The Western States Endurance Run is the world's oldest 100-mile race — and among its toughest. Runners begin the race in Squaw Valley, Calif., climb more than 18,000 feet and descend nearly 23,000 feet before they reach the finish line in Auburn, Calif.

Here's what that looks like:

This year's male winner was Rob Krar, 38, of Flagstaff, Ariz., who completed the course in 14:48:59. That's an incredible time. But the loudest cheers at the finish line on Sunday were reserved for 70-year-old Gunhild Swanson of Spokane Valley, Wash.

If you're worried about finishing everything on your to-do list, you'll get an extra second today to cram it all in.

The extra second is called a "leap second." At the very end of the day, the clock will read 11:59:60 Universal Time (the official time that international timekeepers use) or 7:59:60 p.m. ET.

Jonathan Kozol looks back on the events he wrote about 50 years ago, in Death at an Early Age.

In this short film by LA Johnson, he reads from Page 188:

Nothing says "I'm a new driver" more than a fire-red label stuck to your license plate for all to see. That's what happens in New Jersey to anyone with a learner's permit under age 21. But identifying these newest drivers doesn't necessarily help reduce crash rates, research finds.

New Jersey Gov. Chris Christie, whose political career has taken almost as many turns as a roulette wheel at an Atlantic City casino, is running for president.

He made the announcement Tuesday at Livingston High School, which he attended and where he was class president. Declaring "America is tired of hand-wringing and indecisiveness and weakness" in the White House, Christie said he is ready "to fight for the people of the United States of America."

Editor's Note: NPR Shanghai correspondent Frank Langfitt once drove a taxi as a summer job. He decided to do it again, this time offering free rides around Shanghai in exchange for stories about one of the world's most dynamic cities. Here's his latest installment.

The Internet is abuzz about the latest Easter egg found in Apple's Siri, as the virtual assistant gives a philosophical — and, to some, a personal — response to the question "What is zero divided by zero?"

Siri's on-screen answer is straightforward. But her more elaborate verbal reply easily surpasses the simple "Does not compute" with which robots in old sci-fi movies used to announce a bout of cognitive dissonance. For one thing, her answer invokes Cookie Monster.

Supreme Court justices have been turning heads this month with their choice of words, as well as with their landmark rulings.

June decisions have given us Justice Elena Kagan's bountiful Spider-Man allusions, Chief Justice John Roberts' exclamation of "What chumps!" and Justice Antonin Scalia's exhortation to "Ask the nearest hippie."

Everyone agrees on one thing: On the night of Aug. 18, 2006, Dwayne Buckle catcalled Patreese Johnson.

Johnson and six of her friends, all young lesbians of color, were walking down Sixth Avenue in New York City's West Village to hang out at the clubs in one of the gayest neighborhoods in America. That's when Buckle, a then-28-year-old black filmmaker, called out to Johnson, who was 19 at the time, with an obscene comment.

"Mister, I'm gay," Johnson says she told Buckle, trying to wave him off.
