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...

A fossilized spider, uncovered in inner Mongolia, is thought to be the largest ever spider fossil discovered. It has been so perfectly preserved from 165 million years ago that scientists have identified it down to the exact species and that is was an adult female, BBC News reports. This specimen was uncovered from at a site called Daohugou in Inner Mongolia, also home to areas filled with fossilized salamanders, small primitive mammals, insects and water crustaceans. This fossilized Golden...

Studying spider silk, NSF-supported researchers learn about the properties of this sticky material, and their findings could lead to new bio-adhesives and glues that work under water Ali Dhinojwala and Vasav Sahni consider themselves materials scientists, not biologists. They study surfaces, friction and adhesion. Nevertheless, they have discovered that understanding how nature makes things stick sometimes means getting up close and personal with the creatures responsible. When they...

Scientists have confirmed that spider webs discovered in Britain are the oldest on record, dating back 140 million years to the Cretaceous period. The webs, which were enclosed in amber, were discovered on a beach in East Sussex by fossil hunter Jamie Hiscocks and his brother Jonathan. Professor Martin Brasier, a paleobiologist at the Oxford University, said the fossils were the earliest spider webs ever to be entered into the fossil record. "This amber is very rare. It comes from the very...

Researchers from the United States and Slovenia have discovered a new, giant Nephila species (golden orb weaver spider) from Africa and Madagascar and have published their findings in the Oct. 21 issue of the journal PLoS ONE. MatjaÃ…¾ Kuntner, chair of the Institute of Biology of the Slovenian Academy of Sciences and Arts and a Smithsonian research associate, along with Jonathan Coddington, senior scientist and curator of arachnids and myriapods in the Department of...

Aboard the International Space Station, spiders are living as an educational project and they seem to have gotten the hang of weightlessness. Their first orbital webs were messy.  However, a week into their flight, televised images were sent back to Earth to show their progress. "We noticed the spider made a symmetrical web," space station commander Mike Fincke told ground controllers on Friday. "We're really amazed that the spider could adapt to space so quickly." The spider video...

A sneaky spider has been named in honor of rock musician Neil Young. Jason Bond, a biologist at East Carolina University, named a newly discovered arachnid, Myrmekiaphila neilyoungi. It is also known as a trapdoor spider. "There are rather strict rules about how you name new species," Bond said. "As long as these rules are followed you can give a new species just about any name you please." He added, "With regards to Neil Young, I really enjoy his music and have had a...

A German team of engineers reported developing a device that borrows silk-spinning techniques from spiders to create strong strands with potential uses for lightweight medical equipment materials.The team said their work shed light on how spiders produce their rugged webs."We can observe the initial steps of fiber formation, which was not possible before," said Sebastian Rammensee of the Technical University of Munich and one of the authors of the Proceedings of the National Academy of...

CAMBRIDGE, Mass.-- A team of MIT engineers has identified two key physical processes that lend spider silk its unrivaled strength and durability, bringing closer to reality the long-sought goal of spinning artificial spider silk. Manufactured spider silk could be used for artificial tendons and ligaments, sutures, parachutes and bulletproof vests. But engineers have not managed to do what spiders do effortlessly. In a study published in the November issue of the Journal of Experimental...

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...

The Autumn Spider (Metellina segmentata) is a species of spider that has a Palearctic distribution and has been introduced to Canada. Adults are normally found from August to October. The preferred habitat is open wood edges or gardens. This is one of the most common orb-weaving spiders. The web of this spider has no threads at its center. Most webs are built low above the ground. The spider sits at the center during the day for long periods of time. Sometimes it will hide at the edge and...
