assertation writes "A few weeks ago an article was posted to Slashdot referring to a Stanford Study stating that organic produce, contrary to popular belief is not more nutritious. According to Mark Bitman of The New York times the Stanford study was flawed. A spelling error skewed the results as well as the study ignoring several types of nutrients."

The Bad Astronomer writes "A century ago, astronomers (including Edwin Hubble) discovered the Universe was expanding. Using the same methods — but this time with observations from an orbiting infrared space telescope — a new study confirms this expansion, and nails the rate with higher precision than done before. If you're curious, the expansion rate found was 74.3 +/- 2.1 kilometers per second per megaparsec — almost precisely in line with previous measurements."
dsinc writes "A new study suggests caffeinated coffee drinkers should limit their intake to reduce their chances of developing vision loss or blindness. According to a scientific paper in Investigative Ophthalmology & Visual Science, heavy caffeinated coffee consumption is associated with an increased risk of developing exfoliation glaucoma (abstract), the leading cause of secondary glaucoma worldwide. 'Scandinavian populations have the highest frequencies of exfoliation syndrome and glaucoma,' said author Jae Hee Kang, ScD, of Channing Division of Network Medicine at Brigham and Women's Hospital in Boston, Mass. 'Because Scandinavian populations also have the highest consumption of caffeinated coffee in the world, and our research group has previously found that greater caffeinated coffee intake was associated with increased risk of primary open-angle glaucoma, we conducted this study to evaluate whether the risk of exfoliation glaucoma or glaucoma suspect may be different by coffee consumption.'"
Lucas123 writes "The problem: What do you leave behind that billions of years from now, and without context, would give aliens an some kind of accurate depiction of mankind. The answer: A gold-plated silicon disc with just 100 photos. That's the idea behind The Last Pictures project, which is scheduled to blast off in the next few months from Kazakhstan and orbit the earth for 5 billion years. The photos, etched into the silicon using a bitmap format, were chosen over a five-year process that involved interviews with artists, philosophers, and MIT scientists, who included biologists, physicists, and astronomers. To each, was posed a single question: What photos would you choose to send into outer space? The answer became an eclectic mix of images from pre-historic cave paintings to a photo of a group of people taken by a predator drone."
First time accepted submitter Walking The Walk writes "Your co-workers who keep using Schrödinger's cat metaphor may need to find a new one. New Scientist reports that 'by making constant but weak measurements of a quantum system, physicists have managed to probe a delicate quantum state without destroying it – the equivalent of taking a peek at Schrodinger's metaphorical cat without killing it. The result should make it easier to handle systems such as quantum computers that exploit the exotic properties of the quantum world.'"
RocketAcademy writes "ABC News is reporting that Phantom of the Opera singer/actress Sarah Brightman outbid NASA for a seat on a Soyuz flight to the International Space Station. Brightman reportedly paid more than $51 million. If that story is true, there may be some interesting bidding wars in the future."
New submitter CelestialScience writes "The heavens have aligned in a way never seen before, with two exoplanets overlapping as they cross their star. Teruyuki Hirano of the University of Tokyo, Japan, and colleagues used data from the Kepler space telescope to probe KOI-94, a star seemingly orbited by four planets. It seems that one planet candidate, KOI-94.03, passed in front of the star and then the innermost candidate, KOI-94.01, passed between the two. The phenomenon is so new it doesn't yet have a name, though suggestions include 'planet-planet eclipse,' 'double transit,' 'syzygy' and 'exosyzygy.'"
eldavojohn writes "A recent peer reviewed paper and survey by Cliff Frohlich of the University of Texas' Institute for Geophysics reveals a correlation between an increase in earthquakes and the emergence of fracking sites in the Barnett Shale, Texas. To clarify, it is not the actual act of hydrofracking that induces earthquakes, but more likely the final process of injecting wastewater into the site, according to Oliver Boyd, a USGS seismologist. Boyd said, 'Most, if not all, geophysicists expect induced earthquakes to be more likely from wastewater injection rather than hydrofracking. This is because the wastewater injection tends to occur at greater depth, where earthquakes are more likely to nucleate. I also agree [with Frohlich] that induced earthquakes are likely to persist for some time (months to years) after wastewater injection has ceased.' Frohlich added, 'Faults are everywhere. A lot of them are stuck, but if you pump water in there, it reduces friction and the fault slips a little. I can't prove that that's what happened, but it's a plausible explanation.' In the U.S. alone this correlation has been noted several times."
Shipud writes "Bioinformatics science which deals with the study of methods for storing, retrieving, and analyzing molecular biology data. Byte Size Biology writes about ROSALIND, a cool concept in learning bioinformatics, similar to Project Euler. You are given problems of increasing difficulty to solve. Start with nucleotide counting (trivial) and end with genome assembly (putting it mildly, not so trivial). To solve a problem, you download a sample data set, write your code and debug it. Once you think you are ready, you have a time limit to solve and provide an answer for the actual problem dataset. If you mess up, there is a timed new dataset to download. This thing is coder-addictive. Currently in Beta, but a lot of fun and seems stable."
scibri writes "A few months ago, the secretive National Reconnaissance Office gave NASA two Hubble-sized space telescopes that it didn't want anymore. Now the space agency has to figure out what to do with them, and whether it can afford it. The leading candidate to use one of the telescopes is the the proposed Wide-Field Infrared Space Telescope (WFIRST), which would search for the imprint of dark energy, find exoplanets and study star-forming regions of the Galaxy. The NRO telescope could speed up the mission, but may end up costing more in the long run." A few issues with re-purposing the NRO satellite: higher launch costs because it's bigger, it can't see as far or as much IR (but it can see fainter objects, and could be used in planet detection), and the need for a bigger camera.
