President Obama came to South Korea to talk about global nuclear security with world leaders, but found himself trying to build a unified front against North Korea's planned rocket launch next month.

Obama and South Korean President Lee Myung-bak strenuously warned North Korea not to go ahead with the launch. In a speech Monday at the summit in Seoul, Obama used some of the toughest language he has ever used addressed to the leaders of North Korea.

Over the weekend, members of the New Black Panther Party showed just how tense the situation in the Trayvon Martin shooting has gotten: They offered a $10,000 bounty for the capture of George Zimmerman, who shot and killed the unarmed teenager.

The filmmaker James Cameron just completed the first solo dive to the deepest part of the ocean.

As we reported, the Challenger Deep, near Guam, is 6.83 miles underneath the water's surface and had only been visited once before in 1960.

Seventy years ago, 70 percent of U.S.-made cars came with a stick shift. The number is less than 9 percent today.

But at least one man is on a quest to reverse that slide.

Eddie Alterman loves automobiles. He's a gear head. He's the top editor at Car and Driver magazine. His whole career, he has watched the sales of cars with stick shifts decline. And when Ferrari failed to offer a manual option for the new 458 Italia, he said, enough's enough. Basta.

JACKI LYDEN, HOST:

I'm Jacki Lyden and this is TELL ME MORE from NPR News. Michele Martin is away this week. Coming up, spring hails all sorts of lovely flowers and in Washington it brings cherry blossoms on the trees that ring the city's tidal basin. We'll share the story behind the famed cherry blossoms in a few minutes. But first, the Supreme Court opens a three-day hearing today about the Obama administration's Affordable Care Act.

As the Supreme Court begins hearing arguments on the Affordable Care Act, Tell Me More continues the conversation about state reactions to the law. Guest host Jacki Lyden speaks with Florida Senate President Mike Haridopolos, about opposition to the Affordable Care Act in his state.

Jonathan Cohn is a senior editor at The New Republic.

When President Obama signed the Affordable Care Act two years ago, the law's proponents (including me) were confident of two things: That it would become more popular with time and that it would make our health care system more humane and efficient.

Last spring, when House Republicans passed Budget Committee chairman Paul Ryan's ambitious fiscal agenda, it would have been easy to make two basic guesses about the proposal's lasting impact: On the one hand, it seemed that the budget's focus on the immense scope of the fiscal calamity heading our way would put the deficit and debt at the center of our politics for the rest of Barack Obama's term. But on the other hand, it looked like the Medicare proposal in the budget would be highly controversial and politically risky.
