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!":

Scientists See Progress In Alzheimer's Despite Growing List of Drug Failures

Aug 7, 2012

Another once-promising Alzheimer's drug has just been tossed on the pharmaceutical scrap heap.

This time it's a drug called bapineuzumab. Like several previous experimental drugs, it was designed to attack the plaques that build up in the brains of people with Alzheimer's.

And like those earlier drugs, it failed.

The drug company Pfizer issued a statement yesterday saying a study of about 1,300 patients with mild-to-moderate Alzheimer's disease found that bapineuzumab didn't help. Pfizer also announced it was discontinuing all studies of the intravenous form of the drug.

The failure of bapineuzumab is the latest evidence that treating Alzheimer's may not be as simple as going after plaques in the brain.

But scientists remain confident that treatments will need to target the major component of those plaques, a protein called amyloid beta or "A-beta."

"It all begins with A-beta," Robert Vassar, an Alzheimer's researcher at Northwestern University, tells Shots. "If we could limit the production of A-beta in the brain or enhance its clearance out of the brain then I think we could really make some headway in terms of preventing Alzheimer's disease and perhaps curing it."

The question is whether it makes sense to attack the A-beta in plaques that have already formed.

Recently, some scientists have suggested that the sticky plaques actually protect the brain by trapping bits of A-beta. These scientists suspect that it's free-floating particles of A-beta that actually damage brain cells.

If that's the case, drugs would have to eliminate free floating bits of A-beta, not just the A-beta in plaques.

One way to accomplish this may be to interrupt the process that forms A-beta in the first place, researchers say.

Several drugs designed to do this are in the pipeline. And their prospects are looking bright after a study found that people with a gene mutation that reduces A-beta production were much less likely to develop Alzheimer's.

The failure of plaque-attacking drugs may also be a sign that treatments need to begin well before people begin showing symptoms of Alzheimer's.

"My opinion and the opinion of many colleagues is that once the A-Beta begins to accumulate in the brain and a person actually has memory symptoms it may actually be too late," Vassar says.

And ultimately, treating Alzheimer's may require going after A-beta in several different ways, says William Mobley, chairman of the department of neurosciences at the University of California, San Diego. That could mean finding a way to both reduce production of A-beta and remove it from the brain, he says.

"Several shots on goal may be needed," Mobley says.
