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

9:43  p.m. ET: Replay of fourth down on a penalty. Ravens player ran into Akers. 4th and 2 for the Niners.

9:43  p.m. ET:  Akers kick no good, but there’s a flag on the field

9:41  p.m. ET: Superdome representative releases statement apologizing for the incident, and NFL statement says authorities are “investigating the cause of the power outage.”

9:40  p.m. ET: Fumble recovered by the 49ers. Momentum definitely swinging the 49ers way.

9:36  p.m. ET: It’s a one score game as Akers drills the extra point. He’s having a surprisingly good game, considering his dismal season. 28-20 Ravens.

9:34  p.m. ET: Frank Gore gets the ball into the end zone, and there’s a player down on the field. 28-19 Ravens.

9:32  p.m. ET: TOUCHDOWN 49ERS.

9:28  p.m. ET: Now it’s up to the 49ers defense to keep San Francisco in this game. Jacoby Jones carried the ball to the Ravens 17. His previous carry, intially listed at 109 yards, has been changed to 108 yards, tying the all-time record, not breaking it.

9:25  p.m. ET: First touchdown for San Francisco this game, after Kaepernick connects with Crabtree, who runs it into the end zone after an 80-yard drive. 28-13 Ravens.

9:18  p.m. ET: Kaepernick scrambles for a gain of five. For somebody who has used his legs so successfully this season, he seems really hesitant to try it in this game. 2nd and 5 49ers.

9:15  p.m. ET: Touchback – 49ers will start with the ball at their 20-yard line.

9:12  p.m. ET: Game resumes largely as it played out before the delay. Flacco immediately gets a first down with a 15 yard toss.

9:11  p.m. ET: Not a great start after the delay for the 49ers. A gain of 7, but short of a first down. Andy Lee comes out for the punt.

9:10  p.m. ET: That was a 34 minute delay. No statement from the NFL yet, but that must have been really frustrating for both teams.

9:10  p.m. ET: Apparently, part of the holdup was the electrical equipment on the 49ers side going out with the power. Play set to resume in the next minute or so.

9:08  p.m. ET: Luckily, so far there have been no disturbances reported in the crowd during this blackout delay.

9:05  p.m. ET: Obviously, how each team reacts in the first drive right after this power outage and long delay will be huge. In case you forgot, the 49ers will get the ball at the SF 40 after a Kaepernick sack. 3rd and 13 for the Niners.

9:00  p.m. ET: And there’s already a @SuperbowlLights twitter account.

8:59  p.m. ET: Law enforcement source tells ABC News the power outage is just a technical issue, nothing nefarious. Reporters at the game say they heard a boom in the stadium before the lights went out. Lights slowly coming back on, and players still on the field.

8:51  p.m. ET: Considering the score, the fact that this power outage delay may last as long as 20 minutes, and the fact that the halftime show is over, I wonder how many people are tuning out right about now.

8:51  p.m. ET: Power surge to blame, apparently.

8:48  p.m. ET: “Bring Beyonce Back” trending on Twitter now.

8:05  p.m. ET: Still, the 49ers rallied from a 17-0 deficit to make it to the Super Bowl so it’s tough to count them out just halfway through.

8:04  p.m. ET: Ravens dominating so far, and it’s not even really close. While the teams take a breather, Beyonce heads to the field for the half time show.

8:00  p.m. ET: First half ends with a Ray Lewis sack. The likely future Hall of Famer is retiring after this game. Strangely enough, his first NFL sack was of Jim Harbaugh – who is currently coaching the 49ers. Also in that game? Randy Moss, who is currently having a rough game for the 49ers.

7:59  p.m. ET: Field goal is Good. 21-6 Ravens at the half.

7:58  p.m. ET: Really looks like the big game jitters are getting to Kaepernick. Ray Lewis sack brings out Akers for a field goal attempt.

7:55  p.m. ET: Fun Fact – Kaepernick was drafted by the Chicago Cubs as a pitcher in 2009. You can see the pitcher still in him with some of these throws.

7:54  p.m. ET: 49ers back in the red zone after a few big gains. They still have two timeouts with less than one minute left in the second quarter.

