In Harlem, a legendary congressman — one of the most influential black politicians in modern history — faced a difficult re-election as allies backed his younger opponent in demanding a changing of the guard.

That was in 1970, when challenger Charles Rangel defeated Rep. Adam Clayton Powell Jr., a mythic figure undone by scandal and frustrated constituents.

Now, 42 years later, Rangel is the iconic lawmaker contending with perhaps his toughest re-election against challengers from within his own party who say his time has passed.

The details sound like something out of a bad science-fiction movie.

A freezer storing human brains for research went on the fritz, and nobody at the Harvard Brain Tissue Resource Center knew for days. Two separate alarms that should have alerted staff to the problem failed to sound late last month.

A day after getting approval for a financial rescue he vowed Spain would never need, Prime Minister Mariano Rajoy said it was his idea all along.

"No one pressured me into this. I pushed for it myself, because I wanted a line of credit," Rajoy said. He refused to call it a "bailout." He called it a "victory" instead.

Most Spaniards don't buy that. In a poll published Sunday, 78 percent of respondents said they have "little or no" faith in Rajoy and his ruling conservatives. That's just six months after they won elections in a landslide.

It's easy to romanticize the Sahara — a vast expanse of sand organized around the northern reaches of the Niger River. Part of that romance is captured in the music of singer and guitarist Sidi Touré, who composes songs in the folkloric tradition of the Songhaï people.

His new album of desert chamber music, Koïma, harkens back to the glory days of the Songhaï Empire, which ruled much of the region from the city of Gao in the 15th and 16th centuries.
