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."
A few weeks ago you had the chance to ask Jack Horner about dinosaurs, science funding, and extinction level events. He's sent back his responses and commented: "Very impressive audience you have!" Read below for more flattery and his answers to your questions.
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,
coondoggie writes "The asteroid NASA says is about the half the size of a football field that will blow past Earth on Feb 15 could be worth up to $195 billion in metals and propellant. That's what the scientists at Deep Space Industries, a company that wants to mine these flashing hunks of space materials, thinks the asteroid known as 2012 DA14 is worth — if they could catch it."
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."
