Journalists make for a pretty tough crowd.

There were lots of comments on this blog regarding my recent stories about making salads safer. Many of those comments argued that the solution is to grow your own. Or at least buy from local farmers.

Which raises an interesting question: Are salad greens from your local farmer's market actually safer than packaged lettuce from thousands of miles away? And should the same safety rules apply to both?

The new issue of The Atlantic asks: Is Facebook Making Us Lonely? The jury's out, though signs point to maybe.

Facebook didn't necessarily make Tanja Hollander lonely, per se, but it did make her curious. It was a little over two years ago when she looked at that number representing "friends," 626 in her case, and started to analyze it.

Six men wearing bright orange prison jumpsuits appeared in a D.C. courtroom today, seeking to overturn their decades-old convictions in a brutal murder by arguing the Justice Department failed to turn over critical evidence that could have helped them assert their innocence.

The trustees in charge of nation's Social Security program said a sagging economy has hit the program hard. The program's trust fund, which goes mostly to retirees, said the trustees, will run dry by 2033.

The AP reports "Medicare's finances have stabilized but the program's hospital insurance fund is still projected to run out of money in 2024."

Mitt Romney on Monday endorsed the idea of extending a law that curbs interest rates paid by some recipients of federal student loans, a cause that President Obama has made a campaign issue.

It's hard out there for a college grad.

The AP analyzed government data and came up with this stunning figure: "Half of young college graduates [are] either jobless or underemployed in positions that don't fully use their skills and knowledge."

The whole story is worth a read, so we encourage you to click over, but here is the meat of the AP's analysis:

President Obama announced a set of new sanctions that target "Syria and Iran and the 'digital guns for hire' who help them oppress their people with surveillance software and monitoring technology," the AFP reports.

The president made the announcement during a visit to the Holocaust Memorial Museum in Washington. His visit was the first as president.

The forces on the unmanned hypersonic glider tested last summer by the U.S. Defense Advanced Research Projects Agency (DARPA) were so great that large parts of its skin peeled off causing its emergency system to plunge it into the ocean.

As we reported last August, the Falcon HTV-2 "was shot up on a rocket and right at the edge of space, it separated and glided through the atmosphere at 13,000 mph."

Activist Van Jones served as special adviser to President Obama on green jobs. He resigned in 2009 after media reports questioned his beliefs about the 9/11 attacks. Now, Jones is back with a new book, Rebuild the Dream, outlining his vision for the progressive movement. He speaks with host Michel Martin.
