Scientists Crack Silk's Secret 408

Posted by CmdrTaco from the screw-cotton dept.
AEton writes "Researchers at Tufts University have reportedly discovered the mechanism by which spidersilk is produced. Besides the obvious use as a Kevlar substitute in bulletproof vests, silk has applications in microprocessor production, nanoscale optical fiber, a and any other application requiring strength and flexbility. Scientists have long grappled with the issue of creating silk; artificial silk is inferior to the real stuff, and the spiders can't be farmed (when you put them too close together, they eat each other). The method these Tufts researchers have found makes "strong silk" production feasible; if they can make it economical, the impact on safety equipment alone makes this material a worthwhile investment."

      Perhaps the part about changing materials that are next to worthless into something valuable is what you mean by alchemy, but none of this is anything like alchemy. Atoms are not being transformed into the "diamond atom" from the carbon atom, it is still carbon, just in a different form.

      Obviously, the diamond industry has reason to worry if the fakes are indistinguishable, but I'm not sure what you're talking about a "cult-like anti-scientific religion," that is just silly.

      There is nothing wrong with economical silk- after all, how big is the industry, and are the people in it that well off right now? Silk is something with actual applications (diamonds do as well, but not as many). Science marches on and puts people out of work, but at the end of the day, they find another line of work and everyone is better off. The standard of living in the developed world has steadily increased- and most of it is because of science.

        There is a company, I believe its called gemisis, that is creating diamonds using a laser induced plasma cloud. The diamonds were taken to am inspection lab, and the only way the techs could discern them from natural diamonds was that the artificial ones were too perfect. Diamonds generated by heat and pressure in a lab have more flaws then natural, but the plasma diamonds had too little flaws. I suppose you could dope the chamber with a few minerals and come out with a diamond that was very damn hard to detect. You can read all about it in the latest Wired magazine.

      There isn't currently a spider-silk industry. There's a silk industry, but from what I understand the whole point of spider silk as opposed to silkworm silk (which is at least relatively easily harvested), is that spiders have stronger silk with many more applications. So realistically, what we have here is not one industry "ruining" another, it's an entirely new industry that's being added. It's not like the spiders are going to get upset about us taking over their industry.

      On the topic of displaced workers though - there's always going to be a demand for "the real thing". While artificially produced diamonds may be exactly the same as naturally formed ones, for many people they are two entirely different things. It's all a question of perception. As long as people view the two things differently, there will always be a market for the rarer and consequently more expensive natural diamonds.
      • There can only be a market for "the real thing" if it's distinguishable from the "artificial" one. In the case of diamonds, the only distinction is that the artificial diamonds are too perfect. However, as someone already pointed out, it's quite likely that impurities can be added to the artificial diamonds in such a way that the two are indistinguishable. You can go to your corner jeweler, and he can swear that it's a natural diamond, but if there's absolutely no way to tell for sure, how will you know?

          nope, doping the diamonds won't work. It's not the presence of impure minerals in the diamond or lack thereof that make them distinguishable. Your local jewler will NEVER be able to tell the difference looking at this throuh any sort of magnification from a natural flawless diamond.

          It's the actual structure of the diamond on a molecular level that is too perfect. DeBeers themselves with their absolute mod sophisticated equiptment SUSPECT they will be able to identify them... but there is nothing in existing grading labs that can, and your local jeweler certainly cannot.

          But this mute and actually supports what your saying. The diamond market has been artificially kept afloat to this point. Contrary to popular belief diamonds are NOT rare, and I mean the natural ones. DeBeers simply controls the market by making sure all diamonds funnel through them and releasing them very slowly.

          In short this is an industry that exists in it's present form with inflated prices only because of a fraud. It's about damn time someone shut them down. Real jewelers have plenty of other items of jewelry they can sell, and there is nothing to stop them from selling diamonds, just not for thousands of dollars. Your corner jeweler won't go out of business because of this, but debeers will and it's about time they do.

        I have to agree.

        There is already a material being produced which is superior to spiders' silk in every way -- stronger, lighter, higher elongation-to-break, and easier to mass produce. It is called ultra-high molecular weight high-density polyethylene. Spectra is one form of the stuff; Dyneema is a superior form.

        UM-HDPE is basically the same stuff that garbage bags are made of ("ordinary" HDPE), but the polyethylene chains in it are several tens of thousands of times longer. This was made possible by the discovery of a new process by which to build the PE chains, using a new catalyst (and lots and lots of MAO, which always cracks me up).

        UM-HDPE production has been ramping up slowly over the past several years. In time, we should expect it to be fairly commonplace and inexpensive (Dyneema is currently extremely pricey stuff, due to limited production). So cracking the silk "code" is nothing to get riled up about, at least not from a material engineer's perspective. It's a johnny-come-latey. I seriously doubt its production could be ramped up any faster than Dyneema's, and Dyneema has a huge head start.

          I am really disturbed by the tendency of people to proclaim "scientists are no match for millions of years of evolution" after scientists understand (somewhat) another mystery. Look, this achievement is the first step after a long preparatory work. Now for the first time scientists really understand what is going on. Yes, they still don't know some aspects of the process, but they are just getting started. The area of bionics is booming. Just recently we could read in the news that engineers are building submarines that swim without propellers - by moving the "tail" instead. Yes, their crude attempts are no match for a dolphin, but give them time. We have supersonic aicrafts, we have spaceships, we can dig more than 10km deep into the Earth, we can move from the ocean surface into the Mariana trench in the same craft, we can build moving objects weighting million tons! Can the nature do that? Did the evolution do that? The answer is a resounding no!

