An anonymous reader writes "In a real life Prisoner's Dilemma taking place in the French city of Marseille, twin brothers have been arrested for a string of sexual assaults. While say they are sure that one of them committed the crimes (corroborated by a standard DNA test), police were told that it would cost upwards of €1m euros (£850,000, $1.3m USD) to distinguish between them using DNA evidence."

gbrumfiel writes "A meteor that exploded over Russia's Chelyabinsk region this morning was the largest recorded object to strike the earth in more than a century, Nature reports. Infrasound data collected by a network designed to watch for nuclear weapons testing suggests that today's blast released hundreds of kilotons of energy. That would make it far more powerful than the nuclear weapon tested by North Korea just days ago, and the largest rock to strike the earth since a meteor broke up over Siberia's Tunguska river in 1908. Despite its incredible power, the rock evaded detection by astronomers. Estimates show it was likely only 15 meters across — too small to be seen by networks searching for near earth asteroids." Today's meteor event came a day after California scientists proposed a system to vaporize asteroids that threaten Earth. Of course, the process needs to be started when the asteroid is still tens of millions of kilometers away; there's no chance to shoot down something that's already arrived.
New submitter dmfinn writes "While his union address covered a wide range of topics, President Obama made sure not to skip over the U.S.'s space program. The talking point was nearly identical to the one he gave in 2009, in which he called for space R&D spending to be increased past the levels seen during the the original cold war space race. Now, 4 years after that speech, it appears things have gone the opposite way. Since 2009 NASA has seen some serious cuts. Not only has the space-shuttle program been deactivated, but the agency was forced to endure harsh funding cuts during the presidents latter term. Despite an ominous history, it now seems that Obama is back on the space objective, pushing congress to increase non-defensive R&D spending to 3% of the U.S. GDP. It's important to keep in mind that not all of this money goes directly to space related programs, though under the proposed budget the National Science Foundation, Department of Energy Office of Science, and the National Institute of Standards and Technology Laboratories will have their budgets doubled. There will also be an increase in tax credits towards companies and organizations working on these R&D projects. Should the U.S. go back to its 'Let's put a man on the moon' ideology, or is the federal government fighting an uphill battle against newly emerging private space expeditions? Either way, the question remains whether or not Obama will act on any of the propositions."
Hugh Pickens writes "Ariel Schwartz reports that researchers are working on an alcoholism vaccine that makes alcohol intolerable to anyone who drinks it. The vaccine builds on what happens naturally in certain people — about 20% of the Japanese, Chinese, and Korean population — with an alcohol intolerance mutation. Normally, the liver breaks down alcohol into an enzyme that's transformed into the compound acetaldehyde (responsible for that nasty hangover feeling), which in turn is degraded into another enzyme. The acetaldehyde doesn't usually have time to build up before it's broken down. But people with the alcohol intolerance mutation lack the ability to produce that second enzyme; acetaldehyde accumulates, and they feel terrible. Dr. Juan Asenjo and his colleagues have come up with a way to stop the synthesis of that second enzyme via a vaccine, mimicking the mutation that sometimes happens naturally. 'People have this mutation all over the world. It's like how some people can't drink milk,' says Asenjo. Addressing the physiological part of alcohol addiction is just one piece of the battle. Addictive tendencies could very well manifest in other ways; instead of alcohol, perhaps former addicts will move on to cigarettes. Asenjo admits as much: 'Addiction is a psychological disease, a social disease. Obviously this is only the biological part of it.'"
