Under the guise of World Cup fever, scientists across the globe are seizing the opportunity to examine the aerodynamic properties of what will in all likelihood be the most talked-about object on a global scale over the coming weeks, the 2014 World Cup match ball. The ball, lovingly named Brazuca by the Brazilian people, is the product of a significant amount of research and money aimed at creating the ultimate centerpiece for one of the greatest sporting competitions on Earth.  Read More

Preliminary results of a study on how wind turbines interact with surrounding farm land ha...

Researchers from the Ames Laboratory and the University of Colorado have spent a few months wandering through corn fields on farms in the Midwest to gather information on how wind turbines interact with surrounding farm land. The data collected so far indicates that the turbines may offer more than the sustainable production of electricity, they may also benefit surrounding crops by helping them stay cooler and dryer, fight off attack from fungi and toxins and improve CO2 extraction.  Read More

Researchers have created a process to produce a light-absorbing layer on textured substrat...

The idea of boosting the performance of solar cells by coating them with a textured substrate is commonly used in silicon-based cells. The idea is to traps more light so that it bounces around inside the cell instead of reflecting back out, but for a number of reasons, attempts to use textured substrates in polymer solar cells have failed. Now researchers from Iowa State University and the Ames Laboratory have developed a process of producing a thin and uniform light-absorbing layer on textured substrates that improves the efficiency of polymer solar cells by 20 percent.  Read More
