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...

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...

Amber Catches 100 Million-year-old Spider Attack
2012-10-09 04:32:07

April Flowers for redOrbit.com - Your Universe Online Researchers at Oregon State University have found an extraordinarily rare fossil. Trapped in amber is what the research team describes as the only example of a spider attack on prey caught in its web — a 100 million year old snapshot of an engagement frozen in time. Found in the Hukawng Valley of Nyanmar, the fossil dates from the Cretaceous between 97 and 100 million years ago. Giving some evidence to oldest examples of spider...

Orb Weaver Spider Builds Intricate UV-Decorated Webs To Attract Insects
2012-09-20 10:29:19

Lawrence LeBlond for redOrbit.com - Your Universe Online The ultraviolet decorations and intricate patterns of the orb-weaver spider´s web is used to attract food, say scientists from the University of Incheon, whose studies of a common orb-weaver spider species are published in the journal Behavioral Ecology and Sociobiology. Researchers suggest that the UV light-reflecting patterns seen in the webs of orb-weavers, particularly the Wasp Spider, could trick flying insects into...

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...

According to new research published in the journal Naturwissenschaften, spiders do not stick to their own webs because of the way they move. The spiders ability to not stick to its own web was originally attributed to a special coating on their legs. However, researchers at the Smithsonian Tropical Research Institute and University of Costa Rica used modern imaging technology to record close-up footage that better explains the ability. The team combined a video camera and a...

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...

Why Don't Spiders Stick To Their Own Webs?
2012-03-02 04:00:37

[ Video 1 ] | [ Video 2 ] Researchers at the Smithsonian Tropical Research Institute and University of Costa Rica asked why spiders do not stick to their own sticky webs. Repeating old, widely quoted but poorly documented studies with modern equipment and techniques, they discovered that spiders' legs are protected by a covering of branching hairs and by a non-stick chemical coating. Their results are published online in the journal, Naturwissenschaften. They also observed that spiders...

Southern House Spider, Kukulcania hibernalis
2014-04-08 10:12:47

The Southern House Spider (Kukulcania hibernalis) is a species of large North American spider which display strong sexual dimorphism. The males may be mistaken for the Brown Recluse due to the similar coloration and body structure. However, compared to the Brown Recluse, male Southern House Spiders are usually larger in size, lack the distinctive violin shape on their cephalothorax, and have abnormally long and slender pedipalps. The females are a dark brown or black color and more compact....

The Triangulate Cobweb Spider (Steatoda triangulosa), also known as the Triangulate Bud Spider, is a species of common house spider that is found throughout the world. It is found along the coasts in North America, in southern Russia, in New Zealand, and in Europe. It is largely believed to be native to Eurasia. This spider is well known for the triangle-shaped pattern on the upper side of its abdomen. The adult female is 0.13 to 0.25 inches long. It has a brown-orange cephalothorax...

The Daddy-long-legs Spider (Pholcus phalangioides), also known as the Cellar Spider or Skull Spider, is a species of arachnid found in many parts of the world, but originally came from the tropics. They are commonly found living in caves, garages, ceilings of household rooms, and cellars. In Australia, it is considered a beneficial species as it kills and eats the venomous redback Spider. There is some confusion with the common name "daddy longlegs". This name is also applied to two other...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
