SchrodingerZ writes "The Defense Advanced Research Projects Agency (DARPA) is known for making odd scientific advances ranging from hypersonic unnamed rockets to bionic prosthetic limbs to insect-sized reconnaissance drones. But recently DARPA has made a interesting advancement in the field of fire suppression. Using two speakers arranged on either side of an open liquid fuel flame, an acoustic field was emitted and engulfed the fire. 'The sound increases air velocity, which then thins the area of the flame where combustion occurs, known as the flame boundary.' This make the flame weak and much easier to douse. Another wonderful thing about this: it's not even that loud! DARPA began its testing in 2008, stating that despite extensive research in this area, there have been no new methods for extinguishing and/or manipulating fire in almost 50 years. The agency plans to expand on this experiment and try to make it successful on a practical scale."

First time accepted submitter rosy rohangi writes "Biologists at UC San Diego have discovered a chemical that provides a completely new direction and promise for the development of drugs to treat metabolic disorders such as type 2 diabetes – a key concern of public health in the U.S. due to the current obesity epidemic. From the article: '...Scientists have long suspected that diabetes and obesity could be related to problems of the biological clock. Laboratory mice with altered biological clocks, for example, often become obese and develop diabetes. Two years ago, a team led by Steve Kay, dean of the Division of Biological Sciences at UC San Diego, discovered the first biochemical link between the biological clock and diabetes. He found that a key protein, cryptochrome, which regulates the biological clocks of plants, insects and mammals also regulates glucose production in the liver and that changes in levels of this protein could improve the health of diabetic mice.'"

hypnosec writes "A specially designed smartphone for the visually impaired or partially sighted has been launched in the UK. The device, dubbed Georgie, has many special features including a voice-assisted touch screen and apps that will allow for easy completion of day-to-day tasks like catching a bus, reading printed text and pinpointing a location. Designed by a blind couple, Roger and Margaret Wilson-Hinds, and named after Mrs Wilson-Hind's guide dog, the smartphone is powered by the Android operating system and uses handsets like Samsung XCover and Galaxy Ace 2, notes the BBC. The main reason for developing such a phone, according to the couple, was that they wanted to get the technology across to people with very little or no sight. 'It's exactly the type of digital experience we want to make easily available to people with little or no sight,' said Roger."

astroengine writes "If the Pluto-Charon system were viewed in a similar way to binary stars and binary asteroids, Pluto would become a Pluto-Charon binary planet. After all, Charon is 12% the mass of Pluto, causing the duo to orbit a barycenter that is located above Pluto's surface. Sadly, in the IAU's haste to define what a planet is in 2006, they missed a golden opportunity to define the planetary binary. Interestingly, if Pluto was a binary planet, last week's discovery of a fifth Plutonian moon would have in fact been the binary's fourth moon to be discovered by Hubble — under the binary definition, Charon wouldn't be classified as a moon at all."

Hugh Pickens writes "According to Alan D. Mutter, after a 50% drop in newspaper advertising since 2005, the old ways of running a newspaper can no longer succeed, so most publishers are faced with choosing the best possible strategy going-forward for their mature but declining businesses: farm it, feed it, or milk it. Warren Buffett is farming it, and recently bucked the widespread pessimism about the future of newspapers by buying 63 titles from Media General. He is concentrating on small and medium papers in defensible markets, while steering clear of metro markets, where costs are high and competition is fierce. 'I do not have any secret sauce,' says Buffett. 'There are still 1,400 daily papers in the United States. The nice thing about it is that somebody can think about the best answer and we can copy him. Two or three years from now, you'll see a much better-defined pattern of operations online and in print by papers.' Advance Publications is milking it by cutting staff and reducing print publication to three days a week at the New Orleans Times-Picayune, thus making the Crescent City the largest American metropolis to be deprived of a daily dose of wood fiber in its news diet. Once dismantled, the local reporting infrastructure in communities like New Orleans will almost certainly never be rebuilt. 'By cutting staff to a bare minimum and printing only on the days it is profitable to do so, publishers can milk considerable sums from their franchises until the day these once-indomitable cash cows go dry.' Rupert Murdoch is feeding it as he spins his newspapers out of News Corp. and into a separate company empowered to innovate the traditional publishing businesses into the future. In various interviews after announcing the planned spinoff, Murdoch promised to launch the new company with no debt and ample cash to aggressively pursue digital publishing opportunities across a variety of platforms. 'If the spinoff materializes in anywhere near the way Murdoch is spinning it, however, it could turn out to be a model for iterating the way forward for newspapers.'"

First time accepted submitter cjsm writes "James and Janet Baker were the inventors of Dragon Systems' speech recognition software, and after years of work, they created a multimillion dollar company. At the height of the tech boom, with investment offers rolling in, they turned to Goldman Sachs for financial advice. For a five million dollar fee, Goldman hooked them up with Lernout & Hauspie, the Belgium speech recognition company. After consultations with Goldman Sachs, the Bakers traded their company for $580 million in Lernout & Hauspie stock. But it turned out Lernout & Hauspie was involved in cooking their books and went bankrupt. Dragon was sold in a bankruptcy auction to Scansoft, and the Bakers lost everything. Goldman and Sachs itself had decided against investing in Lernout & Hauspie two years previous to this because they were lying about their Asian sales. The Bakers are suing for one billion dollars."

