Submission + - This is a true story; pics from a found camera

Anonymous Coward writes: "This is a true story; a friend of mine found a camera at an airport and forwarded me the following email. "Let's see if this email reaches the owner of the digital camera found at international airport in Salzburg (Austria). Forward it please and if it reaches the owner I would like to say: "You will never see your camera again: But your girl friend is very nice!" So I thought I better do my part and try and find the owner, lol. http://edrinker.com/2007/01/25/lost-and-found/"

Submission + - Ultra Dense Optical Storage -- On One Photon

brian0918 writes: "Researchers at the University of Rochester have developed a way to encode an entire image's worth of data into a single photon, store it, and retrieve the image intact. From the article: 'To produce the UR image, Howell simply shone a beam of light through a stencil with the U and R etched out. He turned down the light so much that a single photon was all that passed through the stencil. Quantum mechanics dictates some strange things at that scale, so that bit of light could be thought of as both a particle and a wave. As a wave, it passed through all parts of the stencil at once, carrying the 'shadow' of the UR with it. The pulse of light then entered a four-inch cell of cesium gas at a warm 100 degrees Celsius, where it was slowed and compressed, allowing many pulses to fit inside the small tube at the same time."
