www.ted.com Cheryl Hayashi studies spider silk, one of nature's most high-performance materials. Each species of spider can make up to 7 very different kinds of silk. How do they do it? Hayashi explains at the DNA level -- then shows us how this super-strong, super-flexible material can inspire.

I freely admit, I am arachnophobic, but I found this to be incredibly fascinating. I had NO idea a single spider could produce multiple silks!

I think you're just "scared" of spiders. If you actually had the phobia would probably have a panic attack just hearing the word spider

It is always a pleasure to listen to someone speak who is passionate about what they do and take great effort in sharing their knowledge and joy with others. I love how she glazed over how spider silk can be useful to humans, she stands in awe of them.

I don't think spider silk is the easiest thing to come by, takes a lor of time and many of them to make stuff, see the golden orb weaver silk weaving project, guys took quite a while in make those things, and a lot of them.

I think that if a scientist figured out a way to replace the proteins in a chickens egg with that of the proteins of spider silk, we could more easily synthesize spider silk for industrial use purposes. Knowing how strong these materials are, and maybe even pairing with carbon nanotubules we could theoretically create a material capable of helping us engineer a space elevator.

@AngeloWillems "Due to the difficulties in extracting and processing substantial amounts of spider silk, there is currently only one known piece of cloth made of spider silk, an 11-by-4-foot (3.4 by 1.2 m) textile with a golden tint made in Madagascar in 2009. 82 people worked for four years to collect over one million golden orb spiders and extract silk from them." -wikipedia. So.... no. I seriously doubt that.

@ecvanbrussel i think that the 'toughness' refers to the strength of the individual fiber as compared to its own weight; as i dont see why we would use Kevlar for bullet proof vests and such if nylon were stronger. although honestly i dont know XD

It's not a question if one could eat spider silk or any other substance, but rather, what are the effects on the human body.
@tigress63
@tigress63 6 лет назад
I thought it was intuitive that scytodids would have a very tough drag line because its prey would be bigger and more or less the one chance to capture it's prey. With a web the smaller prey gets tangled. It's similar to how people fish- depends what you're fishing for... With a net you get smaller bodied prey opposed to single line 80lb line used for larger prey.

Scientist still can’t reverse engineer a spider’s silk in a lab. They say it’s not the same; the spider’s silk is one-of-kind.

"Until quite recently spider silk had the highest tensile strength known to man. And the name silksteel pays homage to the arachnid for good reason. -Commissioner Pravin Lal, 'U.N. Scientific Survey'" That's what came to mind when I saw this, though I'm aware it's scientifically inaccurate.

11:33 She doesn't seem to know Darwin's bark spider. It is an orb-weaver spider that produces silk with an average toughness of 350 MJ/m3. Some fibres have 520 MJ/m3. Imagine, where the dot for that would be. :)