First time accepted submitter transporter_ii writes "A compressed air energy storage (CAES) plant was first built in Germany in 1978, but East Texas will be the site of one of the world's first modern CAES plants. How does it work? A CAES power generation facility uses electric motor-driven compressors (generated by natural gas generators) to inject air into an underground storage cavern and later releases the compressed air to turn turbines and generate electricity back onto the grid, according to the plants owner. The location near Palestine, Texas was selected because of its large salt dome, which will be used to store the compressed air. The plant is estimated to cost $350 million-plus, and will create about 20 to 25 permanent jobs."

Harperdog writes "Paul N. Edwards has a great paper about the links between nuclear weapons testing and climate science. From the abstract: 'Tracing radioactive carbon as it cycles through the atmosphere, the oceans, and the biosphere has been crucial to understanding anthropogenic climate change. The earliest global climate models relied on numerical methods very similar to those developed by nuclear weapons designers for solving the fluid dynamics equations needed to analyze shock waves produced in nuclear explosions. The climatic consequences of nuclear war also represent a major historical intersection between climate science and nuclear affairs. Without the work done by nuclear weapons designers and testers, scientists would know much less than they now do about the atmosphere. In particular, this research has contributed enormously to knowledge about both carbon dioxide, which raises Earth's temperature, and aerosols, which lower it.'"

Diggester writes "Asteroids from the inner solar system are the most likely source of the majority of Earth's water, a new study suggests. The results contradict prevailing theories, which hold that most of our planet's water originated in the outer solar system and was delivered by comets or asteroids that coalesced beyond Jupiter's orbit, then migrated inward."

theodp writes "Last July, Slashdot reported on Kyle McDonald, the artist who had the Secret Service raid his home at the behest of Apple, who was miffed with Kyle's surreptitious capture of people's expressions as they stared at computers in Apple Stores. A year later, Wired is running McDonald's first-person account of the preparation for and fallout from his People Staring at Computers project. 'I really wasn't expecting the Secret Service,' McDonald begins. 'Maybe an email, or a phone call from Apple. Instead, my first indication that something was "wrong" was a real-life visit from the organization best known for protecting the President of the United States of America.'"

NotSanguine writes in with a story about a review of the forensic evidence in thousands of criminal cases to see if any defendants were wrongly convicted. "The Justice Department and the FBI have launched a review of thousands of criminal cases to determine whether any defendants were wrongly convicted or deserve a new trial because of flawed forensic evidence, officials said Tuesday. The undertaking is the largest post-conviction review ever done by the FBI. It will include cases conducted by all FBI Laboratory hair and fiber examiners since at least 1985 and may reach earlier if records are available, people familiar with the process said. Such FBI examinations have taken place in federal and local cases across the country, often in violent crimes, such as rape, murder and robbery."

An anonymous reader writes "How far would a Star Wars fan go to preserve a relic from the iconic film series? One devoted fan traveled to Tunisia to rescue Luke Skywalker's boyhood home, also known as The Lars Homestead, as seen in Star Wars Episode IV: A New Hope. On a trip to Tunisia in 2010, Belgian traveler Mark Dermul came upon the modest dome-shaped hut that George Lucas built in the mid-1970s to serve as Luke Skywalker's home. The structure was falling apart when Dermul found it, so he hatched a scheme to restore it. After two years and a lot of cement and plaster, Luke's house is looking better than ever."

MrSeb writes "Mechanical engineers and roboticists working at MIT have developed an intelligent automobile co-pilot that sits in the background and only interferes if you're about to have an accident. If you fall asleep, for example, the co-pilot activates and keeps you on the road until you wake up again. Like other autonomous and semi-autonomous solutions, the MIT co-pilot uses an on-board camera and laser rangefinder to identify obstacles. These obstacles are then combined with various data points — such as the driver's performance, and the car's speed, stability, and physical characteristics — to create constraints. The co-pilot stays completely silent unless you come close to breaking one of these constraints — which might be as simple as a car in front braking quickly, or as complex as taking a corner too quickly. When this happens, a ton of robotics under the hood take over, only passing back control to the driver when the car is safe. This intelligent co-pilot is starkly contrasted with Google's self-driving cars, which are completely computer-controlled unless you lean forward, put your hands on the wheel, and take over. Which method is better? A computer backup, or a human backup? I'm not sure."

Phoghat writes "A top defense and cybersecurity expert says the U.S. should stop trying to take aim at expert hackers and start doing a better job of recruiting them. 'Let's just say that in some places you find guys with body piercings and nonregulation haircuts,' says U.S. Naval Postgraduate School professor John Arquilla . 'But most of these sorts of guys can't be vetted in the traditional way. We need a new institutional culture that allows us to reach out to them.'"