Today at about 19:25 UTC (2:25 PM EST), Asteroid 2012 DA14 will make its closest approach to Earth, passing a mere 27,650 kilometers above the surface — closer than our satellites in geosynchronous orbit. NASA is broadcasting a live-steam showing the asteroid from an Observatory, and will have coverage on NASA TV starting about a half-hour before closest approach. The Planetary Society will be broadcasting a live webcast, and Phil Plait will be hosting a Google+ Hangout. NASA has also compiled a nice post filled with information about the asteroid, including trajectory diagrams, animated videos of the path, and answers to question about 2012 DA14. You can also watch it move at 50x actual speed through a telescope. They take pains to note that there is no danger of the asteroid striking the planet today, or any time in the forseeable future. Its next notably close approach in 2046 will only bring it about a million kilometers away. What makes 2012 DA14 significant is that it's rather large — it's 45 meters across and weighs about 130,000 metric tons. It's also moving about 7.8 kilometers per second relative to Earth. "To view the asteroid, you will need a good pair of binoculars, or even better, a moderately powered telescope. During the closest approach, and dependant on local weather, the asteroid will be visible from parts of Europe, Africa and Asia. The asteroid will appear to be moving relatively quickly as it crosses the sky from the south to the north." NASA says this morning's meteor event in Russia was unrelated.
New submitter dovf writes "The Bad Astronomer analyzes incoming reports about the apparent meteoric fireball over Russia: 'Apparently, at about 09:30 local time, a very big meteor burned up over Chelyabinsk, a city in Russia just east of the Ural mountains, and about 1500 kilometers east of Moscow. The fireball was incredibly bright, rivaling the Sun! There was a pretty big sonic boom from the fireball, which set off car alarms and shattered windows. I'm seeing some reports of many people injured (by shattered glass blown out by the shock wave). I'm also seeing reports that some pieces have fallen to the ground, but again as I write this those are unconfirmed." This is the best summary I've found so far, and links to lots of videos and images. He also clarifies something I've been wondering about: 'This is almost certainly unrelated to the asteroid 2012 DA14 that will pass on Friday.'"
Bulldust writes "The Federal Court in Australia has ruled in favor of U.S. biotechnology company Myriad Genetics, enabling them to continue to hold the patent over the so-called breast cancer gene BRCA1. The same patent is also being reconsidered by the U.S. Supreme Court in the current session. From the article: 'Federal court Justice John Nicholas has ruled that a private company can continue to hold a patent over the so-called breast cancer gene BRCA1, in a decision that has devastated cancer victims.The decision is the first in Australia to rule on whether isolated genes can be patented, and will set a precedent in favor of commercial ownership of genetic material.'"
sciencehabit writes "Think potty training a child is hard? Try teaching a cow when and where to do its business. The bovines can defecate nine to 16 times daily, creating big hygiene problems on dairy and beef farms. So cueing the animals to go in the right place would be a big help for managing manure. But past techniques—including training cows to respond to mild electric shocks—have proven ineffective or impractical for wide use. To see if they could come up with a better potty prompt, scientists tested a series of stimuli on a dozen Holstein cows. The milkers stood in or walked through a footbath filled with water, for example, or had air or water sprayed on their feet. Alas, '[n]one of our tests reliably stimulated defecation,' the team reports."
coondoggie writes "The U.S. Food and Drug Administration today approved what it says is the first bionic eye, or retinal prosthesis, that can partially restore the sight of blind individuals after surgical implantation. The Argus II Retinal Prosthesis System includes a small video camera, transmitter mounted on a pair of eyeglasses, video processing unit (VPU) and an implanted artificial retina. The VPU transforms images from the video camera into electronic data that is wirelessly transmitted to the retinal prosthesis."
First time accepted submitter jscheib writes "According to Will Oremus in Slate, a report released today finds that 'New York City could slash its emissions by a whopping 90 percent by 2050 without any radical new technologies, without cutting back on creature comforts, and maybe even without breaking its budget.' The key elements are insulating buildings to cut energy needs, converting to (mostly) electric equipment, and then using carbon-free electricity to supply the small amount of energy still needed. Oremus notes that including energy savings would reduce the net price tag to something more like $20 billion."
puddingebola writes "Researchers have given lab rats the ability to sense infrared light through a brain implant. From the article, 'They taught the rats to choose the active light source by poking their noses into a port to receive a sip of water as a reward. They then implanted the microelectrodes, each about a tenth the diameter of a human hair, into the animals' brains. These electrodes were attached to the infrared detectors. The scientists then returned the animals to the test chamber. At first, the rats scratched at their faces, indicating that they were interpreting the lights as touch. But after a month, the animals learned to associate the signal in their brains with the infrared source.'"
