The Supreme Court takes up the Affordable Care Act next week, and NPR will be exploring the questions surrounding health care in America beforehand. Many of the publicly debated issues in the act hinge on money. How much is spent on our health? Who spends it? How?

Some know how much we pay for our own medical care, but many aren't aware of how immense an industry health care is in the U.S. Our trips to the doctor employ a lot of people, and our schools play an important role in preparing those people to take care of us.

At the end of 2011, Apple had a very enviable problem. It's not too many companies that have more cash than they know what to do with, and for the electronics giant, that amounted to nearly $100 billion burning a hole in its pocket.

So it certainly pleased current and potential investors when Apple announced that, for the first time since the mid-1990s, the company will start paying a dividend.

There are some 7,000 spoken languages in the world, and linguists project that as many as half may disappear by the end of the century. That works out to one language going extinct about every two weeks. Now, digital technology is coming to the rescue of some of those ancient tongues.

Members of the Native American Siletz tribe in Oregon say their native language, also called "Siletz," "is as old as time itself." But today, you can count the number of fluent speakers on one hand. Siletz Tribal Council Vice Chairman Bud Lane is one of them.

The U.S. spent $2.6 trillion on health care in 2010 — more than the entire economy of France or Britain. But the amount spent and how it's used varies from state to state.

And no two states are more different than Texas and Massachusetts. At 25 percent, Texas has the highest rate of uninsured people in the nation. Massachusetts, where a 2006 law made coverage mandatory, has the lowest rate — fewer than 2 percent of people are uninsured.

More than 80,000 of Albert Einstein's papers, including his most famous formula — E=mc² — and letters to and from his former mistresses, are going online at Hebrew University of Jerusalem.

As NPR's Lourdes Garcia-Navarro says on All Things Considered, "what the trove uncovers is a picture of complex man who was concerned about the human condition" as well as the mysteries of science.

When Michael Weber gave up animal products in 2003, the packaged food industry didn't have much to sell him.

"That early vegan food was either really hippy-ish or really processed," Weber tells The Salt. "It wasn't that high quality."

Nowadays, a stroll through a grocery store might just lead you to a freezer or cooler jammed with dozens of flavors of veggie burgers, meatless buffalo wings, dairy-free cheese and ice cream, and maple bacon tempeh.

Children who are exposed to methamphetamine before birth can have behavior problems as young as age 3, a new study finds. But those problems are manageable, the researchers say, especially if the children and their parents get help early on.

"These kids are not cracked and broken," says Linda LaGasse, an associate professor of pediatrics and Brown University Medical School, and lead author of the study. "But they do have problems that are worthy of note."

Pope Benedict XVI is set to begin his tour to Mexico and Cuba on Friday. It will mark the pope's first visit to Spanish-speaking countries in Latin America.

With his visit, there have been two interesting developments:

-- First comes news that over the weekend, the Knights Templars Cartel in Mexico called for a temporary halt in the violence while the pope is in town.
