The U.S. Supreme Court has rejected a global warming lawsuit brought by Connecticut, New York, Rhode Island, Vermont, Iowa and California against five big power companies. The case is being called the court's most important environmental ruling in years.

This Sunday, the Staatsoper and Staatskappelle will perform Ludwig van Beethoven's Symphony Nr. 5 in C minor, Op. 67 and Piano Concerto Nr. 5 in E-flat major, Op. 73. Daniel Barenboim will conduct with guest piano soloist Yuja Wang.

So, aside from free admission and a reason to leave the house on Sunday, what's the point in going to this particular performance?

Classical music concerts in Berlin...about as shocking a restaurant serving food. But in this particular case, missing the concert really would mean missing out.

Growing up in Gloucester England in the 1980s, Simon Pegg idolized American action heroes. Obsessed with Star Wars, he was the kind of kid who put a picture of Carrie Fisher/Princess Leia on his bedroom wall. In short, a nerd, who would channel his boyhood passions into a career in comedy and professional nerdom.

Former Utah Gov. Jon Huntsman formally kicks off his presidential campaign Tuesday, with New York's Statue of Liberty as a backdrop. He's hoping some tired and poor Republicans are yearning for a different kind of candidate. Huntsman holds moderate views on immigration and same-sex civil unions, and he wasn't afraid to serve in the Obama administration, as U.S. ambassador to China.

As governor, Huntsman was also a leader in a regional effort to control greenhouse gases, by capping carbon emissions and trading pollution permits.

Jim Risen, a reporter for The New York Times, will ask a court Tuesday to throw out a Justice Department subpoena. Risen says he doesn't want to testify against a CIA agent accused of leaking classified information.

Risen has a history of digging for government secrets and finding pay dirt. He helped expose the government's warrantless wiretapping program. And he ventured into the shadows again to write a history of the CIA during President George W. Bush's years.

With 2011 marking the 150th anniversary of the Civil War's beginning, tourists and history buffs are expected to travel to famous battle sites, such as Gettysburg and Bull Run, in record numbers. Missouri would like some of that attention — only Virginia and Tennessee contain more Civil War battle sites.

Missouri was on the western front of the Civil War. The Battle of Wilson's Creek was fought there; in total, more than 1,000 skirmishes and battles took place in the state.

The American public is less likely to believe in global warming than it was just five years ago. Yet, paradoxically, scientists are more confident than ever that climate change is real and caused largely by human activities.

Something a bit strange is happening with public opinion and climate change.

The organization that oversees Web addresses, the Internet Corporation for Assigned Names and Numbers, announced Monday in Singapore that it will allow nearly any word in any language to be an Internet address suffix.

There are currently 23 possible endings for a Web address — including the familiar dot-com, dot-gov, dot-edu and, of course, dot-org.

ICANN's new ruling, which may shake that up, is "the most significant change to the Internet, really, since it was created," according to Peter Dengate Thrush, chairman of ICANN's board of directors.

Climbing oil prices have led to higher airfares this summer. But not all passengers pay the same rate, says Scott Mayerowitz, airlines reporter for The Associated Press.

For a recent story, Mayerowitz and his colleague Samantha Bomkamp visited the airport and asked passengers what they had paid for their flight. "We found some incredible differences out there," he says.

Protesters in Yemen, along with key tribal and religious leaders, have spent months in the streets calling for the resignation of President Ali Abdullah Saleh and for new elections.

The Obama administration and Pentagon officials are expressing fears that al-Qaida in the Arabian Peninsula may take advantage of the current power vacuum to increase its influence. But some Yemen watchers say that while Saleh recovers in a Saudi hospital from wounds suffered during an attack on his palace, the U.S. is missing an opportunity to foster a diplomatic solution to the crisis.