An anonymous reader writes "Excitement and the media surrounded the Higgs boson particle for weeks when it was discovered in part by the Large Hadron Collider (LHC). But now, the collider that makes its home with CERN, the famed international organizational that operates the world's largest particle physics laboratory, is powering down. The Higgs boson particle was first discovered by the LHC in 2012. The particle, essentially, interacts with everything that has mass as the objects interact with the all-powerful Higgs field, a concept which, in theory, occupies the entire universe." We covered the repair announcement last month.
rogue-girl writes "Artist Heather Dewey-Hagborg showcases portrait sculptures from genetic material collected in public spaces. DNA extraction and processing are done in a DIYbio-compliant fashion at the DIYbio hackerspace Genspace in Brooklyn, the collected information is then given as input to a 3D printer. The software developed and used for this project is awkwardly dubbed 'friendware', that is it is neither open nor closed, but only available to friends. Reconstructing faces from DNA is not new: scientists already successfully reconstructed Neanderthal man's face from ancient DNA back in 2008. At first sight, the artist's project may seem fun and quite impressive as high-voltage science proves once more feasible at home, but all the data one can have access to from totally banal samples leaves open worrying perspectives about how easy it is to use DNA collected in public spaces for "fingerprinting" people against their will and without their consent."
ananyo writes "When influenza hit early and hard in the United States this year, it quietly claimed an unacknowledged victim: one of the cutting-edge techniques being used to monitor the outbreak. A comparison with traditional surveillance data showed that Google Flu Trends, which estimates prevalence from flu-related Internet searches, had drastically overestimated peak flu levels. The glitch is no more than a temporary setback for a promising strategy, experts say, and Google is sure to refine its algorithms. But with flu-tracking techniques based on mining of web data and on social media taking off, Nature looks at how these potentially cheaper, faster methods measure up against traditional epidemiological surveillance networks." Crowdsourcing is often useful, but it seems to have limits.
You may think that moshing and disordered 2D gases don't have much in common but Jesse Silverberg of Cornell University contends otherwise. He says that mosh pits act just like disordered gases and people in circle pits act in an ordered vortex-like state. From the article: "Silverberg and co gathered their data by examining videos of mosh pits on You Tube... These crowds contain anything from 100 to 100,000 people. After correcting for camera shake and distortions in perspective, they used particle image velicometry techniques to measure the collective motion of moshers. What they discovered was that the speed distribution of moshers closely matches that of molecules in a 2D gas at equilibrium."
judgecorp writes "Britain is considering switching off air traffic control radar systems and using "passive radar" instead. A two year feasibility study will consider using a network of ground stations which monitor broadcast TV signals and measure echoes from aircraft to determine their location and velocity. The system is not a new idea — early radar experiments used BBC shortwave transmitters as a signal source before antenna technology produced a transceiver suitable for radar — but could now be better than conventional radar thanks to new antenna designs and signal processing techniques. It will also save money and energy by eliminating transmitters — and release spectrum for 5G services."
An anonymous reader writes "Seed giant Monsanto has won more than $23 million from hundreds of small farmers accused of replanting the company's genetically engineered seeds. Now, another case is looming – and it could set a landmark precedent for the future of seed ownership. From the article: 'According to the report, Monsanto has alleged seed patent infringement in 144 lawsuits against 410 farmers and 56 small farm businesses in at least 27 U.S. states as of January of 2013. Monsanto, DuPont and Syngenta together hold 53 percent of the global commercial seed market, which the report says has led to price increases for seeds -- between 1995 and 2011, the average cost of planting one acre of soybeans rose 325 percent and corn seed prices went up 259 percent.'"
