Twitter has reportedly acquired BlueFin Labs, which generates social TV analytics, in a deal which is said to be the social networking giant's biggest-ever.

According to Business Insider, Twitter has closed a deal to buy BlueFin, a company that specializes in helping media companies understand how people use social media in conjunction with their TV watching.

As Business Insider wrote, "Twitter's move into social TV makes a lot of sense. It hired a Head of TV last fall and there's a strong correlation between people watching shows and tweeting about them. Just look at last night's Super Bowl. With the help of a lengthy blackout, it was the most social event to ever air."

On its Web site, BlueFin is currently advertising its report on last night's Super Bowl. "On advertising's biggest day, which commercials succeeded in driving the social conversation and which fizzled? Our detailed report analyzes social chatter for Super Bowl spots: the winners, losers...and why."

Certainly, having the inside scoop on such information would help Twitter as it attempts to become more of a media company, and as it tries to bolster its advertising revenue by working hand-in-hand with brands and with TV networks. BlueFin has aimed to become a leader in the space by offering top-tier analysis of how "brands, agencies, and TV networks can tap into viewer commentary about shows and commercials to power insights, ad sales, and media buys."

Twitter did not respond to request for comment by CNET.

What Caused the Super Bowl Blackout?

All that is known so far about the Mercedes-Benz Superdome power outage that temporarily halted last night's Super Bowl game is that a crucial piece of sensing equipment operated exactly as designed: It turned the electricity off.

But officials at the Superdome and its energy company, Entergy, said further investigation is needed to get at the root cause of the electricity abnormality that plunged half of the recently renovated stadium into darkness and forced a 34-minute delay of one of the world's most watched sporting events. (See related quiz: "What You Don't Know About Electricity.")

So while sports analysts dissect how the Baltimore Ravens held off the rallying San Francisco 49ers in the second half to secure their 34-31 victory, this year's postgame analysis will include scrutiny by teams of electrical engineers and stadium systems experts.

Despite much online speculation on the subject, it's unlikely that the scale of Beyoncé's dazzling, hologram-assisted halftime show was to blame for the outage, says James L. Kirtley Jr., professor of electrical engineering at the Massachusetts Institute of Technology.

It's possible, he said, that the cause was a simple overload, like what happens in a kitchen when a coffee pot and microwave are run at the same time. "The stadium system is, of course, a lot bigger, but fundamentally [it is] very similar" to a household circuit panel, Kirtley explained.

However, based on public statements from Entergy and the Superdome, Kirtley suspects that "some other piece of equipment failed and put a short circuit across the power circuit, causing a circuit breaker to open and disconnect power to some part of the stadium circuits."

After the stadium went dark, Entergy, which supplies electricity to 2.8 million utility customers throughout the Gulf Coast, quickly announced via its Twitter feed that its service to the stadium had not been interrupted. The problem, Entergy tweeted, was on "the customer's side." A later joint statement from Entergy and Superdome managers said the problems began when a piece of equipment designed to monitor electrical load "sensed an abnormality in the system."

"Once the issue was detected, the sensing equipment operated as designed and opened a breaker, causing power to be partially cut to the Superdome in order to isolate the issue," the statement said. "The fault-sensing equipment activated where the Superdome equipment intersects with Entergy's feed into the facility."

It is standard—in fact, usually required by law—for electrical systems to include circuit breakers that automatically shut off power to prevent wires from overheating and causing a fire. Circuit breakers can trip when there is too much load on a circuit, but a power outage also can be caused by a short circuit or other type of fault.

It's not known how much electricity the Superdome was drawing when the power outage occurred; Entergy said in response to a query that it was confidential "customer" information.

It is known that energy use from the Super Bowl was estimated in advance to be 4,600 megawatts, but that included the power for the NFL hotels and Morial Convention Center during the week of the game. Entergy had agreed in advance to donate carbon credits, or investments in carbon-capture projects, to offset the carbon emissions caused by that energy use—3.8 million pounds of carbon dioxide emissions—as part of a wide-ranging "greening" effort around the game. (See related photos: "Super Bowl Caps Banner Season in NFL Green Drive.") That's as much carbon as 359 U.S. passenger cars typically emit in a year.

