Marine Worm's Jaws Say 'Cutting-edge New Aerospace Materials'Posted: 5 months ago by bjk1903 Researchers in California and New Hampshire report the first detailed characterization of the protein composition of the hard, fang-like jaws of a common marine worm. Their work could lead to the design of a new class of super-strong, lightweight materials for use as construction and repair materials for spacecraft, airplanes, and other applications.
