7/30/13, New Orleans, LA. Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, found that aging elicits changes in taste preferences and that such changes appear to be independent of taste nerve activity. In humans and animals aging decreases dietary and energy requirements and it is generally believed that reduced consumption is related to alterations in taste preference. However, the mechanisms underlying an age-induced shift in taste ...

7/30/13, New Orleans, LA. Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, suggests that feeding behavior and preferences may be shaped very early during development, even during fetal life. Newborns of different species react to the sweet taste demonstrating facial expressions of pleasure, such as licking (tongue protusions) and thumb sucking. These "hedonic" responses are related to brain activity in regions that respond to pleasure ...

7/30/13, New Orleans, LA. Research to be presented at the Annual Meeting of the Society for the Study of Ingestive Behavior (SSIB), the foremost society for research into all aspects of eating and drinking behavior, shows that eating a junk-food diet during pregnancy changes the development of the opioid signalling pathway in the baby's brain and permanently alters the way this system operates after birth. Opioids are chemicals which are released when we eat foods that are high in fat and sugar, and that are responsible for causing the release of another 'feel good' chemical, ...

José Domingo Villarroel, a researcher at the Teacher Training College in Bilbao (UPV/EHU-University of the Basque Country) has studied the capacity to differentiate between living and non-living beings and how this relates to environmental awareness. 118 girls and boys between the ages of 4 and 7 from public primary schools in Plentzia, Urduliz and Sopelana participated in the research and were interviewed by Villarroel himself. He himself says that the work was very laborious, "but enjoyable and what is more, the results were very striking." Each interview consisted ...

OAKLAND, Calif., July 30, 2013 — Patients with diabetes who take certain types of medications to lower their blood sugar sometimes experience severe low blood sugar levels, whether or not their diabetes is poorly or well controlled, according to a new study by Kaiser Permanente and Yale University School of Medicine. The finding, published in the current online issue of Diabetes Care, challenges the conventional wisdom that hypoglycemia is primarily a problem among diabetic patients with well-controlled diabetes (who have low average blood sugar levels). Low blood sugar ...

A JOLLA, Calif., July 30, 2013 — One major hallmark of cancer cells is their ability to survive under stressful conditions. A new study spearheaded by researchers at Sanford-Burnham Medical Research Institute reveals how a promising anticancer compound called SMIP004 specifically kills prostate cancer cells by compromising their ability to withstand environmental stress. The study, recently published in Oncotarget, uncovers novel mechanisms of anticancer activity and could lead to the development of more effective therapies for advanced and hard-to-treat forms of prostate ...

New Australian research suggests that a small dose of testosterone directed solely to the liver stimulates protein synthesis, likely preventing muscle loss and wasting, and potentially promoting muscle growth. The researchers believe they have developed a safe and effective treatment for men and women, that could prevent the muscle wasting associated with many chronic diseases and with ageing. Dr Vita Birzniece and Professor Ken Ho, from Sydney's Garvan Institute of Medical Research, showed in healthy postmenopausal women that a small dose of the male hormone testosterone ...

Whenever we have to acquire new knowledge under stress, the brain deploys unconscious rather than conscious learning processes. Neuroscientists at the Ruhr-Universität Bochum have discovered that this switch from conscious to unconscious learning systems is triggered by the intact function of mineralocorticoid receptors. These receptors are activated by hormones released in response to stress by the adrenal cortex. The team of PD Dr Lars Schwabe from the Institute of Cognitive Neuroscience, together with colleagues from the neurology department at the university clinic ...

This news release is available in German. Materials that have the ability to switch between being good conductors and being good insula-tors are considered good potential candidates for electronic building blocks – for use in transis-tors, for example. The iron oxide magnetite is the best known representative of this class of ma-terials. At low temperatures, magnetite has insulating properties; at high temperatures, the oxide is a good conductor. This switching mechanism however happens so quickly that it's been im-possible until now to fully grasp it on an atomic ...

This news release is available in German. Does psychotherapy via the Internet work? For the first time, clinical researchers from the University of Zurich have studied whether online psychotherapy and conventional face-to-face therapy are equally effective in experiments. Based on earlier studies, the Zurich team assumed that the two forms of therapy were on a par. Not only was their theory confirmed, the results for online therapy even exceeded their expectations. Six therapists treated 62 patients, the majority of whom were suffering from moderate depression. The ...

TORONTO, July 30, 2013-About nine months after suffering a stroke, the patient noticed that words written in a certain shade of blue evoked a strong feeling of disgust. Yellow was only slightly better. Raspberries, which he never used to eat very often, now tasted like blue – and blue tasted like raspberries. High-pitched brass instruments—specifically the brass theme from James Bond movies—elicited feelings of ecstasy and light blue flashes in his peripheral vision and caused large parts of his brain to light up on an MRI. Music played by a euphonium, a tenor-pitched ...

Easy access to the internet facilitates allows the daily upload of thousands of high quality insect pictures to photo sharing websites. This new phenomenon can be considered a democratic revolution in the study of biodiversity. Insect macro-photographs may be useful to illustrate online visual guides and identification keys , such as the BugGuide and Canadian Journal of Arthropod identification, or complement specialized biodiversity ...

