Caption: C. David Williams created a 3-D computer model of filaments of myosin (in red) reaching out and tugging along filaments of actin (in blue, looking like stands of pearls twined together) during the contraction of a muscle. The model allowed researchers to consider the geometry and physics at work on the filaments when a muscle bulges.
