Water

The Martian landscape is dotted with evidence of ancient fluid flows. But were they caused by lava or mud? Experiments in chambers simulating Mars conditions have now shown that mud volcanoes could be responsible for some formations.

The newly launched GoSun Flow is a neat and portable water purification system that draws on solar power to clean water for washing and drinking, with the ability to squeeze into a compact carry case when it’s time to get on the move.

Researchers at Rice University have built a simple new solar-powered device that can create hydrogen for fuel by splitting water. It's similar to other “artificial leaf” designs but the team says it’s self-sufficient and relatively cheap to produce.

New research is shedding some light on the longstanding mystery of koala hydration. The study presents the first description of a previously unknown drinking behavior, showing the unique marsupials drinking by licking tree trunks during rain storms.

The first fossil of a Spinosaurus tail has been discovered, revealing large spines that indicate a paddle shape like a crocodile’s tail. That means this gigantic predator was a proficient swimmer, making it the first aquatic dinosaur.

NASA is planning to launch a tiny satellite aboard one of the most powerful rockets ever constructed, to hunt for ice hiding deep inside craters on the Moon’s surface that are bathed in perennial shadow.

While no one likes seeing plastic waste floating in our waterways, tiny "microplastic" particles are also a threat to the aquatic environment – and to human health. A study now suggests that nanocellulose could be used to remove them from the water.

By converting liquid salt water – or tainted water – into steam, it's possible to obtain pure, clean drinking water. Doing so could soon be cheaper and easier than ever, thanks to a newly developed material.

From extraordinary macro images to abstract aerial drone shots, water photography can take many forms, much like water itself. In photography social network Agora’s latest contest, H2O is celebrated in a spectacular collection of images.

To build a more complete picture of drought-stricken areas, NASA has developed its first global groundwater map, which it hopes will become useful way of monitoring water supplies as the world contends with ever-hotter temperatures.

The UK Department of Environment, Food & Rural Affairs has issued a warning: large areas of England will face significant risk of drought due to climate change, and water companies need to find billions of extra liters per day by 2050 to keep up.

Scientists at Japan's Nagoya University have come up with a new technology to treat contaminated water, using electrically charged nanocarbons to more effectively filter heavy metal ions from the mix.
