Clay key to high-temperature supercapacitors
2013-09-04
HOUSTON – (Sept. 3, 2013) – Clay, an abundant and cheap natural material, is a key ingredient in a supercapacitor that can operate at very high temperatures, according to Rice University researchers who have developed such a device.
The Rice group of materials scientist Pulickel Ajayan reported today in Nature's online journal, Scientific Reports that the supercapacitor is reliable at temperatures of up to 200 degrees Celsius (392 degrees Fahrenheit) and possibly beyond. It could be useful for powering devices for use in extreme environments, such as oil drilling, the ...
Massive storm pulls water and ammonia ices from Saturn's depths
2013-09-04
MADISON, Wis. — Once every 30 years or so, or roughly one Saturnian year, a monster storm rips across the northern hemisphere of the ringed planet.
In 2010, the most recent and only the sixth giant storm on Saturn observed by humans began stirring. It quickly grew to superstorm proportions, reaching 15,000 kilometers (more than 9,300 miles) in width and visible to amateur astronomers on Earth as a great white spot dancing across the surface of the planet.
Now, thanks to near-infrared spectral measurements taken by NASA's Cassini orbiter and analysis of near-infrared ...
Tattoos reduce chances of getting a job, new research says
2013-09-04
London (Wednesday 04 September 2013). Having a tattoo can reduce your chance of getting a job, but it depends on where the tattoo is, what it depicts and if the job involves dealing with customers, new research says.
Dr Andrew R. Timming told the British Sociological Association conference on work, employment and society in Warwick today [Wednesday 4 September] that employers were prone to view tattoos negatively. Dr Timming, of the School of Management at the University of St Andrews, said he had spoken to 15 managers involved in hiring staff about their reaction to ...
Degree is no protection against under-employment, research shows
2013-09-04
London (Wednesday 04 September 2013). Having a degree or other qualifications is no protection against under-employment in Britain, new research shows.
The British Sociological Association's conference on work, employment and society in Warwick heard today [Wednesday 4 September] that qualified women were more likely to be under-employed than unqualified ones. Qualified men were just as likely to be under-employed as unqualified ones.
Dr Surhan Cam, of School of Social Sciences at Cardiff University, said that as working hours were cut during the economic slowdown, ...
Using harsh verbal discipline with teens found to be harmful
2013-09-04
Many American parents yell or shout at their teenagers. A new longitudinal study has found that using such harsh verbal discipline in early adolescence can be harmful to teens later. Instead of minimizing teens' problematic behavior, harsh verbal discipline may actually aggravate it.
The study, from researchers at the University of Pittsburgh and the University of Michigan, appears in the journal Child Development.
Harsh verbal discipline happens when parents use psychological force to cause a child to experience emotional pain or discomfort in an effort to correct ...
Health landscape in 6 global regions reveals rapid progress and daunting challenges
2013-09-04
WASHINGTON, September 4, 2013 — In the Middle East and North Africa, heart disease, stroke, and diabetes are causing a massive amount of premature death and disability. People in Latin America and the Caribbean are living longer on the whole, yet they face increasing threats from chronic diseases. Mortality has declined in many South Asian countries, yet the number of deaths by non-communicable diseases and self-harm has skyrocketed since 1990.
These are some of the findings released by the World Bank Group and the Institute for Health Metrics and Evaluation (IHME) in ...
New method for early detection of colon cancer
2013-09-04
PHILADELPHIA — A new, highly sensitive method to detect genetic variations that initiate colon cancer could be readily used for noninvasive colon cancer screening, according to a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research.
"Tumor cells are released into stool from the surface of precancers and early-stage colon cancers, but detecting a cancer-initiating genetic mutation among a large quantity of normal DNA from a patient's stool is like looking for a needle in a haystack," said Bettina Scholtka, Ph.D., assistant ...
NUS study highlights effectiveness of community-based cardiac rehabilitation
2013-09-03
With a growing incidence of cardiovascular disease in Asia, lifestyle modification such as weight loss and routine exercise plays an important role in early primary cardiovascular disease prevention. While it is widely known that patients with cardiovascular conditions will benefit from participating in a structured cardiac rehabilitation programme, particularly in a convenient and affordable community-based setting, there is no published data that showed the effectiveness of such a programme in the Asian population to date.
With the idea of health promotion in mind, ...
Evidence of production of luxury textiles and extraction of copper from unknown part of Cypriote Bronze Age city
2013-09-03
A Swedish archaeological expedition from the University of Gothenburg has excavated a previously unknown part of the Bronze Age city Hala Sultan Tekke (around 1600-1100 BC). The finds include a facility for extraction of copper and production of bronze objects, evidence of production of luxurious textiles, as well as ceramics and other objects imported from all over the Mediterranean but also from central Europe.
'One of our conclusions is that the Bronze Age culture in Hala Sultan Tekke played a central role in the Eastern Mediterranean. Cyprus served as an important ...
Exploitation of Indian workers on 457 visas
2013-09-03
Recent research, by Dr Selvaraj Velayutham published in a forthcoming issue of The Economic and Labour Relations Review, published by SAGE, details the exploitation of Indian immigrant workers in Australia on 457 visas.
Whilst the exploitation was often by fellow-countrymen, it is the 457 visa system that makes this exploitation possible. Unless temporary immigrants accept the poor conditions offered, they face deportation. In effect they have been tricked into coming to Australia by false promises, and have often had to borrow heavily to pay dishonest recruitment agents. ...
Canine remote control
2013-09-03
That old "best friend" can get a bit tiresome, all that rolling over, shaking paws, long walks and eating every crumb of food off the floor. But, what if there were a way to command your dog with a remote control, or even via your smart phone...or even without hands?
Jeff Miller and David Bevly of the Department of Mechanical Engineering, at Auburn University, Auburn, Alabama, have devised just such a system and describe details in a forthcoming issue of the International Journal of Modelling, Identification and Control. The device based on a control suite with a microprocessor, ...
Study finds language and tool-making skills evolved at the same time
2013-09-03
Research by the University of Liverpool has found that the same brain activity is used for language production and making complex tools, supporting the theory that they evolved at the same time.
Researchers from the University tested the brain activity of 10 expert stone tool makers (flint knappers) as they undertook a stone tool-making task and a standard language test. They measured the brain blood flow activity of the participants as they performed both tasks using functional Transcranial Doppler Ultrasound (fTCD), commonly used in clinical settings to test patients' ...
Mouse groups reveal complex relationships
2013-09-03
A common belief is that our modern, stimulation-filled environment encourages individualistic behavior (or anti-social behavior, depending on one's point of view), while simpler surroundings give rise to a more developed community life. New research at the Weizmann Institute shows that this assumption – at least for mice – is based in reality: Mice that have been raised in a stimulus-rich environment have less complexity in their social interactions than those growing up in more Spartan conditions. The findings were based on two innovative developments: The first is an ...

