TALLAHASSEE, Fla. &#9135 The heat generated by everyday energy consumption in metropolitan areas is significant enough to influence the character of major atmospheric circulation systems, including the jet stream during winter months, and cause continental-scale surface warming in high latitudes, according to a trio of climate researchers that includes Ming Cai, a professor in Florida State University's Department of Meteorology. Led by Guang Zhang, a research meteorologist at Scripps Institution of Oceanography at the University of California, San Diego, the scientists ...

Research conducted by Matthew Shaffer, a doctoral psychology student at UT and C. Veronica Smith, an assistant psychology professor at the University of Mississippi, reveals that the first sexual experience can set the tone for the rest of one's sexual life. The study is published in the Journal of Sex and Marital Therapy and is the first to look at whether the circumstances of losing one's virginity have lasting consequences. "The loss of virginity is often viewed as an important milestone in human development, signifying a transition to adulthood," said Shaffer. ...

The majority of Americans support a broad array of policies to reduce gun violence, according to a new national public opinion survey conducted by researchers at the Johns Hopkins Bloomberg School of Public Health. These policies include: requiring universal background checks for all gun sales (supported by 89 percent); banning the sale of military-style semiautomatic assault weapons (69 percent); banning the sale of large-capacity ammunition magazines (68 percent); and prohibiting high-risk individuals from having guns, including those convicted of a serious crime as a ...

PHILADELPHIA—A mailing or phone call to help patients get screened for colorectal cancer significantly increases their chances of actually getting tested, according to a study published in the January issue of Cancer Epidemiology, Biomarkers and Prevention by researchers at the Kimmel Cancer Center at Jefferson. The research team, led by Ronald E. Myers, Ph.D., Professor and Director of Division of Population Science, Department of Medical Oncology at Thomas Jefferson University, performed a randomized, controlled trial of 945 people aged 50-79 to test the impact of a ...

Stanford Engineering's Center for Turbulence Research (CTR) has set a new record in computational science by successfully using a supercomputer with more than one million computing cores to solve a complex fluid dynamics problem—the prediction of noise generated by a supersonic jet engine. Joseph Nichols, a research associate in the center, worked on the newly installed Sequoia IBM Bluegene/Q system at Lawrence Livermore National Laboratories (LLNL) funded by the Advanced Simulation and Computing (ASC) Program of the National Nuclear Security Administration (NNSA). Sequoia ...

"We see functional stupidity as the absence of critical reflection. It is a state of unity and consensus that makes employees in an organisation avoid questioning decisions, structures and visions", says Mats Alvesson. "Paradoxically, this sometimes helps to raise productivity in an organisation." Together with colleague André Spicer, Mats Alvesson has written an article entitled 'A Stupidity-Based Theory of Organisations', which was recently published in the renowned Journal of Management Studies and has been featured in the Financial Times. In the article, he expounds ...

WASHINGTON, Jan. 28, 2013—A new optical prescription for automobile side-view mirrors may eliminate the dreaded "blind spot" in traffic without distorting the perceived distance of cars approaching from behind. As described in a paper published today in the Optical Society's (OSA) journal Optics Letters, objects viewed in a mirror using the new design appear larger than in traditional side-view mirrors, so it's easier to judge their following distance and speed. Today's motor vehicles in the United States use two different types of mirrors for the driver and passenger ...

'Evil' scientists, deadly viruses and terrorist plots are usually the preserve of Hollywood blockbusters. But when it comes to pandemic influenza, it is the stuff of real life. As controversy about research into the H5N1 bird flu virus continues, a new paper argues for a complete overhaul of current approaches to pandemic preparedness. To Pandemic or Not? Reconfiguring Global Responses to Influenza, by Dr Paul Forster, of the ESRC STEPS Centre, investigates the H1N1 swine flu pandemic of 2009-10 and sets out some vital lessons if we are to prepare for pandemic influenza ...

