If you look at birds, which live a long time, cells from the birds tend to be more resistant to a lot of different environmental stresses like high temperature or hydrogen peroxide, things like that.

Or if they were dark cells, it was like iron corrugated, and he would put his fingers through.

For example, at the University of Minnesota, there's a biomedical engineer named David Odde, and he works with dancers to study how cells move.

So that allows cells to ooze along in the right directions.

But what seems so slow and graceful from the outside is really more like chaos inside, because cells control their shape with a skeleton of rigid protein fibers, and those fibers are constantly falling apart.

And you see the temperature rises to like 55 to 60 degrees C. If you do it for more than a second, it's enough to basically destroy the proteins of the cells.

What we're trying to do, or what the next step would be, is to make biocompatible polymers and maybe to write some things inside your body or inside the body of a worm, or to attach cells to our structures, and so on.

So when you look at something, like this image of this baby's face, it goes into your eye and it lands on your retina, on the front-end cells here, the photoreceptors.

What happens is is that, the front-end cells die, the photoreceptors die, and over time, all the cells and the circuits that are connected to them, they die too.

Until the only things that you have left are these cells here, the output cells, the ones that send the signals to the brain, but because of all that degeneration they aren't sending any signals anymore.

So, a solution to the problem, then, would be to build a device that could mimic the actions of that front-end circuitry and send signals to the retina's output cells, and they can go back to doing their normal job of sending signals to the brain.

And then the transducer then makes the output cells send the code on up to the brain, and the result is a retinal prosthetic that can produce normal retinal output.

Now just to orient you, each box is showing the firing patterns of several cells, and just as in the previous slides, each row is a different cell, and I just made the pulses a little bit smaller and thinner so I could show you a long stretch of data.

And so with the standard method, the cells do fire, they just don't fire in the normal firing patterns because they don't have the right code.

But there was this limiting factor, the issue of the code, and how to make the cells respond better, produce normal responses, and so this was our contribution.

So just the same way that we were able to jump over the damaged circuitry in the retina to get to the retina's output cells, we can jump over the damaged circuitry in the cochlea to get the auditory nerve, or jump over damaged areas in the cortex, in the motor cortex, to bridge the gap produced by a stroke.

A carcinogen is any substance or agent that causes abnormal growth of cells, which can also cause them to metastasize or spread.

Chemotherapy, one of the most effective ways used to treat cancer today, involves giving patients really high doses of chemicals to try and kill off cancer cells.

So we wanted to figure out how these ovarian cancer cells are becoming resistant to this drug called Cisplatin.

And in fact, it might be changing the cells themselves to make the cells resistant.

But they physically run in opposite directions, which creates a number of complications for your living cells, as you're about to see, most particularly when DNA is being copied.

But in each one of your cells, each strand of DNA is about 30 to 40 million nanometers long.

And again, you have billions of cells undergoing this process right now inside of you.

How do I explain to people that drug users deserve care and support and the freedom to live their lives when all we see are images of guns and handcuffs and jail cells?

Using this process, pioneers in the industry are layering up cells today.

In cancer, cells rapidly divide and lead to uncontrolled tumor growth.

These chains then progress and attach to the genetic material and pull the genetic material from one cell into two cells.

And this is exactly how one cancer cell becomes two cancer cells, two cancer cells become four cancer cells, and we have ultimately uncontrolled tumor growth.

And it prevents them from forming those chains, those mitotic spindles, that are necessary to pull the genetic material into the daughter cells.

What we see is that the cells will attempt to divide for several hours.
