Marine worms jaws could help design cutting-edge new aerospace materials

Washington, July 15 (ANI): A new research work by scientists of the jaws of the common marine worm 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.

The research has been carried out by scientists at California and New Hampshire, who have reported the first detailed characterization of the protein composition of the hard, fang-like jaws of a common marine worm.

In the new study, Chris C. Broomell and colleagues note that Nereis virens, also known as the sandworm or ragworm, is a burrowing marine worm found in shallow waters in the North Atlantic region.

Researchers remain intrigued by the remarkable hardness of its jaws and long pincers, which rivals that of human teeth and exceed the hardness of many synthetic plastics.

But little is known about the exact chemical composition of these structures.

Broomell and colleagues collected the jaws of 1,000 worms and analyzed their protein content using high-tech instrumentation.

They found that the primary chemical in the jaws and pincers of the worm is a unique protein, named Nereis virens jaw protein-1 (Nvjp-1), which is rich in the amino acid histidine.

The researchers also characterized the chemical conditions needed for its formation, such as the presence of zinc, which could allow researchers to create synthetic versions of this super-hard, lightweight material.

According to the researchers, this material can be used in developing cutting-edge new aerospace materials. (ANI)
