The virus-based electrode produced a small current enough to flash "1" on a liquid-crystal display. A team of US researchers in California have used viruses to build tiny devices that gather energy from mechanical forces and convert it into electricity. “More research is needed, but our work is a promising first step toward the development of personal power generators, actuators for... 

Electrodes distributed over the brain of a volunteer A new study conducted in the University of California has enabled scientists to find a way to decipher actual words from human brain waves. A team of neuroscientists worked with a group of epileptic patients who were under the treatment for difficult curable seizures. They placed electrodes in a part of brain which is involved in understanding speech. They...
