Anyone who's visited an aquarium or watched "Flipper" reruns knows how happy those dolphins look when they score a nice fat fish. But they might not be tasting that fish at all.

Our friend Liz Halloran reports that Mitt Romney "might just win in the South" today as Republicans go to the polls in Alabama and Mississippi to pick between the four remaining candidates for the GOP presidential nomination.

As she writes:

Hip replacements can do a lot of good, but they don't last forever.

To lower the failure rates of artificial hips, particularly in younger people, doctors have tried using metal-on-metal hip joints with larger heads.

"Strange things are happenin' to me" a bewitched Mitt Romney said recently to a crowd of Mississippi supporters. The former Massachusetts governor is right: Strange things do happen to folks, especially national political candidates, when they talk to us Southerners. They start drawling and twanging, trying to sound like us. Sometimes, they're mocking us; sometimes they're just trying to be friendly. We know the difference.

President Bashar Assad's forces have placed landmines "near the borders with Lebanon and Turkey" along routes used by refugees trying to flee the fighting inside Syria, the watchdog group Human Rights Watch reported today.

Saying it has collected "reports and confirmations from witnesses and Syrian deminers," the organization called such actions "unconscionable."
