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 made disparaging comments about him in several media interviews. He tweeted late Tuesday that she "has embarrassed all" with her "very dumb" comments about the candidate. Trump ended his tweet with "Her mind is shot - resign!":

Donald Trump wrapped up his public tryout of potential vice presidential candidates in Indiana Tuesday night with Gov. Mike Pence giving the final audition.

The Indiana governor's stock as Trump's possible running mate is believed to be on the rise, with New Jersey Gov. Chris Christie and former House Speaker Newt Gingrich also atop the list. Sources tell NPR the presumptive GOP presidential nominee is close to making a decision, which he's widely expected to announce by Friday.

The unassuming hero of Jonas Karlsson's clever, Kafkaesque parable is the opposite of a malcontent. Despite scant education, a limited social life, and no prospects for success as it is usually defined, he's that rarity, a most happy fella with an amazing ability to content himself with very little. But one day, returning to his barebones flat from his dead-end, part-time job at a video store, he finds an astronomical bill from an entity called W.R.D. He assumes it's a scam. Actually, it is more sinister-- and it forces him to take a good hard look at his life and values.

Donald Trump picked a military town — Virginia Beach, Va. — to give a speech Monday on how he would go about overhauling the Department of Veterans Affairs if elected.

He blamed the Obama administration for a string of scandals at the VA during the past two years, and claimed that his rival, Hillary Clinton, has downplayed the problems and won't fix them.

Teens Fare Worst After Concussions

Feb 29, 2012

Concussions affect the thinking of teenagers more than they do that of adults or children, according to a new study. But all three age groups show lasting problems with working memory after sports concussions.

People use working memory for reading, problem solving and manipulating information. It's controlled by the prefrontal cortex at the front of the brain. And that part of the brain matures during adolescence. "It likely makes it more vulnerable", says Dave Ellemberg, a professor in the department of kinesiology at the University of Montreal who led the study.

The study, which tested the thinking of 96 people about six months on average after they sustained a concussion, found that children had deficits as great as those in adults.

"Often parents and coaches will think that a child's brain is more resilient," Ellemberg told Shots. "That's not the case. Even 6 to 8 months after the injury, we find marked deficits."

What's interesting about this study is that it tested the participants' thinking two different ways. The participants took tests of memory and thinking speed used by the National Hockey League. And they also took tests while their brain activity was measured by an electroencephalogram.

Other recent research has found that the tests used by professional sports teams and, increasingly, by college and high school teams, aren't all that good at detecting the long-term effects of concussion.

Ellemberg says that in earlier tests he did with EEGs, even if people did well on the standard neuropsychological tests after a concussion, their brains were working differently than usual in order to get the job done. This, he says, shows that "that the brain is struggling much more than it normally would to complete the tasks." The findings were published in the journal Brain Injury.

In addition to working memory, the participants' ability to sustain attention and focus was also affected six months to 1 year after the injury.
