A spectacular golden textile, conceived and created by Simon Peers and Nicholas Godley in Madagascar from silk thread collected from over one million Golden Orb spiders (Nephila madagascariensis), will go on exhibit at the Art Institute of Chicago, the country's second largest art museum. On special loan to the museum from Mssrs. Peers and Godley as part of the inaugural celebration of the museum's new galleries devoted to African art and Indian art of the Americas, the Spider Silk textile...

ST. LOUIS, April 12, 2011 /PRNewswire/ -- Sigma Life Science, the innovative biological products and services research business of Sigma-Aldrich® (Nasdaq: SIAL), today announced the signing of an agreement with Kraig Biocraft Laboratories, Inc. (KBLB) to develop genetically modified silkworms for the production of spider silk, using Sigma's proprietary CompoZr Zinc Finger Nuclease (ZFN) technology. The transfer of silk genes from the spider to the silkworm is expected to...

Scientists now have a better understanding of why spider silk fibers are so incredibly strong. Recent research, published by Cell Press on February 15th in Biophysical Journal, describes the architecture of silk fibers from the atomic level up and reveals new information about the molecular structure that underlies the amazing mechanical characteristics of this fascinating natural material. Spiders spin silk, which is remarkably strong and stretchy, to use in webs and to suspend themselves....

Studying spider silk, NSF-supported researchers learn about the properties of this sticky material, and their findings could lead to new bio-adhesives and glues that work under water Ali Dhinojwala and Vasav Sahni consider themselves materials scientists, not biologists. They study surfaces, friction and adhesion. Nevertheless, they have discovered that understanding how nature makes things stick sometimes means getting up close and personal with the creatures responsible. When they...

A research and development effort by the University of Notre Dame, the University of Wyoming, and Kraig Biocraft Laboratories, Inc. has succeeded in producing transgenic silkworms capable of spinning artificial spider silks. "This research represents a significant breakthrough in the development of superior silk fibers for both medical and non-medical applications," said Malcolm J. Fraser Jr., a Notre Dame professor of biological sciences. "The generation of silk fibers having the properties...

Researchers have long envied spiders' ability to manufacture silk that is light-weighted while as strong and tough as steel or Kevlar. Indeed, finer than human hair, five times stronger by weight than steel, and three times tougher than the top quality man-made fiber Kevlar, spider dragline silk is an ideal material for numerous applications. Suggested industrial applications have ranged from parachute cords and protective clothing to composite materials in aircrafts. Also, many biomedical...

Discovery opens the way toward biomimetic production of ultra-strong, elastic fibers Five times the tensile strength of steel and triple that of the currently best synthetic fibers: Spider silk is a fascinating material. But no one has thus far succeeded in producing the super fibers synthetically. How do spiders form long, highly stable and elastic fibers from the spider silk proteins stored in the silk gland within split seconds? Scientists from the Technische Universitaet Muenchen (TUM)...

CSIRO scientist Dr Tara Sutherland and her team have achieved another important milestone in the international quest to artificially produce insect silk. They have hand-drawn fine threads of honeybee silk from a "Ëœsoup' of silk proteins that they had produced transgenically. These threads were as strong as threads drawn from the honeybee silk gland, a significant step towards development of coiled coil silk biomaterials. "It means that we can now seriously consider the uses to...

A spider may be the reason fog-catching nets, which provide precious water in rain-starved parts of the world, may be ready for a high-tech upgrade. Chinese scientists reported their research in the journal Nature on why spider's silk is not only famous for strength but also terrific for collecting water from the air, sparing the creature the hunt for a drink. The secret lies in the silk's tail-shaped protein fibers that change structure in response to water. The tiny section of thread...

Scientists have strengthened spider silk three times more than its natural durability - which is already tougher and lighter than steel - by infusing the silk with small bits of metal, Reuters reported. This procedure may prove beneficial for developing extremely durable textiles as well as high-tech medical materials like artificial bones and tendons. Researcher Seung-Mo Lee of the Max Planck Institute of Microstructure Physics in Halle, Germany suggested the infused spider silk "could make...

The Edible Golden Silk Spider (Nephila edulis) also known as the Golden Silk Orb-weaver, is a species of spider that occurs widely in Australia in both tropical and temperate regions. It is also found in parts of New Guinea and New Caledonia. It is not understood why this particular species is considered edible, however, it is a delicacy in New Guinea, where it is plucked from the web and lightly roasted over open fire. The species was first collected in 1799 byJacques Labillardiere, in...

The Golden Silk Spider (Nephila clavipes) is a species of orbweaver spider. It is found in the warmer regions of the Americas. In the United States, this species ranges throughout the coastal southeast and inland, from North Carolina to Texas. In many areas its distribution is somewhat localized and may be absent in many areas over wide areas. In some arboreal or swampy areas, adults and their webs can be found in large concentrations, especially near the coast. This species is also...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
