The Mexican muralist Diego Rivera painted in New York City, San Francisco, Detroit, Europe and the Soviet Union. But some of Rivera's most famous murals and most unusual projects are found in Mexico City.
In Mexico City, Rivera did far more than just paint. He collected pre-Hispanic pottery and indigenous folk art. And he experimented with sculpture and architecture.
And between 1950 and 1952, Rivera built a giant tiled fountain to the Aztec rain god Tlaloc as part of an overhaul of Mexico City's municipal water system.
In February 1945, Hershel Williams was sent to Iwo Jima with a flamethrower unit. All but 17 of the 279 members of his company had been killed or wounded a week and a half later.

Col. Jack Jacobs was awarded a Medal of Honor for his service in Vietnam, where he once <a href="http://www.npr.org/books/titles/144032956/medal-of-honor-potraits-of-valor-beyond-the-call-of-duty#excerpt">brought 13 fellow soldiers to safety</a> after enemy forces opened fire.
Today marks the 150th anniversary of the Medal of Honor. It is the highest military decoration in the United States, reflecting great service and sacrifice. Of the more than 3,400 recipients, fewer than 85 are still living.
Among them is Hershel Williams, who served as a Marine corporal in World War II. He says that on the day he received the honor — Oct. 5, 1945 — he had no concept of it.
Let Iran off the hook or undermine the global economy? Slap sanctions on an Iranian energy company or provide Europe with an alternative to Russian gas? Washington policymaking is especially difficult when the aims conflict, and few cases illustrate that principle more clearly than the challenge of finding a way to punish Iran without hurting someone else.

Former NHL hockey player Sheldon Kennedy testified before the Senate subcommittee on children and families during a hearing on child abuse. As a young teen, he said, he was sexually abused for years by a respected hockey coach, but the adults around him who suspected never said a thing.
The revelations about alleged child sex abuse by a former Penn State football coach have caused policymakers to propose new measures to broaden who is required to report suspected abuse.
Each state already has laws that require some combination of doctors, teachers, day care providers and others who work with children to report suspected abuse. If they don't, they could face fines, the loss of a license, and, in some states, possibly jail time.
In California, prison inmates who have committed serious crimes and have been diagnosed with a major mental illness can be forced to serve their parole in a state hospital. At Atascadero State Hospital, shown above in this 1999 photo, there are more than 600 such patients. "As a group," says the hospital's director, "the mentally disordered offenders are the most aggressive."
Mental health and law enforcement officials in California are trying to find ways to hold violent psychiatric patients accountable without punishing people for being sick. It's a response to escalating violence in the state's mental hospitals, where thousands of assaults occur annually. Only a tiny fraction of them, however, result in criminal charges.
This time last year, Phil Jackson, then the coach of the Los Angeles Lakers, complained that the NBA scheduled games on Christmas Day. It seemed, he said, that "Christian holidays don't mean anything" any longer.
A few players echoed Jackson's sentiments, but the complaint died aborning. This Christmas, Sunday, the league has scheduled ... (to the tune of "The 12 Days Of Christmas"):
Apple's iPhones may seem more cool, but the Google-backed Android phones are much more popular in the United States. In 2011, Android's U.S. market share was 53 percent, compared to 29 percent for the iPhone, according to the research group NPD.
Sleepy police were likelier to fall asleep while driving, a new survey of nearly 5,000 officers in the U.S. and Canada finds. About 40 percent of officers surveyed reported sleep disorders, with various health implications.
Harvard researchers say they've uncovered a big problem among the nation's 700,000 police officers: a serious lack of sleep.
In what's believed to be the first study of its kind, the researchers queried nearly 5,000 municipal and state police officers in the U.S. and Canada about their sleep habits and symptoms of possible sleep disorders. Then they assessed their on-duty performance for two years.
Forty percent had sleep disorders, and the vast majority of these were undiagnosed before.
Ireland is ranked second followed by Australia, New Zealand and the U.K. Charities Aid Foundation used Gallup's Worldview Poll to look at three behaviors: "giving money, volunteering time and helping a stranger."
The U.S. came out on top after being ranked fifth last year.

Mexican soldiers at a ceremony in Ciudad Mier on Dec. 8. The military and other branches of the security forces have now battled the cartels for five years. While most of the violence is blamed on the cartels, human rights groups say the security forces have also been linked to abuses.
In Mexico, the last five years of President Felipe Calderon's drug war have been marked by brutal violence, unsolved kidnappings and tens of thousands of deaths. Most of violence has come from the drug gangs, but some of these atrocities have been committed by the Mexican military and police.
Human rights groups say that as state security forces battle the drug cartels, they've tortured, abducted and killed criminal suspects and even innocent civilians.
