#Bubble, bubble, at the flick of a switch Boiling water, with its commotion of bubbles that rise from a surface as water comes to a boil,
is central to most electric power plants, heating and cooling systems, and desalination plants. Now, for the first time, researchers at MIT have found a way to control this process, literally with the flick of an electrical switch.
but these have required special fluids rather than water, and a thousandfold higher voltages, making them economically impractical for most uses.
The new feat was accomplished by adding surfactants to water essentially creating a soapy liquid. The surfactant molecules
the bubbles formed by boiling water also require nucleation. Tiny irregularities on a metal surface can provide those nucleation points,
#New company to produce water-disinfecting tablets invented at UVA A new University of Virginia-inspired public benefit company with a global health mission,
company officials announced at the 2015 Water and Health Conference, being held this week at the University of North carolina School of Global Public health.
The technology transfer company will produce ceramic water disinfection tablets called adidropsfor people in developing countries who have poor access to clean drinking water.
The company is an outgrowth of a project started in 2012 at UVA through a nonprofit organization called Puremadi. adiis the Tshivenda South african word for water.

#Nasa confirms water on Mars, increasing chance of alien life Mars has long been known as our barren sister planet but today,
NASA scientists have announced they have found flowing water on the red desert planet. NASA and the Nature Geoscience journal released their findings on a Live Stream announcement stating that the long,
dark streaks found on Mars are a telltale sign of still flowing water on the Martian surface.
NASA scientists theorize the liquid water runs down canyons and cater walls during the summer months on Mars. Eventually these dark streaks dry up as the planet's surface cools in autumn.
The only question is where does the water come from? Astrologists suggest it may originate from underground water contained in ice or salty aquifers.
Another likely theory could be the water condenses into a liquid from Mars'atmosphere. To this day, Earth is still the only planet in the known universe with liquid H2o on its surface
and so finding out flowing water once exists on Mars is huge. Beyond the geological discovery, dramatically increases our chances of finding extraterrestrial life.

and petroleum industries and is capable of sucking mercury out of both soil and water. The dark red polymer material is made using limonene,
the university says the material is"dirt cheap"to produce meaning it could easily be used in widespread applications like lining pipes for domestic and waste water, large-scale environmental cleanup operations and even for reducing mercury levels in large bodies of water like the oceans.
The researchers found that the material can also remove other toxic metals from water and it safely stores the pollutants until it can be removed.
'the research paper had been published in Water Science and Technology. The new technology uses the method called'pervaporation'for removal of salt from water with minimal power usage.
Under the process, the untreated water is filtered first though a membrane to remove larger particles.
The filtered water is then vapourised under heat as the second step for purification. The vapour is condensed thereafter to produce pure water for drinking purposes.
The filter which is made of cellulose acetate powder and other components, has been designed to bind the salt particles as they pass through the membrane.
Developed by University of Alexandria researchers Mona Naim, Mahmoud Elewa, Ahmed El-Shafei and Abeer Moneer,
The technology is effective for water having high saline content as well as for water contaminated with sewage and/or dirt,
and water purifiers. The idea is that every household item that needs to be replenished frequently will get its own dedicated Dash button.

Laboratory studies conducted in the University's School of Medical sciences have confirmed that changes in brain water channels over time play a critical role in traumatic brain injury.
For his Phd at the University researcher Dr Joshua Burton tested two compounds that alter the natural flow of water activity in and out of the brain.
The water channels normally function to protect the brain but in the case of traumatic injury or stroke they become a pathway of vulnerability that allows swelling.
Dr Burton has found that applying a drug that closes the water channels can inhibit initial water entry helping to close the window of vulnerability.
A second drug used later in the progression of the injury acts to enhance the water channel activity letting superfluous moisture out when needed.
This work builds on more than a decade of research conducted by the University of Adelaide's Professor Andrea Yool on the water channel proteins known as aquaporins.
This work also demonstrates for the first time that recently discovered drug-like compounds can be used in series to initially reduce water entry
and then enhance water exit over time Professor Yool says. Most current therapeutic approaches are limited in their ability to reduce injury-induced brain swelling

The new technologies and concepts serve as models for other karst regions. Under the IWRM Indonesia joint project funded by the Federal Ministry of Education
For the first time they succeeded in completely filling a karst cave with water. In 2010 they handed the cave power station over to the Indonesian authorities.
The plant can supply 80000 people with water. For the water to reach the households in a clean state via the distribution network a team headed by microbiologist Ursula Obst who directs the partial project for water processing and water quality assurance developed methods for the central semi
-centralized and local processing of water. The water from the cave is filtered first with sand
in order to prevent turbid substances from entering the distribution network. In the next step bacteria in the tap water are reduced.
For this purpose the KIT scientists established a pilot plant at the hospital of Wonosari There bacteria in the water are reduced among others by UV radiation
and the addition of chlorine or by filtration using ceramic membranes. However these methods require high-voltage current
There animals and plants can pollute the water. We therefore recommend to cover the pool
The scientists also installed a sand filter that retains dirt and turbid substances when tapping the water.
Prior to use the inhabitants filter the water again with the help of a clay pot that is provided with very small holes.
The water released via these holes is potable. The pots are produced by Indonesian potters using local materials according to specifications made by the scientists.
Users take a small water sample and mix it with an enzyme substrate a nutrient that activates certain enterobacteria
Only if these enterobacteria are contained in the water they convert the substrate and a clearly visible yellow color develops.

These tiny eyeless water creatures recognize predators by their scent and zooplankton in the Upper Midwest have added never the spiny water flea to their stink list.
which is why the spiny water flea aka Bythotrephes (pronounced BITH-oh-TREH-feez) is devouring its way through the Great lakes and into the surrounding inland waters.
His group sampled the waters in dozens of sites from New york to northwestern Minnesota; they found 83 sites that were infested.
Bythotrephes is no big deal in its native waters. The zooplankton communities in Scandanavia and Northern europe have adjusted to it Kerfoot said.
It came in ballast water no question Kerfoot said. Like many aquatic invasive species it was transplanted by ships loading ballast in one part of the world and dumping it in another in this case the Great lakes.
Since Bythotrephes needs cool conditions it has gained not a footing in more southerly waters. But it is having a field day in a band of inland lakes stretching from eastern Ontario to northern Minnesota and in the cooler Great lakes.
That means that minnows taken from Bythotrephes-infested waters and used for bait elsewhere can poop viable eggs into the new lake.
