Thousands of messages posted on the Internet every day in China get censored. Until now, little has been known about how the Chinese censorship machine works — except that it is comprehensive.
"It probably is the largest effort ever to selectively censor human expression," says Harvard University social scientist Gary King. "They don't censor everything. There are millions of Chinese [who] talk about millions of things. But the effort to prune the Internet of certain kinds of information is unprecedented."
It's 8 a.m. on a recent day at Forward Operating Base Nolay, a small Marine outpost in Taliban-infested Sangin District of southern Afghanistan's Helmand province. The Marines are in the process of caffeinating and preparing for the day.

Look in the mirror and you won't see your microbiome. But it's there with you from the day you are born. Over time, those bacteria, viruses and fungi multiply until they outnumber your own cells 10 to 1.
As babies, the microbes may teach our immune systems how to fight off bad bugs that make us sick and ignore things that aren't a threat.
We get our first dose of microbes from our mothers, both in the birth canal and in breast milk. Family members tend to have similar microbiomes.
Of all the world's birds, perhaps none are more mystical than cranes.
From Asia to North America, these tall birds with haunting cries have been woven into paintings, literature and folk tales. But today, 10 of the world's 15 crane species are threatened, and some are on the brink of extinction.
Their grass and wetland habitats are devastated all over the world. The International Crane Foundation, based in Wisconsin, has been studying and advocating for the birds for 40 years. George Archibald founded it with another young ornithologist on a family farm near Baraboo.
Diana Nyad's successful swim from Cuba to Key West on Monday was made all the sweeter because she had tried — and failed — four times before.
She learned you should "never, ever give up," but she also learned some practical lessons to help beat the elements in those earlier attempts. Out of failure, she innovated. And out of innovation, she succeeded.
If you're just joining us, this is WEEKENDS on ALL THINGS CONSIDERED from NPR News. I'm Jacki Lyden. Coming up, the art of embracing failure.
But first, reading and learning have been enshrined in Baghdad's storied libraries for centuries. Some were destroyed by Mongol invaders hundreds of years ago, but more recently, the war in Iraq savaged the country's libraries. Looting and burning left many of them emptied of books and patrons.
