And we found, to our surprise, that we not only got bone marrow out, but we got 10 times the stem cell activity in the marrow from the Marrow Miner, compared to the normal device.

Expressive spaces are not spaces that simply confirm what we already know.

So actually how do we harvest this bone marrow?

Daniel Kraft demos his Marrow Miner a new device that quickly harvests life saving bone marrow with minimal pain to the donor. He emphasizes that the adult stem cells found in bone marrow can be used to treat many terminal conditions, from Parkinson's to heart disease.

We use those in my field of bone marrow transplantation.

Daniel Kraft invents a better way to harvest bone marrow

And the Marrow Miner, the way it works is shown here.

Expressive spaces may disturb us.

It shall be health to thy navel, and marrow to thy bones.

It shall be health to thy navel, and marrow to thy bones.

We can democratize our public spaces.

Planting productive trees throughout urban spaces.

More people, smaller spaces, less stuff.

If the empty spaces is less than the amount of spaces, the turtle needs to live, the turtle needs to die.

It provides a physical support structure for the trees, and it creates physical spaces, habitable spaces inside of the sand dunes.

His pails are full of milk. The marrow of his bones is moistened.

His pails are full of milk. The marrow of his bones is moistened.

His breasts are full of milk, and his bones are moistened with marrow.

His breasts are full of milk, and his bones are moistened with marrow.

These are the spaces that are not just luxurious spaces for some of us, but are important for everybody in this world.

We're producing spaces that accommodate human activity.

So there's no trouble accessing battle spaces.

There were 82,000 spaces in 1997, whereas, in 2005, there are 187,000 spaces at reduced rates in the network of early childhood centers.

We've just come out, we're commercializing, this year, generation 2.0 of the Marrow Miner.

We take our own bone marrow cells and treat a patient with a heart attack, we can see much improved heart function and actually better survival using our own bone marrow drive cells after a heart attack.

That should gives us number of empty spaces.

And, of course, expressive spaces are not mute.

It's spaces like these that spawned personal computing.

We need shared spaces for interaction and collaboration.

In many countries, the supply of blood for medical purposes relies on voluntary, anonymous donations. Worldwide, more than 11 million people have put their names on donor registries for bone marrow, signifying their willingness to donate their marrow to a stranger.

All I have to do is merge the spaces.

I like doing more than just exploring these spaces.

There were no parks there were no green spaces.

And perhaps these, in the end, as celebratory spaces.

We can do that in commercial spaces like this.

The eternal silence of these infinite spaces terrifies me.

The goal is to reach 200,000 spaces in 2006.

I invented a device called the MarrowMiner, a much less invasive way for harvesting bone marrow.

We're sending his marrow across the country to save the life of a child with leukemia.

So why should you care? Bone marrow is a very rich source of adult stem cells.

It may encourage more people to sign up to be potential live saving bone marrow donors.

And it has billions of interstitial spaces, and those spaces, along with the nanoparticles, reach up and grab the air molecules, and cover the surface with air.

And that's not always going to happen in physical spaces.

And all throughout the library are different objects, different spaces.

And so this informs, among other things, of course, a treatment for bone marrow transplant, which he undertakes.
