Artificial vision could be closer to reality, after scientists develop a tiny electric eye designed for use by microbots, which could ultimately help blind people too. Georgia State University researchers created the device using a new vertical stacking system, allowing it to be scaled down, and operate at micro-levels. The goal of the team, led by assistant physic professor Sidong Lei, is to create a micro-scale camera that could operate as the eyes of tiny robots, able to access areas humans, and larger scale bots can't reach. In the future, the team say the same technology could be adapted to bring vision to the blind, or improve color perception in the colorblind. The device makes use of synthetic methods to mimic the biochemical processes that allow humans to see, a step towards a micro-scale robot camera.

This week's milestones in the history of technology include the birth of Apple Computer, the first release of Gmail, and IBM signing an agreement with Harvard to build one of the earliest computers, the Automatic Sequence Controlled Calculator (ASCC), later called Mark I. Guglielmo Marconi receives the first wireless signal transmitted across the English Channel, sent from Wimereux, France, to his ship-to-shore station at the South Foreland Lighthouse outside Dover, England. The signal was a test held at the request of the French Government which was considering licensing the invention in France. Bell Telephone Laboratories announces the invention of the phototransistor, a transistor operated by light rather than electric current, invented by John Northrup Shive. An entirely new type of "electric eye" much smaller and sturdier than present photo-electric cells and possibly cheaper-has been invented at the Laboratories. During the past quarter century, electric eyes have found widespread use in electronics because of their ability to control electric currents by the action of light.
