A law signed into law last month in Missouri is making waves nationally, this week. A small part of the wide-ranging SB54, makes it illegal for teachers to be "friends" with students on any social networking site that allows private communication.

Reaction was swift in Alabama on Tuesday after the Justice Department filed a lawsuit to block a new immigration law set to take effect next month.

Alabama's new law — considered the toughest in the country — requires authorities to confirm the status of anyone they stop if there's reasonable doubt that person could be in the U.S. illegally. The law makes it a crime for undocumented immigrants to work, rent an apartment or get a driver's license.

Confessed Norwegian mass murderer Anders Behring Breivik's "manifesto" references many statistics and papers dealing with both science and global population studies. But what if you were a writer — and you learned that the man who killed 77 people had quoted some of your work?

With the Senate's passage of the debt-ceiling legislation and President Obama having signed it Tuesday afternoon, the nation no longer needs to worry about defaultmageddon, at least not until early 2013 when the U.S. Treasury once again runs out of the room to borrow again.

But even though there wasn't a default, the fight left plenty of wreckage laying about.

We all know that exercise is good for us, but sometimes it can seem too hard to even detach from the couch.

The budget deal struck by President Obama and congressional leaders is enough to merit a triple-A credit rating from Fitch Ratings, one of the three big ratings agencies.

Politico reports:

"Agreement was reached on an increase in the United States' debt ceiling and, commensurate with its 'AAA' rating, the risk of sovereign default remains extremely low," the agency said.

The battle over the debt ceiling may be over, but Congress remains deeply divided.

"Republicans are now taking a well-deserved victory lap while the Democrats are in a state of near total dejection," says journalist Robert Draper. "The Republicans got some cuts, they kept some revenue off the table but most of all, what they've done is dramatically shift the ethos in Washington."

The Japanese women's soccer team stunned the United States a few weeks ago. After a tense match in which Team America seemed to have the upper hand throughout, Japan leveled the game with a late equalizer and then went on to win a penalty shootout.

In the years after Fidel Castro's Cuban revolution, Havana's neighborhoods went through an extraordinary upheaval. As wealthy and middle-class families fled, poorer Cubans moved into their homes.

Now, communist authorities are preparing to legalize property sales for the first time in 50 years, and the city's old racial and class divisions are already creeping back.
