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

Gov's Handling of Sandusky Case Under Investigation

The newly-elected attorney general of Pennsylvania is going after the state's governor, Tom Corbett, who was attorney general when child sex allegations against Penn State coach Jerry Sandusky were first brought forward.

Kathleen Kane, a Democrat who was sworn in as attorney general on Jan. 15, said that she will name a special prosecutor in the coming days to investigate Corbett's handling of the Sandusky case. Corbett is a Republican.

The investigation will look specifically at why it took the attorney general's office three years to bring criminal charges against Sandusky while he continued to have access to children.

"Attorney General Kane will appoint a special prosecutor to lead the office's internal investigation into how the Sandusky child abuse investigation was handled by the Office of the Attorney General," Kane's office said in a statement released today.

Corbett's attorney general's office was first notified of the allegations against Sandusky in 2008 when a high school student told his mother and school that Sandusky had molested him. The local district attorney passed the allegation on to the attorney general, then Corbett. Corbett convened a grand jury.

It wasn't until 2011 that sex abuse charges were filed against Sandusky while Corbett had since become governor. Sandusky was convicted on 45 counts of sex abuse in June 2012.

The charges sent shockwaves throughout Pennsylvania, as Penn State's president, two top officials, and legendary coach Joe Paterno all lost their jobs over the scandal.

"Why did it take 33 months to get Sandusky off the streets? Was the use of a grand jury the right decision? Why were there so few resources dedicated to the investigation? Were the best practices implemented?" the statement from Kane's office read.

"At the end of this investigation, we will know the answers to these questions and be able to tell the people of Pennsylvania the facts and give them answers that they deserve," the statement said.

Describing an interview Kane gave the New York Times, the Times said Kane suggested that Corbett did not want to upset voters or donors in the Penn State community before his gubernatorial run in 2009.

Corbett has denied those suggestions. His office did not immediately return calls for comment.

Kane's office preemptively fought back against the idea that the investigation is politically motivated. Kane, a Democrat, defeated the incumbent attorney general, Linda Kelly, a Republican in November 2011. Corbett is a Republican.

"The speculation that this is about politics is insane," a staff member in Kane's office told ABC News today. "You go anywhere in Pennsylvania and anywhere across the country and you'll find individuals asking, 'why did it take three years? Why was there a grand jury? Why make these kids talk to 30 different people about what happened?"

Swarm-mongering: Brainless blobs flock together

Birds of a feather flock together and now so do brainless, inanimate blobs. Made of microscopic particles, the artificial swarms could shed light on the mysterious mechanisms behind the natural swarming seen in fish and birds. They might also lead to materials with novel properties like self-healing.

Animals such as birds, fish and even humans that move together in swarms have individual intelligence, but Jérémie Palacci of New York University and colleagues wondered whether inanimate objects could also swarm. "From a physicist's point of view, if many different systems behave in the same way there must be an underlying physical rule," he says.

To explore this idea, the team created microscopic plastic spheres, each one with a cubic patch of haematite, an iron oxide, on its surface. When submerged in hydrogen peroxide, the spheres spread out in a disordered fashion. The team then shone blue light on the particles, causing the haematite cubes to catalyse the breakdown of any nearby hydrogen peroxide into water and oxygen. As hydrogen peroxide concentration dropped temporarily in these regions due to the reaction, osmotic forces cause more hydrogen peroxide to flow into them, and that in turn buffets the spheres. The whole process then repeats.

Self-healing swarm

When two spheres come close enough to each other, the balance of chemical forces shifts so that the two spheres are attracted. If there are enough spheres in the same place they will cluster together to form shapes of symmetrically arranged particles, which the team call crystals (see video, above). These crystals continue to be buffeted by the movement caused by the breakdown of hydrogen peroxide – but now they move together as one object, replicating a life-like swarm. Switch off the light, however, and the reaction stops, causing the crystal to lose the forces that hold it together, and the particle distribution becomes disordered once again.

"This system shows that even though the particles have no social interaction or intelligence, you can exhibit collective behaviour with no biology involved," says Palacci. Since the haematite is magnetic, it is even possible to steer the crystals in one direction by applying a magnetic field. Such control might be useful if the artificial swarms are to be harnessed for applications.

As the particles automatically fill any gaps that form in the crystal, again thanks to the chemical dynamics of the system, they could be used to create a self-assembling, self-healing material. The work is published in the journal Science today.

Schooled by fish

Iain Couzin of Princeton University says these kinds of systems are very useful for studying biological collective behaviour because researchers have complete control over their interactions – unlike natural systems.

His team has its own swarming experiment published in the same issue of Science, based on schools of fish that prefer to stay in shade. Their paper shows that shining a light on some of the fish in the school causes them to speed up, to get away from the light. But as a result, non-illuminated fish also speed up, even though, if acting purely as individuals, they would have had no reason to do so. "We show just by using simple interactions that schools can have a sense of responsiveness to the environment that individuals do not have," he says.

Couzin sees no reason why such behaviour should be limited to natural systems. "In future it may be possible to create systems of particles that can make collective decisions – something we often think of as only possible in biological systems," he says.