The number of people in England adding salt to food at the table fell by more than a quarter in the five years following a national campaign, according to research published in the British Journal of Nutrition. In 2003, the UK Food Standards Agency and the Department of Health launched a national salt reduction campaign to raise public awareness of the impact of salt on health and to work with the food industry to reduce the amount of salt in processed foods. Although previous research found that the national campaign led to an overall reduction in salt intake, this ...

Novel, smart materials like shape memory alloys very often display so-called glass-like magnetism. Other smart materials with similar properties include those which, when exposed to a magnetic field, change their electrical resistance, known as manganites, or change their temperature, known as magnetocaloric materials. Kaustav Mukherjee and his colleagues from the Consortium for Scientific Research Indore in India studied a key stage in the formation of such a magnetic glass material, called Pr0.5 Ca0.5 Mn0.975 Al0.025 O3, in a paper about to be published in EPJ B. They ...

The electronics industry has a remarkable impact on the environment, yet research is devising new solutions to reduce it. Among these, a new compound with an unutterable name, the diisopropylammonium bromide (DIPAB), a new ferroelectric material created by an international team of researchers that include Massimo Capone and Gianluca Giovannetti of Istituto Officina dei Materiali at CNR and of the International School for Advanced Studies of Trieste (SISSA), whose research has been just published in Science magazine. "A ferroelectric material has properties analogous ...

CAMBRIDGE, MA -- Vaccines usually consist of inactivated viruses that prompt the immune system to remember the invader and launch a strong defense if it later encounters the real thing. However, this approach can be too risky with certain viruses, including HIV. In recent years, many scientists have been exploring DNA as a potential alternative vaccine. About 20 years ago, DNA coding for viral proteins was found to induce strong immune responses in rodents, but so far, tests in humans have failed to duplicate that success. In a paper appearing in the Jan. 27 online ...

COLUMBUS, Ohio – Research has suggested that compounds that give colorful fruits their rich hues, especially berries, promote health and might even prevent cancer. But for the first time, scientists have exposed extracts from numerous berries high in those pigments to human saliva to see just what kinds of health-promoting substances are likely to survive and be produced in the mouth. It's too early to name the best berry for health promotion based on this initial work. But the researchers have discovered that two families of pigments that provide berries with their colors, ...

Jena (Germany) Today, more than 500 million people are suffering from a lack of adequate protein in their diet. Each year, the number of human beings increases by 80 million, a figure which is equivalent to the present population of Germany. Thus, providing enough food, particularly sufficient protein for the increasing populace is a challenging task for societies all over the world. On a prospective basis, a progressively smaller proportion of human protein requirement can be provided by animal proteins such as meat, eggs, and milk. "However, by feeding valuable plant ...

Chapel Hill, N.C. – Biobanks are organizations that collect, store and share human specimens (e.g., blood, solid tissues, hair) for research purposes. The rise of the human genome project and of large-scale genetics studies have spurred a dramatic increase in the number of biobanks in the last decade, increasing their importance in biomedical research. But until now, biobanks in the U.S. have never been studied systematically, leaving few clear details as to how they are run or the policies and practices they use in managing their work. A new study from the University ...

Tel Aviv — Because half of all instances of hearing loss are linked to genetic mutations, advanced gene research is an invaluable tool for uncovering causes of deafness — and one of the biggest hopes for the development of new therapies. Now Prof. Karen Avraham of the Sackler Faculty of Medicine at Tel Aviv University has discovered a significant mutation in a LINC family protein — part of the cells of the inner ear — that could lead to new treatments for hearing disorders. Her team of researchers, including Dr. Henning Horn and Profs. Colin Stewart and Brian Burke of ...

This press release is available in Spanish.Poultry producers can reduce bacterial cross-contamination in poultry cages by treating the cages with forced air that's been heated to 122 degrees Fahrenheit, according to a study by U.S. Department of Agriculture (USDA) scientists. While being transported in coops on trucks, poultry that have bacteria such as Campylobacter can contaminate, through their feces, other poultry that are free of pathogens. Those disease-causing bacteria can then be passed on to the next group of birds during the next trip, and so forth, unless ...

