Below the fold is a video of cellular vesicles "walking" along microtubules inside a cell. I thought that the assembly of the microtubules was especially interesting to watch, particularly since my students often could not understand the dynamics of this process.

OK this post was a warm up for today.
The Cytoskeleton. Now that's what you call a misnomer. It is one of the most fascinating, yet misunderstood, macromolecular assemblies of the cell.
There's a new paper in Dev Cell with a nice reconstruction of a fission yeast cell (S. pombe) with all its microtubules.
From the abstract:
In this day, some biologist have to move beyond the simplistic view that the cell is a bag of M&Ms. What do I mean by that? It's the idea that enzymes and organelles are free floating entities within the cell.
This I thuroughly enjoyed! Thanks for posting. :o)
