WINSTON-SALEM, N.C. – Nov. 20, 2012 – If you are among the 50 percent of Americans who suffer from insomnia, then you have probably tried everything – from warm milk to melatonin pills or prescription medications to induce sleep – with varying degrees of success and side effects. But what if sleep could be achieved not by a substance, but through 'balancing' brain activity? Researchers at Wake Forest Baptist Medical Center have conducted a pilot clinical study to determine whether a non-invasive approach, that uses musical tones to balance brain activity, can 'reset' ...

Millbrook, N.Y. -- In the northern hardwood forest, climate change is poised to reduce the viability of the maple syrup industry, spread wildlife diseases and tree pests, and change timber resources. And, according to a new BioScience paper just released by twenty-one scientists, without long-term studies at the local scale—we will be ill-prepared to predict and manage these effects. Following an exhaustive review of more than fifty years of long term data on environmental conditions at the Hubbard Brook Experimental Forest, located in the White Mountains of New Hampshire, ...

Do birds change their tune in response to urban noise? It depends on the bird species, according to Dr. Alejandro Ariel Ríos-Chelén from the Universidad Nacional Autónoma de México and colleagues. Their work shows that while some birds do adapt their songs in noisy conditions by means of frequency changes, others like the vermilion flycatchers adapt their song by means of changes in song lengths. The work is published online in Springer's journal, Behavioral Ecology and Sociobiology. Birds use their songs during social interactions to attract females and repel intruders. ...

UNIQUE research conducted by a University of Huddersfield professor confirms just how successfully the 2012 Olympics and Paralympics were designed, organised and delivered. His findings will reveal to planners of the 2016 Games in Brazil just what they must do to meet or exceed the standards set by London. Professor David Bamford, an expert in the theory of operations management and how it can be applied to the sports arena, was granted full access to the Paralympics village in London and with his team of researchers he quizzed hundreds of athletes, seeking their views ...

NEW YORK, November 20, 2012 – Researchers at the Polytechnic Institute of New York University (NYU-Poly) have published findings that further illuminate the emerging field of ethorobotics — the study of bioinspired robots interacting with live animal counterparts. Maurizio Porfiri, associate professor of mechanical and aerospace engineering at NYU-Poly, doctoral candidates Vladislav Kopman and Jeffrey Laut and research scholar Giovanni Polverino studied the role of real-time feedback in attracting or repelling live zebrafish in the presence of a robotic fish. Their ...

Mobile telephone operators should verify the age of children and youngsters when they access multimedia services by having a record of users' dates of birth. This is one of the recommendations in a report by researchers from the Polytechnic University of Valencia (Spain), that also suggest content classifications for mobiles by age, like in the case of video games. "Verification of age upon access to mobile phone services is not effective because the child can also falsify their age by checking a different box," as explained to SINC by María de Miguel Molina, lecturer ...

Scientists at Imperial College London have developed a system to quickly detect trace amounts of chemicals like pollutants, explosives or illegal drugs. The new system can pick out a single target molecule from 10 000 trillion water molecules within milliseconds, by trapping it on a self-assembling single layer of gold nanoparticles. The team of scientists, all from the Department of Chemistry at Imperial, say this technology opens the way to develop devices that are compact, reusable and easy to assemble, and could have a range of uses including detecting illegal drugs, ...

HEIDELBERG, 20 November 2012 – Scientists have engineered bacteria that are capable of sacrificing themselves for the good of the bacterial population. These altruistically inclined bacteria, which are described online in the journal Molecular Systems Biology, can be used to demonstrate the conditions where programmed cell death becomes a distinct advantage for the survival of the bacterial population. "We have used a synthetic biology approach to explicitly measure and test the adaptive advantage of programmed bacterial cell death in Escherichia coli," said Lingchong ...

November 20, 2012 -- Results of a new study by researchers at Columbia University's Mailman School of Public Health indicate that a developmental pattern of impulsiveness in young males is linked with gambling problems in late adolescence. Respondents considered to be in the high impulsivity track as early as first grade doubled the odds of meeting criteria for at-risk/problem gambling, and tripled the odds of meeting criteria for problem gambling. The study is the first to link a developmental pattern of impulsivity -- defined as a tendency to make rush decisions without ...

