You are what you eat is truism that has been given new impetus by 'cutting edge' research led by the University of Leicester that reveals your teeth are literally shaped by your food. Indeed, evidence from teeth can be used to determine what has been eaten by an animal providing a new way of working out the diets of wild animals that doesn't involve the unpleasant task of looking at the contents of their guts. Scientists say it is also possible to use these methods to investigate diets of extinct animals such as giant marine reptiles and dinosaurs. Research led by ...

Negative thinking is a red flag for clinical depression. Stopping such thoughts early on can save millions of people from mental illness, according research study from the Frances Payne Bolton School of Nursing at Case Western Reserve University. Jaclene Zauszniewski, the Kate Hanna Harvey Professor in Community Health Nursing and associate dean for doctoral education at the school, has developed a brief 8-item survey to help healthcare providers identify depressive thinking patterns that may lead to serious depression if not identified and addressed early. Zauszniewski's ...

Soon, the gardens and fields will be blooming, fragrant and buzzing again. Bees, flies and beetles fly, as they have done for millions of years, from flower to flower in search of food or mates, drawn by flower shapes, colors and the scents of the individual plants. Often, pollinating insects favor certain scents and preferentially visit the flowers in question. Previously, researchers always assumed that floral scents and the fondness of pollinating insects for a specific scent evolved mutually via coevolution of plants and insects. However, the evolutionary biologist ...

Physicists have recently devised a new method for handling the effect of the interplay between vibrations and electrons on electronic transport. Their paper is about to be published in EPJ B¹. This study, led by scientists from Zhejiang University, Hangzhou, China, and the Centre for Computational Science and Engineering at the National University of Singapore, could have implications for quantum computers due to improvements in the transport of discrete amounts of information, known as qubits, that are encoded in electrons. The authors created an electron transport model ...

A current study shows that the risk for coronary heart disease and stroke increases by almost thirty per cent in a person whose partner has cancer. The cause is probably the negative stress to which the cancer patient's relative is exposed. We know that the relatives of chronically ill patients, especially cancer patients, have an increased risk of mental illness and depression. Previous studies have reported that mental stress and depression affect the nervous system, blood pressure and inflammation, which in turn can increase the risk of developing coronary heart disease ...

Philadelphia, PA, April 3, 2012 – Depressed individuals with a tendency to ruminate on negative thoughts, i.e. to repeatedly think about particular negative thoughts or memories, show different patterns of brain network activation compared to healthy individuals, report scientists of a new study in Biological Psychiatry. The risk for depression is increased in individuals with a tendency towards negative ruminations, but patterns of autobiographic memory also may be predictive of depression. When asked to recall specific events, some individuals have a tendency to ...

Alexandria, VA – Tornadoes are notoriously difficult to forecast, with often deadly results: In 2011, tornadoes in the U.S. killed more than 550 people, a higher death toll than in the past 10 years combined. Now a new study on short-term climate trends offers a fresh approach to tornado forecasting that may give people in tornado-prone regions more warning that twisters may soon be descending. By sorting through average atmospheric conditions in tornado-prone regions, Michael Tippet, a climate scientist at Columbia University, may have found a way to predict tornado ...

TAMPA, Fla. (April 3, 2012) – Researchers at Moffitt Cancer Center have carried out a study to validate the utility of new tumor classification systems for staging and predicting relapse-free survival for patients with neuroendocrine tumors (NETs) and who may be candidates for surgery. The results of their study were published in a recent issue of the Annals of Surgery. Neuroendocrine tumors, which form in the islet cells of the pancreas, are a relatively rare form of cancer, accounting for about 3 percent of all pancreatic malignancies. NETs that have not spread ...

People who are excluded by others online, such as on Facebook, may feel just as bad as if they had been excluded in person, according to researchers at Penn State and Misericordia University. "If you've ever felt bad about being 'ignored' on Facebook you're not alone," said Joshua Smyth, professor of biobehavioral health and of medicine at Penn State. "Facebook -- with its approximately 800 million users -- serves as a place to forge social connections; however, it is often a way to exclude others without the awkwardness of a face-to-face interaction. Most people would ...

