"The official announcement that two reactors at an earthquake-damaged nuclear plant could be suffering meltdowns underscores the Japanese nuclear industry’s troubled history, and years of grass-roots objections from a people uniquely sensitive to the ravages of nuclear destruction."

"A second explosion rocked a troubled nuclear power plant Monday, blowing the roof off a containment building but not harming the reactor, Japanese nuclear officials announced on public television. The explosion underscores the difficulties Japanese authorities are having in bringing several stricken reactors under control three days after a massive earthquake and a tsunami hit Japan’s northeast coast and shut down the electricity that runs the crucial cooling systems for reactors.

"A new study about the way oil from the BP Deepwater Horizon accident evaporated into the air confirms that cleanup workers were exposed to high levels of airborne pollution, and that the fumes also may have made their way onshore in Louisiana."

An 8.9 magnitude earthquake struck Japan, shutting down major systems, killing at least 40, and causing a tsunami. Nuclear plants were shut down on an emergency basis after the cooling system at one plant failed. Tsunami warnings were issued through much of the Pacific, including Hawaii and parts of the U.S. West Coast and South America. Potential impact of tsunami on Hawaii within minutes of 8 am EST as hotels evacuate vertically.

"The Interior Department will study the potential impacts of a 'very large oil spill' in the Arctic Ocean as part of a court-ordered supplemental review of oil and gas leasing off Alaska's northwest coast, the agency said."

As a kids' plaything, it's called oobleck -- a cornstarch suspension that flows at slow speeds but freezes into a solid when you try to move it fast. Washington University scientist Jonathan Katz has just published an article saying it might have succeeded in a "top kill" of the Deepwater Horizon Gulf well where ordinary drilling mud failed.

"Facing a deadline that could mean the difference between doing business as usual or cutting pressure on hundreds of miles of natural-gas pipeline, Pacific Gas and Electric Co. has recruited employees to the Cow Palace grounds for a round-the-clock search through tens of thousands of boxes of paperwork."

An author tells the story of the Hawks Nest, WV, hydroelectric tunnel, whose drilling Union Carbide began in 1927. It was run as a mining operation, but not regulated by any government agency. Of the 5,000 men who worked on the tunnel over 18 months, at least 764 men, mostly African-American migrant workers, died of the industrial disease silicosis, well known even then. Managers wore protective masks during inspection visits, but did not provide any to workers. The company hired doctors to tell the men it was their fault, and buried them in unmarked mass graves. West Virginia kept the story out of the state's history curriculum until last year.

"More than two decades after the Exxon Valdez supertanker struck a reef and unleashed the nation's biggest tanker spill, a lingering legal dispute about the disaster heads back to court on Friday."
