Tension is the theme running through the new consensus statement issued by the Hinxton Group, an international working group on stem cell research and regulation. Specifically, tension between intellectual property policies and scientific norms of free exchange, but also between eastern and western cultures, national and international interests, and privatized vs. nationalized health care systems. The consensus, titled Statement on Data and Materials Sharing and Intellectual Property in Pluripotent Stem Cell Science in Japan and China, was released on the Hinxton Group's ...

UNIVERSITY PARK, Pa. -- Sibling conflict represents parents' number one concern and complaint about family life, but a new prevention program -- designed and carried out by researchers at Penn State -- demonstrates that siblings of elementary-school age can learn to get along. In doing so, they can improve their future health and well-being. "Negative sibling relationships are strongly linked to aggressive, anti-social and delinquent behaviors, including substance use," said Mark Feinberg, research professor in the Prevention Research Center for the Promotion of Human ...

High-resolution real-time images show in mice how nerves may be damaged during the earliest stages of multiple sclerosis. The results suggest that the critical step happens when fibrinogen, a blood-clotting protein, leaks into the central nervous system and activates immune cells called microglia. "We have shown that fibrinogen is the trigger," said Katerina Akassoglou, Ph.D., an associate investigator at the Gladstone Institute for Neurological Disease and professor of neurology at the University of California, San Francisco, and senior author of the paper published ...

The National Science Foundation is suggesting adding a bit of spice to a geophysical scientist's research recipe of rocks, water, air, space and life: Humans. At next month's Fall Meeting of the American Geophysical Union (AGU) a behemoth of a conference of nearly 20,000 Earth and space scientists, educators, students and policy makers, an international group of scientists will make the case for adding the human element to their research. The International Network of Research in Coupled Human and Natural Systems – CHANS-Net – is supported by the National Science ...

LEXINGTON, Ky. (Nov. 27, 2012) -- Digoxin, a drug widely used to treat heart disease, increases the possibility of death when used by patients with a common heart rhythm problem − atrial fibrillation (AF), according to new study findings by University of Kentucky researchers. The results have been published in the prestigious European Heart Journal, and raises serious concerns about the expansive use of this long-standing heart medication in patients with AF. UK researchers led by Dr. Samy Claude Elayi, associate professor of medicine at UK HealthCare's Gill Heart ...

LA JOLLA, CA – November 27, 2012 – Researchers at The Scripps Research Institute (TRSI) are fueling the future of cancer treatment by improving a powerful tool in disease defense: the body's immune system. By revealing a novel but widespread cell signaling process, the scientists may have found a way to manipulate an important component of the immune system into more effectively fighting disease. The study, recently published online ahead of print by the journal Blood, shows that disabling a particular enzyme, called ItpkB, in mice improves the function of a type of immune ...

By using common materials found pretty much anywhere there is dirt, a team of Michigan State University researchers have developed a new thermoelectric material. This is important, they said, because the vast majority of heat that is generated from, for example, a car engine, is lost through the tail pipe. It's the thermoelectric material's job to take that heat and turn it into something useful, like electricity. The researchers, led by Donald Morelli, a professor of chemical engineering and materials science, developed the material based on natural minerals known ...

An enhanced approach to capturing changes on the Earth's surface via satellite could provide a more accurate account of how ice sheets, river basins and other geographic areas are changing as a result of natural and human factors. ...

Toronto, ON (27 November, 2012) -- A new method of growing cardiac tissue is teaching old stem cells new tricks. The discovery, which transforms aged stem cells into cells that function like much younger ones, may one day enable scientists to grow cardiac patches for damaged or diseased hearts from a patient's own stem cells—no matter what age the patient—while avoiding the threat of rejection. Stem cell therapies involving donated bone marrow stem cells run the risk of patient rejection in a portion of the population, argues Milica Radisic, Canada Research Chair in ...

Parents may have some new motivations to serve their kids vegetables. A new Cornell University study, published in Public Health Nutrition, found that by simply serving vegetables with dinner, the main course would taste better and the preparer was perceived to be more thoughtful and attentive. "Most parents know that vegetables are healthy, yet vegetables are served at only 23% of American dinners," said lead author Brian Wansink, PhD, the John Dyson Professor of Marketing and Consumer Behavior at Cornell University. "If parents knew that adding vegetables to the plate ...

A NASA study using TRMM satellite data revealed that the year 2010 was a particularly bad year for landslides around the world. A recent NASA study published in the October issue of the Journal of Hydrometeorology compared satellite rain data from NASA's Tropical Rainfall Measurement Mission (TRMM) to landslides in central eastern China, Central America and the Himalayan Arc, three regions with diverse climates and topography where rainfall-triggered landslides are frequent and destructive hazards to the local populations. The work, led by Dalia Kirschbaum, a research ...

It's a digital world. Or is it? NASA technologist Jonathan Pellish isn't convinced. In fact, he believes a computing technology of yesteryear could potentially revolutionize everything from autonomous rendezvous and docking to remotely correcting wavefront errors on large, deployable space telescope mirrors like those to fly on the James Webb Space Telescope. "It's fast forward to the past," Pellish said, referring to an emerging processing technology developed by a Cambridge, Mass.-based company, Analog Devices Lyric Labs. So convinced is he of its potential, Pellish ...

