A Tunable Biophotonic Rainbow

摘要

A Singaporean-Swiss team has discovered a color-generation mechanism in "rainbow" weevils that could lead to future applications in fiber optics and screen displays (Small, doi: 10.1002/smll.201802328). The rainbow weevil, also known as a snout weevil or Pachyrrhynchus congestus pavonius, is a bit of a biological marvel—it's rare that a single insect can produce such a vast spectrum of colors.
