In the 73^rd minute, off a corner kick, Spain’s Carles Puyol put a ball into Germany’s net off a header. Spain now moves on to the finals in the World Cup playing against the Netherlands. The circle of World Cup winners tends to be an exclusive club - only seven countries have ever won. But this year there will surely be a new member, as neither Spain nor the Netherland have ever taken home the world championship title before. Sunday's final will be an exciting match, and tomorrow, we’ll get reactions from Spain after their semi-final victory today.

And in other sports news, Lebron James will host an hour-long ESPN special tomorrow night where he will finally announce his team of choice. Fans from cities across the country have been waiting for this moment with bated breathe. It’s a rarity in sports for an athlete to take center stage in produced, hour-long televisded event outside the arena of an actual game. And unlike a press conference, James will have full control of the event. It’s kind of like American Idol meets basketball, without the Simon and Randy factors. We'll hear more about the media spectacle tomorrow on the show.

On the international front, Iran announced new guidelines for men’s haircuts. A government official appeared alongside hundreds of barbers and hairdressers to unveil a catalog describing what hair dos will be acceptable for men. The crackdown seems intended to police “un-Islamic” dress and fight Western influences. But at the same time, none of the men featured in the catalog are wearing long beards, a cornerstone in Islamic orthodoxy. This comes at a time when Iran is facing a cultural collission between a younger generation that is seeking greater freedoms and a religious government continuing to push Sharia law.  Azadeh Moavani, the author of Lipstick Jihad, joins the program tomorrow morning to talk about the cultural and political dynamics at play.

Anna Sale here on the dayside.

We had a great conversation this morning about the different ways oil is showing up on the Gulf Coast. Straight-talking Texas A&M professor Larry McKinney made plain how oil transforms as it moves through water, and how its threat to wildlife changes with it. Tomorrow, we'll look at new efforts to protect wildlife just making their way to the Gulf region. Migration season begins this week for many birds, and the federal government is taking action to try to divert as many as possible away from the now toxic areas of the Gulf of Mexico. They're creating landing strips out of converted farm land that can serve as alternate habitats during the fall and winter. But, it's no easy task to get migratory birds to choose a new destination and summer retreat, so it's unclear what impact this will have in saving vulnerable birds.

We're days into this East Coast heat wave here, and it's hard to fathom a time before air conditioning was piping through our homes and offices. But writer Stan Knox argues that some things have been lost along with all that comfort. Among them, steamy summer evenings when people gathered on their porches and ended up talking to one another. He's the author of a new book, "Losing Our Cool: Uncomfortable Truths About Our Air-Conditioned World."

Along with artificial breezes, we'll also be talking artificial light tomorrow. Jane Brox is the author of "Brilliant,"a new book that tells the story of how artificial light has shaped — and changed — our world. She also explores the future of light now that the incandescent bulb is on the outs. We get all the techy — and cultural — details in a conversation about how human invention can alter our worlds.
