(March 5, 2013) – Chemists at the University of South Florida and King Abdullah University of Science and Technology have discovered a more efficient, less expensive and reusable material for carbon dioxide (CO2) capture and separation. The breakthrough could have implications for a new generation of clean-air technologies and offers new tools for confronting the world's challenges in controlling carbon.
Publishing this month in the journal Nature, the international group of scientists has identified a previously underused material – known as SIFSIX-1-Cu - ...
Gravitational telescope creates space invader mirage
2013-03-05
Abell 68, pictured here in infrared light, is one of these galaxy clusters, and it greatly boosts the power of Hubble, extending the telescope's ability to observe distant and faint objects [1]. The fuzzy collection of blobs in the middle and upper left of the image is a swarm of galaxies, each with hundreds of billions of stars and vast amounts of dark matter.
The effect of this huge concentration of matter is to deform the fabric of spacetime, which in turn distorts the path that light takes when it travels through the cluster. For galaxies that are even further away ...
Health benefits of marriage may not extend to all
2013-03-05
COLUMBUS, Ohio – Marriage may not always be as beneficial to health as experts have led us to believe, according to a new study.
Researchers made two discoveries that explain why: First, marriage provides less protection against mortality as health deteriorates, even though it does seem to benefit those who are in excellent health. Secondly, married people tend to overestimate how healthy they are, compared to others.
"We believe marriage is still good for the health of some people, but it is not equally protective for everyone," said Hui Zheng, lead author of the study ...
Heavy moms-to-be at greater risk of c-section
2013-03-05
Researchers from Norway found that women with a pre-pregnancy body mass index (BMI) of 40 had an increased risk of vacuum extraction delivery or Cesarean section (C-section). Findings that appear in Acta Obstetricia et Gynecologica Scandinavica, a journal published by Wiley on behalf of the Nordic Federation of Societies of Obstetrics and Gynecology, indicate that women with more than a 16 kg (30 lbs) weight gain during pregnancy increased their risk of forceps or vacuum extraction, and C-section.
Obesity is a global health crisis, with the World Health Organization ...
Why fish is so good for you
2013-03-05
Jena (Germany) Fish is healthy: easy to digest and with a high level of precious proteins, fish is considered an important part of a healthy diet. And with the so-called omega-3 fatty acids fish contains real 'fountains of youth'. These fatty acids – like docosahexaeonic acid (DHA) occur mostly in fatty fish like herring, salmon and mackerel. They are thought to lower the blood pressure, to strengthen the immune system and to have positive effects on the development on the nervous system and the cardiovascular system.
"Clinical studies about the intake of nutritional ...
Does the villainous 'selfish' gene undermine genome's police?
2013-03-05
PROVIDENCE, R.I. [Brown University] — For a bunch of inanimate chemical compounds, the nucleic and amino acids caught up in the infamous "selfish" segregation distorter (SD) saga have put on quite a soap opera for biologists since the phenomenon was discovered in fruit flies 50 years ago. A new study, a highlight in the March issue of the journal Genetics, provides the latest plot twist.
In TV listings the series would be described this way: "A gene exploits a rival gene's excesses, sabotaging any sperm that bear the rival's chromosome." The listing is not an exaggeration ...
Colonoscopy screening reduces risk of advanced colorectal cancer
2013-03-05
Philadelphia - A new study led by a researcher at the Perelman School of Medicine at the University of Pennsylvania adds support to current medical recommendations stating that screening colonoscopy substantially reduces an average-risk adult’s likelihood of being diagnosed with advanced colorectal cancer (CRC) in either the right or left side of the colon. In recent years, colonoscopy has begun to rapidly replace sigmoidoscopy – a procedure used to detect abnormalities in the rectum and left side of the colon – despite initially limited evidence of its efficacy and higher ...
New spectroscopy method could lead to better optical devices
2013-03-05
PROVIDENCE, R.I. [Brown University] — A multi-university research team has used a new spectroscopic method to gain a key insight into how light is emitted from layered nanomaterials and other thin films.
The technique, called energy-momentum spectroscopy, enables researchers to look at the light emerging from a thin film and determine whether it is coming from emitters oriented along the plane of the film or from emitters oriented perpendicular to the film. Knowing the orientations of emitters could help engineers make better use of thin-film materials in optical devices ...
