Exposure shortly after birth to ambient metals from residential heating oil combustion and particles from diesel emissions are associated with respiratory symptoms in young inner city children, according to a new study by researchers at the Columbia Center for Children's Environmental Health (CCCEH) at Columbia University's Mailman School of Public Health. The study is the first to analyze the effects of exposure to airborne metals in this very young population and the findings could have important public health implications. http://www.physorg.com/news178204336.html Medicine & Health Mon, 23 Nov 2009 13:50:02 EST news178204336 Scientists are reporting evidence that air pollution - a well-recognized problem at major airports - may pose an important but largely overlooked health concern for people living near smaller regional airports. Those airports are becoming an increasingly important component of global air transport systems. The study, one of only a handful to examine airborne pollutants near regional airports, suggests that officials should pay closer attention to these overlooked emissions, which could cause health problems for local residents. It appears online in ACS' Environmental Science & Technology. http://www.physorg.com/news177772475.html Space & Earth Wed, 18 Nov 2009 14:40:03 EST news177772475 Immunologists at the University of Pittsburgh School of Medicine and Children's Hospital of Pittsburgh of UPMC and the have found a unique quirk in the way the immune system fends off bacteria called Francisella tularensis, which could lead to vaccines that are better able to prevent tularemia infection of the lungs. Their findings were published today in the early, online version of Immunity. http://www.physorg.com/news175435565.html Medicine & Health Thu, 22 Oct 2009 13:07:03 EST news175435565 Imagine a polka-dotted postage stamp-sized sensor that can sniff out some known poisonous gases and toxins and show the results simply by changing colors. http://www.physorg.com/news172072165.html Chemistry Sun, 13 Sep 2009 14:49:59 EST news172072165 The first dry powder inhalable vaccine for measles is moving toward clinical trials next year in India, where the disease still sickens millions of infants and children and kills almost 200,000 annually, according to a report presented here today at the 238th National Meeting of the American Chemical Society (ACS). http://www.physorg.com/news169656057.html Medicine & Health Sun, 16 Aug 2009 15:41:30 EST news169656057 Researchers at the National Institute of Standards and Technology have developed a new calibration technique that will improve the reliability and stability of one of NIST's most versatile technologies, the microhotplate. The novel NIST device is being developed as the foundation for miniature yet highly accurate gas sensors that can detect chemical and biological agents, industrial leaks and even signs of extraterrestrial life from aboard a planetary probe. http://www.physorg.com/news169227435.html Technology Tue, 11 Aug 2009 16:50:01 EST news169227435 Stephania Cormier, PhD, Associate Professor of Pharmacology at LSU Health Sciences Center New Orleans, has shown for the first time that early exposure to environmentally persistent free radicals (present in airborne ultrafine particulate matter) affects long-term lung function.
