Graphene oxide causes radioactive material to "clump" out of water

By - January 12, 2013 2 Pictures
Removing radioactive material from contaminated water, such as that in Japan’s Fukushima nuclear power plants, could be getting a little easier. Scientists from Houston’s Rice University and Lomonosov Moscow State University have discovered that when flakes of graphene oxide are added to such water, it causes the radionuclides to condense into clumps. Those clumps can then be separated and disposed of. Read More

America's "greenest street" provides a blueprint for sustainable urban development

By - January 7, 2013 7 Pictures
A streetscape that includes natural landscaping, bicycle lanes, wind powered lighting, storm water diversion for irrigation, drought-resistant native plants and innovative “smog-eating” concrete has earned Cermak road in Chicago the title of “greenest Street in America” according to the Chicago Department of Transport (CDOT). Opened in October 2012, the first phase two mile stretch is part of the Blue Island/Cermak Sustainable Streetscape project which was introduced in 2009 with the aim of reducing overall energy usage by 42 percent.

Researchers produce hydrogen from sunlight, water and rust

By - November 12, 2012 4 Pictures
As scientists endeavor to increase the efficiency of solar panels, the challenge of storing the resultant energy cheaply and in an environmentally responsible way must also be met. To this end, researchers at Switzerland’s École polytechnique fédérale de Lausann (EPFL) have developed an inexpensive device that transforms light energy into hydrogen, for storage and later use. The new prototype makes use of sunlight, water, and metal oxides, including iron oxide – or rust. Read More

Gravity probe shows groundwater reserves slipping away

By - September 25, 2012 7 Pictures
Recently, drought seems to be a fact of life. As the lead photograph poignantly illustrates, most of the U.S. has been struggling with serious levels of drought for the past several years. Worldwide, drought affected areas include Europe, India and Pakistan, Russia, much of Africa, South America – the list goes on. But when the rains start again, everyone expresses great relief, not realizing that long-term depletion of groundwater reserves is part of the price for surviving drought. It was with this in mind that GRACE (Gravity Recovery and Climate Experiment), a joint U.S. and German space project, was designed a decade ago. Read More

Washit cleans you and your clothes simultaneously

By - September 19, 2012 4 Pictures
Water is a precious resource and in places like Australia and the U.K., the onset of summer coincides with restrictions on water use – hosepipes for watering gardens are banned, and showers are recommended over baths. But even taking a shower uses a fair amount of water, which all ends up down the drain. The same goes for doing laundry. If only there was a way to combine the two into one unified unit. There is, or at least there could be in the future. Four university students in Turkey have collectively designed Washit, a concept shower and washing machine combo that's capable of cleaning you and your clothes simultaneously. Read More

Superhydrophobic coating allows water to boil without bubbles

By - September 14, 2012
You know that thing that water does when it boils? The thing with the bubbles? Turns out, it doesn't really need to do that at all, with scientists finding a way to make boiling water a completely bubble-free zone. Researchers from Northwestern University, King Abdullah University of Science and Technology in Saudi Arabia and Melbourne University in Australia teamed up to prevent water from bubbling when it boils by using tiny spheres coated with a hydrophobic material.

Solar-powered oven makes fresh water

By - September 9, 2012 8 Pictures
Sometimes the simplest ideas are the best. Concerned about the lack of fresh water in the developing world, designer Gabriele Diamanti wanted a solution to desalinate water that was available to households rather than relying on giant centralized plants. He also wanted it to be something inexpensive that could be made by local craftsman. The result is a ceramic solar still called the Eliodomestico that operates like an “upside-down coffee percolator”. Read More
