Water

Geological evidence shows that ancient Mars had flowing water. It’s long been thought that its climate was warm and wet, but a new study has found evidence that the planet was instead covered in ice sheets, and much of its water glacier run-off.

DiFold believes it has a more convenient water bottle. Its Origami Bottle holds 25 oz (750 ml) of water as effectively as any solid bottle but quickly folds down via integrated creases, packing small enough to throw in a pocket or purse.

Earth is a famously watery planet, but where exactly it all came from is a mystery. Now researchers have suggested a new origin story, by showing that water and petroleum can form inside clouds of organic matter, at high temperatures and pressure.

A team of researchers at Eindhoven University of Technology in the Netherlands have drawn inspiration from a tiny tentacled marine creature to produce a centimeter-scale robot that is powered by magnets and light.

A research team from the US Army and the University of Rochester is throwing a new water purification solution into the mix, showing off a “superwicking” aluminum panel that uses solar power to purify water with great efficiency.

Engineers at the University of Liverpool have developed a robot scientist that can autonomously perform experiments, analyze results and decide what to do next based on those results – and it’s already making new discoveries on its own

Evaporation is one of the most enduring methods of purifying water to make it drinkable. Now researchers in China have developed a novel device made of wood that can do just that, by employing bacteria to help build key nanostructures.

Making biofuel from algae is showing promise as a green energy source, but it does create large amounts of toxic wastewater. Now, researchers in Australia have found a way to clean up that wastewater, with a simple and scalable electrical process.

When it comes to keeping buildings energy efficient, windows certainly pose a challenge. It was with this quandary in mind that a British scientist has created a new type of window – one that's filled with water.

Whether they're travellers or people living in developing nations, many folks may find themselves near the ocean and in need of drinking water. That's where the QuenchSea is made to come in, as it's a portable, relatively cheap desalination device.

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.
