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.

I admit I was biased against the Margaret Thatcher biopic The Iron Lady. Not, you understand, against Thatcher and her Tory politics. Against Meryl Streep and her accents. Which are great, no doubt. But I went in resolved not to fall for her pyrotechnics yet again. I wanted realism.

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.
