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...

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...

A research and development effort by the University of Notre Dame, the University of Wyoming, and Kraig Biocraft Laboratories, Inc. has succeeded in producing transgenic silkworms capable of spinning artificial spider silks. "This research represents a significant breakthrough in the development of superior silk fibers for both medical and non-medical applications," said Malcolm J. Fraser Jr., a Notre Dame professor of biological sciences. "The generation of silk fibers having the properties...

Researchers have long envied spiders' ability to manufacture silk that is light-weighted while as strong and tough as steel or Kevlar. Indeed, finer than human hair, five times stronger by weight than steel, and three times tougher than the top quality man-made fiber Kevlar, spider dragline silk is an ideal material for numerous applications. Suggested industrial applications have ranged from parachute cords and protective clothing to composite materials in aircrafts. Also, many biomedical...

Discovery opens the way toward biomimetic production of ultra-strong, elastic fibers Five times the tensile strength of steel and triple that of the currently best synthetic fibers: Spider silk is a fascinating material. But no one has thus far succeeded in producing the super fibers synthetically. How do spiders form long, highly stable and elastic fibers from the spider silk proteins stored in the silk gland within split seconds? Scientists from the Technische Universitaet Muenchen (TUM)...

A spider may be the reason fog-catching nets, which provide precious water in rain-starved parts of the world, may be ready for a high-tech upgrade. Chinese scientists reported their research in the journal Nature on why spider's silk is not only famous for strength but also terrific for collecting water from the air, sparing the creature the hunt for a drink. The secret lies in the silk's tail-shaped protein fibers that change structure in response to water. The tiny section of thread...

With would-be goblins and ghosts set to drape those huge fake spider webs over doorways and trees for Halloween, scientists in Wyoming are reporting on a long-standing mystery about real spider webs: It is the secret of spider web glue. The findings are an advance toward a new generation of biobased adhesives and glues "” "green" glues that replace existing petroleum-based products for a range of uses. A report on the study was published in ACS' Biomacromolecules, a monthly journal....

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...

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
