Iridescent beetle coat acts like liquid crystal

Scientists at the Georgia Institute of Technology in Atlanta recently discovered jewel beetles change color because of the light-reflecting properties of the cells that make up their external skeletons, not because of unique, light-absorbing properties in their pigment. They say the finding could be important for industries such as car manufacturers that look to reflective light paints for automobiles.

The journal Science reports the finding in its July 24 issue. The National Science Foundation supports the research.

I think the jewel beetle art you did is absolutely stunning. I could not wait to use it in Science 360. It really has the wow factor. Maybe it’s the colors but I just love it.
