Spiders In Space Weave A Web Of Scientific Knowledge
2014-04-24 03:44:31

Laura Niles, NASA While spiders were busy spinning webs in space, researchers on Earth weaved their knowledge of this activity into educational materials to inspire and motivate students. Now, this free, Web-based guide is being re-released through Scholastic and Sony Pictures as curriculum for educators to leap on the excitement surrounding the release of the film, “The Amazing Spider-Man 2.” For those who may have missed it, this guide’s inspiration came from real science using...

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...

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...

Mating Plugs Produced By Female Spiders To Prevent Unwanted Sex From Males
2012-08-05 10:30:36

redOrbit Staff & Wire Reports - Your Universe Online A new mechanism of animal mating plug production has been discovered by scientists at the Smithsonian and their colleagues. In the giant wood spider (Nephila pilipes), which is a highly sexually dimorphic and polygamous species, many small males will compete with each other for their chance with a few large females. These males have been known to sever their own genitals during mating in order to plug the female, gain paternity and...

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...

Scientists Search For Spider Web's  Strength
2012-02-02 09:38:05

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...

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 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...

By Jessica Nimon, International Space Station Program Science Office, NASA's Johnson Space Center The very idea of spiders in space brings to mind campy, black and white horror films involving eight-legged monsters. In actuality, it is a scientific investigation called Commercial Generic Bioprocessing Apparatus Science Insert-05 or CSI-05, in which researchers observe arachnid habits in a microgravity environment. This is the second spider investigation on the International Space...

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...

The Joro Spider (Nephila clavata) is a species of arachnid that is a member of the golden orb-web spider group. It is found in Japan (except Hokkaidō), Korea, Taiwan and China. The web of the female can reach up to 39 inches in width. The yellow threads appear rich gold in sunlight. The web has three layers: the central orb, plus two irregular layers in front of and behind the orb. The adult female is about 1 inch. The male is much smaller and is no bigger than 0.4 inches. The female...
