Researchers at Florida Polytechnic University and Youngstown State University have made a groundbreaking discovery about peacocks’ iridescent feathers, finding that the eyespots contain nanostructures that can emit yellow-green lasers. By analyzing the unique properties of these structures, scientists hope to develop biological lasers or create new tools for analyzing living materials. This innovative research was published in Scientific Reports and challenges our understanding of how animals display colors and patterns.
