Ravens Defeat 49ers in Historic, Unusual Super Bowl

The Baltimore Ravens emerged Super Bowl champions after one of the strangest and most incredible Super Bowl games in recent memory.

It's the second championship for the Ravens, who pulled out a 34-31 win over the San Francisco 49ers at the Superdome in New Orleans.

The Super Bowl is the biggest spectacle in American sports, and each year becomes the most watched television event in history. This year, Jennifer Hudson kicked things off with a touching performance of "America the Beautiful" with a choir of students from Sandy Hook Elementary School.

Alicia Keys accompanied herself on the piano for a long, jazzy rendition of the national anthem, before the coin toss which resulted in San Francisco receiving to start the first half.

Although the game looked at one point like it was going to be a completely unexpected blow-out, with the Ravens leading 28-6 at the beginning of the 3rd quarter, the 49ers got some unusual help that turned the showdown into a much more exciting battle.

About a third of the way into the 3rd quarter, right after a record-tying Ravens rushing touchdown, the power went out at the Superdome, knocking the lights and air conditioning out in the indoor stadium. The crowd of more than 71,000 strong, along with a lot of antsy players, coaches, and staff waited for 34 minutes for the power to fully come back on and the game to resume.

In a statement, the NFL said authorities were "investigating the cause of the power outage," and law enforcement sources told ABC News it was just an issue with the building.

That didn't stop many people on Twitter from jokingly blaming Beyonce, the energetic halftime performer who surprisingly reunited shortly with her former band Destiny's Child, for shutting down the power. After her performance, even her husband Jay-Z got in on it, tweeting "Lights out!!! Any questions??"

The 49ers quickly followed the long delay with a touchdown, getting themselves right back into the game. Then just a few minutes later, they found themselves in the end zone again, and it appeared the power outage had flipped the momentum towards the 49ers.

With a score of 31-29 with more than 7 minutes left in the game, San Francisco looked poised to make the biggest comeback in Super Bowl history, but the team, trying for its 6th title, wasn't able to overcome the Ravens lead.

Baltimore was able to run out the clock, and the game ended with a final score of 34-31. Purple and gold confetti fell as the Ravens rushed onto the field and celebrated -- with some colorful language from quarterback Joe Flacco audible on the live broadcast, who was caught saying, "f***ing awesome" on CBS' cameras.

The game was already historic thanks to the match-up for John and Jim Harbaugh, the first head coach brothers to ever face each other on football's biggest stage. It was also the final game for the future Hall of Fame linebacker Ray Lewis, who is, as of the conclusion of the game retired from football.

This is the fifth season in a row that the Ravens have made it to the playoffs, led by Coach John Harbaugh, and SB XLVII MVP Quarterback Joe Flacco. It's the team's first Lombardi trophy since 2000. Their victor tonight made them the only team left in the NFL to have never lost a Super Bowl in multiple appearances.

Sneaky ninja robot silently stalks its prey

MOVE over David Attenborough. A robot that moves only when it won't be seen or heard might make it easier to sneak up on animals and film them in the wild.

Defence labs have built robots that track people through cities, avoiding well-lit areas. But cities are noisy, so if a robot keeps a certain distance it's unlikely to be heard. Tracking and filming animals in the wild is tougher because they often have keen hearing and the environment is usually quieter. Matthew Dunbabin and his collaborator Ashley Tewes at the CSIRO Autonomous Systems Laboratory in Brisbane, Australia, are teaching a four-wheeled robot to move only when intermittent sounds - like bird or frog calls - will mask its movements.

In tests, the robot picked up the sounds of things like fork-lifts, cellphones and birds, and was able to predict whether they were likely to persist long enough to cover its movement. The robot can also identify its own noise, and guess how it will vary at different speeds and turning angles - calculating what this will sound like to a target up to 50 metres away.

With the help of a camera, laser scanner and the right algorithm, the robot can figure out which vantage points will provide the best cover so it can skulk in the shadows.

Former Navy SEAL is killed at Texas gun range

Chris Kyle was shot and killed along with another man Saturday at a gun range in Texas.

