Every school day, more than 5 million students in the United States attend lessons held in modular classrooms. With new carpeting and paint, metal roofs and noisy ventilation systems, they can be a health hazard and make it harder for students to learn. http://www.physorg.com/news177775806.html Medicine & Health Wed, 18 Nov 2009 14:11:28 EST news177775806 Carbon nanotubes have made a meteoric career in the past 15 years, even if their applications are still limited. Recent research results show that - apart from their favorable mechanical and electrical properties - they also have disadvantageous characteristics. http://www.physorg.com/news160726972.html Nanotechnology Tue, 05 May 2009 07:23:41 EST news160726972 Scientists at Singapore's Institute of Bioengineering and Nanotechnology (IBN) have succeeded in unlocking the potential of carbon dioxide - a common greenhouse gas - by converting it into a more useful product. http://www.physorg.com/news159098987.html Chemistry Thu, 16 Apr 2009 11:10:21 EST news159098987 Byproducts from the electronics, fuel, chemical and defense industries can be far from benign. Toxic heavy metals like cadmium and lead can seep into our food chain and cause cancer. And if found in the soil, these dangerous materials can render parks off-limits and real estate worthless. http://www.physorg.com/news158851087.html Chemistry Mon, 13 Apr 2009 14:19:35 EST news158851087 After ignoring its own research for most of the last decade, the U.S. Environmental Protection Agency this spring will test the air outside dozens of schools across the nation that are close to industrial polluters. http://www.physorg.com/news158346416.html Space & Earth Tue, 07 Apr 2009 18:07:24 EST news158346416 Quantum dots have the potential to bring many good things into the world: efficient solar power, targeted gene and drug delivery, solid-state lighting and advances in biomedical imaging among them. http://www.physorg.com/news152797334.html Nanotechnology Mon, 02 Feb 2009 11:42:35 EST news152797334 (PhysOrg.com) -- Through work originally designed to remove contaminants from soil, scientists at the U.S. Department of Energy's Brookhaven National Laboratory and their Belgium colleagues at Hasselt University have identified plant-associated microbes that can improve plant growth on marginal land. The findings, published in the February 1, 2009 issue of Applied and Environmental Microbiology, may help scientists design strategies for sustainable biofuel production that do not use food crops or agricultural land. http://www.physorg.com/news152191745.html Biology Mon, 26 Jan 2009 11:29:29 EST news152191745 New research, reported this week in the online early edition of the Proceedings of the National Academy of Sciences, finds that coal burning, primarily in North America and Europe, contaminated the Arctic and potentially affected human health and ecosystems in and around Earth's polar regions. http://www.physorg.com/news138373476.html Space & Earth Tue, 19 Aug 2008 14:04:36 EST news138373476
