MATERIALS – Transparent performance . . . Windshields, windows, solar panels, eyeglasses, heart stents and hundreds of other products representing a multi-billion-dollar market are potential targets for Oak Ridge National Laboratory's thin-film superhydrophobic technology. Conventional commercially available products tend to lack transparency, suitable bonding capability or both, making them largely impractical, said Tolga Aytug, one of the developers. The ORNL product, based on glass, can be produced with manufacturing processes that are cost effective and easily scaled ...

DURHAM, N.C. -- Treating adolescents for major depression can also reduce their chances of abusing drugs later on, a secondary benefit found in a five-year study of nearly 200 youths at 11 sites across the United States. Only 10 percent of 192 adolescents whose depression receded after 12 weeks of treatment later abused drugs, compared to 25 percent of those for whom treatment did not work, according to research led by John Curry, a professor of psychology and neuroscience at Duke University. "It turned out that whatever they responded to -- cognitive behavioral therapy, ...

Reston, Va. (June 4, 2012) – For those with esophageal cancer, initial staging of the disease is of particular importance as it determines whether to opt for a curative treatment or palliative treatment. Research presented in the June issue of The Journal of Nuclear Medicine shows that physicians using positron emission tomography (PET)/computed tomography (CT) can discern incremental staging information about the cancer, which can significantly impact management plans. In 2012, an estimated 17,500 people will be diagnosed with esophageal cancer and 15,000 will die from ...

Researchers at the University of Toronto Scarborough (UTSC) used an innovative technique to examine chemical interactions that are implicated in Parkinson's Disease. The work details how a protein called alpha-synuclein interacting with the brain chemical dopamine can lead to protein misfolding and neuronal death. Parkinson's Disease is a neurodegenerative disease which results in loss of motor control and cognitive function. Although the cause isn't known precisely, the disease involves the death of brain cells that produce dopamine, a chemical important in neuronal ...

Tampa, Fla. (June 4, 2012) – After carrying out a study comparing the repopulation efficiency of immature hepatic stem/progenitor cells and mature hepatocytes transplanted into liver-injured rats, a research team from Sapporo, Japan concluded that mature hepatocytes offered better repopulation efficiency than stem/progenitor cells. Until day 14 post-transplantation, the growth of the stem/progenitor cells was faster than the mature hepatocytes, but after two weeks most of the stem/progenitor cells had died. However, the mature hepatocytes continued to survive and proliferate ...

Tampa, Fla. (June 4, 2012) – When autologous (self-donated) lung-derived mensenchymal stem cells (LMSCs) were transplanted endoscopically into 13 adult female sheep modeled with emphysema, post-transplant evaluation showed evidence of tissue regeneration with increased blood perfusion and extra cellular matrix content. Researchers concluded that their approach could represent a practical alternative to conventional stem cell-based therapy for treating emphysema. The study is published in Cell Transplantation (21:1), now freely available on-line at http://www.ingentaconnect.com/content/cog/ct/. ...

The mosquito is possibly summer's biggest nuisance. Sprays, pesticides, citronella candles, bug zappers — nothing seems to totally deter the blood-sucking insect. And neither can rain apparently. Even though a single raindrop can weigh 50 times more than a mosquito, the insect is still able to fly through a downpour. Georgia Tech researchers used high-speed videography to determine how this is possible. They found the mosquito's strong exoskeleton and low mass render it impervious to falling raindrops. The research team, led by Assistant Professor of Mechanical Engineering ...

WEST LAFAYETTE, Ind. - A new Purdue University-developed process for creating biofuels has shown potential to be cost-effective for production scale, opening the door for moving beyond the laboratory setting. A Purdue economic analysis shows that the cost of the thermo-chemical H2Bioil method is competitive when crude oil is about $100 per barrel when using certain energy methods to create hydrogen needed for the process. If a federal carbon tax were implemented, the biofuel would become even more economical. H2Bioil is created when biomass, such as switchgrass or corn ...

As voters increasingly rely on websites of presidential primary candidates for news, they run a risk because candidates' online attacks are not vetted through traditional "watchdog journalists" and other gatekeepers to determine accuracy or fairness, according to a study by Baylor University researchers. "The primary danger is that constituents often use this one-sided information to decide how to vote," said Mia Moody, Ph.D., study co-author and an assistant professor of journalism, public relations and new media in Baylor's College of Arts & Sciences. The study — "Not ...

Click here for more information. Drugs for type 2 diabetes can contribute to weight gain, bone fractures and cardiovascular problems, but in mice, an investigational drug appears to improve insulin sensitivity without those troublesome side effects, researchers at Washington University ...

Over the weekend of June 2 and 3, Typhoon Mawar skirted the east coast of the Philippines bringing heavy surf, heavy rainfall and gusty winds that led to several missing and injured people. NASA's TRMM satellite and Aqua satellite showed heavy rainfall and cloud extent of the storm. On June 1, Mawar (known as Ambo in the Philippines) had maximum sustained winds near 45 knots and it was about 245 miles east-northeast of Manila, Philippines. On that day, as Mawar continued north, some warnings were posted for the Philippines: Public storm warning signal #1 was up in the ...

