The Galaxy S IV ? or Galaxy S4, if you prefer ? is being watched very carefully in the tech world, and or good reason: Its predecessor, the Galaxy S III, has been one of the only phones in recent memory to really challenge the supremacy of the Apple iPhone. Not only did the Galaxy S III beat out the iPhone 5 in CNET's annual list of best tech products of 2012, but it also beat out the iPhone 5 on the sales charts in the third quarter of 2012 ? no mean feat.

With the launch of the Galaxy S IV, Samsung could be looking at the solidification of a real dynasty.?

And today, we got an intriguing peek at the features on the forthcoming device, courtesy of the New York Times. According to Times reporter Brian X. Chen, the Galaxy S IV may include a feature that tracks the motion of our eyeballs, and readjusts the text correspondingly. "For example," Chen writes, "when users read articles and their eyes reach the bottom of the page, the software will automatically scroll down to reveal the next paragraphs of text."

Samsung has applied for a patent on "eye scroll" technology, although the company has declined to say whether or not the feature will be included on the S IV.?Still, this is some pretty cool stuff ? closer to science fiction technology than anything on the market today. We're looking forward to hearing more.?

In related news, the next Samsung phone is expected to have a big screen ? possibly as large as 4.99-inches measured corner from corner. That would put the display at almost a full inch larger than the display on the iPhone 5. Meanwhile, as PC Magazine notes, the Galaxy S IV may take advantage of the new?Exynos 5 Octa 8-core processor, which was unveiled at CES back in 2013.?

The Galaxy S IV will be officially introduced at a media event on March 14. The unveiling will be held in?New York, but it will be live-streamed via YouTube.?

Man-made material pushes the bounds of superconductivity

Monday, March 4, 2013

A multi-university team of researchers has artificially engineered a unique multilayer material that could lead to breakthroughs in both superconductivity research and in real-world applications.

The researchers can tailor the material, which seamlessly alternates between metal and oxide layers, to achieve extraordinary superconducting properties ? in particular, the ability to transport much more electrical current than non-engineered materials.

The team includes experts from the University of Wisconsin-Madison, Florida State University and the University of Michigan. Led by Chang-Beom Eom, the Harvey D. Spangler Distinguished Professor of materials science and engineering and physics at UW-Madison, the group described its breakthrough March 3, 2013, in the advance online edition of the journal Nature Materials.

Superconductors, which presently operate only under extremely cold conditions, transport energy very efficiently. With the ability to transport large electrical currents and produce high magnetic fields, they power such existing technologies as magnetic resonance imaging and Maglev trains, among others. They hold great potential for emerging applications in electronic devices, transportation, and power transmission, generation and storage.

Carefully layered superconducting materials are increasingly important in highly sophisticated applications. For example, a superconducting quantum interference device, or SQUID, used to measure subtle magnetic fields in magnetoencephalography scans of the brain, is based on a three-layer material.

However, one challenge in the quest to understand and leverage superconductivity is developing materials that work at room temperature. Currently, even unconventional high-temperature superconductors operate below -369 degrees Fahrenheit.

An unconventional high-temperature superconductor, the researchers' iron-based "pnictide" material is promising in part because its effective operating temperature is higher than that of conventional superconducting materials such as niobium, lead or mercury.

The research team engineered and measured the properties of superlattices of pnictide superconductors. A superlattice is the complex, regularly repeating geometric arrangement of atoms ? its crystal structure ? in layers of two or more materials. Pnictide superconductors include compounds made from any of five elements in the nitrogen family of the periodic table.

The researchers' new material is composed of 24 layers that alternate between the pnictide superconductor and a layer of the oxide strontium titanate. Creating such systems is difficult, especially when the arrangement of atoms, and chemical compatibility, of each material is very different.

Yet, layer after layer, the researchers maintained an atomically sharp interface ? the region where materials meet. Each atom in each layer is precisely placed, spaced and arranged in a regularly repeating crystal structure.

The new material also has improved current-carrying capabilities. As they grew the superlattice, the researchers also added a tiny bit of oxygen to intentionally insert defects every few nanometers in the material. These defects act as pinning centers to immobilize tiny magnetic vortices that, as they grow in strength in large magnetic fields, can limit current flow through the superconductor. "If the vortices move around freely, the energy dissipates, and the superconductor is no longer lossless," says Eom. "We have engineered both vertical and planar pinning centers, because vortices created by magnetic fields can be in many different orientations."

