quax writes "Getting a scientific paper published that goes against the grain of conventional wisdom was never easy. Especially when it seems to contain an obvious glaring mistake. Fortunately despite already being some kind of pop celebrity with no shortage of fan mail, Einstein still opened letters he received from strangers. And this is how a trivial, fateful counting mistake was able to change the course of physics forever."

An anonymous reader writes "In a new feature on the future of high-frequency trading, Wired suggests that neutrino-powered financial trading systems may be coming soon, which would enable extremely low-latency information to be transmitted directly through the center of the Earth between major financial exchanges. If finance becomes the killer app for neutrino communication technology, it may ultimately make Neutrino SETI feasible. Quoting: 'It is only a matter of time, perhaps a few decades, says Alexander Wissner-Gross, a Harvard physicist, before some hedge fund decides it needs a particle accelerator to generate neutrinos, and then everyone will want one. Yes, they travel slower than light, but they indisputably can tunnel through the earth, cutting thousands of miles off an intercontinental message. And just a few days before the Battle of the Quants, right before the bad news about faster-than-light neutrinos, researchers announced they had sent a message by neutrino from the Fermilab accelerator in Chicago to a detector a kilometer away. According to Dan Stancil of North Carolina State University, the signal traveled at "very close to" the speed of light. Unfortunately, the data rate was only about 0.1 bits per second, meaning it would be useless for much more than sending a yes/no signal. "With the right modulation scheme, this could be increased by at least one or two orders of magnitude," Stancil said, adding "I don’t know of a compelling commercial application." But we’ve all heard the (apocryphal) story that Thomas J. Watson of IBM predicted "a world market for maybe five computers."'"

Hugh Pickens writes "Humans have pondered their mortality for millennia. Now the University of California at Riverside reports that it has received a $5 million grant from the John Templeton Foundation that will fund research on aspects of immortality, including near-death experiences and the impact of belief in an afterlife on human behavior. 'People have been thinking about immortality throughout history. We have a deep human need to figure out what happens to us after death,' says John Martin Fischer, the principal investigator of The Immortality Project. 'No one has taken a comprehensive and sustained look at immortality that brings together the science, theology and philosophy.' Fischer says he going to investigate two different kinds of immortality. One is the possibility of living forever without dying. The main questions there are whether it's technologically plausible or feasible for us, either by biological enhancement such as those described by Ray Kurzweil, or by some combination of biological enhancement and uploading our minds onto computers in the future. Second would be to investigate the full range of questions about Judeo, Christian, Hindu, Buddhist, and other Asian religions' conceptions of the afterlife to see if they're theologically and philosophically consistent. 'We'll look at near death experiences both in western cultures and throughout the world and really look at what they're all about and ask the question — do they indicate something about an afterlife or are they kind of just illusions that we're hardwired into?'"

An anonymous reader tips news of a study from researchers at the University of Strathclyde which found bilingual children to be significantly more successful at a set of tasks than children who spoke only one language. "The differences were linked to the mental alertness required to switch between languages, which could develop skills useful in other types of thinking." Lead researcher Fraser Lauchlan said, "Bilingualism is now largely seen as being beneficial to children but there remains a view that it can be confusing, and so potentially detrimental to them. Our study has found that it can have demonstrable benefits, not only in language but in arithmetic, problem solving and enabling children to think creatively. We also assessed the children's vocabulary, not so much for their knowledge of words as their understanding of them. Again, there was a marked difference in the level of detail and richness in description from the bilingual pupils."

ananyo writes "In a feature that recalls Asimov's Foundation series and 'psychohistory', Nature profiles mathematician Peter Turchin, who says he can see meaningful cycles in history. Worryingly, Turchin predicts a wave of violence in the United States in 2020. Quoting from the piece: 'To Peter Turchin, who studies population dynamics at the University of Connecticut in Storrs, the appearance of three peaks of political instability at roughly 50-year intervals is not a coincidence. For the past 15 years, Turchin has been taking the mathematical techniques that once allowed him to track predator-prey cycles in forest ecosystems, and applying them to human history. He has analyzed historical records on economic activity, demographic trends and outbursts of violence in the United States, and has come to the conclusion that a new wave of internal strife is already on its way. The peak should occur in about 2020, he says, and will probably be at least as high as the one in around 1970. 'I hope it won't be as bad as 1870,' he adds." We recently discussed similar research into predicting violence in the short term.

