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!":


Doctors Take Aim At Epidemic Kidney Stones With Lasers

The nation is in the midst of a kidney stone epidemic.

New research shows 1 in 10 American men and 1 in 14 women has had one. And prevalence of kidney stones has shot up in recent years.

Experts had thought the disorder was increasing, but a study published this summer still surprised many by the steepness of the curve. "I'm not sure that people expected a near-doubling of kidney stones in the United States over the past 15 years," says Charles Scales, a urology researcher at University of California, Los Angeles, who led the study.

Since kidney stones aren't fatal, the problem doesn't get much attention. But they're no joke.

"I've had female patients tell me that the pain is actually worse than delivering a child without anesthesia," Scales says.

"Oh, the pain was so much that you'd be nauseous," says Henry Owens, a 69-year-old retired lawyer from Cape Cod, Mass., who suffered a kidney stone attack last month. "The pain was excruciating."

A CT scan revealed Owens had three kidney stones, two of which were blocking one of his ureters — the two tubes that carry urine from the kidney to the bladder. The third and largest was still in his kidney.

A doctor installed a tube called a stent that allows urine to bypass the stone. That was just a pain-relieving stopgap. Later, urologist Dianne Sacco performed a procedure called ureteroscopy to smash Owens' kidney stones with a laser.

Owens and Sacco allowed this reporter to watch the procedure at Massachusetts General Hospital.

With Owens under general anesthesia, Sacco passes a thin tube through his urinary passage into his bladder. A flexible fiber-optic cable gives her a sharp picture on a screen above the operating table.

On the screen the stone is egg-yolk yellow and knobby-looking. "Laser ready," she orders. Suddenly there's a quick succession of beeps as the laser fires bursts of energy at the kidney stone. On the screen there's a blizzard of tiny particles, as the laser breaks up the stone.

Lasers are becoming the treatment-of-choice for kidney stones in academic medical centers like the Mass General. Another alternative is so-called shock-wave lithotripsy, in which a machine uses high-energy sound waves to smash stones. The advantage is that it's noninvasive, that is, it doesn't require putting any equipment into the body.

Sacco says she likes the precision of laser scopes. "I can see what I'm doing; I can tell how big my fragments are," she says. And there's a better chance of rendering patients stone-free with a single treatment.

But Owens has about a 50 percent chance of developing another kidney stone. To better those odds, Sacco will send his stone fragments to a lab and analyze a 24-hour sample of his urine. That will tell her just what dietary changes Owens needs to make and whether he'll need to take medicine to avoid another painful stone.

Sacco says one probable reason for Owens' kidney stones is that he has type II diabetes. Another is that he was obese before he lost 50 pounds.

"It all goes together," she says. "The overweight problem leads to the diabetes. I think that's definitely one of the reasons why we're seeing so many more patients with stones."

Scales, the UCLA researcher, says that's what his new study found. "It's the first nationally representative sample that was able to show that linkage," he says.

As good as medicine has gotten at treating kidney stones, Scales says, the magnitude of the problem requires a new focus on preventing them.

"Kidney stones are composed of minerals the body doesn't need," Scales says. "The reason a kidney stone forms is that there is essentially too much of these minerals in the urine."

For instance, most kidney stones contain calcium. But the reason, Scales says, is not primarily an issue of too much calcium in the diet; it's too much sodium, as in salt.

That's because cells in the kidney use a chemical pump to get rid of excess sodium. The same mechanism also deals with calcium. "The key concept is that the excess sodium drives the kidneys to put out more calcium," Scales explains, and that leads to the formation of stones.

Doctors used to advise kidney stone patients to eat less calcium, but not anymore. Too little calcium can actually increase the risk of kidney stones because one of calcium's jobs is to bind a chemical called oxalate found in spinach, nuts and other foods. Too little calcium leads to too much oxalate, another frequent component of stones.

The best dietary advice, Scales says, is to drink lots of fluids. Beyond that, he says to lay off salt-rich processed foods, cut down on meat and other animal protein, and generally take in fewer calories.

