COLUMBUS, Ohio – A new study of the batteries commonly used in hybrid and electric-only cars has revealed an unexpected factor that could limit the performance of batteries currently on the road.
Researchers led by Ohio State University engineers examined used car batteries and discovered that over time lithium accumulates beyond the battery electrodes – in the “current collector,” a sheet of copper which facilitates electron transfer between the electrodes and the car’s electrical system.

UD joins research team teaching robots to respond in disaster emergencies
How do you teach a robot to get into vehicle and drive it? Three University of Delaware professors plan to figure it out by the end of next year.
Christopher Rasmussen, Ioannis Poulakakis and Herbert Tanner are part of a team competing in a new U.S. Defense Advanced Research Projects Agency (DARPA) Challenge. The team, with members from 10 schools, led by Drexel University, is one of several groups worldwide working to advance robotics technology for disaster relief. (more…)
American megachurches use stagecraft, sensory pageantry, charismatic leadership and an upbeat, unchallenging vision of Christianity to provide their congregants with a powerful emotional religious experience, according to research from the University of Washington.
“The megachurches movement is one of the leading indicators of how American Christians exercise their faith these days, so therefore they should be understood,” said James Wellman, associate professor of American religion at the University of Washington. “And our study shows they’re doing a pretty effective job for their members, based on self-reports, contrary to public opinion that tends to pass them off as a type of consumerist religion. In fact, their members speak eloquently of their spiritual growth.” (more…)
The 168 rectangular panels on the roof of the Katherine Moran Coleman Aquatic Center will generate enough power to keep the lights on and enough thermal energy to heat the million-gallon pool. The center, due to open April 13, will be Rhode Island’s first hybrid (heat and power) solar installation — also the largest in the nation and the first on a college campus.
