Macrophages Squirming Along the Outside of Your Capillaries

This gorgeous, strange image is a highly-accurate visualization of what's happening inside your body right now. Macrophages, specialized cells that help keep your body in good repair by cleaning up debris, zoom around your capillaries, among other places. In this image, we've left the macrophages behind and are inside a cell watching proteins walk around on tethers to carry proteins or other materials elsewhere in the cell. This is actually a still from an amazing flick called "Inner Life of the Cell," made for biology students, and currently on display at a new show in New York called Design and the Elastic Mind.
