As we've been saying, it's finally time for voters to cast some ballots that actually mean something for the 2012 presidential race.

Young voters came out in huge numbers to elect President Obama in 2008. This year, with no primary contest, Democrats are using their caucuses to test how much support they have in Iowa. But many young liberals have grown disenchanted with the president, and some have thrown their support behind Republican Ron Paul.

On Monday, 10 Obama for America volunteers made calls to registered Democrats from a Panera Bread turned phone bank just outside of Des Moines. The volunteers reminded Democrats when and where to show up to caucus.

Most patients who undergo bariatric surgery lose weight and experience other health benefits. They have less heart disease, diabetes and cancer than their obese counterparts who don't have the surgery.

Now, researchers from the University of Gothenburg in Sweden find bariatric surgery also reduces deaths from cardiovascular causes, such as heart attacks and strokes.

There was a bit of progress made in the Israeli/Palestinian conflict, today: Peace negotiators from both sides met for the first time in more than a year. While it did not seem that the two sides came to any agreement, they said they will continue to talk.

If you, like me, order a tall coffee when you go to Starbucks, you'll be paying 10 cents more. The Seattle coffee chain is raising prices in the Northeast and across the Sunbelt with the exception of California and Florida.

Cities like Boston, New York, Atlanta and Dallas will also see an increase of about 1 percent on other drinks. Starbucks said its next bigger size, grande, will cost the same.

There are an estimated 37 million Americans who have some college credit but no degree — and Western Governors University is trying to change that. The nonprofit online school is challenging many traditional concepts about higher education with a new approach aimed to help adult students finish college.

And after 15 years in existence, the school is catching on.
