How Do Spiders Spin Silk?
2014-08-07 03:51:02

PLOS Spider silk is an impressive material; lightweight and stretchy yet stronger than steel. But the challenge that spiders face to produce this substance is even more formidable. Silk proteins, called spidroins, must convert from a soluble form to solid fibers at ambient temperatures, with water as a solvent, and at high speed. How do spiders achieve this astounding feat? In new research publishing in the open access journal PLOS Biology on August 5, Anna Rising and Jan Johansson show...

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

[ 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...

Fascinating Examples Of Genetic Engineering

Rayshell Clapper for redOrbit.com - Your Universe Online After learning about human genetic engineering, many readers might want to find out about some examples of genetic engineering. Both bizarre and beneficial, the following article highlights some truly fascinating and pragmatic examples of modern genetic engineering. The Biotechnology Forums, a website for professionals and students in biotechnology (the area that studies genetic engineering) recently explained some of these...

Bio-Inspired Materials Leading To Greater Engineering
2013-02-16 10:56:29

Lee Rannals for redOrbit.com — Your Universe Online Bio-inspired, man-made materials may one day offer up designs that are more lightweight, tougher, and stronger than other options out there. A team writing in the journal Science say they have identified characteristics of biological materials they think engineers will be able to emulate in future materials. Two engineers at the University of California, San Diego examined three characteristics of biological materials, including...

Researcher and team are the first to measure all of the elastic properties of an intact spider's web, drawing a remarkable picture of the behavior of one of nature´s most intriguing structures. The work could lead to new “bio-inspired” materials that improve upon nature. As fibers go, there´s never been anything quite like spider silk. Stretch it. Bend it. Soak it. Dry it out. Spider silk holds up. It is five times stronger than steel and can expand nearly a third...

Understanding The Mysteries Of Spider Silk
2013-01-28 19:02:43

Lee Rannals for redOrbit.com — Your Universe Online Scientists are unraveling the mysteries of what makes the fiber that spiders spin five times as strong as piano wire. A team from Arizona State University found a way to obtain a wide variety of elastic properties of the silk from several spiders' webs using non-invasive laser light scattering techniques. "Spider silk has a unique combination of mechanical strength and elasticity that make it one of the toughest materials we...

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...

Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
