A police officer is free on bond after being arrested following a rash of road-sign thefts in southeast Alabama.  Brantley Police Chief Titus Averett says officer Jeremy Ray Walker of Glenwood is on paid leave following his arrest in Pike County.  The 30-year-old Walker is charged with receiving stolen property.  Lt. Troy Johnson of the Pike County Sheriff's Office says an investigation began after someone reported that Walker was selling road signs from Crenshaw County.  Investigators contacted the county engineer and learned signs had been reported stolen from several roads.

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.

You, Too, Can Print Your Own Guitar

Though it's been around for three decades, 3-D printing has finally started to take off for manufacturing and even for regular consumers. It's being used for making airplane parts on demand and letting kids make their own toys. One designer is pushing the limits of 3-D printing by using it to make an acoustic guitar.

As a teenager, Scott Summit had a dream: He wanted to be a rock star. And, like his rock heroes, he wanted to design his own guitar — "one that had a sound that was designed by me," Summit says. "I just didn't like the idea of off-the-shelf guitar. I wanted my own guitar."

Summit's dream to be a rock star? That's over. But he finally made his own guitar.

It's gray and smooth like painted ceramic. It's got leafy engraving on the front. But what makes it really different is that it isn't wood. Summit printed it out of "very fine nylon powder." He says that when you do that, "you can create any shape you can dream up."

Summit keeps a printer in his office. It's a miniature version of the one that made the guitar. The printer has a laser arm that squirts a thick red liquid onto a flat surface.

"So it's just as though you are squirting out toothpaste from a toothpaste tube, doing it in very fine layers, and they're all solidifying as you go," Summit says. "You do it layer by layer, and eventually you get a physical, solid thing with a complex shape."

The printer that created the guitar cost $800,000. Mostly, those big printers are used to make parts for cars and airplanes. But Summit says 3-D printing an acoustic guitar seemed like a cool challenge.

"Because it has all this complexity inside and all these mechanical attributes in it that contribute to the acoustics, we just don't know what's going to happen when you do that," he says. "So in this case, the idea was to see, 'Could we actually do an acoustic guitar, and could it actually make a sound?' Not necessarily sound good, but could we make sound at all?"

In Summit's office, professional guitarist Shelly Doty gives it a spin for the first time. As she plays, Summit smiles; it does sound like an acoustic guitar. Doty says she enjoys playing it.

"It's not like anything I've ever played before," she says.

"As far as I know, this is the first of its type, and I didn't know it would play as well until 10 minutes ago. It's like, 'Wait, the reason it sounds bad isn't the guitar — it's me,' " Summit says, laughing.

Summit's office contains lamps with lattice work, chain mail, children's toys, prosthetic limbs — all made with 3-D printers. He's an industrial designer and director of technology for Bespoke Innovations, a San Francisco-based division of 3D Systems. He says he relishes the idea that if you can turn a meltable substance into powder — steel, silver, nylon, chrome — you can 3-D print with it.

"When you take the control of the design of something — in this case, a guitar — and you democratize that, you just give it out to the world and you say, 'Here you go, here are the tools, have fun, do what you want with it,' " Summit says. "That's what really excites me, is democratizing design."

In other words: If you can think it, you can print it.

ROBERT SIEGEL, HOST:

Car and airplane parts, kids' toys - those are just a few of the many things that can be made using 3-D printing. The technology has been around for three decades. But now, it's finally started to take off - both for manufacturers and for regular consumers. NPR's Laura Sydell has the story of one designer who is pushing the limits of 3-D printing, by printing out an acoustic guitar.

LAURA SYDELL, BYLINE: As a teenager, Scott Summit had a dream. He wanted to be a rock star, and like his rock heroes, he wanted to design his own guitar.

SCOTT SUMMIT: One that had a sound that was designed by me. I just didn't like the idea of off-the-shelf guitar. I wanted my own guitar.

SYDELL: Summit's dream to be a rock star? That's over. But he finally made his own acoustic guitar. So he handed it over to a professional, Shelley Doty, to give it a try.

(SOUNDBITE OF GUITAR STRUMMING)

SHELLEY DOTY: Wow, it's true. It's not like anything I've played before.

SYDELL: Or looked at. It's gray and smooth, like painted ceramic. It's got leafy engraving on the front. But what makes it really different is that it isn't wood. Scott Summit printed it.

SUMMIT: Out of powder; out of very, very fine, nylon powder. And when you do that a lot of times, you can create any shape you can dream up.

SYDELL: Scott Summit keeps a printer in his office. It's a mini version of the one that made the guitar.

(SOUNDBITE OF PRINTER)

SYDELL: The printer has a laser arm that's squirting a thick, red liquid onto a flat surface.

SUMMIT: So it's just as though you're squirting out toothpaste from a toothpaste tube, doing it in very fine layers. And they're all solidifying as you go. And you do it layer by layer and eventually, you'll get a physical, solid thing with a complex shape.

SYDELL: A little complex shape. With this printer, it has to fit into a 5-by-5-inch cube, but it only costs about $1,200. The printer that created the guitar? That one was 800,000 bucks. Mostly, those big ones are used to make parts for cars and airplanes, but Summit says 3-D printing an acoustic guitar seemed like a really cool challenge.

SUMMIT: Because it has all this complexity inside, and all these mechanical attributes in it that contribute to the acoustics; and we just don't know what's going to happen when you do that. So in this case, the idea was to see, could we actually do an acoustic guitar, and could it actually make a sound; you know, not necessarily sound good, but could we make some sound at all?

SYDELL: Shelley Doty gives it a spin.

DOTY: Responds well to jazz.

SYDELL: Summit perks up as he watches Doty play.

SUMMIT: So as far as I know, this is the first of its type. And I didn't know it can play, as well, until 10 minutes ago.

(LAUGHTER)

SUMMIT: I was like, wait - the reason it sounds bad isn't the guitar. It's me.

SYDELL: Summit's office is filled with lamps with latticework, chainmail, children's toys, prosthetic limbs - all made with 3-D printers. Summit's an industrial designer, and director of technology for 3D Systems in San Francisco. He relishes the idea that if you can turn a meltable substance into powder, steel, silver, nylon, chrome; you can 3-D print with it.

SUMMIT: When you take the control of the design of something - you know, in this case, a guitar - and you democratize that; you just give it out to the world - and you say, here you go, here's the tools, have fun, do what you want with it, impress us; show us what you're going to come up with - that's what really excites me, is democratizing design.

SYDELL: Summit says if you can think it, you can print it.
