2 (Xinhua) -- European scientists have made spiders produce webs strong enough to hold a human, the Sydney Morning Herald reported Thursday. According to a research led by Nicola Pugno at Italy's University of Trento, the new web combines spider silkSpider silk is a protein fibre spun by spiders. Spiders use their silk to make webs or other structures, which function as sticky nets to catch other animals, or as nests or cocoons to protect their offspring, or to wrap up prey.https://en.wikipedia.org › wiki › Spider_silk
Spider silk has a higher tensile strength per mass unit than steel. It would easily hold many humans. It could be used for light weight construction and tons of other applications if we could produce it artificially.
Spider silk is 0.003mm in thìckness, so one sixth the weight of the equivalent steel. That works out at around 500 grammes, thats right 18oz.
In fact, in terms of tensile strength, which is the maximum amount of stress a material can endure before breaking, spider silk is five times tougher than steel. If it was converted to human size, it would be strong enough to stop a jetliner in its flightpath.
A single strand of spider silk is strong for its size and can withstand the force of an insect that flies into it. If we could somehow scale up the spider silk to be 100 times thicker (0.3 millimeters) by constructing a rope of spider silk, it would have a strength comparable a 22 gauge steel wire.
The properties of spider silk also create the possibility for bulletproof body armor. A bullet can penetrate up to 29 layers of Kevlar. But research shows spider silk to be comparatively tougher than Kevlar and stronger than steel.

Spider silk is the toughest fibre found in nature. When stretched or pulled, it can absorb more energy than steel or nylon without rupturing, and can be used to make bulletproof vests.
Pound for pound, spider silk is stronger than steel and tougher than Kevlar.
Spiders, on average can lift to eight times their body weight. This figure varies with different spider species. What is this? Many spiders such as Darwins' bark spider can lift to 170 times their weight.
Quantitatively, spider silk is five times stronger than steel of the same diameter. It has been suggested that a Boeing 747 could be stopped in flight by a single pencil-width strand and spider silk is almost as strong as Kevlar, the toughest man-made polymer.
However, researchers have now revealed the Darwin's bark spider (Caerostris darwini) has the toughest silk ever seen — more than twice as tough as any previously described silk, and more than 10 times stronger than Kevlar.
Summary: Spiders hold the market for the strongest silks but are too aggressive and territorial to be farmed. The next best alternative involves incorporating spider DNA into silkworms, an expensive and difficult-to-scale process.
Males ejaculate onto ready-made small sperm webs and then transfer their sperm to syringe-like structures on the tips of their front appendages, or palps. As courtship progresses for the male jumping spider, he will arch his body, and slink on tiptoe toward the female.
A spider's sticky web contains traces of the critter's DNA, as well as the DNA of whatever prey that was unlucky enough to get stuck in the web, according to a new study, which found that these tiny samples of DNA can be amplified and sequenced in a lab.
Well, sorry to be bearer of bad news, but it turns out that it's scientifically impossible for someone to be Spider-Man…and it has everything to do with our stupid bodies. As everyone knows, Marvel Comics' Spider-Man is able to leap and bound up walls much like a spider can.
Unfortunately, due to spiders' territorial and cannibalistic nature, their silk has been impossible to mass produce, so practical applications have yet to materialize.
Spider web is one of the strongest for its size. It's size is extremely thin (about a tenth the thickness of silkworm silk, or 0.003mm in diameter), so relative to our strength, it's still easy to break.
A bit of Artistic License – Arachnids — spider silk does shrivel quite rapidly when exposed to intense heat (so yes, a flamethrower can clear out cobwebs), but it doesn't actually burn, much less cause the pyrotechnics that people have come to expect in fiction.
Spider silk is not stronger than steel. In a review of studies on spider silk properties the strongest reported value was 1652 MPa ultimate tensile strength [1]. If you have a block of knives in your kitchen you own steel that is stronger than the strongest spider silk ever reported.
Spider webs are a traditional remedy to stop bleeding. We don't recommend using them for humans, though. They are far from sterile and would have to be collected with care to make sure you didn't collect the spider along with the web. There are a couple of other home remedies that might help.
A spider web “made of pencil-thick, spider-silk fibres can catch a fully loaded Jumbo Jet Boeing 747 with a weight of 380 tonnes,” states biotech firm Amsilk.
Removing Spider Webs Sends A Signal To Spiders
One reason they like undisturbed locations is that they don't want to go through all the work of creating a web only to have it destroyed. When you destroy a web, you send a signal to spiders that this is not a good place to build a web.
Anyone can tell you that spiders are able to trap their meals in their sticky silky webs - but there's a bit more to it than that. Spiders are actually able to conduct electricity across the surface of the web, which attracts the potential prey.
