Presumptive Democratic presidential nominee Hillary Clinton was in Springfield, Ill., Wednesday where she sought to use the symbolism of a historic landmark to draw parallels to a present-day America that is in need of repairing deepening racial and cultural divides.

The Old State Capitol — where Abraham Lincoln delivered his famous "A house divided" speech in 1858 warning against the ills of slavery and where Barack Obama launched his presidential bid in 2007 — served as the backdrop for Clinton as she spoke of how "America's long struggle with race is far from finished."

Episode 711: Hooked on Heroin

When we meet the heroin dealer called Bone, he has just shot up. He has a lot to say anyway. He tells us about his career--it pretty much tracks the evolution of drug use in America these past ten years or so. He tells us about his rough past. And he tells us about how he died a week ago. He overdosed on his own supply and his friend took his body to the emergency room, then left.

New British Prime Minister Theresa May announced six members of her Cabinet Wednesday.

Amid a sweeping crackdown on dissent in Egypt, security forces have forcibly disappeared hundreds of people since the beginning of 2015, according to a new report from Amnesty International.

It's an "unprecedented spike," the group says, with an average of three or four people disappeared every day.

The Republican Party, as it prepares for its convention next week has checked off item No. 1 on its housekeeping list — drafting a party platform. The document reflects the conservative views of its authors, many of whom are party activists. So don't look for any concessions to changing views among the broader public on key social issues.

Many public figures who took to Twitter and Facebook following the murder of five police officers in Dallas have faced public blowback and, in some cases, found their employers less than forgiving about inflammatory and sometimes hateful online comments.

As Venezuela unravels — with shortages of food and medicine, as well as runaway inflation — President Nicolas Maduro is increasingly unpopular. But he's still holding onto power.

"The truth in Venezuela is there is real hunger. We are hungry," says a man who has invited me into his house in the northwestern city of Maracaibo, but doesn't want his name used for fear of reprisals by the government.

The wiry man paces angrily as he speaks. It wasn't always this way, he says, showing how loose his pants are now.

Ask a typical teenage girl about the latest slang and girl crushes and you might get answers like "spilling the tea" and Taylor Swift. But at the Girl Up Leadership Summit in Washington, D.C., the answers were "intersectional feminism" — the idea that there's no one-size-fits-all definition of feminism — and U.N. climate chief Christiana Figueres.

Deep In The Pacific, Scientists Discover Biggest Volcano On Earth

Sep 6, 2013

The world's largest volcano has until now been lurking undiscovered in the depths of the Pacific Ocean, according to a team of scientists who identified the massive object and reported their findings in the latest issue of Nature Geoscience.

The newly revealed Tamu Massif volcano — located about 1,000 miles east of Japan and 4 miles below the ocean's surface — is about the size of New Mexico. It not only outclasses previous record holder Mauna Loa in Hawaii by about 60 times, but it's in the same league as Olympus Mons on the planet Mars, the largest known volcano in the solar system.

It's "a gee-whiz moment, where we say, 'There are volcanoes here as big as any we've seen elsewhere in the solar system,' so it's sort of like discovering a new whale or something like that," William Sager, a professor in the Department of Earth and Atmospheric Sciences at the University of Houston who began researching Tamu Massif two decades ago, tells NPR's Christopher Joyce.

"If what they are saying is correct, that is truly a massive volcano," Brian Jicha, a geologist at the University of Wisconsin, says in an article published by National Geographic.

Nature.com reports that the mega-volcano has been inactive for millions of years, but "its very existence will help geophysicists to set limits on how much magma can be stored in Earth's crust and pour out onto the surface."

The 120,000-square-mile shield volcano took a few million years to take shape when it formed about 145 million years ago at the transition between the Jurassic and Cretaceous periods, according to Sager.

It's not tall, but it is extremely wide — a veritable undersea behemoth compared with land-based Mauna Loa, which measures just 2,000 square miles. Tamu Massif comes close to matching the geographic size of Olympus Mons.

The volcano is part of a larger underwater feature known as the Shatsky Rise, but only in the past few years has Sager's team been able to determine that it's a single volcano. "We knew it was a big mountain, some sort of volcanic mountain, but oceanic plateaus are very large features hidden beneath the ocean and it's very hard to study them," Sager says.

"The main thing was the imaging we were able to do a few years ago, but without sort of the ground truth provided by samples that we drilled out of this thing, we wouldn't have had nearly as compelling a result," he tells NPR.

Sager says before the discovery that Tamu Massif is a single volcano, scientists had expected that "something this big must be made up of a large number of volcanoes, two, three, four dozen, you just don't know."

"[We] really had no idea until we started to look at the seismic data that the lava flows all come from one place at the top of this thing," he says.

[Update at 3:30 p.m. ET: NPR's Joyce cautions that Sager's team has only surveyed a small part of Tamu Massif and that it will take further examination to convince the scientific community it's deserving of the "world's biggest" title.]

And if you're wondering what Tamu means, it's an acronym for Texas A&M University in College Station, Texas — that's where Sager worked before joining the University of Houston.

"I think the Aggies are very happy about this," Sager tells Joyce. "In fact, all the stories up in College Station lead with that fact. ... It's the world's biggest volcano, of course ... but the fact that it's named after the Aggies is the most important thing."
