Biological complexity: watch as cellular elements move (Introduction)

Amazing videos looking at the elements of cells move about as they work:

"Light microscopy makes it simple to identify specific cellular structures by tagging them with easy-to-see fluorescent molecules. With the development of super-resolution (SR) fluorescence microscopy, these structures can be viewed with even greater clarity. But fluorescence can reveal only a few of the more than 10,000 proteins in a cell at a given time, making it difficult to understand how these few relate to everything else. Electron microscopy (EM), on the other hand, reveals all cellular structures in high-resolution pictures—but delineating one feature from all others by EM alone can be difficult because the space inside of cells is so crowded.

"Combining the two techniques gives scientists a clear picture of how specific cellular features relate to their surroundings, says Harald Hess, a senior group leader at the Howard Hughes Medical Institute's Janelia Research Campus. "This is a very powerful method.'"

Comment: Nothing more to abstract except the videos, which I could move here, but its easier to look at the original site. These units act as if they know what they are doing. They don't. Be amazed at how living cells look at work. Never by chance.
