NASA has released the first picture of Jupiter taken since the Juno spacecraft went into orbit around the planet on July 4.

The picture was taken on July 10. Juno was 2.7 million miles from Jupiter at the time. The color image shows some of the atmospheric features of the planet, including the giant red spot. You can also see three of Jupiter's moons in the picture: Io, Europa and Ganymede.

The Senate is set to approve a bill intended to change the way police and health care workers treat people struggling with opioid addictions.

My husband and I once took great pleasure in preparing meals from scratch. We made pizza dough and sauce. We baked bread. We churned ice cream.

Then we became parents.

Now there are some weeks when pre-chopped veggies and a rotisserie chicken are the only things between us and five nights of Chipotle.

Parents are busy. For some of us, figuring out how to get dinner on the table is a daily struggle. So I reached out to food experts, parents and nutritionists for help. Here is some of their (and my) best advice for making weeknight meals happen.

"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!":

Too Much Calcium Could Cause Kidney, Heart Problems, Researchers Say

When it comes to a healthy diet — especially for women, and especially after menopause — nutritionists, doctors, everybody it seems, will tell you: calcium, calcium, calcium.

Federal health officials recommend that women and men younger than 50 consume 1,000 milligrams of calcium per day. The recommendation goes up to 1,200 milligrams after age 70 for men and after menopause for women, when a major drop in estrogen causes bone loss.

So, in a culture that often considers "more" to be "better," one might ask, if 1,200 milligrams of calcium is good, is 2,000 mg of calcium better?

No, says Dr. Ethel C. Siris, director of the Toni Stabile Osteoporosis Center at Columbia University Medical Center in New York. "You need enough; you don't need extra," she says.

"Extra calcium does you no good, and there is a small risk that if you take too much you might get a kidney stone," says Dr. Siris. That's because the body can only handle 600 milligrams of calcium at once. Extra calcium can build up in the bloodstream and, when excreted through kidneys in urine, it can cause a kidney stone.

That's been known for a while. But recently, a few studies raised concern that excess calcium may also calcify coronary arteries in susceptible individuals and even precipitate heart attack.

Robert Eckel, a cardiologist and endocrinologist at the University of Colorado, is a past president of the American Heart Association. While these studies are far from conclusive, and far more research needs to be done, he says they do raise the question about whether there's potentially some danger in over-the-counter calcium supplements that go beyond our usual dietary intake of calcium.

"At this point in time, there's a bit of a signal" that should raise caution but remains highly controversial. "I don't think anyone has stepped up to say calcium supplements should be abandoned," says Eckel.

That's particularly because calcium is so critical for bone health. The best plan of action, says Siris: Eat more calcium-rich foods.

"If you're somebody who has a glass of milk with breakfast, that's 300 milligrams of calcium; a container of yogurt will give you another 200 to 300 milligrams; a couple of ounces of cheese will give you 200 to 300 milligrams," she says. For most healthy adults younger than 50, that's about all you need for bone health.

If you don't eat dairy, Siris says there are plenty of other foods that also contain calcium. These include vegetables (like broccoli, bok choy and turnip greens), oranges, figs, salmon and sardines. Cereals and soy milk often have added calcium, along with added vitamin D, which is essential to help the body absorb calcium.

So, estimate your daily intake of calcium from food, says Siris, and then calculate whether you need to take an extra supplement. You may just need 300 or 600 milligrams of calcium extra, and you may not even need that every day.