Shadows over data sharing
2013-03-05
In a paper about to be published in EPJ Data Science, Barbara Jasny, deputy editor for commentary at Science magazine in Washington, DC, USA, looks at the history of the debates surrounding data access during and after the human genome "war". In this context, she outlines current challenges in accessing information affecting research, particularly with regard to the social sciences, personalised medicine and sustainability.
The trouble is that most researchers do not currently share their data. This is due both to research practices and research culture. Scientists withholding ...
Herbal defluoridation of drinking water
2013-03-05
Researchers in India have developed a filter system based on a medicinal herb, which they say can quickly and easily remove "fluoride" from drinking water. The technology described in the March issue of the International Journal of Environmental Engineering uses parts of the plant Tridax procumbens as a biocarbon filter for the ion.
Drinking water can contain natural fluoride or fluoride might be added as a protective agent for teeth by water companies. However, its presence is not without controversy while in some natural drinking water levels may be above those considered ...
Kirk, Spock together: Putting emotion, logic into computational words
2013-03-05
Kirk and Spock may not need a Vulcan mind meld to share cognition: Virginia Tech Carilion Research Institute scientists have found that our cold reasoning and hot feelings may be more intimately connected than previously thought.
"We tend to believe we have rational parts, like Spock, and separate emotional parts, like Kirk. But our research suggests that's not true," said Read Montague, director of the Human Neuroimaging Laboratory at the Virginia Tech Carilion Research Institute, who led the study. "We're all a combination of logical Spock and intuitive Kirk. Cold ...

Nurse migration in North and Central America strengthening health systems
2013-03-05
International nurse migration is a multibillion-dollar global phenomenon. Historically, Mexicans and Central Americans have not played a significant part in the migration of nurses to the United States. A new report, Strengthening health systems in North and Central America: What role for migration?, sponsored by the Migration Policy Institute (MPI), seeks to draw attention to the cross-border migration in the Americas and suggests ways the migration could be managed to meet the demand for health care services in the region.
The report, co-authored by New York University ...
Gravitational lens creates cartoon of space invader
2013-03-05
The gravitational field surrounding this massive cluster of galaxies, Abell 68, acts as a natural lens in space to brighten and magnify the light coming from very distant background galaxies.
Like a fun house mirror, lensing creates a fantasy landscape of arc-like images and mirror images of background galaxies. The foreground cluster is 2 billion light-years away, and the lensed images come from galaxies far behind it.
In this photo, the image of a spiral galaxy at upper left has been stretched and mirrored into a shape similar to that of a simulated alien from the ...
EARTH: Releasing a flood of controversy on the Colorado River
2013-03-05
Alexandria, VA – As the Colorado River winds through the Colorado Plateau's soft sedimentary strata, it picks up a tremendous amount of sediment. This sediment – which once left the river's waters so muddy that Spanish explorers christened it El Rio Colorado "the reddish river" – is a vital component to the unique ecosystems of the river. However, with the construction of the Hoover and Glen Canyon dams, which trap the sediment, the once-turbid waters have become a dazzling blue-green, signaling major changes with serious implications for the health of the river's native ...
Is the iPad creative? It depends on who's buying it
2013-03-05
Encouraging consumers to feel ownership of products they haven't yet purchased can backfire because consumers tend to see themselves in the products they own, according to a new study in the Journal of Consumer Research.
"Companies assume that consumers who are made to feel ownership of a product prior to purchase will prefer it over competing products, but this can actually have the opposite effect and lead consumers to judge the product less favorably," write authors Liad Weiss and Gita V. Johar (both Columbia University).
Companies encourage us to feel a sense of ...
Product promotion: When do emotional appeals trump celebrity spokespeople?
2013-03-05
Emotional appeals could be more effective than celebrities when promoting products related to a consumer's identity, according to a new study in the Journal of Consumer Research.
"Specific emotions can help consumers strengthen their identities by providing information about how to feel a particular identity, especially when emotions are associated with distinct patterns of action. Consumers tend to choose products that bolster emotions associated with a particular identity," write authors Nicole Verrochi Coleman (University of Pittsburgh) and Patti Williams (Wharton ...
