For decades, the composition of the oral health care workforce in the ...

CINCINNATI—Health care practitioners have long understood the importance of "door to balloon" time for heart attack patients—the faster they can get the patient from the door of the hospital to a catheterization lab to open a clogged artery, the better the patient will do. But a University of Cincinnati (UC) emergency medicine researcher says it's also important to study the "medical contact to balloon" time, acknowledging the role that emergency medical services (EMS) responders play in speeding patient care. In a paper published online in the journal Academic Emergency ...

Washington, D.C.—On March 17, the tiny MESSENGER spacecraft completed its primary mission to orbit and observe the planet Mercury for one Earth-year. The bounty of surprises from the mission has completely altered our understanding of the solar system's innermost planet. As reported in one of two papers published today on Science Express, scientists have found that Mercury's core, already suspected to occupy a greater fraction of the planet's interior than do the cores of Earth, Venus, or Mars, is even larger than anticipated. The companion paper shows that the elevation ...

Physicists who have studied the mixing between two incompatible fluids have found that it is possible to control the undercurrents of one circulating fluid to optimise its exposure to the other. This work, which is about to be published in EPJ E¹, was performed by Jorge Peixinho from CNRS at Le Havre University, France, and his colleagues from the Benjamin Levich Institute, City University of New York, USA. The authors compared quantitative experimental observations of a viscous fluid, similar to honey, with numerical simulations. They focused on a fluid, which partially ...

URBANA – University of Illinois research reports that swine producers can feed distiller's dried grain with solubles (DDGS) to their pigs without concern for sulfur content. "When you buy DDGS, you don't have to be concerned about the level of sulfur it contains because there doesn't appear to be any impact on pig performance," said U of I animal sciences professor Hans Stein. According to the researcher, DDGS, a co-product of the ethanol industry, is used as a feed ingredient in diets fed to swine. To maintain a stable pH in fermentation vats, ethanol producers ...

The Defense Department, faced with cuts of what Secretary Leon Panetta said could be $487 billion over the next ten years, can find tens of billions of dollars in cost reductions by better aligning the Pentagon supply chain rather than imposing precipitous reductions to the uniformed forces, according to a former Army colonel who is speaking at a conference hosted by the Institute for Operations Research and the Management Sciences (INFORMS®), the premier organization for advanced analytics professionals. The INFORMS Military Applications Society Conference takes place ...

Amsterdam, NL, 21 March, 2012 – Fertility problems, recurrent miscarriages, and pregnancy complications can occur when maternal immunological tolerance of the fetus is impaired. Gérard Chaouat and colleagues from Inserm et Assistance Publique et Université Paris Sud Orsay, Hopital Antoine Bèclère, Clamart Cedex, France (now in Hopital Saint Louis, Paris), trace the evolution of the science of reproductive immunology to show how the current understanding of maternal-fetal tolerance/dialogue has developed, and its implications for the treatment of infertility disorders. ...

Remember Slinky®, the coiled metal spring that "walks" down stairs with just a push, momentum and gravity? Researchers at the National Institute of Standards and Technology (NIST) have developed their own version of this classic—albeit 10 million times smaller—as a novel technology for manipulating and measuring DNA molecules and other nanoscale (billionth of a meter) materials. In the first of two recent papers,* Samuel Stavis, Elizabeth Strychalski and colleagues demonstrated that a nanoscale fluidic channel shaped like a staircase with many steps (developed previously ...

Could widespread conjugal visitation reduce sexual offending in prisons? It's a possibility, according to Stewart D'Alessio and his team from Florida International University in the US. Their work shows that in states where conjugal visits are permitted, there are significantly fewer instances of reported rape and other sexual offenses in their prisons. The study is published online in Springer's American Journal of Criminal Justice. At present, there are two opposing theories of the causes of sexual violence. The feminist perspective asserts that sexual violence is motivated ...

CORAL GABLES, FL (March 21, 2012)—A team of researchers led by Michael H. Antoni, director of the Center for Psycho-Oncology Research at the University of Miami (UM) has shown that a stress management program tailored to women with breast cancer can alter tumor-promoting processes at the molecular level. The new study recently published in the journal Biological Psychiatry is one of the first to link psychological intervention with genetic expression in cancer patients. According to the study, the group-based Cognitive-Behavioral Stress Management (CBSM) intervention ...

According to Cardinal Web Solutions, an Internet marketing firm in Atlanta, all business pages on Facebook will be converted to the Timeline format on March 30th 2012. While this may be the biggest change from a visual standpoint, the changes to features and the heretofore virtually unlimited versatility that has made Facebook an essential social media marketing tool will be a hard pill to swallow for many businesses. Communications sent thru Facebook by businesses are being throttled to 16% per month of current Facebook fans that have "liked" your page. This ...

