Chemists at Queen's University Belfast have devised a novel, environmentally friendly technique, which allows the rapid production of Metal-Organic Frameworks porous materials (MOFs). These revolutionary nanomaterials have the potential to transform hazardous gas storage, natural gas vehicles and drug delivery and have the highest surface-area of any known substance. A sugar-lump sized piece of MOF material can have the same surface area as a football pitch. Until now MOF manufacturing techniques have been limited as they are costly, slow and require large quantities ...

University of Luxembourg's Laboratory for Photovoltaics has established a method to observe and prevent solar cell degradation before solar cell production is finished, which has implications for the solar cell manufacturing industry since chemical damage to solar cells can occur quickly. Solar panels are capable of converting light energy from the sun into electrical energy because they contain solar cells – the "power generators" responsible for the energy in solar panels. Thin film solar cells have a coating that is responsible for absorbing the sun's energy, but ...

A team of international researchers has provided the first comprehensive DNA evidence that the Addis Ababa lion in Ethiopia is genetically unique and is urging immediate conservation action to preserve this vulnerable lion population. While it has long been noted that some lions in Ethiopia have a large, dark mane, extending from the head, neck and chest to the belly, as well as being smaller and more compact than other lions, it was not known until now if these lions represent a genetically distinct population. The team of researchers, led by the University of York, ...

Philadelphia, PA, October 11, 2012 – A paper by Shizhong Han and colleagues in the current issue of Biological Psychiatry implicates a new gene in the risk for cannabis dependence. This gene, NRG1, codes for the ErbB4 receptor, a protein implicated in synaptic development and function. The researchers set out to investigate susceptibility genes for cannabis dependence, as research has already shown that it has a strong genetic component. To do this, they employed a multi-stage design using genetic data from African American and European American families. In the first ...

Researchers from North Carolina State University have created flower-like structures out of germanium sulfide (GeS) – a semiconductor material – that have extremely thin petals with an enormous surface area. The GeS flower holds promise for next-generation energy storage devices and solar cells. "Creating these GeS nanoflowers is exciting because it gives us a huge surface area in a small amount of space," says Dr. Linyou Cao, an assistant professor of materials science and engineering at NC State and co-author of a paper on the research. "This could significantly increase ...

WASHINGTON, Oct. 11—Spiders use their silk to catch lunch. Now physicists are using it to catch light. New research shows that natural silk could be an eco-friendly alternative to more traditional ways of manipulating light, such as through glass or plastic fiber optic cables. Two teams independently exploring possible applications for the material's photonic talents will present their latest breakthroughs at the Optical Society's (OSA) Annual Meeting, Frontiers in Optics (FiO) 2012, to be held next week in Rochester, N.Y. Biomedical engineer Fiorenzo Omenetto of Tufts ...

Hospital superbugs can float on air currents and contaminate surfaces far from infected patients' beds, according to University of Leeds researchers. The results of the study, which was funded by the Engineering and Physical Sciences Research Council (EPSRC), may explain why, despite strict cleaning regimes and hygiene controls, some hospitals still struggle to prevent bacteria moving from patient to patient. It is already recognised that hospital superbugs, such as MRSA and C-difficile, can be spread through contact. Patients, visitors or even hospital staff can inadvertently ...

EAST LANSING, Mich. — Contrary to past research, private school students in India do not outperform their counterparts in public schools, finds a new study by a Michigan State University education researcher. The study challenges the claim that private schools are superior – a hot issue in India and other developing countries that are expanding K-12 educational offerings. During the past decade, some 40 million children have entered India's education system, giving rise to a growth in privately run schools. "Our study finds no consistent benefit of attending a private ...

AMHERST, Mass. – Until recently, medical researchers had little hope of experimentally manipulating naïve T cells to study their crucial roles in immune function, because they were largely impenetrable, says polymer scientist Gregory Tew: "So far off limits we could not readily get inside to investigate their workings." Now, he and colleagues including immunologist Lisa Minter have found a way not only to get inside naïve T cells, but to deliver bio-active cargo such as proteins and synthetic molecules across that long-locked cell membrane, by using a new synthetic protein ...

WASHINGTON and NEW YORK – A new report finds that Texas policies to exclude Planned Parenthood clinics from a state family planning program – the Women's Health Program (WHP) – would result in leaving tens of thousands of women unable to get care. "Deteriorating Access to Women's Health Services in Texas: Potential Effects of the Women's Health Program Affiliate Rule," released by the Geiger Gibson/RCHN Community Health Foundation Research Collaborative in the Department of Health Policy of the George Washington University School of Public Health and Health Services, ...

Scientists have proved a 60-year-old theory about how nerve signals are sent around the body at varying speeds as electrical impulses. Researchers tested how these signals are transmitted through nerve fibres, which enables us to move and recognise sensations such as touch and smell. The findings from the University of Edinburgh have validated an idea first proposed by Nobel laureate Sir Andrew Huxley. It has been known for many years that an insulating layer – known as myelin – which surrounds nerve fibres is crucial in determining how quickly these signals are ...

Differing contributions of freshwater from glaciers and streams to the Arctic and Southern oceans appear to be responsible for the fact that the majority of microbial communities that thrive near the surface at the Poles share few common members, according to an international team of researchers, some of whom were supported by the National Science Foundation (NSF). In a paper published in the Oct. 8 edition of the Proceedings of the National Academy of Sciences (PNAS), the researchers report that only 25 percent of the taxonomic groups identified by genetic sequencing ...

