Scientists said Tuesday they had manufactured a lightweight and reusable material that can absorb up to 33 times its weight in certain chemicals—a possible new tool against water pollution. http://phys.org/news286548569.html Nanotechnology Tue, 30 Apr 2013 14:00:01 EST news286548569 Researchers from the University of Gothenburg, Sweden, spend August in Sisimiut on the west coast of Greenland studying the prevalence of antibiotic resistance and the effects of antibiotic emissions on communities of bacteria living in marine sediments. More specifically, they were investigating how communities of bacteria in sediment and clay on the seabed are affected by exposure to antibiotics. http://phys.org/news269519650.html Space & Earth Mon, 15 Oct 2012 11:34:15 EST news269519650 Harvard-led researchers have discovered that an Ascomycete fungus that is common in polluted water produces environmentally important minerals during asexual reproduction. http://phys.org/news261655739.html Biology Mon, 16 Jul 2012 15:00:01 EST news261655739 Research is urgently needed to evaluate the risks and benefits of nano-pesticides to human and environmental health. Melanie Kah and Thilo Hofmann from the Department of Environmental Geosciences of the University of Vienna recently performed an extensive analysis of this emerging field of research. The results were published June 6th in the internationally recognized journal Critical Reviews in Environmental Science and Technology. The study presents the current scientific state of art on nano-pesticides and identifies direction priorities for future research. http://phys.org/news259405600.html Nanotechnology Wed, 20 Jun 2012 10:07:51 EST news259405600 Scientists in Poland have discovered that it is easy to clean and treat polluted water for extraction of valuable chemicals, such as those used in the production of drugs. The upshot of this is that the use of neither plants nor factories is required; only the Sun and a 'magic' powder are needed to get the job done. The study is presented in the journal Bioresource Technology. http://phys.org/news249301700.html Chemistry Fri, 24 Feb 2012 10:28:28 EST news249301700 Nanotechnology has developed tremendously in the past decade and was able to create many new materials with a vast range of potential applications. Carbon nanotubes are an example of these new materials and consist of cylindrical molecules of carbon with diameters of a few nanometers – one nanometer is one millionth of a millimeter. Carbon nanotubes possess exceptional electronic, mechanical and chemical properties, for example they can be used to clean polluted water. Scientists of the University of Vienna had recently published this new research in Environmental Science & Technology. http://phys.org/news230465237.html Nanotechnology Thu, 21 Jul 2011 11:07:32 EST news230465237 (PhysOrg.com) -- Imagine that you’re a grass shrimp. Now, imagine that you’re a rational grass shrimp, and that you have a choice of living in an environment with relatively high levels of dioxin, poly-chlorinated biphenyls (PCBs), and other floating nastiness or a relatively unpolluted environment with clean water and plenty of food.  http://phys.org/news226920022.html Biology Fri, 10 Jun 2011 10:21:06 EST news226920022 Pharmaceuticals, illicit drugs, shampoo, toothpaste, pesticides, chemical run-off from highways and many other pollutants infiltrate the giant aquifer under Mexico's "Riviera Maya," research shows. http://phys.org/news216222174.html Space & Earth Sun, 06 Feb 2011 13:44:19 EST news216222174 (PhysOrg.com) -- It is an annual rite of summer in Chicago: heavy or persistent rain causes a water backup from runoff and sewage that pollutes Lake Michigan, forcing officials to close beaches as a health precaution. http://phys.org/news213469916.html Space & Earth Wed, 05 Jan 2011 17:12:54 EST news213469916 The United States Army has taken delivery of the first two units of a "revolutionary" waste-water treatment system that will clean putrid water within 24 hours and leave no toxic by-products, according to scientists at Sam Houston State University. http://phys.org/news184945575.html Technology Tue, 09 Feb 2010 14:10:01 EST news184945575 (PhysOrg.com) -- A new sponge-like material that is black, brittle and freeze-dried (just like the ice cream astronauts eat) can pull off some pretty impressive feats. Designed by Northwestern University chemists, it can remove mercury from polluted water, easily separate hydrogen from other gases and, perhaps most impressive of all, is a more effective catalyst than the one currently used to pull sulfur out of crude oil. http://phys.org/news162572894.html Chemistry Tue, 26 May 2009 16:08:54 EST news162572894 A new sponge-like material that is black, brittle and freeze-dried (just like the ice cream astronauts eat) can pull off some pretty impressive feats.