It turns out you can be too thin—especially if you're a nanoscale battery. Researchers from the National Institute of Standards and Technology (NIST), the University of Maryland, College Park, and Sandia National Laboratories built a series of nanowire batteries to demonstrate that the thickness of the electrolyte layer can dramatically affect the performance of the battery, effectively setting a lower limit to the size of the tiny power sources.* The results are important because battery size and performance are key to the development of autonomous MEMS—microelectromechanical ...

NEW YORK – March 21, 2012 – Research by Columbia Business School's Modupe Akinola, Assistant Professor, Management, and Wendy Berry Mendes, Associate Professor, Sarlo/Ekman Endowed Chair of Emotion, University of California San Francisco in Behavioral Neuroscience examines how increases in cortisol, brought on by an acute social stressor, can influence threat-related decision making. The researchers studied a group of police officers completing a standardized laboratory stressor and then afterwards the group completed a computer simulated threat-related decision making ...

Wilmington, DE— A team of researchers led by A. K. Rajasekaran, PhD, Director of the Nemours Center for Childhood Cancer Research, has shown that a key protein involved in cell function and regulation is stopped by a substance present in cigarette smoke. Their work is published online in the American Journal of Physiology - Lung Cell and Molecular Physiology. Cigarette smoke is well recognized as a cause of lung cancer and is associated with many other forms of cancer in adults. Cigarette smoke has more than 4,000 components, many of which are linked to the development ...

(Santa Barbara, Calif.) ––Thanks to the MESSENGER spacecraft, and a mission that took more than 10 years to complete, scientists now have a good picture of the solar system's innermost planet. On March 17, MESSENGER (MErcury Surface, Space Environment, GEochemistry, and Ranging) completed its one-year primary mission, orbiting Mercury, capturing nearly 100,000 images, and recording data that reveals new information about the planet's core, topography, and the mysterious radar bright material in the permanently shadowed areas near the poles. The findings are presented ...

"Business owners are being squeezed from all angles. Rising gas prices, increased regulations and unemployment all affect the bottom line. When no one is hiring, more people begin starting their own businesses or become consultants. Basically, you have more people trying to get less business. And that means there's more competition. But there is one thing you can do to get a head start on your competition, and that's through innovation. "Innovation isn't just about creating new products", says Julie Austin, whose company Creative Innovation, teaches businesses ...

STANFORD, Calif. — Scientists at the Stanford University School of Medicine have shown for the first time how brain function differs in people who have math anxiety from those who don't. A series of scans conducted while second- and third-grade students did addition and subtraction revealed that those who feel panicky about doing math had increased activity in brain regions associated with fear, which caused decreased activity in parts of the brain involved in problem-solving. "The same part of the brain that responds to fearful situations, such as seeing a spider or ...

Why does inhaling anesthetics cause unconsciousness? New insights into this century-and-a-half-old question may spring from research performed at the National Institute of Standards and Technology (NIST).* Scientists from NIST and the National Institutes of Health have found hints that anesthesia may affect the organization of fat molecules, or lipids, in a cell's outer membrane—potentially altering the ability to send signals along nerve cell membranes. "A better fundamental understanding of inhaled anesthetics could allow us to design better ones with fewer side effects," ...

The alphabet of data processing could include more elements than the "0" and "1" in future. An international research team has achieved a new kind of bit with single electrons, called quantum bits, or qubits. With them, considerably more than two states can be defined. So far, quantum bits have only existed in relatively large vacuum chambers. The team has now generated them in semiconductors. They have put an effect in practice, which the RUB physicist Prof. Dr. Andreas Wieck had already theoretically predicted 22 years ago. This represents another step along the path ...

A new assessment of wind energy in India by Lawrence Berkeley National Laboratory has found that the potential for on-shore wind energy deployment is far higher than the official estimates— about 20 times and up to 30 times greater than the current government estimate of 102 gigawatts. This landmark finding may have significant impact on India's renewable energy strategy as it attempts to cope with a massive and chronic shortage of electricity. "The main importance of this study, why it's groundbreaking, is that wind is one of the most cost-effective and mature renewable ...

The first day of spring brought record high temperatures across the northern part of the United States, while much of the Southwest was digging out from a record-breaking spring snowstorm. The weather, it seems, has gone topsy-turvy. Are the phenomena related? Are climate changes in one part of the world felt half a world away? To understand the present, scientists look for ways to unlock information about past climate hidden in the fossil record. A team of scientists led by Syracuse University geochemist Zunli Lu has found a new key in the form of ikaite, a rare mineral ...

Spanish and Danish researchers have developed a method for the in vivo study of the unknown metabolism of selenium, an essential element for living beings. The technique can help clarify whether or not it possesses the anti-tumour properties that have been attributed to it and yet have not been verified through clinical trials. "It is vox populi that doctors around the world recommend selenium supplements to complement traditional therapy against cancer and the AIDS virus but the truth is that the basics of these properties are not clear," explains to SINC Justo Giner, ...