          So wait a few years (at most a decade) and artificial spider silk will be stronger than natural. After a decade more we will have not only stronger, but ligher, more flexible, cheaper and overall better threads than any spider will ever have. Evolution is too slow and we gave it a huge start - billions of years. And we are gaining on it now.

      Searching ScAm's Ask the Expert [sciam.com] section, I found the following:

      "Dragline silk [a kind of silk all spiders make] is a composite material comprised of two different proteins, each containing three types of regions with distinct properties. One of these forms an amorphous (noncrystalline) matrix that is stretchable, giving the silk elasticity. When an insect strikes the web, the stretching of the matrix enables the web to absorb the kinetic energy of the insects flight. Embedded in the amorphous portions of both proteins are two kinds of crystalline regions that toughen the silk. Although both kinds of crystalline regions are tightly pleated and resist stretching, one of them is rigid. It is thought that the pleats of the less rigid crystalline regions not only fit into the pleats in the rigid crystals but that they also interact with the amorphous areas in the proteins, thus anchoring the rigid crystals to the matrix. The resulting composite is strong, tough, and yet elastic."

          Good question, but as there are lots of elastic yet non-sticky things out there, I would think that it should be possible to make non-sticky clothing out of this stuff.

          Maybe the spiders can decide whether or not to add an extra "stickiness" protein to the silk as they extrude it, so they can make non-sticky support strands for their webs. That way they could walk around without getting themselves stuck---or maybe they have some weird foot-based non-stick thing.

          Also, is silk from silkworms sticky?

To this day, Australian aborigines use the silk of a giant spider for fishing lines."

They have a small group of collectors - instead of raising the spiders, they buy mature females as needed.

          I have an old microscope repair manual that explained how one gets the silk from the spider ... if I recall you put the spider in a rather large container, with a tiny shelter at the top. They will run a long strand from the shelter down to the bottom of the container and make their messy trap web there, of sticky strands. You harvest the long strand on a loop of wire and then lay the strand onto the glass reticule, usin gan alignment jig. It's sticky enough to cling to the glass.

      Nope, sorry. If we used steel for a space elevator the cable would have to be as wide as the milky way. If we used something like kevlar or silk the cable would have to be as wide as the earth (better than steel but still not fesible). If we used carbon nanotubes the cable will only have to be 6 inches wide at the top.

      Until quite recently, spider silk had the highest tensile strength of any substance known to man, and the name Silksteel pays homage to the arachnid for good reason.

      Unfortunately, Silksteel Alloys are not sufficient to construct the space elevator. That calls for Super-Tensile Solids, which is quite a lot more advanced...

    SiLK which is used for microprocessor applications is not connected in any way to spider silk. The former is an acronymn for a resin
    (aromatic hydrocarbon) made by Dow Chemicals and used by IBM and other chip companies as an insulator between the multiple layers of wires on a chip. Silicon Low-K = SiLK

    "It's obvious that they couldn't have discovered the secret to making silk that quickly without access to SCO's intellectual property," said Darl McBride, SCO's president. He continued, "In 1999, they were making some silk, but it was low quality. Then, suddenly, over the course of a year or so, their silk became enterprise quality. Stuff that took other people 30 years took them months."

    In a move considered to be brilliant in the business world, SCO bought the patents on silk production from God in 2000 for an undisclosed sum. "We've been looking to leverage those patents ever since" said McBride.

    Right now, SCO isn't planning on suing individual spiders, although they won't rule out the possibility. "We've considering going after some of the nuisance species, such as brown recluses and black widows, first," said Chris Sontag. "We've been warned by our attorneys that doing such would expose us to the possibilities of bites and nasty wounds, so it's really something we don't want to do right now."

    Eric Raymond, president of the Open Silk Initiative, says that God lost protection on His silk production techniques by creating so many different species that use the intellectual property and not entering into any official licensing agreement with them. "It's a little late to be worrying about that now", said Raymond. A 1993 lawsuit regarding silk production methods also cast doubt on the validity of the patents.

    Meanwhile, some spiders have openly questioned Raymonds repeated assertions that he represents them or their opinions in these matters.

    A Quebec company, Nexia, has genetically engineered goats to produce spider silk within their milk. (Apparently, the way mammary glands work and the way a spider's silk glands work are remarkably similar.) I know that they've been able to pass the genes on to offspring, and they are getting silk from the milk now. I think it is supposed to be as strong as dragline silk, which is the strongest type of spider silk.


    I understand from the article that they've figured out how strong silk is actually produced, which should give them a heads-up on making a mechanical/chemical process to do all this artificially. It should be pointed out, though, that there are already means for production of non-artificial spider silk currently, which the article seems to have missed.

    Poor spiders. When in close confines, do you diagnose then with Arachnapobia or Autophobia [geocities.com] (fear of yourself)?

  • These poor defenseless spiders are being abused by the evil corporate silk manufactures, they are being held against their will to produce more of a substance than nature dictates they should...

    Redfield Gunsight used to have a whole area in their factory of black-widown spiders. They farmed them and valued them very much. If a spider was missing, they would issue an alert to locate the spider and return it to its home.

    The web from the black-widow spider was used to make the cross-hairs in their scopes. During the prime of their business, Redfield scopes were some of the very best ever made. All thanks to the silk from the black-widow spider farm.