STORY HIGHLIGHTS

• Authorities: Kyle was one of two men killed Saturday afternoon


• During his Iraqi tour, insurgents nicknamed him "the devil"


• Kyle recounted his days as a sniper in a bestseller

(CNN) -- A former Navy SEAL who said his 150-plus sniper kills prompted Iraqi insurgents to place a bounty on his head was fatally shot at a Texas gun range, authorities said.

Chris Kyle, 38, was one of two men killed Saturday afternoon in Glen Rose, southwest of Fort Worth, the Texas Department of Public Safety said. Chad Littlefield, 35, was also shot to death.

Police arrested suspect Eddie Ray Routh, 25, after a brief pursuit and arraigned him on two counts of capital murder, according to the safety agency.

Kyle was a major advocate for war veterans and worked to ensure their needs were met.

"He was a man of incredible character, he led by example," said Jason Kos, Kyle's friend told CNN. "He always stopped to take time to talk to whoever was around him. Just incredibly humble, very funny as well."

He helped establish nonprofit Fitco Cares Foundation to enable veterans battling post-traumatic stress syndrome get access to exercise equipment..

In a statement, the foundation described Kyle as an "American hero," and pledged to carry on his mission.

Kyle served in four combat tours in Iraq, and received two Silver Stars, among other commendations.

He left the Navy in 2009, and later recounted his days as a sniper in "American Sniper," a New York Times best seller.

In the book, Kyle describes how Iraqi insurgents nicknamed him "the devil" and placed a bounty on his head.

He purports to have more than 150 sniper kills. According to the book, the Pentagon confirmed those kills, which Kyle described as a record number for any American.

During an interview with Time magazine last year, Kyle defended his decision to write the book despite the secretive nature of the SEAL world.

"It's kind of frowned on," he told the magazine. "But I'm not trying to glorify myself. I didn't want to put the number of kills I had in there. I wanted to get it out about the sacrifices military families have to make."

He said though killing did not come easy at first, he knew it meant saving a life.

"The first time, you're not even sure you can do it," he said in the interview. "But I'm not over there looking at these people as people. I'm not wondering if he has a family. I'm just trying to keep my guys safe. Every time I kill someone, he can't plant an IED. You don't think twice about it."

Before becoming a sniper, Kyle was a Texas rodeo cowboy. He started shooting as a child during hunting trips with his father.

After leaving the Navy four years ago, he founded Craft International, a military training company.

In addition to working with the SEALs, he also served with units in the Army and Marines, according to a bio on his company website.

His combat experience includes close-quarters battle, desert patrols and training foreign allies, it says.

Kyle also appeared on the NBC reality show "Stars Earn Stripes" that lets competitors take on missions that are based on actual military exercises.

Bus hits overpass in Boston, injuring more than 30

Updated February 3, 2013, 7:30 AM ET

After a visit to Harvard University, dozens in a group of high school students and their adult chaperones were injured when their charter bus hit a bridge after police say the driver failed to heed low-clearance warning signs.

One person was hospitalized with life-threatening injuries and three with serious injuries, the Boston Emergency Medical Services said. Thirty-four people were injured in all, EMS said.

The Calvary Coach bus was carrying 42 people and was heading back to the Philadelphia area when it struck an overpass on Soldier's Field Road in Boston, a major crosstown road, at around 7:30 p.m. Saturday, Massachusetts State Police said. Some passengers were trapped for more than an hour as rescue crews worked to free them.

In this photo released by the Boston Fire Department via Twitter, firemen work to remove injured passengers from a bus that hit an bridge as it traveled along Soldiers Field Road in the Allston neighborhood of Boston Saturday night, Feb. 2, 2013.

Authorities said the bus did not belong on the road, where a 10-foot height limit is in place and over-sized vehicles are not authorized. State Police said the driver, whose name was not released, "failed to heed signs" warning of the height limit and will likely be cited for an over-height violation. The investigation will determine if he faces more serious charges, state police said. The driver was not injured.

Ray Talmedge, owner of the Philadelphia-based Calvary Coach Bus company, said Saturday night that his driver was being interviewed by police. Talmedge, who said he didn't know anything about the road restrictions, said the driver also drives a school bus.

CBS Station WBZ Boston reported that the bus company has an adequate record with the Department of Transportation.

The students were part of a Destined for a Dream Foundation group, Talmedge said. Officials with the Bristol, Pa.-based group, a nonprofit that helps underprivileged youth, refused to comment on the crash when reached by phone.