MTorrice writes "During the 2010 Deepwater Horizon oil spill in the Gulf of Mexico, clean up crews applied millions of liters of dispersants to break up the oil. At the time, the public and some scientists worried about the environmental effects of the chemicals, in particular how long they would last in the deep sea. According to a new Environmental Protection Agency study, the key active ingredient in the dispersants degrades very rapidly under conditions similar to those found at the Gulf surface during the spill. Meanwhile, in the much colder temperatures found in the deep sea, the breakdown is quite slow. The chemicals' persistence at deep-sea and Arctic temperatures suggests more research is needed on their toxicity, the researchers say."
ananyo writes "Synthetic biologists have developed DNA modules that perform logic operations in bacteria. These 'genetic circuits' could, for example, be used by scientists to track key moments in a cell's life or, in biotechnology, to turn on production of a drug at the flick of a chemical switch. The researchers have encoded 16 logic gates in modules of DNA and stored the results of logical operations. The different logic gates can be assembled into a wide variety of circuits."
Lucas123 writes "Applying the same technology used for voice recognition and credit card fraud detection to medical treatments could cut healthcare costs and improve patient outcomes by almost 50%, according to new research. Scientists at Indiana University found that using patient data with machine-learning algorithms can drastically improve both the cost and quality of healthcare through simulation modeling.The artificial intelligence models used for diagnosing and treating patients obtained a 30% to 35% increase in positive patient outcomes, the research found. This is not the first time AI has been used to diagnose and suggest treatments. Last year, IBM announced that its Watson supercomputer would be used in evaluating evidence-based cancer treatment options for physicians, driving the decision-making process down to a matter of seconds."
astroengine writes "During the flyby of asteroid 2012 DA14 on Friday, radio astronomers will be priming their antennae to do some cutting-edge science on the interplanetary interloper. After firing radio waves at the space rock, the Karl G. Jansky Very Large Array (VLA) will work in tandem with several dishes that make up the Very Long Baseline Array (VLBA) to detect the reflected signal, radar gun style. But they're not measuring the object's speed. They're actually going to gain a measure of DA14's spin, a quantity that relates to the physical mechanism of the Yarkovsky Effect — the impact that solar heating has on the long-term trajectory of asteroids."
Beeftopia writes "The relationship between regulator and regulated is once again called into question as industry pressure leads to a scientist's removal from an EPA regulatory panel. From the article: 'In 2007, when Deborah Rice was appointed chair of an Environmental Protection Agency panel assessing the safety levels of flame retardants, she arrived as a respected Maine toxicologist with no ties to industry. Yet the EPA removed Rice from the panel after an intense push by the American Chemistry Council (ACC), an industry lobbying group that accused her of bias. Her supposed conflict of interest? She had publicly raised questions about the safety of a flame retardant under EPA review.'"
dstates writes with news from NASA about the state of available water in the Middle East. From the NASA article: "'GRACE data show an alarming rate of decrease in total water storage in the Tigris and Euphrates river basins, which currently have the second fastest rate of groundwater storage loss on Earth, after India,' said Jay Famiglietti, principal investigator of the study and a hydrologist and professor at UC Irvine. 'The rate was especially striking after the 2007 drought. Meanwhile, demand for freshwater continues to rise, and the region does not coordinate its water management because of different interpretations of international laws.'" dstates adds: "Water is a huge global security issue. To understand the middle east, you need to understand that the Golan Heights provides a significant amount of the water used in Israel. Focusing on conflicts and politics means that huge volumes of valuable water are being wasted in the Middle East, and this will only exacerbate future conflicts. Water is a serious issue between India and China. And then there is Africa. U.S. food exports are in effect exporting irrigation water drawn from the Ogallala aquifer. Fracking trades water for energy, and lack of water limits fracking in many parts of th world. Think about it."

Mirk writes "Academic researchers want to make their papers open access for the world to read. If they use traditional publishers like Elsevier, Springer or Taylor & Francis, they'll be charged $3000 to bring their work out from behind the paywall. But PeerJ, a new megajournal launched today and funded by Tim O'Reilly, publishes open access articles for $99. That's not done by cutting corners: the editorial process is thorough, and they use rigorous peer-review. The cost savings come from running lean and mean on a born-digital system. The initial batch of 30 papers includes one on a Penn and Teller trick and one on the long necks of dinosaurs." $99 entitles you to publish an article a year, for life. $300 nets you unlimited articles published per year.
