The great apes which include chimps, orangutans, gorillas and bonobos, seem to have rich emotional lives similar to our own. But just how smart are these animals? A new generation of investigators are converging on an explanation for why the non-human great apes never made the breakthrough into an accelerating human-style culture that builds on the achievements of previous generations.

This film documents the 1987 North American tour of the great rock band U2. Fresh with their success of their best selling album 'The Joshua Tree', the band plays monster gigs. Along the way, the band takes the opportunity to indulge in some special musical activities like playing with B.B. King and performing 'I Still Haven't Found What I'm Looking for' with a famous church choir. All the while, concert footage of the band's biggest hits on tour are featured while Bono speaks his mind on the problems of his homeland.

This concert film by Irish rock band U2 was shot on 25 October 2009 at the Rose Bowl in Pasadena, California, during the band's U2 360° Tour. The Rose Bowl concert featured a sold-out crowd of 97,014 people, breaking the US record for single concert attendance for one headline act. The U2 360° Tour was launched in support of the group's 2009 album No Line on the Horizon. The tour featured a 360-degree configuration, with the stage being placed closer to the center of the stadium's field than usual.

From virtually the moment we're born, there's a story that's preached across cultures and continents. It's a familiar fairy tale, that finding one true love is the key to a fulfilled and happy life. As an adult, we're forced to reconcile the messaging on monogamy with one simple fact: humans are terrible at it.
What do biology, human history and the promiscuity of bonobos reveal about monogamy? Experts and everyday couples weigh in on shifting cultural norms.

The tour was designed by Willie Williams, who has worked on every U2 tour since 1982. Williams had been toying with ideas for 360-degree stadium staging for U2 for a number of years, and presented sketches of a four-legged design to the group near the end of their Vertigo Tour in 2006. The inspiration for the 'spaceship-on-four-legs' design, nicknamed 'the Claw', came from the landmark Theme Building at Los Angeles International Airport.

The 25 October 2009 concert in Pasadena, California was streamed live on U2's YouTube channel, the first time a concert was streamed live on YouTube. Over 10 million viewers streamed the concert, making it the largest streaming event in the website's history. The shoot was directed by Tom Krueger, who had previously worked with the band on the film U2 3D.
