Scientists from around the world are at Gustavus Adolphus College in St. Peter this week for the 37th Nobel Conference. The conference got underway today with presentations by Nobel laureates and other scholars, who are discussing the contributions science has made over the past century... and what's left to be discovered in the next. They're also celebrating the 100th anniversary of the Nobel Prize. Conference director Tim Robinson says there are five nobel laureates on hand to explain their work.
