The race for control of the Senate just got even more interesting with word from several news outlets that Sen. Ben Nelson (D-Neb.) won't be seeking re-election in 2012.

Brazil is now the world's sixth biggest economy overtaking the U.K., according to the Centre for Economics and Business Research. As the Financial Times puts it, it's another milestone that's part of a larger trend where emerging economies outpace developed ones. China, they report, overtook Japan earlier this year.

Congressional approval ratings are on the rocks, hovering in or near single digits for the first time since pollsters started measuring them. But just how bad is the current congressional stalemate?

Thomas Mann, senior fellow of governance studies at the Brookings Institution in Washington, is working on a book about Congress with a title that provides a succinct answer: It's Even Worse Than It Looks.

While pantomime performances of Snow White and Sleeping Beauty are traditional English holiday entertainment fare, there's a new hit in town. Londoners are flocking to Matilda the Musical, a souped-up version of Roald Dahl's well-known children's novel, playing in London's West End.