Research could lead to a new test to predict women at risk of pregnancy complications
2013-09-03
Researchers from The University of Manchester and Central Manchester University Hospitals NHS Trust have identified proteins in the blood that could be used to predict whether a woman in her first pregnancy is at increased risk of developing pre-eclampsia.
Pre-eclampsia is a complication of pregnancy where the mother develops high blood pressure and protein is present in the urine. In some cases, this can develop into a serious condition for both mother and baby and the only cure is delivery of the baby, often prematurely.
Women who have had pre-eclampsia previously ...
Added benefit of lisdexamfetamine is not proven
2013-09-03
Lisdexamfetamine dimesylate (trade name: Elvanse) has been approved in Germany since March 2013 as part of a comprehensive treatment programme for attention deficit/hyperactivity disorder (ADHD) in children aged 6 years and over when response to previous treatment with the drug methylphenidate was inadequate. No added benefit of the drug versus the appropriate comparator therapy could be established in the assessment of the drug manufacturer's dossier according to the Act on the Reform of the Market for Medicinal Products (AMNOG). The manufacturer did not present any relevant ...
Level playing field for Clostridium difficile diagnosis
2013-09-03
The largest study of its kind has shown the most effective test for the diagnosis of Clostridium difficile (C-Diff), a bacterial infection which causes 15,000-20,000 deaths a year in hospitals in the United States.
C-Diff affects the digestive system, and is most common in hospital patients treated with antibiotics for other infections.
The multi-centre study, carried out by UK researchers at the University of Leeds, in partnership with colleagues from the University of Oxford, University College London and St George's, University of London, tested more than 12,000 ...

Recommendations on how to move the naming of organisms from paper and on to the Internet
2013-09-03
"Well, I suppose I'd better start finding names for things…" was the first thing said by the ill-fated sperm whale (Physeter macrocephalus Linnaeus, 1758) in Douglas Adam's Hitchhikers Guide to the Galaxy. Such is the richness of life that, unlike that whale, mankind is still naming things. Without commonly accepted names there would be no way to communicate research about life and it is the profession of taxonomists to put names on organisms and describe the different forms of life on Earth.
The EU e-Infrastructure coordination project "pro-iBiosphere", targeting the ...
The future of biodiversity publishing
2013-09-03
The traditional audience for books and scientific papers in which scientists report their findings has been the human reader. Now we can enhance publications by attaching to them many different kinds of digital objects (such as the sounds made by birds, maps that show where they occur, or images and videos) or by adding computer-readable sections and terms that allow computers to extract information for re-use. We refer to these enriched and marked-up documents as 'enhanced'.
While the technology is available, only a tiny proportion of scientific publications are enhanced. ...
Rim Fire update Sept. 02, 2013
2013-09-03
The Rim Fire in and around Yosemite National Park, which began on August 17, 2013 is now the fourth largest fire in California's history. According to Inciweb.org for Sept. 02, 2013: "The Rim Fire grew approximately 8,310 acres, to a total size of 231,088 acres. Burnout operations on the northern and southern portions of the fire continued with success through the night. Southwest transport winds returned smoke to the communities northeast of the fire, including Reno, Carson City, Markleeville, Minden, and the Lake Tahoe Basin, and returned clearer skies to the Yosemite ...
Action-inaction balance in cultural values more common in East Asian countries
2013-09-03
PHILADELPHIA -- People in East Asian countries seem to strike the best balance between liking action and inaction, whereas someone from the Mediterranean area of the world are far less likely to have achieved the same balance.
This balance between action and inaction is best displayed in Asia, where Labor Day is not observed until May.
A two-year-long study involving over 4,000 volunteer participants (age 19 to 30) from 19 countries and looked at the degree to which a culture holds attitudes toward rest and activity. It was led by Dolores Albarracín, Ph.D., the Martin ...

Enhanced luminal breast tumor response to antiestrogen therapy
Breast cancer can be divided into 4 major subtypes using molecular and genetic information from the tumors. Each subtype is associated with different prognosis and should be taken into consideration when making treatment decisions. In this issue of the Journal of Clinical Investigation, Rebecca Cook and colleagues at Vanderbilt University, found that expression of an oncogene, ERBB3, was enhanced in luminal breast cancers compared to other breast cancer subtypes. Addition of the ERBB3 protein to cultured ...
