gzipped_tar writes "According to Spiegel Online, 'A new computer game where players assume the roles of border guards and shoot people trying to escape from communist East Germany has unleashed a storm of controversy in Germany. The game's creator says he wanted to teach young people about history, but he has been accused of glorifying violence. ... The name of the multi-player FPS game, 1,378 (kilometers), was inspired by the length of the border between East and West Germany. ... [Players] choose between the roles of the border guards or would-be escapees: the escapee only has one goal — to get over the wall, but the border guard has more options, and can shoot or capture the escapee. He can also swap sides and try to clamber over the border defenses himself.' By choosing to play the border guard and kill the escapee, the player would win an in-game medal from the government of East Germany. But then the guard would time-travel forward to the year 2000, where he would have to stand trial. Jens Stober, 23, designed the game as a media art student at the University of Design, Media and Arts in Karlsruhe. He said that his intention was to teach young people about German history."

An anonymous reader writes "Peter Jansen, a PhD student and member of the RepRap community, has constructed a working prototype of an inexpensive table-top laser cutter built out of old CD/DVD drives as an offshoot of his efforts to design an under $200 open-source Selective Laser Sintering (SLS) 3D printer. Where traditional laser cutters use powerful, fixed-focus beams, this new technique dynamically adjusts the focal point of the laser using a reciprocating motion similar to a reciprocating saw, allowing a far less powerful and inexpensive laser diode to be used. The technique is currently limited to cutting black materials to a depth of only a few millimeters, but should still be useful and enabling for Makers and other crafters. The end-goal is to create a hybrid inexpensive 3D printer that can be easily reconfigured for 2D laser cutting, providing powerful making tools to the desktop."

fergus07 writes "Although much of the focus of pollution from automobiles centers on carbon emissions, there are other airborne nasties spewing from the tailpipes of fossil fuel-powered vehicles. These include nitrogen oxides (NOx). In the form of nitrogen dioxide it reacts with chemicals produced by sunlight to form nitric acid – a major constituent of acid rain – and also reacts with sunlight, leading to the formation of ozone and smog. Everyone is exposed to small amounts of nitrogen oxides in ambient air, but exposure to higher amounts, in areas of heavy traffic for example, can damage respiratory airways. Testing has shown that surfacing roads with air purifying concrete could make a big contribution to local air purity by reducing the concentration of nitrogen oxides by 25 to 45 percent."

Cryolithic writes "The largest cache of dinosaur bones ever found has been unearthed in Alberta. From the article: '... officials at the Royal Tyrrell Museum say the Hilda site provides the first solid evidence that some horned dinosaur herds were much larger than previously thought, with numbers comfortably in the high hundreds to low thousands. ... Rather than picturing the animals as drowning while crossing a river, a classic scenario that has been used to explain bonebed occurrences at many sites in Alberta, the research team interpreted the vast coastal landscape as being submerged during tropical storms or hurricanes. With no high ground to escape to, most of the members of the herd drowned in the rising coastal waters. Carcasses were deposited in clumps across kilometers of ancient landscape as floodwaters receded.'"

lilbridge writes "For over 1,500 years the Chinese have been using sticky rice as an ingredient in mortar, which has resulted in super strong buildings, many of which are still standing after hundreds of years. Scientists have been studying the sticky rice and lime mortar to unlock the secrets of its strength, and have just determined the secret ingredient that makes the mortar more stable and stronger. The scientists have also concluded that this mixture is the most appropriate for restoration of ancient and historic buildings, which means it is probably also appropriate for new construction as well."

lucidkoan writes "MIT researchers recently unveiled the world's first thin-film solar cell printed on a sheet of paper. The panel was created using a process similar to that of an inkjet printer, producing semiconductor-coated paper imbued with carbon-based dyes that give the cells an efficiency of 1.5 to 2 percent. That's not incredibly efficient, but the convenience factor makes up for it. And in the future, researchers hope that the same process used in the paper solar cells could be used to print cells on metal foil or even plastic. If they're able to gear efficiencies up to scale, the development could revolutionize the production and installation of solar panels."

theodp writes "Despite the whiff of danger, or perhaps because of it, the WSJ reports that the City Museum is one of St. Louis's most popular attractions. Housed in a 10-story brick building, the City Museum shows none of the restraint or quiet typical of most museums. It boasts a five-story jungle gym with two real-life jets kids can climb on, an enclosed Monster Slide that drops riders the length of three staircases, and a rooftop Ferris wheel. Sure, there are the occasional severed fingers and skull fractures, but museum founder Bob Cassilly contends that it is as safe as it can be without being a bore. 'They [lawyers] are taking the fun out of life,' says Cassilly, adding that 'when you have millions of people do something, something's going to happen no matter what you do.'"

separsons writes "Researchers at Japan's Tohoku University designed a new shape memory metal alloy. The super elastic iron alloy can endure serious stretching and still return to its original shape. The scientists say that once optimized, the material could be used in everything from braces to medical stents to earthquake-proof buildings!"

krou writes "After food activist and author Raj Patel appeared on The Colbert Report to promote his latest book, things seemed to be going well, until he began to get inundated with emails asking if he was 'the world teacher.' In events ripped straight from The Life of Brian, it would seem that Raj Patel's life story ticks all the boxes necessary to fulfill prophecies made by Benjamin Creme, founder of religious sect Share International. After the volume of emails and inquiries got worse, Patel eventually wrote a message on his website stating categorically that he was not the Messiah. Sure enough, 'his denial merely fanned the flames for some believers. In a twist ripped straight from the script of the comedy classic, they said that this disavowal, too, had been prophesied.'"

bleedingpegasus sends word that the US Air Force will be grabbing up 2,200 new PlayStation 3 consoles for research into supercomputing. They already have a cluster made from 336 of the old-style (non-Slim) consoles, which they've used for a variety of purposes, including "processing multiple radar images into higher resolution composite images (known as synthetic aperture radar image formation), high-def video processing, and 'neuromorphic computing.'" According to the Justification Review Document (DOC), "Once the hardware configuration is implemented, software code will be developed in-house for cluster implementation utilizing a Linux-based operating software."
