A team of telecommunications engineers from the University of Jaen (UJA) has created a new method to automatically detect and identify the musical notes in an audio file and generate sheet music. The system identifies the notes even when the type of instrument, musician, type of music or recording studio conditions vary.

Agricultural Research Service (ARS) scientists are helping U.S. Nuclear Regulatory Commission (NRC) experts model the movement of radioactive materials in the soil. Their findings can be used to fine-tune the risk assessment studies that are an essential component in the development of commercial nuclear facilities.
Writing in the International Journal of Electronic Marketing and Retailing, researchers from the US and Germany point out an inherent flaw in the financial industry adopting biometric logins to boost security in that the advent of mobile devices, such as netbooks, PDAs, and smart phones might make biometric logins impossible when one is on the move.
In a major breakthrough for wheat farmers in salt-affected areas, CSIRO researchers have developed a salt tolerant durum wheat that yields 25 per cent more grain than the parent variety in saline soils.Recent field trials in northern New South Wales proved that durum wheat varieties containing new salt tolerant genes outperformed the other varieties in saline soils.
ANN ARBOR, Mich.---As a way to simplify lab-on-a-chip devices that could offer quicker, cheaper and more portable medical tests, University of Michigan researchers have created microfluidic integrated circuits.
Just as electronic circuits intelligently route the flow of electricity on computer chips without external controls, these microfluidic circuits regulate the flow of fluid through their devices without instructions from outside systems.
A paper on the technology is newly published online in Nature Physics.
African farmers risk being forced from their lands by investors or government projects as global demand for biofuels encourages changes in crop cultivation.
Research from the University of Edinburgh has found that livelihoods may be put at risk if African farmland is turned over to growing crops for biofuel.
A new study links nicotine poisoning with weight gain, and concludes that active smokers, not only those who stop, put on more weight than non-smokers. After four years of analysis in the University of Navarra, those who put on least weight were those who had never smoked.
INDIANAPOLIS – Less than a quarter of Americans want no changes to the health care legislation signed into law by the president last month but there may be more common ground with other Americans than many think, according to the latest national survey by researchers from Indiana University's Center for Health Policy and Professionalism Research (CHPPR).
When survey respondents were asked how they viewed the new law:
Estimating crop yields based on available water in semi-arid regions has been made easier for several hundred farmers who are using a special calculator computer program developed by an Agricultural Research Service (ARS) scientist.
Several hundred farmers in the Central Great Plains have picked up a copy of the device, called the MultiCalculator CD, at field days and other outreach meetings, according to David Nielsen, the agronomist who developed it at the ARS Central Great Plains Research Station in Akron, Colo.
Family members who provide care to relatives with dementia, but do not have formal training, frequently experience overwhelming stress that sometimes leads to breakdowns or depression, according to Penn State and Benjamin Rose Institute researchers. Interventions to alleviate this stress are not always effective, leaving caregivers isolated to deal with their stresses.
OAK RIDGE, Tenn., April 22, 2010 -- Mimicking the human nervous system for bionic applications could become a reality with the help of a method developed at Oak Ridge National Laboratory to process carbon nanotubes.
PASADENA, Calif.—A group of scientists led by researchers from the California Institute of Technology (Caltech) has engineered a type of artificial optical material—a metamaterial—with a particular three-dimensional structure such that light exhibits a negative index of refraction upon entering the material. In other words, this material bends light in the "wrong" direction from what normally would be expected, irrespective of the angle of the approaching light.
ANN ARBOR, Mich.---Heating and squishing microalgae in a pressure-cooker can fast-forward the crude-oil-making process from millennia to minutes.
University of Michigan professors are working to understand and improve this procedure in an effort to speed up development of affordable biofuels that could replace fossil fuels and power today's engines.
They are also examining the possibility of other new fuel sources such as E. coli bacteria that would feed on waste products from previous bio-oil batches.
Aydogan Ozcan, whose invention of a novel lensless imaging technology for use in telemedicine could radically transform global health care, has now taken his work a step further ― or tinier: The UCLA engineer has created a miniature microscope, the world's smallest and lightest for telemedicine applications.
PORTLAND, Ore. -- A multi-site study led by an Oregon Health & Science University Knight Cancer Institute researcher has identified set criteria that could be used to help identify physicians who might benefit from additional training in interpreting screening mammograms.
