On-air challenge: Every answer is a two-word phrase in which the letter "O" is added at the end of the first word to make the second word. For example, given the clue "pack animal owned by Thomas Jefferson's first vice president," the answer would be "Burr burro."
Last week's challenge: Draw a regular hexagon and connect every pair of vertices except one. The pair you don't connect are not on opposite sides of the hexagon but along a shorter diagonal. How many triangles of any size are in this figure?
The race for the Republican nomination of 1860 was one of the great political contests of American history. It was Abraham Lincoln versus Salmon Chase, versus William Seward.
Author Walter Stahr spoke with Weekends All Things Considered host Guy Raz about his new biography, Seward: Lincoln's Indispensable Man. He describes how a man who was Lincoln's fiercest and most critical opponent eventually became his most loyal and trusted adviser.
Falafel — those crispy, filling fried balls of mashed beans, herbs and spices — is found in cafes and homes all over the Middle East and parts of Africa. It's like a common language shared among sometimes fractious nations.
But until recently, I always thought falafel was made one way — garbanzo beans, onion, garlic, parsley, cilantro and cumin. (That's how my Sudanese mother taught me.) But it turns out there are many recipes out there, each with a flavor distinct to its region.

It's the subject of Feinstein's new memoir, The Gershwins and Me: A Personal History in Twelve Songs. (A CD of Feinstein singing those songs also comes with the book.)
Ben Affleck's Argo is two-two-TWO movies in one, and while neither is especially original, by merging them Affleck pulls off a coup. First, he gives you espionage with the You Are There zing of a documentary. Then he serves up broad showbiz satire. For his final feat, he blends the two into a pulse-pounding nail-biter of a climax. And this all really happened. Most of it. Except for that climax.
