Think you know how to avoid overeating? Think again.

Research suggests that choices, like how much to eat during a meal, are often made subconsciously. Trouble is, our brains are hard-wired to mislead us in lots of little ways, which can have a big impact on our diets.

Take the Delboeuf effect, an optical illusion first documented in 1865. It starts with two dots of equal size. But surround one dot with a large circle and the other dot with a small one, and suddenly the second dot looks bigger.

NBC's new drama, Smash, plumbs the drama behind the curtain. The series is the story of a Broadway musical — from the first idea, to auditions, rehearsals and the big premiere.

Theresa Rebeck is the show's creator and executive producer. She's also a screenwriter, playwright and a Broadway veteran — with a hit play "Seminar," that's now on Broadway.

Rebeck tells Weekend Edition host Scott Simon that Smash is a "workplace drama — it's just that the workplace is a musical."

British writer Penelope Lively was in her late 30s before she began her career writing children's books. Now, four decades and 20 works of fiction later, she has just released the novel How It All Began, in which she explores the capricious role that chance plays in our lives.

Lively's lifetime habit of storytelling began when she was growing up in Egypt during World War II. She spent a lot of time alone and amused herself by making up stories, which often involved embellishing the classics with her own personal touch.

After his second-place finish in the South Carolina primary, Mitt Romney arrived in Florida armed with money and organization. He's used both to stop Newt Gingrich's momentum. With three days until the primary, polls give Romney a solid lead over Gingrich in Florida.

Florida is a big state, but Romney and Gingrich's paths have crossed often this week. There were the two debates, and in Miami, like Gingrich, Romney spoke to the Hispanic Leadership Network Friday.

You wouldn't necessarily think of a cancer support group as a place where teens meet and fall in love — but that's exactly what happens to Hazel and Augustus, the young protagonists in The Fault in Our Stars, the latest from author John Green.

Hazel is 16 — she has thyroid cancer with a "satellite" in the lungs that makes her feel like she's drowning. Augustus, or Gus, is a little older, lithe and handsome. He's lost a quarter of a leg to cancer but tells people, "I'm on a roller coaster that only goes up."

In Mexico, where criminals are armed to the teeth with high-powered weapons smuggled from the United States, it may come as a surprise that the country has some of the most restrictive gun laws in the world.

Law-abiding Mexicans who want a gun to defend themselves have no good options. Either they fight government red tape to get a legal permit, or they buy one on the black market.

After an outbreak of violence, one embattled community in northern Mexico called Colonia LeBaron has begun to ask if it's time for the country to address its gun laws.

Politics may be show business for ugly people, but you don't have to be ugly about it yourself.

It's become a cliche to describe the endless series of Republican presidential debates as a reality show. But lately a lot of politicians have been acting as though they were looking to secure a spot on the "now trending" lists of Internet search engines.
