Harvard biologist worked with animators to create this animation of aspects of cellular function. Golly, we're all so busy on a cellular level, no wonder we get tired!
The complexity is mind-boggling. THIS is why I'm so frantic to learn this stuff. I love the bit with zipper-like action of the microtubules-- looks like a knitted tube, or an Ndebele-style woven tube of beads -- really cool!
I'm pretty sure some Mitochondria made appearances in Ghostbusters, too.
