Genetically Modifying Silk Worms For Super Silk

New submitter davidshenba sends this quote from the BBC: "U.S. researchers have created silkworms that are genetically modified to spin much stronger silk (abstract). In weight-for-weight terms, spider silk is stronger than steel. ... Researchers have been trying to reproduce such silk for decades. But it is unfeasible to 'farm' spiders for the commercial production of their silk because the arachnids don't produce enough of it — coupled with their proclivity for eating each other. Silk worms, however, are easy to farm and produce vast amounts of silk — but the material is fragile. Researchers have tried for years to get the best of both worlds — super-strong silk in industrial quantities — by transplanting genes from spiders into worms. But the resulting genetically modified worms have not produced enough spider silk until now. GM worms produced by a team led by Professor Don Jarvis of Wyoming University seem to be producing a composite of worm and spider silk in large amounts — which the researchers say is just as tough as spider silk."

    1. Genetically modified spider escapes into the wild. It mates with other sipders creating a legion of these spiders with super silk. The super silk not only catches normal critters but large animals as well get tangled in the web unable to get out. Hope you all have a Phial from the elves.

    2. New spider silk isn't as sticky as normal spider silk. Spiders die of starvation. Pests grow to plague proportions

    3. Spider spins web in someones doorway. Homeowner is pissed at new wall.

    4. Profit! (GM spider escapes into the wild and mates with spiders in someones backyard. Patent troll finds GM spider and sues homeowner of ip theft and distribution!)

    it is unfeasible to 'farm' spiders for the commercial production of their silk because the arachnids don't produce enough of it

    These spiders obviously need a harsh lesson about the economic climate we live in. They're never going to produce enough if you just get some other creatures to make it instead. Rank all the spiders by silk production, fire the ones at the bottom of the list. Things'll soon turn around.

    coupled with their proclivity for eating each other

    That's actually a good sign. A little healthy competitive pressure.

  8. No spider farms? Great. by Vyse+of+Arcadia · · Score: 3, Funny

    I am extremely ok with spider farming being infeasible. Accidentally wandering into a spider farm is the stuff of nightmares.

    It amused me to see street sellers in NYC advertising pashmina shawls as '50% silk!' as if that was a good thing.

    Amazing, since otherwise they seem like the kind of people you can trust.
