There is a remarkable change going on in Mogadishu, Somalia — often dubbed the world's most dangerous city. For starters, it may not deserve that title anymore.

Last year, African Union forces drove the Islamist militant group al-Shabab out of Mogadishu. Now, Somalia has a new president and prime minister who have replaced the corrupt and unpopular transitional government.

Marijuana legalization is back on the ballot this year. California voters defeated a legalization proposal in 2010, but now similar measures have cropped up in three more Western states. This time around, some of the most intense opposition is coming from the earlier pioneers of legalization — the medical marijuana industry.

As part of NPR's coverage of this year's presidential election, All Things Considered asked three science reporters to weigh in on the race. The result is a three-part series on the science of leadership. In Part 1, Alix Spiegel looked at the personalities of American presidents.

Food appears so often and takes on so much importance in Jami Attenberg's novel The Middlesteins, that while reading it I sometimes felt like I was on a kind of literary cruise ship. But excess isn't presented here wantonly; instead, it's laid out and explored with sympathy, thought and depth. Early on, the parents of the main character think, "Food was made of love, and was what made love, and they could never deny themselves a bite of anything they desired." And so the novel takes off from the evocative starting point known as appetite.

Even if you didn't watch any of the three presidential debates, chances are you're familiar with Big Bird, binders and bayonets.
