Fuzzy logic water quality
A fuzzy logic approach to analyzing water quality could help reduce the number of people in the developing world forced to drink polluted and diseased water for survival.   view more (2008-04-18)

Dartmouth study finds that arsenic inhibits DNA repair
Dartmouth researchers, working with scientists at the University of Arizona and at the Department of Natural Resources in Sonora, Mexico, have published a study on the impact of arsenic exposure on DNA damage.   view more (2006-05-30)

Sugar coupled to protein causes kidneys to save water
Several new mechanisms that are important for the production and transport of water channels to the cell surface of kidneys have been identified by a Dutch researcher. The water channels ensure that water in the body is reused. If these fail to work properly, you urinate too much and dehydrate. The... view more (2003-10-10)

Century of data shows intensification of water cycle but no increase in storms or floods
A review of the findings from more than 100 peer-reviewed studies shows that although many aspects of the global water cycle have intensified, including precipitation and evaporation, this trend has not consistently resulted in an increase in the frequency or intensity of tropical storms or floods... view more (2006-03-16)

Sandia, task force to study ways ocean and wastewater can be desalinized in California
Researchers from the National Nuclear Security Administration's Sandia National Laboratories, together with fellow members of the Joint Water Reuse & Desalination Task Force, in coming months will be studying the best ways to desalinize-and make potable-ocean water, subsurface brines, and... view more (2005-09-07)

Water at Martian south pole
Thanks to ESA's Mars Express, we now know that Mars has vast fields of perennial water ice, stretching out from the south pole of the Red Planet. Astronomers have known for years that Mars possessed polar ice caps, but early attempts at chemical analysis suggested only that the northern cap could... view more (2004-03-18)

Is tap water safe for expectant mothers?
Drinking water disinfected by chlorine while pregnant may increase the risk of having children with heart problems, cleft palate or major brain defects, according to a study published today in BioMed Central's open access journal Environmental Health.   view more (2008-06-03)

Pesticides Persist in Ground Water
Numerous studies over the past four decades have established that pesticides, which are typically applied at the land surface, can move downward through the unsaturated zone to reach the water table at detectable concentrations.   view more (2008-07-02)

Waddenzee fresher than ever
The seawater in the Waddenzee is becoming fresher. More river water is reaching the Waddenzee via the outlet sluices of the IJsselmeer Dam. This is the conclusion of Dr Hendrik van Aken from the Netherlands Institute for Sea Research. Along with the fresh water, more nitrate and phosphate are... view more (2002-09-11)

Gazelles shrink liver and heart to reduce oxygen consumption during drought
How do gazelles and other large desert mammals adjust their physiology to survive when food and water are in short supply?   view more (2006-06-09)

'Micro-boxes' of water used to study single molecules
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated the use of water droplets as minuscule "boxes" for small numbers of biomolecules.   view more (2006-07-24)

University of Ulster to Reveal Health of Northern Ireland`s Lakes and Rivers
Assessing the health of our rivers and lakes will be easier and much more accurate from now on - thanks to University of Ulster researchers. Dr Brian Rippey, from the Universities' School of Biological and Environmental Sciences, has come up with a new method of finding out what state Northern... view more (2002-04-25)

Mars Express has the sophisticated science to find the water ice on Mars
"The presence of such a large amount of water ice under Mars`s surface is very surprising. Especially so close to the surface!" says Gerhard Schwehm, Head of the Planetary Missions Division at ESA. The team working on ESA`s Mars Express, the next mission to the Red Planet, is thrilled by NASA`s... view more (2002-05-30)

University of Oregon researcher finds that on water's surface, nitric acid is not so tough
Nitric acid is a notoriously strong and chemically destructive compound found in water on earth and in our atmosphere. However, a team of researchers have found that its punch is much weaker when it sits on the top of a water surface.   view more (2007-08-21)

Bacteria and nanofilters - the future of clean water technology
Bacteria often get bad press, with those found in water often linked to illness and disease. But researchers at The University of Nottingham are using these tiny organisms alongside the very latest membrane filtration techniques to improve and refine water cleaning technology.   view more (2008-02-25)

A bug's life... in a bubble
Hundreds of insect species live mainly underwater, but how do they breathe? University of Alberta researcher Morris Flynn did a study to find out how these species are able to remain underwater without drowning.   view more (2008-08-11)

Controlling the movement of water through nanotube membranes
By fusing wet and dry nanotechnologies, researchers at Rensselaer Polytechnic Institute have found a way to control the flow of water through carbon nanotube membranes with an unprecedented level of precision.   view more (2007-02-14)

The Sun Flooded Europe
It will be easy to predict typhoon appearance if you know where it arises. One of the cyclone forming regions is the northern part of the Mediterranean along the French and Italian coast. Most of last summer cyclones came from there and flooded many European countries and Southern Russia, and even... view more (2002-10-25)

Glass fibre predicts uptake in earthworms
Dutch researchers have discovered that glass fibres absorb the same types and quantities of toxic substances from damp soils as earthworms, which form the basis of the current methods soil researchers use for toxicity analyses. The Institute for Inland Water Management and Waste Water Treatment... view more (2003-06-24)

Slow-frozen people? Latest research supports possibility of cyropreservation
The latest research on water—still one of the least understood of all liquids despite a century of intensive study — seems to support the possibility that cells, tissues and even the entire human body could be cyropreserved without formation of damaging ice crystals.   view more (2006-06-21)

Refined Petrol Stations
There are always oil spots near the petrol stations. Rainwater washes them away, polluting the environment. Researchers from Perm have developed a refining unit for cleaning rainwater sewage from petrol stations. It was successfully tested in Moscow and Perm. The unit base is a new filter -... view more (2002-02-19)

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... 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... 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... 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... view more (2002-10-11)
