In a monastery on the Tibetan plateau, monks swathed in crimson robes chant under silk hangings, in a murky hall heavy with the smell of yak butter. Photos of the exiled Tibetan spiritual leader, the Dalai Lama — seen by China as a splittist — are openly displayed, as if in defiance. But Chinese security forces have tightened their grasp on this region, and monasteries appear to be emptying out, gripped by an atmosphere of fear and loss.

The financial battle for the Republican nomination is tightening. Candidates spent a lot of cash in January — what with contests in Iowa, New Hampshire, South Carolina and Florida. Also spending a lot of money, as it turns out, were the richly financed superPACS that support the candidates.

Reports filed at the Federal Election Commission on Monday night show just how important a superPAC can be.

Officials in Mexico are offering a reward of nearly $1 million for the capture of 30 inmates who broke out of a prison in the northern state of Nuevo Leon on Sunday.

The governor says the inmates staged a riot, during which 44 people died, to create a diversion for their escape.

It was a jail break that epitomized the Mexican drug war: Rival gang members brutally killed each other, corrupt public officials looked the other way, and dangerous criminals went free.

Rian Bogley says he heard this song by accident – and it really hit home for him.

Squeezebox Stories: the tale of one of the first global instruments.

Modern computer games and their fast-paced graphics require an incredible amount of computing horsepower. So much, in fact, that the kinds of chips commonly used for gaming are now being built into some of the world's fastest supercomputers.

If you're a serious gamer, if realistic, detailed graphics get your pulse racing, you should write Jen-Hsun Huang a thank-you note.

A big reason for the slow recovery has been that the nation's battered banks haven't been able or willing to lend. There are signs that's changing and that bank lending is helping to support stronger growth.

Paul Kasriel, chief economist at Northern Trust, a Chicago-based bank, say his reading of Federal Reserve data has convinced him that banks have finally taken the baton from the Fed and are now making credit more available.

"We've seen a sharp increase in business loans on the books of banks," he says.

The eurozone crisis has focused attention on debt-burdened Greece spiraling into decline. Meanwhile, Portugal is seen as the international creditors' poster-child for obediently slashing spending and welfare benefits.

Nevertheless, the Portuguese national debt continues to grow, and the country is mired in recession and soaring unemployment.

The Portuguese national character has long been identified with Fado music. Raquel Freire, an activist with the local Occupy movement, says the melancholy style helps explain decades of resignation.

Squeezebox Stories, hosted by Marco Werman of PRI’s The World, is a sound-rich, narrative-driven documentary exploring the social history, multicultural adaptation and musical variations of the accordion.

The accordion is about much more than the Polka; it’s one of the first global instruments. Played all over the world – everywhere from Italy to China to Zanzibar – the squeezebox is a great vehicle for telling immigration stories.
