It's been a mixed year for Alzheimer's research. Some promising drugs failed to stop or even slow the disease. But researchers also found reasons to think that treatments can work if they just start sooner.

Scientists who study Alzheimer's say they aren't discouraged by the drug failures. "I actually think it was a phenomenal year for research," says Bill Rebeck, a brain scientist at Georgetown University.

Brazilian health officials say an epidemic is taking hold — an outbreak of crack cocaine use nationwide, from the major cities on the coast to places deep in the Amazon.

It's an image at odds with the one Brazil wants to project as the country prepares to host soccer's World Cup in 2014 and the Summer Olympics two years later. But the problem has become too big to ignore.

Some airlines — especially the smaller ones — worry they won't have enough pilots. They're a number of factors in play, but they point to new federal safety rules as a big part of the problem.

In February 2009, a Colgan Air commuter jet crashed, killing 50 people. Investigators cited inadequate pilot training; Congress responded with new legislation.

Managing food allergies can be a pain, requiring lots of sleuthing of ingredients in restaurants and supermarkets. But people with potentially lethal allergies to nuts and other foods don't have much choice.

As the nation's first African-American president, Barack Obama benefited from and expanded his party's enormous advantage among minority voters.

But as he prepares to start his second term, Obama hasn't managed to usher in behind him many Democrats who are minorities to top elected office. Conversely, Republicans — despite their highly limited support among non-Anglo voters — have managed to elevate more top politicians from minority backgrounds.
