All Things Considered

A majority of U.S. Supreme Court justices signaled Wednesday that they will uphold at least part of Arizona's controversial immigration law. Four provisions of the law were blocked by a federal appeals court last year, and while even some of the court's conservatives expressed skepticism about some of those provisions, a majority seemed willing to unblock the so-called "show me your papers" provisions.

The U.S. Postal Service is so much a part of this country, it's in the Constitution. And yet with so much written communication now delivered via email, text messages and the Internet, the Postal Service is steadily losing business and operating in the red.

Most people wouldn't think of Washington, D.C., as one of R&B's great cities. Despite the fact that soul music greats Marvin Gaye and Roberta Flack grew up in D.C. neighborhoods, the city never had the equivalent of Detroit's Berry Gordy and Motown, or Memphis' Willie Mitchell and Hi Records. But in the early 1970s, D.C. did have producer Robert Williams and his Red, Black and Green Productions. A new compilation album called Eccentric Soul: A Red Black Green Production revisits Williams' influence on the sound of R&B in D.C.

The idea of exploiting the natural resources on asteroids has been around for more than a century. But a new company called Planetary Resources has the financial backing of some big names in high tech, and hopes to launch specially-designed prospecting spacecraft within two years.

Former Massachusetts Gov. Mitt Romney is expected to win all five of the Republican presidential primaries being held Tuesday. The GOP front-runner hasn't had to worry about real competition since Rick Santorum dropped out of the race earlier this month.

But former House Speaker Newt Gingrich is still running for president, even though he's short on money and lagging far back in the polls.

It would be easy to confuse Dr. Mitch Katz with any other doctor at the Roybal Comprehensive Health Center in East Los Angeles. His desk in a closet-sized, windowless office is littered with patient records, X-rays and cans of Diet Coke.

His everyman demeanor belies his stature. As director of the county's Department of Health Services, Katz, 52, oversees Los Angeles' public hospitals and clinics, the health care of last resort for millions of low-income Angelenos. He oversees 22,000 employees and a $3.7 billion-dollar budget.

Why did Missouri teen Maura Pozek make her prom dress out of cardboard and paper bags?

Because after fashioning the previous two years' outfits out of Doritos bags and soda can tabs, "I had to top myself somehow."

"Follow the money." That's the mantra of modern political coverage, especially in the wake of the Supreme Court's Citizens United decision, which opened the floodgates of campaign cash.

Checking a candidate's contributors has become critical for understanding the candidate's politics. It's also easier than ever before with regular deadlines and electronic records — unless the legislator you are tracking is a member of the U.S. Senate.

For more than a decade now, the Senate has kept itself exempt from rules other federal candidates must follow.