Superdome officials had hoped the Super Bowl would showcase to the world the $336 million in renovations that have been made to the stadium since it sustained massive water and wind damage in 2005 due to Hurricane Katrina. Some $156 million of the cost of the renovation was paid by the U.S. Federal Emergency Management Agency. That renovation included work on the stadium's electrical and lighting system, as the Superdome now has a 26,000-LED lighting fixture on 96 concave aluminum panels that ring the building's exterior, a system supported by more than five miles of copper wiring. This system, which draws no more power than a small home, won the 2012 "Excellence in Design" award in the Architainment category from Live Design Magazine, an architecture, design, and event production publication.

LED lights, in addition to being efficient, would be capable of coming on instantly after such an outage. But they are not bright enough to illuminate a field, so they provide only accent lighting. Most stadiums rely on high-intensity gas discharge fixtures for the main lighting of the venue. Such lights take some time to power up to full brightness—a half hour is common.

After emergency generators restored power to the playing field, fans still had to cope with reduced power, with escalators and credit-card machines shut down, and walkways lighted by small banks of light. Broadcasters and NFL officials also had to scramble.

Boy Safe, Kidnapper Dead as Ala. Standoff Ends

A week-long Alabama standoff in which a retired trucker held a 5-year-old boy hostage in an underground bunker has ended with the kidnapper dead and the child safe, according to law enforcement.

"FBI Agents safely recovered the child who's been held hostage for nearly a week," FBI Special Agent Steve Richardson said at a news conference.

The agent said negotiations with the suspect Richard Lee Dykes "deteriorated" in the past 24 hours.

"Mr. Dykes was observed holding a gun. At this point the FBI agents fearing the child was in imminent danger, entered the bunker and rescued the child," Richardson said.

The boy identified only as Ethan "appears physically unharmed" and is being treated at a hospital, authorities said.

Dykes, 65, is dead, but officials have not yet provided details on how he died.

Dykes allegedly shot and killed a school bus driver last week and threatened to kill all the children on the bus before taking the boy, one of the students on the bus said.

"He said he was going to kill us, going to kill us all," Tarrica Singletary, 14, told ABC News.

Dykes had been holed up in his underground bunker near Midland City, Ala., with the abducted boy for a week as police tried to negotiate with him through a PVC pipe. Police had used the talks to send the child comfort items, including a red Hot Wheels car, coloring books, cheese crackers, potato chips and medicine.

Dykes was a decorated Vietnam vet who grew up in the area. He lived in Florida until two years ago, the AP reported, and has an adult daughter, but the two lost touch years ago, neighbor Michael Creel said. When he returned to Alabama, neighbors say he once beat a dog with a lead pipe and had threatened to shoot children who set foot on his property.

Bug protects itself by turning its environment to gold

Mythical King Midas was ultimately doomed because everything he touched turned to gold. Now, the reverse has been found in bacteria that owe their survival to a natural Midas touch.

Delftia acidovorans lives in sticky biofilms that form on top of gold deposits, but exposure to dissolved gold ions can kill it. That's because although metallic gold is unreactive, the ions are toxic.

To protect itself, the bacterium has evolved a chemical that detoxifies gold ions by turning them into harmless gold nanoparticles. These accumulate safely outside the bacterial cells.

"This could have potential for gold extraction," says Nathan Magarvey of McMaster University in Hamilton, Ontario, who led the team that uncovered the bugs' protective trick. "You could use the bug, or the molecules they secrete."

He says the discovery could be used to dissolve gold out of water carrying it, or to design sensors that would identify gold-rich streams and rivers.

The protective chemical is a protein dubbed delftibactin A. The bugs secrete it into the surroundings when they sense gold ions, and it chemically changes the ions into particles of gold 25 to 50 nanometres across. The particles accumulate wherever the bugs grow, creating patches of gold.

Deep purple gold

But don't go scanning streams for golden shimmers: the nanoparticle patches do not reflect light in the same way as bigger chunks of the metal – giving them a deep purple colour.

When Magarvey deliberately snipped out the gene that makes delftibactin A, the bacteria died or struggled to survive exposure to gold chloride. Adding the protein to the petri dish rescued them.

The bacterium Magarvey investigated is one of two species that thrive on gold, both identified a decade or so ago by Frank Reith of the University of Adelaide in Australia. In 2009 Reith discovered that the other species, Cupriavidus metallidurans, survives using the slightly riskier strategy of changing gold ions into gold inside its cells.

