Late preterm births, or births that occur between 34 and 36 weeks (approximately 4 to 6 weeks before the mother's due date), account for more than 70% of preterm births. Despite the large number of affected babies, many people are unaware of the serious health problems related to late preterm births. A new study and an accompanying editorial soon to be published in The Journal of Pediatrics investigate the serious neurological problems associated with late preterm births. http://www.physorg.com/news148192562.html Medicine & Health Thu, 11 Dec 2008 04:36:02 EST news148192562 The United States must re-establish its global leadership in nuclear arms control while continuing to update its nuclear arsenal as necessary, but it should not add any new nuclear capabilities in the process, a joint working group of scientists and policy experts says in a study meant to inform decision making by the incoming Obama administration. http://www.physorg.com/news148132530.html Other Sciences Wed, 10 Dec 2008 11:55:30 EST news148132530 The economic cost of death due to cancer is high in the United States, regardless of whether researchers estimate the economic impact in lost work productivity or in a more global measure using the value of one year of life, according to two studies published online December 9 in the Journal of the National Cancer Institute. http://www.physorg.com/news148067483.html Medicine & Health Tue, 09 Dec 2008 17:51:23 EST news148067483 When it comes to the world of the very, very small - nanotechnology - Americans have a big problem: Nano and its capacity to alter the fundamentals of nature, it seems, are failing the moral litmus test of religion. http://www.physorg.com/news147881829.html Nanotechnology Sun, 07 Dec 2008 14:17:09 EST news147881829 Organizations in the United States that are at the highest risk of sustaining damage from climate change are not adapting enough to the dangers posed by rising temperatures, according to a Yale report. http://www.physorg.com/news147444502.html Space & Earth Tue, 02 Dec 2008 12:48:22 EST news147444502 Tufts researchers and colleagues report that place of birth plays a role in the occurrence of asthma in a United States black population.

The USEPA estimates that 6.3 million tonnes of Class B biosolids are generated in the United States each year, and that by 2010, the amount generated per year will increase to 7.4 million tonnes. Biosolids produced during municipal sewage treatment are most commonly applied to land as a fertilizer at agricultural sites throughout the United States. Class B biosolids, which are the principal type of biosolids applied to land, contain a variety of enteric pathogens. http://www.physorg.com/news144326545.html Space & Earth Mon, 27 Oct 2008 11:42:25 EST news144326545 People traveling to other countries to receive kidney transplants experience more severe post-transplant complications with a higher incidence of acute rejection and severe infections, according to a study appearing in the November 2008 issue of the Clinical Journal of the American Society Nephrology (CJASN).

Black Galaxy. Kashmir Gold. If you`ve remodeled your kitchen in the last decade, chances are you encountered one of the 1,600 varieties of granite imported into the United States from 64 different countries. According to recent market research, demand for natural stone countertops has increased 5 percent annually between 2001 and 2006, with granite being the most popular option. And why not? Granite is not only durable, resistant to mold and mildew, and easy to clean, but because no two pieces of granite are alike, your counter will have its own unique look. http://www.physorg.com/news142184239.html Other Sciences Thu, 02 Oct 2008 16:37:19 EST news142184239 Nearly 200 million people now live outside their country of birth. But the patterns of migration that got them there have proven difficult to project. Now scientists at Rockefeller University, with assistance from the United Nations, have developed a predictive model of worldwide population shifts that they say will provide better estimates of migration across international boundaries. Because countries use population projections to estimate local needs for jobs, schools, housing and health care, a more precise formula to describe how people move could lead to better use of resources and improved economic conditions. http://www.physorg.com/news141924745.html Other Sciences Mon, 29 Sep 2008 16:32:25 EST news141924745 Despite widespread concern about climate change, annual carbon dioxide emissions from burning fossil fuels and manufacturing cement have grown 38 percent since 1992, from 6.1 billion tons of carbon to 8.5 billion tons in 2007. http://www.physorg.com/news141489371.html Space & Earth Wed, 24 Sep 2008 15:36:11 EST news141489371 Nitrate is the most common chemical contaminant in the world's ground water, including in aquifers used for drinking-water supply. Nitrate in drinking water of the United States is regulated by the U.S. Environmental Protection Agency (USEPA) because of concerns related to infant health and possible cancer risks. Use of man-made synthetic fertilizers has steadily increased since World War II, raising the potential for increased nitrate contamination of the nation's ground water, despite efforts in recent decades to improve land-management practices. http://www.physorg.com/news140866907.html Space & Earth Wed, 17 Sep 2008 10:41:47 EST news140866907
