Houston, TX – Women with a deleterious gene mutation are diagnosed with breast cancer almost eight years earlier than relatives of the previous generation who also had the disease and/or ovarian cancer, according to new research from The University of Texas MD Anderson Cancer Center. The findings, published online in Cancer and updated since first presented at the 2009 Breast Cancer Symposium, could have an impact on how women at highest risk for the disease are counseled and even screened in the future, explained Jennifer Litton, M.D., assistant professor in MD Anderson's ...

Researchers at USC were surprised recently to discover just how much the rising and setting of the sun drives life on Earth – even in unexpected places. Their findings, which appear this month in the Proceedings of the National Academy of Sciences, "speak volumes to the evolution of life on Earth," according to USC scientist Andrew Y. Gracey. "Everything is tied to the rotation of the planet," he said. In all organisms, a certain amount of gene expression (the process by which products are created from the blueprint contained in genes) is rhythmic. In creatures ...

Researchers at University Medical Center Utrecht, the Netherlands, have discovered a substance that has an adverse effect on nearly all types of chemotherapy - making cancer cells insensitive to the treatment. Chemotherapy often loses effectiveness over time. It is often unclear how or why this happens. It now appears that chemotherapy is made ineffective by two types of fatty acid that are made by stem cells in the blood. Under the influence of cisplatin chemotherapy, the stem cells secrete these fatty acids that induce resistance to a broad spectrum of chemotherapies. ...

EAST LANSING, Mich. --- When countries try to work together to limit the effects of climate change, the fear of being the only nation reducing greenhouse gas emissions – while the others enjoy the benefits with no sacrifice – can bring cooperation to a grinding halt. In a commentary in the Early Edition of the Proceedings of the National Academy of Sciences, Thomas Dietz, professor of sociology and environmental science and policy and assistant vice president for environmental research at MSU, and Jinhua Zhao, director of the MSU Environmental Science and Policy Program ...

Researchers from Mount Sinai School of Medicine have for the first time used several imaging techniques to prove the efficacy of a promising new treatment for atherosclerosis—the build-up of plaque in artery walls that can lead to a heart attack. Using positron-emission tomography (PET)/computed tomography (CT) and magnetic resonance imaging (MRI), the research team showed that dalcetrapib, a novel treatment for atherosclerosis, prevented the progression of disease and reduced vascular inflammation over 24 months. The data are published in the September 12 issue of The ...

EVANSTON, Ill. --- A new Northwestern University study provides compelling evidence that human males are biologically wired to care for their offspring, conclusively showing for the first time that fatherhood lowers a man's testosterone levels. The effect is consistent with what is observed in many other species in which males help take care of dependent offspring. Testosterone boosts behaviors and other traits that help a male compete for a mate. After they succeed and become fathers, "mating-related" activities may conflict with the responsibilities of fatherhood, ...

Young children who watch fast-paced, fantastical television shows may become handicapped in their readiness for learning, according to a new University of Virginia study published in the October issue of the journal Pediatrics. U.Va. psychologists tested 4-year-old children immediately after they had watched nine minutes of the popular show "SpongeBob SquarePants" and found that their executive function – the ability to pay attention, solve problems and moderate behavior – had been severely compromised when compared to 4-year-olds who had either watched nine minutes of ...

Monmouth Junction, NJ (September 12, 2011): A new study finds that infections following cardiac device implantations or replacement result in extremely high costs, both financially and in terms of patient mortality, even months after affected patients return home. Infections associated with pacemakers and defibrillators led to 4.8 to 7.7-fold increases in admission mortality, 1.6 to 2.1-fold increases long term mortality, 2.5 to 4.0-fold increases in hospital length of stay, and 1.4 to 1.8-fold increases in cost compared to pacemaker and defibrillator implantations without ...

According to a study published this week in the September/October 2011 issue of the American Journal of Health Promotion (Vol. 26, No. 1, pp. 56-60), people with consistently high health care costs experienced a 28 percent cumulative decrease in physician fees after an average of five years practicing the stress-reducing Transcendental Meditation technique compared with their baseline. Both between and within group comparisons were statistically significant. This study has major policy implications. In most populations, a small fraction of people account for the majority ...

CAMBRIDGE, Mass. -- An airplane's digital flight-data recorder, or "black box," holds massive amounts of data, documenting the performance of engines, cockpit controls, hydraulic equipment and GPS systems, typically at regular one-second intervals throughout a flight. Inspectors use such data to reconstruct the final moments of an accident, looking for telltale defects that may explain a crash. More recently, analysts have probed black-box data in an effort to prevent such accidents from ever occurring. Using software tools that can rapidly search data, operators can ...

Among the many ways that participation in Alcoholics Anonymous (AA) helps its members stay sober, two appear to be most important – spending more time with individuals who support efforts towards sobriety and increased confidence in the ability to maintain abstinence in social situations. In a paper that will appear in the journal Addiction and has been released online, researchers report the first study to examine the relative importance to successful recovery of the behavior changes associated with participation in AA. "AA is the most commonly sought source of help ...