ANN ARBOR, Mich.—Religious practices that strongly control female sexuality are more successful at promoting certainty about paternity, according to a study published in the current issue of the Proceedings of the National Academy of Sciences. The study analyzed genetic data on 1,706 father-son pairs in a traditional African population—the Dogon people of Mali, West Africa—in which Islam, two types of Christianity, and an indigenous, monotheistic religion are practiced in the same families and villages. "We found that the indigenous religion allows males to achieve ...

DALLAS – June 4, 2012 – UT Southwestern Medical Center researchers have taken a major step toward understanding the cellular clock, mapping for the first time the atomic-level architecture of a key component of the timekeeper that governs the body's daily rhythms. The daily, or circadian, cycles guided by the body's clocks affect our ability to get a good night's sleep, how fast we recover from jet lag, and even the best time to give cancer treatments, said Dr. Joseph Takahashi, senior author of the Science study published online and a pioneer in the study of circadian ...

The RHESSI (Ramaty High Energy Solar Spectroscopic Imager) satellite focuses on the highest energy x-rays and gamma-rays produced by the sun, helping to observe solar flares of all shapes and sizes. The satellite is pointed toward the sun, and constantly in rotation, which provides a serendipitous bit of side research: by monitoring the limb of the sun on its four second rotation cycle, RHESSI's Solar Aspect System (SAS) has produced ten years worth of precise measurements of the sun's diameter. This has already provided scientists with one of the most accurate measurements ...

When Venus transits the sun on June 5th and 6th, an armada of spacecraft and ground-based telescopes will be on the lookout for something elusive and, until recently, unexpected: The Arc of Venus. "I was flabbergasted when I first saw it during the 2004 transit," recalls astronomy professor Jay Pasachoff of Williams College. "A bright, glowing rim appeared around the edge of Venus soon after it began to move into the sun." For a brief instant, the planet had turned into a "ring of fire." Researchers now understand what happened. Backlit by the sun, Venus's atmosphere ...

Half of adults over age 65 made at least one emergency department (ED) visit in the last month of life, in a study led by a physician at the San Francisco VA Medical Center (SFVAMC) and UCSF. Three quarters of ED visits led to hospital admissions, and more than two-thirds of those admitted to the hospital died there. In contrast, the 10 percent of study subjects who had enrolled in hospice care at least one month before death were much less likely to have made an ED visit or died in the hospital. "For too many older Americans, the emergency department is a conduit ...

COLUMBUS, Ohio - Scientists have designed a screening tool that provides a fast, easy and relatively inexpensive way to predict levels of a specific toxin in lakes that are prone to blue-green algal blooms. Blue-green algae is not your average pond scum - rather than consisting of plant-like organisms, blue-green algae actually are cyanobacteria, and some species are linked to the production and release of the toxin microcystin into the water. Human exposure to the toxin through drinking or recreational water contact can threaten public health by causing liver damage, ...

OAK BROOK, Ill. – Researchers studying stroke patients have found a strong association between impairments in a network of the brain involved in emotional regulation and the severity of post-stroke depression. Results of the study are published online in the journal Radiology. "A third of patients surviving a stroke experience post-stroke depression (PSD)," said lead researcher Igor Sibon, M.D., Ph.D., professor of neurology at the University of Bordeaux in Bordeaux, France. "However, studies have failed to identify a link between lesions in the brain caused by ischemia ...

San Diego, CA, June 5, 2012 – It's estimated that almost 23% of women enter pregnancy as smokers and more than half continue to smoke during pregnancy, leading to excess healthcare costs at delivery and beyond. In one of the first studies to assess smoking bans and taxes on cigarettes, along with the level of tobacco control spending, researchers have found that state tobacco control policies can be effective in curbing smoking during pregnancy, and in preventing a return to smoking within four months on average, after delivery. The results were published online today ...

During a recent segment on FOX 29, personal injury attorney Dean Weitzman of MyPhillyLawyer discussed how reckless bus drivers put countless lives in danger by ignoring traffic signals throughout Philadelphia. "Drivers need to understand and really appreciate that they have 50 souls in their hands every trip they take," commented Weitzman. That number doesn't include other drivers and their passengers, pedestrians and cyclists who share the Philly roadways with SEPTA buses, SEPTA tandem buses, tour buses and trolley buses. SEPTA buses range from 40 to 60 feet ...

San Antonio, Texas, June 5, 2012 – Three patients with chronic kidney failure treated at a dialysis center in Los Angeles County, California contracted a bacterial infection in the blood (sepsis) caused by improper cleaning and disinfection of a reusable medical device called a dialyzer – an artificial kidney. Described in a poster presented at the 39th Annual Educational Conference and International Meeting of the Association for Professionals in Infection Control and Epidemiology (APIC), the County of Los Angeles Department of Public Health, conducted an investigation ...

San Antonio, Texas, June 5, 2012 – The introduction of daily bathing with disposable, germ-killing cloths resulted in a sustained, significant decrease in methicillin-resistant Staphylococcus aureus (MRSA) incidence at a Canadian geriatric facility, according to a poster presented at the 39th Annual Educational Conference and International Meeting of the Association for Professionals in Infection Control and Epidemiology (APIC).
