New submitter rvalles writes "Xiph.org just released a major update to their Opus audio codec. Opus 1.1 offers major improvements over last year's 1.0.2 release. Opus is a general-purpose, very flexible, open and royalty-free audio codec that offers low-latency and high quality/bitrate, incorporating technology from Skype's SILK codec and Xiph.Org's CELT codec. Its first release beat everything else last year at 64kbit/s in a listening test held at HydrogenAudio."

KentuckyFC writes "The early symptoms of many diseases show up first in the smallest blood vessels, but imaging the fine structure of these vessels is a tricky problem for medics. The most common way is to inject them with a contrast agent and use x-ray tomography to create a 3D image of their structure. This shows problems in the large vessels but not smaller ones. The problem is the lack of contrast. Conventional contrast agents are based on iodine, which has a high electron density and so better absorbs x-rays than other atoms. But a better solution would be to use a higher density fluid, such as a liquid metal. The obvious fears associated with toxicity and so forth mean this has never been tried. Until now. A team of Chinese biomedical engineers have created the world's first images of a pig's heart injected with gallium. This has a melting point of 29 degrees C, so it's a liquid at body temperature. And the results show the detailed structure of the tiniest blood vessels, revealing capillaries just 0.07 mm in diameter. That's significantly more detailed than is possible with iodine-based contrast agents. An important question is whether this technique will ever be possible in humans. The Chinese team seems optimistic. They say gallium is chemically inert, non-toxic to humans and can be injected and sucked out without leaving a residue. 'It suggests the possibility for localized in vivo vascular-enhanced radiological imaging in the near future.'"
walterbyrd writes "Streaming services are ailing. Pandora, the giant of its class and the survivor at 13 years old, is waging an ugly war to pay artists and labels less in order to stay afloat. Spotify, in spite of 6 million paid users and 18 million subscribers who humor some ads in their stream, has yet to turn a profit. Rhapsody axed 15% of its workforce right as Apple's iTunes Radio hit the scene. On-demand competitor Rdio just opted for layoffs too, in order to move into a 'scalable business model.' Did no one wonder about that business-model bit in the beginning? Meanwhile, Turntable.fm, a comparatively tiny competitor with what should have been viral DNA, just pulled the plug on its virtual jam sessions this week—and it just might be the canary in the coal mine."
chicksdaddy writes "The Federal Trade Commission announced on Thursday that it settled with the maker of 'Brightest Flashlight Free,' a popular Android mobile application, over charges that the company used deceptive advertising to collect location and device information from Android owners. The FTC says the company failed to disclose wanton harvesting and sharing of customers' locations and mobile device identities with third parties. Brightest Flashlight Free, which allows Android owners to use their phone as a flashlight, is a top download from Google Play, the main Android marketplace. Statistics from the site indicate that it has been downloaded more than one million times with an overall rating of 4.8 out of 5 stars. The application, which is available for free, displays mobile advertisements on the devices it is installed on. However, the device also harvested a wide range of data from Android phones which was shared with advertisers, including what the FTC describes as 'precise geolocation along with persistent device identifiers.' As part of the settlement with the FTC, Goldenshores is ordered to change its advertisements and in-app disclosures to make explicit any collection of geolocation information, how it is or may be used, the reason for collecting location information and which third parties that data is shared with."
Kristian vonBengtson writes "Wanna build your own space capsule capable of doing an atmospheric re-entry on a suborbital mission? Well, here are some production hints and a visual guide." The initial stages begin with sketches on paper before moving to 3D design software. He writes, "A whole bunch of sketches were done to get some kind of initial idea of the size, subsystems layout and how to actually produce the capsule while keeping an open structure for further development and potential changes. One of the main concerns was the small size and the ability to easy install and replace avionics. This led to the decision that all external side panels will have to accommodate being taken on and off – no welding, only on the main structure." Afterward, he moves on to show the final metal cuts and how the pieces are put together via bolts and welding.
