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.

This is an image from another movie called DICER, about the eponymous enzyme which is responsible for clipping little pieces of RNA off of bigger chunks. Here you can see that it's about to clip off the chunk of RNA that it's clinging to. The little pieces of RNA help maintain proper levels of protein in your blood. What's amazing is that this toothpaste-looking chunk of enzyme is actually an incredibly precise instrument, only scissoring off the exact right amount of RNA that your body needs.
