Small amounts of oil leave a fluorescent sheen on polluted water. Oil sheen is hard to remove, even when the water is aerated with ozone or filtered through sand. Now, a University of Utah engineer has developed an inexpensive new method to remove oil sheen by repeatedly pressurizing and depressurizing ozone gas, creating microscopic bubbles that attack the oil so it can be removed by sand filters. http://www.physorg.com/news177572736.html Chemistry Mon, 16 Nov 2009 05:46:54 EST news177572736 (PhysOrg.com) -- NASA scientists studying the origin of life have reproduced uracil, a key component of our hereditary material, in the laboratory. http://www.physorg.com/news176721370.html Chemistry Fri, 06 Nov 2009 09:17:43 EST news176721370 Contaminants from natural coal deposits in the Gulf of Alaska are not easily bioavailable, unlike the crude oil from the Exxon Valdez tanker catastrophe. This clearly disproves the theory that natural coal deposits were the cause of observed environmental damage. PAH pollutants were blamed for the continuing degradation of the ecosystem off the coast of Alaska. Then a dispute erupted over the origins of these pollutants in science. According to an international team of researchers writing in specialist journal Environmental Science & Technology, the crude oil from the Exxon Valdez was the main source of the bioavailable PAH contaminants. http://www.physorg.com/news170937855.html Space & Earth Mon, 31 Aug 2009 11:45:17 EST news170937855 Attention all smokeless tobacco users! It's time to banish the comforting notion that snuff and chewing tobacco are safe because they don't burn and produce inhalable smoke like cigarettes. A study that looked beyond the well-researched tobacco hazards, nitrosamines and nicotine, has discovered a single pinch -- the amount in a portion -- of smokeless tobacco exposes the user to the same amount of another group of dangerous chemicals as the smoke of five cigarettes. http://www.physorg.com/news169644304.html Chemistry Sun, 16 Aug 2009 12:40:01 EST news169644304 For many people, summer festivities would be terribly un-festive without the sizzle, the smoke, and the tantalizing smell of meat being barbecued. In the summer, many gatherings revolve around the grill, and there are shelves of cookbooks devoted to the art of cooking over an open flame. http://www.physorg.com/news166980202.html Medicine & Health Thu, 16 Jul 2009 17:10:04 EST news166980202 While cancer touches the lives of many humans, it is also a major threat to wild animal populations as well, according to a recent study by the Wildlife Conservation Society (WCS). http://www.physorg.com/news165058422.html Biology Wed, 24 Jun 2009 10:34:24 EST news165058422 Micro-organisms occurring naturally in coastal mudflats have an essential role to play in cleaning up pollution by breaking down petrochemical residues. Research by Dr Efe Aganbi and colleagues from the University of Essex, presented at the Society for General Microbiology's meeting at Harrogate today (Monday 30 April), reveals essential differences in the speed of degradation of the chemicals depending on whether or not oxygen is present. http://www.physorg.com/news157616643.html Biology Mon, 30 Mar 2009 07:25:44 EST news157616643 Children born in areas with increased traffic-related pollution may be at greater risk of developing asthma due to genetic changes acquired in the womb, according to new research from the University of Cincinnati (UC) and Columbia University Mailman School of Public Health.
