URBANA – In the search for the perfect crop for biofuel production, Miscanthus has become the darling to many. But in an effort to not be charmed by its enormous potential for biomass production, researchers at the University of Illinois are taking a careful look at the pros and cons of its behavior in the field. A recent study analyzed water quantity and quality in plots of Miscanthus, switchgrass, corn, and soybeans and found that Miscanthus used substantially more water, but reduced the potential for nitrogen pollution to water bodies. "We found that Miscanthus ...

A robot deceives an enemy soldier by creating a false trail and hiding so that it will not be caught. While this sounds like a scene from one of the Terminator movies, it's actually the scenario of an experiment conducted by researchers at the Georgia Institute of Technology as part of what is believed to be the first detailed examination of robot deception. "We have developed algorithms that allow a robot to determine whether it should deceive a human or other intelligent machine and we have designed techniques that help the robot select the best deceptive strategy to ...

OTTAWA – September 9, 2010 --- New analysis of a landmark health survey by the University of Ottawa Heart Institute (UOHI) shows that 70% of Ontario adults are either overweight or obese, and have a strong prevalence of high blood pressure that could lead to heart attack or stroke. The research, led by Dr. Frans Leenen of the Heart Institute's Hypertension Unit, adds new information to a limited amount of Canadian data on obesity and high blood pressure. The analysis further strengthens the link between high blood pressure and above normal Body Mass Index (BMI), a formula ...

AUSTIN, Texas—People are more likely to remember specific information such as faces or words if the pattern of activity in their brain is similar each time they study that information, according to new research from a University of Texas at Austin psychologist and his colleagues. The findings by Russell Poldrack, published online today in the journal Science, challenge psychologists' long-held belief that people retain information more effectively when they study it several times under different contexts and, thus, give their brains multiple cues to remember it. "This ...

It's no secret: the United States is in the thick of a "green trend." Increased awareness of and commitment to sustainability and improving the environment through reduced carbon emissions and energy use have led to more consumer demand for "green" products, including green construction. Even with the downturn in the housing market, a 2008 poll showed that 91 percent of registered voters nationwide would still pay more for a house if that meant a reduced impact on the environment. The same is true for the commercial building industry, as construction companies prioritize ...

Johns Hopkins researchers have determined why certain stem cells are able to stay stem cells. The report in the June 4 issue of Cell Stem Cell reveals that an enzyme that changes the way DNA is packaged in cells allows specific genes to be turned on and off, thereby preventing a stem cell from becoming another cell type. Each cell has to fit in 6 feet of highly organized and carefully packaged DNA. Some regions of the DNA are more tightly compacted than others and this structure is dynamic. There are specific enzymes that change how condensed the DNA is to help turn ...

As children in Western cultures grow, they learn to place numbers on a mental number line, with smaller numbers to the left and spaced further apart than the larger numbers on the right. Then the number line changes to become more linear, with small and large numbers the same distance apart. Children whose number line has made this change are better at remembering numbers, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. Remembering numbers is an important skill—in life, which is full of social security ...

A risk may be posed, for example, by luggage left in a public place which may contain explosives or other dangerous substances. Terror attacks based on this tactic have already claimed many civilian lives. Luggage surveillance is particularly important at airports, railway stations, trade fairs, and public spaces in nationally significant infrastructure. The aim of the SUBITO project, which is funded by the European Commission, is to improve image analysis technology in existing CCTV systems. With the help of an application developed as part of the project, cameras recognise ...

Montreal, September 9th, 2010 – An investigation published in The Journal of Sexual Medicine has found that male partners who express greater support, attention and sympathy to women's chronic vulvovaginal pain may trigger more pain, but also increase sexual satisfaction in female partners. Women who took part in the study, conducted by the University of Montreal and University of Montreal Hospital Research Centre, suffer from a condition called provoked vestibulodynia (PVD). A condition that affects 12 percent of premenopausal women, PVD can impair sexual functioning ...

