A new technique can extract oil from fouled beaches, and is also a more environmentally friendly way of exploiting tar sands, says a team of researchers at Penn State University.
One of the biggest problems with large-scale solar power is the vast amount of land area required. Deserts such as the Sahara have been suggested, but a team from Israel's Solaris Synergy and France's EDF Group have another idea - put them on the water.
NASA believes it's discovered its first Earth-sized exoplanets - and five of them are in the 'Goldilocks zone' where conditions are considered favorable for life.
A team at Vanderbilt University has found a way of using graphene to create windshields that don't need wipers.
University of Utah researchers have developed a new way to purify water: zap microbes with electricity until they do the job for you.
Brown University planetary geologists have identified a spot on Mars which they say could have been one of the most recent habitable microenvironments on the planet.
NASA has concluded that there may be enough water on the moon to sustain a manned lunar base.
A Stanford University team has developed a new water purifier based on nanomaterials that could cut costs for clean drinking water dramatically.
There's been liquid water on the Martian surface throughout the planet's history, measurements by NASA's Phoenix Mars Lander suggest.
Would you eat meat grown in vats? No? Well, how about if you were really hungry? What could be better than a nice juicy cheeseburger with fries?
And does it really matter whether the meat was raised, grown or cloned?
A research team led by Brown University has found evidence of liquid water on Mars much more recently than previously reported.
A Singapore-based company has launched a portable fuel cell that can power gadgets using only water.
There's a lot more water in the moon's interior than previously believed, say scientists at the Carnegie Institution’s Geophysical Laboratory.
Evidence that a vast ocean may have covered one-third of the surface of Mars some 3.5 billion years ago gives new support to the idea that the planet may once have harbored life.
Scientists have discovered evidence sitting right under their noses that indicates there may have been more water on Mars than previously thought.
For the first time, water and organic molecules have been detected on an asteroid. The discovery lends plausibility to the theory that both life on earth and water arrived through asteroid strikes.
An MIT team has managed what amounts to artificial photosynthesis, using a modified virus and sunlight to split water into hydrogen and oxygen atoms.
Instruments aboard India's Chandrayaan-1 spacecraft have detected millions of tons of water ice near the moon's north pole.
It's looking more and more likely that Saturn's moon Enceladus has a large body of sub-surface water, increasing hopes that it may harbour life.
