“The squid’s ability to rapidly and reversibly transition from transparent to colored is remarkable,” said study co-author Alon Gorodetsky, associate professor of chemical and biomolecular engineering at UC Irvine. “We found that cells containing specialized subcellular columnar structures with sinusoidal refractive index distributions enable the squid to achieve such feats.” … Building on those insights, the researchers described in Science how they engineered a flexible composite that mimics and extends the squid’s optical range.