7:52  p.m. ET: 15-yard penalty and automatic first down for the 49ers on a roughing the passer call.

7:48  p.m. ET: TOUCHDOWN RAVENS.

7:45  p.m. ET: No flag on what looked like offensive pass interference as Culliver breaks up a Flacco long throw, and we hit the two-minute warning.

7:44  p.m. ET: 2nd and 10 for the Ravens with 2 minutes left in the second quarter. The Ravens will be receiving the ball at the beginning of the second half.

7:41  p.m. ET: Kaepernick, who had been noted for his great decision making calls under pressure, is having a rough game so far. At 25 years old, this start is only the tenth pro start of his career.

7:36  p.m. ET: Tricky – fake field goal by the Ravens, but short of a first down.

7:31  p.m. ET: Another first down for the Ravens.

7:30  p.m. ET: Personal fouls by both teams cancel each other out. Ravens first down at 49ers 38.

7:24  p.m. ET: After that commercial about sports fans’ superstitions – here’s an interesting article about when those superstitions cross the line into OCD.

7:22  p.m. ET: Penalties and that fumble killing San Francisco so far. 14-3 Ravens. Ten touchdowns and no interceptions so far this postseason for Flacco.

6:40 p.m. ET: TOUCHDOWN BALTIMORE. Ravens take an early lead with a reception by Anquan Boldin.

6:39 p.m. ET: On 3rd and 9, same thing happens, but flag is down for defensive offsides – five yard penalty and replay of 3rd down.

6:39 p.m. ET: Given some time, Flacco throws ball beyond end zone for an incompletion on 2nd and 9.

6:38 p.m. ET: Ravens QB, Joe Flacco, known for his exceptionally strong arm, gets the ball to Torrey Jones at the SF 19.

6:37 p.m. ET: And a first down for the Ravens from SF 39.

6:36 p.m. ET: Better start for the Ravens, who pick up eight yards on their first down of the game.

6:11 p.m. ET: The Ravens players are introduced in the stadium to a raucous crowd.

6:09 p.m. ET: And another historic first tonight – the two head coaches are brothers, born just 15 months apart. John Harbaugh, 50, is in his fifth season as the Baltimore Ravens head coach, and has won playoff games in each of his previous seasons. Jim Harbaugh, 49, is in his second season as head coach of the San Francisco 49ers, leading his team to the playoffs both seasons.

6:05 p.m. ET: The San Francisco 49ers are going for their 6th Lombardi trophy, which would tie them for the most championships ever with the Pittsburgh Steelers. The Baltimore Ravens are trying for their second Super Bowl victory. Neither team has ever lost a Super Bowl game – and at the end of the night, there will only be one team left in the NFL to have never lost a Super Bowl game.

6:00 p.m. ET: It’s here – the biggest spectacle in American sports, the Super Bowl. We’ll be covering the game, performances and, of course, the commercials right here.

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.

Three injured as plane veers off Rome runway

ROME: A Romanian plane carrying 50 passengers veered off the runway while landing at Rome's Fiumicino airport on Saturday, injuring three people who were rushed to hospital, authorities said.

The ATR 72 turboprop plane of the Romanian airline Carpatair arriving from Pisa finished up at an angle on grass with its landing gear damaged, emergency services and airport officials said.

One of the three people hospitalised, a Romanian flight crew member, was said to have suffered spinal injuries but his condition was not life-threatening.

Another of those hurt had pelvic injuries.

Investigators were attempting to establish the cause of the accident, with bad weather -- winds and rain may have made the landing difficult -- or pilot error suspected.

A passenger on the plane told Ansa that the plane had touched down twice. "The second time the landing gear was bent out of shape and we ended up off the runway."

He described scenes of panic and screaming.

The Rome airport remained open though one of its runways was closed.

According to Italian media, several recent incidents have shed an unfavourable light on the partnership between Alitalia and Carpatair.

The Carpatair plane involved in Saturday's accident was carrying out an Alitalia flight.

