Inside your body, proteins are a kind of communications system, allowing DNA to pass information and energy back and forth. Every protein is a specific message from one molecule to another. And the information is expressed via the strange folds and twists of each protein's structure. They look like beautifully folded ribbons, and you can gaze at their sublime spirals on the Beautiful Proteins blog, created by Mike Tyka. This is microbiological fetishism at its finest.
