Light bends a speck: tiny particles change shape when a molecule flips

In a Japanese laboratory, a chain of tiny events ends with something you can see: light flips a molecule, the polymer strands around it rearrange, and a microscopic particle changes shape. The peer-reviewed study in Macromolecules maps that step-by-step path for the first time. It is basic science with a playful edge, and it points toward light-driven micro-machines and materials that respond on command.
