A pile of dirty dishes looms in the kitchen. It's your spouse's night to wash, but you know he or she has had a long day so you grab a sponge and step up to the plate. It's just one of the minor daily sacrifices you make in the name of love. But what if you had a long, stressful day, too? A new study from the University of Arizona, forthcoming in the Journal of Social and Personal Relationships, published by SAGE, suggests that while making sacrifices in a romantic relationship is generally a positive thing, doing so on days when you are feeling especially stressed may ...

Experiencing connections, regularities, and coherence in their environment may lead people to feel a greater sense of meaning in life, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. The research, conducted by graduate student Samantha Heintzelman of the University of Missouri, along with advisor Laura King and fellow graduate student Jason Trent, suggests that meaning in life has an important adaptive function, connecting people to the world that surrounds them and, thereby, boosting their chances of ...

Infrared data indicates temperatures of cloud tops and the surface of the sea beneath tropical cyclones, and NASA's AIRS instrument captured an infrared look at low pressure area System 92P in the Southwestern Pacific Ocean that hinted it was rapidly developing into Tropical Cyclone Zane. Zane is expected to make landfall in northeastern Queensland on May 1 at cyclone strength. The infrared image of System 92P was taken from the Atmospheric Infrared Sounder (AIRS) instrument aboard NASA's Aqua satellite on April 29 at 1505 UTC (11:05 a.m. EDT). The AIRS data showed that ...

Even as the snow begins to retreat in the eastern part of Russia, fires are being set to clear the land for planting. This Moderate Resolution Imaging Spectroradiometer (MODIS) image from the Aqua satellite was captured on April 29, 2013. MODIS shows the fires as red dots on this image and also visible are smoke plumes rising from the fires which are most likely the result of growing-season activities for farmer in the region. Fire is still used in many parts of the world fire as a resource management tool, clearing land for planting, renewing pastures, and returning ...

In Western Australia, the wet season occurs between December and March and the dry season between May and October. The reversals of prevailing winds in the two season drives the shift from wet to dry and back. In April and May, fires usually burn themselves out within a few days due to the fact that even though there are dry spots that may catch fire, the wet area around them will keep the fires from burning out of control. The worst time for fire is late in the dry season, when vegetation has dried to tinder and blazes tend to be uncontrollable, intense, and dangerous. The ...

Uncertainty issues are paramount in the assessment of risks posed by natural hazards and in developing strategies to alleviate their consequences. In a paper published last month in the SIAM/ASA Journal on Uncertainty Quantification, the father-son team of Jerome and Seth Stein describe a model that estimates the balance between costs and benefits of mitigation—efforts to reduce losses by taking action now to reduce consequences later— following natural disasters, as well as rebuilding defenses in their aftermath. Using the 2011 Tohoku earthquake in Japan as an example, ...

DURHAM, N.C. -- A protein produced by mast cells in the immune system may predict which people infected with dengue virus will develop life-threatening complications, according to researchers at Duke Medicine and Duke-National University of Singapore (Duke-NUS). Their study also found that in experiments in mice, a class of drugs commonly used to treat asthma by targeting the mast cells could help treat vascular symptoms associated with dengue infections. The findings were published in the online journal eLife on April 30, 2013. Dengue virus is spread by mosquitoes ...

Many of the genes regulating the inflammation and immune response of the body are also associated with low HDL-cholesterol levels in the circulation, tells the recent study conducted at the University of Helsinki, Finland. The research also discovered that the quality of HDL particle can vary considerably. Cholesterol is a major risk factor for heart disease. Elevated LDL-cholesterol, commonly known as the 'bad cholesterol,' is associated with increased risk of heart disease while HDL-cholesterol, the 'good cholesterol', is associated with decreased risk. During ...

COLLEGE STATION – According to the Centers for Disease Control, about one in six Americans gets food poisoning each year. Additionally, virus infection risks from consumption of raw oysters in the U.S. are estimated to cost around $200 million a year. To address the issue of health risk from eating raw oysters, Texas A&M University graduate student Chandni Praveen, along with Texas A&M AgriLife Research scientist Dr. Suresh Pillai and a team of researchers from other agencies and institutions, studied how electron-beam pasteurization of raw oysters may reduce the possibility ...

A properly functioning immune system is a lesson in balance, providing protection against disease without attacking healthy tissue. Work led by St. Jude Children's Research Hospital scientists and published recently in Nature Immunology has identified a mechanism that helps T cells find that sweet spot where the strength of the immune response matches the threat. The finding offers important insight into the immune response. The work also lays the foundation for advancing understanding and treatment of problems that arise when the system malfunctions, including autoimmune ...

Ann Arbor, Mich. — Federal funding for health care coverage of children with diabetes varies significantly from state to state across the United States, according to new research from the University of Michigan. The new research, published earlier this year in the Journal of Pediatrics, examines a public program for children with chronic diseases called the Children with Special Health Care Needs program, which is funded through Title V of the Social Security Act of 1935, and provides federal support and serves as a safety net for children with chronic diseases. In ...

SAN FRANCISCO, April 30, 2013 – The American Educational Research Association (AERA) today issued a new report titled Prevention of Bullying in Schools, Colleges, and Universities: Research Report and Recommendations. The report results from the work of a blue-ribbon AERA task force mandated to prepare and present practical short-term and long-term recommendations to address bullying of children and youth. The report's release coincides with the association's 94th Annual Meeting in San Francisco, where more than 15,000 education researchers are gathered to discuss research ...

