Physics Central: Physicist discusses "cracks" in the universe

An article on Physics Central's Buzz Blog reports a team of researchers have announced what they think are the first indirect observations of ancient cosmic string, and quotes UB student Robert Poltis, lead author of the paper that discusses the findings. "Their magnetic field sort of hitches a ride with the expansion of the universe," he said. The article appeared on Space.com, MinnPost.com and io9.com.