Tropical storm warnings are in effect in Micronesia as NASA and other satellite imagery indicates that Tropical Storm Bopha continues to intensify. The Atmospheric Infrared Sounder (AIRS) instrument that flies aboard NASA's Aqua satellite captured an infrared image of Tropical Storm Bopha on Nov. 27 at 0241 UTC that indicated a lot of power exists in the strengthening tropical storm. The AIRS image captured the eastern half of the tropical storm and showed a large area of very cold, very high cloud tops, where temperatures colder than -63 Fahrenheit (-52 Celsius) have ...

CHICAGO – New magnetic resonance imaging (MRI) research shows that mountain climbers who experience a certain type of high altitude sickness have traces of bleeding in the brain years after the initial incident, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). High altitude cerebral edema (HACE) is a severe and often fatal condition that can affect mountain climbers, hikers, skiers and travelers at high altitudes—typically above 7,000 feet, or 2,300 meters. HACE results from swelling of brain tissue due ...

CHICAGO – The role of radiologists in healthcare has long been poorly understood among the general public, but new research presented today at the annual meeting of the Radiological Society of North America (RSNA) shows that even patients who've had imaging exams in the past know little about the profession. Researchers said the study findings highlight an opportunity for radiologists to educate the public about their role in healthcare. "We know from previous studies that about half of the general public doesn't even know that radiologists are physicians," said Peter ...

CHICAGO – Visceral, or deep belly, obesity is a risk factor for bone loss and decreased bone strength in men, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). "It is important for men to be aware that excess belly fat is not only a risk factor for heart disease and diabetes, it is also a risk factor for bone loss," said Miriam Bredella, M.D., radiologist at Massachusetts General Hospital and associate professor of radiology at Harvard Medical School in Boston. According to the National Center for Health ...

CHICAGO – While obesity is considered a cardiovascular risk factor, a study presented today at the annual meeting of the Radiological Society of North America (RSNA) showed that African-American patients with coronary artery disease (CAD) have much less fat around their hearts compared to Caucasian patients. "Prior evidence suggests that increased fat around the heart may be either an independent marker of CAD burden or a predictor of the future risk of acute coronary events," said U. Joseph Schoepf, M.D., professor of radiology and medicine and director of cardiovascular ...

A peer-reviewed study of the largest number of flame retardants ever tested in homes found that most houses had levels of at least one flame retardant that exceeded a federal health guideline. The journal Environmental Science & Technology will publish the study online on November 28, 12:01am Eastern. The study led by scientists at Silent Spring Institute tested for 49 flame retardant chemicals in household dust, the main route of exposure for people and especially for children. Forty-four flame retardant chemicals were detected and 36 were found in at least 50% of the ...

In the first systemic review of evidence assessing complications following total joint arthroplasty, patients with rheumatoid arthritis (RA) were found to have an increased risk for hip dislocation after hip replacement surgery compared to those with osteoarthritis (OA). Study findings published online in Arthritis & Rheumatism, a journal of the American College of Rheumatology (ACR), also indicate that RA patients have a higher infection risk following total knee replacement than patients with OA. The ACR reports that OA—the most common form of arthritis—affects 27 ...

Imagine printing a 3-D object as easily as a typed document. Lose a button? Print one. Need a new coffee cup? Print one. While the reality of printing any object on demand may lie in the future, the technology necessary to do it has been available for decades. And soil scientists are now taking advantage of its possibilities. In a paper published online this week in the Soil Science Society of America Journal, a team of researchers headed by Philippe Baveye explored the potential of manufacturing soil science equipment using 3-D printing. They found that the technology, ...

The Threat of Sleepy Drivers in Illinois Many of us continue to do it even though we know we should not: driving when drowsy. As distracted driving becomes a major road safety concern in Illinois, so too does drowsy driving. Driving tired slows reaction time, decreases awareness and impairs judgment just like drinking and driving and distracted driving. To prevent accidents and to safeguard others on the road, drivers in Illinois should safely pull over when they become too tired to drive. According to the National Highway Traffic Safety Administration, sleepy drivers ...

More People Using Technology to Spy on Their Spouse When a couple is struggling in their marriage, tensions and suspicions often run high. As communication between the couple breaks down, some may become concerned and preoccupied with the other's activities. Consequently, as technological advances continue to be made, cases of spouses spying on one another -- either before or during divorceproceedings -- have become more common. Many people fail to realize, though, that such action can violate the law in some states, and occasionally even result in prison sentences. In ...

Retirement Accounts Play a Unique Role in Your Estate Plan Retirement is looming large -- or is already here -- for much of the U.S. population. As baby boomers continue to retire and current retirees are living longer, it is clear that retirement accounts must be considered in any estate plan. In fact, as 401(k)s and IRAs become more and more a significant part of retirees' estates, retirement accounts are proving to be the largest asset for many people. Any good estate plan must account for the tax consequences of retirement accounts. Understanding your retirement ...
