Captain Sunshine wears a yellow yarmulke, yellow T-shirt and a bright-yellow cape held around his shoulders with a silky red ribbon. At a recent rally of about 200 electric-car owners in Israel, he called out questions to the crowd.

The crowd cheered yes.

When Iranians vote Friday for president, it will be an election unlike any other.

Clerics who hold supreme power in the Islamic Republic have allowed elections for decades.

But while the people vote, clerics and their allies make the rules. Those already in power choose who can run for office and limit what they do if elected.

Restrictions are tighter than ever after massive protests that followed a disputed election in 2009. In fact, the country has come to redefine the whole purpose of an election.

Nature documentaries always go on and on about how fast a cheetah can run. Cats in captivity have been clocked at 65 miles an hour, the highest speed recorded for any land animal.

And yet, scientists know very little about how the animal runs in the wild, especially when on the hunt.

"You can look at it and say, 'Oh that's fast,' " says Alan Wilson, a veterinarian at the Royal Veterinary College, London. "But you can't actually describe what route it follows, or how quickly it's gone, or the details of [the] forces it has to exert to do that."

Comedians in Cars Getting Coffee is exactly what it sounds like — a show about three things Jerry Seinfeld loves.

Once the home of the cocaine kingpin Pablo Escobar, it recorded more than 6,300 homicides in 1991, making it the world's murder capital. Then, one city government after another built schools and libraries, parks and infrastructure. The police also received an overhaul and became more adept at going after violent trafficking groups.
