The International Atomic Energy Agency released its much-anticipated report on Iran's nuclear program, but failed to conclude definitively that the Islamic republic is engaged in a full-scale weapons program.

Still, the U.N. nuclear watchdog's report raised some serious questions about what Iran is really doing in connection with nuclear weapons.

In Pakistan, several high-profile kidnappings reveal the cunning of the captors and confusion among police.

American aid expert Warren Weinstein was seized from his home in Lahore in mid-August. Two weeks later, publishing scion Shahbaz Taseer was snatched from his Mercedes at gunpoint, also in an upscale neighborhood of the Punjab capital.

The trail is leading investigators to Pakistan's militant-dominated tribal areas. North Waziristan, on the lawless Pakistan-Afghanistan border, is now believed to be a destination of choice for militant kidnappers.

This week, two U.S. airlines will be flying passengers on flights powered by biofuels for the first time. On Monday a Continental flight from Houston to Chicago used a biofuel blend made in part from algae, and Wednesday Alaska Airlines is set to fly passengers using a fuel made in part from cooking oil.

If all goes well, more airlines may start to use alternative jet fuels. But the shift is not without its challenges.

This was election day, and voters in Ohio rejected a referendum that would have limited the collective bargaining rights of state and local employee unions. Today's result is a blow to the state's Republican Governor, John Kasich, who had championed the measure.

OK, here's the idea: Greece leaves the EU and jumps to the SEC.

Bingo! With all the television and bowl money it would get, Greece would be solvent again, and the Southeastern Conference would get that big Athens TV market.

You see, everybody talks about how colleges are all switching conferences, but essentially, they all just want to jump to the SEC or whatever best emulates the SEC. It's the Solid South of college football. Once, the South used to control Congress. Now, y'all: the gridiron.

GOP presidential candidate Herman Cain gave a press conference to address allegations that he made unwanted sexual advances toward female employees and a woman seeking job advice in the 1990s. Cain emphasized that the accusations were false. NPR's Tamara Keith joins Robert Siegel to explain.

Former Arizona U.S. Attorney Dennis Burke came forward Tuesday to take responsibility for his role in leaking a memo and talking points that cast aspersions on a Bureau of Alcohol, Tobacco, Firearms and Explosives agent who had blown the whistle to Congress about a botched gun-trafficking operation.

Republican presidential candidate Herman Cain stood his ground, repeating that the accusations of sexual harassment made against him while he was the head of the National Restaurant Association are "false, anonymous, incorrect accusations."

In a press conference in Arizona, Cain repeated twice, "I have never acted inappropriately with anyone. Period." The former Godfather's Pizza CEO added that the scandal and the media feeding frenzy were not going to push him to quit the GOP presidential race.

"Ain't gonna happen," he said.
