When Facebook engineer Arturo Bejar observed users were reporting pictures of themselves, not those with illegal content, he recognized the need for a better way for users to resolve internal conflicts. Bejar talks about how Facebook is trying to encourage compassion in online social interaction.

A major medical group issued ethical guidelines on Monday that take the provocative position of urging doctors to consider cost-effectiveness when deciding how to treat their patients.

The American College of Physicians, the second-largest U.S. doctors' group after the American Medical Association, included the recommendation in the latest version of its ethics manual, which provides guidance for some 132,000 internists nationwide.

We knew defense cuts were coming, but The New York Times is reporting that Defense Secretary Leon Panetta will unveil $450 billion in cuts this week. With the announcement, reports the Times, will also come a new philosophy for the Pentagon.

The Times reports:

On the last day he'll have New Hampshire to himself, GOP presidential candidate Jon Huntsman, who bypassed the Iowa caucuses, plans to travel from Pembroke to Peterborough in search of enough votes to break into the top three in next week's Granite State primary.

With his presidential opponents scrambling for last-minute support in advance of Tuesday's Iowa caucuses, Huntsman has been methodically wooing New Hampshire voters in nearly 150 events over the past few weeks.

Most everyone's spirits are a bit deflated after the holidays. So, as a literary antidote, I recommend a just-published anthology called New York Diaries: 1609 – 2009. Editor Teresa Carpenter has collected four centuries worth of diary excerpts written by people, great and small, who've lived in or just passed through one of the greatest cities in the world.

Make a list of the world's most popular scientists, and Stephen Hawking's name will be near or at the very top of the list.

Hawking, the author of A Brief History of Time and a professor at the University of Cambridge, is known as much for his contributions to theoretical cosmology and quantum gravity as for his willingness to make science accessible for the general public, says science writer Kitty Ferguson.

"It's not dumbing down [science]; it's really making it accessible, hopefully, to a lot of people," she tells Fresh Air's Terry Gross.

In yet another sign that the economy is limping forward, the Commerce Department said today that spending on construction rose 1.2 percent in November for the third time in four months.

Candidates Make Last Push Before Iowa Voting Begins

Jan 3, 2012

Republican presidential candidates prepared Tuesday for their first major test of the primary season, making last-minute whistle-stops throughout Iowa in hopes of swaying many undecided caucus-goers.

Later tonight, Iowa Republicans will gather to cast ballots for the person they want to stand against President Obama in November. But after a bruising months-long campaign, more than a third of those participating in the caucuses say they still haven't made up their minds.

If you were listening carefully to NPR's Ted Robbin's report on Rick Santorum on Morning Edition, yesterday, you heard some pretty controversial comments from the Republican presidential candidate.

Ahmed Kathrada spent decades in jail with Nelson Mandela, then spent the first years of democracy helping to shape the country's government after the fall of apartheid. The 87-year-old Kathrada died in Johannesburg on Tuesday morning.

Friends and strangers alike called Kathrada by the nickname Kathy, which was bestowed on him by his eighth-grade teacher, who was Afrikaans, a member of the white minority descended from Dutch colonists.
