More than 13,000 years ago, hairy elephant-like creatures with giant tusks roamed North America. These mastodons were hunted by some of the earliest people to live here, and scientists recently learned a bit more about those mysterious cultures by taking a new look at an old mastodon bone.
Mitt Romney's current run for the White House has not included a big presence in the first state that will actually vote: Iowa, which holds its caucuses on Jan. 3.
He failed to meet expectations at the Iowa caucuses in 2008. So for 2012, his campaign has focused instead on New Hampshire as the key to a series of primary victories that, they believe, will result in the former Massachusetts governor winning the GOP nomination.
Moammar Gadhafi was killed in the crossfire of a battle between his supporters and fighters loyal to the opposition that topped the dictator's regime, Libya's interim prime minister told NPR this afternoon.
"Nobody can tell if the [fatal] shot was from the rebel fighters or from his own security guard," Interim Prime Minister Mahmoud Jibril told All Things Considered host Robert Siegel.

Their mission: Find out what would happen if Franchy sat at the front of the bus.
Nelly Lambert is a PhD student in English at Catholic University. She's writing her dissertation on Emily Dickinson's poetry.
Poet Emily Dickinson withdrew from society for most of her adult life. And yet, she was known to lower a basket full of cakes from the window of the home she rarely left to crowds of expectant children on the street below. Dickinson probably never met these children, yet she connected with them through her baking.
The killing of Col. Moammar Gadhafi will most certainly go down as one of the important chapters of what's come to be known as the Arab Spring, or the popular uprisings across North Africa and the Middle East that have deposed three dictators.
In the region, one big question that will be answered in the coming weeks is how Gadhafi's killing will affect the opposition movements firmly in place in Syria and Yemen.
NPR's Ahmed Al-Omran, a production assistant on NPR's social media desk, has been sifting through social networks to gauge reaction from the region.
