Physics discovery named a top story\nIU professor Edward Stephenson's discovery of a rare fusion process explaining symmetry violation was named the No. 49 top science story of 2003 by Discovery Magazine. The discovery, which has been investigated since the 1950s, will help define differences between neutrons and protons and offer scientists insight into the origin of the universe, according to a press release.\nStephenson said in a statement the discovery explains an important phase in the evolution of the universe.\n"If this symmetry violation had happened to be in the other direction, hydrogen would not have survived after the Big Bang, and the universe would not have the hydrogen fuel that keeps stars shining, including our sun, making human life possible," he said in a statement. "Sometimes large consequences hang on delicate balances in nature." \nStephenson and his team made the discovery after two months of research at the IU Cyclotron Facility.
Study shows high toxins in farmed salmon\nIU researchers and five other research centers found higher toxin levels in farm-raised salmon than in wild salmon. The study, which could signify a health risk to people who eat the farm-raised fish, appears in this week's issue of Science.\nThe School of Public and Environmental Affairs distinguished Professor Ronald Hites led the study.\n"We think it's important for people who eat salmon to know that farmed salmon have higher levels of toxins from the open ocean," Hites said in a statement.\nThe study issued a recommendation of no more than two farmed salmon meals per month from studies in supermarkets in Los Angeles, Seattle, Chicago, New York, Washington D.C., and Vancouver. Wild salmon, meanwhile, tested safely with as many as eight meals a month.
