Extreme forms of life -- from organisms living in the scalding water of hot springs to the possibility of life away from Earth -- will be the focus of a symposium at the University of Colorado at Boulder. The symposium, "The Extremes of Life," will be held Thursday, Aug. 31, at 7 p.m. in the University Memorial Center's Glenn Miller Ballroom and will feature a panel discussion. The event is free and open to the public and is geared toward a broad audience.
