Dolphins have been stranding themselves along the shores of Cape Cod, Mass., since the Pilgrims' times, and this winter is no different.

Anti-government protests in Russia are taking many different forms, from mass rallies and marches to defiant street art and music.

Just recently, members of a feminist punk group were arrested in Moscow's Red Square after they performed a song ridiculing Prime Minister Vladimir Putin. The group, which calls itself Pussy Riot, says it's planning more stunts before March's presidential elections.

While Rick Santorum won Colorado along with two other states last night, he did not win the key Colorado county of Arapahoe.

CNN's political commentator Roland Martin has been suspended, because of tweets sent out during the Super Bowl that organizations like GLAAD called homophobic.

NPR's David Folkenflik reports that the network was also reacting to online criticism of Martin. David filed this report for our Newscast unit:

Most moms probably don't want their babies around pot growers, but San Francisco-based writer-photographer Lisa Hamilton is totally cool with it.

In fact, her baby, Ada, is a little over a year old and has probably already seen more of California than most Californians. And that, to Hamilton, is a problem.

For her, the basic issue is exemplified by something like this: We can see what a stranger in Japan is having for lunch on Instagram. But we can't so easily see where that lunch came from, or who harvested the ingredients.

It's been 30 years since Britain and Argentina went to war over the Falkland Islands. The British won, leaving the islands off the coast of Argentina in British hands.

Just hours before the symbolic rekindling of the Salt Lake Olympic cauldron, officials in Utah today sought to rekindle the 2002 Olympic spirit, announcing they're considering another Olympic bid.

The disclosure at the Utah Olympic speedskating oval in suburban Kearns, comes exactly 10 years after the 2002 Winter Games began.

"Ten years ago, Utah 'Lit the Fire Within,' and today that flame still burns bright," said Gov. Gary Herbert (R). In fact, as celebrations of the 2002 anniversary begin, some Utahns are wearing their official Olympic volunteer coats again.

If that case of diarrhea just doesn't get better, your heartburn drug could be the reason.

The Food and Drug Administration just warned doctors and consumers that popular medicines called proton pump inhibitors may raise the risk for chronic diarrhea caused by Clostridium difficile, a bacterium that you'd rather not have colonizing your intestines.

Spooning strained peas into a baby is the traditional way to start solid food. But babies might be better off feeding themselves.

That's the surprising result of a new study that compared the food preferences and weight of babies who fed themselves finger food with those who were spoon fed.

Both groups of children had equal exposure to snack foods. But the babies who fed themselves preferred carbohydrates like toast, pasta, or potatoes, while the spoon-fed children went for sweets when given a choice.

Mitt Romney can take solace Wednesday in the words of Mark Hanna, the 19th century Ohio industrialist and political boss who once famously said: "There are two things that are important in politics, money and I can't remember the second."