An anonymous reader writes "Researchers on the Square Kilometer Array project to build the world's largest radio telescope believe that a GPU cluster could be suited to stitching together the more than an exabyte of data that will be gathered by the telescope each day after its completion in 2024. One of the project heads said that graphics cards could be cut out for the job because of their high I/O and core count, adding that a conventional CPU-based supercomputer doesn't have the necessary I/O bandwidth to do the work."

New submitter susmit writes with news of India's new goal for launching a satellite to Mars in 2013. From the article: "India plans to launch a mission to Mars next year, putting an orbital probe around the red planet to study its climate and geology, top space department officials said on Thursday. ... A 320-tonne Indian Polar Satellite Launch Vehicle rocket will be used to carry the orbiter spaceship, blasting off from the ISRO launch site at Sriharikota in the southern state of Andhra Pradesh. Another senior official at ISRO, requesting anonymity, estimated the cost of the mission at 4.0-5.0 billion rupees ($70-90 million dollars)."

Krau Ming writes "After about eight years spent in research, I've made the decision to go back to school — medical school. When I last spent the bulk of my days sitting in lectures, I took notes with paper, and if the professor wasn't technologically impaired, he/she would have posted powerpoint slides as a PDF online for us to print and make our notes on. Since it has been so long, I am looking for some options other than the ol' pen and paper. Is there an effective way of taking notes with a laptop? What about tablet options? Are there note-taking programs that can handle a variety of file types (eg: electronic textbooks, powerpoint slides, PDFs)? Or should I just sleep in and get the lectures posted online and delay learning the course material until the exam (kidding)?"

Diggester tips news that physicists from Tsinghua University in China have published "the first proof-of-principle demonstration of a genuine quantum router." The group's paper (PDF) is available at the arXiv. MIT's Technology Review describes it thus: "In this new device, the information is encoded in the polarization of photons, either horizontal or vertical. The Chinese group begin by creating a single photon that is in a superposition of both horizontal and vertical polarization states. They then convert this single photon into a pair of lower energy photons that are entangled, a process called parametric down conversion. Both of these photons are also in a superposition of polarization states. The router works by using the polarization of one of these photons as the control signal to determine the route of the other, the data signal. The device is simple, little more than a collection of half mirrors for guiding photons and waveplates for rotating their polarization."

ananyo writes "Astronomers think they have seen the flare of a dying star being eviscerated by a black hole. The signal, spotted by three different satellites, could shed light on the relationship between the smaller black holes seen in our own galaxy and the supermassive ones in distant reaches of the Universe. The stellar victim was first seen in 2011 by Swift, a NASA satellite designed to spot bursts of high-energy photons known as gamma-rays. For more than a month, Swift watched a signal from a distant galaxy, which eventually faded from view. Subsequent analysis showed that the gamma-rays probably came from a star being ripped to pieces by a previously unknown black hole (abstract)."

coondoggie writes "NASA today continued its development of commercial space systems by splitting a little over $1.1 billion with Boeing, Space Exploration Technologies (Space X) and Sierra Nevada to develop and build advanced spaceships. 'Today's awards give a huge advantage to the three companies that got them, because competitors will need to fund their own development in its entirety. On the other hand, by partnering with the competitors, NASA has managed to seed the development of five different manned space vehicles for under $1B so far, a leap forward for the evolving space passenger market. They've paid for it on a reward-for-progress basis, handing out pre-agreed amounts of money for each specified milestone. SpaceX was well ahead of the other two competitors because of the unmanned Dragon, which has already berthed with the International Space Station. The company has borne the brunt of the development costs itself, putting in about $300 million of its own money in addition to about $75 million from NASA.'"

schliz writes "iTnews in Australia has published an interview with CERN's deputy head of IT, David Foster, who explains what last month's discovery of a 'particle consistent with the Higgs Boson' means for the organization's IT department, why it needs a second 'Tier Zero' data center, and how it is using grid computing and the cloud. Quoting: 'If you were to digitize all the information from a collision in a detector, it’s about a petabyte a second or a million gigabytes per second. There is a lot of filtering of the data that occurs within the 25 nanoseconds between each bunch crossing (of protons). Each experiment operates their own trigger farm – each consisting of several thousand machines – that conduct real-time electronics within the LHC. These trigger farms decide, for example, was this set of collisions interesting? Do I keep this data or not? The non-interesting event data is discarded, the interesting events go through a second filter or trigger farm of a few thousand more computers, also on-site at the experiment. [These computers] have a bit more time to do some initial reconstruction – looking at the data to decide if it’s interesting. Out of all of this comes a data stream of some few hundred megabytes to 1Gb per second that actually gets recorded in the CERN data center, the facility we call "Tier Zero."'"

