Superconductors: Physical link to strange electronic behavior Scientists have new clues this week about one of the baffling electronic properties of the iron-based high-temperature superconductor barium iron nickel arsenide. Scientists have the first evidence, based on sophisticated neutron measurements, of a link between magnetic properties and the (...) [Science daily]  Singing the same tune: Scientists develop novel ways of separating birdsong sources A new study could greatly improve current methods of localizing birdsong data. The study demonstrates the validity of using approximate maximum likelihood (AML) algorithms to determine the direction of arrival (DOA) of birdsong (...) [Science daily] VIDEO: The challenge of tackling Ebola Scientists have been aware of Ebola since the mid-1970s, but so far no vaccine or cure has been developed. [BBC News Africa] Fear of losing money, not spending habits, affects investor risk tolerance Scientists analyzed the causes of risk tolerance and found that loss aversion, or the fear of losing money, is the primary factor that explains investors' risk tolerance. [Science daily] Finding quantum 'lines of desire': Physicists track quantum system's wanderings through quantum state space What paths do quantum particles, such as atoms or photons, follow through quantum state space? Scientists have used an "artificial atom" to continuously and repeatedly record the paths through quantum state space. From the cobweb of a million paths, a most likely path between two quantum states (...) [Science daily] Spin-based electronics: New material successfully tested Spintronics is a new field of electronics, using electron spin rather than motion. This technology requires insulating components that can control this quantum property. Scientists have shown experimentally that a novel material shows all the required (...) [Science daily] IBM to make free supercomputing power available to sustainability scientists In support of the updated Climate Data Initiative announced by the White House today, IBM (NYSE: IBM ) will provide eligible scientists studying climate change-related issues with free access to dedicated virtual supercomputing and a platform to engage the public in their research. Each (...) [WebWire Internet technology] IBM to make free supercomputing power available to sustainability scientists In support of the updated Climate Data Initiative announced by the White House today, IBM (NYSE: IBM ) will provide eligible scientists studying climate change-related issues with free access to dedicated virtual supercomputing and a platform to engage the public in their research. Each (...) [WebWire Computer networks] A transistor-like amplifier for single photons Scientists have achieved a twentyfold amplification of single-photon signals with the help of an ultracold quantum gas. [Science daily] New tools help neuroscientists analyze 'big data' New technologies for monitoring brain activity are generating unprecedented quantities of information. That data may hold new insights into how the brain works -- but only if researchers can interpret it. To help make sense of the data, neuroscientists can now harness the power of distributed (...) [Science daily] Electronic aura could be answer to lost passwords Cambridge scientist plans to develop device that would store electronic details and keep them secure Continue reading... [The Guardian] Mobile test illuminates risk taking Specially designed mobile games can help scientists answer important questions about cognition, a team finds. [BBC] Mobile test illuminates risk taking Specially designed mobile games can help scientists answer important questions about cognition, a team finds. [BBC News] Open thread: if Tomorrow's World came back, what should it be like? Former presenter Maggie Philbin thinks the BBC should revive its popular science show, but how? Continue reading... [The Guardian] Gene changes in breast cancer cells pinpointed with new computational method Computer scientists working with high-throughput data generated by breast cancer biologists have devised a computational method to determine how gene networks are rewired as normal breast cells turn malignant and as they respond to potential cancer therapy (...)
