If you play today's massively multiplayer online role-playing games — World of Warcraft or Final Fantasy, for example — you have a 1970s tabletop game to thank, says author Michael Witwer.

Witwer has just written a biography of Gary Gygax, the co-creator of Dungeons & Dragons.

"Even first-person shooters like Call of Duty have some of the roots at least in tabletop role-playing games," he tells NPR's Ari Shapiro.

The World Health Organization made an announcement Monday that's likely to come as a blow to anyone whose favorite outdoor snack is a hot dog.

Processed meats — yes, hot dogs, plus sausage, ham, even turkey bacon — are cancer-causing, a committee of scientists with WHO's International Agency for Research on Cancer concluded. And it classified red meat as "probably carcinogenic to humans."

"The Unicode Consortium" may sound like the dark cabal of villains in a James Bond movie. And though they aren't plotting world domination in a volcano lair, they do hold a lot of power — over your text messages.

What would you do if a stranger stopped you on the street, asked to take your picture and asked to hear your story?

For the past five years, photographer Brandon Stanton has been doing exactly that — on the streets of New York, no less — and thousands of people have said yes. Stanton has been not only collecting their stories and images, but also sharing them on his blog, Humans of New York.

Anheuser-Busch, the company behind both Budweiser and Beck's, has agreed to settle a class-action lawsuit. The plaintiffs claim the megabrewer misled customers by trumping up Beck's German roots and insinuating that it was an imported beer.

Oprah Winfrey lifts the popularity of almost anything she embraces. On Monday, Weight Watchers announced that the billionaire media mogul would be giving it her midas touch by acquiring a 10 percent stake in the diet company.

Winfrey will join the board and will lend her name and image to Weight Watchers marketing. Shares of the company more than doubled by the end of the day.

Secretary of State John Kerry stepped before a packed auditorium Thursday. He was at Indiana University for the opening of a school of international studies.

"I have managed to completely forget that when running for president in 2004, I was crushed in Indiana," he quipped.

Kerry was welcomed Thursday as he promoted the Obama administration's recent international agreements, like deals on Pacific trade and Iran's nuclear program.

From floating old food in Jell-O molds to casseroles to cold pizza, the way we reuse and eat leftovers in America is special.

And it turns out that if you track our relationship with leftovers over time, you will understand a lot about our economy and how we live.

In mid-November, diners at the New York restaurants Gramercy Tavern and The Modern may notice something new on their menus: higher prices, across the board.
