Major hat-tip to Michael Vassar for the pointer to this excellent, inspiring, fascinating animation of molecular processes in a cell.
The animation shows a number of molecular machines--ribosomes, motors, and more--working to move molecules and structures around a cell, and even to create the structures. It also shows a lot of membrane events, and molecules working with and through membranes, and a few organelles. It shows the molecules in their real molecular structure--these are renderings of experimental data, not artists' conceptions.
Not being a poet, I can't describe how fascinating and beautiful the animation is. You have to see for yourself. I will say that I was literally ooh-ing and ah-ing while I watched it.
There is one major departure from reality: The molecules go directly to their destination, rather than bumping around randomly until they happen to fall into place. Likewise, the vast majority of molecules floating around waiting to find a place are not shown. This makes the molecular events look more deterministic and machine-like than they really are. But if they showed every molecule and all the Brownian action, it would be like trying to see through a blizzard, and there would be no way to match the molecular and cellular time scales.
An assignment, "Describe this video in as much detail as possible," would make a challenging final exam question for even a college-level cellular biology or molecular biology class. I could write ten pages easily, and I only recognized about half of what was going on.
As computers speed up and software improves, it will rapidly become easier to make this kind of video. The pedagogical implications are huge. A few geniuses may have been able to "see" the molecular level this way in their imagination. Now, students will be able to see it.
There's a saying that "The medium is the message." The message of this medium is: The nanoscale is accessible.
