Desert Farming Forms Bacterial Communities That Promote Drought Resistance

November 5th, 2012 | by GBE FACTS

When there is little water available for plants to grow, their roots form alliances with soil microbes that can promote plant growth even under water-limiting conditions, according to research published Oct. 31 by Daniele Daffonchio and colleagues from the University of Milan, Italy in the open access journal PLOS


Next-Generation Antireflection Coatings Could Improve Solar Photovoltaic Cell Efficiency

October 29th, 2012 | by pressroom

Materials boasting a "tunable" refractive index have been developed within the past few years, and they show tremendous potential for photovoltaic applications. Professor E. Fred Schubert, of Rensselaer Polytechnic Institute's Department of Electrical, Computer, and Systems Engineering, is investigating ways to exploit this newly gained controllability and will present his findings at the upcoming AVS 59th International Symposium and Exhibition, held Oct. 28 - Nov. 2, in Tampa, Fla


Want to Encourage Eco-Friendly Behavior? Give Consumers a Nudge (Don’t Tell Them What to Do)

September 12th, 2012 | by GBE FACTS

Influencing sustainable behavior is an ongoing challenge in today's world. Hotels often ask consumers to "do their part" for the environment by reusing towels, but this approach has limited success. Appeals to adhere to social norms (i.e., informing guests that the majority of guests in a hotel reuse their towels) have been shown to be more effective, yet leave an estimated 50% of hotel patrons unresponsive


Biofuel Waste Product Recycled for Electricity

September 5th, 2012 | by pressroom

A byproduct of biofuel manufacture can power microbial fuel cells to generate electricity cheaply and efficiently, according to scientists presenting their work at the Society for General Microbiology's Autumn Conference. The work could help develop self-powered devices that would depollute waste water and be used to survey weather in extreme environments
