Water

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.

Despite being the closest planet to the Sun, Mercury is home to a surprising amount of ice. Now, researchers at Georgia Tech have put forward an explanation for how at least some of it got there – and it turns out, the heat plays an important role.

Aquatic hypoxia can be a serious problem, producing oxygen-depleted "dead zones" in lakes or seas. New research suggests that a process known as downwelling may help keep those zones from forming – although it wouldn't be a cheap solution.

Astronomers have analyzed the atmosphere of a large exoplanet and found that it could have liquid water – and so possibly life – on its surface. This new study adds weight to the idea that habitable exoplanets don’t have to be strictly Earth-sized.

It's vitally important to monitor the water quality of fish farms, as problems such as pollution can quickly prove disastrous. A small new floating cube was designed with this in mind, as it continuously tracks multiple factors.

We've already heard about so-called "fog harps" that use thin wires to collect airborne water droplets, providing drinking water. Well, an experimental new device also uses wires to capture water vapor, although it proceeds to generate electricity.

Desalination is an important technology that may help unlock more drinking water, and now two independent teams have developed new types of solar-powered desalination systems using very different mechanisms.

Clean water is all around us – it's floating around in the air most of the time. Of course, it’s not particularly drinkable in that form, but now researchers have found materials that can collect huge amounts of water from the air.

Adding chlorine is a common method of disinfecting drinking water, but just how safe is it? Johns Hopkins scientists have found evidence that reactions between chlorine and natural compounds in water may produce previously-unknown toxic byproducts.
