NPR Politics presents the Lunchbox List: our favorite campaign news and stories curated from NPR and around the Web in digestible bites (100 words or less!). Look for it every weekday afternoon from now until the conventions.

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!":

Vaccine For Dengue Fever Shows A Glimmer Of Hope

Sep 10, 2012

It's human nature to hope for positive results after spending months or even years conducting a research study. In well-designed studies, however, scientists identify in advance the criteria for success, so their optimism won't color their conclusions when the study is completed.

It's fair to say that a study of an experimental vaccine for dengue fever just published in The Lancet was designed well. Unfortunately, the study failed to meet its primary criterion for success: significantly protecting school-age children from contracting the disease. So it's a bit hard to understand how a press release from the journal can characterize the results as a "dengue vaccine breakthrough."

Dengue fever is caused by a virus transmitted by mosquitoes. Some infections are mild, while others are severe and debilitating, and can lead to death. The World Health Organization estimates that 40 percent of the world's population is at risk for contracting the disease. There are no vaccines or particularly effective dengue treatments now, so finding a potent vaccine would be a big deal.

The study involved 4,002 schoolchildren in Thailand. The vaccine, made by Sanofi Pasteur, uses a modified form of the dengue virus that can provoke an immune response but can't cause disease. The ideal vaccine would be 100 percent effective in preventing cases of dengue. But here, the efficacy was only about 30 percent.

The good news is that the study showed that the vaccine is safe, and that it appears to work well against some strains of the dengue virus.

"This is an important first step in understanding the complexity of the immune response to a dengue vaccine and how to improve the vaccine to induce complete protection," Dr. Timothy Endy wrote in an email to Shots. Endy is a dengue researcher at Upstate Medical University in Syracuse, N.Y., who wasn't an author on this study.

Susan Watkins, a Sanofi spokeswoman, told Shots in an email that the company remains committed to developing the vaccine. Ongoing studies with 31,000 volunteers "will be important to document efficacy of the dengue vaccine candidate in a broader population and different epidemiological environments." The results are expected in 2014.

Vaccines aren't the only avenue scientists are pursuing to stop dengue fever.

Another approach is to reduce or eliminate the population of Aedes aegypti, the mosquito that transmits the dengue virus. Pesticides are one way to do that, but scientists from the British biotech company Oxitech have a different idea. They've developed a genetically modified male mosquito that carries a lethal gene. When the modified males mate with normal females, none of the offspring survive.

In a field trial conducted on Grand Cayman Island, reported today in the journal Nature Biotechnology, the Oxitec scientists say their approach was able to reduce the population of Aedes aegypti by about 80 percent.

It's a good start, but it's just a start. Now they'll have to see if that's adequate to slow the spread of dengue.
