Irvine, Calif. — UC Irvine researchers have discovered that markedly depleted amounts of an omega-3 fatty acid in brain tissue samples from Alzheimer's patients may be due to the liver's inability to produce the complex fat, also contained in fish-oil supplements. Low levels of docosahexaenoic acid, or DHA, have been associated with the chronic neurodegenerative disease affecting millions of Americans, but no cause had been identified. In postmortem liver tissue from Alzheimer's patients, the UCI team found a defect in the organ's ability to make DHA from shorter molecules ...

Ghent, 9 September 2010 – Factoring the planet's multi-trillion dollar ecosystem services into policy-making can help save cities and regional authorities money while boosting the local economy, enhancing quality of life, securing livelihoods and generating employment. This is the finding from a major international study, launched in a report by TEEB for Local and Regional Policy Makers, being released in Belgium, Brazil, India, Japan and South Africa. In the Framework of the Belgian Presidency of the European Union, the Flemish Ministry of Environment, Nature and ...

University Park, Pa. -- Repeal of birthright citizenship for the U.S.-born children of unauthorized immigrants would expand the nation's unauthorized population by at least 5 million over the next decade, according to a new report from the Migration Policy Institute. The report's principal author is Jennifer Van Hook, professor of sociology and demographics at Penn State and non-resident fellow at the Washington, D.C.-based institute. "While some are discussing an end to birthright citizenship as a means to reduce illegal immigration," Van Hook said, "repeal of birthright ...

CHAMPAIGN, Ill. — Armed with a decade's worth of satellite data, University of Illinois atmospheric scientists have documented some surprising trends in aerosol pollution concentration, distribution and composition over the Indian subcontinent. In addition to environmental impact, aerosol pollution, or tiny particles suspended in the air, can be detrimental to human health by causing a range of respiratory problems. Aerosols can come from natural sources, such as dust and pollen carried on the wind, but the most hazardous aerosols are generated by human activity – soot ...

PHILADELPHIA –- University of Pennsylvania biologists studying human reproduction have identified what is likely the major contributing factor to the maternal age-associated increase in aneuploidy, the term for an abnormal number of chromosomes during reproductive cell division. Using naturally aging mouse models, researchers showed that this basic fact of reproductive life is most likely caused by weakened chromosome cohesion. Older oocytes, or egg cells, have dramatically reduced amounts of a protein, REC8, that is essential for chromosomes to segregate correctly ...

CHAMPAIGN, Ill. — The U.S. economy is experiencing anemic growth, yet businesses are sitting on a mountain of cash worth nearly $2 trillion, according to Federal Reserve estimates. But this trend is nothing new for firms, who have been steadily increasing their cash holdings over the past three decades, a University of Illinois business professor says. Finance professor Heitor Almeida says the fact that businesses are stuffing corporate piggy banks with spare cash for the proverbial "rainy day" is unrelated to the belt-tightening brought about by the continuing financial ...

Each year in August, the aptly named town of Twinsburg, Ohio, is the site of the largest official gathering of twins in the world. Open to all multiples — identical and fraternal twins, triplets and quads from newborns to octogenarians — the weekend's events include food, live entertainment, a golf tournament, and a twins' parade. The event also has become an important site for field research by Kevin Bowyer and Patrick Flynn of the University of Notre Dame's Department of Computer Science and Engineering. Flynn has a twin sister, making this research especially relevant ...

An article just published in the scientific journal 'Osteoporosis International' introduces a validated new model that can be used to describe the current and future burden of postmenopausal osteoporosis in different national settings. The model, published by researchers from the UK on behalf of the International Osteoporosis Foundation's Committee of Scientific Advisors, was developed and validated using Swedish data. It can be used to forecast the incidence and prevalence of fractures not only by age and calendar year, but also by BMD category. It provides a high degree ...

MIAMI — September 8, 2010 -- Operational forecasting centers produce climate predictions that provide input for important decisions regarding water management, agriculture, and energy. "Assessment of Intraseasonal to Interannual Climate Prediction and Predictability", a new report from the National Research Council/National Academy of Sciences, examines current capabilities for making climate predictions -- such as seasonal hurricane or longer-term drought forecasts -- and identifies opportunities for improvement. The report finds that operational forecast centers could ...

(SACRAMENTO, Calif.) — One of the antibiotics most commonly prescribed to treat adolescent acne can increase attention spans and communication and decrease anxiety in patients with fragile X syndrome, the most common inherited cause of mental impairment, according to a new survey study that is the first published on parents' reports of their children's responses to treatment with the medication. Led by researchers at the UC Davis MIND Institute, the study examined parents' observations of their children's responses to minocycline — not the efficacy of treating patients ...

BUFFALO, N.Y. -- Treating intensive care patients who develop life-threatening bacterial infections, or septicemia, with insulin potentially could reduce their chances of succumbing to the infection, if results of a new preliminary study can be replicated in a larger study. A paper published online ahead of print in Diabetes Care reports that insulin lowered the amount of inflammation and oxidative stress in study participants who had been injected with a common bacteria, or endotoxin, known as LPS (lipopolysaccharide). The study was conducted by University at Buffalo ...

MIAMI, FL—A research team led by Cary Pirone from the Department of Biological Sciences at Florida International University has identified bilirubin in the popular Bird of Paradise plant. The breakthrough study, published in the September 2010 issue of the American Society for Horticultural Science's journal HortScience, provides new insights into color production in this iconic tropical plant. Previously thought to be an "animal-only" pigment, bilirubin is best known as the yellowish hue associated with bruises and jaundice sufferers. In 2009 the FIU researchers found ...

