Water impurities key to an icicle's ripples
A group of physicists from Canada have been growing their own icicles in a lab in the hope of solving a mystery that has, up until now, continued to puzzle scientists.
Fast or superfast water transport?
(Phys.org) —There were high hopes of using carbon nanotubes, particularly for ultra-fast water transport to desalinate seawater. However, a simulation now reveals that these ultra-fast transport rates might ...
Plasma-treated nano filters help purify world water supply
(Phys.org) —Access to safe drinking water is a step closer to being a reality for those in developing countries, thanks to new research published today in Nature Communications.
Team finds how the world's saltiest pond gets its salt
Antarctica's Don Juan Pond might be the unlikeliest body of water on Earth. Situated in the frigid McMurdo Dry Valleys, only the pond's high salt content—by far the highest of any body of water on the planet—keeps it ...
Destroyed coastal habitats produce significant greenhouse gas
Destruction of coastal habitats may release as much as 1 billion tons of carbon emissions into the atmosphere each year, 10 times higher than previously reported, according to a new Duke led study.
Biofuel expert explains how future innovations could help realize algal biofuels' full potential
(Phys.org)—Scaling up the production of biofuels made from algae to meet at least 5 percent – about 10 billion gallons – of U.S. transportation fuel needs would place unsustainable demands on energy, ...
Microbial oasis discovered beneath the Atacama Desert
Two metres below the surface of the Atacama Desert there is an 'oasis' of microorganisms. Researchers from the Center of Astrobiology (Spain) and the Catholic University of the North in Chile have found it ...
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.
Experiment would test cloud geoengineering as way to slow warming
Even though it sounds like science fiction, researchers are taking a second look at a controversial idea that uses futuristic ships to shoot salt water high into the sky over the oceans, creating clouds that reflect sunlight ...
DNA prefers to dive head first into nanopores
(Phys.org)—In the 1960s, Nobel laureate Pierre-Gilles de Gennes postulated that someday researchers could test his theories of polymer networks by observing single molecules. Researchers at Brown observed ...
Large-scale production of biofuels made from algae poses sustainability concerns
Scaling up the production of biofuels made from algae to meet at least 5 percent—approximately 39 billion liters—of U.S. transportation fuel needs would place unsustainable demands on energy, water, and nutrients, says ...
Liquid saltwater is likely present on Mars, new analysis shows
(PhysOrg.com) -- Salty, liquid water has been detected on a leg of the Mars Phoenix Lander and therefore could be present at other locations on the planet, according to analysis by a group of mission scientists ...
Bioengineered marine algae expands environments where biofuels can be produced
(Phys.org)—Biologists at UC San Diego have demonstrated for the first time that marine algae can be just as capable as fresh water algae in producing biofuels.
New fresh water in Arctic could shift Gulf Stream
Scientists are monitoring a massive pool of fresh water in the Arctic Ocean that could spill into the Atlantic and potentially alter the key ocean currents that give Western Europe its moderate climate.