astroengine writes "President Barack Obama called for 'meaningful progress' on tackling climate change in his State of the Union speech in Washington, DC on Tuesday night. While acknowledging that 'no single event makes a trend,' the President noted that the United States had been buffeted by extreme weather events that in many cases encapsulated the predictions of climate scientists. 'But the fact is, the 12 hottest years on record have all come in the last 15. Heat waves, droughts, wildfires, and floods — all are now more frequent and intense. We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence. Or we can choose to believe in the overwhelming judgment of science — and act before it's too late,' Obama added." Other significant statements from Obama's speech: 34,000 troops coming back from Afghanistan over the next year; new gun regulations "deserve a vote"; rewards for schools that focus on STEM education; increases in tech research; a proposal to raise the minimum wage to $9.00/hr and tie it to inflation; and a proposal to use oil and gas revenues to fund a move away from oil and gas,

An anonymous reader writes "Ars reports on new legislation in the Missouri House of Representatives which is seeking equal time in the classroom for Intelligent Design, and to redefine science itself. You can read the text of the bill online. It uses over 600 words to describe Intelligent Design. Scientific theory, the bill says, is 'an inferred explanation of incompletely understood phenomena about the physical universe based on limited knowledge, whose components are data, logic, and faith-based philosophy.' It would require that 'If scientific theory concerning biological origin is taught in a course of study, biological evolution and biological intelligent design shall be taught.' The legislation's references to 'scientific theory' and 'scientific law' make it clear the writers don't have the slightest idea how science actually works. It also has this odd line near the end: 'If biological intelligent design is taught, any proposed identity of the intelligence responsible for earth's biology shall be verifiable by present-day observation or experimentation and teachers shall not question, survey, or otherwise influence student belief in a nonverifiable identity within a science course.'"
An anonymous reader writes "A group of researchers including Dr. H. Shaw Warren of Mass. General Hospital and Stanford genomics researcher Ronald W. Davis have published a paper challenging the effectiveness of the 'mouse model' as a basis for medical research, based on a decade-long study involving 39 doctors and scientists across the country. In clinical studies of sepsis (a severe inflammatory disorder caused by the immune system's abnormal response to a pathogen), trauma, and burns, the researchers found that certain drugs triggered completely different genetic responses in mice compared with humans. The Warren-Davis paper was rejected by both Science and Nature before its acceptance by the Proceedings of the National Academy of Science, perhaps suggesting the degree to which the 'mouse model' has become entrenched within the medical research community. Ninety five percent of the laboratory animals used in research are mice or rats. Mice in particular are ideal subjects for research: they are cheap to obtain and house, easy to handle, and share at least 80 percent of their genes with humans (by some reckoning, closer to 99 percent). Over the past twenty five years, powerful methods of genetically engineering mice by 'knocking out' individual genes have become widely adopted, so that use of mice for drug testing prior to human clinical trials has become standard procedure."
astroengine writes "In a recent poll funded by the non-profit Explore Mars, 71% of respondents agreed that the U.S. will send a human to Mars within the next two decades. Unfortunately, on average, the sample of 1,101 people surveyed thought the U.S. government allocated 2.4% of the federal budget to NASA — in reality it's only 0.5%. With this in mind, 75% of the respondents agreed/strongly agreed that NASA's budget should be increased to explore Mars through manned and robotic means."
New adosch writes "The Landsat Data Continuity Mission is now in orbit, after launching Monday from Vandenberg Air Force Base in Calif. After about three months of testing, the U.S. Geological Survey will take control and the mission, renamed Landsat 8, will extend more than 40 years of global land observations critical to energy and water management, forest monitoring, human and environmental health, urban planning, disaster recovery, and agriculture." We still need more new observation satellites to avoid losing Earth observing capabilities as the work horses of the NASA/USGS fleet die of old age.