The group's Facebook page said the trip to Harvard was to "visit the campus, sit with the office of cultural advancement, followed by a tour of the campus ... followed by Harvard Square (shopping, eating, site seeing...etc...) This should be a fun time for all!"

None of those injured was identified, and state police said they did not know how many of the injured were adults and how many were juveniles.

The bus suffered significant damage in the crash. The front part of the roof was pushed in while the center section bowed downward. Photos posted on the Fire Department's website showed firefighters standing on the top of the bus using boards to extract people. The last victim was freed from the bus around 9 p.m., according to the department.

The Massachusetts Bay Transportation Authority sent buses to pick up other passengers and get them out of the frigid temperatures.

Soldiers Field Road curves along the Charles River and passes by Harvard and Boston University. It is a major roadway to the Massachusetts Turnpike. Soldiers Field remained closed while crews tried to remove the bus.

Former SEAL Killed at Gun Range; Suspect Arrested

A man is under arrest in connection with the killing of two men at an Erath County, Texas, gun range, police said.

One of the victims is former Navy SEAL and "American Sniper" author Chris Kyle.

"We have lost more than we can replace. Chris was a patriot, a great father, and a true supporter of this country and its ideals. This is a tragedy for all of us. I send my deepest prayers and thoughts to his wife and two children," "American Sniper" co-author Scott McEwen said in a statement to ABC News.

ABC affiliate WFAA-TV in Dallas reported that Kyle and a neighbor of his were shot while helping a soldier who is recovering from post traumatic stress syndrome at a gun range in Glen Rose.

The suspect, identified as Eddie Routh, 25, was arrested in Lancaster, Texas, after a brief police chase, a Lancaster Police Department dispatcher told ABC News.

Routh was driving Kyle's truck at the time of his arrest and was held awaiting transfer to Texas Rangers, according to police.

Investigators told WFAA that Routh is a former Marine said to suffer from post-traumatic stress syndrome.

Kyle, 39, served four tours in Iraq and was awarded two Silver Stars, five Bronze Stars with Valor, two Navy and Marine Corps Achievement Medals, and one Navy and Marine Corps Commendation.

From 1999 to 2009, Kyle recorded more than 150 sniper kills, the most in U.S. military history.

Travis Cox, the director of FITCO Cares, the non-profit foundation Kyle established, said Kyle's wife Taya and their children "lost a dedicated father and husband" and the country has lost a "lifelong patriot and an American hero."

"Chris Kyle was a hero for his courageous efforts protecting our country as a U.S. Navy SEAL during four tours of combat. Moreover, he was a hero for his efforts stateside when he helped develop the FITCO Cares Foundation. What began as a plea for help from Chris looking for in-home fitness equipment for his brothers- and sisters-in-arms struggling with Post Traumatic Stress Disorder (PTSD) became an organization that will carry that torch proudly in his honor," Cox said in a statement.

After leaving combat duty, became chief instructor training Naval Special Warfare Sniper and Counter-Sniper teams, and he authored the Naval Special Warfare Sniper Doctrine, the first Navy SEAL sniper manual. He left the Navy in 2009.

"American Sniper," which was published last year in 2012, became a New York Times best seller.

The fatal shooting comes after week filled with gun related incidents -- a teen who participated in inaugural festivities was shot to death in Chicago, a bus driver was fatally shot and 5-year-old was taken hostage in Alabama and a Texas prosecutor was gunned outside a courthouse.

Two worms, same brains – but one eats the other

IF TWO animals have identical brain cells, how different can they really be? Extremely. Two worm species have exactly the same set of neurons, but extensive rewiring allows them to lead completely different lives.

Ralf Sommer of the Max Planck Institute for Developmental Biology in Tübingen, Germany, and colleagues compared Caenorhabditis elegans, which eats bacteria, with Pristionchus pacificus, which hunts other worms. Both have a cluster of 20 neurons to control their foregut.

Sommer found that the clusters were identical. "These species are separated by 200 to 300 million years, but have the same cells," he says. P. pacificus, however, has denser connections than C. elegans, with neural signals passing through many more cells before reaching the muscles (Cell, doi.org/kbh). This suggests that P. pacificus is performing more complex motor functions, says Detlev Arendt of the European Molecular Biology Laboratory in Heidelberg, Germany.

