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!":


Dallas Deploys Old Weapon In New Mosquito Fight

Aug 19, 2012

The recent outbreak of West Nile virus in the Dallas area has led to a new round of large-scale spraying for mosquitoes — a method of treating outbreaks that has generations of success, and even nostalgia, behind it.

Although the overall mosquito-killing strategy has changed little since the days when it was pioneered during construction of the Panama Canal a century ago, the chemicals used have become much safer for everything and everyone involved, save the mosquitoes, experts say.

Still, raining insecticides down from the sky has alarmed some residents of Dallas, where an outbreak of mosquito-borne West Nile has killed at least 10 people and sickened more than 200 others. On Wednesday, Dallas Mayor Mike Rawlings approved the first aerial spraying over the city in some 45 years.

The last time Dallas was the target of an "aerial application" of insecticide, malathion was used. The chemical was the subject of controversy in the 1980s when it was used to kill the Mediterranean fruit fly in California. It is considered generally safe for humans.

'The DDT Truck'

Another common method of spreading insecticide is to use a truck-based fogging apparatus. If you're in your 40s or older, you might remember running through billowing white clouds of insecticide as the mosquito-control truck swung through your neighborhood on a sticky summer evening as a child. For some reason, many remember it as "the DDT truck," assuming that the chief weapon in the fog of war against the annual mosquito onslaught was the chemical banned in 1972 over environmental concerns.

Not so, says Roger Nasci, who is chief of arboviral diseases at the Centers for Disease Control and Prevention in Atlanta. DDT was a larval control put into the water. But the fogging trucks "were generally releasing malathion or an organophosphate," he says.

In fact, those puffy white clouds we remember were mostly a thermal oil used as a carrier for the actual insecticide, he says.

Even though it was malathion and not DDT that was sprayed from those fogging trucks or over Dallas in 1966, "if you go back historically, the bad characteristics of DDT certainly flavors the public's response to insecticides," Nasci says.

A lot has changed since then.

The pesticide being deployed in Dallas is a synthetic pyrethroid, an extract from dried chrysanthemum flowers. "Nothing's perfectly safe, but there are no detectable adverse effects," he says.

With new pressure application technology, unlike in the past, very little of the agent is needed to cover a large area. Still, Nasci says people in Dallas are justified in asking questions and getting answers on aerial spraying.

"I think some of the current public concern about the aerial application of the insecticides that are being used for mosquito control in that area comes from the fact that it's not something that has been done there frequently," Nasci says.

Some 250 miles south in Houston, however, it's a different story. It's there that Kristy Murray, an associate professor of pediatrics at Baylor College of Medicine's School of Tropical Medicine, has been studying West Nile for the past decade.

"Here in the Houston area, we have one of the most sophisticated mosquito-control districts in the entire country," she says. "And we've only had 14 cases of West Nile, yet something like 25 percent of our mosquitoes are testing positive for the virus."

Local officials have been extremely aggressive with both aerial and ground spraying.

Multiple Weapons

Murray and Nasci point out that the use of chemical pesticides is only one prong of a multilayer attack on mosquitoes, targeted at either killing larval mosquitoes or adults. Getting rid of standing water, where mosquitoes breed, is important also, as are "personal measures," such as covering up and using skin-applied repellants.

And, it's important to remember that different types of mosquitoes carry different kinds of diseases. Dengue fever, for example, is carried by the Aedes mosquito, while malaria is transmitted by the Anopheles mosquito. West Nile is blamed on the common house mosquito, which is most active at night.

"That's why spraying is done at night. If you sprayed during the day, you'd miss your target," Murray says.

Although only a relatively small percentage of people get the most dangerous form of the disease, "it can cause debilitating lifelong changes in them," she says. "I think it's very important to prevent disease however we can."
