Here is a look at some of the stories that CNN plans to follow this week:
Will Shell get OK to drill in Arctic?
A decision on whether Royal Dutch Shell can perform one of the first Arctic offshore oil drilling operations in recent memory is expected to come by Wednesday.
Federal regulators are to decide whether to grant Shell its final permits. If Shell gets approval and drilling goes smoothly, the operation¬†could be a catalyst for further development there. Shell and other energy companies say they can safely drill in the region, though environmentalists generally oppose Arctic drilling, saying it could put¬†a sensitive environment, and the people who rely on it, at risk, CNNMoney reports.
Shell's ships already are in the area, and one of them made news last month when it slipped its mooring and drifted close to one of Alaska's Aleutian Islands, briefly raising concerns about a possible grounding. No grounding or pollution were reported.
Greenpeace, which has been fighting against the permits, caused a stir last month when it set up a fake Shell website to mock the company and get support for an anti-drilling petition.
Rival leaders of Iran, Saudi Arabia to discuss Syria
Leaders of Iran and Saudi Arabia - rivals who support opposite forces in the uprising in Syria - are expected to discuss Syria at the¬†Organisation of Islamic¬†Countries¬†summit in Mecca on Tuesday, according to Reuters.
Sunni-dominated Saudi Arabia, one of Shiite-led Iran's main rivals in the Persian Gulf area, supports Syria's rebels. Iran, meanwhile, is the Syrian regime's last regional ally. Iranian President Mahmoud Ahmadinejad reportedly will be in Mecca at Saudi King¬†Abdullah's invitation.
The 17-month uprising in Syria has claimed 17,000 lives, according to the United Nations, and fighting continued over the weekend. ¬†Last week, the United States announced new sanctions against Syria and its supporters, focusing on Hezbollah's support for the regime and a Syrian oil company for violating U.S. sanctions on Iran.
Report on Norway massacre expected after yearlong inquiry
As Norway awaits a verdict for the man accused of killing 77 people in a shooting and bombing spree last year, an independent commission is expected to deliver a detailed report Monday on how the massacre happened, and what might be done to guard against similar attempts.
Anders Breivik¬†has admitted carrying out the July 22, 2011, attack on a Labour Party youth camp on Utoya¬†Island that killed 69 people and a bombing targeting government workers in Oslo that killed eight.¬†Norwegian Prime Minister Jens Stoltenberg¬†is expected to speak to the media about Monday's report. Stoltenberg asked for the report last year, saying he hoped it would show ways to prevent attacks.
Breivik was put on trial earlier this year, and a verdict is expected later this month.¬†Prosecutors have asked that Breivik be acquitted on the grounds of insanity, in which case he would be held in a secure mental health unit. If he is fully acquitted on the grounds of "necessity," as urged by his defense, he could go free. If he is ruled sane and found guilty of some or all the charges, he would be sentenced to up to 21 years in prison.
Verdict expected in Russia's Pussy Riot trial
In a trial that has been a cause c√©l√®bre for entertainers and Amnesty International, the Russian punk band Pussy Riot is expected to hear a verdict Friday on charges of hooliganism for performing a song critical of Russia's president in a cathedral.
In February, the band members screamed¬†"Mother Mary please drive Putin away" inside Moscow's Christ Savior Cathedral, their faces covered in neon masks. A video of the performance, ahead of the election that returned Vladimir Putin to Russia's presidency, was posted to YouTube and became a symbol for the opposition movement, Time reported.
The performance was inspired by the women's anger about the relationship between the Russian government and the Orthodox Church, according to the band's manager.¬†The Russian Orthodox Church leader Patriarch Kyril had been widely reported as saying, just before the election, that Putin's years in power have been a miracle from God.
The charges carry a potential seven-year sentence.¬†Putin has asked the court to show leniency.
NASA to report on record-breaking galaxy cluster
NASA apparently has seen something it likes in the form of galaxies far, far away, and it's set to reveal it on Wednesday.
NASA says it will talk about "an extraordinary galaxy cluster that is smashing several important cosmic records." The agency has hinted that it was uncovered with the help of the¬†Chandra X-Ray Observatory.
Using the Chandra observatory, astronomers have scoured hundreds of distant galaxies. ¬†Last year, scientists reported they used Chandra to discover that at least 30 million black holes had formed in the early history of the universe.
