President Obama officially took the oath of office in the Blue Room of the White House a few minutes before noon on Sunday. Chief Justice John Roberts administered the oath. Obama was sworn in using a Bible from his wife's family. After hugging various family members, he told his daughter Sasha, "I did it." The public inauguration ceremony will be held on Monday, but the Constitution states that the president must be sworn in on Jan. 20 and the inauguration ceremony is usually delayed if Jan. 20 falls on a Sunday. Vice President Joe Biden was also sworn in for a second term at his home at just after 8 o’clock this morning. Justice Sonia Sotomayor delivered his oath.

Katie Couric will have the first interview with star linebacker Manti Te’o, ABC announced Sunday. The interview will air Thursday on Katie, Couric’s new syndicated talk show. Among the many questions Couric is likely to have for Te’o, one may be just how early he revealed his hoax to the Notre Dame. According to an in-depth report in the South Bend Tribune, Te’o told the university about the scandal on Dec. 26, and a private investigation funded by the university launched early in January, and investigators searched “several sophisticated databases” for information on Lennay Kekua. The investigators, however, did not actually talk to Te’o or his family, and no one contacted Ronaiah Tuiasosopo, who Deadspin reported may be involved with the fake Twitter account. 

The death toll following the hostage crisis at an Algerian gas facility went up from 23 to 48 people Sunday, according to officials. Twenty-five additional bodies were found at the complex, all of whom were reportedly captives. Algeria’s communications minister, Mohammed Said, said that the militants came from six different countries, saying that they were “nationals of Arab and African countries and of non-African countries.” All 32 hostage takers were reportedly killed by Algerian troops.

It's all fun and games until someone gets shot. Five people were injured by accidental gunfire at three gun shows across the U.S. on Saturday. At the Dixie and Knife gun show in Raleigh, N.C., three people were wounded when a shotgun discharged at a security checkpoint. Fifty-four-year-old Emory L. Cozee accidentally shot himself while leaving the Indy 500 Gun and Knife Show in Indianapolis, even though loaded personal weapons are not allowed at the show. Finally, a man in Ohio was wounded in the arm and leg when a gun dealer was checking out a handgun he had just bought and accidentally pulled the trigger.

Hundreds of flights were canceled in Europe after a snowstorm and freezing rain swept across the continent on Sunday. Heathrow airport in London canceled hundreds of flights, while Frankfurt canceled all activity due to the weather conditions. Weather is expected to improve in some areas by tomorrow morning, but Heathrow, which is Europe's central hub, issued a statement saying, “It is possible that weather conditions at other European airports will increase the number of cancellations.”

No Bay Area, you're not dreaming. The San Francisco 49ers overcame a questionable call on a catch and beat the Atlanta Falcons 28–24 Sunday night, securing their spot in Super Bowl XLVII. It will be the 49ers’ first trip to the Super Bowl in 18 years. The team will be facing the Baltimore Ravens or New England Patriots in two weeks. If the Ravens move on, the Super Bowl would pit Jim Harbaugh against his brother, John Harbaugh, Baltimore's head coach. 

A 15-year-old boy has been arrested in connection with the shootings of five people in New Mexico. Police discovered two adults and three children dead at a home in Albuquerque on Saturday night. The boy has been charged with two counts of murder and three counts of child abuse that resulted in death. No motive or connection to the victims has been released. The bodies were found with multiple gunshot wounds, and several weapons, including an assault-type rifle, were found nearby.

NASA’s Mars rover Curiosity has found white veins of minerals in rocks, which were likely created by water flowing through fissures in the rocks. Yellowknife Bay, the area Curiosity is currently exploring, “is literally shot through with these fractures,” according to one geologist. Curiosity also found many berry-shaped spherules that scientists say are sedimentary concretions that formed in water. One expert said, “Basically these rocks were saturated with water,” adding that Yellowknife Bay represents “a jackpot unit.” Curiosity landed on Mars in August and has spent the last six months testing its instruments. It has traveled roughly a quarter of a mile since landing.