ananyo writes "Bucking a trend of cutting science seen elsewhere, the French government has committed to increasing spending on research and development in its draft austerity budget for 2013. France's education and research ministry gets a 2.2% boost under the proposed budget, giving it a budget of just under €23 billion (US$29 billion). Most other ministries get a cut. The upshot of the cash increase is that 1,000 new university posts will be created, no publicly funded research jobs will be cut and funding for research grants will rise (albeit less than inflation) by 1.2% to €7.86 billion. The move to spend on science during a recession is notable and means that French politicians understand that a sustainable commitment to public spending on science is vital for long-term economic growth. The situation is in stark contrast to that in the U.S. and in the UK, where a recent policy to boost hi-tech industries, unveiled with much fanfare, failed to do much for science. Meanwhile, in Australia, there's alarm over proposals to freeze research grants— a step that could jeopardize 1700 jobs."
the_newsbeagle writes "To study the mysterious phenomena of dark matter and dark energy, astronomers are turning to supercomputers that can simulate the entire evolution of the universe. One such simulation, the Bolshoi projection, recently did a complete run-through. It started with the state the universe was in around 13.7 billion years ago (not long after the Big Bang) and modeled the evolution of dark matter and energy up to the present day. The run used 14,000 CPUs on NASA's fastest supercomputer."
SchrodingerZ writes "With the price of gold skyrocketing in today's market, Michigan State University researchers have discovered a bacterium that can withstand high toxicity levels that are necessary to create natural gold. '"Microbial alchemy is what we're doing — transforming gold from something that has no value into a solid, precious metal that's valuable," said Kazem Kashefi, assistant professor of microbiology and molecular genetics.' The bacteria is Cupriavidus metallidurans, which is conditioned to be tolerant to heavy, toxic metals and to be 25 times stronger than most bacteria. When put into gold-chloride (a natural forming toxic liquid), the bacteria reproduces and converts the liquid into a gold nugget. The complete process takes about a week to perform. This experiment is currently on tour as an art exhibit called 'The Great Work of the Metal Lover.'"
Lasrick writes "Private security contractors strike again, this time at the Y-12 National Security Complex. A nun, a gardener, and a housepainter cut through three security fences to find themselves 20 feet away from highly dangerous nuclear material. And of course, only one guard has been fired (the one who arguably acted the bravest and did the right thing). A Department of Energy report (PDF) on the incident found 'troubling displays of ineptitude in responding to alarms, failures to maintain critical 2 security equipment, over reliance on compensatory measures, misunderstanding of security protocols, poor communications, and weaknesses in contract and resource management.' The contractors have been put on notice, (PDF), but they still have the contracts."
ananyo writes "One of the largest-ever studies of retractions has found that two-thirds of retracted life-sciences papers were stricken from the scientific record because of misconduct such as fraud or suspected fraud — and that journals sometimes soft-pedal the reason. The study contradicts the conventional view that most retractions of papers in scientific journals are triggered by unintentional errors. The survey examined all 2,047 articles in the PubMed database that had been marked as retracted by 3 May this year. But rather than taking journals' retraction notices at face value, as previous analyses have done, the study used secondary sources to pin down the reasons for retraction if the notices were incomplete or vague. The analysis revealed that fraud or suspected fraud was responsible for 43% of the retractions. Other types of misconduct — duplicate publication and plagiarism — accounted for 14% and 10% of retractions, respectively. Only 21% of the papers were retracted because of error (abstract)."
concealment writes "How much privacy is the scientific process entitled to? During the course of their work, researchers produce e-mails, preliminary results, and peer reviews, all of which might be more confused or critical than the final published works. Recently, both private companies with a vested interest in discounting the results, and private groups with a political axe to grind have attempted to use the courts to get access to that material.Would it be possible or wise to keep these documents private and immune to subpoenas? In the latest issue of Science, a group of researchers from the Woods Hole Oceanographic Institution (WHOI) argue that scientists need more legal rights to retain these documents and protect themselves in court."
black6host writes "Humans have reached the moon and are planning to return samples from Mars, but when it comes to exploring the land deep beneath our feet, we have only scratched the surface of our planet. This may be about to change with a $1 billion mission to drill 6 km (3.7 miles) beneath the seafloor to reach the Earth's mantle — a 3000 km-thick layer of slowly deforming rock between the crust and the core which makes up the majority of our planet — and bring back the first ever fresh samples."
An anonymous reader writes "British researchers at the Universities of Sussex and Sheffield are developing a computer model of a bee's brain that they hope can help scientists better understand the brains of more-complex animals, such as humans, and perhaps power artificial intelligence systems for bee-like robots. Called 'Green Brain,' the project is trying to advance the science of AI beyond systems that just follow a predetermined set of rules, and into an area where AI systems can actually act autonomously and respond to sensory signals."
RougeFive writes "Imagine a warship weapon that can launch projectiles at Mach 10 without explosives (more than three times the muzzle speed of an M16 rifle), that has a range of 220 miles and that uses the enormous speed to destroy the target by causing as much damage as a Tomahawk missile. Meet the U.S. Navy's electromagnetic railgun program."
