Spider Silk May One Day Be Produced From Bacteria
2012-07-19 10:11:02

Brett Smith for redOrbit.com - Your Universe Online In a development that could have wide reaching ramification for material production, researchers may have finally unlocked a consistent process for producing spider silk from bacteria. A new video article in JoVE, the Journal of Visualized Experiments, demonstrates a key step in the procedures to harvest and process synthetic spider silk from bacteria called “post-spin.” In this step, silk molecules are mechanically...

The Amazing Properties Of Spider Silk
2012-03-06 05:49:20

New research has revealed that spider silk carries amazing physical properties, according to a new paper published in the journal Advanced Materials. Xinwei Wang, who wanted to take a closer look at spider webs, ordered eight Nephila clavipes, commonly known as golden silk orbweavers. He put them to work eating crickets and spinning webs so their materials and habits could be studied. Wang, who is an associate profess of mechanical engineering at Iowa State University studies thermal...

Cave Spider Has Most Stretchable Silk
2012-02-10 04:37:31

The egg sac silk of the cocoon stalk of the cave spider Meta menardi is the most stretchable egg sac silk yet tested, according to a study published Feb. 8 in the open access journal PLoS ONE. Spider silk is of broad interest for its strength, extensibility and toughness and possible applications for material science and biomechanical engineering, and there are many different types of silk from many different spider species. In the current study, the authors, led by Nicola Pugno of...

Scientists Search For Spider Web's  Strength

Scientists report that they have solved the riddle of how spider webs can withstand different levels of stress - including hurricane force winds - without collapsing. Researchers, led by Markus Buehler of the Massachusetts Institute of Technology (MIT), used computer simulations to find out how silk structures respond to different levels of stress. What they found was quite remarkable. Reporting in the journal Nature, the researchers found that web durability does not only rely on silk...

Super Silk From Genetically Modified Silk Worms

US researchers say they have created genetically modified (GM) silkworms that spin silk far stronger and more elastic than the normal silk produced by the critter. Scientists from University of Wyoming, who published their research in the PNAS journal, say their ultimate goal is to produce silk from worms that has the toughness of spider silk. Spider silk, weight-for-weight, is stronger than steel. The team say the silkworm silk has a whole range of biomedical applications, including uses...

Researchers have shown for the first time how Golden orb web spiders (Nephila antipodiana) add a chemical to their web silk to repel invading ants. The finding adds a chemical defense to the impressive properties of spider silk, already known to be very strong, elastic and adhesive, and may provide new opportunities for pesticide design. The study was led by researchers from the National University of Singapore (NUS) and the University of Melbourne, and is published in the journal...

A new episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast series spins a real-life tale in which spider silk shows promise for overcoming a major barrier to the use of gene therapy in everyday medicine. The new installment from the world's largest scientific society explains in non-technical language that gene therapy involves the use of beneficial genes to prevent or treat disease. It requires safe and efficient carriers or...

Strand for strand no fabric can compare to the luxurious feel, luminosity and sheen of pure silk. Since millennia, the Chinese have been unraveling the cocoons of the silk worm (Bombyx mori) and weaving the fibers into sumptuous garments, hangings, carpets, tapestries and even artworks of painted silk. Now, for the first time, scientists at the Smithsonian's Museum Conservation Institute have developed a fast and reliable method to date silk. This new technique, which is based on capillary...

"The strength of spider dragline silk exceeds that of any material produced in laboratories, by far. All attempts to manufacture threads of similar strength have failed thus far," explains Professor Horst Kessler, Carl von Linde Professor at the Institute for Advanced Study at the TU Muenchen (TUM-IAS). In collaboration with the workgroup of Prof. Thomas Scheibel, who was a researcher at the TU Muenchen until 2007 and who now holds a chair of the Institute of Biomaterials at the Universitaet...

Genetically engineered spider silk could help overcome a major barrier to the use of gene therapy in everyday medicine, according to a new study that reported development and successful initial laboratory tests of such a material. It appears in ACS' journal Bioconjugate Chemistry. David Kaplan and colleagues note that gene therapy "” the use of beneficial genes to prevent or treat disease "” requires safe and efficient carriers or "vectors." Those carriers are the counterparts to...

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...