Minimally invasive islet transplantation for patients with type 1 diabetes achieves insulin independence and reverses the progression of atherosclerosis in the first few years after transplant, according to a University of Illinois at Chicago study. The research is published in the February issue of the journal Diabetes Care and is available online. Patients with diabetes, particularly women, have a substantial increased risk of dying from ischemic heart disease, according to previous research. However, future cardiac events may be prevented with intensive glycemic ...

Irvine, Calif., Jan. 28, 2013 – Agricultural irrigation in California's Central Valley doubles the amount of water vapor pumped into the atmosphere, ratcheting up rainfall and powerful monsoons across the interior Southwest, according to a new study by UC Irvine scientists. Moisture on the vast farm fields evaporates, is blown over the Sierra Nevada and dumps 15 percent more than average summer rain in numerous other states. Runoff to the Colorado River increases by 28 percent, and the Four Corners region experiences a 56 percent boost in runoff. While the additional ...

Donors to biobanks – vast collections of human tissue samples that scientists hope will lead to new treatments for diseases – have a right to basic information about how their donations may be used, a Michigan State University ethicist argues in a new paper. The idea behind biobanks is that a repository with hundreds of thousands of samples, each linked to medical records and other health information, can yield discoveries smaller data sets can't match. Once samples are collected, researchers in many fields can use the data repeatedly. "More and larger biobanks are ...

New Rochelle, NY, January 28, 2013—Over 4 million adults in the United States identify as gay, lesbian, or bisexual and approximately 700,000 identify as transgender. An NIH-sponsored investigation by the Institute of Medicine (IOM) concluded that the health status and healthcare needs of this sizable population are poorly understood and likely inadequately met. A journal is urgently needed to support, promote, and address the unique healthcare needs of each population that comprises the LGBT community, in the United States and worldwide. LGBT Health, a new peer-reviewed ...

Chances are the only thing you remember about your first swig of alcohol is how bad the stuff tasted. What you didn't know is the person who gave you that first drink and when you had it says a lot about your predisposition to imbibe later in life. A national study by a University of Iowa-led team has found that adolescents who get their first drink from a friend are more likely to drink sooner in life, which past studies show makes them more prone to abusing alcohol when they get older. The finding is designed to help specialists predict when adolescents are likely to ...

LA JOLLA, Calif., January 27, 2013 – Most patients with an inherited heart condition known as arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) don't know they have a problem until they're in their early 20s. The lack of symptoms at younger ages makes it very difficult for researchers to study how ARVD/C evolves or to develop treatments. A new stem cell-based technology created by 2012 Nobel Prize winner Shinya Yamanaka, M.D., Ph.D., helps solve this problem. With this technology, researchers can generate heart muscle cells from a patient's own skin cells. ...

For purposes of their research, the scientists irradiated two separate layered systems with ultrashort laser pulses on the order of just one hundred femtoseconds (10-15 s). One sample consisted essentially of a single thin layer of ferromagnetic nickel. By contrast, a second sample of this same nickel material was coated with a non-magnetic layer of gold. Only a mere 30 nanometers (10-9 m) thick, the gold layer swallowed up the lion's share of the laser light so that barely any light ended up reaching the nickel layer. In spite of this, the nickel layer's magnetization ...

Charged particle accelerators have become crucially important to modern day life, be it in health care for cancer treatment or for answering important fundamental scientific questions like the existence of the HIGGS boson, the so called 'God particle'. In a simple picture, charged particles like electrons and protons are accelerated between two end plates across which an electrical voltage is applied. High energies need high voltages (millions and billions of volts) and long acceleration paths in giant sized machines – for instance the trillion volt machine called the 'large ...
