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."
