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!":

Vaginal Ring Protects Monkeys From HIV-Like Infection

When it comes to contraception, women have many options. There are pills, patches, diaphragms and even a vaginal ring that slowly releases birth control hormones.

For preventing HIV, however, the options are limited. Woman can wear a female condom, or for partial protection, they can take a daily pill that was just approved by the FDA.

Now an animal study just published in Science Translational Medicine suggests that the vaginal ring holds promise as a new way for women to protect themselves against HIV.

A team of chemists have developed a small plastic ring that significantly reduces the risk of infection when monkeys are exposed to SHIV, a version of simian immunodeficiency virus that also carries HIV genes. Although the study is small— and it is unknown how the findings will translate to humans — the results raise hopes that an ongoing clinical trial with a similar ring will be successful in people, too.

To create a device to stop HIV infections, Thomas Zydowsky and his colleagues at the nonprofit Population Council replaced the hormone in the ring with an antiretroviral drug.

They had to tweak the composition of the ring so that it works with the drug, but they eventually found a design that reduces the rate of SHIV transmission in macaques monkeys from about 80 percent to 12 percent.

The researchers concede they don't know precisely how this result in monkeys relates to people. "There are no studies correlating protection in macaques with that in humans," Zydowsky tells Shots. "The success of the animal study just gives us a better feeling that the ring will work in people."

Other scientists seem confident about the method's potential. The National Institutes of Health launched a clinical trial last July with another ring that also releases an antiretroviral drug. The study is testing the device on nearly 3,500 women across Africa, and they hope to have results by early 2015.

Other trials that focused only on gels have had mixed results. Zydowsky says this may be because the gels are tough to use. They must be applied both before and after sex.

The ring, on the other hand, worked just as well in the monkeys when it was inserted 2 weeks or 24 hours before exposure to the virus. And, this seems like a big advantage to the rings. "Woman can put it in and than just forget about it," Zydowsky says.

Right now woman make up more than half of HIV-positive people in the world, and they are twice as likely to contract HIV during sex than men. So, if vaginal rings can be proved safe and effective, they could become popular options for HIV protection someday.