Domestic violence rates rose by an average of 30 percent each time England won or lost their games during the 2010 World Cup, but draws had little impact on the statistics. Those are the key findings of research carried out by statistician Professor Allan Brimicombe and BBC News journalist Rebecca Cafe and published in the October issue of Significance, the magazine of The Royal Statistical Society and the American Statistical Association. As a consequence of this and previous research, Professor Brimicombe believes there is a strong case for schools to educate pupils ...

A new study improves our understanding of plasma sources, a state of matter similar to gas in which a certain portion of the particles are ionised and which are used for example in plasma display panels. These results revealed by physicists from the University of Greifswald, Germany, Robert Wild and Lars Stollenwerk, and are about to be published in EPJ D. Under certain circumstances, plasma tends to form structures such as filaments of electric discharge akin to mini-lightning. The authors specifically investigated a so-called barrier discharge, which features at least ...

Babies born prematurely to low-income parents have a disproportionately high risk for developing dangerous brain bleeds that require multiple surgeries and extensive follow-up, according to a small Johns Hopkins Children's Center study. The findings - published online Sept. 28 in the journal Pediatric Neurosurgery and based on an analysis of 38 patients referred to Johns Hopkins for treatment of brain hemorrhages related to premature birth - offer a sobering reminder of the role socio-economic factors can play in health outcomes, the researchers say. The link between ...

Amsterdam, NL, 11 October, 2012 – Dopamine is a neurotransmitter that is associated with emotions, movement, and the brain's pleasure and reward system. In the current issue of Advances in Neuroimmune Biology, investigators provide a broad overview of the direct and indirect role of dopamine in modulating the immune system and discuss how recent research has opened up new possibilities for treating diseases such as Parkinson's and Alzheimer's disease, schizophrenia, multiple sclerosis or even the autoimmune disorders. Dopamine can be synthesized not only in neurons, ...

WASHINGTON, D.C. – The Presidential Commission for the Study of Bioethical Issues today released its report concerning genomics and privacy. The report, Privacy and Progress in Whole Genome Sequencing, concludes that to realize the enormous promise that whole genome sequencing holds for advancing clinical care and the greater public good, individual interests in privacy must be respected and secured. As the scientific community works to bring the cost of whole genome sequencing down from millions per test to less than the cost of many standard diagnostic tests today, ...

A new breakthrough in solar technology means portable electronic devices such as e-book readers could soon be re-charged on the move in low light levels and partial shading. Scientists from the University of Warwick, in collaboration with spin-out company Molecular Solar, have created an organic solar cell that generates a sufficiently high voltage to recharge a lithium-ion battery directly, without the need to connect multiple individual cells in series. Modules of these high voltage cells perform well in different light conditions including partial shade making them ...

This press release is available in Spanish. To help increase the survival of newborn piglets, U.S. Department of Agriculture (USDA) scientists have developed a new method that predicts animals' mortality and nursing ability. Physiologist Jeffrey Vallet and his colleagues at the Agricultural Research Service (ARS) Roman L. Hruska U.S. Meat Animal Research Center (USMARC) in Clay Center, Neb., call the measuring technique the "immunocrit," which determines whether preweaning piglets receive adequate colostrum from the sow. ARS is USDA's principal intramural scientific research ...

NEW YORK (October 11, 2012)— A new study by the Wildlife Conservation Society and James Cook University says that coral reefs in Aceh, Indonesia are benefiting from a decidedly low-tech, traditional management system that dates back to the 17th century. Known as "Panglima Laot" – the customary system focuses on social harmony and reducing conflict among communities over marine resources. According to the study, reefs benefitting from Panglima Laot contain as much eight time more fish and hard-coral cover due to mutually agreed upon gear restrictions especially prohibiting ...

The Automotive Recyclers Association (ARA) today announced its support of the National Highway Traffic Safety Administration's (NHTSA) efforts to warn consumers about those who would promote the sale and use of counterfeit air bags. ARA has long cautioned the automotive repair industry community and consumers about the dangers of using counterfeit air bags, as well as the alarming practice of omitting airbags altogether in repairs. In fact, in 2009, NHTSA reviewed fatal accidents in a 5 year period and found that airbags were missing in 18 percent of the crashed vehicles ...

MAYWOOD, Il. - When hospital patients have to be readmitted soon after discharge, hospitals look bad. And in addition to reflecting poorly on a hospital's quality of care, a high readmission rate also can result in reduced Medicare reimbursements, under provisions now taking effect under the 2010 health care law. But a study of spine surgery patients has found that the standard method used to calculate readmission rates is a misleading indicator of hospital quality. Loyola University Medical Center neurosurgeon Beejal Amin, MD, and colleagues found that 25 percent of ...

MINNEAPOLIS – New research reveals that stroke may be affecting people at a younger age. The study is published in the October 10, 2012, online issue of Neurology®, the medical journal of the American Academy of Neurology. "The reasons for this trend could be a rise in risk factors such as diabetes, obesity and high cholesterol," said study author Brett Kissela, MD, MS, with the University of Cincinnati College of Medicine in Ohio and a Fellow of the American Academy of Neurology. "Other factors, such as improved diagnosis through the increased use of MRI imaging may ...
