At newsstands across France on Wednesday, readers will delight to a humorous broadsheet published every four years on leap day.

At news shops in Paris and around France, readers look forward to their copy of La Bougie du Sapeur every Feb. 29. Published since 1980, the satirical journal is now in its ninth edition. Its title, which translates as "sapper's candle," is taken from an old French comic-book figure who was born on that fateful last day of February.

To the list of weird-sounding hybrid words of the digital age, like Googling and tweeting, we can now add "pinning." As in Pinterest. It's sort of an online scrapbook or bulletin board, and it's one of the fastest-growing websites in history.

Last month, more than 10 million unique visitors signed on to Pinterest. But some of them, like Billy Winburn, are still trying to get the hang of it. At an office in Alexandria, Va., Jennifer Folsom, who works a few desks away, is walking him through the process.

Something that only comes around once every four years and doesn't involve either politics or Olympic competition deserves its own mention:

Wednesday is Feb. 29.

Leap day, that is.

Our friend Linton Weeks has put together a handy list of 24 things you could do with the extra 24 hours. (And yes, we know that some of you have already started your day; but, hey, we're an East Coast-based blog.)

Americans who turn up in the emergency room to get dental care aren't lost, they're probably just running out of options.

According to a new report from the Pew Center on the States, more than 800,000 visits to the ER in 2009 were for toothaches and other avoidable dental ailments.

Virtually everyone expected Tuesday's big political news to come blowing out of Michigan, the big industrial state, where Mitt Romney and Rick Santorum were vying to win that state's GOP presidential primary.

But little Maine managed a national political bombshell of its own with the surprising news that Sen. Olympia Snowe, the 65-year old, three-term moderate Republican senator, won't seek re-election.

From a statement she issued, it appears Washington's partisan bickering just got kind of old for the senator.

Another Tuesday, another critical day for the 2012 Republican presidential contenders.

This time the locations are Michigan, where most polls close at 8 p.m. ET, and Arizona, where voting ends at 9 p.m. ET. The story political junkies are watching closest: Will former Massachusetts Gov. Mitt Romney, a Michigan native, hold off a strong challenge there from former Pennsylvania Sen. Rick Santorum?

Also on the ballots, of course: former House Speaker Newt Gingrich and Rep. Ron Paul, R-Texas.

When he returned from Afghanistan and saw his partner waiting to welcome him home, "four years of pent-up emotion and secret love" just seemed to naturally lead to "what felt like an eternity kiss," Marine Sgt. Brandon Morgan told NPR this afternoon.

If you take a cholesterol-lowering drug called a statin, there's some new safety information you should know about.

A statin might be why you're having trouble remembering things or have been feeling confused, or at least that's what quite a few people taking the drugs have been saying.
