  1. Chrome 19, Windows XP, no page zoom.

    The right side of the video is cropped off. http://i.imgur.com/uIRWN.png

    has a width of 520px, but the iframe embed code copied from YouTube is 640. Try using this embed code to make it fit:

    <iframe width=”520″ height=”390″ src=”http://www.youtube.com/embed/Ey7Emmddf7Y” frameborder=”0″ allowfullscreen></iframe>

    Fiddle with the width/height if it’s not exactly right.

  2. Wow, a great video!

  3. A few notes:

    Biologist Howard Berg at Harvard calls the Bacterial Flagellum
    “the most efficient machine in the universe.”

    Bacterial Flagellum: Visualizing the Complete Machine In Situ
    Excerpt: Electron tomography of frozen-hydrated bacteria, combined with single particle averaging, has produced stunning images of the intact bacterial flagellum, revealing features of the rotor, stator and export apparatus.

    Since the flagellum is so well designed and beautifully constructed by an ordered assembly pathway, even I, who am not a creationist, get an awe-inspiring feeling from its ‘divine’ beauty.,, if the flagellum evolved from a primitive form, …where are the remnants of its ancestor? Why don’t we see any intermediate or simpler forms of flagella than what they are today? How was it possible that the flagella have evolved without leaving traces in history?

    Excerpt: We also show how conformational changes can be used by an elementary machine to generate entanglement even in unfavorable conditions. In biological systems, similar mechanisms could be exploited by more complex molecular machines or motors.
