Counting On Toes - SpaceDaily  Our four-legged, five-toed ancestors conquered the land earlier and more independently than expected, say paleontologists studying newfound 345 to 359-million-year-old tracks at an eroding beach in eastern Canada. At least six different kinds of four-limbed reptile-like animals - a.k.a. tetrapods - with five digits on their feet left their tromping prints in the mud of what was once a tropical swamp at Blue Beach, Nova Scotia. The five-digit tracks range in size from four inches to less than an inch and seem to contradict the prevailing idea that the first tetrapods had wide variety of other-than-five-toed (polydactyl) feet, out of which five-toed (pentadactyl) animals later won out as the most efficient on land. It's also the evolutionary step that set the stage for our ten fingers and toes.  
China Developing New MagLev Train - SpaceDaily  Left:  The sample Magnetic Array Suspension train debuts at the Sixth Shanghai International Industry Fair. The MAS train is powered by a combination of attraction and repulsion generated from permanent magnets both on the train and the tracks. A Shanghai physics professor says he has the technology for the first magnetic train fully developed in China. Wei Lehan, 66, a professor at Shanghai Normal University, says the Magnetic Array Suspension (MAS) system he developed is the first in the nation with independent intellectual property rights. Building an MAS system, he said, would cost about 30 million yuan (US$3.6 million) per kilometre, about one-10th what the German technology would cost. It would also save considerable amounts of land and energy. 

R2 Unit, Meet 912 Unit: The Hackable Home Robot - Space.com   The 912 unit is basically a robotics platform; it runs on a Windows operating system and can use off-the-shelf components. The 912 comes with a Windows-based application to control the robot. It is a GUI-based application that provides vision-based navigation, object recognition, speech recognition, speech synthesis and other features. The company shows several versions so you can see what is possible. The 912 "MP3" version features a DVD-ROM device with a 5.5 inch screen on the back of the robot for playing games or watching movies. You can tell the robot to play mp3's, or burn them to a disk to give to friends. The 912 "HMV" version shows its tough-guy side as a sentry-duty robot.
