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.

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.

Scientists Use Stem Cells To Create Eggs In Mice

Oct 5, 2012

Transcript

RENEE MONTAGNE, HOST:

Scientists have, for the first time, used stem cells to create eggs in mice. This long-sought breakthrough raises the possibility of some day doing the same thing to help treat infertility in people. As NPR's Rob Stein reports, that's generating a lot of debate.

ROB STEIN, BYLINE: Scientists have long known that stem cells can be transformed into virtually any kind of cell in the body. That's why there's been so much excitement about trying to use them to cure diseases. But one big goal for stem cells has long remained elusive: the ability to turn them into eggs. Now, scientists at Kyoto University in Japan say they have finally done it. In this week's issue of the journal Science, the researchers report they used stem cells to create eggs in mice. They then used those eggs to breed healthy mice.

GEORGE DALY: It's just a really remarkable accomplishment.

STEIN: George Daly is a Harvard stem cell scientist.

DALY: This work does - it really does create remarkable possibilities for the future.

STEIN: For one thing, the work raises the possibility that stem cells could be used to generate a limitless supply of eggs for any woman at any point in her life. Ronald Green is a Dartmouth bioethicist.

RONALD GREEN: It may be possible for women to live their lives in a very different way, to stop the biological clock altogether.

STEIN: Now, a lot more work needs to be done to show this could be done in humans, too. But Daly says mice are similar enough to humans to think that that's a good bet. So some experts say the work could have much more far-reaching implications. Here's Dartmouth bioethicist Ronald Green again.

GREEN: All this suggests profound culture changes that might be forthcoming.

STEIN: The same group of scientists previously showed they could make sperm the same way. Together, Stanford bioethicist Hank Greely says this could let gay men and lesbian couples have truly genetically related children for the first time.

HANK GREELY: If you've got a lesbian couple, it becomes very easy. You make eggs from one, sperm from the other, and one of two of them carries the pregnancy.

STEIN: And Greely says there are potentially many other possibilities, especially if combined with new genetic techniques that let people choose their children's traits more easily.

GREELY: I think there's a good chance that in 20 to 40 years, most kids in countries with good health care systems will not be conceived in bed or the back seat of a car, but will be conceived in a Petri dish so their parents can get that blond or that brunette that they wanted, or to get somebody that they think will have a slightly higher chance of being good at math or good at music.

STEIN: Now, a lot of this is highly speculative and may never happen. But just the possibility is deeply troubling for some people. David Prentice follows these issues for the Family Research Council.

DAVID PRENTICE: That idea cheapens all life, in a way - not just embryonic or fetal life, but babies and the rest of us when we start treating life as a manufacturing proposition.

STEIN: That kind of reaction worries many scientists. They fear the Brave New World speculation may trigger such an intense reaction that it will squelch the possible benefits. Daniel Sulmasy is a professor of medicine and bioethicist at the University of Chicago.

DANIEL SULMASY: Like any other technology, whatever we've done in humankind, whether it's discovering fire or creating the wheel, you can use these things to do lots of good, and then you can use them in immoral ways.

STEIN: So it's clear that as scientists try to apply what they've learned from mice to people, a lot of ethical, moral and legal issues will need to be addressed first.
