Everybody knows that your various appliances have wattage, right?

So really what I'm doing is using these fantastic little devices.

The problem is that current prosthetics don't work very well. They're still very limited in the vision that they can provide.

Virtually none. All of our equipment, including film equipment, was charged by the sun.

I was very lucky to come to the US right after high school, and was able to work on this technology and develop some devices.

Since the rise of reconfigurable programmable logic devices, sharing of logic designs has been a form of open source hardware.

And my immunologist told me that I should also wipe down all of the remote controls and iPhones in my house, because those are just orgies of germs.

There are some drug treatments, but they're only effective on a small fraction of the population. And so, for the vast majority of patients, their best hope for regaining sight is through prosthetic devices.

But why is the technical overload crisis, the complexity crisis, accelerating now? In the hardware world, it's because we the consumers want everything to be smaller, smaller, smaller.

Comparable geared devices did not emerge in Europe until the 16th century, and it was not until 1645 that the first mechanical calculator capable of performing the four basic arithmetical operations was developed.

So there's a language of light in the deep ocean, and we're just beginning to understand it, and one way we're going about that is we're imitating a lot of these displays.

And so, you know, for example, with these devices, patients can see simple things like bright lights and high contrast edges, not very much more, so nothing close to normal vision has been possible.

So I'm really a basic scientist, not a clinician, but in the last year and a half I've started to switch over, to use what we've been learning about these patterns of activity to develop prosthetic devices, and what I wanted to do today is show you an example of this.

At TED Cannes, Gary Wolf gives a 5 min intro to an intriguing new pastime using mobile apps and always on gadgets to track and analyze your body, mood, diet, spending just about everything in daily life you can measure in gloriously geeky detail.

The security forces were on full alert and were throwing everyone out of the explosion scene so that nobody gets any information or take any pictures (my camera was about to be confiscated). Excuse me if I wasn't able to take pictures because of the state of horror among people and the security forces beating up people to disperse them from the scene.

The vasopressin analogue ornipressin was found in a number of studies to be useful in improvement of kidney function in patients with hepatorenal syndrome, but has been limited in its use, as it can cause severe ischemia to major organs.
