Synthetic biofilter removes estrogens from drinking water

Conventional methods of filtering waste water in sewage treatment plants are unable to completely remove medicine residues such as the estrogens in birth control pills. Students from the Bielefeld University's Center for Biotechnology have now developed a biological filter in which specific enzymes (so-called laccases) break down these medicine residues.

Carbon dioxide - our salvation from a future ice age?

Mankind's emissions of fossil carbon and the resulting increase in temperature could prove to be our salvation from the next ice age. According to a new research article by researchers from the University of Gothenburg, the current increase in the extent of peatland is having the opposite effect, cooling down the climate.

High-tech tools tackle wind farm performance

Researchers at the U.S. Department of Energy's (DOE) National Renewable Energy Laboratory (NREL) are learning how to better understand these issues and are working toward effective solutions for the wind industry. Their goal is to maximize turbine performance and minimize structural loads, which will ultimately result in lower-cost wind energy. Toward that goal, NREL researchers are leveraging the lab's supercomputing resources and have developed high-tech modeling and simulation capabilities.
