Hartford Courant: Juha Javanainen, a physicist at the University of Connecticut’s Storrs campus, has been sentenced to community service and a year of probation following an explosion that took place last year in the backyard of his house. His son set off the explosion, having put together a homemade bomb from chemicals his father had bought for him. When the police and its bomb squad arrived at the house, they found that some of the unused chemicals were too volatile to remove. After evacuating the immediate neighborhood, the bomb squad detonated the chemicals.
