Bio-Inspired Materials Leading To Greater Engineering
2013-02-16 10:56:29

Lee Rannals for redOrbit.com — Your Universe Online Bio-inspired, man-made materials may one day offer up designs that are more lightweight, tougher, and stronger than other options out there. A team writing in the journal Science say they have identified characteristics of biological materials they think engineers will be able to emulate in future materials. Two engineers at the University of California, San Diego examined three characteristics of biological materials, including...

Researcher and team are the first to measure all of the elastic properties of an intact spider's web, drawing a remarkable picture of the behavior of one of nature´s most intriguing structures. The work could lead to new “bio-inspired” materials that improve upon nature. As fibers go, there´s never been anything quite like spider silk. Stretch it. Bend it. Soak it. Dry it out. Spider silk holds up. It is five times stronger than steel and can expand nearly a third...

Understanding The Mysteries Of Spider Silk
2013-01-28 19:02:43

Lee Rannals for redOrbit.com — Your Universe Online Scientists are unraveling the mysteries of what makes the fiber that spiders spin five times as strong as piano wire. A team from Arizona State University found a way to obtain a wide variety of elastic properties of the silk from several spiders' webs using non-invasive laser light scattering techniques. "Spider silk has a unique combination of mechanical strength and elasticity that make it one of the toughest materials we...

Black Widow Stowaways Make It To England
2013-01-15 10:00:58

Michael Harper for redOrbit.com — Your Universe Onlinebla In certain parts of the U.S. — Arizona, for example — black widow spiders are quite common. While this familiarity might not make them any less frightening, people in these areas are at least aware of the tiny eight-legged predators and know how to respond when they happen to cross paths with one of these potentially deadly arachnids. Recently, however, these spiders have been showing up in some very unusual...

Cyclosa Spider Hunts With Decoys
2012-12-20 20:08:07

Lee Rannals for redOrbit.com — Your Universe Online While salt licks may be one intelligent ploy by man to attract deer for hunting, its got nothing on the method used by one Amazonian arachnid. One tiny spider in the Peruvian Amazon builds an elaborate decoy spider, and hangs it from its web in order to trick predators into getting stuck in its web. The artful dodger takes it time crafting up decoys from dead insects, debris and leaves as what scientists suspect is a defense...

2012-12-20 13:14:31

Lawrence LeBlond for redOrbit.com - Your Universe Online Finding a new species of animal can be an inspiring and exhilarating experience. But can you imagine multiplying that exhilaration by 2, by 5, or by 10? What about by 33? If you are Professor Jason Bond, a trapdoor spider expert, you probably did just multiply that exhilaration by 33. That´s because the Auburn University Museum of Natural History researcher has just published a report on his discovery of 33 new trapdoor...

8 Legs And A Baby

Alan McStravick for redOrbit.com - Your Universe Online The idea of the stay-at-home-dad has been getting its legs lately. Sure, we started off with quaint 80´s comedies, like ℠Mr. Mom´ and ℠Three Men and a Baby´, but, like the subject of this article, we are slowly evolving past focusing on the hijinx and silliness of the situation and viewing the caring paternal relationship in a more real light. We have experts, pundits and private-citizens who are arguing the...

MyCleaningProducts recommended to the public the use of its non-toxic spider spray when clearing the arachnids in the houses. The company made the recommendations in its new published article. Seattle, WA (PRWEB) October 11, 2012 A spider spray can make a spider infestation either a failure or a success. Misinformation can have the same effect. And so to help homeowners implement a truly effective house spider elimination, MyCleaningProducts published a post about the top three house spider...

Harnessing Spider Silk For Use In Biosensors, Lasers And Microchips
2012-10-11 11:55:27

Researchers at Frontiers in Optics 2012 describe ways to use natural silk for implantable optics, compostable lasers, and microfibers integrated into photonic chips Spiders use their silk to catch lunch. Now physicists are using it to catch light. New research shows that natural silk could be an eco-friendly alternative to more traditional ways of manipulating light, such as through glass or plastic fiber optic cables. Two teams independently exploring possible applications for the...
