'Artificial leaf' makes hydrogen from solar cell | Green Tech - CNET News
Massachusetts Institute of Technology professor Daniel Nocera thinks he can draw cheap and clean energy from water.
At the National Meeting of the American Chemical Society, Nocera yesterday presented results from research on making an "artificial leaf" to split water to get hydrogen fuel and oxygen. The goal is to use the solar cell to make hydrogen, which would be stored and then used in a fuel cell to make electricity.

Microrobot used to administer drugs in eyes

Microrobot used to administer drugs in eyes

Some scientists at the Institute of Robotics and Intelligent Systems in Switzerland are developing tiny, electromagnetically controlled microrobots that can swim on the surface of a patient’s eye. These robots then stay there for months, releasing drugs.
But knowing such a technology exists gives us hope that in the future we’ll have microrobots battling viruses in our bodies. What an epic battle that would be. Hit the break to watch a demonstration of the microrobot being tested on a dead pig’s eyeball: http://bcove.me/li84ci6u

The first retinal prosthesis has received European approval for clinical and commercial use. People blinded by degenerative eye disease will have the option of buying an implant that can restore their vision at least partially.

"It marks the beginning of an era in which sight will be restored at ever more astonishing levels," says Robert Greenberg, president and CEO of Second Sight, the California company that developed the device.
