California's state treasurer has announced he is suspending major parts of the state's business relationship with Wells Fargo because of a scandal involving unauthorized customer accounts.

In a letter to Wells Fargo, John Chiang asked, "how can I continue to entrust the public's money to an organization which has shown such little regard for the legions of Californians who have placed their well-being in its care?"

Artificial intelligence is one of those tech terms that seems to inevitably conjure up images (and jokes) of computer overlords running sci-fi dystopias — or, more recently, robots taking over human jobs.

But AI is already here: It's powering your voice-activated digital personal assistants and Web searches, guiding automated features on your car and translating foreign texts, detecting your friends in photos you post on social media and filtering your spam.

A new study of violent behavior in more than 1,000 mammal species found the meerkat is the mammal most likely to be murdered by one of its own kind.

The study, led by José María Gómez of the University of Grenada in Spain and published Wednesday in the journal Nature, analyzed more than 4 million deaths among 1,024 mammal species and compared them with findings in 600 studies of violence among humans from ancient times until today.

The findings tell us two things:

It's once again time for the annual ritual of fear and loathing, also known as the performance review — at least for the companies that still do them.

Many have abandoned the old way of evaluating their employees in recent years. Last year, even General Electric — whose former CEO, Jack Welch, championed the system often known as "rank and yank" — did away with its annual review.

U.S Secretary of Defense Ash Carter said the U.S. has agreed to send an additional 600 troops to Iraq, in anticipation of the major upcoming operation to retake the Islamic State-held city of Mosul.

These additional troops "will increase the number of U.S. forces in Iraq to around 5,000," NPR's Tom Bowman told our Newscast unit. American troop levels in Iraq peaked at 170,000 in November 2007.

Curious George famously managed all sorts of escapes — from policemen, firemen, zookeepers and plenty other humans who didn't like his mischief. But many readers don't know that the husband-wife team who created the inquisitive little monkey — who is celebrating his 75th birthday this year — had the most harrowing escape of all.

Life changed as Sadiik Yusuf knew it about two years ago, when the FBI appeared at his front door in Minneapolis to tell him his son Abdullahi had been stopped at the airport, suspected of trying to board a flight that would take him to Syria to fight with ISIS.

It's believed to be a first — and it certainly came as a surprise: Ancient Roman coins have been found in the ruins of a castle in Okinawa, Japan, that dates to the 12th and 15th centuries. The copper coins were found in 2013; X-ray analysis shows that they bear an image of Constantine the Great.
