Miracle moss removes arsenic from drinking water
While it's not the responsibility of plants to clean up the mess we humans seem to make of the planet, it is certainly kind of them to show us how it's done. The latest plant to offer an assist in environmental clean-up looks to be Warnstofia fluitans, otherwise known as floating hook Read More...
Water purification breakthrough can even clean water from the Dead Sea
Despite all our advances, access to clean water is still a major problem – not just for developing nations, but here in the US, where water shortages during natural disasters can cost lives. Scientists have created a cost-effective technology that addresses this problem using hydrogels. Using Read More...
How the citizens of Cape Town came together to avoid a major water crisis
During the California drought, which finally ended in late 2016, residents were still using on average 109 gallons of water per person per day. That’s rather shameful, especially when you compare it to the citizens of Cape Town, South Africa, where water levels are currently extremely low. There, Read More...
Fog harps could wrest water from the clouds
Inspired by coastal redwoods, scientists have created a new kind of fog harvesting design that appears to increase the capacity of clean water collection by Read More...
Checking if water is contaminated could soon be as simple as snapping a photo
Dutch researchers are developing a simple smartphone attachment that makes it ridiculously easy to measure the quality of water. All you have to do is point the tool at the water you want to measure.

The technology worked, but it wasn’t Read More...
A simple carbon-based filter can turn filthy saltwater into drinking water
Researchers in Australia have created a new type of water filter that can purify and desalinate water in a single step. Using a material made from a thin layer of pure carbon, the researchers were able to create a filter that only allows pure water molecules to pass through while rejecting all the Read More...
Researchers discover efficient way to filter salt and metal ions from water
With two billion people worldwide lacking access to clean and safe drinking water, joint research by Monash University, CSIRO and the University of Texas at Austin published in Sciences Advances may offer a breakthrough new Read More...
