The research aircraft Polar 5 of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association returned to Bremerhaven from a six-week expedition in the high Arctic on May 6. Joint flights with aircraft of the European and American space agencies (ESA and NASA) were a novelty in sea ice research: Simultaneous measurements with a large number of sensors on three planes underneath the CryoSat-2 satellite led to unique data records. Furthermore, the international team composed of 25 scientists and engineers collected data on trace gases, aerosols ...

A new study offers hope for species such as the Siberian Tiger that might be considered 'too rare to save', so long as conservation efforts can target key threats. The findings have important implications for conserving some of the world's most charismatic endangered species, which often exist in populations far smaller than the many thousands of individuals that earlier studies had argued were necessary for viability. Charismatic examples include the mountain gorilla, which likely now number 1,000 or less, the approximately 450 remaining Amur or Siberian tigers, ...

Eileen Schuh's THE TRAZ is a novel that addresses head-on the issues behind juvenile delinquency and exposes the adults who exploit these troubled teens. "The girl was 12," the headline says, "when she killed her parents and younger brother in their Medicine Hat, Alta. home..." Perhaps even more troubling is this headline: "Imani Nakpangi was sentenced to five years in jail for forcing the girls, 14 and 15 years of age, into prostitution..." "A 14-year-old boy was charged," reads another, "when a would-be pot buyer ...

As plant scientists unravel the genomes of plant pathogens, comparisons can be made of the different and not-so-different invasion strategies for the organisms that threaten crops. John McDowell, associate professor of plant pathology at Virginia Tech, points out similarities in the strategies of several devastating rusts and mildew. Based on his own research and the published findings of other scientists, McDowell observes shared traits that different microbes have evolved to survive as absolutely dependent on their hostile hosts – and that can be targeted to turn on ...

Decades after the pit closures, coalfield communities still face significant health problems and economic difficulties, according to new research. A Durham University-led study shows that health problems including long term limiting illnesses such as chronic arthritis, asthma and back problems, are significantly more likely in some of these areas. However, the results, published in the Journal, Health and Place, also reveal that some less deprived coalfield areas are faring relatively well in terms of health. Some of these areas seem to have weathered the economic ...

The majority of seaports around the world are unprepared for the potentially damaging impacts of climate change in the coming century, according to a new Stanford University study. In a survey posed to port authorities around the world, the Stanford team found that most officials are unsure how best to protect their facilities from rising sea levels and more frequent Katrina-magnitude storms, which scientists say could be a consequence of global warming. Results from the survey are published in the journal Climatic Change. "Part of the problem is that science says that ...

A variation in a gene involved in regulating cholesterol in the bloodstream also appears to affect progesterone production in women, making it a likely culprit in a substantial number of cases of their infertility, a new study from Johns Hopkins researchers suggests. The Hopkins group has also developed a simple blood test for this variation of the scavenger receptor class B type 1 gene (SCARB1) but emphasized there is no approved therapy yet to address the problem in infertile women. Following up studies in female mice that first linked a deficiency in these receptors ...

COLUMBUS, Ohio – A new study using sophisticated brain scans shows how simple line drawings can capture the essence of a beach or a mountain for viewers just as well as a photograph would. Researchers found that viewing a "beach" scene depicted in a line drawing activated nearly the same patterns of brain activity in study participants as did viewing an actual color photograph of a beach. The same was true when people viewed line drawings and photographs of other natural scenes including city streets, forests, highways, mountains and offices. Even when researchers removed ...

WASHINGTON — Even healthy adults with a safe driving record tend to make more driving errors as they age, including potentially dangerous mistakes, such as failing to check blind spots, according to a study published by the American Psychological Association. Most studies of older drivers have focused on people with dementia or other conditions that might impair their performance behind the wheel. This study, conducted in Australia, comprised 266 volunteers age 70 to 88 who showed no signs of dementia, lived independently and drove at least once a week. The results ...

For those soldiers worried about the stigma associated with seeing a therapist, virtual reality applications for the treatment of post-traumatic stress disorder (PTSD) may be the alternative to the traditional "talk therapy." A new paper¹, by Albert Rizzo from the University of Southern California, Institute for Creative Technologies, Los Angeles, and his team, reviews how virtual reality applications are being designed and implemented across various points in the military deployment cycle, to prevent, identify and treat combat-related PTSD. Their findings are published ...

