Did comets flood Earth's oceans?
Did the Earth form with water locked into its rocks, which then gradually leaked out over millions of years? Or did the occasional impacting comet provide the Earth's oceans? The Ptolemy experiment on Rosetta may just find out"¦ The Earth needed a supply of water for its oceans, and the comets are large celestial icebergs - frozen... view more... (2004-06-16)
Paying peanuts for clean water
Peanut husks, one of the biggest food industry waste products, could be used to extract environmentally damaging copper ions from waste water, according to researchers in Turkey. view more (2007-11-08)
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)
Brain malfunction explains dehydration in elderly
As Australia faces another hot, dry summer, scientists from Melbourne's Howard Florey Institute have warned that elderly people are at risk of becoming dehydrated because their brains underestimate how much water they need to drink to rehydrate. view more (2007-12-18)
Surprising new water property discovered
At a microscopic level, water molecules behave rather like the needle of a compass. Just as the needle moves when surrounded by a magnetic field (such as that of the Earth), water molecules move slightly in one direction when there is an electric field. Or at least that is what physicists thought till now. Research at the Universitat... view more... (2004-05-13)
Warm water vibrates for longer
Dutch researcher Arjan Lock has investigated the behaviour of vibrating water molecules. Using ultra-short laser pulses, he found that hydrogen atoms in water molecules vibrate for longer at higher temperatures. This is abnormal because in the majority of substances a vibration lives shorter at higher temperatures. Lock studied the OH-stretch... view more... (2004-02-05)
Balancing Use to Fill Today`s Gaps and Meet Tomorrow`s Needs: Water for People, Food and Environment Stockholm Water Symposium in August is last major global water forum before UN development summit in South Africa
To feed the planet`s 8 billion inhabitants in 2025, the world will need as much extra water simply for food production as is currently in use for - but not yet satisfying - our drinking, sanitation, industrial and irrigation needs. From where will this new water come? That question will be explored August 12 - 15 by attendees at the 2002... view more... (2002-08-06)
Cleaning up pollutants with sunlight
A cheap, harmless chemical and sunlight could provide an environmentally friendly way of destroying micro-pollutants in the environment. UK researchers are developing a new type of reactor to destroy persistent contaminants such as pesticides and pharmaceutical residues. The technology, which breaks down the polluting molecules into carbon... view more... (2002-10-23)
Study of espresso coffee quality
The preparation of Espresso Coffee (EC) is influenced by factors related to the coffee and water and other technical conditions related to the machine. Susana Andueza has presented her doctoral thesis about Influence of technological variables on espresso coffee quality. Antioxidant and pro-oxidant capacity of coffee in the University of Navarre.... view more... (2004-02-12)
Beavers can help ease drought
They may be considered pests, but beaver can help mitigate the effects of drought, and because of that, their removal from wetlands to accommodate industrial, urban and agricultural demands should be avoided, according to a new University of Alberta study. view more (2008-02-21)
Nitrate Concentrations of Ground Water Increasing in Many Areas of the United States
Nitrate is the most common chemical contaminant in the world's ground water, including in aquifers used for drinking-water supply. view more (2008-09-18)
Climate change has surprising effect on endangered naked carp
Forthcoming in the January/February 2007 issue of Physiological and Biochemical Zoology, a groundbreaking study reveals an unanticipated way freshwater fish may respond to water diversion and climate change. view more (2006-12-20)
Changing climate will lead to devastating loss of phosphorus from soil
Crop growth, drinking water and recreational water sports could all be adversely affected if predicted changes in rainfall patterns over the coming years prove true, according to research published this month in Biology and Fertility of Soils. view more (2009-04-15)
TU Delft tests windmill for seawater desalination
A traditional windmill which drives a pump: that is the simple concept behind the combination of windmill/reverse osmosis developed by the Delft University of Technology (TU Delft) in The Netherlands. In this case, it involves a high-pressure pump which pushes water through a membrane using approximately 60 bar. This reverse osmosis membrane... view more... (2008-03-03)
Safe water? Lessons from Kazakhstan
Despite significant efforts to improve access to safe water and sanitation, a new report co-authored by an expert at The University of Nottingham, argues that much more needs to be done. view more (2008-04-30)
Naked turkey
WHAT`S the secret of great-tasting Christmas turkey? Let it get naked. Whipping the foil off a cooking turkey to allow the skin to brown induces a previously unrecognised process that concentrates the meat flavours at the surface. Chefs have always known that browning the bird with direct heat creates flavour. But more important than the heat,... view more... (2001-12-19)
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)
First "Café scientifique" in Moscow: Who drinks water from the faucet?
In the name of science 37 participants of the first café scientifique, held in Moscow at the end of April in the "Dark and Light" beer house on the Pokrovka in Moscow, drank 40 liters of beer. This café was the first of a series of five meetings that were planned for this year by the organizers of the café - the... view more... (2005-05-12)
Fluoridated water for Queensland ... at last
Griffith University's School of Dentistry and Oral Health welcomes the Queensland Government's decision to introduce fluoride into the public drinking water - a measure endorsed by all major international and Australian health bodies as the best way to prevent dental decay. view more (2007-12-07)
Water fluoridation still a cost-effective preventive measure
Teams of investigators from the University of Melbourne and New South Wales Health today reported the results of a project investigating the impact of changing dental needs on the cost savings from community water fluoridation in Melbourne, Australia. view more (2006-06-30)
