NEW YORK, CAMBRIDGE, Mass., AND BOSTON (Feb. 9, 2011) -- For the first time, researchers have laid bare the full genetic blueprint of multiple prostate tumors, uncovering alterations that have never before been detected and offering a deep view of the genetic missteps that underlie the disease. The study, made possible by key advances in whole genome sequencing and analysis, points to several new prostate cancer genes and a critical category of genomic changes as important drivers of prostate cancer growth.

The enzyme that makes fireflies glow is lighting up the scientific path toward a long-sought new medical imaging agent to better monitor treatment with heparin, the blood thinner that millions of people take to prevent or treat blood clots, scientists are reporting. Their study appears in the ACS' monthly journal Bioconjugate Chemistry.
LEXINGTON, Ky. (Feb. 9, 2011) - The population of aged persons worldwide is expanding rapidly, and it is becoming increasingly clear that there are many different diseases that affect the minds of these individuals. Researchers at the University of Kentucky are breaking new ground in the ongoing project of identifying and defining those diseases most likely to affect an aged population. Dr.
The country where you live can have a big impact on your life. A new study of people from 128 countries finds that the more satisfied people are with their country, the better they feel about their lives—especially people who have low incomes or live in relatively poor countries.
Cultivating coca bushes, the source of cocaine, is speeding up destruction of rainforests in Colombia and threatening the region's "hotspots" of plant and animal diversity, scientists are reporting in a new study. The findings, which they say underscore the need for establishing larger protected areas to help preserve biodiversity, appear in ACS' journal Environmental Science & Technology.
Scientists are reporting discovery of an environmentally friendly way to make a key industrial material — used in products ranging from paints to diapers — from a renewable raw material without touching the traditional pricey and increasingly scarce petroleum-based starting material. Their report on a new catalyst for making acrylic acid appears in ACS Catalysis, the newest in the American Chemical Society's suite of 39 peer-reviewed scientific journals.
U.S. Department of Agriculture (USDA) scientist Pat Millner and safety manager David Prevar have worked with the U.S. Environmental Protection Agency (EPA) and private consultants to design and conduct a pilot study for an alternative way to cap landfills.
Millner is a microbiologist at the 6,615-acre Henry A. Wallace Beltsville Agricultural Research Center (BARC) operated in Beltsville, Md., by the Agricultural Research Service (ARS), the chief intramural scientific research agency of USDA.
Even if you drink diet soda — instead of the sugar variety — you could still have a much higher risk of vascular events compared to those who don't drink soda, according to research presented at the American Stroke Association's International Stroke Conference 2011.
In findings involving 2,564 people in the large, multi-ethnic Northern Manhattan Study (NOMAS), scientists said people who drank diet soda every day had a 61 percent higher risk of vascular events than those who reported no soda drinking.
Treating mild strokes with the clot-busting drug approved for severe stroke could reduce the number of patients left disabled and save $200 million a year in disability costs, according to a study presented at the American Stroke Association's International Stroke Conference 2011.
Tart cherries could help athletes reduce muscle damage to recover faster from a tough workout, according to new research published in the American College of Sports Medicine's journal Medicine & Science in Sports & Exercise.
Countries need to increase co-operation over conservation to protect birds and other wildlife in an era of climate change, according to a new continental-scale study.
Experts have established a new conservation index to help policy-makers to deal with the effects of climate change on birds in Africa, and it could assist governments across the world to protect wildlife areas and help species as climate change forces them to move to new areas.
The construction of new rail lines, or the relocation of old ones underground, has increased society's interest over recent years in the vibrations produced by trains, especially among people who live or work near the tracks. Now a study headed by the Polytechnic University of Valencia (UPV) has made it possible to estimate the trajectory of vibrations from the point at which they are generated (wheel-rail contact) through to the ground.
A systematic review of medical evidence has determined drug-eluting stents (DES) outperform bare metal stents (BMS) for revascularization of chronic total occlusions. Researchers found coated stents reduce restenosis and target revascularization, offering a safe approach with similar adverse events as BMS. Full findings are available in the February issue of Catheterization and Cardiovascular Interventions, a journal published by Wiley-Blackwell on behalf of The Society for Cardiovascular Angiography and Interventions.
BINGHAMTON, NY – Eight small teeth found in a cave near Rosh Haain, central Israel, are raising big questions about the earliest existence of humans and where we may have originated, says Binghamton University anthropologist Rolf Quam. Part of a team of international researchers led by Dr. Israel Hershovitz of Tel Aviv University, Qaum and his colleagues have been examining the dental discovery and recently published their joint findings in the American Journal of Physical Anthropology.
Researchers from the Hospital Virgen de las Nieves of the University of Granada have identified the most frequent mutations in the gene KCNH2 in patients with long QT syndrome.
Long Qt syndrome is a disorder of cardiac ionic channels that approximately affects one in every 2,500 people and may cause torsade de pointes episodes, which can trigger sudden death. This condition usually affects children and adolescents, and it is occasionally mistaken for convulsions, leading to a misdiagnosis of epilepsy.
