Japanese choppers dump water on stricken reactor

Military helicopters deserted loads of seawater onto Japan's suffering nuclear multifaceted Thursday, rotating to combat-style plans while trying to cool excited uranium fuel that may be on the border of spew out more emission.

Place operators also said they were race to finish a new power line that could restore cooling systems and ease the disaster at the Fukushima Dai-ichi place on the country's northeast coast.

US approval of arms pact with Russia looking shaky

Senate endorsement of President Barack Obama's nuclear arms agreement with Russia, which once looked close up to a sure thing, is now in danger.

The management is scrambling to get enough Republican hold up in the Senate to ratify the New START treaty before the Democrats' preponderance shrinks by six in January.