sciencehabit writes "Don't feel inadequate. Even though your teeth are largely composed of a mineral softer than that found in sharks, new tests suggest that they're just as tough. In sharks, the material coating the teeth is largely composed of fluoroapatite, a fluoridated phosphate mineral that in its pure form is harder than the hydroxyapatite found in the enamel of human teeth. But by pressing tiny metallic pyramids into the surfaces of teeth from a shortfin mako shark and a tiger shark, researchers found that the enameloid coating on shark teeth is no harder than that of the enamel on a human wisdom tooth. The teeth are, in fact, of comparable hardness because their surfaces aren't pure mineral but instead are made of mineral crystals bound together with proteins so that the material doesn't shatter under a sudden impact."

MarkWhittington writes "During an interview with USA Today on the eve of the arrival of the Mars Rover Curiosity, NASA administrator Charles Bolden had some interesting thoughts on why a humans-to-Mars mission should be international and not American-led, how the world should react positively to the Chinese beating America back to the moon, and what he would do (or rather not do) if NASA were to have an 'unlimited' budget."

Bryan Killett is a physicist working on the Gravity Recovery And Climate Experiment (GRACE) for NASA's Jet Propulsion Laboratory. GRACE is a joint mission of NASA and the German Aerospace Center which collects satellite data to learn about Earth's changing gravity field, specifically the high frequency changes associated with ocean tides. As the high tide comes in, more water is present, so gravity in that location is temporarily strengthened. These changes are detected with GRACE and used to improve ocean tide models. Dr. Killett provides the open source (GPLv3) code used to process GRACE data on his home page. Bryan has agreed to take a break from measuring gravity fields and answer your questions about GRACE and the climate changes it has revealed. Feel free to ask as many as you like but please confine your questions to one per post.

ananyo writes "South Korea's oldest nuclear reactor is set to restart after a four-month closure, despite strong opposition from local residents and activists. The Kori-1 reactor in Busan was shut down on 13 March, after it was revealed that the reactor and its emergency generator had temporarily lost power during routine maintenance the month before, causing the coolant temperature to rise. The power failure did not cause an accident, but a report by the International Atomic Energy Agency in Vienna discovered that senior engineers from Korea Hydro and Nuclear Power, which runs the reactor, had neglected the safety problems for more than a month after the loss of power. In June, after a safety check, the IAEA gave the green light for Kori-1 to resume operation. Korea's Nuclear Safety and Security Commission (NSSC) approved the restart on 4 July, but activists and local residents remain strongly opposed to restarting the reactor. At first, the Korean Ministry of Knowledge Economy, which oversees energy policy, had said that the restart would be delayed to alleviate anxiety. But the government changed its mind as a result of a nationwide heatwave that has put a strain on the country's electricity supply in recent days."

First time accepted submitter erdos-bacon sandwich writes "Gender tests may be the most controversial obstacle the athletes face. The London Games tries a new approach based on testosterone. Of all the obstacles athletes have had to overcome to compete in the Olympics, perhaps the most controversial has been the gender test. Originally designed to prevent men from competing in women's events, it is based on the premise that competitors can be sorted into two categories via established scientific rules. But the biological boundaries of gender aren't always clear."

An anonymous reader writes "Joyce Ehrlinger from Florida State University has researched this very phenomenon, and has led her to present a paper called 'Polite But Not Honest: How an Absence of Negative Social Feedback Contributes to Overconfidence' at the American Psychological Association's annual conference in Orlando on Friday. Social norms, Ehrlinger says, are the reason that we are averse to giving negative feedback. Her research recreated everyday social situations in which we hold back from giving our own negative views."

New submitter Zex_Suik writes "Japanese physicists have used one of Maxwell's thought experiments and the ability to turn information into energy to extract more energy from an entangled system than should be possible according to the laws of thermodynamics (abstract). From the article: 'Imagine two boxes of particles with trap door between them. You want to use the trap door to guide the faster particles into one box and the slower particles into the other. In a classical experiment you would have to measure the particles in both boxes to do this experiment. But things are different if the particles in one box are entangled with the particles in the other. In that case, measurements on the particles in one box give you info about both sets of particles. In essence, you're getting information for nothing. And since you can convert that information into energy, there is clear advantage when entanglement plays a role. That's hugely significant. It means that the laws of thermodynamics depend not only on classical phenomenon and information but on quantum effects too.'"
