"Twin suicide car bomb blasts ripped through an upscale Damascus district Friday, targeting security and intelligence buildings and killing at least 40 people" according to authorities, The Associated Press writes.

NPR's Deborah Amos says it's the "first such attack since the beginning of a 10-month revolt" against President Bashar Assad's regime.

Now there's the question of who is responsible.

It's said to be made of a "metal alloy known to man," according to Agence France Presse. (We enjoyed that Spock-like line.)

But there's much that isn't known about what's being called a "space ball" that came down in Namibia last month: Such as where or what it came from.

Officials from NASA and the European Space Agency have been contacted.

The political maneuvering continues in Washington as lawmakers debate how to extend about-to-expire payroll tax cuts and jobless benefits for the long-term unemployed.

Seven years ago, an estimated 230,000 people died after an earthquake triggered a massive tsunami that devastated South Asian coasts from Indonesia to Thailand, Sri Lanka and India.
