Tax policy has been a divisive theme throughout the presidential campaign. At the core of the debate are divergent philosophies about what the economy needs — and how to get it.
In this Oxford-style debate from Intelligence Squared U.S., a panel of experts dissects the motion "The Rich Are Taxed Enough." The term "enough," in this case, is determined by three factors: fairness, sufficiency and efficiency.
A new NPR poll shows the outcome of the Nov. 6 election is too close to call. Mitt Romney leads President Obama nationwide; Obama leads Romney in key battleground states. Both leads are within the poll's margin of error.
The latest and last NPR Battleground Poll for 2012 shows former Massachusetts Gov. Mitt Romney holding the narrowest of leads in the national sample, but trailing President Obama in the dozen states that will decide the election.
The poll adds evidence that the Oct. 3 debate between the two men redefined the race. But the movement toward Romney that emerged after that night in Denver also seems to have stalled after the race drew even — leaving the outcome difficult to call.

Doug Smith and his girlfriend Trenor Bender thought the worst of Hurricane Sandy had passed them by when they looked out the windows in the wee hours today. At their rental home, three rows back from the beach in Kitty Hawk, North Carolina, there was no water in the yard at all at 3:30 this morning. But that didn't last.
"When I woke up, I couldn't believe it," says Smith of the view just a few hours later, "I saw this sheet of water on the ground."
Cray employees put the finishing touches on Titan at the Department of Energy's Oak Ridge National Laboratory in Tennessee. The supercomputer may be the world's fastest. It's designed to do 20 petaflops — or 20,000 trillion calculations — each second. It consumes enough electricity to power a small city of 9,000 people.

The Nvidia Tesla K20 GPU Accelerator powers the new Titan supercomputer. Its design is based on chips built for gaming.
The world's fastest supercomputers have come back to the U.S. In June, the title was claimed by a machine named Sequoia at Lawrence Livermore Labs. Monday, at the Department of Energy's Oak Ridge National Laboratory, what could be an even faster computer comes online. It's called Titan and it would not have been possible were it not for the massive market for video games.

There's big news in the world of publishing: The two conglomerates that own Random House and Penguin announced Monday that they were merging their book businesses to form a new company.
German media company Bertelsmann, the owner of Random House, will own 53 percent of the new firm, Penguin Random House; Pearson, which owns Penguin, will control the rest. The merger, subject to regulatory approval, is scheduled to be completed in the second half of 2013.
