Blissfully Unaware: Why Children Often Act Before They Think

If two men began a boisterous tug-of-war over the wine list at a posh restaurant, more than a few heads would turn. Yet two six-year-old kids quarreling over a pack of crayons at a diner would hardly seem unusual. It is normal for kindergartners to act out and for grown-ups to show restraint

Safety Concerns Often Amount to Status Quo at U.S. Nuclear Industry’s Aging Reactors

On December 1, 1969, Jersey Central Power & Light initiated fission in the fuel rods of the nation's first boiling-water nuclear reactor--one of 31 ultimately built in the U.S. The first "turnkey" plant, Oyster Creek nuclear generating station in New Jersey was sold for less than $100 million in 1964--a price well below what it would ultimately cost to build the reactor. The point was to prove that a nuclear power facility could be built as cheaply as a coal-fired power plant, and the key to that was a smaller safety system
