Los Angeles, CA (May 18, 2011) When people have power, they act the part. Powerful people smile less, interrupt others, and speak in a louder voice. When people do not respect the basic rules of social behavior, they lead others to believe that they have power, according to a study in the current Social Psychological and Personality Science (published by SAGE). People with power have a very different experience of the world than people without it. The powerful have fewer rules to follow, and they live in environments of money, knowledge and support. People without power ...

SEATTLE – Although chemotherapy is used to kill cancer cells, it can also have a strong toxic effect on normal cells such as bone marrow and blood cells, often limiting the ability to use and manage the chemotherapy treatment. Researchers at Fred Hutchinson Cancer Research Center reported at today's annual meeting of the American Society of Gene and Cell Therapy in Seattle that one possible approach to reduce this toxic effect on bone marrow cells is to modify the cells with a gene that makes them resistant to chemotherapy. Hans-Peter Kiem, M.D., a member of the Hutchinson ...

New research provides evidence for significant differences between new and old red blood cells used for transfusions and could provide a cheap, rapid and effective way to monitor the quality of blood supplies. Even with preservatives, blood stored in banks continues to age, resulting in biomaterials leaking from the red blood cells and subsequent changes to cell properties and function. There have been concerns raised worldwide about using older stored blood because of questions about various changes believed to affect the quality of the red blood cells. Currently, ...

Researchers from the King Juan Carlos University (URJC) have carried out a research study published in Biological Conservation, which looked at whether spiders were more tolerant of human impact than other animals. The answer was no: arachnids suffer the consequences of changes to their landscape just like any other animal. "The abundance and number of spider species is negatively affected by the impact of many human land uses, such as habitat fragmentation, fire and pesticides", Samuel Prieto-Benítez and Marcos Méndez, researchers at the URJC Biodiversity and Conservation ...

Known as the Compliance, Safety, Accountability program, the initiative focuses on identifying and sanctioning trucking companies with track records of risky driving in order to prevent future trucking accidents. The CSA program evaluates trucking companies and keeps track of individual drivers. But, even though individuals are monitored, gaps in the system may allow unsafe truckers to remain behind the wheel. The ...

Individuals who are treated for cancer during childhood have a significantly higher risk of developing gastrointestinal (GI) complications – from mild to severe – later in life, according to a study led by the University of California, San Francisco. The findings underscore the need for childhood cancer survivors and their physicians to be aware of these risk factors to ensure patients' ongoing health care needs are met. "We have, in a relatively short period of time, made remarkable progress in treating pediatric cancer, which has resulted in a growing population of ...

GALVESTON, Texas — No one knows the cause of most cases of Alzheimer's, Parkinson's and other neurodegenerative disorders. But researchers have found that certain factors are consistently associated with these debilitating conditions. One is DNA damage by reactive oxygen species, highly destructive molecules usually formed as a byproduct of cellular respiration. Another is the presence of excessive levels of copper and iron in regions of the brain associated with the particular disorder. University of Texas Medical Branch at Galveston researchers have discovered how ...

A proposed federal measure to improve motor vehicle safety will be delayed by nearly a year. The National Highway Traffic Safety Administration (NHTSA) was expected to publish a rule in late February of 2011 creating a phased-in requirement for backup cameras on cars and trucks sold in the U.S. But NHTSA recently requested another 45-day commentary period, and told Congress that the rule could be delayed by ten months. The rule will require that ten percent of new vehicles be equipped with backup cameras by September 2012, increasing to 40 percent a year later with full ...

Species pairs that disappear through hybridization after human-induced changes to the environment can reemerge if the disturbance is removed, according to a new mathematical model that shows the conditions under which reemergence might happen. The findings, published in the journal Evolution, are important for conservationists and ecosystem managers interested in preserving, or even restoring, systems that have been disturbed by human activity. By simulating environmental disturbances that reduce the ability of individuals to identify and select mates from their own ...

North American red foxes originated from two separate genetic lineages that were isolated from each other by glaciers some half a million years ago, according to a U.S. Forest Service Pacific Northwest Research Station study. The research—featured in the April/May 2011 issue of Science Findings, a monthly publication of the station—can assist efforts aimed at conserving potentially imperiled montane populations of the species. "When most people think of the red fox, they envision the ones that thrive in low-elevation, human-dominated landscapes," said Keith Aubry, ...

When patients entrust their health to physicians, surgeons and other health care professionals, they deserve to know the risks and expect a health care provider's best efforts to maximize the chance of a positive outcome. The fact is, many occurrences of surgical error, misdiagnosis, medication error or birth injury are preventable, and medical malpractice attorneys strive to help clients and surviving family members obtain justice when they suspect that standards were not followed. A patient's right to damages for the harm caused by medical errors is an established ...
