GAINESVILLE, Fla. --- When it comes to public access, the tree of life has holes. A new study co-authored by University of Florida researchers shows about 70 percent of published genetic sequence comparisons are not publicly accessible, leaving researchers worldwide unable to get to critical data they may need to tackle a host a problems ranging from climate change to disease control. Scientists are using the genetic data to construct the largest open-access tree of life as part of the National Science Foundation's $5.6-million Assembling, Visualizing and Analyzing ...

Memphis, Tenn. – Providing families with diabetic children access via pager to a transport team improves outcomes and efficiency, according to a recent study performed at Le Bonheur Children's Hospital and The University of Tennessee Health Science Center (UTHSC). The study, "Real-time Support of Pediatric Diabetes Self-care by a Transport Team," was reported online ahead of print in Diabetes Care, the world's leading journal for clinical diabetes research and published by the American Diabetes Association. Brandi E. Franklin, PhD, assistant professor in the UTHSC College ...

COLUMBUS, Ohio – Spool-like proteins called histones play a crucial role in packaging the nearly seven feet of DNA found in most human cells. A new study shows that a group of histones that are thought to behave the same way actually are functionally distinct proteins. The findings by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC – James) indicate that replication-dependent histone isoforms can have distinct cellular functions, and that changes in expression of the ...

Hashtag #doyouknowwhoswatchingyou? A new study from USC researchers sampled more than 15 million tweets, showing that some Twitter users may be inadvertently revealing their location through updates on the social media channel. The study, which appears in the current issue of the International Journal of Geoinformatics, provides important factual data for a growing national conversation about online privacy and third-party commercial or government use of geo-tagged information. "I'm a pretty private person, and I wish others would be more cautious with the types of ...

An international group of researchers from the University of Minnesota, Argonne National Laboratory and Seoul National University have discovered a groundbreaking technique in manufacturing nanostructures that has the potential to make electrical and optical devices smaller and better than ever before. A surprising low-tech tool of Scotch Magic tape ended up being one of the keys to the discovery. The research is published today in Nature Communications, an international online research journal. Combining several standard nanofabrication techniques—with the final addition ...

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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

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 ...

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, ...

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 ...

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. ...

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, ...

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' ...

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 ...

A postdoctoral fellow from Wits University has discovered the oldest known land-living animal from Gondwana in a remote part of the Eastern Cape. Dr Robert Gess, from the Evolutionary Studies Institute at Wits, discovered the 350 million year old fossilised scorpion from rocks of the Devonian Witteberg Group near Grahamstown. This unique specimen, which is a new species, has been called Gondwanascorpio emzantsiensis. His discovery has been published in the peer reviewed journal African Invertebrate on Wednesday, 28 August 2013. Explaining his discovery, Gess said that ...

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 ...

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 ...

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 ...

The EU e-infrastructure coordination pro-iBiosphere project is preparing the ground for the pursuit of biological research in the digital age. In its "Draft policy for Open Access to data and information" scientists and lawyers recommend that hurdles posed by copyright and database protection should be removed by establishing exceptions for research in a new binding, Europe-wide regulation. This report opens a consultation process that will last until December 2013. Input is welcomed on pro-iBiosphere's Google+ , LinkedIn or Facebook. At present, national provisions ...

"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 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. ...
