Rain showers may be caused by vortices in the air
The Delft researchers calculated how hundreds of thousands of water droplets contained in about one litre of cloud move and grow. During this process, it would seem that tubular-shaped vortices a few centimetres in size are formed and that these force the droplets outwards by centrifugal force, so that they congregate at the edge. For rain to be... view more... (1999-11-09)
A warmer world might not be a wetter one
A NASA study is offering new insight into how the Earth's water cycle might be influenced by global change. view more (2005-10-17)
NASA Scientists Detect Spectrum of Planets Orbiting Other Stars
For the first time, scientists at Goddard have obtained a spectrum, or molecular fingerprint, of a planet orbiting another star. Using spectroscopy, scientists were able to identify silicon dust in clouds on a gas-giant planet called HD 209458b. That planet is located 150 light years from Earth. view more (2007-02-23)
Diabetes treatment may lie in helping muscles to burn fat better
Scientists in Sydney and Melbourne have produced results that could silence the current debate about exactly how fat molecules clog up muscle cells, making them less responsive to insulin. view more (2009-01-28)
Are comets at the origin of life on earth ?
For over 60 years now, the University of Liege Astrophysics and Geophysics Institute (IAGL) has been concerned with the study of comets. Again today, four of its researchers have just made a major discovery for the understanding of these celestial objects : a lot of extra heavy nitrogen detected in two comets suggests the presence of great... view more...

Water and sanitation key to health of infants in developing countries (pp 94, 112)
Research among households in Peru in this week's issue of THE LANCET highlights how healthy growth of infants in less-developed countries is directly related to water supply, water storage, and sanitation-children who grow up in households where these facilities are unavailable or of poor quality are more likely to experience diarrhoeal disease... view more...

Expedition discovers new sea current off African coast
Researchers on board the Pelagia, the research vessel belonging to the Netherlands Institute for Sea Research (NIOZ), have discovered an interesting rotational current in the sea off the coast of South Africa. Unlike previously identified 'Agulhas rings', this one, a cyclone, rotates clockwise. The water in the centre is also about 50 centimetres... view more... (2001-07-26)
Drought resistance explained
Much as adrenaline coursing through our veins drives our body's reactions to stress, the plant hormone abscisic acid (ABA) is behind plants' responses to stressful situations such as drought, but how it does so has been a mystery for years. view more (2009-11-10)
Using an activated-carbon filtering pitcher significantly reduces chemicals in tap water
A study conducted by Université Laval researchers concludes that using an activated-carbon filtering pitcher is the most effective way to reduce disinfection by-products in tap water. view more (2006-11-03)
Fresh-cut produce washing practices can minimize food-borne illness risks
Researchers at the United States Department of Agriculture (USDA) recently examined the safety and quality of "wash techniques" used in the production of packaged produce. view more (2007-12-07)
Cold storage solution for global warming?
Researchers from the University of Leicester and the British Geological Society (BGS) have proposed storing CO2 in huge underground reservoirs as a way of reducing emissions- and have even identified sites in Western Europe that would be suitable. view more (2007-02-07)
Nano machine of the future captures great scientist's bold vision
An idea conceived by one of the world's greatest scientists nearly 150 years ago has finally been realised with a tiny machine that could eventually lead to lasers moving objects remotely. view more (2007-02-02)
Water flows like molasses on the nanoscale
A Georgia Tech research team has discovered that water exhibits very different properties when it is confined to channels less than two nanometers wide - behaving much like a viscous fluid with a viscosity approaching that of molasses. view more (2007-04-25)
Gold nanoparticles prove to be hot stuff
Gold nanoparticles are highly efficient and sensitive "handles" for biological molecules being manipulated and tracked by lasers, but they also can heat up fast-by tens of degrees in just a few nanoseconds-which could either damage the molecules or help study them. view more (2006-09-01)
'Air shower' set to cut water use by 30 per cent
As Australians become increasingly alert to the importance of using water wisely in the home, CSIRO researchers have found a way to use a third less water when you shower - by adding air. view more (2006-11-10)
Using Carbon Nanotubes For Quantum Computing
The computing community for many years has longed to be able to to carry out high speed calculations using a genuine Quantum Computer because it would facilitate the practical factorisation of very large numbers and the searching of unordered lists and databases. The rapid breaking of secure codes based on prime numbers would have a lot of... view more... (2004-07-15)
When proteins, antibodies and other biological molecules kiss, a new kind of biosensor can tell
When biological molecules kiss, a new kind of biosensor can tell. A new and deceptively simple technique has been developed by chemists at Vanderbilt University that can measure the interactions between free-floating, unlabeled biological molecules including proteins, sugars, antibodies, DNA and RNA. view more (2007-09-21)
Arecibo telescope finds critical ingredients for the soup of life in a galaxy far, far away
Astronomers from Arecibo Observatory radio telescope in Arecibo, Puerto Rico, have detected for the first time the molecules methanimine and hydrogen cyanide - two ingredients that build life-forming amino acids - in a galaxy some 250 million light years away. view more (2008-01-15)
Inactivity of proteins behind longer shelf life when freezing
Frozen biological material, for example food, can be kept for a long time without perishing. A study by researchers at the University of Gothenburg, Sweden, is close to providing answers as to why. view more (2009-03-03)
Astronomers hunt Martian water from Earth
As Mars makes its closest approach in almost 60,000 years, two Australian astronomers have used the United Kingdom Infrared Telescope (UKIRT) in Hawaii to look for signs that the planet once had liquid water - and so may have hosted life. Dr. Jeremy Bailey of the Anglo-Australian Observatory and the Australian Centre for Astrobiology (ACA) at... view more... (2003-08-26)
