FLORA LICHTMAN, HOST:

Next up, a case of life imitating art. A few months ago, we talked to writer Barbara Kingsolver about her latest book, "Flight Behavior." The book is a fictional account of an ecological disaster in the making, and the fate of millions of monarch butterflies is at the center of the plot. Would the species survive? That's the art part.

This is SCIENCE FRIDAY, I'm Flora Lichtman, filling in for Ira today. You know the phrase you are what you eat? Well, new research suggests a slight modification: Your gut bacteria are what you eat. And if you eat more red meat, for example, you'll nurture populations of microbes that like to eat red meat, too, which might not seem like a bad thing except that researchers have pinpointed a compound in red meat called L-carnitine that when broken down by gut bacteria might contribute to heart disease.

FLORA LICHTMAN, BYLINE: Up next, another mover and shaker in the alimentary canal - coffee. Whether you're a home brewer or a latte devotee, whether you take it light and sweet or on ice, your coffee is guaranteed to be chock full of chemistry. It starts in the bean, which is actually not a bean at all.

It's a seed, according Harold McGee, author of "On Food and Cooking: The Science and Lore of the Kitchen" along with other books on science and food. And we caught up with Harold, to hear more about how coffee gets its signature taste.

NEAL CONAN, HOST:

This is TALK OF THE NATION. I'm Neal Conan in Washington. In late 2011, four teenage boys at a party allegedly raped a 15-year-old girl in Nova Scotia. A picture of the incident circulated among classmates and then went viral. In a Facebook post, the girl's mother said she'd been shunned by her friends, bullied and called a slut. She moved, transferred schools, made new friends, started therapy, but a week ago Rehtaeh Parsons hanged herself. Her family took her off life support this past Sunday.

NEAL CONAN, HOST:

In this day and age, interfaith marriage doesn't seem like that big a deal. They represent close to half of all marriages in this country over the past 10 years. The decision can also come with a price, though: disagreement on how to raise children and higher rates of divorce. There are benefits, as well, according to Naomi Schaefer Riley, author of "Til Faith Do Us Part: How Interfaith Marriage is Transforming America." She'll join us in just a moment.

Names are possessions that we carry with us all our lives. But we seldom think about what goes into picking the right one. Some choose to change their first names in adulthood, because of family history or pure disdain for a moniker. For Silas Hansen, the reason was that he's transgender.

This is TALK OF THE NATION. I'm Neal Conan in Washington. Country star Brad Paisley released a new album today, not usually something that becomes a national news item. But one song on "Wheelhouse" is generating conversation even before most people get a chance to hear it.

"Accidental Racist" is a collaboration with rapper LL Cool J. Brad Paisley sings of a Southern white man in a Starbucks who believes he's being judged for the Confederate battle flag on his T-shirt and responds with an appeal for understanding.

This is TALK OF THE NATION. I'm Neal Conan, in Washington. Over the past few weeks, a white supremacist prison gang called the Aryan Brotherhood of Texas has emerged as one of the groups that may have had a motive to murder two prosecutors in Kaufman County. While any connection to those crimes is speculative at this point, there are stronger links between another white supremacist gang called the 211 Crew and the murder of Tom Clements, the head of Colorado's prison system, last month.

The North Korean government officially suspended operations at the Kaesong industrial complex, withdrawing all of its more than 50,000 workers. Many see the complex as the last remaining symbol of North and South Korean unity and fear that tensions may be nearing a dangerous tipping point.

IRA FLATOW, HOST:

This is SCIENCE FRIDAY, I'm Ira Flatow. Earlier this week, the New York Times reported new CDC data on diagnosis of attention deficit hyperactivity disorder, ADHD, in kids. And the numbers are startling, with 11 percent of the parents surveyed reporting a diagnosis of ADHD for their school-age kids, higher numbers for some sub-groups of age and gender. That's a big jump. Estimates before that had been that ADHD affected somewhere from three to seven percent of children.

IRA FLATOW, HOST:

You know, one of the first ideas drilled to you as a sort of a foreign idea to you as a kid is that life is not fair. How come she got a pony for her birthday, I got a goldfish, something like that? Yeah, right, yeah. but where did we even get the sense of what's fair and what's not, of what's right, what's wrong, our sense of justice?
