orb weaver spider genetics
2014-07-21 03:30:56

Harvard University Largest-ever study of spider genetics shows orb weaver spiders do not share common origins For decades, the story of spider evolution went like this: As insects became more and more diverse, with some species taking to the skies, spiders evolved new hunting strategies, including the ability to weave orb-shaped webs to trap their prey. From that single origin, the story goes, orb-weaver spiders diverged along different evolutionary paths, leading to today, where...

Specialized Leg Organs Help Spiders Glean Information From Their Silk
2014-06-03 11:11:12

Brett Smith for redOrbit.com - Your Universe Online A spider’s web is more than just a home or trap for unsuspecting prey, it’s also a communications network capable of telling a spider information about prey, mates, and its own structural integrity. According to a new report in the journal Advanced Materials, spider silk can be tuned to a wide range of harmonics and these various frequencies provide a wealth of information to spiders, which sense the frequencies using leg organs...

April Flowers for redOrbit.com - Your Universe Online Whether you think they are creepy and scary, or useful and beautiful, one has to admit that spiders are also fascinating. And it isn't just Hollywood that finds spiders irresistible - research scientists find them equally alluring. A group of researchers from the University of Akron (UA), for example, have just released a new study demonstrating a more efficient and stronger commercial and biomedical adhesive inspired by spider silk....

University of Guelph researchers have unraveled some of the inner workings of slime produced by one of nature's most bizarre creatures – hagfish. They've learned how the super-strong and mega-long protein threads secreted by the eel-like animals are organized at the cellular level. Their research was published today in the science journal Nature Communications. The slime-making process has fascinated and perplexed biologists for more than 100 years, says lead author Prof. Douglas...

Synthetic Spider Silk Has Superhero Strength
2014-03-06 12:43:18

American Chemical Society Spider silk of fantastical, superhero strength is finally speeding toward commercial reality — at least a synthetic version of it is. The material, which is five times stronger than steel, could be used in products from bulletproof vests to medical implants, according to an article in Chemical & Engineering News (C&EN). C&EN is the weekly news magazine of the American Chemical Society. Alex Scott, a senior editor at C&EN, notes that spider...

Spider Web Not Good Heat Conductor
2014-01-22 13:54:55

[ Watch the Video: Science Showdown Over Spider Silk ] Lee Rannals for redOrbit.com - Your Universe Online A new study conducted by researchers from the University of the Basque Country brings into question the results of a 2012 study that found that spider silk conducts heat as well as metal. Two years ago Iowa State University scientists found that spider silk was not only a great heat conductor, but that the silk was just as good of a heat conductor as metal. However, the team...

Spider Omnivore Eats Pollen
2013-12-18 11:24:48

[ Watch the Video: Pollen On The Menu For Orb-Weaver Spiders ] Brett Smith for redOrbit.com - Your Universe Online Spiders have long been thought of as creepy-crawly predators, but a new study from a couple of European researchers has found that these arachnids will munch on pollen from time to time as well. According to their report in the journal PLOS ONE, the study team found that the diet of younger, common orb-weaver spiders includes around 25 percent pollen. The spiders were...

Day In The Life Of Progradungula Otwayensis
2013-09-25 11:54:31

Pensoft Publishers A recent paper published in the open access journal Zookeys provides a first-time glimpse in the natural history of the enigmatic spider species Progradungula otwayensis. Lurking in the hollows of old myrtle beech trees and thus hard to collect, this extraordinary spider is an endemic species confined strictly to the beautiful Great Otway National Park (Victoria, Australia). P. otwayensis belongs to the small spider family Gradungulidae which consists of seven genera...

Spider Web Attracted To Charged Insects
2013-07-05 10:17:49

[ Watch the Video: Falling Insects Electrostatically Deform Web ] Michael Harper for redOrbit.com - Your Universe Online A new study from the University of California claims spider webs don't attract the prey; rather, the prey attracts the web. As insects such as aphids or bees fly through the air, carried by their tiny and quickly beating wings, they build up a positive electrostatic charge. This charge may be enough to attract the thin and flexible strands of spider's silk which...

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 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...
