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.

Comparing Sperm Whales To Sperm: A Swimming Contest

Oct 4, 2013
Originally published on October 4, 2013 3:40 pm

If you're a big, big whale with a gigantic tail swimming through water, nothing gets in your way, not the water, not the other fish, not nothin'. You are so much bigger than the water molecules around you, you move through the sea the way humans move through the air on a calm day — you just go. Whales, I imagine, don't think much about water.

But now, imagine yourself smaller. Much, much, much smaller. Instead of a sperm whale, let's make you, say — a human sperm, a teeny little critter with hardly any mass, and a very skinny, beating tail. All of a sudden you are much closer to the size of the water molecules around you.

Now that you're little, getting through water is a huge headache. You are wedged in among equal sized H2O thingies that slow you way, way down. A human sperm in water is like a car in an enormous traffic jam — barely able to move.

So how do the littlest things in life — sperm, bacteria, pond scum — get where they need to go? How to they find food? Cows don't sit in meadows waiting for grass to grow next to their mouths ...

No, little things are cleverer than that. Much, much cleverer, as you will see in this video, elegantly illustrated by Brad Purnell, narrated by Addison Anderson and thought up by Aatish Bhatia, here's how they do it.

I guess of all the moving strategies I've ever encountered, this one — used by a little Broadway billboard-ish critter that dazzles trills of rainbow colored light in the shallow ocean — is the craziest. It uses the same strategies Brad and Aatish describe ... but it seems to think it's a Rockette at Radio City Music Hall.

And I wrote about it here.