For those who are at high risk — those who've already had a stone, for instance — doctors might also recommend a medicine such as potassium citrate, if people have low levels of dietary citrate in their urine. Citrate, which is found in lemons and limes, can protect against kidney stones.

And now, we turn to something else related to your diet - those kidney stones. More Americans are getting them than ever before. And it's not joke. Doctors and patients say it's one of the worst kinds of pain. NPR's Richard Knox explains how kidney stones are treated these days and what you can do to prevent them.

RICHARD KNOX, BYLINE: Henry Owens is lying on an operating room table in Boston.

UNIDENTIFIED WOMAN: All right, Mr. Owens. We're going to take good care of you. OK?

HENRY OWENS: Thank you.

KNOX: Owens, who's 69, has Type II diabetes. He's conscientious about his health. But he's about to undergo kidney stone surgery.

DR. MARK MCKEEN: All right. The next thing we're going to do is give you an oxygen mask and have you take some big deep breaths.

OWENS: Then it's over.

KNOX: A little earlier Owens told me about his kidney stone attack.

OWENS: Two weeks ago, I had severe pain above the belt on the right side. I came into Mass General and they did a CAT scan and determined I have three stones, one of which is a half-an-inch. And I think that's big.

KNOX: He says it hurt a lot.

OWENS: Oh, the pain was so much that you'd be nauseous. And the pain was excruciating.

KNOX: A doctor installed a tube that allows urine to bypass the stone. Now urologist Dianne Sacco is going to smash his stones with a laser. She passes a thin tube through his urinary passage into his bladder. A fiber-optic cable gives a clear picture on a screen above the table.

DR. DIANNE SACCO: This is where the ureter enters into the bladder.

KNOX: Snaking the equipment up the ureter, Sacco finds her first target.

SACCO: And there's a stone. It's yellow and it's knobby-looking.

Laser on?


SACCO: Laser ready?



SACCO: You can see when the laser touches, you get that spray of dust. And that's a stone being broken up.

KNOX: Would you suspect that his diabetes is a risk factor for his stones?

SACCO: Yes. Definitely.

KNOX: Not only is diabetes a risk factor, but obesity is too. And although Owens has lost 50 pounds, a few years ago he was considered obese.

SACCO: That was one of his risk factors. And I think that's definitely one of the reasons why we're seeing so many more patients with stones.

KNOX: In fact, America is in the midst of a kidney stone epidemic.

DR. CHARLES SCALES: Clearly, the prevalence of kidney stones over the past 15 years or so has almost doubled.

KNOX: That's Dr. Charles Scales of UCLA. He led a study published this summer in the journal European Urology. It found one in 10 American men have had a kidney stone, and one in 14 women, and that being obese or diabetic raises the risk. Yet very little attention is paid to preventing this problem.

SCALES: If we treated heart disease today like we treat kidney stones, we would only treat people who are having chest pains or actual heart attack and we wouldn't think about things like smoking, cholesterol or high blood pressure.

KNOX: People can lower their risk of kidney stones by paying attention to what they eat and drink.

SCALES: You really cannot underestimate the value of drinking plenty of fluids in terms of preventing kidney stone formation.

KNOX: Beyond that, lay off salt-rich processed foods, cut down on meat and other animal protein, and generally take in fewer calories.

Most kidney stones are made of calcium. But experts don't tell people to cut their calcium intake. Because surprisingly, that can actually increase your risk.

SCALES: Too much is not good and too little is not good. You really want to be in the middle.


KNOX: In the operating room, Dr. Sacco's laser is pointed at Henry Owens' third kidney stone.

SACCO: This is the biggest stone that we'll take care of in him.

KNOX: And how big are we talking about here?

SACCO: One-point-one centimeters.

KNOX: A little bigger than a marble. Sacco shatters it into tiny pieces. She removes some, the rest will pass.

SACCO: That's it, we're done everybody.

KNOX: Owens has about a 50 percent chance of developing another kidney stone. To better those odds, Sacco will send his stone fragments to a lab and also analyze his urine. That will tell her just what dietary changes he needs to make and whether he'll need to take medicine to avoid another painful stone.