"If delftibactin is selective for gold, it might be useful for gold recovery or as a biosensor," says Reith. "But how much dissolved gold is out there is difficult to say."

Scotland Yard stole dead children's identities: report

LONDON: London's Metropolitan Police stole the identities of some 80 dead children and issued false documents in their names for use by undercover officers, Britain's Guardian newspaper reported on Sunday.

The force authorised the practice over three decades for officers attempting to infiltrate protest groups, without informing the children's parents, the broadsheet said.

Its investigation described officers creating aliases based on the dead children's details and being issued with documents such as passports and driving licences in their names.

Some officers reportedly spent up to a decade pretending to be these people.

Scotland Yard said it did not currently authorise the practice and had launched an investigation into "past arrangements".

"We appreciate the concerns that have been raised," the force said.

"We can confirm that the practice referred to in the complaint is not something that would currently be authorised."

Keith Vaz, chairman of the British parliament's home affairs committee, described the practice as "gruesome".

"It will only cause enormous distress to families who will discover what has happened concerning the identities of their dead children," he told the Guardian. "This is absolutely shocking."

One unnamed officer, who adopted the fake identity of Pete Black while operating undercover in anti-racist groups, told the newspaper he felt he was stomping on the grave" of the four-year-old boy whose identity he used.

Another argued that the practice could be justified on the grounds that it was for the "greater good".

Both officers worked for a Scotland Yard unit called the Special Demonstration Squad, which was disbanded in 2008.

The Guardian said it had seen a document indicating that around 80 officers used dead children's identities between 1968 and 1994.

Super Bowl does Wi-Fi on a massive scale

There should be no shortage of Wi-Fi at the Super Bowl. And the NFL want to make sure it stays that way.

The Wi-Fi network at the Superdome in New Orleans has been structured and reinforced to handle a stunning 30,000 simultaneous connections during the big game, starting shortly, between the San Francisco 49ers and the Baltimore Ravens. Ars Technica reported that detail and lots more about the setup -- for instance, there 700 wireless access points inside the stadium, and 250 right outside for folks in the parking lots.

Clearly, the NFL understands that we're already deep in the
tablet and smartphone era when people expect easy, uninterrupted access to Facebook, Twitter, Instagram, YouTube, and more.

But not unregulated access. Fans entering the Superdome are having their bags inspected for wireless gear that could undermine the robust functioning of the Wi-Fi network. There will be no "rogue access points," Dave Stewart, director of IT and production for Superdome management firm SMG, told Ars Technica:

Every device that enters the building has to go through a frequency scan and be authorized to enter. At the perimeter the devices are identified and tagged. If they present a potential for interference, they are remediated at that moment. Either the channel is changed or it is denied access. It's all stopped at the perimeter for this event.

One of the biggest worries is about devices such as wireless cameras tuned to the 2.4GHz frequency range.

The new Wi-Fi network was installed just this season, and though there were some trial runs during regular-seasons games, the Super Bowl marks the first time the network has been publicly advertised as available to all fans, according to Ars Technica. Verizon Wireless built the network, using Cisco gear.

Pictures We Love: Best of January

Photograph by Dieu Nalio Chery, AP

The magnitude 7 earthquake that struck near Port au Prince, Haiti, in January 2010 so devastated the country that recovery efforts are still ongoing.

Professional dancer Georges Exantus, one of the many casualties of that day, was trapped in his flattened apartment for three days, according to news reports. After friends dug him out, doctors amputated his right leg below the knee. With the help of a prosthetic leg, Exantus is able to dance again. (Read about his comeback.)

Why We Love It

"This is an intimate photo, taken in the subject's most personal space as he lies asleep and vulnerable, perhaps unaware of the photographer. The dancer's prosthetic leg lies in the foreground as an unavoidable reminder of the hardships he faced in the 2010 earthquake. This image makes me want to hear more of Georges' story."—Ben Fitch, associate photo editor

"This image uses aesthetics and the beauty of suggestion to tell a story. We are not given all the details in the image, but it is enough to make us question and wonder."—Janna Dotschkal, associate photo editor

Super Bowl XLVII Brings a First, a Last and a Triumph for NOLA

There's more than just a trophy on the line for Superbowl XLVII -- as two sibling head coaches are pitted against each other for the first time, while one of the NFL's greatest players turns in his final performance, and then there's the question on everyone's minds:

Will Beyonce lip sync during the half-time show?

