Bochum's physicists led by Prof. Dr. Hartmut Zabel have demonstrated the spin pumping effect in magnetic layers for the first time experimentally. The behaviour of the spin pumping had previously only been predicted theoretically. The research team at the RUB has now succeeded in measuring the effect using ultrafast X-ray scattering with picosecond resolution. Through their rotation of the magnetic moments, the so-called magnetic precession, single electrons can mutually influence each other's rotation (spin) through a non-magnetic intermediate layer. This is a crucial ...

Jerusalem, Sept. 11, 2011 -- Researchers at the Hebrew University of Jerusalem have identified the key signal that prompts production of insulin-producing beta cells in the pancreas -- a breakthrough discovery that may ultimately help researchers find ways to restore or increase beta cell function in people with type 1 diabetes. The work on the multi-year project was led by Prof. Yuval Dor of the Institute for Medical Research Israel-Canada of the Hebrew University, researchers from the Hadassah University Medical Center and researchers from the diabetes section of the ...

Choosing the sex of our offspring may seem totally beyond our control, but some animals have a remarkable capacity to manipulate this. The female eclectus parrot, for example, has been known to produce 20 sons in a row before switching to producing only daughters. Now, a team of evolutionary biologists has found that tight control over offspring sex ratios can have disastrous consequences for sexual selection. Led by Dr Tim Fawcett, a research fellow at the University of Bristol, the team used mathematical models and computer simulations to investigate how sex-ratio ...

A common chemotherapy drug has been successfully delivered to cancer cells inside tiny microparticles using a method inspired by our knowledge of how the human immune system works. The drug, delivered in this way, reduced ovarian cancer tumours in an animal model by 65 times more than using the standard method. This approach is now being developed for clinical use. The research was funded by, among others, the Biotechnology and Biological Sciences Research Council (BBSRC) Follow-on Fund - funding for 'proof of concept' at the very early stage of turning research outputs ...

This press release is available in French. Toxin proteins are genetically engineered into our food because they kill insects by perforating body cell walls, and Professor Rikard Blunck of the University of Montreal's Group for the study of membrane proteins (GÉPROM) has detected the molecular mechanism involved. In recognition of his breakthrough, he received the Traditional Paul F. Cranefield Award of the Society of General Physiologists yesterday evening. "This study is about gaining a better understanding of the basic functioning of the toxin proteins in order to judge ...

The second Human Rights and Science symposium of the German National Academy of Sciences Leopoldina was held in Strasbourg. At the event scientists and scholars, representatives of human rights organisations, and delegates from European academies of sciences and humanities came together to discuss human rights violations in academic work. The ethics of biosciences were the main focus of the public symposium. Researchers regularly face human rights issues in their work. In some countries – including those in Europe – they repeatedly come against state repression if they ...

San Diego, September 12, 2011 - The Journal of Emergency Medical Services (JEMS) today announces the publication of a special 150-page four-volume digital issue featuring first-person accounts of responders who were thrust into the world spotlight the morning of September 11, 2001, when terrorists invaded their response districts – and their lives – and changed the way they, and most responders throughout the world, think, train, respond and live their lives. A.J. Heightman, Editor-in-Chief of JEMS, and Teresa McCallion, Editor of the EMS Insider newsletter – both published ...

This press release is available in Spanish. "From the point of view of efficiency, establishing one sole format for a European patent in which English is the language used for the procedure seems obvious, even though the diffusion of the innovation is translated into other EU languages," the researchers asserted. This would simplify the current system, they explained, in which the inventor can decide whether to present a European patent in English or to request the patent in the government office of his/her country and in its official language. In addition, it would ...

PHILADELPHIA (September 12, 2011) – The Academy of Natural Sciences today announced the discovery of a new species of large predatory fish that prowled ancient North American waterways during the Devonian Period, before backboned animals existed on land. Drs. Edward "Ted" Daeschler and Jason Downs of the Academy and colleagues from the University of Chicago and Harvard University describe the new denizen of the Devonian they named Laccognathus embryi in the current issue of the Journal of Vertebrate Paleontology. The 375-million-year-old beast was discovered by the ...

Earth's coral reefs have not been faring well in recent decades, facing multiple threats from pollution, disease, elevated water temperatures, and overfishing. Often referred to as the "rainforests of the Sea," coral reefs support a wide variety of marine life, help protect shorelines, and contribute significantly to tourism and the fishing industry. A new study looks at a rare but catastrophic impact on reefs: the damage caused by natural disasters such as an earthquakes. In May of 2009, a powerful, magnitude-7.3 earthquake shook the western Caribbean, causing lagoonal ...

Since 2001, New York has restricted cellphone use while driving. Drivers could receive traffic citations, with up to a $185 fine, for using handheld cellphones while driving. Law enforcement officials, however, have found that the possibility of a ticket is not enough of a deterrent as drivers continue to talk on handheld cellphones and text while driving -- and, even worse, continue to cause accidents. In 2008, more than 45,000 motor vehicle accidents in New York -- about 18 percent of the state's accidents that year -- involved driver distraction or inattention. In ...

