"Spider silk is often touted as some of the strongest material on Earth: According to some calculations, it can be up to five times stronger than steel cable of similar weight—though that comparison is not perfect. If humans could manufacture spider silk on an industrial scale, which they’ve been trying to do for decades, it could lead to an era of lightweight bulletproof vests, helmets, superstrong threads and patches that could be used during surgery and even lightweight airplane fuselages."
Spiders are air-breathing arthropods that have eight limbs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except Antarctica, and have become established in nearly every land habitat. As of January
"Spiders cant fly, but they can naturally paraglide. Their ability is known as ballooning, and scientists have now shown that it extends further than windy thermals. Electric fields are strong enough to trigger ballooning even when theres no wind."
Spiders"He thought about spiders, twisting thread into beautiful symmetry, taming chaos with ordered nets that greeted the dawn, hung with globes of dew that caught and held cores of sunlight, and tiny images of the world."
Spiders"Spiders were around long before humans, and it is likely they will be around in some number far into the future, even if humans are not. When most land and sea animals died out during the Permian mass extinction, spiders survived. Spiders thrived when oxygen levels were both lower and higher than today, when the sunlight hitting the ground was both stronger and weaker, and when plant and animal populations were both greater and smaller. Silk and the evolvable nature of the genes that dictate it have enabled spiders to stake a claim on the land for hundreds of millions of years and they are likely to do so for hundreds of millions of years to come."
Spiders"Ive lately had two spiders Crawling upon my startled hopes— Now though thy friendly hand has brushed em from me, Yet still they crawl offensive to mine eyes: I would have some kind friend to tread upon em."
Spiders"In their latest study in the journal ACS Macro Letters, the team found that instead of being one long strand of protein, the ribbon of silk is composed entirely of 1 micron-long nanostrands stuck together in parallel. Typically, about 2,500 of these mini-strands clung together to form one strand of silk. “We were expecting to find that the fiber was a single mass,” co-author Hannes Schniepp of William & Mary says in a statement. “But what we found was that the silk was actually a kind of tiny cable.”"
Spiders"“There might be spiders,” said Jacqueline. She wrinkled her nose, less out of actual distaste and more out of the knowledge that she was supposed to find spiders distasteful. She really found them rather endearing. They are sleek and clean and elegant, and when their webs got messed up, they ripped them down and started over again. People could learn a lot from spiders."
