ESA's Herschel infrared space observatory has detected raging winds of molecular gas streaming away from galaxies. Suspected for years, these outflows may have the power to strip galaxies of gas and halt star formation in its tracks. The winds that Herschel has detected are extraordinary. The fastest is blowing at a speed of more than 1000 km/s, or about 10 000 times faster than the wind in a terrestrial hurricane. This is the first time that such molecular gas outflows have been unequivocally observed in a sample of galaxies. This is an important discovery because ...

'Healthy' smokers experience changes in the gene expression of their lungs similar to that suffered by smokers who have developed Chronic Obstructive Pulmonary Disease (COPD). This is the conclusion of a new study, led by Catalan researchers, which confirms the crucial role that smoking plays in causing these alterations. "Our objective was to analyse the expression of a range of genes in the pulmonary tissue samples of patients with COPD, whether smokers or not, and people who had undergone operations for cancer or lung transplants", Ricardo Bastos, lead author of the ...

A Roberts Law Group PLLC client was facing a serious statutory rape charge when attorney Patrick Roberts stepped in to defend against the charge. By challenging the credibility of the accuser, criminal lawyer Roberts was able to negotiate a reduction in the statutory rape charge to indecent liberties with a minor. This reduction led to a decrease in the amount of possible prison time from nearly 25 years to 10 to 12 months. The facts of the case aren't all that uncommon in North Carolina because many don't realize the consequences stemming from sex with a minor. In this ...

Although most commonly associated with military combat, post-traumatic stress disorder (PTSD) can occur in civilians, too – and with consequences that are just as serious, according to a new review article in the Journal of the American Academy of Orthopaedic Surgeons (JAAOS). PTSD is a type of anxiety disorder that occurs after a person experiences a traumatic event involving physical injury, and occurs in 20 to 51 percent of patients with an orthopaedic injury. "PTSD occurs with a significant frequency in civilian patients who have sustained an orthopaedic trauma, and ...

Children have poor quality sleep. A new study carried out in Valencia shows that 37.4% of children aged from 6 to 8, 25.3% of those aged between 9 and 11, and 31.8% of those aged from 12 to 15 wake up feeling refreshed only once a week, or even not at all. The results also show that 4.26% of them fall asleep in class more than three times per week. "It is important to point out that the way we sleep throughout our lives depends on how we learn to sleep as children", Gonzalo Pin Arboledas, lead author of this study and a doctor at the Valencian Sleep Unit at the Quirón ...

PITTSBURGH—Digital imagery, Facebook updates, online music collections, email threads and other immaterial artifacts of today's online world may be as precious to teenagers as a favorite book that a parent once read to them or a t-shirt worn at a music festival, Carnegie Mellon University (CMU) researchers say. The very fact that virtual possessions don't have a physical form may actually enhance their value, researchers at Carnegie Mellon's Human-Computer Interaction Institute (HCII) and School of Design discovered in a study of 21 teenagers. A fuller appreciation of ...

Taking on significant debt has become "normal"—and even patriotic—to some consumers, according to a new study in the Journal of Consumer Research. "How did America, a country once so indelibly marked with Puritan principles of self-discipline and thrift, become a nation so awash in personal debt?" ask authors Lisa Peñaloza (École des Hautes Études Commerciales du Nord—EDHEC) and Michelle Barnhart (Oregon State University). The researchers interviewed 27 white, middle-class Americans before the 2008 financial crisis and found that even though consumers believe that ...

People who read vivid print advertisements for fictitious products actually come to believe they've tried those products, according to a new study in the Journal of Consumer Research. "Exposing consumers to imagery-evoking advertising increases the likelihood that a consumer mistakenly believes he/she has experienced the advertised product, and subsequently produces attitudes that are as strong as attitudes based on genuine product experience," write authors Priyali Rajagopal (Southern Methodist University) and Nicole Montgomery (College of William and Mary). In one ...

DETROIT – Nurse-driven, open-access colonoscopy programs are as effective and safe as colonoscopy following a consultation with a gastroenterologist, according to researchers at Henry Ford Hospital. "Our results showed no significant differences in safety outcomes related to perforation rate, emergent surgery, post-polypectomy bleed, overall lower gastrointestinal bleed, or death," says Gregory Olds, M.D., chief of interventional gastroenterology and director of endoscopy at Henry Ford Hospital and co-author of the study. With a nurse-driven open access program, a ...

Consumers who set conservative goals have a harder time achieving satisfaction than those who set ambitious goals, according to a new study in the Journal of Consumer Research. When cautious consumers meet their goals, they tend to raise the bar and compare themselves to the highest possible standards. Authors Cecile K. Cho (University of California, Riverside) and Venkataramani Johar (Columbia University) compared people who set conservative goals with people who set ambitious goals. They focused on situations in which goals were achieved, and measured the level of satisfaction ...

Technologies for removing carbon dioxide from the atmosphere are unlikely to offer an economically feasible way to slow human-driven climate change for several decades, according to a report issued by the American Physical Society and led by Princeton engineer Robert Socolow. "We humans should not kid ourselves that we can pour all the carbon dioxide we wish into the atmosphere right now and pull it out later at little cost," said Socolow, a professor of mechanical and aerospace engineering. The report, issued by a committee of 13 experts, was co-chaired by Socolow ...

Every time consumers spend money on a purchase, they are giving up other consumption down the road. A new study in the Journal of Consumer Research looks at the factors that lead consumers to consider these "opportunity costs." "Rather than viewing a decision as 'Do I buy or do I not buy?' consumers feeling constrained view the decision as 'Do I buy or do I use my money on something else instead?'" writes author Stephen Spiller (UCLA). Feeling constrained is one major factor that leads consumers to consider how purchasing something now will affect what they can purchase ...