The risk of gastrointestinal (GI) bleeding needs to be considered when determining the potential preventive benefits associated with low-dose aspirin for cardiovascular disease and cancer. According to a new study in Clinical Gastroenterology and Hepatology, the use of low-dose aspirin increases the risk for GI bleeding, with the risk being increased further with accompanying use of cardiovascular disease-preventing therapies, such as clopidogrel and anticoagulants. In patients who took proton pump inhibitors (PPIs), bleeding risk decreased. Clinical Gastroenterology and ...

BUFFALO, N.Y. -- The first transgenic mouse model of a rare and severe type of autism called Timothy Syndrome is improving the scientific understanding of autism spectrum disorder in general and may help researchers design more targeted interventions and treatments. The research is described in a paper published last week by scientists at the University at Buffalo and Stanford University in the Proceedings of the National Academy of Sciences. The transgenic mouse developed at UB exhibits the repetitive physical behaviors, altered social behaviors and impaired communication ...

TORONTO, ON – A University of Toronto-led team of astronomers has observed extreme brightness changes on a nearby brown dwarf that may indicate a storm grander than any seen yet on a planet. Because old brown dwarfs and giant planets have similar atmospheres, this finding could shed new light on weather phenomena of extra-solar planets. As part of a large survey of nearby brown dwarfs – objects that occupy the mass gap between dwarf stars and giant planets – the scientists used an infrared camera on the 2.5m telescope at Las Campanas Observatory in Chile to capture repeated ...

Capturing CO2 from power stations and storing it deep underground carries no significant threat to human health, despite recently voiced fears that it might, a study has shown. Researchers found that the risk of death from poisoning as a result of exposure to CO2 leaks from underground rocks is about one in 100 million – far less than the chances of winning the lottery jackpot. Scientists from the University of Edinburgh studied historical data on deaths from CO2 poisoning in Italy and Sicily, where the gas seeps naturally from the ground because of volcanic activity. ...

Scientific research may be in decline across the globe because of growing pressures to report only positive results, new analysis suggests. A study by the University of Edinburgh examined more than 4,600 scientific research papers published between 1990 and 2007 and found a steady decline in studies in which the findings contradicted scientific hypotheses. Papers reporting null or negative findings are in principle as useful as positive ones, but they attract fewer readers and citations, so scientific journals tend to reject them. It is acknowledged among scientists ...

Researchers from North Carolina State University have developed a way to measure how badly a Wi-Fi network would be disrupted by different types of attacks – a valuable tool for developing new security technologies. "This information can be used to help us design more effective security systems, because it tells us which attacks – and which circumstances – are most harmful to Wi-Fi systems," says Dr. Wenye Wang, an assistant professor of electrical and computer engineering at NC State and co-author of a paper describing the research. Wi-Fi networks, which allow computer ...

Men take note: If you want women to remember, speak to them in a low pitch voice. Then, depending on what they remember about you, they may or may not rate you as a potential mate. That's according to a new study by David Smith and colleagues from the University of Aberdeen in the UK. Their work shows for the first time that a low masculine voice is important for both mate choice and the accuracy of women's memory. The research is published online in Springer's journal, Memory & Cognition. In a series of two experiments, Smith and colleagues show that memory in women ...

LONDON - For less than $100, poor, pregnant women in India can now give birth in a private hospital focusing on low-income families, with comparable quality to expensive, private ones. This is an alternative to overcrowded, poorly staffed government-funded hospitals. Lifespring is a rapidly growing chain of hospitals in India that provides maternity and delivery care. For one low price, as little as $90, it provides complete delivery services. This is one-third to one-half of the fees charged at other hospitals. The first pilot hospital opened in 2005. Within a year, ...

Flitting among the cool slopes of the Appalachian Mountains is a tiger swallowtail butterfly that evolved when two other species of swallowtails hybridized long ago. It's a rarity in the animal world, biologists have found. They discovered that the Appalachian tiger swallowtail, Papilio appalachiensis, evolved from mixing between the Eastern tiger swallowtail, P. glaucus, and the Canadian tiger swallowtail, P. canadensis. The Appalachian tiger swallowtail rarely reproduces with its parental species and is a unique mixture of the two in both its outward traits and ...

Impacting the lives of children across the nation, Reach Out and Read pediatricians distributed nearly 1.5 million free books during the summer of 2011. Recognized by the New York Times and MSNBC, Reach Out and Read is an early literacy initiative that prepares America's youngest children to succeed in school by partnering with doctors to prescribe books and encourage families to read together. Over an 80 day period, 28,000 pediatricians and medical providers handed out an average of 25,600 books per day - - giving out more books per day than the crowd capacity at ...

In the race to enhance the efficiency of solar cells, spending the time and effort to get tiny nanowires to line up neatly on the top of ordinary silicon wafers may not be worth the effort. An international team of researchers has for the first time demonstrated that random, haphazardly grown silicon nanowires can significantly boost the power-producing capabilities of solar cells by trapping a broad spectrum of light waves and capturing sunlight streaming in from a wide variety of angles. The nanowires, which are wrapped in a shell of silicon oxide, serve as an antireflective ...
