That’s why they shimmer with metallic greens and blues. Scientists study them to create color-changing materials and sensors that don’t fade with time. Nature basically discovered nanotechnology long before humans did. Even a tiny insect’s wing can outsmart modern engineering. #Nature #Science #Biology #Tech #In
