Qrio – short for quest for curiosity – is Sony's 58-centimetre-tall, all-dancing, bipedal humanoid robot. Qrio is famous for such feats as conducting the Tokyo Philharmonic Orchestra in a unique rendition of Beethoven's 5th symphony, navigating an assault course, and even roller-skating. See footage of four QRIOs performing a complicated dance routine, (Windows Media Player required) recorded in December 2003. Starting in 2002, MIT spin-off iRobot, of Massachusetts, US, finally brought domestic robots to the masses, with their small and affordable Roomba and Scooba vacuuming and mopping robots – retailing at less than $200. Sales of all household robots have boomed, and in 2005 more than a million were thought to be in operation worldwide.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display
