An anonymous reader writes "High-temperature superconductors exhibit a frustratingly varied catalog of odd behavior, such as electrons that arrange themselves into stripes or refuse to arrange themselves symmetrically around atoms. Now two physicists propose that such behaviors – and superconductivity itself – can all be traced to a single starting point, and they explain why there are so many variations. Most subatomic particles have a tiny magnetic field – a property physicists call 'spin' – and electrical resistance happens when the fields of electrons carrying current interact with those of surrounding atoms. Two electrons can join like two bar magnets, the north pole of one clamping to the south pole of the other, and this 'Cooper pair' is magnetically neutral and can move without resistance. Lee and Davis propose that this 'antiferromagnetic' interaction is the universal cause not only for superconductivity but also for all the observed intertwined ordering. They show how their 'unified' theory can predict the phenomena observed in copper-based, iron-based and so-called 'heavy fermion' materials."
First time accepted submitter biodata writes "The BBC is reporting that hundreds of UK commercial air flights have been delayed for most of Saturday due to an internal telephone systems problem in the National Air Traffic Control Service, and delays are likely to continue into the evening. A spokesperson said that it was a different software bug from the one which grounded flights in the summer."
An anonymous reader writes "There's an interesting story on CNN about the University of Pennsylvania's human trial results on curing intractable cancer by retraining the patient's own immune system. Quoting: 'Nick Wilkins was diagnosed with leukemia when he was 4 years old, and when the cancer kept bouncing back, impervious to all the different treatments the doctors tried, his father sat him down for a talk. John Wilkins explained to Nick, who was by then 14, that doctors had tried chemotherapy, radiation, even a bone marrow transplant from his sister. ... A few months later, Nick traveled from his home in Virginia to Philadelphia to become a part of the experiment. This new therapy was decidedly different from the treatments he'd received before: Instead of attacking his cancer with poisons like chemotherapy and radiation, the Philadelphia doctors taught Nick's own immune cells to become more adept at killing the cancer. Two months later, he emerged cancer-free. It's been six months since Nick, now 15, received the personalized cell therapy, and doctors still can find no trace of leukemia in his system. ... Twenty-one other young people received the same treatment at The Children's Hospital of Philadelphia, and 18 of them, like Nick, went into complete remission -- one of them has been disease-free for 20 months.'"
stox tips an article from Nobel Week Dialogue about the biggest problem of the nuclear power industry: it's not fun anymore. The author, Ashutosh Jogalekar, expands upon this quote from Freeman Dyson: "The fundamental problem of the nuclear industry is not reactor safety, not waste disposal, not the dangers of nuclear proliferation, real though all these problems are. The fundamental problem of the industry is that nobody any longer has any fun building reactors. Sometime between 1960 and 1970 the fun went out of the business. The adventurers, the experimenters, the inventors, were driven out, and the accountants and managers took control. The accountants and managers decided that it was not cost effective to let bright people play with weird reactors." Jogalekar adds, "For any technological development to be possible, the technology needs to drive itself with the fuel of Darwinian innovation. It needs to generate all possible ideas – including the weird ones – and then fish out the best while ruthlessly weeding out the worst. ... Nothing like this happened with nuclear power. It was a technology whose development was dictated by a few prominent government and military officials and large organizations and straitjacketed within narrow constraints. ... The result was that the field remained both scientifically narrow and expensive. Even today there are only a handful of companies building and operating most of the world's reactors. To reinvigorate the promise of nuclear power to provide cheap energy to the world and combat climate change, the field needs to be infused with the same entrepreneurial spirit that pervaded the TRIGA design team and the Silicon Valley entrepreneurs."
New submitter krakman writes "The Washington Post has an interesting story about how the FBI can investigate and collect details from computers over the net, without knowing anything about the computer location. Here's an example of the FBI's network investigative techniques: 'The man who called himself "Mo" had dark hair, a foreign accent and — if the pictures he e-mailed to federal investigators could be believed — an Iranian military uniform. When he made a series of threats to detonate bombs at universities and airports across a wide swath of the United States last year, police had to scramble every time. Mo remained elusive for months, communicating via e-mail, video chat and an Internet-based phone service without revealing his true identity or location, court documents show. ... The FBI’s elite hacker team designed a piece of malicious software that was to be delivered secretly when Mo signed on to his Yahoo e-mail account, from any computer anywhere in the world, according to the documents. The goal of the software was to gather a range of information — Web sites he had visited and indicators of the location of the computer — that would allow investigators to find Mo and tie him to the bomb threats. ... Even though investigators suspected that Mo was in Iran, the uncertainty around his identity and location complicated the case. Had he turned out to be a U.S. citizen or a foreigner living within the country, a search conducted without a warrant could have jeopardized his prosecution. ...But, [a court document] said, Mo’s computer did send a request for information to the FBI computer, revealing two new IP addresses in the process. Both suggested that, as of last December, Mo was still in Tehran.'"
Lasrick sends this report from Nature News: "The devastating 2011 earthquake and tsunami in Japan shocked researchers who did not expect that the seismic fault involved could release so much energy. Now the world's deepest-drilling oceanographic ship has been able to pin down the odd geology that made this disaster so horrific. The fault turns out to be unusually thin and weak, the researchers report in Science this week1–3. The results will help to pin down whether other offshore faults around the world are capable of triggering the same scale of disaster. ... The coring revealed a very thin clay layer, about 5 meters thick, separating the two sliding tectonic plates (abstract). 'That’s just weird,' says Emily Brodsky of the University of California, Santa Cruz (UCSC), who is an author on all three Science papers this week. 'Usually it’s tens of meters or more.' Lab tests confirmed that this wet clay layer is extremely slippery, and gets even more so under stress (abstract). As sliding creates friction and heat, water in the clay gets pressurized and pushes up against the impermeable rock around it. That 'jacks open the fault” says Brodsky, allowing it to slip even more. The temperature sensors found that more than a year after the quake, the fault was still up to 0.31 C warmer than its surroundings (abstract). From this they could extrapolate how much heat was generated from friction during the sliding event. Their calculations confirmed the very low friction of the 5-meter-thick clay layer."
theodp writes "Among the patents granted to Facebook this week by the USPTO is one for Inferring Household Income for Users of a Social Networking System. 'For example,' Facebook explains, 'an assumption might be made about a user that reads CNN.com and nytimes.com every day that the user is in a higher income bracket than another user that only reads TMZ.com and PerezHilton.com on the theory that a user who reads newspapers might be assumed to make more money than a user who only reads celebrity gossip blogs.' Advertisements such as those for travel packages, cars, and home mortgages, Facebook adds, 'are targeted to users based on income bracket,' which might also be inferred by 'gathering and analyzing different types of information about a user's geographic location.' Hey, what could go wrong?"
walterbyrd sends this news from Techworld: "A Microsoft storage patent that was used to get a sales ban on products from Google-owned Motorola Mobility in Germany has been invalidated by the German Federal Patent Court. Microsoft's FAT (File Allocation Table) patent, which concerns a 'common name space for long and short filenames' was invalidated on Thursday, a spokeswoman for the Federal Patent Court said in an email Friday. She could not give the exact reasons for the court's decision before the written judicial decision is released, which will take a few weeks."
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."
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."
