LilaG writes "Drug tests spot banned substances based on their chemical structures, but a new breed of narcotics is designed to evade such tests. These synthetic marijuana drugs, found in 'herbal incense,' are mere chemical tweaks of each other, allowing them to escape detection each time researchers develop a new test for one of the compounds. Now chemists have developed a method that can screen for multiple designer drugs at once, without knowing their structures. The test may help law enforcement crack down on the substances. The researchers used a technique called 'mass defect filtering,' which can detect related compounds all at once. That's because related compounds have almost equal numbers to the right of the decimal point in their molecular masses. The researchers tested their technique on 32 herbal products ... They found that every product contained one or more synthetic cannabinoid; all told, they identified nine different compounds in them — two illegal ones and seven that are not regulated. The original paper appears (behind a paywall) in Analytical Chemistry." From the article: "The research is timely, too. 'Many drugs of abuse in the Olympics are designer drugs,' he [Gary Siuzdak] says, in the steroid family. Grabenauer plans to extend her method to other designer drug families."

John3 writes "For the past 15+ years I've maintained The Hardlines Digest (URL omitted to reduce the /. effect), an email discussion list for members of the retail hardware and lumber business. Since the beginning I've run the list on a Windows box running Lyris Listmanager, and it's worked admirably over the years. However, the list now has over 2,600 members and Listmanager doesn't have a nice web interface for users that like to read via their browser. Listmanager also doesn't handle attachments and HTML formatting well for the daily 'digest' version of the discussions. Finally, I'd really like to move hosting off-site so I don't need to maintain the server. The list members are hardware store owners and many are technically challenged, so I need to keep change to a minimum and make it easy for them to migrate. I've considered Google Groups and that seems to have most of the features I need. Are there any other low cost solutions for hosting a large discussion list?"
MojoKid writes "At the International Supercomputing Conference today, Intel announced that Knights corner, the company's first commercial Many Integrated Core product will ship commercially in 2012. The descendent of the processor formerly known as Larrabee also gets a new brand name — Xeon Phi. The idea behind Intel's new push is that the highly efficient Xeon E5 architecture (eight-core, 32nm Sandy Bridge) fuels the basic x86 cluster, while the Many Integrated Core CPUs that grew out of the failed Larrabee GPU offer unparalleled performance scaling and break new ground. The challenges Intel is trying to surmount are considerable. We've successfully pushed from teraflops to petaflops, but exaflops (or exascale computing) currently demands more processors and power than it's feasible to provide in the next 5-7 years. Intel's MIC is targeted at hammering away at that barrier and create new opportunities for supercomputing deployments."
itwbennett writes "With the much-acclaimed Galaxy SIII in its pocket, don't think that Samsung is looking at Amazon's success with the Kindle and Apple's success with its iOS devices and saying to themselves, 'No, we'd rather not have that kind of diverse revenue, we'll stick to razor-thin hardware margins,' writes blogger Kevin Purdy. And that's not the only reason that Samsung might decide the time is right to maintain its own OS, or at least an Android fork: There's also the looming spectre of Google-Motorola."
MrSeb writes "With the ISC (International Supercomputer Conference) kicking off this week, there's been a flurry of announcements around new supercomputer buildouts. One of the more interesting systems debuting this week is SuperMUC — IBM's new supercomputer at the Leibniz Supercomputing Center in Germany IBM is billing SuperMUC as the first 'hot-water cooled supercomputer,' an advance it claims cut power consumption by 40%. Dubbed Aquasar, the new system looks like any standard water cooler: water is pumped in one side of the blade, circulates throughout the system, and is pumped out. The difference, according to IBM, are the microchannels etched into the copper heatblock above the CPU cores. Rather than simply being dumped, SuperMUC's waste heat is designed to be converted into building heat during winter. Presumably it is mostly radiated away in summer, rather than being dumped into the offices of angry German scientists."
coondoggie writes "The Federal Aviation Administration (FAA) and NASA today said they signed an agreement to coordinate standards for commercial space travel of government and non-government astronauts to and from low-Earth orbit and the International Space Station (ISS). The main goals of the agreement are to establish a framework for the emerging commercial US space industry to help streamline requirements and multiple sets of standards and ultimately to regulate public and crew safety."
First time accepted submitter crtitheories writes "In response to the national kill list revealed by the New York Times a few weeks ago, an online "Do Not Kill" Registry has been launched where users can sign up to avoid being mistakenly added. From the Do Not Kill website: 'Through an active collaboration between the Do not Kill Registry, the brave pilots and operators of the U.S. drone program, and the American public, we believe that we can find the political and moral solutions needed to both protect the security of the United States while also satisfying the concerns of the broader global community'.

