Spray-on gadgetry isn't exactly new, but the possibility of spritzing a computer on your epidermis most certainly piqued our interest. A team of Scottish scientists have reportedly "developed a computer the size of a matchstick head, thousands of which can be sprayed onto patients to give a comprehensive analysis of their condition." The device(s) joins the ever-growing array of communication-enabled health sensors aimed at helping the elderly stay in contact with their doctors even in remote locations, and can compute a variety of inputs such as blood pressure, muscle movement, and pulse rate. The technology, dubbed speckled computing, can even be rigged to transmit information via radio waves, meaning that a full-fledged diagnostic report could get a whole lot less invasive if this stuff pans out.

Considering that ATI and NVIDIA don't seem to be making any substantial strides in reducing the amount of energy required to run their products, it's a tad surprising to hear of an entire supercomputer running a bit leaner than the competition. Hoping on the ever-growing green bandwagon, University of Edinburgh developers are at it again, this time crafting an uber-speedy machine that's reportedly "ten times more energy efficient and up to 300 times faster than its traditional equivalents." Based on field programmable gate arrays (FPGA), the chips are not only very difficult to program, but they can currently only be used "to perform very specific tasks." Of course, the creators are more interested in the extreme number crunching and power saving abilities than anything else, and while no commercial uses have been identified just yet, the machines could purportedly be used in fields such as "drug design, defense and seismology."
