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 arbitration at 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.

The season for blueberries used to be short. You'd find fresh berries in the store just during a couple of months in the middle of summer.

Now, though, it's always blueberry season somewhere. Blueberry production is booming. The berries are grown in Florida, North Carolina, New Jersey, Michigan and the Pacific Northwest — not to mention the southern hemisphere.

But in any one location, the season is still short. And this means that workers follow the blueberry harvest, never staying in one place for long.

Grass Mattress Was A Stone Age Bed And Breakfast

Dec 8, 2011

In archaeology, you get special bragging rights when you can lay claim to the oldest specimen of something.

Scientists in South Africa may now qualify for what they say is the world's oldest bed. Well, not a bed exactly, but more like a mattress made of grass.

What Lyn Wadley, an archaeologist at the University of Witswatersrand, found were mats of grass and sedge piled half an inch thick on the floor of a cavelike rock shelter in South Africa.

The oldest bedding is 77,000 years old. That's about 40,000 years older than the previous record for bedding. It was found in a place called Sibudu.

"We know that these were used by people very deliberately, because in amongst them were stone tools and little fragments of burnt bone," says Wadley. "People were having breakfast in bed."

A Stone Age bed and breakfast sounds rather cushy, but if you've ever lived in a cave, you know how hard it is to keep clean: Insects, for example, are a real problem.

So what these people did was lay leaves from a certain tree, the river wild quince, on top of the grass bedding. "Those leaves contain chemicals that repel insects," Wadley explains. Indigenous groups in Africa, in fact, still use these leaves for that purpose.

Mosquitoes would've been a problem at the rock shelter, since it's near a river. Birds roosted there, and they're full of lice. Even with the leafy insecticide, the place eventually would have gotten pretty infested. Just ask archaeologist (and occasional cave-dweller) John Shea from Stony Brook University.

"Caves are just disgusting places," he says. "We shelter up in caves when we do field work in Eritrea and Israel and Africa. These are places where you get bugs, you get rot."

What hunter-gatherers normally did when their crib got too disgusting was just abandon it and find another. But not at Sidubu. When Wadley and her team dug down into the dirt, they found layers and layers of bedding — burned bedding. Apparently, when the bedding got nasty, the residents burned it, then made more and stayed on, apparently for thousands of years at a time, in fact.

Shea says bedding this old doesn't surprise him. You don't need a Ph.D. to realize that sleeping on rock or dirt sucks the heat out of your body. "The interesting thing they've got," he says, "is they've got evidence for that medicinal plant use, that insecticide use. What that shows you is that these people are smart."

Smart enough to figure out which plants will give you a better night's sleep.

The research appears in the journal Science.