In a statement Alitalia said that "strong winds" had forced the plane off the runway and announced the suspension of all its flights operated by Carpatair from Pisa and Bologna.

Last month, a Carpatair flight between Ancona and Rome made an emergency landing soon after take-off.

Earlier in January, another of the Romanian company's planes was forced to make a U-turn following cabin pressure problems which obliged passengers to use oxygen masks.

On January 10 the company issued a statement, denying any reliability problems and denouncing a "media campaign" against it fuelled by "Italian trade unions and pilots" unhappy with Carpatair's partnership with Alitalia.

Carpatair signed the flight-sharing deal with Alitalia last September.

For Valentine's Day, Cupid ditches arrows, opts for e-cards

Admit it. You've always wanted to love like John Travolta.

(Credit:
Screenshot by Chris Matyszczyk/CNET)

Romance isn't dead.

It's merely been reduced to the level of a friend request, a poke, and a privacy control.

Often in that order.

How else can one interpret the staggeringly predictable research -- performed on behalf of SOASTA, the oddly named company that performs cloud and mobile testing -- that suggests more than a third of American human beings will send an e-card for Valentine's Day?

It's true that some e-cards can be amusing, uplifting, even offering an instant surprise on an otherwise moribund day. But can they truly incite a loving feeling on America's most commercially amorous day of the year?

You will be stunned into loving only yourself for the rest of your days when I tell you that -- of the 2,474 American adults surveyed -- men seem a little keener on Valentine e-cards than women.

Indeed, this research offered that 47 percent of men between the ages of 35 and 44 indicated that the love of their life deserved merely a few clicks and a canned expression of love.

Next in enthusiasm were men aged 18-34, 41 percent of whom will let their fingers do the loving.

But let's not besmirch these men any more than they deserve. 41 percent of women aged 18-34 also claimed that e-cards were their chosen method to stroke their chosen one.

Clearly, convenience is at the heart of this e-card enthusiasm, just as it is at the heart of modern romance.

Respondents were radiant at the idea that e-cards are free. 35 percent beamed at the fact that they offer the possibility of animation. And a deeply serious 34 percent felt the need to point out they were environmentally friendly.

A surprisingly paltry 6 percent admitted that they loved e-cards because you could happily include NSFW content.

More Technically Incorrect

Because ours is an acquisitive society, those who send these free, convenient things to express their temporarily undying love actually expect something in return.

A kiss is expected by 8 percent. A fulsome 10 percent expect sex. They must be among those who believe you can get something for nothing.

There will be those who reach for their Latin and mutter: "Sic transit tragoedia mundi." (Oh, look it up, e-carders.)

But when a whole new personal version of oneself is being created and spun online, who can be surprised that other expressions of love might seem not merely passe but also downright unexpressive?

E-cards surely allow you a far greater breadth than paper cards or balloons to display precisely what you really feel about the most important person in your life.

Which, in the case of 3 percent of the respondents in this moving survey, is "the hot receptionist at work."

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.)

Body of Missing Mom Reportedly Found in Turkey

The body of an American woman who went missing while on a solo trip to Turkey has been pulled from a bay in Istanbul, and nine people have been held for questioning, according to local media.

Sarai Sierra, 33, was last heard from on Jan. 21, the day she was due to board a flight home to New York City.

The state-run Andolu Agency reported that residents found a woman's body today near the ruins of some ancient city walls in a low-income district, and police identified the body as Sierra.

Rep. Michael Grimm, R-NY, who with his staff had been assisting the Sierra family in the search, said he was "deeply saddened" to hear the news of her death.

"I urge Turkish officials to move quickly to identify whomever is responsible for her tragic death and ensure that any guilty parties are punished to the fullest extent of the law," he said in a statement.

The New York City mother, who has two young boys, traveled to Turkey alone on Jan. 7 after a friend had to cancel. Sierra, who is an avid photographer with a popular Instagram stream, planned to document her dream vacation with her camera.

"It was her first time outside of the United States, and every day while she was there she pretty much kept in contact with us, letting us know what she was up to, where she was going, whether it be through texting or whether it be through video chat, she was touching base with us," Steven Sierra told ABC News before he departed for Istanbul last Sunday to aid in the search.

