At the current pace of research and development, global oil will run out 90 years before replacement technologies are ready, says a new University of California, Davis, study based on stock market expectations. The forecast was published online Monday (Nov. 8) in the journal Environmental Science & Technology. It is based on the theory that long-term investors are good predictors of whether and when new energy technologies will become commonplace. "Our results suggest it will take a long time before renewable replacement fuels can be self-sustaining, at least ...

A team of international researchers led by ancient DNA experts from the University of Adelaide has resolved the longstanding issue of the origins of the people who introduced farming to Europe some 8000 years ago. A detailed genetic study of one of the first farming communities in Europe, from central Germany, reveals marked similarities with populations living in the Ancient Near East (modern-day Turkey, Iraq and other countries) rather than those from Europe. Project leader Professor Alan Cooper, Director of the Australian Centre for Ancient DNA (ACAD) at the University ...

Astronomers at The University of Warwick and the University of Sheffield have helped discover an unusual star system which looks like, and may even once have behaved like, a game of snooker. The University of Warwick and Sheffield astronomers played a key role in an international team that used two decades of observations from many telescopes around the world. The UK astronomers helped discover this "snooker like" star system through observations and analysis of data from an astronomical camera known as ULTRACAM designed by the British researchers on the team. They ...

Kyoto, Japan -- As if borrowing from a scene in a science fiction movie, researchers at Kyoto University have successfully developed a kind of tractor beam that can be used to manipulate the network of the molecules. In a paper soon to be published in Physical Review Letters, the team has demonstrated a technique using terahertz pulses that could have broad applications in the chemical and pharmaceutical industries. Terahertz waves, an area of specialty for the Koichiro Tanaka lab at Kyoto University's Institute for Integrated Cell-Material Sciences (iCeMS), exist in ...

A recommendation letter could be the chute in a woman's career ladder, according to ongoing research at Rice University. The comprehensive study shows that qualities mentioned in recommendation letters for women differ sharply from those for men, and those differences may be costing women jobs and promotions in academia and medicine. Funded by the National Science Foundation, Rice University professors Michelle Hebl and Randi Martin and graduate student Juan Madera, now an assistant professor at the University of Houston, reviewed 624 letters of recommendation for 194 ...

Membrane-associated receptors, channels and transporters are among the most important drug targets for the pharmaceutical industry. The search for new drugs resembles looking for a needle in a haystack. Therefore new analytical techniques are required which facilitate the simultaneous screening of a large library of compounds across a variety of membrane proteins. However, this class of methods is still at the early stages of development. The group of Prof. Dr. Robert Tampé, in collaboration with the Walter Schottky Institute at Technical University Munich, has now presented ...

Quantum computers should be much easier to build than previously thought, because they can still work with a large number of faulty or even missing components, according to a study published today in Physical Review Letters. This surprising discovery brings scientists one step closer to designing and building real-life quantum computing systems – devices that could have enormous potential across a wide range of fields, from drug design, electronics, and even code-breaking. Scientists have long been fascinated with building computers that work at a quantum level – so small ...

This release is available in German. Hormones, growth factors and several proteins ensure that development occurs in the right way, at the right time. The components that cause breast development in mammals, for example, were thought to be largely known. However, as a team of scientists from Göttingen, Frankfurt and Hanover have now discovered, in the case of breast development, hormones and proteins do not account for the full story. The scientists have shown that tiny ribonucleic acid molecules play a key role in this process. The mammary glands of mice lacking the ...

Researchers suspect that a protein superstructure called amyloid beta is responsible for much of the neural damage of Alzheimer's disease. A new study at the University of California, San Diego, shows that amyloid beta disrupts one of the brain's anti-oxidant proteins and demonstrates a way to protect that protein, and perhaps others, from amyloid's harmful effects. "Amyloid seems to cause damage to cells," said chemistry professor Jerry Yang. "We have reported in a very detailed way one potential interaction of how amyloid can cause disease, and we found a way to ...

VIDEO: University of Chicago psychologist Susan Levine has found that early exposure to mathematics words prepares students for success later in school. Click here for more information. The amount of time parents spend talking about numbers has a much bigger impact on how young children learn mathematics than was previously known, researchers at the University of Chicago have found. For example, children whose parents talked more about numbers were much more likely to ...

Whales exhibit skin damage consistent with acute sunburn in humans, and it seems to be getting worse over time, reveals research published this week in Proceedings of the Royal Society B. Scientists from the Zoological Society of London (ZSL), Queen Mary, University of London and CICIMAR, studied blue whales, fin whales and sperm whales in the Gulf of California to determine the effect of rising levels of ultraviolet radiation (UVR) on their health. For a number of years scientists have observed blisters on the skin of whales. Now, using high-quality photos to give ...

Swiss researchers studying the projected effects of climate change on alpine plant species have discovered that mountain ranges may represent a 'safer' place to live during changing climate conditions. The research, published in the Journal of Biogeography, finds that the habitat diversity of mountain ranges offer species 'refuge habitats' which may be important for conservation. The research, led by Daniel Scherrer and Christian Körner from the University of Basel, Switzerland, was carried out over two seasons in the Swiss Central Alps at 2500m. The authors used a high ...

