European Water Directive: Optical sensors detect minute amounts of pollutants
Minute amounts of organic pollutants-including oestrone-can now be detected in river water as a result of a new optical sensing instrument realised in a project funded by the EU's Environment Programme. view more (2004-09-01)
Energy efficient sewage plants
High-rate digestion with microfiltration is state-of-the-art in large sewage plants. It effectively removes accumulated sludge and produces biogas to generate energy. A study now reveals that even small plants can benefit from this process. view more (2009-08-14)
Sandia researchers develop unique 'surfactant' material
A unique class of materials developed by researchers at Sandia National Laboratories in Livermore, Calif., may prove useful in textile manufacturing, biomedical diagnostics, and other applications requiring the modification of surface properties of liquids or solids. view more (2005-06-08)
UCR environmental scientists propose chemical solution to cleaning California's Salton Sea
UC Riverside scientists are able to improve water quality by 90 percent in the rivers flowing into the Salton Sea, the largest lake in California, by using two kinds of water-treatment chemicals that remove phosphorus and silt from the river water. view more (2005-11-04)
Aussie arsenic-eating bacteria may save lives and clean mines
Melbourne scientists plan to harness the strange appetite of newly discovered Australian bacteria to help purify arsenic-contaminated water. The research group, led by microbiologist Dr Joanne Santini of La Trobe University, is working out how to use bacteria that eat arsenic to clean up contaminated wastewater in Australian and overseas mining... view more...

Up-and-coming researchers in life sciences
Fungal infections pose a serious threat to patients with weakened immune systems. In the past few years, candida albicans has become the most common germ for mycosis - and the number of cases is on the rise. This widespread member of the yeast family, has already developed strong resistance to antimycotic drugs commonly prescribed. Medication... view more... (2002-11-14)
Microbes Churn Out Hydrogen at Record Rate
By adding a few modifications to their successful wastewater fuel cell, researchers have coaxed common bacteria to produce hydrogen in a new, efficient way. view more (2007-11-14)
GROWing the next generation of water recycling plants
A vegetated rooftop recycling system has been developed that allows water to be used twice before it is flushed into the communal waste water system. view more (2005-12-09)
Drug used to treat skin conditions is a marine pollutant
Clotrimazole is a common ingredient in over-the-counter skin creams. Recent results from the University of Gothenburg, Sweden, now show that it is associated with major environmental risks. view more (2009-03-24)
Denitrification, its importance once diluted, may be back on top, Princeton-led team says
After more than a decade of inquiry, a Princeton-led team of scientists has turned the tables on a long-standing controversy to re-establish an old truth about nitrogen mixing in the oceans. view more (2009-09-03)
Pointing a finger at the source of fecal bacteria
Excessive levels of fecal bacteria were to blame for almost 60 percent of Nebraska streams deemed impaired by federal and state environmental laws in 2004. view more (2007-05-24)
Iowa State researchers explore turning fuel ethanol into beverage alcohol
Fuel ethanol could be cheaply and quickly converted into the purer, cleaner alcohol that goes into alcoholic drinks, cough medicines, mouth washes and other products requiring food-grade alcohol, say Iowa State University researchers. view more (2006-08-28)
Expert to Discuss Phosphorus' Impact on Gulf 'Dead Zone'
Phosphorus is an essential element in production agriculture, however fertilizer runoff and wastewater discharge have led to massive eutrophication problems in water bodies worldwide. view more (2009-10-29)
Glowing Results-Pitt Researchers Use Fluorescence to Develop Fast, Simple Method for Detecting Mercury in Fish and Dental Fillings
Researchers at the University of Pittsburgh have developed a simple and quick method for detecting mercury in fish and dental samples, two substances at the center of public concern about mercury contamination. view more (2008-11-19)
Even a Mile of Forest Makes a Difference in Water Quality
Results from a small-scale experiment in western North Carolina illustrate the importance of National Forest lands in ensuring high water quality in the Southern Appalachian region. view more (2006-01-31)
Innovative Biotechnology Projects Secure Share Of £1m DTI Funding Stream
New cost effective and environmentally friendly ways of treating wastewater in the paper and textiles industries are among five projects to share almost £1 million in government funding, Science Minister Lord Sainsbury announced today. The projects are part of the Department of Trade and Industry's BIO-WISE Programme, which encourages UK... view more... (2002-04-25)
Chronicle of Martian Expedition
A man is the most vulnerable chain in long-term space expedition. How numerous should a crew be? What are the principles of a crew selection? What should be made to protect people during a flight and on some other planet? Scientists from the Institute for Problems of Medicine and Biology are trying to answer these and many other questions. With... view more... (2001-04-20)
Two bacteria better than one in cellulose-fed fuel cell
No currently known bacteria that allow termites and cows to digest cellulose, can power a microbial fuel cell and those bacteria that can produce electrical current cannot eat cellulose. view more (2007-07-30)
Space technology disposes of sludge
Research funded by the European Space Agency into ways of feeding future astronauts on missions to Mars is about to find a very down-to-earth application - how to dispose of the sewage sludge left over after wastewater treatment. The MELISSA (Micro-Ecological Life Support Alternative) project, which ESA is funding in companies and research... view more... (2002-05-15)
