When anthropologists tallied the use of emotional words through a century of literature, they included many books without clear emotional content — technical manuals, for example, and automotive repair guides.

Researchers were able to chart historical periods of positive and negative moods through literature. Values above zero indicate generally "happy" periods, and values below the zero indicate generally "sad" periods.
Were people happier in the 1950s than they are today? Or were they more frustrated, repressed and sad?
To find out, you'd have to compare the emotions of one generation to another. British anthropologists think they may have found the answer — embedded in literature.
Several years ago, more or less on a lark, a group of researchers from England used a computer program to analyze the emotional content of books from every year of the 20th century — close to a billion words in millions of books.
The home of Kaufman County District Attorney Mike McLelland is surrounded by police tape in Forney, Texas, on Monday. Authorities launched a massive investigation into the weekend killings of McLelland and his wife.
Two county prosecutors fatally shot in Texas. Colorado's top prison official gunned down. And a dozen more members of the U.S. justice community — ranging from police to judges — victims of targeted killings since the beginning of the decade.
There's a reason President Obama chose Colorado to hold a rally this Wednesday in favor of gun control.
Among the states this year, Democratic-controlled Colorado has passed the toughest new restrictions on gun rights, requiring universal background checks and banning magazines that hold more than 15 rounds of ammunition.
But if certain liberal wishes have come true in Colorado — recall that it was one of two states last fall that voted to legalize marijuana — things look very different next door in Kansas.

Say your one-month-old baby is spitting up and crying a lot. Your usual bag of infant-soothing tricks hasn't worked, and you're worried that there's something wrong with her.
So you head to the pediatrician, who tells you that your otherwise healthy child has gastroesophageal reflux disease, or GERD. Would receiving this medical diagnosis make you more interested in giving her drugs than if you never heard the word "disease"?
The United States has sent two F-22 Raptor fighter jets to take part military drills in South Korea, a move that is meant to show U.S. commitment to the defense of the region from its North Korean neighbor, a Pentagon spokesman told the Associated Press.
Also on Monday, South Korean President Park Geun-hye appeared to give her country's military permission to strike back at any attack from the North.
