sfcrazy writes "The newly formed company has opened the next chapter of its history by bagging $23 million financing from A16Z (Andreessen Horowitz). CyanogenMod was recently incorporated as a company after getting Benchmark Capital and Redpoint Ventures as partners and raising $7 million in funding."
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 anonymous reader writes "Gates fulfilled a Reddit users wish-list by buying several items and donating to a listed charity organization, although he did pass on getting the iPad on the list. From the article: 'The true identity of Rachel's Secret Santa was finally revealed when she found a photo of Gates holding the stuffed animal and the signed donation sent to Heifer International. 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.'"
SonicSpike writes with a story about the huge amount of bitcoins owned by the FBI. "In September, the FBI shut down the Silk Road online drug marketplace, and it started seizing bitcoins belonging to the Dread Pirate Roberts — the operator of the illicit online marketplace, who they say is an American man named Ross Ulbricht. The seizure sparked an ongoing public discussion about the future of Bitcoin, the world's most popular digital currency, but it had an unforeseen side-effect: It made the FBI the holder of the world's biggest Bitcoin wallet. The FBI now controls more than 144,000 bitcoins that reside at a bitcoin address that consolidates much of the seized Silk Road bitcoins. Those 144,000 bitcoins are worth close to $100 million at Tuesday's exchange rates. Another address, containing Silk Road funds seized earlier by the FBI, contains nearly 30,000 bitcoins ($20 million)."

alphadogg writes "Engineers are putting the final touches on a network capable of handling up to 54Tbps of traffic when the Winter Olympics opens on Feb. 7 in the Russian city of Sochi. The two locations where the Olympics will take place — the Olympic village in Sochi and a tight cluster of Alpine venues in the nearby Krasnaya Polyana Mountains — are completely new construction, so this project represents a greenfield environment for Avaya, the company heading up the project. In addition to investing in a telecom infrastructure, Russia is spending billions of dollars to upgrade Sochi's electric power grid, its transportation system and even its sewage treatment facilities."
sciencehabit writes "How old is the binary number system? Perhaps far older than the invention of binary math in the West. The residents of a tiny Polynesian island may have been doing calculations in binary—a number system with only two digits—centuries before it was described by Gottfried Leibniz, the co-inventor of calculus, in 1703."
