Recently, Belgian researchers published the latest research results about the unicorn, explaining some basic principles that the strongest creature in the world can actually change the color of its shell. Scientists say that the shell structure of the unicorn fairy-"smart material" is of great value to human application.

At present, the latest three-dimensional scanning imaging technology is used to study the shell structure and morphology of Megabox, and after years of development, this technology has been able to enter the microorganism to obtain three-dimensional images. Researchers at Namur University in Belgium use this latest imaging technology to study beetle shells. The response of beetles to external light was tested by scanning electron microscope, and the interaction between light and external structure of beetles was analyzed. They tested the dry shell specimens of beetles. During the research, they found that when external light shines on the beetle's shell, its shell will automatically turn green. However, when water penetrates into the beetle's porous shell, its shell immediately produces a "conflict effect", leading to the production of black pigment.
