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."

Just keep Peter Parker out of that lab

Then everything will be fine.

Re:Why is there any concern about GM 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!)
