A Beautiful Visualization of Flagellar Motor Mechanics and Assembly

A few notes:

Bacterial Flagellum - A Sheer Wonder Of Intelligent Design - video http://www.metacafe.com/watch/3994630 Biologist Howard Berg at Harvard calls the Bacterial Flagellum “the most efficient machine in the universe." The Bacterial Flagellum – Truly An Engineering Marvel! - Jonathan M. - December 2010 https://uncommondescent.com/intelligent-design/the-bacterial-flagellum-truly-an-engineering-marvel/ 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. http://www.sciencedirect.com/science/article/pii/S096098220602286X Electron Microscope Photograph of Flagellum Hook-Basal Body http://www.skeptic.com/eskeptic/08-08-20images/figure03.jpg "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?" - Shin-Ichi Aizawa - What Is Essential for Flagella Assembly? - 2009 - Pili and Flagella - Chpt. 6 Bacterial Flagella - More Perfect Than We Imagined - Optimization of Molecule Counting - video http://fora.tv/2010/11/03/More_Perfect_Than_We_Imagined_A_Physicists_View#chapter_12

Persistent dynamic entanglement from classical motion: How bio-molecular machines can generate non-trivial quantum states – November 2011 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. http://arxiv.org/abs/1111.2126

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.JoeCoder
