WEST LAFAYETTE, Ind. – Researchers have developed an aluminum alloy that could be used in a new type of mobile technology to convert non-potable water into drinking water while also extracting hydrogen to generate electricity. Such a technology might be used to provide power and drinking water to villages and also for military operations, said Jerry Woodall, a Purdue University distinguished professor of electrical and computer engineering. The alloy contains aluminum, gallium, indium and tin. Immersing the alloy in freshwater or saltwater causes a spontaneous reaction, ...

Survey Reveals High Rate of Criminal Convictions Among Nursing Home Employees In an unprecedented examination of the nursing home industry, the federal Department of Health and Human Services (DHHS) surveyed hundreds of nursing homes around the country to find that a whopping 92 percent of them employed at least one worker with a criminal conviction. Perhaps even more disturbing is the fact that almost half of all nursing home facilities in the country employ five or more people with at least one conviction each. An extreme example of the problem is seen in one particular ...

Think of a dependent person, and you think of someone who's needy, high-maintenance, and passive. That's how many psychologists and therapists think of them, too; passivity is key. But dependency is actually more complex and can even have active, positive aspects, writes Robert Bornstein of Adelphi University, the author of a new article published in Current Directions in Psychological Science, a journal of the Association for Psychological Science. Bornstein was sent towards a different concept of dependency by a series of experiments he did in graduate school. He paired ...

Student Athlete Concussion Policy and Law in Indiana In Indiana, sports are king. From basketball to auto racing and football, sports are in our blood. Not only are sports great exercise for our kids, they can also help form important social skills, like teamwork and cooperation. But there are risks to this childhood fun. Every year in the U.S over 135,000 children aged five to 18 are treated in emergency rooms for sports-related concussions, according to the Centers for Disease Control and Prevention. But many concussions go untreated every year, based on an outdated ...

Peripheral arterial disease (PAD) is an indicator for coronary and carotid arterial disease and carries inherent risks of claudication and amputation. PAD screening has increased dramatically, particularly among cardiologists, while vascular surgery has demonstrated the greatest growth in revascularization procedures treating PAD, according to research being presented at the 2011 American Roentgen Ray Society's annual meeting. The study was performed at Rhode Island Hospital in Providence, RI. CPT codes were extracted for lower extremity vascular noninvasive physiologic ...

MDCT arthrography is better than MR arthrography for diagnosing glenoid rim osseous lesions, lesions that have been identified as potential causes of recurrence after shoulder surgery, according to a new study. The study, done at the Hopital Sainte Marguerite in Marseille, France, included 40 patients scheduled for shoulder surgery. All patients had both an MDCT arthrography (MDCTA) and an MR arthrography exam (the current standard exam). "Our study found that MDCTA was as accurate as MR arthrography for the study of labro-ligamentous injuries, glenoid cartilage lesions ...

Bedsores Can Be a Tell-Tale Sign of Nursing Home Neglect As our population ages, the numbers of elderly people needing full-time care in nursing homes and residential care facilities is rapidly increasing. An increase in residents, however, does not necessarily translate into an increase in the number of caregivers, and the incidence of cases of nursing home abuse and neglect is on the rise. A huge number of those cases involve infirm patients affected by painful and sometimes deadly bedsores. Bedsores -- also known as "pressure sores" or "decubitus ...

A new study shows that susceptibility-weighted imaging (SWI) is a powerful tool for characterizing infarctions (stroke) in patients earlier and directing more prompt treatment. In the United States, stroke is the third leading cause of death and overall affects almost one million people each year, said Dr. Mark D. Mamlouk, lead author of the study at the University of California, Irvine. He states, "There are different causes of stroke of which the thromboembolic (clot) subtype is one of the most common." Traditionally, SWI, which is a specific MRI sequence, has been ...

Recent studies have shown that a 64-detector CT angiography utilizing prospective electrocardiographic (ECG) gating produces a quality image but considerably reduced patient radiation dose when compared to retrospective ECG gating, according to research being presented at the 2011 American Roentgen Ray Society's annual meeting. The study was conducted in the Department of Radiology at the University Hospitals Case Medical Center, in Cleveland, OH. Researchers evaluated 29 patients who underwent prospectively-gated 100 kV whole chest CT for preoperative cardiothoracic ...

Patients are at risk of life-threatening injuries from a device meant to protect healthy tissue from unwanted radiation during cancer treatment. The medical device, called the Axxent FlexiShield Mini, has been classified as the most serious type of recall. According to the U.S. Food and Drug Administration (FDA), recalls of this level involve "situations in which there is a reasonable probability that use of these products will cause serious adverse health consequences or death." "Unsurprisingly, the shield was approved by the FDA via an abbreviated ...

