Lucas123 writes "Solid Concepts, which last month revealed the first fully-functional, metal 3D gun, announced today that they're putting 100 limited-edition models of the 1911 .45 caliber pistol on sale for $11,900 each. Solid Concept demonstrated the gun by initially firing 50 rounds through it. Since then, the company said it has fired nearly 2,000 rounds through the pistol without a single malfunction. Unlike the very first 3D printed gun — the single-shot, plastic Liberator — Solid Concepts says is not trying to promote the right to bear arms under the Second Amendment. Its purpose in printing the firearm was to demonstrate its ability to turn out precision, durable parts that could withstand the massive pressure created by firing a bullet. People who purchase one of the limited-edition guns will also have the chance to tour Solid Concept's Texas facility to see their gun being printed, and to join their lead additive manufacturing engineers on the range for the first test firing of their limited 1911 gun."
Hugh Pickens DOT Com writes "Jacob Kastrenakes reports on The Verge that as part a response to the NSA's wide-reaching surveillance programs, BitTorrent is unveiling a secure messaging service that will use public key encryption, forward secrecy, and a distributed hash table so that chats will be individually encrypted and won't be stored on some company's server. 'It's become increasingly clear that we need to devote hackathons, hours and resources to developing a messaging app that protects user privacy,' says Christian Averill, BitTorrent's director of communications. Because most current chat services rely on central servers to facilitate the exchange of messages, 'they're vulnerable: to hackers, to NSA dragnet surveillance sweeps.' BitTorrent chat aims to avoid those vulnerabilities through its encryption methods and decentralized infrastructure. Rather than checking in with one specific server, users of BitTorrent chat will collectively help each other figure out where to route messages to. In order to get started chatting, you'll just need to give someone else your public key — effectively your identifier. Exchanging public keys doesn't sound like the simplest way to begin a chat, but Averill says that BitTorrent hopes to make it easy enough for anyone interested. 'What we're going to do is to make sure there are options for how this is set up,' says Averill. 'This way it will appeal to the more privacy conscious consumer as well as the less technically inclined.' For now, it remains in a private testing phase that interested users can apply for access to. There's no word on when it'll be open to everyone, but with all of the recent surveillance revelations, it's easy to imagine that some people will be eager to get started."
cold fjord writes "UPI reports, 'Eighty percent of scientific data are lost within two decades, disappearing into old email addresses and obsolete storage devices, a Canadian study (abstract, article paywalled) indicated. The finding comes from a study tracking the accessibility of scientific data over time, conducted at the University of British Columbia. Researchers attempted to collect original research data from a random set of 516 studies published between 1991 and 2011. While all data sets were available two years after publication, the odds of obtaining the underlying data dropped by 17 per cent per year after that, they reported. "Publicly funded science generates an extraordinary amount of data each year," UBC visiting scholar Tim Vines said. "Much of these data are unique to a time and place, and is thus irreplaceable, and many other data sets are expensive to regenerate.' — More at The Vancouver Sun and Smithsonian."
astroengine writes "New measurements of the electron have confirmed, to the smallest precision attainable, that it has a perfect roundness. This may sounds nice for the little electron, but to one of the big physics theories beyond the standard model, it's very bad news. 'We know the Standard Model does not encompass everything,' said physicist David DeMille, of Yale University and the ACME collaboration, in a press release. 'Like our LHC colleagues, we're trying to see something in the lab that's different from what the Standard Model predicts.' Should supersymmetrical particles exist, they should have a measurable effect on the electron's dipole moment. But as ACME's precise measurements show, the electron still has zero dipole moment (as predicted by the standard model) and is likely very close to being perfectly round. Unfortunately for the theory of supersymmetry, this is yet another blow."
Esther Schindler writes "It's certainly fun to pretend to find work inspiration from our favorite SF films. That's what Carol Pinchefsky does in two posts, one about positive business lessons you can take away from SF films (such as 'agile thinking can save many a project (and project manager) in a crisis' from Robocop and team motivation lessons from Buffy), and the other, 5 Project Management Horror Stories Found in Sci-Fi Movies, with examples of the impact of poor documentation on Captain America."

cartechboy writes "Two guys have made a life-sized Lego car that runs on air. That's right, the 256-piston, air-powered Lego working vehicle built with half a million black and yellow Lego pieces can actually be driven up to 18 mph. It was designed and built by 20-year-old Romanian Raul Oaida in 20 months after he and his partner, Australia-based Steve Sammartino raised "tens of thousands" of crowdfunded dollars with their prospectus entitled quite simply: "Super Awesome Micro Project." The car was built in Romania and then moved to Melbourne, Australia (presumably not brick-by-brick.) In the video, the only visible non-Lego components are the gauges, wheel rims, and tires (though the wheels have Lego faces--literally.)"

