| Researchers develop cell spray to repair hearts, healthy dose of electricity included Aug 4th 2012, 02:53  Spray-on solutions have found a place in green technology and even in transmitting radio waves, and they're no strangers to medical research, either. Researchers at the British Heart Foundation are working on a bioelectric spray composed of heart cells to help mend that most vital of organs. Because the cells need to be extremely thin to form a sheet of heart tissue, they are passed through a conductive needle that charges them with up to 30,000 volts. Exposing the cells to an electric field turns the solution into small droplets, which in turn form the cardiac sheet. The scientists can also add other types of cells to create "three-dimensional" tissue, which can be grafted onto injured hearts or sprayed onto scar tissue to help patients' tickers pump more strongly. As is so often the case, the next step will be testing the technology on animals, and the project's ultimate goal is to use this spray-on solution rather than making patients wait for donor hearts.

For $30 on a 3-year contract, or $400 contract-free, the carrier is offering an arguably improved version of the late 2011 RAZR (Droid RAZR for Yankees). Although it bulks up slightly to a third of an inch thick, it's still a skinny, Kevlar-clad wedge. The primary upgrade outside of the OS is a swap-out of that frankly mediocre Super AMOLED screen of the original RAZR smartphone for a much nicer ColorBoost LCD -- sorry, ColourBoost. Otherwise, you're getting the familiar 1.2GHz processor, 14.4Mbps HSPA+ data and 8-megapixel rear camera, although Motorola has shaved the built-in storage to 4GB to keep the costs down. We'd still be tempted to snag the Galaxy Nexus across the aisle to get us a taste of Jelly Bean for the same money, but Canucks with a penchant for Smart Actions now have an option outside of Rogers to get their fix.