COLUMBUS, Ohio – The anti-inflammatory drug celecoxib, known by the brand name Celebrex, triggers liver cancer cell death by reacting with a protein in a way that makes those cells commit suicide, according to a new study. Researchers also found that the combination of celecoxib with each of two chemotherapy drugs killed more liver cancer cells in culture, making those combinations more effective than either drug on its own. "Each chemotherapy drug alone will reduce the growth of cancer cells, but when each single drug is combined with Celebrex, a greater growth suppression ...

COLUMBUS, Ohio – A pattern of earthen berms, spread across a northern peninsula of the big island of Hawaii, is providing archeologists with clues to exactly how residents farmed in paradise long before Europeans arrived at the islands. The findings suggest that simple, practical decisions made by individual households were eventually adopted by the ruling class as a means to improve agricultural productivity. The research was reported in the latest issue of the journal Proceedings of the National Academy of Sciences. "Archeologically, this kind of research is really ...

Obese, asthmatic, anxious or depressed children are more likely to experience excessive daytime sleepiness, or EDS, according to Penn State College of Medicine sleep researchers. "Although EDS in children is commonly assumed by physicians and the public to be the result of sleep-disordered breathing or inadequate sleep, our data suggest that EDS in young children is more strongly associated with obesity and mood issues as it is in adults," said Edward Bixler, Ph.D., professor of psychiatry and vice chair of research, Sleep Research and Treatment Center. EDS is the inability ...

What does it take to regenerate a limb? Biologists have long thought that organ regeneration in animals like zebrafish and salamanders involved stem cells that can generate any tissue in the body. But new research suggests that multiple cell types are needed to regrow the complete organ, at least in zebrafish. Researchers at Washington University School of Medicine in St. Louis have shown that cells capable of regenerating a zebrafish fin do not revert to stem cells that can form any tissue. Instead, the individual cells retain their original identities and only give ...

(Boston) – Researchers from Boston University School of Medicine (BUSM), along with clinicians from Boston Medical Center (BMC), have found gastroenterologist knowledge of the appropriate immunizations to recommend to the inflammatory bowel disease (IBD) patient is limited. These findings, which currently appear on-line in Inflammatory Bowel Diseases, may be the primary reason why the majority of gastroenterologists believe that the primary care provider (PCP) should be responsible for vaccinations. Current therapy for IBD patients often involves agents that suppress ...

For years Professor Leo von Hemmen, a biophysicist at the TU Muenchen, and Professor Bruce Young, a biologist at the University of Massachusetts Lowell, have been researching the sense of hearing in snakes. While discussing the toxicity of their snakes, it dawned on them that only few snakes inject their venom into their victims' bodies using hollow poison fangs. Yet, even though the vast majority of poisonous reptiles lack hollow fangs, they are effective predators. Only around one seventh of all poisonous snakes, like the rattlesnake, rely on the trick with the hollow ...

TORONTO, ON – Childhood physical abuse is associated with significantly elevated rates of functional somatic syndromes such as chronic fatigue syndrome, fibromyalgia and multiple chemical sensitivities among women, according to new findings by University of Toronto researchers. The research will be published in this month's issue of the Journal of Aggression, Maltreatment & Trauma. "Women who reported they had been physically abused as children have twice the odds of chronic fatigue syndrome and multiple chemical sensitivities, and 65 per cent higher odds of fibromyalgia" ...

COLUMBUS, Ohio – Adding low doses of the targeted agent sorafenib to the chemotherapy and radiation now often used to treat head and neck cancer might significantly improve patient care and quality of life, according to a new study by researchers at the Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James). The findings suggest that adding sorafenib would maintain treatment efficacy while permitting the use of lower doses of chemotherapy and radiation and decreasing the treatment's harsh ...

Graduations are a celebration of achievement and growth, but could all the pomp and circumstance increase your risk of exposure to harmful bacteria? A team of researchers from the Johns Hopkins Bloomberg School of Public Health examined the risk of acquiring pathogenic bacteria such as Staphylococcus aureus and methicillin-resistant Staphylococcus aureus (MRSA) through shaking hands at graduation ceremonies across Maryland. A handshake, a short ritual in which two people grasp one of each other's hands, dates back as far as the 5th century BCE. This gesture has become ingrained ...
