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.

Higgs Boson Researchers Awarded The Nobel Prize In Physics

Peter Higgs and Francois Englert have been jointly awarded the Nobel Prize in physics for their theory of how particles acquire mass, the Swedish committee announced Tuesday.

The prize was given "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider."

In 1964, Higgs of Britain and Englert of Belgium (along with a now-deceased colleague), independently proposed a particle as part of a mechanism to explain how the universe works at its most basic level. The existence of that particle, known today as the Higgs boson, or Higgs particle (and sometimes the "God particle"), was confirmed after a series of high-energy collisions at the LHC.

CERN tweets:

"The awarded theory is a central part of the Standard Model of particle physics that describes how the world is constructed," the Nobel committee said in a statement. "According to the Standard Model, every­thing, from flowers and people to stars and planets, consists of just a few building blocks: matter particles. These particles are governed by forces mediated by force particles that make sure everything works as it should. The entire Standard Model also rests on the existence of a special kind of particle: the Higgs particle."

"This particle originates from an invisible field that fills up all space. Even when the universe seems empty this field is there," the committee said. "Without it, we would not exist, because it is from contact with the field that particles acquire mass. The theory proposed by Englert and Higgs describes this process."

Higgs, 84, is with the University of Edinburgh. Englert, 80, is with the Free University of Brussels.

NPR science correspondent Geoffrey Brumfiel says that "the field is what actually does all the work in theoretical physics. The Higgs particle (or Higgs boson) is an excitation of this field."

"Higgs unifies the electromagnetic force with the weak nuclear force," Brumfiel explains. "This brings physicists a bit closer to an elusive theory of everything."
