Turkish police in Istanbul used tear gas and water cannons to break up what are being described as the worst anti-government protests in years.

The top two surviving leaders of Cambodia's genocidal Khmer Rouge regime have expressed remorse for their actions while in power and acknowledged a degree of responsibility for the atrocities committed in their names.

Nuon Chea, the chief lieutenant of Khmer Rouge leader Pol Pot, and Khieu Samphan, who acted as head of state for the Maoist regime, are currently on trial for genocide and crimes against humanity.

The Transportation Security Administration has told Congress that it's finished retrofitting airport scanners to blunt a widely criticized technology that shows graphic detail of a passenger's body as he or she goes through security checkpoints.

It might come as a surprise that for centuries the French have been sans a term for "French kiss."

But, voila! The newest edition of the Petit Robert 2014 dictionary has rectified that with a new verb — "galocher," meaning "to kiss with tongues." It's a clever derivation of la galoche, a word for an ice-skating boot, and so evokes the idea of sliding around the ice — or the lips and tongue.

The father of the Chechen immigrant who was killed in Florida during an FBI interrogation over his ties to one of the Boston Marathon bombing suspects says his son was killed execution-style.

At a news conference in Moscow, Abdul-Baki Todashev showed reporters 16 photos he said were of his son, Ibragim, in a Florida morgue.

Move over Archaeopteryx, an older bird just landed on the evolutionary tree.

Police in France say that a 21-year-old Muslim convert who confessed to stabbing a French soldier was apparently motivated by his religious beliefs, in an eerie echo of an attack last week in London, in which a British serviceman was killed.

Pvt. Cedric Cordiez, 25, was approached from the back and stabbed in the neck at a shopping mall in a suburb of Paris on Saturday. He was treated at a military hospital and released on Monday, officials said.

If Snigdha Nandipati, the 14-year-old who won last year's Scripps National Spelling Bee, had been asked to define her winning word, "guetapens," things might have turned out differently.

This year, a vocabulary test with word definitions is, for the first time in the bee's 86-year history, part of the competition. Preliminary and semifinal contestants must pass the test to get to the finals of the grueling competition.

Alan Krueger, the chairman of the President's Council of Economic Advisers, says he will step down to return to Princeton to resume his post as a professor of economics.

Krueger, who has served as CEA chairman for the past two years, will return to Princeton in time for the beginning of the fall term. The Associated Press quotes a source familiar with the situation as saying Jason Furman, who served in President Obama's 2008 campaign, will be tapped as a replacement.
