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

1 hour ago

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.

Discover the Inner Beauty of the Naked Mole Rat

Oct 25, 2013



Up next, it's time for our video pick of the week. And making his debut on SCIENCE FRIDAY is our new video producer, Luke Groskin. Hey, Luke.


FLATOW: You like this seat? Get used to it.

GROSKIN: It's nice and comfy.

FLATOW: All right. What have you got for us this week?

GROSKIN: Well, today we're going to regale ourselves in the inner beauty of the naked mole rat.


FLATOW: The inner beauty. That's almost an oxymoron. The inner beauty of the naked mole rat.

GROSKIN: Yeah. Yeah. We're going to look past their surface, which is really strange and bizarre.

Past their teeth that jut out past their lips and their hairlessness and their blindness, and we're going to look at some of their adaptations that allow them to live underground entirely.

So they are a pretty unique species. They don't come out of the underground at all. And they also have this ability to live very long. That's what makes them very special.

FLATOW: Long. By long you mean what?

GROSKIN: Like 32 years long.

FLATOW: Not dog years.


FLATOW: Thirty-two human years.

GROSKIN: Yeah. Those are naked mole rats. Those are human years. And, you know, dogs, they live about 15 years, cats maybe 20 if they're lucky. But a mouse, a creature about the size of a naked mole rat, lives only three years. So that's pretty impressive that they live 32 years. And they've developed certain molecular adaptations that allow them to reach that ripe old age of 32 years.

FLATOW: And that's why scientists are studying them.

GROSKIN: Yeah, exactly. Exactly. So there are two researchers at the University of Rochester, Dr. Vera Gorbunova and Andrei Seluanov, and what they've done is they've looked into how they live that long, how they live 32 years. And one of the main ways they do it is they don't get cancer.

FLATOW: They - the mole rats don't get cancer.

GROSKIN: That's right. There's - they don't get tumors, they don't get cancer.


GROSKIN: Yeah. It's pretty cool. And so what they did was they started by looking at the cells and they noticed right off the bat that the cells don't grow very close together. They're very claustrophobic. And then they started noticing that in the Petri dish of these cell cultures, the medium that the cells were in started getting very syrupy and gooey.

FLATOW: Slimy.

GROSKIN: Yeah. It started collecting in the vacuums that they use to clean. And, you know, they thought it was just a nuisance but it turns out - and I'm not going to give away exactly what that goo is - it turns out that goo has a lot to do with their cancer resistance. And if you want to find out what that goo was, and how they're actually resistant to cancer, you go to and you watch the video about naked mole rats.

FLATOW: Our video pick of the week. And they are very acrobatic in that video. You watch them in those little tunnels that the scientists have them in, they can turn around.

GROSKIN: Exactly. Exactly. So one of the things - that acrobaticness, that stretchiness of their skin...


GROSKIN: ...that's actually very, very tied to their cancer resistance. I'm not going to give it away but...

FLATOW: Something in the skin.

GROSKIN: Yeah. Yeah. And that elasticity, that ability to kind of stretch and go back, that has a lot to do with their cancer resistance. You know, I've actually held one and when you pick them up it kind of feels like their skin's coming off of them. They kind of hang in their skin.

FLATOW: Do they get any prettier...


GROSKIN: No. They don't. In fact, the queen - they live in these colonies called eusocial colonies, and what that means is that there's a queen and a caste system and she has two male consorts that she uses and she breeds with. But the queen, as she gets older, her spine kind of lifts up to allow more room for her babies and she gets this arched back. And she doesn't look very pretty. She's not queenly. She's not regal.

FLATOW: Well, if you want to hear - watch the secrets of the naked mole rats, go to our website. It's Great video up there, Luke.

GROSKIN: Thanks, Ira.

FLATOW: It's just terrific stuff. That's our video pick of the week. Luke Groskin, thanks for joining us.

GROSKIN: Thank you.

FLATOW: That's about all the time we have for today. Transcript provided by NPR, Copyright NPR.
