TEMPE, Ariz. – A team of researchers from Arizona State University, Stanford University and Carnegie Institution for Science has found that converting large swaths of land to bioenergy crops could have a wide range of effects on regional climate.
Troy, N.Y. – Benjamin Clough has developed a novel method for eavesdropping on terahertz information hidden in invisible plasma acoustic bursts. The doctoral student at Rensselaer Polytechnic Institute has demonstrated a promising technique that employs sound waves to boost the distance from which researchers can use powerful terahertz technology to remotely detect hidden explosives, chemicals, and other dangerous materials.
CHAMPAIGN, lll. — A farmer in Niger learns how to protect his crops from insects. A resident of Port-au-Prince or a rural Haitian village learns how to avoid exposure to cholera. An entrepreneur in Mali gets step-by-step instructions on extracting the oil from shea seeds to make shea butter she can sell at a local market.
The bones of people who died up to a hundred years ago are being used in the development of new treatments for chronic back pain. It is the first time old bones have been used in this way.
The research is bringing together the unusual combination of latest computer modelling techniques developed at the University of Leeds, and archaeology and anthropology expertise at the University of Bristol.
Students' social skills and behaviour in social situations during their university studies contribute to their success in the transition to work. The social strategies adopted during university studies also have an impact on work commitment and early-career coping with working life. These results have been uncovered in a research project investigating the relationship between the social strategies students show at university and how well they cope with work-related challenges. The research has been carried out with funding from the Academy of Finland.
Researchers at North Carolina State University have developed a cheap and easy method for assembling nanowires, controlling their alignment and density. The researchers hope the findings will foster additional research into a range of device applications using nanowires, from nanoelectronics to nanosensors, especially on unconventional substrates such as rubber, plastic and paper.
Indonesia has promised to become a world leader in reducing greenhouse gas emissions. In 2009, the president committed to a 26% reduction in greenhouse gas emissions by 2020 to below 'business-as-usual' levels. Of this total, 14% would have to come from reducing emissions from deforestation or forest degradation. Investments by foreign governments and other bodies are expected to raise total emission reduction from 26% to 41%.
BOSTON, Feb. 28, 2011 – In the first study to make head-to-head comparisons between tenofovir gel and oral tenofovir – two promising approaches for preventing HIV in women – researchers found that daily use of the vaginal gel achieved a more than 100-times higher concentration of active drug in vaginal tissue than did the oral tablet, while, compared to the gel, the tablet used daily was associated with a 20-times higher active drug concentration in blood.
Scientists at Queen's University Belfast have shown that they can deliver a gene directly into breast cancer cells causing them to self-destruct, using an innovative, miniscule gene transport system, according to research published today (28 February) in the International Journal of Pharmaceutics.
A new analysis has found that supplementing the diet with fish oil may prevent muscle and weight loss that commonly occurs in cancer patients who undergo chemotherapy. Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the study indicates that fish oil may help combat cancer-related malnutrition.
Chemotherapy can cause cancer patients to lose muscle mass and become malnourished, leading to fatigue, a decreased quality of life, an inability to receive necessary treatments, and shorter survival.
Cambridge, Mass. - February 28, 2011 - There was a time when a laptop could weigh 10 pounds and still sell—a time when a cell phone was larger than a pocket—and a time when an iPod only played music.
Today's consumers expect mobile devices that are increasingly small, yet ever-more powerful. All the bells and whistles, however, suck up energy, and a phone that lasts only 4 hours because it's also a GPS device is only so much use.
DALLAS – Feb. 28, 2011 – Children who are placed with a relative because of mistreatment at home fare better in some areas than those placed in foster care, but they may have a higher risk of substance use and teenage pregnancy.
The findings by researchers at UT Southwestern Medical Center, which appear in the February issue of the Archives of Pediatrics and Adolescent Medicine, also show that relatives – also known as kinship caregivers – receive fewer support services than foster parents.
Rice University scientists and their colleagues have found that when growing corn crops for ethanol, more means less.
A new paper in today's online edition of the American Chemical Society's journal Environmental Science and Technology shows how farmers can save money on fertilizer while they improve their production of feedstock for ethanol and alleviate damage to the environment.
The research has implications for an industry that has grown dramatically in recent years to satisfy America's need for energy while trying to cut the nation's reliance on fossil fuels.
