To artificially produce spider silk with the help of genetically modified microbes and weave it as synthetic fiber, is our idea.

And this is what we see.

These are spinneret glands on the abdomen of a spider.

So those are my centromeres.

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

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

Let me erase all of that.

Let me draw that there.

And, of course, they're being aligned.

Spider silks also have a lot of potential for their anti ballistic capabilities.

So now we not only have a high fiber bread, but now fiber on top of fiber.

Textile News has a large following among those working in the textile industry.

Now, this is happening in two cells, of course.

And so we marvel at silk worms the silk worm you see here spinning its fiber.

Do you mind if I pull out one of your fibers?

Climb again over the course of 24 hours.

Those are centromeres.

And I decided to build it up.

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

The 350pound test monofilament.

And I looked at it beneath the microscope. And some of it was flat.

There's Kevlar in that chair.

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

Dietary fibre is good for losing weight.

Spin me a thread.

No fibers, flakes, hairs?

They produce six different types of silk, which is spun together into a fiber, tougher than any fiber humans have ever made.

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.

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.

You need to eat more fiber.

(Laughter)

You saw the spray going in.

We're starting to see these happening all around the world.

It's called memory cloth. Notice anything?

And Charlton Heston is made of a floating fiber, which I took out of the air.

We are developing spider silk.

Uh, no, actually. Ssa halko's retiring.

And some of them, as we learned, this is exactly what happened in mitosis.

In fact, this flagelliform fiber can actually stretch over twice its original length.

We're going to take some of that, and put it into the bread.

Cellulose is a type of carbohydrate found in plants that our body cannot break down.

But today, ultralight, ultrastrong materials,

Specifically, if you look on the vertical axis, that's stress.

The nearest we've come is with aramid fiber.