PASADENA, Calif.—We've all heard the predictions: e-commerce is going to be the death of traditional commerce; online shopping spells the end of the neighborhood brick-and-mortar store. While it's true that online commerce has had an impact on all types of retail stores, it's not time to bring out the wrecking ball quite yet, says a team of researchers from the California Institute of Technology (Caltech). Their investigations into how subjects assign value to consumer goods—and how those values depend on the way in which those goods are presented—are being published ...

ANN ARBOR, Mich.---In what could be a step toward higher efficiency solar cells, an international team including University of Michigan professors has invalidated the most commonly used model to explain the behavior of a unique class of materials called highly mismatched alloys. Highly mismatched alloys, which are still in the experimental stages of development, are combinations of elements that won't naturally mix together using conventional crystal growth techniques. Professor Rachel Goldman compares them to some extent to homogenized milk, in which the high-fat cream ...

St. Louis, MO, September, 8, 2010 – The government's role in improving the nation's nutrition is now firmly established with nutritional labeling for restaurant meals now mandated across the United States as part of HR 3590 Patient Protection and Affordable Health Care Act. An article in the September issue of the Journal of the American Dietetic Association explains how state and municipal labeling laws developed and how the new national law will supersede these and replace them with a uniform standard. It also addresses the American Dietetic Association's (ADA's) involvement ...

BATON ROUGE – Gregory Stone, director of LSU's WAVCIS Program and also of the Coastal Studies Institute in the university's School of the Coast & Environment, disagrees with published estimates that more than 75 percent of the oil from the Deepwater Horizon incident has disappeared. Stone recently participated in a three-hour flyover of the affected area in the Gulf, where he said that subsurface oil was easily visible from overhead. "It's most definitely there," said Stone. "It's just a matter of time before it makes itself known again." Readings from WAVCIS indicate ...

Athens, Ga. – What if there were a way to predict when a species was about to become extinct—in time to do something about it? Findings from a study by John M. Drake, associate professor in the University of Georgia Odum School of Ecology, and Blaine D. Griffen, assistant professor at the University of South Carolina, may eventually lead to such an outcome—and that is only the start. Their study also has implications for understanding drastic, even catastrophic, changes in many other kinds of complex systems, from the human brain to entire ecosystems. The paper, "Early ...

WASHINGTON—September 8, 2010—Research!America today called on Congress to take legislative action that will allow federal funding for human embryonic stem cell research to proceed, in light of U.S. District Judge Royce Lamberth's refusal yesterday to lift his recent injunction on federally funded research using embryonic stem cells. Research!America strongly supports the Stem Cell Research Advancement Act (H.R. 4808) introduced in March 2010 by Representatives Diana DeGette (D-CO) and Mike Castle (R-DE) that would allow federal funding for ethical research using human ...

In the midst of a difficult fire season in many parts of the world, the United Nations' (UN) Food and Agriculture Organization has launched a new online fire detection system that will help firefighters and natural hazards managers improve response time and resource management. The Global Fire Information Management System (GFIMS) delivers fire data from an imaging sensor aboard NASA's Terra and Aqua satellites to generate daily fire maps and images through a freely accessible Web interface. The system also dispatches detailed email alerts of the quantity and coordinates ...

A portable, laser backpack for 3D mapping has been developed at the University of California, Berkeley, where it is being hailed as a breakthrough technology capable of producing fast, automatic and realistic 3D mapping of difficult interior environments. Research leading to the development of the reconnoitering backpack, was funded by the Air Force Office of Scientific Research and the Army Research Office under the guidance of program managers, Dr. Jon Sjogren (AFOSR) and Dr. John Lavery (ARO). The backpack is the first of a series of similar systems to work without ...

If your summer travels have taken you across the Rocky Mountains, you've probably seen large swaths of reddish trees dotting otherwise green forests. While it may look like autumn has come early to the mountains, evergreen trees don't change color with the seasons. The red trees are dying, the result of attacks by mountain pine beetles. Mountain pine beetles are native to western forests, and they have evolved with the trees they infest, such as lodgepole pine and whitebark pine trees. However, in the last decade, warmer temperatures have caused pine beetle numbers to ...

The potential for outbreaks of spruce and mountain pine beetles in western North America's forests is likely to increase significantly in the coming decades, according to a study conducted by USDA Forest Service researchers and their colleagues. Their findings, published in the September issue of the journal BioScience, represent the first comprehensive synthesis of the effects of climate change on bark beetles. "Native bark beetles are responsible for the death of billions of coniferous trees across millions of acres of forests ranging from Mexico to Alaska," said Barbara ...

As interest grows in feeding distillers dried grains with solubles (DDGS) to growing pigs, many questions are being asked about the digestibility of this alternative feed option. "Previous research shows that while the amount of energy in DDGS is greater than that of corn, pigs have lower digestibility of energy in DDGS than in corn," said Hans H. Stein, U of I associate professor in the Department of Animal Sciences. "Our goal was to find out why." Stein's team wanted to develop a greater understanding of the digestibility differences between DDGS and corn. He said ...

PHILADELPHIA — Postmenopausal women diagnosed with colon cancer may be at increased risk of death if they fail to maintain a healthy body weight before cancer diagnosis, according to a study published in the September issue of Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research. The researchers found that women considered "underweight" or "obese," or who had increased abdominal obesity prior to cancer diagnosis seemed to face a greater risk of mortality. "Maintaining a healthy body weight is beneficial for postmenopausal ...

ANN ARBOR, Mich. – Chest compressions before defibrillation in patients with sudden cardiac arrest is equally successful as immediate treatment with an electrical defibrillator, according to a new study by the University of Michigan Health System. Few people who suffer cardiac arrest outside of a hospital survive. U-M physicians, along with a team of international experts, examined two promising rescue strategies: chest compressions first vs. defibrillation first. Their results, published online Thursday in BMC Journal, show that both timing strategies are effective, ...
