"O Canada," the national anthem of our neighbors up north, comes in two official versions — English and French. They share a melody, but differ in meaning.

Let the record show: neither version of those lyrics contains the phrase "all lives matter."

But at the 2016 All-Star Game, the song got an unexpected edit.

At Petco Park in San Diego, one member of the Canadian singing group The Tenors — by himself, according to the other members of the group — revised the anthem.

School's out, and a lot of parents are getting through the long summer days with extra helpings of digital devices.

How should we feel about that?

Police in Baton Rouge say they have arrested three people who stole guns with the goal of killing police officers. They are still looking for a fourth suspect in the alleged plot, NPR's Greg Allen reports.

"Police say the thefts were at a Baton Rouge pawn shop early Saturday morning," Greg says. "One person was arrested at the scene. Since then, two others have been arrested and six of the eight stolen handguns have been recovered. Police are still looking for one other man."

A 13-year-old boy is among those arrested, Greg says.

After an international tribunal invalidated Beijing's claims to the South China Sea, Chinese authorities have declared in no uncertain terms that they will be ignoring the ruling.

The Philippines brought the case to the Permanent Court of Arbitration in The Hague, objecting to China's claims to maritime rights in the disputed waters. The tribunal agreed that China had no legal authority to claim the waters and was infringing on the sovereign rights of the Philippines.

Donald Trump is firing back at Supreme Court Justice Ruth Bader Ginsburg after she disparaged him in several media interviews. He tweeted late Tuesday that she "has embarrassed all" with her "very dumb political statements" about the candidate. Trump ended his tweet with "Her mind is shot - resign!":

Donald Trump wrapped up his public tryout of potential vice presidential candidates in Indiana Tuesday night with Gov. Mike Pence giving the final audition.

The Indiana governor's stock as Trump's possible running mate is believed to be on the rise, with New Jersey Gov. Chris Christie and former House Speaker Newt Gingrich also atop the list. Sources tell NPR the presumptive GOP presidential nominee is close to making a decision, which he's widely expected to announce by Friday.

The unassuming hero of Jonas Karlsson's clever, Kafkaesque parable is the opposite of a malcontent. Despite scant education, a limited social life, and no prospects for success as it is usually defined, he's that rarity, a most happy fella with an amazing ability to content himself with very little. But one day, returning to his barebones flat from his dead-end, part-time job at a video store, he finds an astronomical bill from an entity called W.R.D. He assumes it's a scam. Actually, it is more sinister-- and it forces him to take a good hard look at his life and values.

Summer Science: The Perfectly Toasted Marshmallow

Jun 12, 2012
Originally published on June 12, 2012 8:18 am

It's the epic quest of campers everywhere: How do you get the perfectly toasted marshmallow? In our inaugural installment of NPR's Summer Science series, we gave some guidance on the first key ingredient: how to build the campfire. (Later this summer, we'll attempt to answer the vexing question of how to stave off brain freeze.)

For the marshmallow-toasting tips, science correspondent Joe Palca again turned to Daniel Madryzkowski, a fire protection engineer from the National Institute of Standards and Technology.

Madryzkowski explains that there are two kinds of heat coming from the fire — the hot gases coming off the fire as flame (that's convective heat) and the radiant heat coming from the hot coals.

"You want to stay a little to the side of the flames, and also over an area where you see glowing coals," Madrzykowski says. The reason: It's hard to stay in the sweet spot of the dancing flames. "If you want to get it nice and toasted, you typically rely on radiant energy."

But even with Madryzkowski's supervision and pro tips, Joe still managed to torch his marshmallow. That led him to another crucial question: Why do they burn so well?

DAVID GREENE, HOST:

Here on MORNING EDITION we have turned our attention to the science behind summer activities. After all, the simplest questions can really lead to the most interesting scientific explanations. NPR science correspondent Joe Palca has agreed to help us sort through some of the mysteries that pop up on those long, lazy days of summer. And today, the epic quest for campers everywhere - how do you get that perfect roasted marshmallow?

JOE PALCA, BYLINE: These are really fine marshmallows, and we have until September 2012 to use them according to the package.

GREENE: That was Joe's voice, and he convinced Dan Madryzkowski from the National Institute of Standards and Technology to assist him in his scientific quest. They built a campfire and Joe took some pointers from the expert.

PALCA: And I'm going to hold it over this fire.

DAN MADRYZKOWSKI: You want to stay a little to the side of the flames, and also over an area where you see glowing coals.

PALCA: There are two kinds of heat coming off the fire.

MADRYZKOWSKI: If you're above the fire, you're in the convective flow.

PALCA: That's the hot gasses coming off the fire's flame. Though its flames are dancing all over the place, it's hard to stay in the sweet spot, and you can catch the marshmallow on fire if you're not careful.

MADRYZKOWSKI: But if you want to get it nice and toasted, you typically rely on radiant energy.

PALCA: That's heat coming off the glowing coals. Those coals give a more even, more consistent heat.

MADRYZKOWSKI: You could put it down a little lower, like probably right there.

PALCA: Wait, wait, we have disaster. It's caught fire. Dan explained why the marshmallow caught fire.

MADRYZKOWSKI: Because that marshmallow is a piece of fuel. Marshmallows are made predominately of sugar, and what's in the sugar?

PALCA: Sugar is made of carbon and hydrogen and oxygen, and as Dan Madryzkowski will tell you, carbon and hydrogen and oxygen are...

MADRYZKOWSKI: All the things that we need to make a nice piece of fuel.

PALCA: So now we understand why marshmallows can burn when you heat them over a fire. But if you manage not to torch them, they get a little brown and they puff up as you hold them over the coals. Why do they puff up? Well, there are pockets of air inside the marshmallow which is why it's so nice and squishy. As the marshmallow heats up, those pockets of air expand, and if you're a really good roaster, you get a delicate soufflé-like quality. There's a bit of summer science for you.