Arendt thinks predators were the first animals to evolve complex brains, to find and catch moving prey. He suggests their brains had flexible wiring, enabling them to swap from plant-eating to hunting.

Football: Beckham's arrival creates headache for PSG coach

PARIS: The unveiling of David Beckham as a Paris Saint-Germain player was undoubtedly a major media event and marketing ploy but what can the Englishman, now 37, actually offer on the pitch?

The fact that Beckham has signed only a five-month contract indicates that football is not the priority, especially as the French season finishes in mid-May and the player has admitted that he will need "a few weeks" before he is fully fit.

But even when he does take to the field, it will not be the Beckham of his peak.

After all, the former Manchester United and Real Madrid player left Europe for the MLS in 2007 -- although he has had two loan spells at AC Milan since then -- and last played for England in 2009.

"Physically I feel good, as if I were 21. I've not lost much pace because I never really had any," Beckham joked on Thursday.

However, some remain to be convinced.

Christian Gourcuff, the veteran coach of Ligue 1 club Lorient, told AFP he was far from thrilled at a signing which had "nothing to do with sport", pointing out that Ligue 1 makes "distinctive physical demands" on players.

"I am no MLS specialist but when I see the players who do well there, I think the level is some way below that of the leading European leagues," he said.

Reynald Denoueix, who won the French title as a coach with Nantes in 2001 and later coached Real Sociedad in Spain, is less sceptical and believes Beckham can still offer something, as long as he is in good shape physically.

"His qualities are his passing ability and the work he does for the team," he said. "It is very good for PSG but he needs to be in a physical condition that allows him to find space on the field and make himself available for a pass.

"If he does not have what it takes in terms of fitness, it will be enough of a problem for him just to get the ball.

"Just because he is 37 it doesn't mean that he can't be competitive. Others have proved that it is possible. But you need to have exceptional aptitudes."

Questions remain as to where coach Carlo Ancelotti will use Beckham and how high up the pecking order he will stand in a stellar squad.

"I don't know where he will be but, when you look at the course his career has taken in recent seasons, I think it will be very difficult for him to have much of an impact," Gourcuff assessed.

It seems highly unlikely that he will be given the chance to play on the right of midfield, where he first made his name at Manchester United.

Beckham remains a fantastic crosser and his ability to strike a dead ball will be an immense asset but he has never been great at beating his man and is unlikely to start now.

Besides, the 4-4-2 formation that Ancelotti has used, largely successfully, in the last couple of months, requires wide players of a very different profile.

Jeremy Menez, Ezequiel Lavezzi and Lucas Moura are all speed merchants who like to take on their man.

In other words, the exact opposite of the "Spice Boy."

As a result, the only remaining possibility looks like playing him in a deeper, central role, where he enjoyed success during his four-year spell at Real Madrid, and where his vision and precision passing may be most useful.

"But in that case, there is still a problem of how well he complements those around him. You need to be able to defend too," said Gourcuff, imagining the possibility of a partnership with the tireless Blaise Matuidi.

The idea of a three-man midfield in which the duties are more evenly shared is a possibility and would probably be the best solution for Beckham's ageing legs.

But Ancelotti abandoned such a formation when PSG's form dipped in November.

Another factor against Beckham is that his mooted move to Paris last year collapsed partly because Ancelotti could not guarantee him a minimum amount of playing time.

Alabama hostage standoff enters 5th day

STORY HIGHLIGHTS

• The suspect has been identified as 65-year-old Jimmy Lee Dykes


• Dykes is accused of killing a school bus driver and abducting a child


• Authorities have said there is no connection between Dykes and the boy

Midland City, Alabama (CNN) -- As an armed standoff entered its fifth day Saturday, authorities negotiated through a ventilation pipe with a man accused of barricading himself and a 5-year-old hostage in an underground bunker in southeastern Alabama.

Police have been tight-lipped about a possible motive since the hostage drama began unfolding in Midland City with the shooting of school bus driver and the abduction of the 5-year-old.

In a sign of perhaps how tense negotiations are between authorities and the suspect, officials have refused to detail what, if any, demands have been made by the suspect.

On Friday, the Dale County sheriff did confirm what neighbors have been saying and news outlets around Midland City have been reporting since the standoff began -- the suspected gunman's identity.