Viruses can be elusive quarry. RNA viruses are particularly adept at defeating antiviral drugs because they are so inaccurate in making copies of themselves. With at least one error in every genome they copy, viral genomes are moving targets for antiviral drugs, creating resistant mutants as they multiply. In the best-known example of success against retroviruses, it takes multiple-drug cocktails to corner HIV and narrow its escape route. Rather than target RNA viruses themselves, aiming at the host cells they invade could hold promise, but any such strategy would have ...

Philadelphia, Pa. (November 16. 2012) – Meningiomas are a common type of benign brain tumor that sometimes grows dramatically in pregnant women. A new study suggests that this sudden tumor growth likely results from "hemodynamic changes" associated with pregnancy, reports the November issue of Neurosurgery, official journal of the Congress of Neurological Surgeons. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. The study also identifies some key characteristics associated with rapid growth of meningiomas in pregnant women. ...

New research on posttraumatic stress disorder (PTSD) in soldiers challenges popular assumptions about the origins and trajectory of PTSD, providing evidence that traumatic experiences in childhood - not combat - may predict which soldiers develop the disorder. Psychological scientist Dorthe Berntsen of Aarhus University in Denmark and a team of Danish and American researchers wanted to understand why some soldiers develop PTSD but others don't. They also wanted to develop a clearer understanding of how the symptoms of the disorder progress. "Most studies on PTSD in ...

HOUSTON -- (Nov. 19, 2012) -- Rice University scientists have unveiled a revolutionary new technology that uses nanoparticles to convert solar energy directly into steam. The new "solar steam" method from Rice's Laboratory for Nanophotonics (LANP) is so effective it can even produce steam from icy cold water. Details of the solar steam method were published online today in ACS Nano. The technology has an overall energy efficiency of 24 percent. Photovoltaic solar panels, by comparison, typically have an overall energy efficiency around 15 percent. However, the inventors ...

PHILADELPHIA — Several fatal brain disorders, including Parkinson's disease, are connected by the misfolding of specific proteins into disordered clumps and stable, insoluble fibrils called amyloid. Amyloid fibrils are hard to break up due to their stable, ordered structure. For example, α-synuclein forms amyloid fibrils that accumulate in Lewy Bodies in Parkinson's disease. By contrast, protein clumps that accumulate in response to environmental stress, such as heat shock, possess a less stable, disordered architecture. Hsp104, an enzyme from yeast, breaks up both ...

LEXINGTON, Ky. (Nov. 19, 2012) — A new study review published by the University of Kentucky found that music therapy can be beneficial to patients before, during and after a surgical procedure and may reduce pain and recovery time. Published in the Southern Medical Journal, the review examined the use of music in the preoperative, intraoperative and postoperative stages of the surgical process, and music was shown to have positive results in all three stages. Patients were less anxious before the procedure and recovered more quickly and satisfactorily after by being exposed ...

"Who in his wildest dreams could have imagined that, beneath the crust of our Earth, there could exist a real ocean...a sea that has given shelter to species unknown?" So wrote Jules Verne almost 150 years ago in A Journey to the Center of the Earth. Verne probably couldn't have imagined the diversity of life that researchers observe today under the ocean floor. Scientists affiliated with the National Science Foundation (NSF) Center for Dark Energy Biosphere Investigations (C-DEBI) will discuss recent progress in understanding life beneath the seafloor at the American ...

Seattle Children's Research Institute, together with an international team of scientists and clinicians from 22 other institutions, have identified two genetic risk factors for the most common form of non-syndromic craniosynostosis, a birth defect in which the bony plates of an infant's skull prematurely fuse. The condition is known as sagittal craniosynostosis and often results in an abnormal head shape and facial features. The study identified two genes (BMP2 and BBS9) associated with sagittal craniosynostosis that are known to be involved in broader skeletal development. Results ...

Washington, DC — A team of scientists, including Carnegie's Conel Alexander and Jianhua Wang, studied the hydrogen in water from the Martian interior and found that Mars formed from similar building blocks to that of Earth, but that there were differences in the later evolution of the two planets. This implies that terrestrial planets, including Earth, have similar water sources--chondritic meteorites. However, unlike on Earth, Martian rocks that contain atmospheric volatiles such as water, do not get recycled into the planet's deep interior. Their work will be published ...
