Daejeon, Republic of Korea, Jun 15, 2015 -- Phase change random access memory (PRAM) is one of the strongest candidates for next-generation nonvolatile memory for flexible and wearable electronics. In order to be used as a core memory for flexible devices, the most important issue is reducing high operating current. The effective solution is to decrease cell size in sub-micron region as in commercialized conventional PRAM. However, the scaling to nano-dimension on flexible substrates is extremely difficult due to soft nature and photolithographic limits on plastics, thus ...

From the adventures of Lara Croft in Tomb Raider to the apocalyptic drama of Fallout - new research from the University of Warwick has revealed the secret to how some of the world's most iconic video games were created. Professor David Stark says it is because the creative teams behind these ground-breaking titles had the ideal mix of career backgrounds and working relationships. He claims his research offers a fresh insight into the factors which stimulate innovation - theories that can also apply away from the video gaming industry. The 'Big Data' analysis looked ...

Humans are unlikely to be the only animal capable of self-awareness, a new study has shown. Conducted by University of Warwick researchers, the study found that humans and other animals capable of mentally simulating environments require at least a primitive sense of self. The finding suggests that any animal that can simulate environments must have a form of self-awareness. Often viewed as one of man's defining characteristics, the study strongly suggests that self-awareness is not unique to mankind and is instead likely to be common among animals. The researchers, ...

Scientists from the Icahn School of Medicine at Mount Sinai have developed a new technique to more precisely analyze bacterial populations, to reveal epigenetic mechanisms that can drive virulence. The new methods hold the promise of a potent new tool to offset the growing challenge of antibiotic resistance by bacterial pathogens. The research was published today in the journal Nature Communications, and conducted in collaboration with New York University Langone Medical Center and Brigham and Women's Hospital of Harvard Medical School. The information content of the ...

Scientists at Helmholtz Zentrum München have now discovered how Epstein-Barr virus (EBV) conceals itself in human cells. A main culprit for its bad visibility by the immune system is the viral protein LMP2A. As published in the scientific journal PLOS Pathogens, the protein helps EBV-infected cells hide from T cells. This camouflage through the LMP2A protein may play a major role in the causation of cancer by EBV. „We suspected that a viral protein was behind EBV's camouflage in cancerous cells", says Dr. Andreas Moosmann from the Research Unit Gene Vectors ...

ANN ARBOR, Mich. -- After this year's legalization of powdered alcohol, some states have already banned it -- a move that the majority of the public supports, according to a new University of Michigan C.S. Mott Children's Hospital National Poll on Children's Health. Adults across the country share the same top concern about the new alcohol-on-the-go product: potential misuse among underage youth. Packaged in travel-friendly pouches, powdered alcohol will be available in flavors of distilled spirits like vodka and rum and also mixed drinks. One packet of powdered alcohol ...

Lisbon, 15 June 2015: In October last year the Gothenburg, Sweden, group of Mats Bra?nnstro?m announced the world's first live birth following the transplantation of a donated uterus.(1) In an editorial accompanying the report, The Lancet listed this remarkable achievement as comparable to only three other landmarks in the history of reproductive medicine: "the arrival of in-vitro fertilisation (IVF) in the late 1970s; the development of intracytoplasmic sperm injection (ICSI) in the early 1990s; the first ovarian transplant a decade ago; and [now] the first live birth ...

Lisbon, 15 June 2015: The academic performance of children conceived by assisted reproduction techniques (ART) is no better or worse than that of spontaneously conceived children when assessed at the ninth grade of their school education.(1) Similarly, ART singletons and ART twins also had comparable test scores, suggesting, say the investigators, that "the higher obstetric risk" identified in ART pregnancies - and particularly in twins - "is not associated with poorer academic performance in adolescence".(2) "These findings are very important for infertile patients," ...

The American Thoracic Society has released a policy statement with recommendations for clinicians and the general public on achieving good quality sleep and getting an adequate quantity of sleep. "Sleep plays a vital role in human health, yet there is a lack of sufficient guidance on promoting good sleep health," said Sutapa Mukherjee, MBBS, PhD, chair of the committee that produced the statement. "In this statement, with an eye towards improving public health, we address the importance of good quality sleep with a focus on sleep health in adults and children; the effects ...

How light of different colours is absorbed by carbon dioxide (CO2) can now be accurately predicted using new calculations developed by a UCL-led team of scientists. This will help climate scientists studying Earth's greenhouse gas emissions to better interpret data collected from satellites and ground stations measuring CO2. By improving the understanding of how much radiation CO2 absorbs, uncertainties in modelling climate change will be reduced and more accurate predictions can be made about how much Earth is likely to warm over the next few decades. Previous methods ...

Background: According to Sturgis, the incidence of HPV-positive oropharyngeal carcinoma has increased dramatically in recent years. Although patients with HPV-positive disease have a better prognosis than those with HPV-negative disease, researchers are still seeking a better understanding of what group of patients is more likely to respond to treatment. How the Study Was Conducted: Sturgis and colleagues used blood samples from 209 patients with previously untreated oropharyngeal carcinoma, including 96 who had confirmed HPV-positive disease, and screened the samples ...