WEST LAFAYETTE, Ind. — A new study has found that online tools, access to experimental data and other services provided through "cyberinfrastructure" are helping to accelerate progress in earthquake engineering and science. The research is affiliated with the National Science Foundation's George E. Brown Jr. Network for Earthquake Engineering Simulation (NEES), based at Purdue University. NEES includes 14 laboratories for earthquake engineering and tsunami research, tied together with cyberinfrastructure to provide information technology for the network. The cyberinfrastructure ...

If you hear an owl hooting at dusk, don't expect to catch the flute-like song of a Veery nearby. This North American thrush has probably also heard the hoots, and is singing much less to ensure that it does not become an owl's next meal. Research by Kenneth Schmidt of Texas Tech University and Kara Loeb Belinsky of Arcadia University in the US, published in Springer's journal Behavioral Ecology and Sociobiology, provides insights into just how eavesdropping between predators and prey around dusk may be shaping communication in birds. The study is the first to use the ...

July 30, 2013, Boston, Mass. -- Sun-drenched rooms make for happy residents, but large glass windows also bring higher air-conditioning bills. Now a bioinspired microfluidic circulatory system for windows developed by researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University could save energy and cut cooling costs dramatically -- while letting in just as much sunlight. The same circulatory system could also cool rooftop solar panels, allowing them to generate electricity more efficiently, the researchers report in the July 29 online ...

Washington, DC, July 30, 2013 – A moderate increase in vancomycin-resistant enterococci (VRE) at one hospital can lead to a nearly 3 percent increase in VRE in every other hospital in that county, according to a study in the August issue of the American Journal of Infection Control, the official publication of the Association for Professionals in Infection Control and Epidemiology (APIC). VRE is one of the most common bacteria that cause infections in healthcare facilities. Researchers from the Johns Hopkins Bloomberg School of Public Health, Pittsburgh Supercomputing ...

RESEARCH TRIANGLE PARK, N.C. – Taxing sugary beverages may help reduce calories, but the health benefits may be offset as consumers substitute other unhealthy foods, according to a joint study by researchers at RTI International, Duke University, and the U.S. Department of Agriculture. The study, published in the American Journal of Agricultural Economics, found that the reduction in sugary beverages due to a soda tax would likely lead consumers to substitute those calories by increasing their calorie, salt and fat intake from untaxed foods and beverages. "Instituting ...

College Park, Md. –New research out of the University of Maryland School of Public Health shows that exercise may improve cognitive function in those at risk for Alzheimer's by increasing the efficiency of brain activity associated with memory. Memory loss associated with Alzheimer's disease is one of the greatest fears among older Americans. While some memory loss is normal and to be expected as we age, a diagnosis of mild cognitive impairment, or MCI, signals more substantial memory loss and a greater risk for Alzheimer's, for which there currently is no cure. The ...

The deadly condition known as pulmonary arterial hypertension (PAH), which afflicts up to 150,000 Americans each year, may be reversible by using an inhalable gene therapy, report an international team of researchers led by investigators at the Cardiovascular Research Center at Icahn School of Medicine at Mount Sinai. In their new study, reported in the July 30 issue of the journal Circulation, scientists demonstrated that gene therapy administered through a nebulizer-like inhalation device can completely reverse PAH in rat models of the disease. In the lab, researchers ...

HOUSTON – (July 30, 2013) – New research at Rice University shows how water makes it practical to form long graphene nanoribbons less than 10 nanometers wide. And it's unlikely that many of the other labs currently trying to harness the potential of graphene, a single-atom sheet of carbon, for microelectronics would have come up with the technique the Rice researchers found while they were looking for something else. The discovery by lead author Vera Abramova and co-author Alexander Slesarev, both graduate students in the lab of Rice chemist James Tour, appears online ...

Philadelphia, Pa. -- Collaboration across surgical specialties and lessons from combat casualty care—especially the use of tourniquets and other effective strategies to control bleeding—helped mount an effective surgical response to aid victims of the Boston Marathon bombings, according to a special editorial in the July issue of The Journal of Craniofacial Surgery, which is led by Editor-in-Chief Mutaz B. Habal, MD, and published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. The experience of surgeons treating victims of the Boston bombings at Brigham ...

Researchers from the Center for Neuroprosthetics at the Swiss Federal Institute of Technology (EPFL), Switzerland, show that people can be "tricked" into feeling that an image of a human figure -- an "avatar" -- is their own body. The study is published in the open-access journal Frontiers in Behavioral Neuroscience. Twenty-two volunteers underwent a Full Body Illusion when they were stroked with a robotic device system while they watched an avatar being stroked in the same spot. The study is the first to demonstrate that Full Body Illusions can be accompanied by changes ...

(Edmonton) Family physicians regularly counsel patients about medical risks associated with heart disease, stroke, diabetes and smoking, and a team from the University of Alberta wants to add cellphone use and driving to the discussion. Talking on a cellphone while driving raises the risk of collision by four to six times—comparable to getting behind the wheel while under the influence, studies show. Addressing the problem requires educating the public about the risks, and a good place to start is in the doctor's office. "The evidence is clear and compelling. Epidemiologic, ...

New research shows a physical characterisation of the interface of the body's proteins with water. Identifying the locations where it is easiest to remove water from the interface of target proteins could constitute a novel drug design strategy. The candidate drugs would need to be engineered to bind at the site of the protein where interfacial water is most easily dislodged. These findings, based on the work of María Belén Sierra from the National University of the South, in Bahia Blanca, Argentina and colleagues, were recently published in EPJ E. The challenge is to ...
