A testimony to the Wisdom and Awesomeness of our Creator

That is actually a MOTOR PROTEIN and they REALLY DO look like that and perform in that mannor, completely autonomic and on their own. They are known as Kinesin and Dynesin motor proteins. They can shuttle vesicles (to release their cargo content outside the cells) or organelles (cellular versions of organs) to their destination. They do this on a protein highway, known as Micro tubules,which polymerize and depolymerize entirely on their own, by under going conformational changes which alter their structure causing them to "move" one "foot" at a time. The microtubule not only acts as a motor highway but it also acts as cellular framework or support structures along with other intermediate filaments for the cell.

Yes, I was looking at that thing going, huh? That can't be actually how it works... But you answered that question for me. That is too cool for school. :)
Thanks again. Keep those bad boys coming...

Alex,
I'm much more of a History guy than a Science guy. Ever since I was a kid, I've enjoyed gazing at the stars and finding constellations, reading about their origins/stories, etc. But then I took an astronomy class, and I was disappointed with how scientific/mathematical it was. I like flowers, trees, and animals, but I only took Biology because it was a requirement, and I didn't like it.
This video is awesome to see. It is awesome for you because you know what's going on, but it's also awesome for people like me, because we can see how it works without having to trudge our way through all the cytoplasms and androeciums of a biology textbook. Thanks for sharing! 8)

Yes ma'am. That video is true to the workings of this little guy, here is a link to Kinesin motor protein.
http://en.wikipedia.org/wiki/Kinesin
Dynesin is the counter to Kinesin and moves the cargo in the opposite direction, otherwise they are the same. Kinesin moves things from the cell interior to it's exterior. In the positive direction while his brother/sister Dynesin moves things from the negative end to the positive end (peripheral region of the cell to it's center near the nucleus.)
You can probably youtube some video's on these guys too if you want to see them in action some more or if you're interested in more detail about them!

You know Alex, seeing that and comprehending that there is this whole other world right within us, so near, but so far, as it is microscopic. So when I can realize this other complicated 'realm' that I can't see, it makes me think how much greater the spiritual realm must be, that we can not see either. I mean there is so much in that video that is going on right under our noses, that we have no idea about, not really, so it is with the spiritual realm, to a much greater degree though I think.
mercy, peace and love

Size is the greatest barrier to the physical world, what if we are just a part of a cell in something else's body?
