Great works of art have come to the streets of Detroit as part of a new exhibition called Inside/Out. Proving that art can also be enjoyed outside of museum walls, The Detroit Institute of Arts has brought life-size reproductions of famous masterpieces to the streets, parks and concrete facades of Detroit. This is the second year for the Inside Out project, following its initial success in 2010. But this year, the Institute expanded the program to include more communities, and even more classic paintings.

One in six Americans are poor, which means 50 million people are living in poverty in the United States. Dr. Cornel West and Tavis Smiley, hosts of PRI's "Smiley and West," went on "The Poverty Tour: A Call to Conscience," an 18-city tour of the United States in August, to speak with Americans living in poverty and get a sense of what it's like to be poor in America today. This week, PBS will air the first of five episodes of "The Poverty Tour."

Today is Columbus Day, a federal holiday commemorating Christopher Columbus, the Italian explorer who famously landed on American soil in the Bahamas on October 12, 1492, after spending over two months sailing from Spain. His voyage across the Atlantic prompted many other explorers to follow suit, eventually opening the doors to settlement and trade between North America and the rest of the world. Many people disagree, however, with applying the word "discovered" to Columbus's landing in America, and others criticize him for his cruelty toward Native Americans, and insist that he doesn't deserve a holiday.

The Royal Swedish Academy of Sciences announced that American economists Thomas J. Sargent and Christopher A. Sims will be awarded this year's Nobel Prize in economics this morning. University of Chicago professor Roger Myerson won the prize in 2007 for his contribution to the mechanism design theory, which allows economists to identify efficient trading mechanisms, regulation schemes, and voting procedures to keep markets vibrant. Myerson discusses what the honor means both personally, and to the field of economics.