Higher-spending hospitals do have better outcomes for their emergency patients, including fewer deaths, according to a Vanderbilt study released as a working paper through the National Bureau of Economic Research. Vanderbilt's John Graves, Ph.D., assistant professor of Preventive Medicine, along with colleagues from the Massachusetts Institute of Technology and Cornell University, examined Medicare ambulance and hospital data from 2002-2008, finding that higher-cost hospitals have significantly lower one-year mortality rates compared to lower-cost hospitals. "At ...

CHICAGO, IL – April 3, 2012 – The brains of people with anorexia and obesity are wired differently, according to new research. Neuroscientists for the first time have found that how our brains respond to food differs across a spectrum of eating behaviors – from extreme overeating to food deprivation. This study is one of several new approaches to help better understand and ultimately treat eating disorders and obesity. Eating disorders have the highest mortality rate of any mental illness. And more than two-thirds of the U.S. population are overweight or obese – a health ...

Scientists have long believed that vitamin D, which is naturally absorbed from sunlight, has an important role in the functioning of the body's autoimmune system. Now Prof. Howard Amital of Tel Aviv University's Sackler Faculty of Medicine and Sheba Medical Center has discovered that the vitamin may also affect the outcomes of patients in intensive care. In a six-month study, Prof. Amital and his colleagues found that patients who had a vitamin D deficiency lived an average of 8.9 days less than those who were found to have sufficient vitamin D. Vitamin D levels also ...

High fat diets cause damage to blood vessels earlier than previously thought, and these structural and mechanical changes may be the first step in the development of high blood pressure. These findings in mice, by Marie Billaud and colleagues from the University of Virginia School of Medicine in the US, are published online in Springer's Journal of Cardiovascular Translational Research. With age, increasing weight and metabolic disease, the internal walls of our large arteries progressively thicken and become less elastic, which can lead to furring up of the arteries ...

Children who grow up learning to speak two languages are better at switching between tasks than are children who learn to speak only one language, according to a study funded in part by the National Institutes of Health. However, the study also found that bilinguals are slower to acquire vocabulary than are monolinguals, because bilinguals must divide their time between two languages while monolinguals focus on only one. In the study, bilingual and monolingual children were asked to press a computer key as they viewed a series of images -- either of animals or of depictions ...

"Consistent brushing and flossing habits do more than just protect your oral health, they also help keep a host of other serious conditions at bay. Because of this I want to ensure that my patients fully understand ...

Montreal, April 3, 2012 — Love it or leave it — if only it were that simple. According to new research from Concordia University, the Université de Montréal and HEC Montréal, staying in an organization out of a sense of obligation or for lack of alternatives can lead to emotional exhaustion, a chronic state of physical and mental depletion resulting from continuous stress and excessive job demands. Published in the journal Human Relations, the study found that people who stay in their organizations because they feel an obligation towards their employer are more likely ...

Scientists at Dana-Farber Cancer Institute have discovered why diabetic-like symptoms develop in some patients given rapamycin, an immune-suppressant drug that also has shown anti-cancer activity and may even slow ageing. Rapamycin is widely used to prevent organ rejection and is being tested as a cancer treatment in clinical trials. About 15 percent of patients, however, develop insulin resistance and glucose intolerance after taking the drug; until now, scientists had not identified the reason. In a study published in Cell Metabolism, the researchers report that ...

Research shows iOlder adults who get infections of any kind – such as urinary, skin, or respiratory tract infections – are nearly three times more likely to be hospitalized for a dangerous blood clot in their deep veins or lungs, University of Michigan Health System research shows. The most common predictor of hospitalization for venous thromboembolism – a potentially life-threatening condition that includes both deep-vein and lung blood clots – was recent exposure to an infection, according to the study released April 3 ahead of print in Circulation. "Over half of ...

LA JOLLA, CA – April 3, 2012 ¬– A team led by scientists at The Scripps Research Institute has found antibodies that can prevent infection from widely differing strains of hepatitis C virus (HCV) in cell culture and animal models. HCV's very high rate of mutation normally helps it to evade its host's immune system. The newly discovered antibodies, however, attach to sites on the viral envelope that seldom mutate. One of the new antibodies, AR4A, shows broader HCV neutralizing activity than any previously reported anti-HCV antibody. "These antibodies attach to sites ...
