"Cargo was slowly moving along the bloated Mississippi River after a costly daylong standstill, while officials kept an eye on the lower Delta where thousands of acres of farmland could be swamped by water that is inching closer to the top of a levee."

"Emergency vents that American officials have said would prevent devastating hydrogen explosions at nuclear plants in the United States were put to the test in Japan — and failed to work, according to experts and officials with the company that operates the crippled Fukushima Daiichi plant."
