As the U.S. policy makers renew emphasis on the use of nuclear energy in their efforts to reduce the country's oil dependence, other factors come into play. One concern of paramount importance is the seismic hazard at the site where nuclear reactors are located. Russell A. Green, associate professor of civil and environmental engineering at Virginia Tech, spent five years as an earthquake engineer for the U.S. Defense Nuclear Facilities Safety Board in Washington, D.C., prior to becoming a university professor. Part of his responsibility at the safety board was to perform ...

Iron furnaces that once dotted central Pennsylvania may have left a legacy of manganese enriched soils, according to Penn State geoscientists. This manganese can be toxic to trees, especially sugar maples, and other vegetation. The research, which quantified the amounts of manganese in soil core samples, was part of work done at the Shale Hills Critical Zone Observatory funded by the National Science Foundation. "Our group's focus was to study the soil chemistry," said Elizabeth M. Herndon, graduate student in geosciences. "We saw excess manganese in the soil and ...

Children with ADHD can sometimes have more difficulties on math and reading tests compared to their peers. A new study published in Psychological Science, a journal of the Association for Psychological Science, used identical and fraternal twins to look at the genetic and environmental influences underlying ADHD behaviors, reading, and math skills in children in an attempt to better understand the relationship among them. Sara Hart, of the Florida State University, and her colleagues used twins enrolled in a long-term study of reading and math. Hart says by focusing ...

Alexandria, VA – America has made great strides in recent years to reduce carbon emissions by increasing efficiency and turning to other, low or non-carbon energy sources. Meanwhile, carbon emissions in China have grown dramatically during that same time. EARTH looks at this disparity and asks the difficult questions about who is to blame when the coal China is burning is imported from "cleaner" countries and the emissions are produced to manufacture goods exported back to places with lower emissions. Learn more about this eye-opening subject in January's featured article ...

ORLANDO - A two-drug combination is safe and active in newly diagnosed acute myeloid leukemia and myelodysplastic syndrome patients who are usually excluded from clinical trials because they have other illnesses or poor performance status - a measure of disease progression - researchers reported this week at the 52nd American Society of Hematology Annual Meeting. "Our findings suggest current eligibility standards that prevent participation by these patients in phase I and phase II clinical trials might be inadequate," said Guillermo Garcia-Manero, M.D., professor in ...

Scientists have discovered how a network of repair proteins enables bacteria to prioritise the repair of the most heavily used regions of the DNA molecules that carry the instructions necessary for living cells to function. The research, carried out by academics at the University of Bristol and published in Molecular Cell (Dec. 2010), reveals that there are greater similarities between the DNA repair systems of bacteria and humans than had been suspected. When the chemical "letters" in a cell's DNA book of instructions are damaged the instructions become difficult ...

San Antonio - Metastatic breast cancer patients whose blood contains circulating tumor cells (CTCs) before or after treatment with high-dose chemotherapy and blood stem cell transplant have shorter survival periods, according to a new study by researchers at The University of Texas MD Anderson Cancer Center in Houston. The findings were presented today in a poster session at the 33rd Annual CTRC-AACR San Antonio Breast Cancer Symposium. In addition, patients with higher percentages of epithelial cells, or the presence of a specific cellular transition, had higher chances ...

PITTSBURGH— Nonchemical treatment systems are touted as environmentally conscious stand-ins for such chemicals as chlorine when it comes to cleaning the water-based air-conditioning systems found in many large buildings. But a recent study by University of Pittsburgh researchers suggests that this diverse class of water-treatment devices may be ineffective and can allow dangerous bacteria to flourish in the cooling systems of hospitals, commercial offices, and other water-cooled buildings almost as much as they do in untreated water. The two-year study by a team in Pitt's ...

DALLAS – Dec. 10, 2010 – It's a medical Catch-22: carotid artery surgery can itself cause stroke, but so can asymptomatic carotid disease if left untreated. UT Southwestern Medical Center researchers have now developed a clinical risk prediction rule using factors such as sex, race and health history to assess the danger the surgery poses, while a modified version will help patients make a more fully informed choice about whether to have the procedure. "It may take a thief to catch a thief, but physicians don't want to cause stroke while trying to prevent stroke, so ...

GALVESTON, Texas — "You'll be back on your feet in no time" is a phrase familiar to anyone who's ever had to spend time in a hospital. Now, a new study has shown that hospitalized elderly patients who literally "get back on their feet" by taking even short walks around a hospital unit tend to leave the hospital sooner than their more sedentary peers. Conducted at the University of Texas Medical Branch at Galveston and described in a paper appearing in the current issue of Archives of Internal Medicine, the study draws on data collected from 162 hospitalized patients over ...

It is estimated that 38 million people worldwide are currently infected with HIV and that 4.1 million more are added each year. For scientists to design treatment therapies that are effective over the long-term it is essential to learn more about how the virus mutates and develops resistance to medications. New, groundbreaking research by University of Victoria biomedical engineer Stephanie Willerth has significantly advanced the understanding of HIV and how to treat it. "The virus mutates at a very high rate which is very problematic for HIV patients because the virus ...

(Washington, DC) – A recent study of the use of metaphors in spoken language and various sign languages shows that certain types of metaphors are difficult to convey in sign language.
