I thought I would talk a little bit about how nature makes materials.

I brought along with me an abalone shell.

This abalone shell is a biocomposite material

that's 98 percent by mass calcium carbonate

And a lot of people might use structures like abalone shells,

I've been fascinated by how nature makes materials,

and they use proteins that are coded by the genetic level

that allow them to build these really exquisite structures.

What if they had some of the same capabilities

and adding no toxic materials back into the environment?

So that's the vision that I've been thinking about.

And so what if you could grow a battery in a petri dish?

Or, what if you could give genetic information to a battery

and do so in an environmentally friendly way?

And so, going back to this abalone shell,

is when a male and a female abalone get together,

that says, "This is how to build an exquisite material.

Here's how to do it at room temperature and pressure,

Same with diatoms, which are shone right here, which are glasseous structures.

they give the genetic information that says,

And you can do it the same, over and over again."

I like to say my favorite biomaterial is my four year-old.

But anyone who's ever had, or knows, small children

knows they're incredibly complex organisms.

to do something they don't want to do, it's very difficult.

So when we think about future technologies,

we actually think of using bacteria and virus,

Can you convince them to work with a new tool box,

Also, we think about future technologies.

And very rapidly, they became multi-cellular,

they could replicate, they could use photosynthesis

But it wasn't until about 500 million years ago --

during the Cambrian geologic time period --

that organisms in the ocean started making hard materials.

Before that they were all soft, fluffy structures.

that there was increased calcium and iron

And organisms learned how to make hard materials.

And so that's what I would like be able to do --

to work with the rest of the periodic table.

there's many structures like DNA and antibodies

and proteins and ribosomes that you've heard about

really exquisite structures on the nanoscale.

So here are some examples: these are some natural shells.

The abalone shell here -- and if you fracture it,

you can look at the fact that it's nano-structured.

that make small, single-domain magnets used for navigation.

is these materials are structured at the nanoscale,
