He's dying. Coronary blockage.

Now, this pore can open and close.

This is an example of where a blockage occurs.

What happens after you have the heart attack, this blockage?

Here is an even more challenging example where our robot Junior approaches a complete road blockage, but its target location is behind the road blockage.

And these are individual potassium ions that are flowing through that pore.

A means to determine if there's a complete blockage of a coronary artery.

Because the light activated pore is encoded in DNA, we can achieve incredible precision.

And it sits in the membrane of the cell and it's got a pore in it.

So, what you have is that when the pore is open, you get some current sometimes.

This vehicle will eventually be able to drive in a different direction and reach the goal point behind the blockage.

You can see that the skin pore structure changes enormously from stretched skin pores to the regular skin texture.

You can exploit this to make sure that only some neurons contain our light activated pore and others don't.

Well, he kept the balloon filled to block the artery, to simulate a blockage, which is what a heart attack is.

Whenever a flash of light hits the receptor, the pore opens, an electrical current is switched on, and the neuron fires electrical impulses.

So if you think about the pore size in the agarose, it has pretty big pores, so imagine it looking kind of like this.

So in this cartoon, the bluish white cell in the upper left corner does not respond to light because it lacks the light activated pore.

We're pulling out, we're zooming out, out through a nuclear pore, which is the gateway to this compartment that holds all the DNA, called the nucleus.

Susana had engineered the fruit fly on the left so that just two out of the 200,000 cells in its brain expressed the light activated pore.

So you can see it do its job until it finally breaks free and is able to navigate around this blockage onto a different street, as shown over here.

So for example, you might have 0, 2 over here, and 1 over here but what should be the case is when there is a full blockage the right side should just never expand.

And, as a result, it's a very good cue to the detailed shape of the skin pore structure and all of the fine wrinkles that all of us have, the things that actually make us look like real humans.

And recall when your Lord inspired the angels 'I am certainly with you. So make firm the feet of those who believe. I will cast terror into the hearts of those who disbelieve. So strike at their necks and strike at every pore and tip.

And even when you close the pore which neurons can do, they can open and close these pores to generate electrical activity even when it's closed, because these ions are so small, they can actually sneak through, a few can sneak through at a time.

We can inject these dyes into the bloodstream, so that when we do a new vessel and we bypass a blockage on the heart, we can see if we actually made the connection, before we close that patient back up again something that we haven't been able to do without radiation before.

So, if we use information that comes off of this specular reflection, we can go from a traditional face scan that might have the gross contours of the face and the basic shape, and augment it with information that puts in all of that skin pore structure and fine wrinkles.

And when you have a blockage, the alarm goes off and it sends the alarm and the electrogram to an external device, which gets your baseline electrogram from 24 hours ago and the one that caused the alarm, so you can take it to the emergency room and show them, and say, take care of me right away.