The use of breast shields is the technique of choice to protect the breasts of women from radiation exposure while undergoing chest CT examinations, according to a new study. The use of CT has grown exponentially which brings into question the level of radiation exposure to patients. Recently the International Commission of Radiation Protection (ICRP) increased the tissue weighting factor for the breast from 0.05 to 0.1 noting that breast tissue is even more sensitive to radiation exposure than previously thought, said Rafel Tappouni, MD, the lead author of the study. ...

The Meathook Galaxy, or NGC 2442, in the southern constellation of Volans (The Flying Fish), is easily recognised for its asymmetric spiral arms. The galaxy's lopsided appearance is thought to be due to gravitational interactions with another galaxy at some point in its history — though astronomers have not so far been able to positively identify the culprit. This broad view, taken by the Wide Field Imager on the MPG/ESO 2.2-metre telescope at La Silla, Chile, very clearly shows the double hook shape that gives the galaxy its nickname. This image also captures several ...

Bethesda, MD—With growing evidence of the link between exposure to toxic chemicals and chronic diseases, especially in children, the United States needs to step up its efforts to protect the public from hazardous chemicals, say researchers writing in the May issue of Health Affairs. The Environmental Protection Agency (EPA), stymied by the outdated Toxic Substances Control Act, must seek partners in academia to help evaluate the risks of industrial chemicals on the market today, say Sarah A. Vogel of the Johnson Family Foundation and Jody Roberts of the Chemical Heritage ...

The Meathook Galaxy, or NGC 2442, has a dramatically lopsided shape. One spiral arm is tightly folded in on itself and host to a recent supernova, while the other, dotted with recent star formation, extends far out from the nucleus. The NASA/ESA Hubble Space Telescope and the MPG/ESO 2.2-metre telescope have captured two contrasting views of this asymmetric spiral galaxy. The Meathook Galaxy, or NGC 2442, in the southern constellation of Volans (The Flying Fish), is easily recognised for its asymmetric spiral arms. The galaxy's lopsided appearance is thought to be due ...

A group of 12 biology educators at US colleges and universities that teach mostly undergraduates argues in the May issue of BioScience for coordinating networks to expand the study and teaching of ecology conducted at these institutions. The group, which has launched a network dedicated to continental-scale observations, argues that better coordination of current research efforts will allow "transformative contributions" cost-effectively, while also providing valuable educational experiences for undergraduates. Most ecological research in the United States is conducted ...

A study of older married couples that gives new meaning to the matrimonial adage "for better or worse" finds that spouses have a much greater impact on their partner's health than previously known. The study, published in the current issue of the American Psychological Association's journal Health Psychology, finds strong associations between the physical and emotional health of older married couples – and provides important new information on the psychological toll of physical limitations in old age. Researchers from the University of British Columbia and Pennsylvania ...

Weizmann Institute scientists have added another piece to the obesity puzzle, showing how and why a certain protein that is active in a small part of the brain contributes to weight gain. This research appeared today in Cell Metabolism. Prof. Ari Elson and his team in the Institute's Molecular Genetics Department made the discovery when working with female mice that were genetically engineered to lack this protein, called protein tyrosine phosphatase epsilon (PTPe, for short). The scientists had originally intended to investigate osteoporosis, and thus, they also removed ...

Evolution is providing the inspiration for University of Adelaide computer science research to find the best placement of turbines to increase wind farm productivity. Senior Lecturer Dr Frank Neumann, from the School of Computer Science, is using a "selection of the fittest" step-by-step approach called "evolutionary algorithms" to optimise wind turbine placement. This takes into account wake effects, the minimum amount of land needed, wind factors and the complex aerodynamics of wind turbines. "Renewable energy is playing an increasing role in the supply of energy ...

A new study from Karolinska Institutet in Sweden shows that the brain has built-in mechanisms that trigger an automatic reaction to someone who refuses to share. The reaction derives from the amygdala, an older part of the brain. The subjects' sense of justice was challenged in a two-player money-based fairness game, while their brain activity was registered by an MR scanner. When bidders made unfair suggestions as to how to share the money, they were often punished by their partners even if it cost them. A drug that inhibits amygdala activity subdued this reaction to unfairness. The ...

In an interview for DIalAflight's Red Chair TV Joanna Cooke of the Thailand Tourist Board agreed that the press overhyped last year's protests in Thailand and that the threat to tourists was not serious. Cooke pointed out that the protests were largely carried out in a festive, non-hostile fashion in keeping with the Thai people's famous warmth and hospitality. Cooke also claims that tourism in Thailand took just three months to bounce back from a short lived set back in the wake of the protests and is now looking healthier than ever. "Tourism bounced straight ...

Scientists have discovered a new component of mitochondria that plays a key part in their function. The discovery, which is presented in the journal Cell Metabolism, is of potential significance to our understanding of both inherited and age-related diseases. Mitochondria are normally called the cell's power plants since they convert the energy in our food into a form that the body can use. To work properly, the mitochondria have to form new proteins, which they do in their ribosomes. A group of researchers at Karolinska Institutet in Sweden and the Max Planck Institute ...
