Milky Way Magnetic Fields Charted
eldavojohn writes "Using radio telescope data, scientists from around the world have plotted the Milky Way Galaxy's magnetic field in the form of Faraday Depth. From the article, 'For 150 years, scientists have measured cosmic magnetic field by observing the Faraday effect. They know that when polarized light passes though a magnetized medium, the plane of polarization turns. This concept is called Faraday rotation. The strength and direction of the magnetic field governs the amount of rotation that occurs. So scientists observe the rotation to investigate the magnetic fields' properties. Radio astronomers study the polarized light from distant radio source, passing through the Milky Way on the way to Earth, in order to measure our Galaxy's magnetic field. By measuring the polarization of the light sources at different frequencies, researchers can determine the amount of Faraday rotation.' In the future, radio telescope technologies like LOFAR, eVLA, ASKAP, MeerKAT and the SKA hope to provide enhanced Faraday rotation data so scientists can better understand turbulence in galactic gas and these galactic magnetic field structures."Read more of this story at Slashdot.

$100,000 Prize: Prove Quantum Computers Impossible
mikejuk writes "Quantum computing is currently a major area of research — but is this all a waste of effort? Now Scott Aaronson, a well-known MIT computer scientist, has offered a prize of $100,000 for any proof that quantum computers are impossible: 'I'm now offering a US$100,000 award for a demonstration, convincing to me, that scalable quantum computing is impossible in the physical world.' Notice the two important conditions — 'physical world' and 'scalable.' The proof doesn't have to rule out tiny 'toy' quantum computers, only those that could do any useful work."Read more of this story at Slashdot.

President By Day, High-Tech Headhunter By Night
theodp writes "The White House is following up on an offer made by President Barack Obama this week to help find a job for an unemployed semiconductor engineer in Texas. The offer was made during a live online town hall after the ex-TI engineer's wife questioned the government's policy concerning H-1B visa workers. Obama asked for EE Darin Wedel's resume and said he would 'forward it to some of these companies that are telling me they can't find enough engineers in this field.' While grateful, patent-holder Wedel said the president's view on the job prospects for engineers in his field 'is definitely not what's happening in the real world.' Duke adjunct professor Vivek Wadhwa offered his frank take on 40-year-old Wedel's predicament: 'The No. 1 issue in the tech world is as people get older, they generally become more expensive. So if you're an employer who can hire a worker fresh out of college who is making $60,000 versus an older worker who is making $150,000, and the younger worker has skills that are fresher, who would you hire?' Coincidentally, Texas Instruments sought President Obama's help in reducing restrictions on the hiring of younger foreign workers in 2009, the same year it laid off Wedel."Read more of this story at Slashdot.

You Will Never Kill Piracy
scottbomb writes "This is perhaps the best op-ed I've read about the whole SOPA/PIPA controversy. The author challenges Hollywood to re-think their entire business model. It will undoubtedly fall on deaf ears, for now. But sooner or later, they will have no choice but to adapt. From the article: 'Now that the SOPA and PIPA fights have died down, and Hollywood prepares their next salvo against internet freedom with ACTA and PCIP, it's worth pausing to consider how the war on piracy could actually be won. It can't, is the short answer, and one these companies do not want to hear as they put their fingers in their ears and start yelling.'"Read more of this story at Slashdot.

New Mobile Plan Pools Data On Unlimited Devices
Hugh Pickens writes "PC Magazine reports that Ting, a new reseller of Sprint's voice, 3G and WiMax services, has a new approach to mobile pricing that lets customers buy minutes, messages, and data separately, and allows households to pool them to an unlimited number of phones and data devices on one account. 'Household data plans are the next step for consumers, mainly because people are adding more connected screens and devices to their lifestyle,' writes Kevin Tofel. 'And different household members have different data needs; some use a little while others consume gobs of gigabytes. Why not average out the usage across multiple devices?' Both AT&T and Verizon have hinted at offering shared data plans in the future, but the devil's in the details, says Tofel. 'My hope is that family data plans come soon, to all carriers, just like we have for family voice and messaging plans.'"Read more of this story at Slashdot.

The Destruction of Iraq's Once-Great Universities
Harperdog writes "Hugh Gusterson has written a devastating article about what has happened to Iraq's once great university system, and puts most of the blame for its total collapse on the U.S. Quoting: 'While American troops guarded the Ministries of Oil and the Interior but ignored cultural heritage sites, looters ransacked the universities. For example, the entire library collections at the University of Baghdad's College of Arts and at the University of Basra were destroyed. The Washington Post's Rajiv Chandresekara described the scene at Mustansiriya University in 2003: "By April 12, the campus of yellow-brick buildings and grassy courtyards was stripped of its books, computers, lab equipment and desks. Even electrical wiring was pulled from the walls. What was not stolen was set ablaze, sending dark smoke billowing over the capital that day."'"Read more of this story at Slashdot.

