Summary:
Researchers have reported 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.

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. 

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.

Algonquin Power Goes Activist on Its Target Gas Natural

TheStreet (July 23, 2014) — When The Deal's Amanda Levin exclusively reported that Gas Natural had been talking to potential suitors, the Ohio company responded with a flat denial, claiming its board had not talked to anyone about a possible sale. Lo and behold, Canadian utility Algonquin Power and Utilities not only had approached the company, but it did it three times. Its last offer was for $13 per share as Gas Natural's was trading at a 60-day moving average of about $12.50 per share. Now Algonquin, which has a 4.9% stake in Gas Natural, has taken its case to shareholders, calling on them to back its proposals or, possibly, a change in the target's board.
