A couple of really rich guys have decided to give even more money to health causes they care about deeply.

New York Mayor, media magnate and public health zealot Michael Bloomberg said he will give $220 million to fight smoking in the developing world. Bloomberg's charitable foundation has targeted tobacco use.

And the latest chunk of money, which is part of a four-year commitment, will bring Bloomberg Philanthropies' support of anti-smoking efforts around the globe to more than $600 million.

A new paper released by Princeton's Woodrow Wilson School of Public and International Affairs suggests that U.S. policies regarding immigration unintentionally encourage immigrants to stay in the country, whether or not they entered legally. Despite swelling budgets for border control and immigration security, the number of temporary workers entering the country hit 517,000 in 2010, the highest number in history... 

Things were not quiet again in Clintonville, Wis., early today.

As we reported Wednesday, folks there have been hearing booms and feeling vibrations this week and no one has yet been able to explain what's causing them. One of the latest theories is that unusually warm temperatures are causing underground ice to crack. A few homeowners think they've suffered some damages (cracked floors, for example).

Next week, the Supreme Court will hear challenges to the Affordable Care Act. In the first of a series of conversations about the case, host Michel Martin sits down with Michael Cannon of the Cato Institute. Cannon opposes the law and his group has filed four briefs with the high court, arguing that key parts of the measure are unconstitutional.

Suzanne Collins' novel The Hunger Games and its two sequels are smashingly well written and morally problematic. They're set in the future, in which a country — presumably the former United States — is divided into 12 fenced-off districts many miles apart.

Each year, to remind people of its limitless power, a totalitarian government holds a lottery, selecting two children per district to participate in a killing ritual — the Hunger Games of the title — that will be televised to the masses, complete with opening ceremonies and beauty-pageant-style interviews.

Bedouin tribesmen on Egypt's Sinai Peninsula rely on tourists for their livelihood — taking them on safaris, selling them trinkets, renting them huts at no-frills resorts on the Red Sea.

But these days, some Bedouins are using tourists for something completely different: as hostages in their political battle with the Egyptian government. In one recent incident, the tribesmen kidnapped two Brazilian tourists to secure the release of imprisoned relatives. The kidnappers released the women unharmed a few hours later.

At 54, Don Verrilli Jr. stands tall and calm in the Supreme Court chamber, his salt and pepper mustache the only thing about him that bristles. His deep, baritone voice suggests to the justices that he is the essence of reasonableness. There are no histrionics. Indeed, if he gets backed into a corner, his voice just gets deeper. Only the occasional, needless throat-clearing betrays any nerves at all.

A New Hampshire man who claimed last year that for a fee of $135 he would arrange to have your dog walked if the Rapture did indeed begin last May 21 and you got taken up to heaven, is now saying that his business venture was a hoax.

Allegations of phone hacking and bribery brought down Rupert Murdoch's tabloid News of the World. Criminal and parliamentary investigations are now under way in the U.K., and dozens of journalists and top executives from Murdoch's paper have been arrested.

Scotland Yard has been investigating the scandal, but several police officials from that iconic institution have also been implicated; they're accused of accepting bribes from reporters at Murdoch's papers.
