Thought-pad on the way......

It is possible to manipulate complex visual images on a computer screen using only the mind. The study, published in Nature, found that when subjects had their brains connected to a PC displaying two merged images, they could force the computer to display one of the images and discard the other. The signal transmitted from each subject's brain to the computer were derived from just a handful of brain cells. The study reflects progress in the development of brain-computer interfaces (BCIs), devices that allow people to control computers or other devices with their thoughts. BCIs hold promise for helping paralysed individuals to communicate or control prosthetic limbs.

Shiny Brazilian beetle may lead to futuristic Computers

Researchers have discovered that the structural arrangements seen on a shiny Brazilian beetle may lead to futuristic computers that use light rather than electricity to process information. Scientists have long dreamed of computer chips based on light rather than electricity. In " optical computing" chips would need photonic crystals to channel light particles. Potentially these beetle scales could serve as a mold or template to which semiconductor material, like titanium or silica, can be added. The original beetle material can then be removed with acid leaving an inverse structure of the beetle crystal, a now usable photonic crystal in the visible light regions.
