"Scientists make super-strong metallic spider silk"
 
By Ben Hirschler Ben Hirschler 
April 23, 2009

"LONDON (Reuters) – Spider silk is already tougher and lighter than steel, and now scientists have made it three times stronger by adding small amounts of metal.

The technique may be useful for manufacturing super-tough textiles and high-tech medical materials, including artificial bones and tendons.

"It could make very strong thread for surgical operations," researcher Seung-Mo Lee of the Max Planck Institute of Microstructure Physics in Halle, Germany, said in a telephone interview.

Lee and colleagues, who published their findings in the journal Science, found that adding zinc, titanium or aluminum to a length of spider silk made it more resistant to breaking or deforming.

They used a process called atomic layer deposition, which not only coated spider dragline silks with metal but also caused some metal ions to penetrate the fibers and react with their protein structure.

Lee said he next wanted to try adding other materials, including artificial polymers like Teflon."

Status: offline 		This article is interesting, and cool.  I'm not a science geek, but have always been very interested in the subject.  Reading something like this makes Me wonder how people get the idea to try experiments like this.  I remember hearing a long time ago that spider silk is much stronger than steel.

Too bad it has to come from such a creepy-crawly critter.  I'm not an arachniphobe (exactly), but I really don't like the little buggers.  Squash them without remorse (and yes, with glee) whenever I find one in the house.  After I work up the nerve to get close enough to them to do it.

*glares up at one in the room right now, nested where the wall and ceiling meet, right above the doorway, and completely out of  reach....*     Any tall subby boys out there want to come over here and kill it for Me?  Or catch it, and send it off to a lab somewhere to be experimented on?

What a wicked web they'll weave, once they breed the genes they receive....

As an aside there are Native American stories about spider weaving the alphabet and the word "arachnid" comes from the Greek myth of Arachne.

Hmm. Sounds like you never had a pet spider. Maybe I should be a pal and fix that for you. Maybe something huge, that you could pet.

Thank you for the most generous offer but no doubt such an excellent specimen will be better understood and cared for by someone who appreciates it's unique contributions to the ecosystem, meaning you can keep the fuzzy arachnid.

Just trying to help you appreciate exquisite uniqueness of the spider. Whereas a regular guy like me would just squish it and keep going, I know a person of your sensitivity to nature would give it a good home. What was that? This one and one that jumps? Excellent.

I hate walking into a spider line outsideand then wondering "is it on my back?  did it hitch a ride on my jeans?"

They have a place...OUTSIDE.   I mean, I've held tarantulas in Belize.  All good....she went back to her nest.  But if she came in the house, I'm afraid she'd meet "Mr Shoe"

I hate getting spider webs on me. It always feels like you din't get it all off. And that stuff sticks like damn glue.

Thing is about spiders, they come out to play when you go to sleep, a seemingly spider free home becomes a zoo for insect life at the dead of night when it is all quiet. A good reason to have a cat, but a spoiled cat can't be bothered hunting insects.

I used to be real fearful of spiders when I was a bin lid, now, no problems, mind my attitude to spiders changed when I literally got chased by one of

these buggers

Not technically a spider, but it has a foot in both the spider and scorpion camps, oh and scorpions tend to come off worse when scrapping with these things.

Both good things at first glance and believe me I am not one who is against doing these things ordinarily, but I have to wonder what happens if the spiders escape... Chaos theory of Life.. Life will find a way.

Bondage scenes should not be instituted by spiders while you are asleep.
