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...

Researchers have discovered a male spider in the Judean foothills of Israel with an evolutionarily effective yet sadistic sexual perversion. For most spiders, the mating ritual involves the male ejecting sperm into the female's vulva, where it is stored it in a pouch called the spermatheca. These receptacles give the female control of when her eggs will be fertilized, by moving sperm onto them before she lays. The spermatheca is a "last in, first out" structure which means that the last male...

Scientists have strengthened spider silk three times more than its natural durability - which is already tougher and lighter than steel - by infusing the silk with small bits of metal, Reuters reported. This procedure may prove beneficial for developing extremely durable textiles as well as high-tech medical materials like artificial bones and tendons. Researcher Seung-Mo Lee of the Max Planck Institute of Microstructure Physics in Halle, Germany suggested the infused spider silk "could make...

A researcher at the University of Kansas has discovered a link between ancient spiders and their modern relatives. Scientists have often debated about the origin of the silk spiders use to spin webs, said Paul Selden, director of the Paleontological Institute at the Biodiversity Institute and professor of invertebrate paleontology at Kansas University. Selden discovered that what researchers had previously considered to have been web-spinning appendages located on the fossilized remains of...

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...