Steven Sierra has been in the country, meeting with U.S. officials and local authorities, as they searched for his wife.

On Friday, Turkish authorities detained a man who had spoken with Sierra online before her disappearance. The identity of the man and the details of his arrest were not disclosed, The Associated Press reported.

The family said it is completely out of character for the happily married mother, who met her husband in church youth group, to disappear.

She took two side trips, to Amsterdam and Munich, before returning to Turkey, but kept in contact with her family the entire time, a family friend told ABC News.

Further investigation revealed she had left her passport, clothes, phone chargers and medical cards in her room at a hostel in Beyoglu, Turkey.

There is something magical about waking up to discover it has snowed during the night. But there's no powdery white blanket when it snows on exoplanet HD 209458b. Snow there is black, smoky and hot as hell – resembling a forest fire more than a winter wonderland. Put it this way: you won't be needing mittens.

HD 209458b belongs to a family called hot Jupiters, gas-giant planets that are constantly being roasted due to their closeness to their sun. By contrast, the gas giants in our immediate neighbourhood, including Jupiter, are frigid, lying at the solar system's far reaches.

HD 209458b is also noteworthy because it is tidally locked, so one side is permanently facing towards its star while the other is in perpetual night. On the face of it, these conditions wouldn't seem to invite snow: temperatures on the day side come close to 2000° C, while the night side is comparatively chilly at around 500° C.

Snow made of water is, of course, impossible on this scorched world, but the drastic temperature differential sets up atmospheric currents that swirl material from the day side to night and vice versa. That means that any substances with the right combination of properties might be gaseous on the day side and then condense into a solid on the night side, and fall as precipitation. Say hello to titanium oxide snow.

Stuck on the surface

Although oxides of titanium make up only a small component of a hot Jupiter's atmosphere, these compounds have the right properties to fall as snow. But there was a snag that could have put a stop to any blizzards. Older computer models of hot Jupiters suggested that titanium oxides condensing in the air on the night side would snow – and remain on the relatively cool surface forever. "Imagine on Earth if you had no mechanism to evaporate water, it would never rain," says Vivien Parmentier of the Côte d'Azur Observatory in Nice, France.

Now he and colleagues have created a more detailed 3D computer model that shows that the snow can become a gas again as it falls and the temperature and pressure increase. Strong updraughts can then blow the titanium oxides back to the upper atmosphere. "The gas can come back on the top layers and snow again and again," says Parmentier.

Snowfall on HD 209458b would be like none you've ever seen. Though titanium dioxide is white and shiny, for example, the snowflakes would also contain silica oxides from the atmosphere, making them black. Since the atmosphere is also dark, snowstorms on the planet would be a smoky affair, the opposite of the white-outs we get on Earth. "It would be like being in the middle of a forest fire," says Parmentier.

Although the team studied a particular hot Jupiter, their model should apply equally to other planets of this type, suggesting hot snow is a common occurrence. Parmentier says we may have already spotted snow clouds on another hot Jupiter, HD 189733b, as spectral analysis of the planet suggests the presence of microscopic particles in its atmosphere.

David Sing of the University of Exeter, UK, who helped identify such particles on HD 189733b, says the team's new model goes a long way to explaining how titanium oxides behave on hot Jupiters. "We're pretty used to water condensing on Earth; there it is titanium because the temperatures are so much hotter."

Hot, black snow – now that would be something to wake up to.

Mystery persists in Mexico oil firm blast after 33 die

MEXICO CITY: The cause of a deadly explosion at the headquarters of Mexico's state-owned oil firm remained shrouded in mystery Friday, with authorities investigating if it was an accident or an attack 24 hours later.

As the toll jumped to 33 dead and 121 injured, government and Pemex company officials had yet to pinpoint what was behind the blast that ripped through the annex of the firm's Mexico City skyscraper Thursday afternoon.

The blast erupted amid a debate over plans by President Enrique Pena Nieto to modernize Pemex and attract more outside investments to the old state monopoly, which has suffered deadly industrial accidents as recently as last year.

