New knowledge is making land-based smolt production more efficient and improving fish welfare in the process. Recirculation technology is solving the problem of access to an adequate supply of fresh water for additional fry production. http://phys.org/news289808806.html Biology Fri, 07 Jun 2013 07:50:01 EST news289808806 Scientists have long suspected that a flourishing of green foliage around the globe, observed since the early 1980s in satellite data, springs at least in part from the increasing concentration of carbon dioxide in Earth's atmosphere. Now, a study of arid regions around the globe finds that a carbon dioxide "fertilization effect" has, indeed, caused a gradual greening from 1982 to 2010. http://phys.org/news289215548.html Space & Earth Fri, 31 May 2013 10:39:20 EST news289215548 A new wonder material that can generate hydrogen, produce clean water and even create energy. http://phys.org/news282990979.html Chemistry Wed, 20 Mar 2013 09:36:37 EST news282990979 Research into water is growing faster than the average 4% annual growth rate for all research disciplines, claims a new report presented by Elsevier and Stockholm International Water Institute (SIWI) during the 2012 World Water Week in Stockholm. The report, "The Water and Food Nexus: Trends and Development of the Research Landscape" analysed the major trends in water and food-related article output at international, national and institutional levels. Elsevier and SIWI worked closely together on creating the report, which is based on the analysis of Scopus citation data by Elsevier's SciVal Analytics team. http://phys.org/news265282692.html Space & Earth Mon, 27 Aug 2012 10:38:20 EST news265282692 (Phys.org) -- By studying lakes and streams, limnologists are able to learn how water systems work which is vital in a world where human population increases cause such resources to become ever more valuable. Thus, any new source of reliable information that can add to the overall understanding of how such a system works can become invaluable over time. It is for this reason that a trio of researchers from the Center for Water Research and Anthropology and Sociology at the University of Western Australia, found themselves enlisting the help of local fishermen when studying Lake Como in the Italian Alps. In so doing, they found, as they describe in their paper published in the Proceedings of National Academy of Sciences, that knowledge fishermen gain both from their ancestors and through experience can be used to expand on scientific studies to provide a much more thorough analysis of a lake’s flow patterns. http://phys.org/news253266707.html Space & Earth Tue, 10 Apr 2012 08:52:02 EST news253266707 Plain, sloping roofs can collect up to 50% more rainwater than flat roofs with gravel. This water is also of higher quality. These are the conclusions of a study conducted by researchers from Autonomous University of Barcelona (UAB, Spain) which suggests the incorporation of systems to collect rainwater in urban planning. The water collected can be used to water streets and gardens, wash floors or vehicles and fill cisterns. http://phys.org/news238672555.html Space & Earth Mon, 24 Oct 2011 10:56:02 EST news238672555 Extreme events, such as floods or droughts, are caused by multiple factors - and must therefore be studied from many different perspectives. This is what international experts on water and climate research call for in the current issue of a renowned scientific journal. The Doctoral Program "Water Resource Systems", which is funded by the Austrian Science Fund FWF, is considered a precursor for interdisciplinary approach in this field. Thanks to the interactive education it offers, graduates from the program are able to solve complex problems facing water research. http://phys.org/news204811148.html Space & Earth Mon, 27 Sep 2010 12:59:28 EST news204811148 Scientists have discovered enormous plumes of oil in the deep waters of the Gulf of Mexico, in an indication that the leak from an underwater well could be far worse than previously estimated, The New York Times reported late Saturday. http://phys.org/news193193432.html Space & Earth Sun, 16 May 2010 02:00:01 EST news193193432