Novel small molecules used to visualize prostate cancer
2013-03-05
Two novel radiolabeled small molecules targeting prostate-specific membrane antigen (PSMA) have excellent potential for further development as diagnostic and therapeutic radiopharmaceuticals, according to research published this month in The Journal of Nuclear Medicine. The imaging agents—123I-MIP-1072 and 123I-MIP-1095—were shown to have a high sensitivity of lesion detection in bone, soft tissue and the prostate gland with minimal retention in non-target tissue.
An estimated 238,500 men will be diagnosed with prostate cancer in 2013, and 29,700 will die from the disease. ...
Are new national policies designed to reduce hospital readmissions working?
2013-03-05
New Rochelle, NY, March 5, 2013–Reducing preventable hospital readmissions is a cornerstone of emerging healthcare policy. The U.S. government has developed payment policies that will decrease payments to hospitals with excess patient readmission levels, for example. Early lessons learned from these current policy initiatives hint at their likelihood for success and are examined in an insightful article in Population Health Management, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Population Health Management website ...
EEG patterns indicate when patients lose, regain consciousness under propofol anesthesia
2013-03-05
Massachusetts General Hospital (MGH) investigators have identified specific EEG (electroencephalogram) signatures that indicate when patients lose and regain consciousness under the general anesthetic drug propofol. Their report being published online in PNAS Early Edition is part of a major MGH-based investigation into the mechanisms behind general anesthesia and builds on the results of a November 2012 paper.
"We have discovered highly structured EEG patterns that indicate when people are sedated during administration of propofol, when they are unconscious and when ...
Seniors who play video games report better sense of emotional well-being
2013-03-05
New research from North Carolina State University finds that older adults who play video games report higher levels of emotional well-being.
Researchers asked 140 people aged 63 and older how often they played video games, if at all. The study participants then took a battery of tests to assess their emotional and social well-being. 61 percent of study participants played video games at least occasionally, with 35 percent of participants saying they played at least once per week.
The study found that participants who played video games, including those who only played ...
Before and after: Ad placement should reflect cultural conceptions of time
2013-03-05
Consumers respond more favorably to advertising when the placement of product images is consistent with the way they visualize time, according to a new study in the Journal of Consumer Research.
"Whether a product's image is placed on the left or the right of an advertisement matters for products promising results occurring over time (weight loss aids or anti-aging creams) or products that are valued because they are old or new (antique furniture, modern art, wine, new technologies)," write authors Boyoun (Grace) Chae and JoAndrea Hoegg (both University of British Columbia).

2013-03-05
MINNEAPOLIS/ST. PAUL (March 5, 2013) – Researchers at the University of Minnesota's Lillehei Heart Institute have combined genetic repair with cellular reprogramming to generate stem cells capable of muscle regeneration in a mouse model for Duchenne Muscular Dystrophy (DMD).
The research, which provides proof-of-principle for the feasibility of combining induced pluripotent stem cell technology and genetic correction to treat muscular dystrophy, could present a major step forward in autologous cell-based therapies for DMD and similar conditions and should pave the way ...
The Joint Facial and Invasive Neck Trauma (J-FAINT) Project, Iraq and Afghanistan 2003-2011
2013-03-05
Alexandria, VA — With over 37,000 face and neck injuries in more than 7,000 military personnel during Operations Iraqi Freedom (OIF) and Enduring Freedom (OEF), a new study in Otolaryngology–Head and Neck Surgery concludes additional training in the management of these injuries and improvements in body armor could be beneficial.
The authors note that OIF and OEF have changed the way military surgeons approach facial and penetrating neck trauma. "This study highlights the need for a trained head and neck surgeon in the deployed environment to address these changes and ...
Comparison investing: Why are consumers more willing to take risks when they can compare products?
2013-03-05
Consumers are more willing to take risks and accept delays in exchange for greater benefits when they are able to compare products, according to a new study in the Journal of Consumer Research.
"Rationally speaking, consumer preferences should be the same whether their product choices are presented side-by-side and evaluated comparatively or presented one at a time and evaluated in isolation, but it makes a remarkable difference in consumer decision-making," write authors Christopher K. Hsee (University of Chicago Booth School of Business), Jiao Zhang (University of Miami), ...
