Dust is a fascinating substance. Our bodies are always shedding dust from our skin, hair, and nails, leaving little bits of DNA wherever we roam. Dust floats unseen through the air around us. It's light. It's hard to see unless it lands on a contrasting surface or crosses the path of a ray of sunshine. It can travel far and wide.