KINGSTON, R.I. – November 9, 2010 – The heat radiating off roadways has long been a factor in explaining why city temperatures are often considerably warmer than nearby suburban or rural areas. Now a team of engineering researchers from the University of Rhode Island is examining methods of harvesting that solar energy to melt ice, power streetlights, illuminate signs, heat buildings and potentially use it for many other purposes. "We have mile after mile of asphalt pavement around the country, and in the summer it absorbs a great deal of heat, warming the roads up to ...

Whether cognitive differences exist between modern humans and Neanderthals is the subject of contentious disputes in anthropology and archaeology. Because the brain size range of modern humans and Neanderthals overlap, many researchers previously assumed that the cognitive capabilities of these two species were similar. Among humans, however, the internal organization of the brain is more important for cognitive abilities than its absolute size is. The brain's internal organization depends on the tempo and mode of brain development. Based on detailed measurements of internal ...

Philadelphia – Nov. 9, 2010 – New research shows a gene-based test for lung cancer risk can help identify which smokers are most likely to benefit from CT screening for lung cancer, according to results of a study presented today at the American Association of Cancer Research's Ninth Annual Conference on Frontiers in Cancer Prevention Research. In studies that included 1,216 lung cancer cases and 1,200 controls gathered from smokers and ex-smokers in three countries, the Respiragene™ gene-based predisposition test accurately identified a subgroup of very high risk smokers ...

A new study of young offenders has revealed they have a significantly higher rate of Traumatic Brain Injury (TBI) than that expected in society as a whole. Researchers at the University of Exeter also found TBI was associated with a greater number of convictions and, when there were three or more TBIs, greater violence in offending. The research, published online on 10 November in the journal Neuropsychological Rehabilitation, suggests brain injury must be taken seriously in the assessment and management of offenders. Professor Huw Williams, from the University of ...

Parts of at least 1,069 tigers have been seized in tiger range countries over the past decade, according to new analysis of tiger seizures carried out by TRAFFIC, the wildlife trade monitoring network. Reduced to Skin and Bones shows that from January 2000 to April 2010, parts of between 1,069 and 1,220 tigers were seized in 11 of the 13 tiger range countries—or an average of 104 to 119 animals per year. Of the 11, India, China and Nepal ranked highest in the number of tiger part seizures, the report states, with India by far the highest number of tiger part seizures ...

Speaking two languages can be handy when traveling abroad, applying for jobs, and working with international colleagues, but how does bilingualism influence the way we think? In the current issue of Psychological Science in the Public Interest, a journal of the Association for Psychological Science, Ellen Bialystok (York University), Fergus I.M. Craik (Rotman Research Institute), David W. Green (University College London), and Tamar H. Gollan (University of California, San Diego) review the latest research on bilingualism and ways in which knowing two languages can change ...

"Lupus is a significant disease with a major impact on QoL of children around the world. This is a chronic, unremitting disease that we need to get under better control," said Thomas J.A. Lehman, M.D., chief of Pediatric Rheumatology at Hospital for Special Surgery, who was involved with the study. "We have done better at treating ...

The number of Americans who report being aware of chronic obstructive pulmonary disease, or COPD, increased by 4 percentage points between 2008 and 2010, but many people at risk are still unaware of the disease, according to mailed survey results released today by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health. Sixty-nine percent of adults said they are aware of COPD. However, up to 30 percent of Americans reported that they were unaware of the condition. Awareness increased steadily among current and former smokers as ...

New Rochelle, NY, November 9, 2010—The link between maternal cigarette smoking during pregnancy and Sudden Infant Death Syndrome (SIDS) may relate to the negative effects of nicotine on the development of brain centers that regulate breathing, according to an article in the recent issue of Pediatric Allergy, Immunology, and Pulmonology, a peer-reviewed journal published by Mary Ann Liebert, Inc. (www.liebertpub.com). The article is available free online at www.liebertpub.com/ped SIDS is the leading cause of death during the first year of an infant's life. The link between ...

The benefits of collaborative, multidisciplinary care of patients with complex autoimmune diseases like lupus and multiple sclerosis are just beginning to be appreciated by physicians. Hospital for Special Surgery in New York will present evidence of the advantages of such a specialized disease center dedicated to comprehensive lupus care at the 74th Annual Meeting of the American College of Rheumatology in Atlanta. "Every time a patient comes in for an appointment, I am able to greet them personally, to find out what is going on in their lives and what may be bothering ...

A new study using a pig model of cystic fibrosis (CF) suggests that low levels of a growth promoting hormone at or before birth may contribute to growth defects in patients with CF. The study, led by University of Iowa researchers and published online the week of Nov. 8 in the Early Edition of the Proceedings of the National Academy of Sciences, could help predict the severity of the disease in patients and may lead to new therapies for growth defects in people with CF. Growth defects are common in people with CF and have been blamed, in part, on low levels of the growth-promoting ...

Charles Darwin's theory of gradual evolution is not supported by geological history, New York University Geologist Michael Rampino concludes in an essay in the journal Historical Biology. In fact, Rampino notes that a more accurate theory of gradual evolution, positing that long periods of evolutionary stability are disrupted by catastrophic mass extinctions of life, was put forth by Scottish horticulturalist Patrick Matthew prior to Darwin's published work on the topic. "Matthew discovered and clearly stated the idea of natural selection, applied it to the origin of ...
