Cheryl Hayashi The magnificence of spider silk

So silk comes out of the spinnerets, and for those of us spider silk biologists, this is what we call the business end of the spider.

To give you an idea of what a spider silk protein looks like, this is a dragline silk protein, it's just a portion of it, from the black widow spider.

This is a picture of the spinnerets coming out of a spider and the silk being formed from a spider. Isn't that beautiful?

It's short. And on the bottom, this is the repeat sequence for the egg case, or tubuliform silk protein, for the exact same spider. And you can see how dramatically different these silk proteins are so this is sort of the beauty of the diversification of the spider silk gene family.

These are the two species of spiders for which the vast majority of time and money on synthetic spider silk research has been to replicate their dragline silk proteins.

Instead, Wendt and her team turned to spider silk, which is known to be 5 times stronger than Kevlar.

This makes testing spider silk really, really easy to do in the laboratory, because we're actually, you know, testing it in air that's exactly the environment that spiders are using their silk proteins.

At some point, the force exerted by moving air upon the silk threads is great enough to launch the spider into the air.

Each of these silk fibers exits from the spigot, and if you were to trace the fiber back into the spider, what you would find is that each spigot connects to its own individual silk gland. A silk gland kind of looks like a sac with a lot of silk proteins stuck inside.

In an orb web weaving spider, you can find seven types of silk glands, and what I have depicted here in this picture, let's start at the one o'clock position, there's tubuliform silk glands, which are used to make the outer silk of an egg sac.

It's like the spiders are sharing an ancient secret with me, and that's why I'm going to spend the rest of my life studying spider silk.

So if you ever have the opportunity to dissect an orb web weaving spider, and I hope you do, what you would find is a bounty of beautiful, translucent silk glands.

Spider Three Decks

It's the combination of strength, extensibility and toughness that makes spider silk so special, and that has attracted the attention of biomimeticists, so people that turn to nature to try to find new solutions.

Here is a pest, devastating pest, a spider mite, because it does a lot of webbing like a spider.

The silk at this stage is known as raw silk.

In addition to these biomimetic applications of spider silks, personally, I find studying spider silks just fascinating in and of itself.

The parable of those who take guardians instead of Allah is that of the spider that takes a home , and indeed the frailest of homes is the home of a spider , had they known !

What silk biologists do is we try to relate these sequences, these amino acid sequences, to the mechanical properties of the silk fibers.

The belief of considering other things as one 's guardians besides God is as feeble as a spider 's web . The spider 's web is the frailest of all dwellings , if only they knew it .