Chua Chu Kang TC new managing agent's plans to improve services

SINGAPORE: Feedback from residents of estates managed by Chua Chu Kang Town Council will be tracked more efficiently, while officers can directly record defects into the estate maintenance system using their smartphones.

These are some of the changes planned by the town council's new managing agent, CPG Facilities Management (CPGFM).

It was appointed following an open tender and took over on 1 February from UGL Services Esmaco Operations, whose contract with the town council ended on 31 January.

CPGFM, whose contract is for four years, will manage the common property of more than 70,000 residential and commercial units in Chua Chu Kang Group Representation Constituency (GRC).

There are five divisions in the GRC - Bukit Gombak, Chua Chu Kang, Keat Hong, Nanyang and Yew Tee and Hong Kah North.

The managing agent plans to leverage technology to improve services.

Mr Zaqy Mohamad, chairman of Chua Chu Kang Town Council, said the transition and handover have been smooth and seamless.

CPGFM is a subsidiary of CPG Corporation, which was formed in April 1999 with the corporatisation of the former Public Works Department.

It is also the managing agent of Ang Mo Kio and Tampines town councils.

Nokia begins work on graphene, world's strongest material

Forget diamonds, graphene is now the world's hardest material. And, all sorts of developers most likely want to get their hands on it.

Nokia looks to be ahead of the game in this graphene race. The Finnish mobile phone maker announced today that it was one of the recipients of a $1.35 billion grant from the European Union to do research and development on the super-material over the next 10 years.

"Nokia is proud to be involved with this project, and we have deep roots in the field -- we first started working with graphene already in 2006," Nokia's CTO Henry Tirri said in a statement. "Since then, we have come to identify multiple areas where this material can be applied in modern computing environments. We've done some very promising work so far, but I believe the greatest innovations have yet to be discovered."

Besides being the hardest substance in the world -- 300 times stronger than steel -- graphene has all sorts of other noteworthy qualities. It is also the thinnest object ever obtained by man -- measuring just one atom thick -- and the lightest. It is made of a 2D crystal and looks a bit like scotch tape, only infinitely thinner. Graphene is also transparent, bendable, and a far better conductor than copper.

If Nokia is successful in its development of the material, it will be able to build cell phones that are extremely light, durable, and less susceptible to overheating.

"When we talk about graphene, we've reached a tipping point. We're now looking at the beginning of a graphene revolution," research leader at Nokia Research Center Jani Kivioja said in the statement. "Before this point in time, we figured out a way to manufacture cheap iron that led to the Industrial Revolution. Then there was silicon. Now, it's time for graphene."

Here is a video by Cambridge University about the properties of graphene:

The sinkhole that formed in the southern Chinese city of Guangzhou (pictured) is, unfortunately, not a new occurrence for the country.

Many areas of the world are susceptible to these sudden formations, including the U.S. Florida is especially prone, but Guatemala, Mexico, and the area surrounding the Dead Sea in the Middle East are also known for their impressive sinkholes. (See pictures of a sinkhole in Beijing that swallowed a truck.)

Arias' Lawyer Shows Ex-Boyfriend's Lewd Photos

Accused murderer Jodi Arias was kept away from the Mormon friends of her lover Travis Alexander and their torrid sex affair was kept secret by Alexander, even as he sent lewd photos of himself to her online, according to court testimony today.

The testimony in Arias' trial for killing Alexander in 2008 was intended to bolster the defense's argument that she killed him in self defense, that Alexander was a sexual deviant who treated Arias as his "dirty little secret."

Arias' attorneys introduced as evidence photos that Alexander took of his penis and sent to Arias, part of a string of graphic messages and sexual phone calls the two engaged in while Alexander, an elder in the Mormon church, was supposed to be chaste.

Today's witness was the latest in a string called by the defense, including Alexander's former girlfriend Lisa Daidone, who told the court that Alexander had professed to be a virgin.

Daniel Freeman continued his testimony today, describing how he was a friend of both Arias and Alexander but that Alexander kept Arias distanced from his Mormon pals.

"Travis had made more friends at (the Mormon) ward, and had (Ultimate Fighting Championship) fight nights at his house many times, and Jodi was in town, but she wasn't there," Freeman said.

"There was that group of friends, them and Jodi, two different groups, and so Lisa [Daidone] and friends from church were there, but Jodi wasn't there," Freeman said.

Alexander's behavior, the defense hopes to prove, shows that he mistreated Arias.

Arias, 32, is on trial for murdering Alexander, whom she dated for a year and continued to have a sexual relationship for a year after that. Her attorneys claim that Alexander was abusive and controlling toward Arias, and that she was forced to kill him.

Freeman described how he took a trip with his sister, Alexander, and Arias, and how Alexander had asked him to come along so that he and Arias "would not get physical."

"I don't know that I can say he didn't want to be alone with her, but he liked that when I was there, and my sister was there. They weren't as physical," Freeman said.

Freeman admitted that he had no idea Alexander and Arias had been having a sexual relationship the entire time they were together. He said Alexander never mentioned that to his friends.

