Study suggests smartphone screens could detect toxins in water

When we hear about smartphones being used to perform analytical tasks, there’s usually also a device that’s connected to the phone. According to a new study, however, a phone’s own touchscreen could soon be used to test drinking water and other liquids… Continue reading Study suggests smartphone screens could detect toxins in water

Mixed up membrane desalinates water with 99.99 percent efficiency

That ancient mariner was onto something when he said “water, water everywhere, nor any drop to drink” – the vast majority of water on Earth is undrinkable. Desalination could be a vital technology to meet the world’s drinking water needs, and now Korea… Continue reading Mixed up membrane desalinates water with 99.99 percent efficiency

Water study may wash out hopes for life on Venus

Hopes of finding life on Venus had already been dashed, but now a new study may have hammered the last nail into the coffin. New modeling of water activity on different solar system planets has found that Venus would be too dry for even the most extrem… Continue reading Water study may wash out hopes for life on Venus

“Reverse solar still” keeps its cool to wring drinking water from air

Engineers at ETH Zurich have designed a new device that can wring drinking water out of the air. The system works day and night, and doesn’t require any additional energy input, making it suited for use in remote or developing areas.Continue ReadingCat… Continue reading “Reverse solar still” keeps its cool to wring drinking water from air

Mangrove roots inspire efficient “synthetic tree” water purifier

Solar stills can be a very useful way to produce drinking water from dirty or salty water, but there’s plenty of room for improvements in efficiency. Now, engineers at Virginia Tech have developed a “synthetic tree” inspired by mangroves, that mimics t… Continue reading Mangrove roots inspire efficient “synthetic tree” water purifier

“Rogue planet” exomoons could potentially harbor water and life

Contrary to popular belief, not all planets orbit stars – some drift freely through the cosmos on their own. These cold, dark worlds don’t make great candidates for hosting life, but a new study suggests that their moons could be more habitable than th… Continue reading “Rogue planet” exomoons could potentially harbor water and life

Alien-like extendable secondary jaws allow moray eels to hunt on land

Most fish utilize a mouthful of water to swallow their prey. According to a new study, however, moray eels are unique in not doing so, allowing them to feed while out of the water … with some help from a second set of jaws in their throat.Continue Read… Continue reading Alien-like extendable secondary jaws allow moray eels to hunt on land

Simple catalyst could clean contaminated water on Earth and soil on Mars

As if Matt Damon’s character in The Martian didn’t have enough to worry about already, his Red Planet potatoes could be contaminated with perchlorates. But new research led by the University of California Riverside has identified a relatively simple ca… Continue reading Simple catalyst could clean contaminated water on Earth and soil on Mars
