Scientists Crack Silk's Secret

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."

Whenever they wander into other webs, it is the male that does the wandering as only the male searches for a female mate. Your picture, the male most-likely found himself one hell of a female, although much bigger, he most-likly mated with her and wasn't successful in its retreat. Some male spiders, after finding a mate, will actualy stay around the female and eat the same food she eats, allthewhile at risk of being eaten himself. They don't establish any kind of relationship, as most females simply can't see the male and neither can sense the male's intentions or even its movments on her web. You can say, the male spider is always staring at death by being around the female. Too bad the infamous and extice nerd spider stayed too far from females, as they would have inherited the earth as shown in the Holy Bible; or perhaps inheriting the earth has a twist on it as the "ashes to ashes, dust to dust" verse about the body returning to the earth.

To my understanding, many male spiders don't create such webs as does the females, at-least in many species the male simply is a moocher that travels to different areas to mooch from the females.

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.

"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."

Other benefits from silk over todays Kevlar vests include lighter weight, increased mobility, and better side protection.

      While you are correct about products such as Spectra and Dyneema being more readily available, it remains to be seen how quickly this silk can be mass manufactured.

      As for Law Enforcement USE, Spectra is worthless. There is currently quite a stir being caused by spectra. It turns out that Second Chance(a body armor manufacturer) used it even though it wasn't rated by the manufacturer of Spectra for such uses). The Problem? The vests have failed several times, after relatively short periods from the time of their purchase(read: within 5-6 months.) The material doesn't hold up well if it gets over a certain temperature, and naturally, the human body, especially one which is physically active, emits more than enough heat to cause the spectra to fail.

Russia and China both had good reasons for going Communist - the feudal systems they were both locked in were certainly no paradise - and atheism held widespread appeal largely as a reaction to the barbaric excesses of the religious regimes they replaced.

    The reality is that the overthrow of many of the church-supported monarchies in Europe lead to the formation of dictatorships that were formally or informally opposed to religion (it happened to one degree or another in France and England, for example). No surprise there - in times of chaos, dictators frequently seize control (Hitler being a prime example), and in cases where the church was propping up a corrupt monarchy, it's no surprise the dictators who replaced it would do everything in their power to break the church.

    Organized religion has been on the decline in Europe now for decades. I certainly don't see them slipping into anarchy or totalitarianism. Unlike the far more religious United States, they still respect international law and elect their leaders . . .

    Of course, the Mongols make everybody look like amateurs. They slaughtered 40 million in the 13th century, putting them on par with Mao and WWII. That's pretty impressive, given that the global population at the time was under 500 million. China's population dropped from 115 million to 85 million between 1200 and 1300 as a result of their "efforts."

    I am a Christian and agree with some of what you have said.

    "Since there were far more people on the earth during "modern" history than there were in the past, this is hardly a relevant point."

    You are correct. This is not a relevant point. Comparing numbers as to who has done the most bad or killed the most people doesn't do any good. All groups have done their fair share of terrible actions and we should all recognize this.

    The thing I can say though, about those "Christians" or "professed Christians" that have done those terrible things is; they were not living up to God's standards as revealed to us in the scriptures. Even though their modivation may have been to spread God's kingdom or to live up to God's standards they were not doing these things God's way. Atheists, on the other hand, cannot make such a claim because they have no objective standard. They cannot say that those groups were not living up to best-embodied standard of atheism because atheism has no moral standards. Atheism is a "might makes right" standard of living. You may not agree with me but any other moral standard that an atheist tries to employ into his or her life will be foundationless because of the subjectivity of the religion. It will have meaning for the individual but cannot hold any lasting or universal meaning.

    "Replacing one f****d-up, reality-denying philosophy (say, Christianity as it's been practiced traditionally) with another (say, Communism) isn't likely to lead to an improvement in anybody's quality of life."

    I do not consider Christianity a "reality-denying philosophy". "How is Christianity a "reality-denying philosophy"? Who's reality does it deny? Yours? If you are an Atheist you believe that evolution is fact and the earth is billions of years old. If you are saying that Christianity denies that reality you would be correct.
    I believe that God created the earth in 6 days. This is reality based on my philosophical worldview and based on this your Atheism denies reality but to say this simply shows my bias. It does nothing to further a dialog or prove a point. I am not saying that reality is different for each person but everyone's sense or view of reality may be different. Ones personal views can alter thier view of reality. The true question is, does Christianity deny your personal sense of reality (Personal Beliefs) or reality itself? If it denies reality what examples can be given?

    Lastly I would like to ask how Atheism can "lead to an improvement in" someone's "quality of life"? I didn't ask how science could lead to an improvement. I asked how Atheism as a philosophical worldview could.

    I could continue to write on this subject but I just do not have any more time for it :)

    I hope this post was not viewed as an attack on Atheism or you as a person. I hold the view that Atheism is wrong in its views yet I hold no animosity toward those that hold that view and I apologize if this post came as such.

    Peace be with you
