The question of whether the presidential election results in Iran were fair may never be answered. The BBC's Jonathan Marcus joins us with his analysis of the unfolding situation. And to explain how to analyze an election's honesty, we turn to someone who has monitored elections all over the world, including the Middle East. Eric Bjornlund, president of Democracy International, a consulting firm that helps governments create free and fair elections joins The Takeaway. He's also the author of the book, Beyond Free and Fair: Monitoring Elections and Building Democracy (Woodrow Wilson Center Press) .

The Supreme Court ruled 5-4 that post-conviction DNA testing is not a Constitutional right for convicted criminals. So far, post-conviction DNA testing has exonerated at least 232 people nationwide. The ruling came on an appeals case by William Osborne, who was convicted for the 1993 rape, kidnapping and assault of a prostitute in Alaska. The Innocence Project, a group of attorneys who help prisoners obtain DNA testing, has been defending him for seven years. Nina Morrison is a staff attorney at the Innocence Project has been working on his case and joins us today.

Tens of thousands of people gathered at Tehran University to hear Supreme Leader Ayatollah Ali Khamenei speak. Despite Khamenei's assurances that the election was fair, and his urging to stay off the streets, protests continued.

As golf's U.S. Open starts up, the biggest story is the weather. Days of rain in New York have made for a group of soggy players and an extremely wet course. Tiger Woods tries to defend his title, while fan favorite Phil Mickleson tries to focus on the course while his wife battles breast cancer. For analysis and predictions we turn to Bob Harig, golf writer for ESPN.com.

The National Assessment of Educational Progress asked eighth graders across the country in 2008 a series of questions on music and visual art. The results of that test, revealed on Monday, may be disappointing to some.

Some of the questions asked were:

•Identify form of musical examples as theme and variations.

•Identify pitch contour of melody in a recording

•Identify an example of 20th-century western art

•Identify compositional emphasis in a Bearden collage

•Identify a compositional feature of a medieval artwork

Could you answer these questions? The previous test in 1997 revealed low scores, and the 2008 results are even lower. Is cultural literacy being lost? Joining us on the show is Richard Kessler, executive director of the Center for Arts Education. Also joining the conversation is Emily Downs, an art teacher for elementary school kids in New Jersey.

With all the contentious debate over health care right now, Republicans and Democrats agree on one thing: they want to encourage disease prevention. This stems from the idea that by investing some money up front, you can keep medical costs lower, saving money (and improving quality of life) down the road. Senator Tom Harkin (D-Iowa) authored a portion of a health bill focused on prevention and wellness and he sat down with The Takeaway's Washington Correspondent Todd Zwillich to discuss his take on health care reform.

Then we turn to Louise Russell. Ms. Russell is a research professor at the Institute for Health, Health Care Policy and Aging Research at Rutgers University in New Brunswick, New Jersey. Her research challenges the idea that preventive medicine lowers the cost of medical care. The money we are investing in prevention may be doing little to improve the nation’s overall health.

Much has been made of the microblog Twitter and its influence on the ongoing protests in Iran. In fact, over the weekend the U.S. State Department asked Twitter to postpone scheduled site maintenance to avoid disturbing the tweets from Iranian protesters. But how much of a role has Twitter actually played in organizing protests and connecting supporters? Nicholas Thompson is the senior editor at Wired and he joins us with his thoughts on whether the revolution will be tweeted.

As protests continue, our partners at the BBC continue to receive interesting emails direct from Iran. Joining us is the BBC's Siavash Ardalan, a presenter with an international talk show program at the BBC's Persian TV in London. The BBC's Persian TV has received thousands of emails already this morning.

For almost a week now, the protests in Iran have topped the news headlines. Thousands of protesters have filled the streets while others fill university halls to hear the Ayatollah.

You might think that the image of the bumbling father is as old as parenthood itself, but just in time for Father’s Day, The Takeaway talks to one father who says differently. Jeremy Adam Smith is the author of The Daddy Shift: How Stay-at-Home Dads, Breadwinning Moms, and Shared Parenting AreTransforming the American Family. Jeremy also writes the blog Daddy Dialectic. Also joining the conversation is one very important Dad, Don Lanpher, father of our very own Katherine.

150 years after the Civil War, the U.S. Senate passed a resolution to apologize for the nation's ignominious history of slavery. The resolution passed unanimously. But who does the resolution really help: African Americans—or senators? For his thoughts on this late apology, we turn to a friend of The Takeaway, David Wall Rice, an assistant professor of psychology at Morehouse College.