Eom sees possibilities for researchers to expand upon his team's success in engineering man-made superconducting structures. "There's a need to engineer superlattices for understanding fundamental superconductivity, for potential use in high-field and electronic devices, and to achieve extraordinary properties in the system," says Eom. "And, there is indication that interfaces can be a new area of discovery in high-temperature superconductors. This material offers those possibilities."

Copyright alerts won't go to coffee shops' Wi-Fi

Suzanne Choney , NBC News ? ? ? 3 hrs.

A new copyright alert system should not affect open Wi-Fi connections, like those at coffee shops, although not everyone is in agreement about that.

The new system, which kicked in last week, is being used by five major Internet service providers in the U.S. to target users who illegally share music, movies or TV shows online. Those users will get up to six warnings before action is taken, including possibly slowing down their Internet service.

The Center for Copyright Infringement, which is rolling out the system, "claims that the Copyright Alert System won't harm open wireless, but based on Internet service providers' recent announcements, it looks like this is far from true," Adi Kamdar of the Electronic Frontier Foundation, told NBC News.

"The program includes locking down one's open wireless network as a thorough way of preventing copyright infringement. We don't think the interests of the content industry should trump good Internet practices and policy."

The Center for Copyright Infringement, whose members include Recording Industry Association of America (RIAA) and Motion Picture Association of America (MPAA), as well as ISPs AT&T, Cablevision, Comcast, Time Warner Cable, and Verizon, sees the alert system as an education effort aimed at home users. (NBC News is part of NBCUniversal, which is owned by Comcast, a provider of cable TV and broadband Internet access.)

Jill Lesser, executive director of the CCI, has written in a blog post that residential Internet accounts "are the focus of our program. The vast majority of businesses, including those like Starbucks that provide legitimate open Wi-Fi connections, will have an Internet connection that is tailored to a business operation and these business networks are not part of the CAS and will never be sent a copyright alert."

The "six strikes" plan, as some dub it, is still rolling out, and each ISP will handle those "strikes" differently.

If you're a Verizon customer, for example,it works like this, a spokesman told NBC News: The first time illegal file-sharing is detected, the user will get an alert via email first. The second time, there will be both an email and a voice message. The third, a popup will appear on your computer screen, where the user must acknowledge receipt of the message. The fifth time, you'll be asked to watch a video about piracy and to say that you understand the issue.

The sixth warning brings you a notification that there will be a temporary slowdown in your Internet speed, although it won't be automatic, the Verizon spokesman said. If you're working on a huge term paper, for example, or trying to get a business plan finished up, and need that super-fast Internet for the next 48 hours, you'll work out a time for that slower service with Verizon.

Livestrong Made A New Logo - Business Insider

In an attempt to further separate itself from its infamous founder Lance Armstrong, Livestrong unveiled a subtle new logo that will hopefully rally consumers away from the doping scandal.

The old logo looked like this:

But it often came with the subtitle, "The Lance Armstrong Foundation."

But last week, EVP of operations Andy Miller revealed the new logo that emphasizes that Livestrong is a cancer fighting foundation rather than an extension of the disgraced cyclist.

Miller noted, "The change is subtle, but it is substantive. The positioning of the bars suggests forward and dynamic movement."

Armstrong officially cut all ties with his cancer-fighting organization in November to try to diminish the blow to the charity from his drugs scandal.

Livestrong itself has also tried to separate its association with Armstrong to avoid fallout, issuing a statement in January (following the famous Oprah interview) that it was "disappointed" in Armstrong but still "grateful" for his charitable?work.

Do you think that the new logo helps create a new image for the brand, or is it too subtle?

Why gas prices go up in the spring

Gas prices always seem to 'spring forward' in the spring. Here's what's behind the seasonal rise in gas prices.

By Robert Rapier,?Guest blogger / March 2, 2013

A gas station displays a price of $4.59 for a gallon of self-service regular gas in San Diego last month. Gas prices have spiked between 57 and 59 cents over the past 30 days in California.

