Crop Models Help Increase Yield per Unit of Water Used
Crop water use efficiency (WUE, or yield per unit of water used), also known as crop water productivity, can be improved through irrigation management and methods, including deficit irrigation (irrigating less than is required for maximum yields) and supplemental irrigation (irrigating to supplement precipitation so as to avoid crop failure or... view more...

The Romans preferred small-scale solutions to aqueducts and sewers
Contrary to common opinion, the Romans had several systems for the supply and drainage of water. The Romans preferred small-scale provisions such as cesspits, wells and rainwater tanks. The residents only constructed a water supply network or a sewerage system if these were not effective. Research carried out at the University of Nijmegen reveals... view more... (2002-06-24)
Flower power
A plastic "energy flower'' that collects solar and wind energy that can then be used to power appliances in the home for free has won a Northumbria University student a top award. Paul Richardson, a third year design student, won a £1,750 Design International Attachment Award from the RSA (Royal Society for the encouragement of Arts,... view more... (2002-05-24)
Water, water, everywhere - CMD19/CMMP with The Physics Congress 2002
Over half our planet is covered in water, and life cannot exist without it. But despite how common and important it is, surprisingly little is known about the structure of water, especially when it is next to other materials. A detailed understanding of how water behaves would not only reveal how biomolecules assemble or function - and possibly... view more... (2002-03-26)
Bran filters chlorinated hydrocarbons and arsenic out of waste water
Compounds of arsenic and hexachlorocyclahexane (HCHs) previously occurred above all in the production of pesticides. Pesticides containing HCHs have been prohibited in Germany since the 1980s. Arsenic is still used in the semiconductor and glass industries and pollutes water and the soil in many places. Since HCHs and arsenic are carcinogenic... view more... (2002-10-11)
Rocky water source
Gypsum, a rocky mineral is abundant in desert regions where fresh water is usually in very short supply but oil and gas fields are common view more (2008-06-12)
Disposable sensor uses DNA to detect hazardous uranium ions
Researchers at the University of Illinois at Urbana-Champaign have developed a simple, disposable sensor for detecting hazardous uranium ions, with sensitivity that rivals the performance of much more sophisticated laboratory instruments. view more (2007-02-15)
Wastewater produces electricity and desalinates water
A process that cleans wastewater and generates electricity can also remove 90 percent of salt from brackish water or seawater, according to an international team of researchers from China and the U.S. view more (2009-08-07)
Nanotech: A regulatory blueprint for the next administration
Nanotechnology will significantly change virtually every facet of the way we live. The next president has the opportunity to shape these changes and to ensure that nanotechnology's benefits will be maximized and its risks identified and controlled. view more (2008-07-23)
Nutrients in water may be a bonus for agriculture
Agriculture producers may find they don't have to bottle their water from the Seymour Aquifer in the Rolling Plains to make it more valuable, according to Texas AgriLife Research scientists. view more (2008-11-25)
Study shows more corn for biofuels would hurt water
More of the fertilizers and pesticides used to grow corn would find their way into nearby water sources if ethanol demands lead to planting more acres in corn, according to a Purdue University study. view more (2009-09-29)
Laboratory Evaporator for Reformation Technology
The Institut für Mikrotechnik Mainz GmbH (IMM) has developed a compact evaporator as test reactor for liquids like water and methanol. The Laboratory Evaporator LEVP is to be used for test series for the production of different gas mixtures in reformation technology. Quick preheating, free vaporization of liquids and overheating take place in... view more... (2004-04-19)
Scientists investigate impact of climate change on India's monsoon season
Scientists at the University of Liverpool are investigating the anticipated effects of climate change on India's monsoon season and the impact that alterations in India's water cycle will have on the country's people, agriculture and wildlife. view more (2007-03-09)
The retention of transition metals
Transition metals are essential for life but, depending on their concentration in the environment, they can prove to be toxic and provoke serious environmental impact. The aim of this PhD is to study the retention of transition metals by humic substances. Humic substances are, on the other hand, macromolecules arising from the physical, chemical... view more...

New Chlorine-Tolerant, Desalination Membrane Hopes to Boost Access to Clean Water
A chemical engineering professor at The University of Texas at Austin is part of a team that has developed a chlorine-tolerant membrane that should simplify the water desalination process, increasing access to fresh water and possibly reducing greenhouse gases. view more (2008-07-23)
Simple measures may prevent transmission of stomach ulcer bacteria
The stomach ulcer bacterium Helicobacter pylori is not transmitted through drinking water as previously thought, but rather through vomit and possibly faeces. view more (2009-06-25)
The memory lingers longer
PCBs and dieldrin, for example, now banned for further industrial and agricultural use, are simply not breaking down in the environment as speedily as needed to meet environmental targets. Catchments of rivers in west Yorkshire with a long history of contamination by chemicals used in the wool-processing industry show persistent levels of these... view more... (1999-12-22)
Archerfish tune their shots to universal properties of prey adhesion
Archerfish exhibit the remarkable ability to hunt for insects and other small terrestrial animals by firing precisely aimed streams of water that knock prey onto the water's surface. view more (2006-10-10)
Production of 'mint-scent'
In the industry, many tons of alcohol are used annually, as a starting point for the synthesis of many substances. Alcohol first has to be oxidised, after which aromas such as mint or cinnamon, or substances needed for the production of nylon are produced. Until now heavy metals such as chrome-oxide were used in the oxidation process. Ten Brink:... view more... (2000-03-03)
The origin of perennial water-ice at the South Pole of Mars
Thanks to data from ESA's Mars Express mission, combined with models of the Martian climate, scientists can now suggest how the orbit of Mars around the Sun affects the deposition of water ice at the Martian South Pole. view more (2007-07-16)
