WEST LAFAYETTE, Ind. - Unanticipated economic benefits from the shale oil and gas boom could help offset the costs of substantially reducing the U.S.'s carbon footprint, Purdue agricultural economists say. Wally Tyner and Farzad Taheripour estimate that shale technologies annually provide an extra $302 billion to the U.S. economy relative to 2007, a yearly "dividend" that could continue for at least the next two decades, Tyner said. Using an economic model, they found that "spending" part of this dividend on slashing the nation's carbon emissions by about 27 percent ...

Astronomers have uncovered rhythmic pulsations from a rare type of black hole 12 million light-years away by sifting through archival data from NASA's Rossi X-ray Timing Explorer (RXTE) satellite. The signals have helped astronomers identify an unusual midsize black hole called M82 X-1, which is the brightest X-ray source in a galaxy known as Messier 82. Most black holes formed by dying stars are modestly-sized, measuring up to around 25 times the mass of our sun. And most large galaxies harbor monster, or supermassive, black holes that contain tens of thousands of times ...

MIAMI – A new study that analyzed concentrations of African dust transported to South America shows large seasonal peaks in winter and spring. These research findings offer new insight on the overall human health and air quality impacts of African dust, including the climate change-induced human health effects that are expected to occur from increased African dust emissions in the coming decades. Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science and colleagues analyzed the dust concentrations in aerosol samples from two locations, ...

MIAMI – A new study of the ocean circulation patterns at the site of the Deepwater Horizon oil spill reveals the significant role small-scale ocean currents play in the spread of pollutants. The findings provide new information to help predict the movements of oil and other pollutants in the ocean. Nearly two years to the day after the Deepwater Horizon incident, scientists from the Consortium for Advanced Research on Transport of Hydrocarbon in the Environment (CARTHE), based at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, conducted ...

Although body motion sensors already exist in different forms, they have not been widely used due to their complexity and cost of production. Now researchers from the University of Surrey and Trinity College Dublin have for the first time treated common elastic bands with graphene, to create a flexible sensor that is sensitive enough for medical use and can be made cheaply. Once treated, the rubber bands remain highly pliable. By fusing this material with graphene - which imparts an electromechanical response on movement – the team discovered that the material can be ...

WASHINGTON, DC -- There is no guarantee that a successful pilot program introducing a health innovation can be expanded successfully to the national, regional, state or even metropolitan level because scaling up is typically complex and difficult. A new study from Georgetown University's Institute for Reproductive Health reports on the results of the successful large-scale implementation, in a low resource environment, of the Standard Days Method®, a highly effective fertility awareness-based family planning method developed by Institute researchers. Lessons learned ...

PROVIDENCE, R.I. [Brown University] — Men in steady same-sex relationships where both partners are HIV negative will often forgo condoms out of a desire to preserve intimacy, even if they also have sex outside the relationship. But the risk of HIV still lurks. In a new study of gay and bisexual men who reported at least one instance of condomless anal sex in the last 30 days, researchers found that the same desire for intimacy is also a strong predictor of whether men would be willing to take antiretroviral medications to prevent HIV, an emerging practice known as pre-exposure ...

SAN DIEGO, Calif. (August 19, 2014) — Daylight was breaking over the central Pacific and coffee brewing aboard the MY Hanse Explorer. Between sips, about a dozen scientists strategized for the day ahead. Some would don wetsuits and slip below the surface to collect water samples around the southern Line Islands' numerous coral reefs. Others would tinker with the whirring gizmos and delicate machinery strewn throughout the 158-foot research vessel. All shared a single goal: Be the first research group to bring a DNA sequencer out into the field to do remote sequencing in ...

CHAMPAIGN, Ill. — A new study of 9- and 10-year-olds finds that those who are more aerobically fit have more fibrous and compact white-matter tracts in the brain than their peers who are less fit. "White matter" describes the bundles of axons that carry nerve signals from one brain region to another. More compact white matter is associated with faster and more efficient nerve activity. The team reports its findings in the open-access journal Frontiers in Human Neuroscience. "Previous studies suggest that children with higher levels of aerobic fitness show greater ...

Male stickleback fish that protect their young have bigger brains than counterparts that don't care for offspring, finds a new University of British Columbia study. Stickleback fish are well known in the animal kingdom for the fact that the male of the species, rather than the female, cares for offspring. Male sticklebacks typically have bigger brains than females and researchers wanted to find out if the difference in size might relate to their role as caregivers. In the study, published recently in Ecology and Evolution, researchers compared regular male sticklebacks ...

Researchers at Children's Hospital Los Angeles have shown that a select team of immune-system cells from patients with leukemia can be multiplied in the lab, creating an army of natural killer cells that can be used to destroy the cancer cells. Results of their in vitro study, published August 19 in the journal Leukemia, could one day provide a less toxic and more effective way to battle this cancer in children. Acute lymphoblastic leukemia (ALL) is the most common cancer of childhood. This disease hinders the development of healthy blood cells while cancer cells proliferate. ...

New York, NY, August 19, 2014 – Postsurgical cognitive side effects can have major implications for the level of care, length of hospital stay, and the patient's perceived quality of care, especially in elderly and fragile patients. A nationwide survey of Swedish anesthesiologists and nurse anesthetists has found there is low awareness of the risks of cognitive side effects following surgery. Furthermore, only around half of the respondents used depth-of-anesthesia monitors. Results are published in Annals of Medicine and Surgery. Patients generally expect to make a rapid ...