In fact, Freeman noted that Alexander was considered to be a church elder when he baptized Arias into the Church of Latter-Day Saints. Both a church elder and a convert were expected to abide by the church's strict law of chastity, which banned any sexual relations outside of marriage.

"One thing people give up in this baptism process was sex," prosecutor Juan Martinez said. "Did you know she was having oral sex with Mr. Alexander at the time of her baptism? Would that be an insincere baptism?"

"She would not be ready to be baptized in that case," Freeman said.

"You were asked about Miss Arias, whether she was worthy of baptism if she was performing oral sex, but what about the elder receiving oral sex?" defense attorney Kirk Nurmi said.

"They would not be worthy of performing that ordinance at that time until they had gone through repentance," Freeman said. "They would go to a discipline council and could face excommunication or a probation period or have their priesthood removed."

Freeman said that Alexander never confessed to having a sexual relationship with Arias.

Freeman's testimony came on the third day of the defense's attempt to paint Alexander as a controlling, sex-obsessed liar who was cruel to Arias. Other witnesses have said that Alexander cheated on other women he dated with Arias, and lied to his friends and family about their relationship.

The defense also had Freeman point out that Alexander was strong and fit. They are expected to conclude that Alexander was physically threatening Arias when she killed him.

2 new commercial belts to bring jobs closer to homes

SINGAPORE: Jobs will be brought nearer to the homes to help ease the congestion in the city centre, with two new commercial belts.

The government, which outlined these developments in its Land Use Plan, will also make it easier for people to use public transport. And, it hopes to see 75 per cent of all journeys made by public transport by 2030, compared with the current 60 per cent.

The first new commercial belt is the North Coast Innovation Corridor, spanning Woodlands Regional Centre, Sembawang, the future Seletar Regional Centre and Punggol, to be ready in 10 to 15 years.

Seletar Regional Centre, for example, will be a major employment node for people living in the north and north east. There'll be more land for new business activities when the existing shipyard facilities in Sembawang are phased out.

By 2030, it'll be easier to get around using the Cross Island Line, Thomson Line and the new North-South Expressway.

Within the regional hubs, there are plans to start community bus services, which will operate during specific periods of the day.

The other commercial belt is the Southern Waterfront City - from Marina Bay along the waterfront from Keppel, through Telok Blangah to Pasir Panjang Terminal. It'll have more commercial and housing developments after 2027.

To serve the expected increase along the North-South corridor and optimise the use of roads, the government may introduce what it calls a "reversible flow" scheme along certain expressways.

This means the traffic can flow in one direction during the morning peak hours and move in the opposite direction during the evening peak period.

Microsoft Surface sales well below shipments, says iSuppli

Surface RT tablet.

CNET)

Sales of Microsoft's first Surface tablet fell well short of the 1 million mark, while return rates were high, IHS iSuppli told CNET.

Shipments of the Surface RT device, which debuted last quarter, into the channel were about 1.25 million, but sales out of the channel "were significantly lower, maybe on the order of 55 to 60 percent of that figure," said Rhoda Alexander, an analyst at iSuppli, citing the market research firm's estimates.

That would put sales in the range of between roughly 680,000 and 750,000 based on those percentages.

That kind of "sales out" percentage is not unusual, however, according to Alexander, adding that she has seen similar percentages with newly introduced
Android devices.

And, needless to say, almost every manufacturer's sales-out figure pales against Apple's, the gold standard, where the percentage is typically in the mid to high 90 percent range or even 100 percent.

And Alexander said she sees little evidence of continued production of the Microsoft RT device -- which runs a limited version of
Windows 8 on top of an ARM processor -- in the first quarter because Microsoft is still trying to sell off inventory.

But that inventory carryover is also not unique to Microsoft. The Amazon
Kindle Fire, when it was first introduced, had excess inventory that carried over into the following quarter. As a result, Amazon temporarily cut production, Alexander said.

Surface RT has other challenges, too. The return rate on the device was "very high," Alexander said. "If you put the high return rate together with low sell-through [sales out] rate, that's indicative of a problem," she said, adding, again, that the Kindle Fire initially had very high return rates and low sell-through.

Why the high return rates? "It seems to be linked in a lot of cases to a steep learning curve of the [Windows 8] OS -- which is not necessarily intuitive," she said.

And another problem possibly looms big this year. There is a "distinct lack of interest" from device makers in pursuing RT devices at the moment, she said.

For Microsoft partners the question is, "where is the win for us?" -- according to Alexander.

During last week's earnings conference call, Chief Financial Officer Peter Klein repeated a number of times that Surface contributed to revenue. "Certainly this quarter [Surface] was a contributing factor to revenue growth in the Windows business," Klein said.

During the call, Microsoft cited Surface as a part of non-OEM revenue that grew 40 percent.

Microsoft has not talked about sales figures. And the company would not provide a number when contacted.

Microsoft is about to bring out a second line of tablets, the Surface Pro, that runs the full version of Windows 8 on top of a mainstream Intel processor. Alexander says she sees more momentum industrywide for these kinds of devices.
