A researcher at Switzerland's University of Zurich has combined 25 years worth of satellite imagery to show the complex behavior of glaciers in a single second. The effort made use of data collected by NASA's Landsat satellites, focusing on the Karakoram mountain range in Asia.
Industrial designer Carter Zufelt has created a new process for recycling discarded plastics. Unlike most current methods, his is able to transform garbage into uniquely-crafted art. Not only can the process be replicated in the comfort of one's own home, but through his sustainable project Müll, Zufelt is choosing to make it available to all those interested.
Last year around 2.3 million barrels of oil were pulled each day from tar sands in Alberta, Canada, the third largest oil reserve in the world. This mining process is hugely water-intensive, and though much of it is recycled, it still results in massive pools of polluted wastewater which are difficult to treat and pose a threat to the environment. Canadian researchers have developed a new approach to removing the contaminants using sunlight and nanoparticles, an approach they say will prove much more effective and cheaper than existing methods.
As access to clean water continues to be an issue throughout the developing world, there's an increased demand for easier ways to turn contaminated and salty water into something you can drink. Researchers at MIT may have found a solution using a method they are calling shock electrodialysis. It uses electric shock waves to separate contaminated or salty water into two separate streams, with a natural barrier between each one.
In a deal between the Scottish government and Norwegian oil company Statoil, five wind turbines with a capacity of six megawatts each will be set on floating structures some 15 miles (25 km) off the northeast coast of Scotland near Peterhead. The Hywind pilot park, as it's named, is claimed to be the first floating wind farm in the world, and will generate enough power for 20,000 homes with operations expected to start in late 2017.
In recent years, satellite photos of Greenland's ice sheet have shown what appears to be a darkening of the ice's surface. A number of scientists have suggested that this could be due to settled soot particles from fossil fuel production and/or forest fires, and that their presence could result in accelerated melting of the ice. Now, however, researchers from Dartmouth College believe that the ice may still still be relatively clean, and that its darkness in the photos could just be due to faulty sensors on the satellites.
Researchers at the Technological Institute of the Lagoon (ITL), Mexico, have created a nanoparticle-rich, superconducting ink that they have used to coat pipes of solar water heaters to increase their efficiency by up to 70 percent. The new coating was recently proven on the solar heating of a Mexican city sports complex swimming pool, where 2 million cubic meters (70.6 million cubic feet) of water were heated from 26 °C to 37 °C (79 °F to 98°F).
Chemical pesticides are generally a bad thing for the environment and pollinators like bees that our agriculture relies on. Now a company out of Vancouver, Canada, called Bee Vectoring Technology (BVT) has brought the two together in a system that uses bees to deliver tiny amounts of natural pesticides and beneficial fungi while pollinating crops.
Scientists have discovered that a bacterium called Thiomicrospira crunogena can produce carbonic anhydrase, an enzyme that can convert carbon dioxide into bicarbonate. In a new study, scientists from the University of Florida highlight how the bacterium, found in deep-sea regions, could play a role in the race to find solutions to sequester industrial CO2 from the atmosphere.
An Israeli-Palestinian NGO is using solar and wind energy to transform the lives of a marginalized community of Palestinian famers and shepherds. Founded in 2009, Comet-ME has helped develop small off-grid systems that now provide an average of 2.5 kW h per family per day across 20 communities.
