To Build Better Fiber Optic Cables, Ask a Clam
New research led by scientists at Duke University, in collaboration with Stanford University, reveals that natural systems in the shells of heart cockles, a type of marine mollusk, mimic fiber optic cables. The study, spearheaded by Duke biologist Sönke Johnsen and former NSF PRFB Fellow Dakota McCoy, uncovered how translucent areas in the clams' shells channel specific wavelengths of light to nourish symbiotic algae. This unique adaptation allows the algae to photosynthesize without exposing the clams to predators, functioning as natural skylights that filter and focus light. Duke's cutting-edge use of advanced microscopy and computer simulations has not only unveiled this fascinating natural phenomenon but also opened up exciting possibilities for future innovations in fiber optic technology, particularly in enhancing light transmission over long distances and around curves.
