NPR's Richard Harris talks with host Scott Simon about the Fukushima Dai-ichi reactors, one year after multiple meltdowns there spread radioactive materials across a swath of northern Japan. Huge technical challenges remain and prospects for resettling the area are uncertain.
This time last year, Col. Moammar Gadhafi was losing control of Libya. Scott Simon talks with Abdel-Rahim el Keib, the Libyan interim prime minister who took over in the wake of the country's uprising.
Host Scott Simon reports on the other candidates for the Republican nomination for president: Rick Santorum, Newt Gingrich and Ron Paul. This week, they've been campaigning in the South and Midwest in the hunt for votes and nominating delegates.
As the candidates stump for votes, Republicans in Kansas and two U.S. territories will caucus today, and pick their choices to be the Republican nominee this fall. Many voters will show their support for a particular candidate. Long before they cast any votes, they might put up a poster or plant a yard sign for their candidate. These signs spring up like mushrooms every campaign season. Do they actually work?