He is Jimmy Lee Dykes, 65, a Vietnam veteran and retired truck driver who moved to the area about five years ago.

Charles Poland was fatally shot in Alabama on Tuesday.

The sheriff's department released a photo of a gray-bearded, unsmiling Dykes and brief physical description: white male, 6 feet tall, weighing 170 pounds with brown eyes and gray hair.

Suspect Jimmy Lee Dykes, 65, is a Vietnam War veteran and retired truck driver.

This much is known, according to police and witness statements: On Tuesday at about 3:40 p.m., bus driver Charles Poland Jr. was shuttling children from school to their homes when he dropped children off and the gunman boarded the bus.

The gunman demanded that Poland, 66, hand over two children. Poland refused, blocking access to the bus's narrow aisle as at least 21 children escaped out of the back emergency door, according to police.

The gunman shot Poland four times, killing him; grabbed the boy and then barricaded the two of them inside a nearby bunker.

It's unclear whether the gunman was after a specific child on the bus. Police have said there is no connection between the suspect and the abducted boy, whose identity is being withheld.

The suspect, who police have identified as Dykes, is holed up in a bunker 4 feet underground and built at least partially out of PVC pipe, authorities have said.

A hostage negotiator has been communicating with the alleged gunman through a 60-foot-long plastic ventilation pipe in an effort to end the standoff.

Authorities believe the boy is physically unharmed.

The suspect agreed to let police send down coloring books, crayons and prescription medication that the boy needs for treatment for Asperger's syndrome and attention deficit disorder, State Rep. Steve Clouse told CNN.

Neighbors have said the bunker has electricity, and Dykes has been known to stay in it for up to eight days, said James Arrington, the police chief in nearby Pinckard.

Dykes has been described as a self-styled survivalist with "anti-government" views, according to the Southern Poverty Law Center's Hatewatch.

As negotiations continue, preparations were under way for Poland's funeral.

The late school bus driver will be memorialized Saturday night at a visitation service, followed by a funeral service Sunday at the Ozark Civic Center.

Alabama Gov. Robert Bentley praised Poland for protecting the children on his bus.

"He stood in that place, and when that man came to take two children, he said no. And he lost his life because of that ... he did his job, and I'm proud of him as the governor but I'm just proud of him as a human being," he said.

CNN's George Howell reported from Midland City and Chelsea J. Carter wrote from Atlanta. CNN's Joe Sutton, Greg Botelho and Tristan Smith contributed to this report.

Twitter: 250,000 users' data compromised in hacking attacks

#1157946: Twitter bird logo, social networking and microblogging service, graphic element on white / AP Graphics

Twitter said today that it recently detected a series of attempts to hack into user data, and that the attackers may have successfully absconded with some users' information.

In a blog post Friday afternoon, Twitter explained the situation, and the steps it has taken to fight off the hackers.

This week, we detected unusual access patterns that led to us identifying unauthorized access attempts to Twitter user data. We discovered one live attack and were able to shut it down in process moments later. However, our investigation has thus far indicated that the attackers may have had access to limited user information - usernames, email addresses, session tokens and encrypted/salted versions of passwords - for approximately 250,000 users. As a precautionary security measure, we have reset passwords and revoked session tokens for these accounts. If your account was one of them, you will have recently received (or will shortly) an email from us at the address associated with your Twitter account notifying you that you will need to create a new password. Your old password will not work when you try to log in to Twitter.

Twitter said in the post that a very small number of users were affected by the hacking, but it encouraged everyone who uses the service to ensure that they are practicing "good password hygiene, on Twitter and elsewhere on the Internet." Among its suggestions: using unique passwords of at least ten characters, including a mix of upper and lower case letters, numbers, and symbols. Based on attacks on other high-profile tech and media companies, Twitter also said it is recommending the U.S. Department of Homeland Security's recent advisory on disabling Java, among other precautions.

This attack was not the work of amateurs, and we do not believe it was an isolated incident. The attackers were extremely sophisticated, and we believe other companies and organizations have also been recently similarly attacked. For that reason we felt that it was important to publicize this attack while we still gather information, and we are helping government and federal law enforcement in their effort to find and prosecute these attackers to make the Internet safer for all users.