Innovative ads can help creative consumers break away from their existing thought patterns, according to a new study in the Journal of Consumer Research. These creative stimuli can affect the way consumers process information about different products. "Creative marketing stimuli are pervasive in the marketplace as marketers and advertisers scramble to break through the clutter to attract consumers' attention and win their approval," write authors Xiaojing Yang (University of Wisconsin–Milwaukee), Torsten Ringberg (Copenhagen Business School), Huifang Mao (University of ...

EAST PROVIDENCE, R.I. – Although the Centers for Disease Control and Prevention recommends routine HIV testing for everyone between the ages of 13-64 as part of their regular medical care, testing rates remain low among adolescents. However, a new study from the Bradley Hasbro Children's Research Center suggests teens who are offered free or low-cost rapid HIV testing are often willing to accept the test. According to findings published in the May 2011 issue of the Journal of Adolescent Health, more than half of all adolescents accepted a free rapid HIV test immediately ...

Knowing how long a good experience will last makes it better, but being aware of the duration of an unpleasant event makes it worse, according to a new study in the Journal of Consumer Research. But people usually predict the opposite effect. "Which is more enjoyable, knowing the exact duration of a dinner with a charming friend or not knowing it? What if the dinner is with disliked in-laws?" ask authors Min Zhao and Claire I. Tsai (University of Toronto). People often assume that knowing the duration of a pleasant event will "kill the fun," whereas knowing the duration ...

The researchers published their results in the coming issue of the scientific journal Physical Review Letters. "Attempts to calculate the Hoyle state have been unsuccessful since 1954," said Professor Dr. Ulf-G. Meißner (Helmholtz-Institut für Strahlen- und Kernphysik der Universität Bonn). "But now, we have done it!" The Hoyle state is an energy-rich form of the carbon nucleus. It is the mountain pass over which all roads from one valley to the next lead: From the three nuclei of helium gas to the much larger carbon nucleus. This fusion reaction takes place in the hot ...

WASHINGTON, May 9, 2011 — Flakes of skin that people shed at the rate of 500 million cells every day are not just a nuisance — the source of dandruff, for instance, and a major contributor to house dust. They actually can be beneficial. A new study, published in the American Chemical Society's journal, Environmental Science & Technology, concludes that oil in those skin cells makes a small contribution to reducing indoor air pollution. Charles Weschler and colleagues explain that humans shed their entire outer layer of skin every 2-4 weeks at the rate of 0.001 – 0.003 ...

Johns Hopkins scientists have discovered how two closely related proteins guide projections from nerve cells with exquisite accuracy, alternately attracting and repelling these axons as they navigate the most miniscule and frenetic niches of the nervous system to make remarkably precise connections. The discovery, reported April 28 in the journal Neuron, reveals that proteins belonging to the "semaphorin" family of guidance cues are crucial for getting neuronal projections exactly where they need to be not only across long distances, but also in the short-range wiring ...

WASHINGTON, D.C. – The American Physical Society has released a new assessment — Direct Air Capture of CO2 with Chemicals — to better inform the scientific community on the technical aspects of removing carbon dioxide from the atmosphere. In systems achieving direct air capture (DAC) of carbon dioxide (CO2), ambient air flows over a chemical sorbent, either liquid or solid, that selectively removes the CO2. The CO2 is then released as a concentrated stream for disposal or reuse, while the sorbent is regenerated and the CO2-depleted air is returned to the atmosphere. ...

WASHINGTON — A new report from the National Research Council lays out a framework for the U.S. Food and Drug Administration to systematically evaluate and compare the public health consequences of its decisions concerning a wide variety of products. Moreover, the risk-assessment framework provides a common internal language to discuss potential options and draws extensively on well-vetted risk literature to define the relevant health dimensions for FDA decision making. FDA must make decisions daily, from determining whether a certain drug should be approved to deciding ...

NEW YORK (May 6, 2011) -- Among those presenting at this year's Digestive Disease Week meeting are physician-scientists from NewYork-Presbyterian Hospital/Columbia University Medical Center. The meeting takes place May 7-10, at McCormick Place, Chicago. The following are two notable research studies: Dr. Benjamin Lebwohl A gastroenterologist at NewYork-Presbyterian Hospital/Columbia University Medical Center and instructor in clinical medicine at Columbia University College of Physicians and Surgeons The prevalence of colorectal neoplasia (CRN) among racial and ethnic ...

Surgeon and Professor Michael Olausson was able to create a new connection with the aid of this blood vessel between the liver and the intestines, necessary to cure the girl. The girl is now in good health, and her prognosis is very good. The girl developed during her first year of life a blood clot in the blood vessel that leads blood from the intestines to the liver. This introduced the risk that she would experience life-threatening internal bleeding. The condition can be cured if it is possible to direct the blood along the correct path, back into the liver. In optimal ...

Obesity appears to impair normal muscle function in rats, an observation that could have significant implications for humans, according to Penn State researchers. "Our findings demonstrate that obesity involves more than accumulating excess fat and carrying excess weight," said Rudolf J. Schilder, American Physiological Society postdoctoral fellow in physiological genomics, Penn State College of Medicine. "We show that, during the development of obesity, skeletal muscles fail to adjust their molecular composition appropriately to the increasing body weight. Consequently, ...

AURORA, Colo. (May 8, 2011) Liposuction has become one of the most popular plastic surgeries in the country. It has been around since 1974 and there are now more than 450,000 operations a year. But does the fat come back? A recent study by Teri L. Hernandez, PhD, RN and Robert H. Eckel, MD, at the University of Colorado School of Medicine have found that the fat eventually returns within one year, and is redistributed to other areas of the body, especially the upper abdomen. There was further redistribution around the shoulders and triceps of the arms. "The fact ...
