Five Days And Five Nights With Doctors Without Borders

"Look!" says Stefania Poggi. "They've made inflatable rafts."

Two dozen boys are splashing in a massive, muddy pool surrounded by 30-foot-tall earthen banks. They're jumping on grain sacks that they've filled with plastic bottles to make them float.

Poggi manages the Doctors Without Borders operation in the largest refugee camp in South Sudan.

The 35-year-old Italian is standing on the banks of the drainage ditch, which was bulldozed through the middle of the camp to alleviate flooding.

It's been one of those rumors, that some Silicon Valley third party was powering Hulk Hogan's invasion-of-privacy lawsuit against Gawker Media and its owner, Nick Denton, over a publication in 2012 of a sex tape.

"My own personal hunch is that it's linked to Silicon Valley," Denton told The New York Times, about the Hogan case and several new lawsuits that the same lawyer has brought against Gawker and its writers.

U.S. Secretary of State John Kerry (right), along with British Foreign Secretary Philip Hammond (left), speak to reporters in London on May 12. They tried to assure European banks they won't be penalized for conducting legitimate business with Iran. Critics say it should not be up to the U.S. to encourage investment in Iran.

Dear Hollywood, This Is How You Make A Movie With African Characters

You may have heard that Sean Penn's new Africa-set drama, The Last Face, got savaged at the Cannes Film Festival this week. Reviewers complained (and let me just note that I've not yet seen the film) that while Penn centers the story on a romance between two NGO doctors (Charlize Theron and Javier Bardem), he uses African conflict and tragedy mostly as a backdrop. A common lament was that the African characters weren't individualized — the Hollywood Reporter said they amounted to "bleeding wallpaper."

For Female Fruit Flies, Mr. Right Has The Biggest Sperm

You can't help but notice that Scott Pitnick has a big tattoo. It's a sperm with a long tail that winds down his right arm.

People sometimes stare. "And when I tell them what it is, they either are very interested or they pivot on their heel and walk away," says Pitnick, an evolutionary biologist at Syracuse University. "All eye contact ceases."

Some people just don't like talking about sperm. But not him. He's spent his career trying to unravel the mystery of giant sperm.