World's Largest Virtual Optical Telescope Created
erice writes "Astronomers in Chile linked four telescopes together to form a single virtual mirror 130 meters in diameter. Previous efforts had linked two telescopes but this is the first time that all four had been linked. 'The process that links separate telescopes together is known as interferometry. In this mode, the VLT becomes the biggest ground-based optical telescope on earth. Besides creating a gigantic virtual mirror, interferometry also greatly improves the telescope's spatial resolution and zooming capabilities.'"Read more of this story at Slashdot.

Facebook On Collision Course With New EU Privacy Laws
An anonymous reader writes "Facebook and other U.S. internet companies are faced with a new EU data protection regime, the Christian Science Monitor reports. U.S. concepts of free expression and commerce will battle European support for privacy and state legislation. 'Companies must understand that if they want access to 500 million consumers in the EU, then they have to comply. This is not an option,' said a spokesman for the EU Justice Commissioner."Read more of this story at Slashdot.

Researchers Feel Pressure To Cite Superfluous Papers
ananyo writes "One in five academics in a variety of social science and business fields say they have been asked to pad their papers with superfluous references in order to get published. The figures, from a survey published in the journal Science (abstract), also suggest that journal editors strategically target junior faculty, who in turn were more willing to acquiesce. The controversial practice is not new: those studying publication ethics have for many years noted that some editors encourage extra references in order to boost a journal's impact factor (a measure of the average number of citations an article in the journal receives over two years). But the survey is the first to try to quantify what it calls 'coercive citation,' and shows that this is 'uncomfortably common.' Perhaps the most striking finding of the survey was that although 86% of the respondents said that coercion was inappropriate, and 81% thought it damaged a journal's prestige, 57% said they would add superfluous citations to a paper before submitting it to a journal known to coerce. However, figures from Thomson Reuters suggest that social-science journals tend to have more self-citations than basic-science journals."Read more of this story at Slashdot.

Ask Slashdot: Are Daily Stand-Up Meetings More Productive?
__roo writes "The Wall Street Journal reports that an increasing number of companies are replacing traditional meetings with daily stand-ups. The article points out that stand-up meetings date back to at least World War I, and that in some place, late employees 'sometimes must sing a song like "I'm a Little Teapot," do a lap around the office building or pay a small fine.' Do Slashdot readers feel that stand-up meetings are useful? Do they make a difference? Are they a gimmick?"Read more of this story at Slashdot.

Doctors 'Cheating' On Board Certifications
Maximum Prophet writes "After taking board exams, doctors have been routinely getting together to remember and reproduce as much of the exam as they can. These notes are then bound and reproduced. According to the American Board of Dermatology, the exams are protected by copyright laws, and any reproduction not approved by the board is illegal. While I have no doubt that the Board believes this, and pays lawyers to believe it as well, I don't think they understand copyright. Perhaps they should invest in better testing methods."Read more of this story at Slashdot.

Yes We Can (Profile You): a Brief Primer On Campaigns and Political Data
An anonymous reader writes "In the Stanford Law Review Online, Professor Daniel Kreiss discusses 'the history of political data, focusing on the recent proliferation in voter data and development of new voter-modeling techniques,' and how 'these data practices undermine privacy and democratic practice, even as they increase participation and voter turnout.' He writes: 'Underlying all of this is a vast data infrastructure that has made targeted online advertising and marketing possible, and has contributed to a revival of field campaigning over the last decade. Online advertising and field campaigning rely on voter modeling based on hundreds of data points culled from surveys, public records, and commercial information sources such as credit histories. This data details the location, demographics, political affiliations, social networks, behavior, and interests of citizens.'"Read more of this story at Slashdot.

Apple Clarifies iBooks Author Licensing
bonch writes "After drawing criticism over iBooks Author's licensing language, Apple has modified it in a software update to make clear that Apple is claiming rights to the .ibook format itself and not the content therein: '[The license restriction] does not apply to the content of such works when distributed in a form that does not include files in the .ibooks format.' In other words, the content may be sold on competing book stores as long as it is not packaged using iBooks Author."Read more of this story at Slashdot.

Satellite Phone Encryption Cracked
New submitter The Mister Purple writes "A team of German researchers appears to have cracked the GMR-1 and GMR-2 encryption algorithms used by many (though not all) satellite phones. Anyone fancy putting a cluster together for a listening party? 'Mr. Driessen told The Telegraph that the equipment and software needed to intercept and decrypt satellite phone calls from hundreds of thousands of users would cost as little as $2,000. His demonstration system takes up to half an hour to decipher a call, but a more powerful computer would allow eavesdropping in real time, he said.'"Read more of this story at Slashdot.
