It is springtime and they are everywhere: Newly enamored couples walking through the city hand in hand, floating on cloud nine. Yet a few weeks later the initial rush of romance will have dissolved and the world will not appear as rosy anymore. Nevertheless, love and romance have long lasting effects. Psychologists of the German Universities of Jena and Kassel discovered that a romantic relationship can have a positive effect on personality development in young adults. Researchers report on this finding in the online edition of the renowned science magazine Journal of ...

Proteins are the workhorses of the cell and thus responsible for almost all biological functions including metabolism, signal transmission or the determination of the cell's shape. However, before they can fulfill their various tasks, the chain-like molecules must first adopt an intricate three-dimensional conformation. This process is called protein folding and is one of the most important processes in biology. In fact, in the event of improper folding, proteins are often no more able to carry out their duties, or even tend to clump together in aggregates. This in turn ...

Scientists have developed a new method for revealing how sea levels might rise around the world throughout the 21st century to address the controversial topic of whether the rate of sea level rise is currently increasing. The international team of researchers, led by the University of Southampton and including scientists from the National Oceanography Centre, the University of Western Australia, the University of South Florida, the Australian National University and the University of Seigen in Germany, analysed data from 10 long-term sea level monitoring stations located ...

The rind is the boundary layer between a cheese and its environment. It hosts a variety of microorganisms that comprise the microbiome: a symbiotic community whose members perform different tasks. Some break down proteins and fats on the rind, for example, creating volatile sulphur and ammonia compounds that are responsible for the intensive odour of some types of cheese. There are different curing methods for cheese. Some, like Limburger, Tilsiter and Appenzeller, need specific bacteria on their rinds. Others, like Camembert and Brie, develop their aroma with the assistance ...

Biomedical engineering researchers have developed an anti-cancer drug delivery method that essentially smuggles the drug into a cancer cell before triggering its release. The method can be likened to keeping a cancer-killing bomb and its detonator separate until they are inside a cancer cell, where they then combine to destroy the cell. "This is an efficient, fast-acting way of delivering drugs to cancer cells and triggering cell death," says Dr. Ran Mo, lead author of a paper on the work and a postdoctoral researcher in the joint biomedical engineering program at North ...

A new study from the University of Houston Department of Health and Human Performance (HHP) finds childhood poverty reaches into the lives of white, Hispanic and African-American young adult women, contributing to their propensity to be overweight and obese. "We know that having a low socioeconomic status during childhood contributes to children being overweight or obese," said HHP's Daphne Hernandez, who also is an executive board member of the UH Texas Obesity Research Center. "We've found a connection between the long-term exposure to poverty during childhood and ...

Amsterdam, 9 May. A study of healthy senior men has found that "relatively intensive" endurance exercise confers benefits on the heart irrespective of the age at which they began training.(1) The benefits were evident and comparable in those who had started training before the age of 30 or after the age of 40. As a result, said the investigators, 40 is not too old to start endurance training. The study, which was performed in France, was reported today at the EuroPRevent congress 2014 in Amsterdam by David Matelot, from the Inserm 1099 unit in Rennes, France. The study ...

Despite its name, the Dead Sea does support life, and not just in the sense of helping visitors float in its waters. Algae, bacteria, and fungi make up the limited number of species that can tolerate the extremely salty environment at the lowest point on Earth. Some organisms thrive in salty environments by lying dormant when salt concentrations are very high. Other organisms need salt to grow. To learn which survival strategy the filamentous fungus Eurotium rubrum uses, a team of researchers led by Eviatar Nevo from the University of Haifa in Israel, Igor Grigoriev ...

WASHINGTON, DC and NEW YORK (May 9, 2014)— An estimated 1.1 million community health center patients are left without the benefits of health coverage simply because they live in one of 24 states that have opted out of the Medicaid expansion, a key part of the Affordable Care Act (ACA), according to a new report. The research, by the Geiger Gibson/RCHN Community Health Foundation Research Collaborative at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University also shows that the vast majority (71 percent) of the 1.1 million ...

An implantable device that reduces blood pressure by sending electrical signals to the brain has been created by a group of researchers in Germany. The device has successfully reduced the blood pressure in rats by 40 per cent without any major side effects, and could offer hope for a significant proportion of patients worldwide who do not respond to existing medical treatment for the condition. The first results have been published today, 9 May, in IOP Publishing's Journal of Neural Engineering. The device consists of 24 individual electrodes that are integrated into ...

New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) indicates that brief bursts of intense exercise before meals (termed exercise 'snacking' by the study authors) helps control blood sugar in people with insulin resistance more effectively than one daily 30-minute session of moderate exercise. The research was conducted by exercise science and medicine researchers, including Monique Francois and Associate Professor James Cotter from the University of Otago, Dunedin, New Zealand. The study used a cross-over design, ...

From the age of 30 onwards, physical inactivity exerts a greater impact on a woman's lifetime risk of developing heart disease than the other well-known risk factors, suggests research published online in the British Journal of Sports Medicine. This includes overweight, the finding show, prompting the researchers to suggest that greater effort needs to be made to promote exercise. The researchers wanted to quantify the changing contribution made to a woman's likelihood of developing heart disease across her lifetime for each of the known top four risk factors in Australia: ...

