"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.

For Summer's First Full Day: The Science Of Skin Color And Vitamin D

During a TED talk in 2009, anthropologist Nina Jablonski told her audience, "You have the evolution of the history of our species, part of it, written in your skin. Understand it, appreciate it, celebrate it. You are the products of evolution."

It's a beautiful thought, and an apt one to consider on this first full day of Vitamin D season, otherwise known as summer. To understand why there's a diversity of skin colors in the world today does connect us to our evolution and illuminates some reasons for high levels of Vitamin D deficiency in some modern populations.

The human lineage originated, and first flourished biologically and culturally, in Africa. Evolutionarily, each of us is African; the first people had darkly pigmented skin and were thus well-adapted to handle the high levels of UVR (ultraviolet radiation) in equatorial regions.

As Jablonski explains in her talk, UVR has both benefits and costs for the human body. On the plus side, when it strikes the skin it catalyzes Vitamin D, which is essential for bone and immune health; on the minus side, it can cause DNA damage and skin cancers. In ancient Africa, melanin acted as a natural sun screen to protect people from the dangers while still allowing the benefits of Vitamin D synthesis from the sun.

When people from some ancestral populations migrated north out of Africa, they encountered much less intense UVR. The previously adaptive sun screen of melanin was now a disadvantage, and thus lightly pigmented skin evolved. People with light skin in these northern regions spent enough time in the sun that, typically, their skin still synthesized adequate vitamin D, a process helped along in some areas by diets heavy in fish.

What we have nowadays is also a balance of pluses and minuses: A lovely rainbow diversity of skin colors that reflects the map of our ancestors' relatively recent geography, and an unfortunate risk of vitamin D deficiency that comes with spending the bulk of our hours indoors in artificial light.

This topic fascinates me not only as an anthropologist, but also as a person with a new diagnosis (at age 55) of osteoporosis. My Vitamin D level is 23.7, with a level of 30 considered minimal and a level of 50 much better.

All my life it's been drummed into me, sunscreen, sunscreen, sunscreen, especially because I am lightly pigmented with blue eyes. Correct in one way, that lesson may have contributed — along with too much time indoors, especially in winter — to the situation I'm in now. I'm seeking a physician's advice, and the Internet helps too, including this jam-packed-with-facts information sheet about Vitamin D and Vitamin D deficiency from the National Institutes of Health.

We naturally link summer and sun in our minds, yet we need to find ways to ensure adequate Vitamin D intake in all seasons.

At the 15th annual Vitamin D Workshop, underway right now in Houston, scientists are sharing information that may help us with that goal. One thing is clear: There's no one-size-fits-all answer regarding the efficacy of Vitamin D supplements or even sun exposure. As the "skin type, latitude, and season" section of this Vitamin D Council website shows, adequate sun exposure for Vitamin D synthesis differs greatly according to one's skin type and place of residence.

So today, to usher in summer, I'll try and time my UVR exposure to ensure the right balance for the pluses and minuses written into my evolved skin.
