Mussels cling to rocks using thread-like tentacles.

BACKGROUND: Researchers have developed a new group of adhesives for wood products inspired by the ability of mussels to cling to rocks using thread-like tentacles. These threads are proteins that retain powerful adhesive properties even in water. By adding these amino acids to more common proteins, like soy flour, the scientists have produced new wood adhesives. The researchers are also exploring ways to create new adhesives from tree bark or decayed wood.
ADVANTAGES: The new wood adhesives are natural and environmentally friendly, unlike the formaldehyde-based adhesives currently used to make some wood products, especially plywood, particleboard, and laminated veneers. They are also stronger and more water resistant.
USES: The new glue is being used to make environmentally friendly particle board-the main wood used to make kitchen cabinets and other wood products. They may replace the formaldehyde-based wood adhesives currently used to make some wood composite products such as plywood, particleboard, and laminated veneer lumber products.
WHERE IT'S BEING SOLD:Columbia Forest Products of Portland, the nation's largest producer of decorative plywood, has exclusive rights to use it in plywood.
WHAT IS BIOMIMICRY?Biomimicry is a field in which scientists, engineers, and even architects study models and concepts found in nature, and try to use them to design new technologies. Here are some well-known examples of biomimicry:
Velcro was inspired by cockleburs, which cling tenaciously to clothing and animal fur.
The design for the Eastgate Building in Harare, Zimbabwe -- the country’s largest commercial and shopping complex -- is based on the region’s termite mounds.
Both Leonardo da Vinci and the Wright brothers studied the flight of birds when designing their flying machines.
Alexander Graham Bell designed his telephone receiver around the principles of the human ear.
Sonar was inspired by how whales, dolphins and bats emit high-pitched sounds and analyze the returning echoes to help them navigate.
