Ford Motor Co. announced Monday that it has replaced President and Chief Executive Officer Mark Fields, who is retiring after nearly 30 years with the automaker.

Kids under the age of 1 should avoid fruit juice, older kids should drink it only sparingly and all children should focus, instead, on eating whole fruit, according to the American Academy of Pediatrics.

The pediatricians' group previously advised against giving fruit juice to infants under 6 months, but expanded that recommendation given evidence linking juice consumption to tooth decay and to gaining too much or too little weight.

We're going to start this hour with President Donald Trump's address to the leaders of majority Muslim nations meeting in Saudi Arabia.

In the early 1950s, Clarence White was a rookie policeman with the Indianapolis Police Department, and being African-American, there were rules he needed to follow. He says the department had a gentleman's agreement where black cops could not arrest white people.

White is the patriarch of three generations of African-American police officers in the Indianapolis Police Department. It was a career he initially did not want.

A large group of students walked out of the University of Notre Dame's commencement ceremony Sunday in protest of Vice President Mike Pence's policies.

Video from the event shows people applauding followed by loud boos as the vice president began a commencement address at the school, while dozens of students began to file out from the floor of the stadium.

The walkout was planned in protest at what organizers called Pence's policies that "have marginalized our vulnerable sisters and brothers for their religion, skin color, or sexual orientation."

The fight against terrorism is a "battle between good and evil," not a fight between "different faiths, different sects, or different civilizations," President Trump said Sunday in a widely-anticipated speech in Saudi Arabia.

This is Trump's first foreign trip as president, and he delivered the address to leaders of dozens of Arab and Muslim-majority nations. The Saudis said at least 37 leaders are present, NPR's Jane Arraf reported from Riyadh.

A new social network has grown quietly in recent months. It's called Gab, and its users are invited to #SpeakFreely — an appeal attractive to many members of the far right and others who feel their views are stifled by mainstream sites like Twitter and Facebook.

A special congressional election in the Atlanta suburbs won't be decided until June 20, but there's already a clear winner: local TV stations.

Republican Karen Handel and Democrat Jon Ossoff face each other in a runoff that's become a referendum on President Trump, and with a month to go, the House race is already the most expensive in U.S. history.

So far, the candidates and outside groups are on track to spend at least $30 million just on TV ads.

On a recent Sunday afternoon, dozens of volunteers crammed into a small Jon Ossoff for Congress field office in Chamblee, Ga. They were there to canvass for the 30-year-old political newcomer, but they also got a treat: a speech from Ossoff himself. He only spoke for about four minutes, but he devoted almost a minute of it to women in particular.

Education Secretary Betsy DeVos has been a passionate proponent of expanding school choice, including private school vouchers and charter schools, and she has the clear backing of President Trump. But does the research justify her enthusiasm?

Experts say one single, overarching issue bedevils their efforts to study the impact of school choice programs. That is: It's hard to disentangle the performance of a school from the selection of its students.

It took an explosion and 13 pounds of iron to usher in the modern era of neuroscience.

In 1848, a 25-year-old railroad worker named Phineas Gage was blowing up rocks to clear the way for a new rail line in Cavendish, Vt. He would drill a hole, place an explosive charge, then pack in sand using a 13-pound metal bar known as a tamping iron.

When Feld Entertainment, owners of Ringling Bros., announced it's canceling the circus after nearly 150 years, it was one of the biggest victories yet for animal welfare activists.

How the circus treats it animals — especially elephants and big cats — has long been a focus for groups like the Humane Society of the U.S and People for the Ethical Treatment of Animals. They see it as part of a larger change going on in this country — about how Americans view animals and the way we treat them.

Cloud Computing pulled a surprise win in the final strides of the 142nd run of the Preakness Stakes, shutting out any chances for a Triple Crown winner this year.

On an overcast late-spring afternoon, a group of bird lovers from the Earth Conservation Corps are in a boat on Washington, D.C.'s Anacostia River, and point out an osprey circling overhead. "This is like their summer vacation spot and where they have their young," says Bob Nixon, in the boat. "Then they spend most of their lives in the Amazon."

President Trump's choice to represent the United States at the Vatican, Callista Gingrich, has one especially prominent achievement as a Catholic: She is responsible for her husband, former House speaker Newt Gingrich, converting to Roman Catholicism in 2009.

"When Newt became a Catholic, it was one of the happiest moments of my life," she said in a 2012 interview with The New Yorker.