20 Bizarre Items Inspired by the 2013 Superbow

More than 150,000 fans have flocked to New Orleans for the big game today between the San Francisco 49ers and the Baltimore Ravens, while it's estimated at least 100 million more will watch from home.

The game will be played in the rebranded Mercedes-Benz Superdome, the same venue that nearly eight years ago housed refugees from Hurricane Katrina in squalid conditions, becoming a symbol of the storm's fury and the human suffering that followed in its aftermath.

Today, 75,000 ticketholders will pack the stadium, marking a moment of triumph for the city.

Sibling Rivalry

No matter the outcome of the game, one thing is already for certain: Coach Harbaugh is getting a Super Bowl ring.

For the first time in professional football history, a pair of brothers are leading opposing teams at the Super Bowl.

John Harbaugh, 50, head coach of the Baltimore Ravens, will face off against younger brother Jim Harbaugh, 49, skipper of the San Francisco 49ers.

The two, with just 15 months difference in their ages, grew up in Ann Arbor, Mich., and both began their coaching careers working for their father Jack, a college coach at Western Kentucky and later at Western Michigan. The brothers are close and consider the matchup, dubbed by sportswriters as the "HarBowl" a bittersweet moment for the family, knowing one will lose.

"It's probably a little tougher emotionally," John Harbaugh said at a press conference last week. "It's a little tougher just from the sense of I don't think you think about it when you're coaching against somebody else; it's more about the scheme and the strategy. There's a little bit of a relationship element that's more strong than maybe coaching against someone else.

"I'll have a better answer for you after the game," he said. "I've never been through this before. This is all new."

Ray Lewis' Final Game

The game is expected to be the last for Ravens linebacker Ray Lewis, 37.

The former Superbowl MVP and a two-time defensive player of the year, has made headlines on and off the field during his 17-season career.

In 2000, a fight broke out after an Atlanta Super Bowl party, leaving two men dead. Lewis faced double murder charges, however in a plea agreement, the charges were dropped. Lewis pleaded guilty to obstruction of justice and was sentenced to probation. The case against his two co-defendants fell apart and the murders remain unsolved.

Most recently, Lewis was reported to have used deer antler spray and pills, a substance banned by the NFL, to help heal a torn triceps. Lewis has denied taking any illegal substances.

Hype Surrounding Beyonce, Commercials

For non-football fans, today has been dubbed the Beyonce Bowl.

The megastar lip-synced on President Obama's second inauguration, she said in a press conference on Thursday, because she didn't feel fully prepared.

Will she sing live during the half-time show tonight?

Either way, fans don't seem to mind.

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.

Tennis: Nadal shrugs off talk of return to number one

VINA DEL MAR, Chile: Rafael Nadal shrugged off talk of reclaiming the world number one spot on Saturday as the 11-time Grand Slam title winner prepared to return after a seven-month injury lay-off.

Nadal, now at five in the world after not having played since his shock second round defeat at Wimbledon in June, will be top seed at the Vina del Mar claycourt event next week.

But he is desperate to cool speculation over whether or not he will be able to return to the top of the rankings, a position currently occupied by Novak Djokovic.

"After seven months without playing, I am not even thinking of the world number one spot. I am just concentrating on doing my best," said the Spaniard.

Nadal was kept off the tour through a recurrence of his long-standing knee injury as well as illness.

Those setbacks meant he missed out on the Olympics, where he was the defending champion, the US Open, the 2012 Davis Cup final as well as last month's Australian Open.

"I am feeling good, but I need to have weeks of competition on the tour. I have to start slowly and with patience," said the seven-time French Open champion.

After playing in Chile, Nadal will head off to Brazil and Acapulco before testing his recovery to the full at the season's opening Masters events in Indian Wells and Miami.

"I don't worry now about running to be able to play the best I can. That can help me progress as far as possible," he said.

But the 26-year-old, whose ranking is at an eight-year low, warned: "I just want to be able to play at an acceptable level after such a long time."

Nadal, playing on a wild card, is top seed at the $410,000 tournament and will play doubles with Argentina's Juan Monaco on Tuesday.

In singles, he has a bye in the first round and will open his campaign at 2100GMT on Wednesday against either Argentina's Guido Pella, the world 97, or a qualifier.
