"Scientists Unveil Secret Behind Butterfly Wing Colors"

Researchers at the University of Sheffield and the Central Laser Facility have discovered that the protein actin is crucial in forming the vibrant colors of butterfly wings by orchestrating the arrangement of colorful structures in the scales. Using high-resolution microscopy, they observed that denser actin bundles create more reflective ridges, and altering these structures can cause colors to fade. This discovery could inspire new technologies in sensing, diagnostics, and sustainable paints. The study was published in Nature Communications.
