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...

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...

Male Spiders May Break Off Genitals To Boost Paternity
2012-02-01 09:13:18

Perhaps it is not a thought that crosses the minds of the average male, but spiders have more to consider than most other creatures when it comes to choosing a mate. Biologists have long known that some male spiders sacrifice their genitals in the act of reproduction and that doing so leaves them sterile, but no one could adequately explain why this was so. An answer, however, may now be at hand following a series of meticulous experiments by Daiqin Li, a behavioral ecologist at the...

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...

Decorative white silk crosses are an ingenious tactic used by orb-weaving spiders to protect their webs from damage, a new study from the University of Melbourne has revealed. The team, led by Dr Andre Walter and Professor Mark Elgar from the University of Melbourne's Department of Zoology, found that orb-weaving spiders respond to severe damage to their webs by building bigger silk crosses, but if the damage is mild they don't bother adding extra decoration. Professor Mark Elgar said web...

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...

Nephilengys borbonica is a species of spider native to Madagascar and nearby islands (the Mascarene Islands, Comoro Islands and the Seychelles). In Madagascar, this species is commonly found in houses and buildings. In Réunion, it can be found in cloud forests up to 4,900 feet. The species name borbonica refers to the island of Réunion, which was called Bourbon until 1848. The adult female grows to 0.6 to 0.95 inches long in Madagascar. The females from other neighboring islands...

The Giant Wood Spider (Nephila pilipes) is a species of arachnid that is found in Japan, China, Taiwan, Singapore, Myanmar, Sri Lanka, India, Papua New Guinea, and northern Australia. Its habitat is primary and secondary forests and gardens. The adult female grows to a length of 1.2 to 2 inches. The male only grows to about a quarter of an inch. In juvenile females, the first, second and fourth pairs of legs have dense hairy brushes. The brushes of hair disappear as the female matures....

The Red-legged Golden Orb-web Spider (Nephila inaurata) is a species of arachnid that is found in southern Africa. It also can be found on several islands in the Indian Ocean (Mauritius, Réunion, Rodrigues, and the Seychelles). There is also a second subspecies recognized: Nephila i. madagascariensis that is found from South Africa to the Seychelles. The web of this species is said to be so strong that sometimes even birds and bats can get tangled in its web. The web is often found in...

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...
