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.

First Neutrino Message Sent Through Rock; Could One Travel Back In Time?

Mar 15, 2012

"Researchers from the University of Rochester and North Carolina State University have for the first time sent a message using a beam of neutrinos — nearly massless particles that travel at almost the speed of light," U of R reports.

And they pushed the message — which simply spelled out the world "Neutrino" — through "240 meters of stone" (787 feet).

That's right, as Live Science puts it: "For the first time, scientists have used neutrinos — the exotic fundamental particles that routinely pass right through Earth — to send a message through the ground."

Now, we're a long way from being able to send a note to someone on the other side of the world through the world. Or, say, to a submarine deep below the ocean. The scientists had to use the particle accelerator at the Fermi National Accelerator Laboratory in Illinois to make the beams of neutrinos.

And, "only one in 10 billion neutrinos are detected," the scientists say. According to Live Science, they had to build a detector that "contains layers of different materials, including carbon, lead and iron. As the neutrinos pass through it, occasionally a neutrino will collide head-on with the nucleus of one of these atoms, creating other particles that are visible to the detector."

But, the possibilities are intriguing. "In principle, you could have straight-line communication right through the center of the Earth, without satellites or cables," study leader Dan Stancil, an electrical engineer at North Carolina State University, told Live Science. "I can imagine there could be certain strategic situations where that could be very valuable."

Then there's this: Though it seems unlikely that scientists at the CERN particle physics lab in Switzerland did, as they once thought, push some neutrinos past the speed of light, what if that were possible? Then, as Live Science says, "that means a neutrino communications system could potentially send messages back in time."

Or did we just say that?

Our friends at the 13.7 blog make sense of this sort of stuff all the time.