An anonymous reader writes "Microsoft announced yesterday their plans to encrypt customer data to prevent government snooping. Free Software Foundation executive director John Sullivan questions the logic of trusting non-free software, regardless of promises or even intent. He says, 'Microsoft has made renewed security promises before. In the end, these promises are meaningless. Proprietary software like Windows is fundamentally insecure not because of Microsoft's privacy policies but because its code is hidden from the very users whose interests it is supposed to secure. A lock on your own house to which you do not have the master key is not a security system, it is a jail. ... If the NSA revelations have taught us anything, it is that journalists, governments, schools, advocacy organizations, companies, and individuals, must be using operating systems whose code can be reviewed and modified without Microsoft or any other third party's blessing. When we don't have that, back doors and privacy violations are inevitable.'"
Hugh Pickens DOT Com writes "Josh Gerstein writes on Politico that President Barack Obama told Chris Matthews in an interview recorded for MSNBC's 'Hardball' that he'll be reining in some of the snooping conducted by the NSA, but he did not detail what new limits he plans to impose on the embattled spy organization. 'I'll be proposing some self-restraint on the NSA. And...to initiate some reforms that can give people more confidence,' said the President who insisted that the NSA's work shows respect for the rights of Americans, while conceding that its activities are often more intrusive when it comes to foreigners communicating overseas. 'The NSA actually does a very good job about not engaging in domestic surveillance, not reading people's emails, not listening to the contents of their phone calls. Outside of our borders, the NSA's more aggressive. It's not constrained by laws.' During the program, Matthews raised the surveillance issue by noting a Washington Post report on NSA gathering of location data on billion of cell phones overseas. 'Young people, rightly, are sensitive to the needs to preserve their privacy and to retain internet freedom. And by the way, so am I,' responded the President. 'That's part of not just our First Amendment rights and expectations in this country, but it's particularly something that young people care about, because they spend so much time texting and-- you know, Instagramming.' With some at the NSA feeling hung out to dry by the president, Obama also went out of his way to praise the agency's personnel for their discretion. 'I want to everybody to be clear: the people at the NSA, generally, are looking out for the safety of the American people. They are not interested in reading your emails. They're not interested in reading your text messages. And that's not something that's done. And we've got a big system of checks and balances, including the courts and Congress, who have the capacity to prevent that from happening.'"
sciencehabit writes "Many physicians and parents report that their autistic children have unusually severe gastrointestinal problems, such as chronic constipation or diarrhea. These observations have led some researchers to speculate that an ailing gut contributes to the disorder in some cases, but scientific data has been lacking. Now, a provocative study claims that a probiotic treatment for gastrointestinal issues can reduce autismlike symptoms in mice and suggests that this treatment could work for humans, too."
Diamonddavej writes "TorrentFreak reports a potentially troubling court decision in Germany. The company Appwork has been threatened with a 250,000 Euro fine for functionality committed to its open-source downloader (JDownloader2) repository by a volunteer coder without Appwork's knowledge. The infringing code enables downloading of RTMPE video streams (an encrypted streaming video format developed by Adobe). Since the code decrypted the video streams, the Hamburg Regional Court decided it represented circumvention of an 'effective technological measure' under Section 95a of Germany's Copyright Act and it threatened Appwork with a fine for 'production, distribution and possession' of an 'illegal' piece of software."