The company announced a deal Monday with the Estonian Education ministry to trial a self-contained statistics program replacing the more traditional curriculum. “We are re-thinking computer education with the assumption that computers are the tools for computation,” said Mr. McLoone. “Schools are still focused on teaching hand calculating. Computation used to be the bottleneck. The hard part was solving the equations, so that was the skill you had to teach. These days that is the bit that computers can do. What computers can’t do is set up the problem, interpret the problem, think about validation and strategy. That is what we should be teaching and spending less time teaching children to be poor computers rather than good mathematicians.”'"
astroengine writes "The SETI Institute has launched a new website called 'Pluto Rocks!' intended to gather a public vote on the names of Pluto's smallest, and most recently discovered, moons P4 and P5. Discovered in 2011 and 2012 by Hubble, the two dinky satellites have concerned scientists managing the NASA New Horizons probe that will flyby the Plutonian system in 2015 — the presence of small rocky bodies in Pluto orbit might mean there is a significant collision risk to the high velocity spacecraft. This sinister back story will surely influence the naming outcome of the two new moons, where all the suggestions on Pluto Rocks! are related to Greek and Roman mythological characters from the underworld (but you can also make your own suggestions). If you want to get involved, there's also a special SETI Institute G+ Hangout planned for 11 a.m. PT Monday where two of the P4/P5 discovery scientists will hold a Q&A session."

In a statement, the pontiff said: 'After having repeatedly examined my conscience before God, I have come to the certainty that my strengths, due to an advanced age, are no longer suited to an adequate exercise of the Petrine ministry.' Resignations from the papacy are not unknown, but this is the first in the modern era, which has been marked by pontiffs dying while in office."
theodp writes "In an open letter on TechCrunch, Vivek Wadhwa calls on Congressman Luis Gutierrez to lift his 'hold on Silicon Valley' and stop tying immigration reform for highly-skilled STEM immigrants to the plight of undocumented immigrants. So, why should the STEM set get first dibs? 'The issues of high-skilled and undocumented immigrants are both equally important,' says Wadhwa, but 'the difference is that the skilled workers have mobility and are in great demand all over the world. They are getting frustrated and are leaving in droves.' Commenting on Gutierrez's voting record, Wadhwa adds, 'I would have voted for visas for 50,000 smart foreign students graduating with STEM degrees from U.S. universities over bringing in 55,000 randomly selected high-school graduates from abroad. The STEM graduates would have created jobs and boosted our economy. The lottery winners will come to the U.S. with high hopes, but will face certain unemployment and misery because of our weak economy.' So, should Gutierrez cede to Wadhwa's techies-before-Latinos proposal, or would this be an example of the paradox of virtuous meritocracy undermining equality of opportunity?"

According to Mother Jones, we now have more giant methane fireballs than any other country in the world and we can now see once dim North Dakota at night from space."
JG0LD writes "Students at a tiny Appalachian public school can't use Wi-Fi because any such network can throw the radio equivalent of a monkey wrench into a gigantic super-sensitive radio telescope just up the road. GBT's extraordinary sensitivity means that it's very susceptible to human-generated radio interference, according to site interference protection engineer Carla Beaudet. 'If there was no dirt between us and the transmitter, a typical access point ... would have to be on the order of 1,000,000 km [more than 620,000 miles, or about two and a half times the distance from the Earth to the Moon] distant to not interfere. Fortunately, we have mountains around us which provide lots of attenuation, so we're not seeing everything from everywhere,' she said. A standard Wi-Fi access point would wipe out a significant range of usable frequencies for the observatory. 'It simply ruins the spectrum for observations from 2400-2483.5MHz and from 5725-5875MHz for observational purposes,' wrote Beaudet."

An anonymous reader writes "[Ars Technica] recently reviewed the documentary The Revisionaries, which chronicles the actions of the Texas state school board as it attempted to rewrite the science and history standards that had been prepared by experts in education and the relevant subjects. For biology, the board's revisions meant that textbook publishers were instructed to help teachers and students 'analyze all sides of scientific information' about evolution. Given that ideas only reach the status of theory if they have overwhelming evidence supporting them, it isn't at all clear what 'all sides' would involve."
sciencehabit writes "A new study shows that ant pupae—a stage between larvae and adult—can communicate via sound, and that this communication can be crucial to their survival. The young insects have a specialized spike along their abdomen that they stroke with one of their hind legs, similar to dragging the teeth of a comb along the edge of a table. This noise serves primarily as an emergency beacon, allowing the ants to shout for help when being threatened by a predator."
