I got no strings to hold me do...

Is it prey? Is it predator? Is it mate?

To answer that, you have to look a lot closer at the spinneret region of a spider.

I got no strings to hold me down To make me fret or make me frown

It's short.

Which is best, white thread or red thread?

Which is better, red thread or white thread?

We do chemistry in organic solvents.

You can see multiple fibers coming out of the spinnerets, because each spinneret has many spigots on it.

Do you see that blind thread that missed the weave and lies on top of the others?

Let me erase all of that.

She sews with a needle and thread.

I got no strings, but I got the brain

It has four pairs of large eyes, curved legs, eight curved legs, and spinnerets.

And the most studied silk line of them all major ampullate silk.

For example, this garden spider can make seven different kinds of silks.

We'll do a whole series of videos on the actual mechanics of that, but it splits by a mechanism called mitosis.

If the vertical thread is on top It's a one.

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.

So those are my centromeres.

Coloured cotton.

Just like Moses called it.

The silkworm is spinning a thread.

I do wish you'd shed Some light on this mystery.

I have a needle and thread.

When you look at this orb web, you're actually seeing many types of silk fibers.

Oh, that's the storeroom for canvas and Dacron and And line.

And then you can guess what happens in anaphase Il.

So what I want to do is say to a future bug,

You did it. You did it.

My grandma stooped down and picked up a needle and thread.

My grandma bent over to pick up a needle and thread.

One of us wouldn't have even made it into flight school if his old man, his daddy, hadn't pulled the strings!

If we all just go our own way, our nation will be stronger for it.

It's in its chromatin form.

See me for a bit.

This thread tangles easily.

Nye So what's this right here?

I first proposed, in the early 1990s, that mycelium is Earth's natural Internet.

A long thread is easily entangled.

A long piece of thread easily becomes tangled up.

And the whole thing is sort of symmetrical.

If you look at the maximum stress value for each of these fibers, you can see that there's a lot of variation, and in fact dragline, or major ampullate silk, is the strongest of these fibers.

I think it's important.