Gasoline prices have been climbing rapidly of late, and it is happening earlier than normal. But why does it happen at all in the spring? There is no question that it does happen. If you check the history of gasoline prices at the US Energy Information Administration's (EIA) website you can see that gasoline prices almost always rise between January and May. For example, in 2011 the price rose by 90 cents a gallon between January and May. Last year, the price increase was 65 cents a gallon.

Many factors influence gasoline prices, but there are specific reasons behind the seasonal changes.

Two critical specifications that need to be met for each gasoline blend are the octane rating and the Reid vapor pressure (RVP). Octane rating is important for avoiding engine knocking. But the octane rating for a gasoline blend is consistent throughout the year, and is not the reason for the seasonal price fluctuations.

The RVP spec, however, does change with the seasons and this change can have a major effect on the price of fuel. The RVP is based on a test that measures vapor pressure of the gasoline blend at 100 degrees F.

Free Access to Law ? Is It Here to Stay? Research Publications of ...

?What is a Legal Information Institute when the transcripts of judgments are refused for publication ? even by the courts themselves ? by the company contracted to provide the transcription service on some very shady grounds of copyright?? That is one of the questions lingering in the wake of a very ambitious recent Free Access to Law project.

The mission of the Legal Information Institutes (LIIs) it to maximize free access to public legal information such as legislation and case law from as many countries and international institutions as possible. To that end they produced the publications linked above. The ?Local Researcher?s Methodology Guide? explains the reasons for the ?Free Access to Law ? Is It Here to Stay?? project in detail, and then provides instructions for researchers, including an ?environmental scan matrix? and associative questionnaires.

The ?Environmental Scan? is the first component of the ?Free Access to Law ? Is it Here to Stay?? global study on the sustainability of Free Access to Law initiatives. This report looks at the situation for the free open distribution of legal information in Kenya, Uganda, Hong Kong, India, Indonesia, Philippines, and Canada. The collected information includes a brief overview of each legal system, the legal environment (with a focus on copyright law, privacy, and secrecy based restrictions), legal education, the legal research environment (both online and off) and situates it in the context of each national economy.

The ?Good Practices Handbook? adds depth and clarity to the instructions set out in the ?Local Researchers Methodology Guide.? All three reflect the output of an undertaking that Mariya Badeva-Bright describes as an effort to ?link two central concepts ? the concept of success of a free access to law project and the concept of sustainability?. The objective is that by making law freely available, a legal information institute (LII) produces outcomes that benefit its target audience, thereby creating incentives among the target audience or other stakeholders to sustain the LII?s ongoing operations and development.?

The written portions of this project reflect an extensive and very thoughtful effort to map out ways that people can work toward consistent archiving and dissemination of legal information so that citizens have access to their own laws. As Kerry Anderson has noted In a VOXPOULII blog post, Free Access to Law matters the most to the poorest and most unstable communities:

Zimbabwe has not been able to publish its Law Reports since 2003 owing to the devastating collapse of infrastructure resulting from the political situation. Swaziland last published Law Reports in the 1980s. Many other countries have out-of-date Law Reports with no resources to continue the Law Reporting function. Others have written more eloquently than I on the necessity of having contextual law, particularly in common law jurisdictions. The point is singular and self-evident: how can the laws of a country be known if the laws of the country are not available?

Some of the project?s lessons are that ?digitization of print materials and/or manual capturing of metadata ? cannot be deemed a successful strategy in the long run ? it is simply uneconomical to continue to do so past a certain stage. Engaging stakeholders in education of use of technology or development of IT solutions to support workflows for delivering of judgments or passing legislation may be a way of dealing with issues of digitizing and automating delivering of law to the public. Standards of preparation of legal material ? adopted by all originators of legal information in a particular jurisdiction, will ease its dissemination and re-use.? In other words, dead trees are not nearly as helpful as electrons, even in very poor countries, in providing access to law. Part of me wants to resist this conclusion even though I concede that it is undoubtedly correct. Paper publications may be traditional, resilient, and fairly copyright-restriction-defying once they are published but they add a cumbersome step to any knowledge-distribution chain. And as we learn from these publications, money for Free Access to Law initiatives is scarce.

It may be, as Eve Gray concluded that ?[t]he most promising and sustainable future looks to be in small and innovative digital companies using open source publishing models, offering free content as well as value-added services for sale.? But librarians are a hardy and relentless people, and if there is a way to bring a Legal Information Institute to every corner of the globe, these are the people who will figure it out.