First time accepted submitter Noctis-Kaban writes "Scientists in China have built and tested a radical new space drive. Although the thrust it produces may not be enough to lift your mobile phone, it looks like it could radically change the satellite industry. Satellites are just the start: with superconducting components, this technology could generate the thrust to drive everything from deep space probes to flying cars. And it all started with a British engineer whose invention was ignored and ridiculed in his home country."
sciencehabit writes "The ancestor of all placental mammals—the diverse lineage that includes almost all species of mammals living today, including humans—was a tiny, furry-tailed creature that evolved shortly after the dinosaurs disappeared, a new study suggests. The hypothetical creature, not found in the fossil record but inferred from it, probably was a tree-climbing, insect-eating mammal that weighed between 6 and 245 grams—somewhere between a small shrew and a mid-sized rat. It was furry, had a long tail, gave birth to a single young, and had a complex brain with a large lobe for interpreting smells and a corpus callosum, the bundle of nerve fibers that connects the left and right hemispheres of the brain. The period following the dinosaur die-offs could be considered a 'big bang' of mammalian diversification, with species representing as many as 10 major groups of placentals appearing within a 200,000-year interval."
astroengine writes "The Earth has one permanent moon — you know, 'The Moon' — but at any given time there are thought to be two temporary interlopers that were once asteroids, but get captured by our planet's gravity to become mini-moons for a few months or even years. They eventually get flung back out into interplanetary space. This ultimate 'catch and release' provides an interesting opportunity for any future asteroid mission. So now astronomers want to find them, possibly using the newly-minted Hubble-class spy telescopes donated to NASA by the National Reconnaissance Office."
astroengine writes "By focusing the Green Bank radio telescope on stars hosting (candidate) exoplanets identified by NASA's Kepler space telescope, it is hoped that one of those star systems may also play host to a sufficiently evolved alien race capable of transmitting radio signals into space. But in a study headed by ex-SETI chief Jill Tarter, the conclusion of this first attempt is blunt: 'No signals of extraterrestrial origin were found.' But this is the just first of the 'directed' SETI searches that has put some very important limits on the probability of finding sufficiently advanced alien civilizations in our galaxy."
Hugh Pickens writes writes "Embry-Riddle Aeronautical University has announced plans to launch the nation's first ever bachelor's degree in Commercial Space Operations to supply the commercial spaceflight industry with skilled graduates in the areas of space policy, operations, regulation and certification, as well as space flight safety, and space program training, management and planning. The rapid expansion of commercial spaceflight operations is fostered by NASA's commercial cargo and crew development programs and by entrepreneurs developing capabilities for suborbital spaceflight, orbital space habitats, space resource prospecting and other commercial ventures. 'Embry-Riddle's new Commercial Space Operations degree is one of the most innovative non-engineering degrees in the aerospace industry,' says program coordinator Lance Erickson, a professor of applied aviation sciences at Embry-Riddle. 'When we were planning this degree, our advisers from the commercial space industry said they couldn't wait to hire our graduates.'"
ananyo writes "How open do researchers want open-access papers to be? Apparently, not that open — when given a choice of licenses, most opt to limit the use of data and words in their open-access publications, according to figures released by the open-access journal Scientific Reports. Since July 2012 the journal has been offering researchers a choice of three types of license. The first, most liberal license, CC-BY, allows anyone, even commercial organizations, to re-use it. A more restrictive version, CC-BY-NC-SA, lets others remix, tweak and build on work if they give credit to the original author, but only for non-commercial (NC) purposes, and only if they license what they produce under the same terms (SA, or 'share-alike'). A third licence, CC-BY-NC-ND, is the most restrictive, allowing others to download and share work, but not to change it in any way (ND, 'no derivative works'), or use it commercially. The results from Scientific Reports shows that, for the 685 papers accepted by the journal, authors chose either of the more restrictive licences 95% of the time — and the most restrictive, CC-BY-NC-ND, 68% of the time."
