Convention Countdown

The Republican National Convention is in 4 days in Cleveland.

The Democratic National Convention is in 11 days in Philadelphia.

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!":

Could Antibiotics Be A Factor In Childhood Obesity?

There's growing evidence that the bacteria in our gut influence our health, including how much we weigh. So what happens when antibiotics knock out some of the microbes that help us?

A study, published online today in the journal Nature, finds that antibiotics make young mice fatter by changing the mix of their gut bacteria.

Another report, published Tuesday in the International Journal of Obesity, suggests that these findings may have implications for people, too. Babies given antibiotics within the first 6 months of life were more likely to be overweight as toddlers than babies not exposed to the drugs, though the study couldn't prove antibiotics were the cause.

Since the 1950s, farmers have known that small amounts of antibiotics increase the weight of livestock by as much as 15 percent. But exactly how these drugs fatten up cattle, pigs and chickens is a bit mysterious.

To help figure it out, microbiologists at the New York University School of Medicine gave mice low doses of antibiotics for seven weeks after birth. The mice that got the drugs had an increase in body fat of about 2 to 4 percent. And, over time their weight went up, too.

The antibiotics killed some bacteria, while others flourished.

The drugs appeared to boost the ability of the mice's remaining gut bacteria to extract calories from food. The bacteria switched on genes involved in fat metabolism. This, in turn, appeared to prompted the animals to make and store more fat.

The end result was plumper mice with a mix of bacteria in the gut that looked like that one seen in obese animals. And that finding could shed light on what happens in humans.

In a companion study, pediatricians from NYU looked at how antibiotics may have influenced the weights of 11,500 babies born in the U.K. during the early 1990s.

Nearly 30 percent of the infants were given antibiotics within the first 6 months of life, and these children tended to be overweight or obese as toddlers when compared to babies not exposed to the drugs.

"Although the effect was small on an individual level," Dr. Leonardo Trasande, the lead pediatrician on the study, tells Shots, "we predict that that this rise in body mass would increase the overweight population in the U.S. by about 1.6 percent."

The elevated risk decreased when the children reached 7 years of age, and exposure to antibiotics later in life didn't have a significant impact on weight. In addition, the data don't show that the antibiotics cause the toddlers to be heavier. They simply demonstrate a correlation.

"Further studies are needed to confirm the trend," Dr. Martin Blaser, an infectious diseases specialist and co-author on both studies, tells Shots. Nevertheless, the results are provocative. "These two studies together suggest that there is a critical window during development when antibiotics may affect body weight," Blaser says.

Plus, if antibiotics are contributing to the obesity epidemic, it's one factor that doctors can control.

"We're not saying that children with severe infections shouldn't be treated with antibiotics," Blaser says. These findings just reinforce our need for judicious use of them.