benrothke writes "In Digital Vertigo: How Todays Online Social Revolution Is Dividing, Diminishing, and Disorienting Us, author Andrew Keen, who describes himself as the Anti-Christ of Silicon Valley (whatever that means), raises numerous profound questions about social media and its implications on society. In the new world of social media and Web 3.0, which is claiming to revolutionize communication and interactions, Keen writes that history is repeating itself and points to the beginning of the industrial revolution as an example. He writes of Jeremy Bentham who invented the Panopticon; a structure where the inhabitants were watched at all times. Bentham felt the Panopticon could make humanity more virtuous, more hard-working and happier; similar to the promise of Web 3.0. The Panopticon was a failure, and Keen sees the same for Web 3.0. The book is a critique of Web 3.0." Read below for the rest of Ben's review.
AlistairCharlton writes with a story about an Android Face unlock security system that could use some tweaking. "Android's Face Unlock security on the Samsung Galaxy S3 can be tricked into unlocking the phone by showing it a photograph of the owner. In a test carried out by IBTimes UK, we found that the Galaxy S3 cannot distinguish between a photograph and a real person, leading us to suggest users should select a more secure way of locking the phone, such as with a PIN or password."
dartttt writes "After more than 14,000 votes by Linux users and efforts by Brian Fargo, Unity has added Linux support to their popular 3D game engine. Starting with Unity 4.0, Linux will be supported as a publishing platform allowing Unity games to be played natively on Linux. Only standalone desktop games will be supported initially. From the article: 'Unity Technologies, maker of a widely used video-game engine, today announced that its fourth-generation product will introduce new animation technology and extend its support for Adobe Systems' Flash Player, Linux, and Microsoft's DirectX 11.'"
rbowen writes "The software that powers the SourceForge developer tools (SourceForge is owned by the same corporate overlords as Slashdot) has been submitted to the Apache Software Foundation Incubator. The SourceForge Blog reads: 'By submitting Allura to the Apache Incubator, we hope to draw an even wider community of developers who can advance the feature set and tailor the framework to their needs. With the flexibility and extensibility Allura allows, developers are free to use any number of the popular source code management tools, including: Git, SVN, or Mercurial. We are indeed willing to turn our own open source platform into a tool that everyone can use and extend, and we believe Apache is the best place to steward the process.'"
AZA43 writes "Tokyo police have arrested six men, including two IT executives and one former tech exec, in connection with an Android malware campaign that netted $265,000. The men created a piece of Android malware that they disguised as a video player and distributed through an adult website. The app stole personal information and attempted to extort money for data 'protection services.' The malware doesn't appear to be particularly sophisticated, but it convinced more than 200 horny Japanese dudes to shell out $1200 each. And the arrests are one of, if not the, first time a major police force brought down criminals who used Android malware to extort a significant chunk of cash."
Harperdog writes "Laura Kahn has a great article about the long and fascinating history of do-it-yourself research, from Darwin and Mendel to present day. From the article: 'Welcome to the new millennium of do-it-yourself (DIY) biology. Advances in technology in the twenty-first century have enabled anybody, with the desire and the disposable income, to build rather sophisticated laboratories in their own homes. Entire communities have even materialized to promote these efforts -- like the thousands of amateur biologists who contribute to DIYbio.org, a website "dedicated to making biology an accessible pursuit for citizen scientists, amateur biologists and biological engineers."'"
kodiaktau writes "Film makers keep touting increased frame per second rate as improving viewing and cinema experience, however the number of theaters who actually have the equipment that can play the higher rate film is limited. It makes me wonder if this is in the real interest of creating a better experience and art, or if it is a ploy by the media manufacturers to sell more expensive equipment and drive ticket prices up. From the article: 'Warner Bros. showed 10 minutes of 3D footage from The Hobbit: An Unexpected Journey at 48 frames per second at CinemaCon earlier this year, and Jackson said in a videotaped message there that he hoped his movie could be played in 48fps in “as many cinemas as possible” when it opens in December. But exhibitors must pay the cost of the additional equipment, and some have wondered how much of a ticket premium they would charge to offset that cost.'"
Dexter Herbivore writes "A lot of Australian gamers are saying, 'finally' as legislation passed parliament to support the introduction of a R-18+ category for games. From the article: 'Jason Clare, the Minister for Home Affairs has just announced that R18+ for games is set to become a reality, after legislation successfully passing through the Federal Parliament, having just gone through the Senate without amendment.'"
