Think before you post.

That's not the message you typically get from Internet companies. The ethos on Facebook, Twitter and Instagram is to (over) share. But Nextdoor, a social network, has decided to block users from publishing certain posts, specifically when they appear to be racial profiling.

A techie tackles race

Talking about race and racial profiling does not come naturally to Nirav Tolia, the CEO of Nextdoor. And yet, he's doing it anyway.

Jean-Baptiste "Toots" Thielemans, the Belgian-American musician who cut a singular path as a jazz harmonica player, died in his sleep Monday in his hometown of Brussels. He was 94.

As expected, the Zika outbreak in Florida is growing — though how fast is still difficult to say.

State and federal health officials say mosquitoes are spreading Zika in two neighborhoods of Miami, including Miami Beach. The Centers for Disease Control and Prevention told pregnant women Friday not to go into these neighborhoods — and to consider postponing travel to all parts of Miami-Dade County.

This has been an Olympics of questions: Will everyone who goes to Rio get Zika? Can they survive the polluted water — or the polluted air? Will criminals ruin the games? Are Rio and its venues chaotic? And what is up with that green water?

Those are some of the questions I was asked by friends, colleagues and NPR's audience after I got to Rio. Several times, I gave a joking answer that was only half-joking: that the Rio Olympics are like a three-week Mentos commercial.

Millennials may be notorious for their low voter turnout, but they have growing political clout. This November, they'll rival baby boomers in terms of their sheer number of eligible voters. And that means they could be key deciders in battleground states. Theoretically, that ought to benefit a Democrat. But during the primaries, young voters were Hillary Clinton's Achilles' heel. Now Clinton is hoping they'll give her a second chance.

A former Malian rebel leader has pleaded guilty at the International Criminal Court to destroying priceless monuments in Timbuktu in 2012.

As the Two-Way has reported, the trial against Ahmad al-Faqi al-Mahdi is believed to be the first time desecration of cultural heritage has been prosecuted as a war crime by the tribunal in The Hague.

For our Newscast unit, Teri Schultz reports:

Students returned to school on Monday in Miami amid a new concern: the threat of Zika. Nine schools in Miami-Dade County are in or near a zone where nearly a month ago health officials confirmed that mosquitoes are spreading the virus.

One of them, Jose de Diego Middle School, is in Miami's Wynwood neighborhood, an area known for its restaurants, cafes and street art. It's also home to middle-class and low-income families, many newly arrived from Venezuela, Cuba and Haiti.

Former French President Nicolas Sarkozy says he's running once again for the presidency — years after a failed re-election bid that was seen as a rebuke to his leadership.

The conservative politician announced his decision to run in 2017 elections by publishing on social media an excerpt from his soon-to-be-released book. Reuters has this quote from the announcement:

"I felt I had the strength to lead this battle at a troubled time in our history. ... The five years that come will be full of danger, but also of hope."

The headline of a recent NPR's story about Omran Daqneesh, a little Syrian boy who was rescued in Aleppo, asked: "Can One Photo End A War?"

Ah, rum, with its legendary pirates bellowing for grog, tiki umbrellas peeking up from neon-colored cocktails, tequila-spiked punch at college parties. Rum, universally imbibed and yet often scorned. Most rum is "the distilled essence of industrial waste," in the words of Wayne Curtis, author of And a Bottle of Rum: A History of the New World in Ten Cocktails. That waste is molasses, the byproduct of sugar production.

In the their new book, Trump Revealed: An American Journey of Ambition, Ego, Money and Power, Michael Kranish and Marc Fisher of The Washington Post tell the story of Donald Trump's rise as a businessman, a political candidate, but above all, as a brand.

This sentence from the book captures the proliferation of the Trump brand:

When a fast-moving, erratic wildfire ignites, firefighters right away try to save homes and steer the flames away from life and property. But experts say the real danger often occurs in the hours after the big wall of flames rips through.

One of the last medals awarded at the Rio Olympics went to a 21-year-old middleweight boxer from Flint, Mich.: Claressa Shields.

It was gold. With that Sunday victory, Shields became the first U.S. boxer ever to win back-to-back gold medals.

On the podium, after the medal was slipped around her neck, she reached into her pocket, pulled out her gold medal from the 2012 London Games and draped that one over her head, too.

Editor's Note: The photos in this story may be distressing to some viewers.

Rodrigo Duterte, the new president of the Philippines, campaigned as a tough-on-crime candidate, threatening death for drug dealers.

And in the seven weeks since he took office, nearly 1,800 alleged criminals have died — at the hands of police or under mysterious circumstances. The wave of extrajudicial killings has prompted outcry from human rights watchdogs, the Catholic Church and the United Nations.