Frequent arguments with partners, relatives, or neighbours may boost the risk of death from any cause in middle age, suggests research published online in the Journal of Epidemiology & Community Health. Men and those not in work seemed to be the most vulnerable, the findings indicate. The evidence suggests that supportive social networks and strong relationships are good for general health and wellbeing, but the authors wanted to find out if the stressors inherent in family relationships and friendships had any impact on the risk of death from any cause. They therefore ...

Hurricanes Katrina and Rita may have been responsible for up to half of all recorded stillbirths in the worst hit areas, suggests research published online in the Journal of Epidemiology & Community Health. And the true fetal death toll may even be higher, because of the displacement of people whose homes and way of life were destroyed, suggest the authors. Hurricane Katrina struck the state of Louisiana, USA, on August 29 2005, followed by Hurricane Rita a month later on September 24. Katrina was the costliest natural disaster in American history, while Rita was the ...

A team of scientists has found that the woody growth of forests in north Borneo is half as great again as in the most productive forests of north-west Amazonia, an average difference of 3.2 tons of wood per hectare per year. The new study, published today in the Journal of Ecology, examined differences in above-ground wood production (one component of the total uptake of carbon by plants) which is critically important in the global cycling of carbon. Trees are taller for a given diameter in Southeast Asia compared with South America, meaning they gain more biomass ...

CORVALLIS, Ore. – Researchers at Oregon State University have identified a specific biochemical process that can cause normal and healthy skin cells to transform into cancerous melanoma cells, which should help predict melanoma vulnerability and could also lead to future therapies. More than 70,000 cases of melanoma, the deadliest form of skin cancer, develop in the U.S. every year. The work was published today in PLoS Genetics, in work supported by the National Institutes of Health. "We believe this is a breakthrough in understanding exactly what leads to cancer ...

Highly pathogenic (dangerous) influenza strains elicit a strong immune response which can lead to uncontrolled inflammation in the lung and potentially fatal lung injury. A study published on May 8th in PLOS Pathogens demonstrates the importance of IL-27 for the control of immunopathology—damage to the lung tissue caused by the immune system—and the therapeutic potential of well-timed IL-27 application to treat life-threatening inflammation during lung infection. Alf Hamann, from Deutsches Rheuma-Forschungszentrum and Charité Universitätsmedizin Berlin, Germany, and colleagues, ...

Certain influenza strains are highly virulent—they cause more serious disease and kill more people. Some of the damage is caused by the stronger immune response such strains elicit, especially in the lung. A study published on May 8th in PLOS Pathogens identifies SOCS4 as a key regulator of the immune response against influenza virus. Lukasz Kedzierski, Sandra Nicholson, and colleagues from the Walter and Eliza Hall Institute of Medical Research and the University of Melbourne, Australia, studied mice with a mutation in the Socs4 gene, a member of a gene family whose ...

Washington, DC (May 8, 2014) — More frequent face-to-face physician visits in the month following hospital discharge may help reduce a kidney failure patient's chances of needing to be sent back to the hospital. That's the conclusion of a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN). The study also found that closer outpatient monitoring of kidney failure patients following hospital discharge could cut health care costs significantly. A major goal of health policy reform has been to reduce hospital readmissions within ...

Neurovance, Inc. today announced complete results from its phase 2a pilot study of EB-1020 SR, a non-stimulant, in adult male patients with all subtypes of ADHD (attention deficit hyperactivity disorder). EB-1020 SR is a norepinephrine- and dopamine-preferring triple reuptake inhibitor. The data showed a statistically significant improvement in ADHD symptoms on the ADHD-Rating Scale-IV (ADHD-RS-IV), the primary outcome measure, in a range similar to that reported in previously published trials with stimulants. EB-1020 SR appears to be well tolerated at the doses studied. ...

A genomic investigation by University of British Columbia researchers has revealed that a lethal parasite infecting a wide range of insects actually originated from pond scum, but has completely shed its green past on its evolutionary journey. A team led by UBC Botany Prof. Patrick Keeling sequenced the genome of Helicosporidium – an intracellular parasite that can kill juvenile blackflies, caterpillars, beetles and mosquitoes – and found it evolved from algae like another notorious pathogen: malaria. Keeling and colleagues had previously reported that malaria shared ...

Eating more fruits and vegetables may reduce the risk of stroke worldwide, according to new research in the American Heart Association's journal Stroke. Researchers conducted a meta-analysis of 20 studies published over the last 19 years to assess the effects of fruit and vegetable consumption on risk of stroke globally. The combined studies involved 760,629 men and women who had 16,981 strokes. Stroke risk decreased by 32 percent with every 200 grams of fruit consumed each day and 11 percent with every 200 grams of vegetables consumed each day. "Improving diet and lifestyle ...

Hamilton, ON (May 8, 2014) – New research from McMaster University suggests that a commonly performed test during certain types of heart surgery is not helpful and possibly harmful. The testing procedure, known as defibrillator testing (DT), is commonly used on people who require implantable cardioverter-defibrillators (ICDs) to prevent sudden cardiac death. It involves putting the patient into cardiac arrest to determine if the defibrillator can first recognize, then successfully shock the patient back into a normal heart rhythm. It requires the use of general anesthesia ...