An inscription in the book with a "really nice message" and note from Gates wishing Rachel a Merry Christmas and a Happy Birthday was the topper.'"
ckwu writes "The vast real estate of windows in office buildings and skyscrapers could be a fruitful field for harvesting solar energy—if lightweight solar cells could be made with a high enough conversion efficiency and appealing aesthetics. Now researchers at Oxford University report semitransparent solar cells that might do the trick. The team made solar cells using a perovskite, a class of mineral-like materials that have properties similar to inorganic semiconductors and show sunlight-to-electricity conversion efficiencies of more than 15%. The team deposited a thin film of perovskite onto glass so that the material formed tiny crystalline islands. The islands absorb photons and convert them to electrons, while light striking the empty areas passes through. The result was a semitransparent solar cell with a grayish tint."
jfruh writes "You may find it mildly creepy that Microsoft has a private police force, but the Digital Crimes Unit has helped real law enforcement do things like disrupt huge botnets. According to Richard Boscovich, assistant general counsel for the Digital Crimes Unit, Microsoft is only able to do all this by relying on the company's existing infrastructure, including its Azure cloud service. The DCU can provision compute time from the cloud as necessary to combat complex threats, he said, and also uses cloud services to share information with law enforcement agencies quickly."
Nerval's Lobster writes "The comparatively recent addition of supercomputing to the toolbox of biomedical research may already have paid off in a big way: Researchers have used a bio-specialized supercomputer to identify a molecular 'switch' that might be used to turn off bad behavior by pathogens. They're now trying to figure out what to do with that discovery by running even bigger tests on the world's second-most-powerful supercomputer. The 'switch' is a pair of amino acids called Phe396 that helps control the ability of the E. coli bacteria to move under its own power. Phe396 sits on a chemoreceptor that extends through the cell wall, so it can pass information about changes in the local environment to proteins on the inside of the cell. Its role was discovered by a team of researchers from the University of Tennessee and the ORNL Joint Institute for Computational Sciences using a specialized supercomputer called Anton, which was built specifically to simulate biomolecular interactions among proteins and other molecules to give researchers a better way to study details of how molecules interact. 'For decades proteins have been viewed as static molecules, and almost everything we know about them comes from static images, such as those produced with X-ray crystallography,' according to Igor Zhulin, a researcher at ORNL and professor of microbiology at UT, in whose lab the discovery was made. 'But signaling is a dynamic process, which is difficult to fully understand using only snapshots.'"
toshikodo writes "The BBC is reporting that Internet content filters being rolled out by major ISPs in the UK are failing to allow access to acceptable content, such as sex education and sexual abuse advise sites, while also still allowing access to porn. According to the article, 'TalkTalk's filter is endorsed by Mr Cameron but it failed to block 7% of the 68 pornographic websites tested by Newsnight.' The ISPs claim that it is impossible for their filters to be 100% accurate, and that they are working with their users to improve quality. I wonder how long it will be before one of these filters blocks access to the Conservative Party's website, and what will Cameron do then?"
wiredmikey writes "A board set up to review the NSA's vast surveillance programs has called for a wide-ranging overhaul of National Security Agency practices while preserving 'robust' intelligence capabilities. The panel, set up by President Obama, issued 46 recommendations, including reforms at a secret national security court and an end to retention of telephone 'metadata' by the spy agency. The 308-page report (PDF) submitted last week to the White House and released publicly Wednesday says the US government needs to balance the interests of national security and intelligence gathering with privacy and 'protecting democracy, civil liberties, and the rule of law.' Panel members said the recommendations would not necessarily mean a rolling back of intelligence gathering, including on foreign leaders, but that surveillance must be guided by standards and by high-level policymakers."
sciencehabit writes "In a report on the most complete genome of a Neandertal ever sequenced, an international team of researchers has found that the parents of a Neandertal woman from Siberia were as closely related as half-siblings. The genome also shows that at some point the Neandertals interbred with other human groups, including their cousins the Denisovans, and our own modern human ancestors. There are even signs of Denisovans interbreeding with a mysterious archaic species. In all, the study suggests very close encounters among the several kinds of hominins living in the past 125,000 years. The detailed genome of the extinct Neandertals—our closest relatives—also offers a new look at the genetic differences that set our species apart from all the others."
coondoggie writes "In its annual look at what challenges NASA faces in the coming year, the agency's Office of the Inspector General (OIG) this year outlined nine key areas it says will cause the most angina. Leading the way in pain is money. NASA's current money story starts off bad and just gets worse. From the article: '"Along with the rest of the Federal Government, NASA began FY 2013 under a 6-month continuing resolution that funded the Agency at FY 2012 levels. This was followed by a budget for the remainder of the fiscal year that reduced the Agency's enacted funding level of $17. 5 billion by $626.5 million, or approximately 4% due to sequestration. These financial pressures look to repeat themselves in FY 2014, with no annual budget in place at the beginning of the fiscal year and potential sequestration impacts that could reduce NASA's budget request of $17.7 billion by $1.5 billion to $16.2 billion. As the National Research Council noted in its 2012 report examining NASA's strategic direction and management, NASA's budget is 'mismatched to the current portfolio of missions, facilities, and staff,'" the OIG report stated.'"
