At RMIT University, researchers have found in sound itself an answer to one of manufacturing's quieter dilemmas: how to protect fragile things without harming them in the act of protection. By harnessing high-frequency acoustic waves to assemble a UV-blocking coating at room temperature, the team demonstrated that even living plant leaves could be shielded for months without interrupting their growth or photosynthesis. It is a reminder that the gentlest solutions are sometimes the most powerful — and that the boundary between the biological and the industrial may be more permeable than we assu
