_medium=es.autumn&utm_campaign=suppvideo Shown: Gecko setae adhere when preloaded and dragged along the direction of curvature of the setae (this is in the same direction geckos use when they climb). In the lower left, the normal force (blue line) is compressive initially during the load step, but immediately following the drag step, strong adhesion occurs (negative normal force) and the setae are drawn into tension. Notably, adhesion is sustained even as the setae slide across the substrate. The lower right plot illustrates frictional adhesion: Adhesion is coupled to friction, and the resultant force angle is approximately 30°. Adhesion is controlled by the shear force. During the pull step, shear force decreases, and adhesion returns to zero without the tacky behavior common to conventional adhesive tapes.

In the lower left, a compression force (blue line) develops during the load step. Friction (shear force) is approximately 0.25 of the compression force, as expected for conventional friction of hard dry materials in contact. There is no measurable adhesion when setae are pushed against their curvature: This is the anti-adhesive direction.

            I produced this echidna Creaturecast as an assignment for Invertebrate Zoology (BIOL 0410). CreatureCast is a blog produced by Invertebrate Zoology professor Casey Dunn. CreatureCasts are short videos that tend to focus on the morphology of animals. My project was completed over the span of 2-3 months and involved very long hours recording audio and taking stills using high-res digital cameras. Each piece of the video was hand-drawn and crafted by yours truly.

                  This artistic project investigates the morphology of fungi and genesis of geometries on living and growing membranes and ultimately how images can be generated by natural processes. Methods Fungi are being cultivated. Young fruiting bodies are carefully tattooed with basic geometries. A tattoo machine as used for human skin is the tool. Mushrooms are tattooed when they are still small. While the fruiting body is growing, the shape of the mushroom membrane expands - hence the tattooed image changes as well.

                    The place is Hong Kong. The year is 2035. Historically, Hong Kong has lent itself as being a destination for squatting citizens and Chinese refugees. As China's demographics diminish due to the one-child-policy, an influx of Chinese refugees cross the boarder into Hong Kong. This is the beginning of a formulation of an anarchist movement as the extremely poor citizens act out against the extremely rich, with the hong Kong government stepping in as a mediator between the two.
