>Cells are extremely crowded

Thanks for the excellent blog post. This is something more people need to appreciate.

I never realized just how crowded until I saw David Goodsell's molecular illustrations[1] in Drew Barry's TED talk.[2] Goodsell's drawings show the actual density and diversity of molecules inside the cell.