"The government is determined to find the truth in this incident, whatever it is; whether it was an accident, whether it was carelessness, whether it was an attack," Attorney General Jesus Murillo Karam told a news conference.

"We don't want to leave anything to the imagination," he said as rescuers wound down the search, with rescuers focusing on two final locations. The last body was pulled out of the rubble at around noon.

Earlier, Pemex director general Emilio Lozoya Austin said the explosion appeared to have been an accident, though he insisted that all lines of investigation remained open.

"It appears that this is what one can observe as part of what experts refer to as an accident," he told the Televisa network.

A civil protection spokesman told AFP Thursday that witnesses had reported a gas build-up in an electricity supply room, but it was unclear whether it was the source of the disaster.

Pemex had indicated before the blast was confirmed that the building was evacuated due to an electrical failure.

Murillo Karam said there was no evidence of fire in the victims or debris. Investigators from the army, navy, federal police, prosecutor's office and two foreign firms were involved in the probe.

Hundreds of firefighters, police and soldiers aided by dogs dug through rubble for almost 24 hours straight, with the help of floodlights and cranes after the blast caused the mezzanine of the annex to collapse.

Thousands of people work in the Pemex complex, but officials said the area hit by the blast has four levels and housed 200 to 250 employees.

The government said two more locations were to be searched after they sifted through 39. Mexican Red Cross coordinator Isaac Oxenhaut had indicated earlier that the mission to rescue survivors or search for bodies was over.

"We did a sweep with other organizations, we brought dogs again," he told reporters. "We rule out there being any trapped victims."

Soldiers spent the day clearing mounds of debris from the area, which was strewn with piles of concrete, computers and office furniture.

The Mexican Congress held a minute of silence while Pemex said 52 people remained in hospitals.

Officials stressed that the blast will not interrupt production at the oil giant, the world's fourth-largest crude producer with an output of around 2.5 million barrels per day.

David Shields, a Pemex expert and author of the book "Pemex: The Oil Reform," said whatever the investigation determines will influence the debate over the company's future.

"If it was an attack, the repercussions will be on national security. If they determine that it was a maintenance problem, they will have to establish if it was the failure of the union or a contractor," Shields told AFP.

Pena Nieto has not given details about his plans for Pemex, but he insists it will not be privatized.

The company has experienced deadly accidents at its oil and gas facilities in the past. Last year, a huge explosion killed 30 people at a gas plant near the northern city of Reynosa, close to the US border.

The previous worst incident took place in December 2010, when an oil pipeline exploded after it was punctured by thieves in the central town of San Martin Texmelucan, leaving 29 dead and injuring more than 50.

In October 2007, 21 Pemex workers died during a gas leak on an oil platform in the Gulf of Mexico. Most drowned when they jumped into the sea in panic.

Powertrekk fuel cell charger to be released in Spring

Along with a fuel cell puck, the PowerTrekk gives your iPhone a bit of juice. Just add water.

While it's been circulating around at trade shows for a while, including Mobile World Congress 2011 and CES 2012, the PowerTrekk phone charger is slated to finally come to the U.S. at the end of this quarter.

Although the $229 device is peddled as a charger that can simply juice up your phone on water alone, it's not quite that simple.

To use the PowerTrekk, you also have to purchase a $4 PowerTrekk Pukk. Once you add a small amount of water (about half a shot), and add a one-time-use Pukk, the latter will immediately begin separating the hydrogen from the water, using it as fuel to charge your handset.

Each Pukk will produces 2.5 watts at 5 volts, which is good for about one full iPhone charge. If there is electricity available, however, you can also charge the separate internal battery in the PowerTrekk so it can power your phone later on.

Power your phone in an emergency

When I handled the unit at iWorld in San Francisco, it was indeed very lightweight despite its industrial look, and in a situation where there is no sun, I can see it coming in handy.

However, there is much debate about how useful a product like this can be. Not only is it rather cumbersome in shape, but you'll need to continually buy more Pukks in order to use the device multiple times. Compared to solar chargers and chargers that run on kinetic energy, this can become wasteful and pricey.