A new U.N. report claims that widespread torture and abuse of detainees continues at Afghan police and intelligence facilities. Earlier this month President Hamid Karzai said that all detainees held by the U.S. and its allies would be transferred to Afghan custody. But the new allegations of torture could make such a transfer illegal. The 100-page report, which will be released on Monday, was based on several hundred interviews and about half of the interviewed detainees and former detainees alleged torture or abuse. In 2011, a similar report caused the U.S. to halt transfers of detainees to nine Afghan facilities.

Don't be fooled by the donkey cheese—there's a reason he's the world's No.1. Novak Djokovic outlasted Stanislas Wawrinka in a grueling five-set match to advance to the quarterfinals of the Australian Open. Down a set and 1–4, Djokovic was able to rally and win 1–6, 7–5, 6–4, 6–7, 12–10. The match last five hours and ended after 2:45 a.m. in Melbourne. "I was just trying to hang in there, trying to fight," Djokovic said. Roger Federer and Andy Murray are still in the hunt for the grand slam.

Maybe he can avoid arrest this time. Megaupload founder Kim Dotcom launched a new cloud storage and file-sharing site at dawn on Sunday. Megaupload was shut down in January after police raids on Dotcom’s offices and home, amidst claims that many users were engaged in pirating content and illegally sharing it. But Dotcom says that the new site, Mega, complies with the law. “This is not some kind of finger to the U.S. government or to Hollywood,” he said. “Legally, there’s just nothing there that could be used to shut us down.” Within hours of its launch, the site had 250,000 users.

But it can’t even fly. The Batmobile that featured in the 1960s Batman TV series sold at auction for $4.2 million. The Barrett-Jackson Auction Co. in Scottsdale, Ariz., sold the 19-foot-long car to a bidder whose name has not been released. The Batmobile was actually a 1955 Lincoln Futura concept car that was transformed for the television show. A publicist said that the car’s previous owner was pleased with the auction result.

Put down your weapons and let’s talk. That’s the message Syria’s foreign minister, Walid al-Moallem, had for the country’s rebels Saturday, claiming that if they disarm and agree to take part in a national dialogue without the intervention of foreign powers, their representatives will be included in a new cabinet with wide executive powers. Al-Moallem made the plea Saturday in a live TV interview, saying, “You will be a partner in building it. Why carry arms." Also on Saturday, rebels clashed with government troops near two besieged compounds in the northeast. Earlier this month, Syrian President Bashar al-Assad dismissed calls to step down.

At least 10 al Qaeda militants were killed by a drone strike on a car in central Yemen. A witness said, “One of the strikes missed the target, and the other hit the car and left the bodies of the three people in it completely charred.” It is not clear who carried out the drone strike or who ordered it, but President Abd-Rabbu Mansour Hadi said in September that he personally approves every drone strike. Meanwhile, a bomb destroyed a house in the province of al-Bayda on Saturday night, killing 10 suspected al Qaeda operatives. Officials said the house had been used for making bombs.

St. Louis Cardinals legend Stan Musial died Saturday at age 92. He passed away in his Missouri home surrounded by his family. Musial is perhaps one of the most famous players to have played for the Cardinals, having hit about .300 17 times during his 22-year career. When he retired in 1963, he had a .331 career batting average, and was the National League's then-all-time leader in RBIs, games played, runs scored, hits, and doubles. To this day, he ranks fourth in MLB history in total hits, behind only Pete Rose, Ty Cobb, and Hank Aaron.

Pro-gun activists launched their pre-planned gun rallies at “high noon” in 49 states across the U.S. Saturday, a movement that they claim is in response to President Barack Obama’s proposals to reduce gun violence. Organized by a group called Guns Across America, the rallies are reportedly taking place at state capitals. The debate over gun control intensified in America following the Newtown massacre in which 20 children were gunned down. Vice President Joe Biden has promised executive action on gun control as soon as possible.
