Rock Band Weekly: V-Day Pack featuring Meatloaf, Stevie Nicks, more
Hey there, lonelyheart. Need some musical accompaniment for a Valentine's Day spent in romantic anguish? This week's Rock Band 3 update has your back -- not only is it eschewing the game's usual DLC schedule, dropping the tracks this Friday so that they'll be available on Valentine's Day, but each of the songs is an absolute heartbreaker. Though, ironically, most of them feature duets, which is kind of a slap in the face to lonely-folk like yourself. Check out the tracks from Meatloaf, Bonnie Tyler, Stevie Nicks and more after the jump!
Sonic 'laser' developed, makes quite an impression at 80s night
A researcher from the University of Nottingham and his Ukrainian colleague have built the world's first Saser: a device that generates a highly concentrated beam of sound waves at terahertz frequency. Not unlike the frenetic warblings of Welsh chanteuse Bonnie Tyler, when alternating layers of aluminum arsenide and gallium arsenide are exposed to an intense beam of light, photons are released, causing them to bounce back and forth between the layers. Eventually the sound waves combine into much stronger, highly concentrated sounds in which every particle is synchronized -- creating an ultra-high frequency "phonon" beam. Although practical applications for this technology have yet to be developed, it is hoped that Sasers could someday be used to probe and manipulate electronic devices at the nanoscale level, with results that include terahertz-frequency processors which would make the "computers of the future" a thousand times faster.
