Prototype projector is bright enough for lit room
Researchers at the Uchida Research Laboratory at Tohoku University have created a prototype projector that creates images that are clearly visible even in brightly-lit rooms. The projector uses Diffused Light Control (DLC) to attain this goal and thus only light from the projector is diffused towards the viewer. All other external light is either reflected away or absorbed.

Sony, university create tech for 1TB Blu-rays
Researchers at Sony together with those at Japan's Tohoku University said they have developed a blue-violet laser that can create 1TB Blu-ray discs. The ultrafast pulsed semiconductor laser has a laser wavelength of 405 nanometers and can generate optical pulses just the picoseconds in duration. Moreover, the new laser doesn't require a large light source and a specialist technician to operate, as required in the past with similar technology.
