Arab League observers arrived in Syria Monday, prompting a tentative calm between anti-government protestors and security forces. But many Syrians are skeptical that the monitors can permanently quell the unrest.

On an October night in 1859, 21 men staged a takeover of a national armory in tiny Harpers Ferry, Va. Though unsuccessful, the raid drew the nation's attention to its electrifying leader, a man named John Brown — and set the nation on the path to war.

Brown went on to become perhaps one of the most polarizing figures in American history. The devout Calvinist and abolitionist is remembered as a traitor and terrorist by some, and a hero by others.

This is TALK OF THE NATION. I'm Neal Conan in Washington. No nuclear power plants have been built in this country since the accident at Three Mile Island more than 30 years ago. The old reactors continue to provide 20 percent of our electrical power, but many of them will start to come offline in the next 10 years or so.

If you've ever lamented the time and effort it takes to brew or procure a cup of coffee, this might perk you up. "Breathable Energy. Anytime. Anyplace."

That's the campaign slogan for AeroShot, a plastic inhaler, roughly the size of a lipstick tube, filled with a powdery, calorie-free mix of caffeine, B vitamins, and citrus flavors. It's slated to hit stores in January, just in time for the New Year.

But some aren't so sure selling caffeine in pocket-sized tubes — and marketing it to young people — is a great idea.

Hospitals are often eager to embrace the latest medical technology, but the road to deploying tablet computers has been a little bumpy.

This month, consumer confidence jumped to its highest level since April, a sign that the U.S. economy is starting to mend. But the housing market isn't going along yet with this cheerier mood: Home prices were down 3.4 percent for the year as of October, according to a new report released Tuesday.

The death toll in Syria keeps mounting, as do the calls for the ouster of President Bashar Assad. But in dealing with Assad, should the international community threaten him with prosecution at the International Criminal Court or offer him a comfortable exile?
