Earlier this week, we were surprised to learn that food manufacturers increasingly X-ray foods to screen for foreign objects that can break a tooth. That sounds like a good idea.
But the notion of X-rayed food also sparked a lively debate in The Salt's comments section on whether this poses a health threat. After all, we do know that some X-rays can damage DNA in the human body. So what does radiation mean for food?

An investigating officer has recommended that Army private Bradley Manning face court-martial on multiple criminal charges related to the downloading of nearly 1 million war logs and secret diplomatic cables. Manning is accused of taking the files and them passing them on to WikiLeaks.
If he does face a court martial and is convicted, he could be sentenced to life in prison.

AUDIE CORNISH, HOST:
And I'm Audie Cornish. Today at noon, America's oldest working clock tower rang out for the first time since the 1800s.

CORNISH: Old South Meeting House in Boston was a Puritan gathering place. Ben Franklin was baptized there and the Boston Tea Party was planned there, but the belfry has been silent since 1876, after the brick building was nearly destroyed in the great Boston fire.
CORNISH: Earlier this week, we remembered the pianist Alexis Weissenberg, who died Sunday at the age of 82. He was known for the precision of his playing. One critic even called it chillingly scientific. But pianist Kirill Gerstein, who knew him well, told us that Weissenberg was just the opposite.
KIRILL GERSTEIN: I think he was not at all cold, neither as a person nor as a musician. I think there was a burning intensity that you could always sense.
The Internet Corporation for Assigned Names and Numbers, known as ICANN, is forging ahead with plans to sell new domain categories despite vocal opposition. The decision raises questions about who should govern the Internet.
Aides say President Obama won't get deeply involved in the political campaign until Republicans settle on a nominee, but Mr. Obama has already been busy fundraising. Today, his campaign announced that it raised $130 million last year. And as NPR's Scott Horsley reports, even when the president is conducting his official duties, it's easy to sense the political subtext.
An Indian street dweller prepares food on the streets of Kolkata. A growing number of scientists say that reducing black carbon — mostly soot from burning wood, charcoal and dung — would have an immediate and powerful impact on climate.
Politically, climate change is off this year's campaign agenda. Jobs, the economy and social issues are front and center.
But scientists are working as hard as ever to figure out how much the Earth is warming and what to do about it. Some now say it's time for a new strategy, one that gets faster results.
Talk to Durwood Zaelke, for example. Zaelke is a grizzled veteran of the climate wars: He was in Kyoto in 1997 when the world's nations drafted a treaty promising to curb warming, and he has watched that promise fizzle while the planet's temperature continues to rise.