Behind every coincidence lies a plan - in the world of classical physics, at least. In principle, every event, including the fall of dice or the outcome of a game of roulette, can be explained in mathematical terms. Researchers at the Max Planck Institute for the Physics of Light in Erlangen have constructed a device that works on the principle of true randomness. With the help of quantum physics, their machine generates random numbers that cannot be predicted in advance. The researchers exploit the fact that measurements based on quantum physics can only produce a special ...

Fresh insight into how plants slow their growth in cold weather could help scientists develop crops suited to cooler environments. Researchers have shown for the first time that a gene – known as Spatula – limits the growth of plants in cool temperatures, possibly helping them adjust to cool conditions. Researchers at the University of Edinburgh, who took part in the study, believe that by manipulating the gene, they could produce the opposite effect – enabling development of crops that grow well in cold climates. Scientists studied the Spatula gene in a weed known ...

One third of the world's population is infected with Mycobacterium tuberculosis (MTB), which leads to tuberculosis (TB), a leading cause of death world-wide. A new discovery, led by a team of researchers from Case Western Reserve University School of Medicine, offers hope for new approaches to the prevention and treatment of TB. The team's discovery of a novel mechanism that may contribute to immune recognition of MTB is published in the September issue of Nature Structural and Molecular Biology. Most individuals with TB recover from the initial infection and become asymptomatic, ...

Title: Personalized Medicine's Ragged Edge Author: Leonard M. Fleck Summary: The phrase "personalized medicine" has a built-in positive spin. But little attention has been given to some challenging issues of justice it raises. Some people will clearly benefit a lot, some people will clearly not benefit at all, and ...

(WASHINGTON, September 9, 2010) – For cancer patients, who have an increased risk of developing venous thromboembolism (VTE) due to a hyperactive blood coagulation system, there is now an enhanced risk model to predict their chance of developing blood clots, according to a recent study published today in Blood, the journal of the American Society of Hematology. VTE, the formation of blood clots in the veins, develops in up to 20 percent of cancer patients and is one of the leading causes of death among this patient population. Patients with hematologic malignancies (blood ...

COLLEGE STATION, Sept. 9, 2010 – DNA analysis is poised to experience a significant advancement thanks to the work of a Texas A&M University chemical engineer, who has discovered a way to achieve more effective separation of DNA fragments. Working with a widely used gelatin substance known as a hydrogel, Victor M. Ugaz, associate professor in the university's Artie McFerrin Department of Chemical Engineering, and graduate student Nan Shi have been able to determine the specific type of conditions that result in the optimum gel pore structure for separation of a wide range ...

As speech recognition systems become more commonplace - on the computer desktop top, at the call centre and even in the car - it is increasingly important to ensure that the voice signal is as clear as possible before it is processed by a computer and acted upon. It could mean the difference between anything from a profitable financial deal to a safe vehicle or aircraft maneuver. Similarly, mobile phone conversations and even the clandestine recording of speech for security and law enforcement purposes could benefit. Now, researchers at the University Campus in Tunis, ...

The existence of Dark Matter particles in the Sun's interior seems inevitable, despite dark matter never having been observed (there or elsewhere), despite intensive ongoing searches. Once gravitationally captured by the Sun, these particles tend to accumulate in its core. In a paper to be published in the scientific journal " Science", Dr. Ilidio Lopes and Professor Joseph Silk propose that the presence of dark matter in the Sun's interior causes a significant drop in its central temperature. Their calculations have shown that, in some dark matter scenarios, an isothermal ...

A survey in the latest issue of the Hastings Center Report found that most hospices in Oregon, the first state to legalize physician-assistance in dying, either do not participate in or have limited participation in requests for such assistance. Both legal and moral reasons are identified. This finding is significant because hospices are considered important for assuring that physician-assisted death is carried out responsibly, write the authors, Courtney S. Campbell, the Hundere Professor of Religion and Culture at Oregon State University, and Jessica C. Cox, the Hundere ...

Ghent, 9 September 2010 – Factoring the planet's multi-trillion dollar ecosystem services into policy-making can help save cities and regional authorities money while boosting the local economy, enhancing quality of life, securing livelihoods and generating employment. This is the finding from a major international study, launched in a report by TEEB for Local and Regional Policy Makers, being released in Belgium, Brazil, India, Japan and South Africa.