Nerval's Lobster writes "Bank of America has issued a research report suggesting that the crypto-currency Bitcoin could become 'a major means of payment for e-commerce' on its way to emerging as 'a serious competitor to traditional money transfer providers.' The bank attaches a 'maximum market capitalization' of Bitcoin at roughly $1,300, based on its position as a 'major player in both e-commerce and money transfer' as well as 'a significant store of value with a reputation close to silver.' Bitcoin has come close to exceeding that theoretical ceiling in recent weeks, although its valuation dove today after the People's Bank of China decided to declare it a volatile 'currency' without real legal status; that financial institution is also concerned about its use in money laundering and black markets. Bank of America sees Bitcoins' advantages as low transaction costs, its finite supply (which will protect its value), and its increasing attractiveness as an alternative to 'traditional' cash. As with the People's Bank of China, however, the bank sees the currency's extreme volatility and lack of legal backing as a bad thing, and frowns at the possibility that regulators could step in and increase transaction costs. 'A 50 minute wait before payment receipt confirmation is received will prohibit wider use,' the report adds. 'This is less of an issue for two parties that know each other because they trust the other will not double spend, but when dealing with an anonymous counterparty this creates a high level of unhedgeable risk.' Without a 'central counterparty' to verify transactions and thus mitigate that risk, Bitcoin could fail to break into wider use."
itwbennett writes "Broadcom Chairman and CTO Henry Samueli has some bad news for you: Moore's Law isn't making chips cheaper anymore because it now requires complicated manufacturing techniques that are so expensive they cancel out the cost savings. Instead of getting more speed, less power consumption and lower cost with each generation, chip makers now have to choose two out of three, Samueli said. He pointed to new techniques such as High-K Metal Gate and FinFET, which have been used in recent years to achieve new so-called process nodes. The most advanced process node on the market, defined by the size of the features on a chip, is due to reach 14 nanometers next year. At levels like that, chip makers need more than traditional manufacturing techniques to achieve the high density, Samueli said. The more dense chips get, the more expensive it will be to make them, he said."
Taco Cowboy writes "NASA's WISE (Wide-field Infrared Survey Explorer) satellite was looking at a distant galaxy, some 3.8 billion light-years away, and saw something rather unusual. At first they thought that they saw a galaxy was forming new stars at a furious rate, but upon closer checking, they found that they were seeing two supermassive black holes spiraling closer and closer to each other. The dance of this black hole duo started out slowly, with the objects circling each other at a distance of about a few thousand light-years. As the black holes continued to spiral in toward each other, they were separated by just a few light-years. Supermassive black holes at the cores of galaxies typically shoot out pencil-straight jets, but in this case, the jet showed a zig-zag pattern. According to the scientists, a second massive black hole could, in essence, be pushing its weight around to change the shape of the other black hole's jet. Visible-light spectral data from the Gemini South telescope in Chile showed similar signs of abnormalities, thought to be the result of one black hole causing disk material surrounding the other black hole to clump. Together, these and other signs point to what is probably a fairly close-knit set of circling black holes, though the scientists can't say for sure how much distance separates them."
schliz writes "Stanford scientists say they could help boost people's motivation to overcome difficulties by electrically stimulating the anterior midcingulate cortex in the brain. The study involved two patients, who described the 'will to persevere' beautifully. One said it was like driving into a storm front and knowing that he had to get through. From the article: 'Stanford University neuroscientists passed a small current through an area in the part of the brain that deals with error detection, anticipation of tasks, attention, motivation, and emotional responses. Both patients involved in the study had epilepsy, and already had electrodes implanted in their brains to help doctors learn about the source of their seizures."
Velcroman1 writes "A U.S. spacecraft hasn't made a controlled landing on the moon since Apollo 17 left the lunar surface on Dec. 14, 1972. That's about to change. Moon Express will unveil the MX-1 spacecraft at the Autodesk University show in Las Vegas Thursday evening — a micro-spacecraft that will in 2015 mark the first U.S. 'soft' landing since the days of the Apollo program, FoxNews.com has learned. The craft looks for all the world like a pair of donuts wearing an ice cream cone, and the tiny vehicle clearly isn't big enough for a human being. But it is big enough to scoop up some rocks and dirt, store them in an internal compartment, and return it to Earth. After all, the moondirt Gene Cernan, Neil Armstrong and Buzz Aldrin once trod holds a king's ransom of titanium, platinum, and other rare elements. Moon Express plans to mine it."