Background: Pietras said that although prognosis for breast cancer is relatively good when detected in its early stages, metastatic disease is the cause of 90 percent of all cancer-related deaths. Therefore, learning more about the metastatic process and finding new cures to inhibit disease spread is at the center of clinical attention. He explained that in order for a tumor to spread, a cancer cell must detach and traverse the vascular wall to escape into the blood stream, exit the vasculature to enter the metastatic site, and colonize the new tissue. The fact that ...

Lisbon, 15 June 2015: Women with endometriosis are at an increased risk of miscarriage and ectopic pregnancy, according to results of a huge nationwide study presented today. Moreover, women with a history of endometriosis whose pregnancies progressed beyond 24 weeks were found to be at a higher than average risk of complications, including haemorrhage (ante- and postpartum) and preterm birth. "These results indicate that endometriosis predisposes women to an increased risk of early pregnancy loss and later pregnancy complications," said the study's first author Dr Lucky ...

Medical guidance on how to care for elderly people with dementia following a hip fracture is 'sadly lacking' according to researchers at the University of East Anglia. Almost half of all people who suffer hip fractures also have dementia. But a Cochrane Review published today reveals there is no conclusive evidence on how to care for this particularly vulnerable group. The review, which was funded by the National Institute for Health Research (NIHR), highlights an urgent need for better research into what strategies improve post-operative care - both within hospital ...

More than 60,000 Australians are estimated to have reduced or discontinued their use of prescribed cholesterol-lowering statin medications following the airing of a two-part series critical of statins by ABC TV's science program, Catalyst, a University of Sydney study reveals in the latest Medical Journal of Australia. The analysis of the Pharmaceutical Benefits Scheme medication records of 191,000 people revealed that there was an immediate impact after Catalyst was aired in October 2013, with 14,000 fewer people dispensed statins per week than expected. "In the eight ...

The 2015 meeting is held 14 to 15 June in Dubrovnik, Croatia, in collaboration with the Croatian Association of Cardiology Nurses. Ms Arbjerg Højen said: "Young VTE patients are scared of having another VTE and of dying. We treat these patients in our Thrombosis Research Unit and have seen how anxious and mentally unwell they can be, even a long time after the VTE occurs. They are troubled and have a hard ...

Rome, Italy, 13 June 2015: The results of an interventional trial presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) showed that use of the disease-modifying anti-rheumatic drug hydroxychloroquine for 24 weeks did not diminish mild-moderate pain from primary hand osteoarthritis (OA). Furthermore, treatment did not improve overall physical, social and emotional wellbeing. These findings suggest that hydroxychloroquine should no longer be routinely prescribed for patients with this form of arthritis. OA is the most common type of arthritis, ...

Rome, Italy, 13 June 2015: The results of a study presented today at the European League Against Rheumatism Annual Congress (EULAR 2015) showed that, in rheumatoid arthritis (RA) patients, a good clinical response to maintenance treatment with a tumour necrosis factor inhibitor (TNFi) was maintained even when the dose was reduced by one-third. Reducing the TNFi dose by two-thirds resulted in more flares (exacerbations of symptoms and signs) but these subsided when the higher dose of TNFi was restarted, and did not adversely affect subsequent progression of any disability. ...

Time may heal all wounds, but in the case of stroke survivors, the key to better recovery is to spend more time in an intensive physical therapy program, according to a University of Florida Health study. After a stroke, the brain and body can start recovering immediately and can show improvement up to six months afterward, said UF Health researcher Janis Daly, Ph.D. But this study focused on people who had persistent disability even a year or more after completing standard care. The study found that extensive physical therapy helped them recover motor function, even ...

New ideas are bubbling up for more efficient computer memory. Researchers at UCLA and the U.S. Department of Energy's Argonne National Laboratory announced today a new method for creating magnetic skyrmion bubbles at room temperature. The bubbles, a physics phenomenon thought to be an option for more energy-efficient and compact electronics, can be created with simple equipment and common materials. Skyrmions, discovered just a few years ago, are tiny islands of magnetism that form in certain materials. If you wrapped one up into a sphere, its magnetic fields would ...

African-American adults -- particularly women -- are much more likely to know or be related to someone behind bars than whites, according to the first national estimates of Americans' ties to prisoners. The research, led by Hedwig Lee, University of Washington associate professor of sociology, reveals the racial inequality wrought by the U.S. prison boom, with potentially harmful consequences to families and communities left lacking social supports for raising children and managing households. In an article published May 20 in the Du Bois Review: Social Science Research ...

KNOXVILLE--The increasing use of video games is often blamed for children's lack of interest in physical activity, but a study by the University of Tennessee, Knoxville, recently published in the Games for Health Journal suggests that active video games may actually be a source of moderate or intense physical activity in children five to eight years old. "Our study shows video games which wholly engage a child's body can be a source of physical activity," said Hollie Raynor, director of UT's Healthy Eating and Activity Laboratory and associate professor of nutrition. ...

(June 12, 2015) New research published in this month's edition of United European Gastroenterology journal suggests that supplementation with vitamin D may impact on the intestinal barrier dysfunction associated with Crohn's disease, and could have a role in the treatment of the condition. The study is by Professor Maria O'Sullivan and Tara Raftery. Department of Clinical Medicine, Trinity Centre for Health Sciences, St. James's Hospital, Dublin, Ireland. Crohn's disease (CD) is a lifelong chronic relapsing and remitting gastrointestinal condition, characterised by inflammation, ...
