Nano-Optical Switches To Restore Sight? 51

Roland Piquepaille writes, "Researchers in California are now using light to control biological nanomolecules and proteins. They think it can help them to develop treatments for eye diseases, such as the loss of the light detectors in the retina that is a major cause of blindness. They envision putting some of their nano-photoswitches in the cells of the retina, restoring light sensitivity in people with degenerative blindness such as macular degeneration. It will be a while before this technique emerges from the laboratory. ZDNet has additional references and pictures of what you can do with these photoswitches."

Mapping Interior Spaces With Robots And GIS 47

Roland Piquepaille writes "In an article about GIS and Robotics, Directions Magazine reports that architects and other professionals can now use spatially intelligent robots to collect interior space data. With such mapping robots, it's possible to capture accurate data for over 10,000 square meters per day and to easily integrate it with existing software. The article doesn't mention the sources for its illustrations about these robotic systems, so I thought I'd point them out: a company in Maine called Penobscot Bay Media. You'll find more details and pictures about these mapping robots at ZDNet."
