All Things Considered

Connecticut's chief medical examiner, Wayne Carver, has raised the possibility of requesting genetic tests on Adam Lanza, the man responsible for the shootings at Sandy Hook Elementary School.

Carver hasn't said precisely what he may want geneticists to look for, but scientists who study the links between genes and violence say those tests won't reveal much about why Lanza did what he did.

Long before President Obama nominated John Kerry as the country's top diplomat, the Massachusetts senator was seen as a secretary of state in waiting.

He has been chairman of the Senate Foreign Relations Committee and has frequently jetted off to Afghanistan and Pakistan whenever the Obama administration needed him.

House Speaker John Boehner's alternative plan to the automatic tax hikes set to take effect at year's end fell short of enough votes to pass. The bill would have placed a higher tax rate on income over $1 million a year.

Since the mid-1980s, the U.S. Border Patrol has quintupled in size — growing from about 4,000 to more than 20,000 agents.

The government has constructed some 700 miles of fencing and vehicle barriers. It has placed thousands of ground sensors, lights, radar towers and cameras along the border. And Customs and Border Protection is now flying drones and helicopters to locate smuggles and rescue stranded immigrants.

So here's the question: Is the Southwest border secure?

House Republicans are under a lot of pressure.

House Speaker John Boehner and his leadership team are urging them to support his "Plan B" to avoid the automatic tax hikes of the "fiscal cliff." But they're also facing pressure from outside groups that could mount primary challenges against them if they do.

Boehner argues his plan — which would allow the Bush-era tax cuts to stay in place for income under $1 million a year — isn't a tax increase. But a number of conservative groups have come to a very different conclusion.

There are 760 million Christian children in the world, according to the Pew Research Center. Suppose Santa delivers one gift to each child. What kind of delivery workforce would Santa need?

We couldn't get an interview with Santa. But we did get Paul Tronsor from FedEx and Mike Mangeot from UPS. They helped us go through the numbers.

Here are just a few of the positions Santa would need to fill to pull off Christmas. (Note: For the complete list, see the graphic at the bottom.)

The bare facts of Homeboy Sandman's back story don't sound very hip-hop: prep school in New Hampshire, Ivy League B.A., even some pieces for The Huffington Post. But, as is often the case with class and race in America, bare facts don't tell the whole story.

The wildly popular photo-sharing site Instagram nearly caused a user revolt when it revamped its terms of service and privacy policy to suggest it could allow uploaded photos to be used in ads without users' permission.

The change — which was posted in dense legalese on its website Monday — sparked users to vow to stop posting their color-filtered, tilt-shifted photos to Instagram.

"Everyone calls me Geppetto," announces Lou Nasti. "I mean, look at me: The glasses, the gray hair — and I play with dolls. Come on."

The gang rape of a young woman on a bus in Delhi has touched off outrage and soul-searching in the increasingly unsafe Indian capital.

Spontaneous protests have erupted, while anguished members of Parliament decried the attack.

This time of year, many are thinking about giving to one charity or another and wondering just how much good their donations will do.

Ask the average person — even in Washington — who serves as President Obama's chief of staff and you'll probably get a blank stare.

Jack Lew hasn't been heard or seen in the "fiscal cliff" drama unfolding between the White House and Congress. But the former budget director, who took over the top White House job last January, has become a key player behind the scenes.

Global efforts to combat malaria are under threat from new strains of drug-resistant malaria, which are cropping up in Southeast Asia.

Over the last decade, the number of malaria deaths around the world has dropped sharply, from just over 1 million in 2000 to roughly 600,000 last year.

Much of that progress is due to the widespread use of drugs containing artemisinin. The new malaria drugs quickly kill the parasite.

As President Obama spoke to mourning families in Newtown, Conn., on Sunday night, he clearly seemed to suggest a need for tougher gun laws.

"Are we really prepared to say that we're powerless in the face of such carnage? That the politics are too hard?" he said.

For Congress, the politics have been too hard.

The combination of a powerful gun owners' lobby in the form of the National Rifle Association and a loss of public support for gun control has stymied efforts in recent years to tighten gun laws.

Inside a modest storefront in Loxley, Ala., 18-year-old Maria Lola Melisio points out the Mexican spices and other products for sale in her mother's market.

"There are the leaves where you make your tamales — you roll them up in that," she says.

Melisio has long dark curls and is wearing a houndstooth scarf in support of the Alabama Crimson Tide. When she was 7 years old, she entered the U.S. illegally from Mexico with her mother, and still has a scar on her back from crawling under the border fence. It's a story she's kept secret until now.

The literary world was abuzz this year with the runaway success of "Fifty Shades of Grey" and J.K. Rowling's books for grown-up muggles. But it was Pulitzer Prize-winning novelist Philip Roth's retirement that got the attention of commentator Ben Dolnick.

BEN DOLNICK: This fall, in an interview with a French magazine, Philip Roth announced his retirement. I no longer have the stamina to endure the frustration, he explained. Instead, he's been entertaining friends, playing with his iPhone, and eating meals prepared by a personal chef.

It's probably not true that truth is stranger than fiction, but in the hands of a great biographer, it can be just as compelling. Novelists can create unique and unforgettable characters — there's never been anyone quite like Jane Eyre or Ignatius J. Reilly — but there's no shortage of fascinating literary protagonists who just happened to exist in real life.

GUY RAZ, HOST:

It's WEEKENDS on ALL THINGS CONSIDERED, from NPR News. I'm Guy Raz. Yesterday on the program, we spoke with pastor and poet Eugene Peterson. He's retired now, but he was the pastor at Christ Our King Presbyterian Church - near Baltimore - for 30 years. Back in the 1990s, he began to translate the Bible into modern-day English. It became the best-selling book called "The Message." It's a book millions of Christians and non-Christians alike, have come to rely on.