The specific composition of bacterial species in a person's gut may protect against or increase susceptibility to Campylobacter, the most common cause of human bacterial intestinal inflammation, according research published this week in mBio®, the online open-access journal of the American Society for Microbiology. The study also found that Campylobacter infection can yield lasting changes to one's gut bacteria composition. "It has been known for a long time that the microbiota, or microorganisms in the gut, can protect a person from colonization by organisms that cause ...

SAN FRANCISCO — Parents are better off having daughters if they want to be cared for in their old age suggests a new study, which finds that women appear to provide as much elderly parent care as they can, while men contribute as little as possible. "Whereas the amount of elderly parent care daughters provide is associated with constraints they face, such as employment or childcare, sons' caregiving is associated only with the presence or absence of other helpers, such as sisters or a parent's spouse," said study author Angelina Grigoryeva, a doctoral candidate in sociology ...

SAN FRANCISCO — People's educational attainment influences their level of physical activity both during the week and on weekends, according to a study whose authors include two University of Kansas researchers. The study finds that, on average, those with a college degree are more active on Saturdays and Sundays than on a typical weekday — whereas for people without a high school degree, the opposite is true. "Educational attainment predicts physical activity differently on weekends and weekdays," said Jarron M. Saint Onge, a KU assistant professor of sociology and ...

SAN FRANCISCO — The Great Recession of 2007-2009 had little direct effect on the health of workers who survived the waves of job cuts that took place during that period, according to a new University of Akron study. That's the good news. The bad news may be the reason: Increased workloads and less satisfying job duties, the highly stressful byproducts of corporate restructurings during previous economic downturns, had by 2007 become the new normal in the workplace. Because of this long-term trend, workers who remained on the job during the Great Recession were already ...

SAN FRANCISCO — Nurses who are motivated primarily by the desire to help others, rather than by enjoyment of the work itself or the lifestyle it makes possible, are more likely to burn out on the job, University of Akron researchers say. Nursing is still a female-dominated occupation, and being female is associated with being caring, nurturing, and altrustic. Therefore, the desire to help others is often assumed to be the "right" motivation for entering the field, the researchers say. However, they found that nurses who pursue their career for reasons other than or ...

In recent years, a shift from inpatient to outpatient surgery in the U.S. for commonly performed urologic procedures has coincided with increasing deaths following complications that were potentially recognizable or preventable. The finding, which comes from a recent study published in BJU International, indicates the importance of monitoring urologic surgery patients for potential complications. Over the last two decades, measures to improve healthcare safety and quality have expanded significantly. In the context of surgical procedures, this has lead in a decrease in ...

Sammon, D.O., a researcher at Henry Ford's Vattikuti Urology Institute and lead author of the study discusses deaths rise with shift from in-hospital to outpatient procedures for common... Click here for more information. DETROIT – As hospitals have shifted an array of common urological surgeries from inpatient procedures to outpatient, potentially preventable deaths have increased following complications. Those were the primary findings of a new study led ...

(PHILADELPHIA) – The common thought in the medical community is that the randomized, controlled trial is the gold standard in medical research. Findings from these studies are thought to be most reliable and are often endorsed by guideline-making organizations and brought into medical practice. But, Penn Medicine researchers caution that the rapid adoption of one or two studies as the basis for clinical practice, even if they are randomized controlled trials, can lead to misinformation and potential harm. Using the case of Beta-blockers, they show how clinical practice ...

Scientists at Queen's University Belfast have made a breakthrough in the fight against the most resistant hospital superbugs. The team from the School of Pharmacy at Queen's have developed the first innovative antibacterial gel that acts to kill Pseudomonas aeruginosa, staphylococci and E. coli using natural proteins. The gels have the ability to break down the thick jelly-like coating, known as biofilms, which cover bacteria making them highly resistant to current therapies, while leaving healthy cells unaffected. Dr Garry Laverty, from the School of Pharmacy at Queen's ...

How 4-year old children draw pictures of a child is an indicator of intelligence at age 14, according to a study by King's College London, published today in Psychological Science. The researchers studied 7,752 pairs of identical and non-identical twins (a total of 15,504 children) from the Medical Research Council (MRC) funded Twins Early Development Study (TEDS), and found that the link between drawing and later intelligence was influenced by genes. At the age of 4, children were asked by their parents to complete a 'Draw-a-Child' test, i.e. draw a picture of a child. ...

Investigators at the University of Southampton have discovered that two new vaccines can prevent the transmission of meningitis bacteria from person to person. The vaccines do this by reducing 'carriage' of the responsible bacteria in the nose and throats of the population. Meningitis is a devastating condition and the Southampton team believe this discovery will change the way new vaccines are made in the future. Robert Read, Professor of Infectious Diseases at the University of Southampton, who led the study, says: "The standard practice is to vaccinate with the ...

Parents who physically neglect their boys may increase the risk that they will raise violent adolescents, according to Penn State sociologists. In a study of currently incarcerated male adolescents, physical neglect during childhood arose as the strongest predictor of violent behavior, said William McGuigan, associate professor of human development and family studies at Penn State Shenango. Researchers are just beginning to acknowledge the powerful role of neglect in influencing adolescent violence, he added. "One of the problems with studying neglect is that it is ...

New research published in Diabetologia (the journal of the European Association for the Study of Diabetes) shows that the blood-fat lowering drug fenofibrate is as effective in women with type 2 diabetes as in men with type 2 diabetes. The research is by the Fenofibrate Intervention and Event Lowering in Diabetes (FIELD) study investigators in Australia, New Zealand and Finland, led by Professor Anthony Keech from the Clinical Trials Centre at the University of Sydney, Australia, and Associate Professor Michael d'Emden, Endocrine Research Unit, Royal Brisbane Hospital, ...