The world population could top 8 billion in the year 2023 if current growth rates remain constant, according to United Nations figures. However, if global fertility rates slow more quickly than expected, there could be up to half a billion fewer mouths to feed on Earth in 2023. Based on a recent study by a University of Missouri anthropologist, economic changes have the greatest impact on reducing family size, and thus slowing population growth, compared to other factors. Understanding the causes of declining birth rates may lead to improved policies designed to influence ...

A UCLA-led study of adolescents receiving treatment for methamphetamine dependence has found that girls are more likely to continue using the drug during treatment than boys, suggesting that new approaches are needed for treating meth abuse among teen girls. Results from the study, conducted by the UCLA Center for Behavioral and Addiction Medicine and the community-based substance abuse treatment program Behavioral Health Services Inc., are published in the April edition of the Journal of Adolescent Health. "The greater severity of methamphetamine problems in adolescent ...

WASHINGTON – The number of private and public entities conducting research in synthetic biology worldwide grew significantly between 2009 and 2013, according to the latest version of an interactive map produced by the Synthetic Biology Project at the Woodrow Wilson International Center for Scholars. The map is available online at http://www.synbioproject.org/map. Synthetic biology, an area of research focused on the design and construction of new biological parts and devices, or the re-design of existing biological systems, is an emerging field and the focus of labs and ...

Efforts to lower health care costs in the United States have focused at times on demands to reform the medical malpractice system, with some researchers asserting that large, headline-grabbing and "frivolous" payouts are among the heaviest drains on health care resources. But a new review of malpractice claims by Johns Hopkins researchers suggests such assertions are wrong. In their review of malpractice payouts over $1 million, the researchers say those payments added up to roughly $1.4 billion a year, making up far less than 1 percent of national medical expenditures ...

COLUMBIA, Mo. – One of 100,000 children is born with Menkes disease, a genetic disorder that affects the body's ability to properly absorb copper from food and leads to neurodegeneration, seizures, impaired movement, stunted growth and, often, death before age 3. Now, a team of biochemistry researchers at the University of Missouri has published conclusive scientific evidence that the gene ATP7A is essential for the dietary absorption of the nutrient copper. Their work with laboratory mice also provides a greater understanding of how this gene impacts Menkes disease as ...

The mantra that quality is more important than quantity is true when considering how social relationships influence depression, say U-M researchers in a new study. After analyzing data from nearly 5,000 American adults, the researchers found that the quality of a person's relationships with a spouse, family and friends predicted the likelihood of major depression disorder in the future, regardless of how frequently their social interactions took place. Individuals with strained and unsupportive spouses were significantly more likely to develop depression, whereas ...

BOSTON—A type of low-grade but sometimes lethal brain tumor in children has been found in many cases to contain an unusual mutation that may help to classify, diagnose and guide the treatment of the tumors, report scientists at Dana-Farber Cancer Institute. The researchers led a study of pediatric low-grade gliomas, samples of which were collected through an international consortium organized by brain tumor specialists at Dana-Farber/Children's Hospital Cancer Center. Their findings are being published online by the Proceedings of the National Academy of Sciences (PNAS) ...

In 2012, more than 3 million people had stents inserted in their coronary arteries. These tiny mesh tubes prop open blood vessels healing from procedures like a balloon angioplasty, which widens arteries blocked by clots or plaque deposits. After about six months, most damaged arteries are healed and stay open on their own. The stent, however, is there for a lifetime. Most of the time, that's not a problem, says Patrick Bowen, a doctoral student studying materials science and engineering at Michigan Technological University. The arterial wall heals in around the old stent ...

Vitamin D is crucial to the growth of healthy bones. It is especially important that babies get enough of it during the first twelve months of their lives when their bones are growing rapidly. This is why health care providers frequently recommend that parents give their babies a daily vitamin D supplement. But how much vitamin D should babies be given? A new study led by Prof. Hope Weiler, from the School of Dietetics and Human Nutrition at McGill University and by Dr. Celia Rodd of McGill's Department of Pediatrics, has just confirmed that 400 IU of vitamin D daily ...

(Boston) – Results of a pilot study suggest that a virtual patient advocate (VPA) could help influence positive changes and help women have healthier pregnancies. Developed at Boston University School of Medicine (BUSM), Boston Medical Center (BMC) and Northeastern University, "Gabby" is an innovative tool developed to deliver preconception care (PCC) to African-American women through interactive conversations online. The study results, which are published online in the American Journal of Health Promotion, suggest that Gabby could help identify risk factors and influence ...

Durham, NC — A tiny bird fossil discovered in Wyoming offers clues to the precursors of swift and hummingbird wings. The fossil is unusual in having exceptionally well-preserved feathers, which allowed the researchers to reconstruct the size and shape of the bird's wings in ways not possible with bones alone. Researchers spotted the specimen — the nearly complete skeleton of a bird that would have fit in the palm of your hand and weighed less than an ounce — while working at the Field Museum of Natural History in Chicago. The newly discovered bird was named Eocypselus ...

Just as people have embraced computers and smart phones, they may also give their blessing to talking tissue boxes and other smart objects, according to Penn State researchers. "Smart objects will become more and more a part of our daily lives," said S. Shyam Sundar, Distinguished Professor of Communications and co-director of the Media Effects Research Laboratory. "We believe the next phase is that objects will start talking and interacting with humans, and our goal is to figure out the best ways for objects to communicate with humans." As sensors and computers increasingly ...
