Astrophile: A scorched world with snow black and smoky

Astrophile is our weekly column on curious cosmic objects, from the solar system to the far reaches of the multiverse

Object: Titanium oxide snow
Location: The hot-Jupiter planet HD 209458b

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.

Super Bowl from the sidelines: Tech readiness is priority No. 1

View from main CBS control truck at the Superdome.

It's always a treat to watch the game coverage by the peerless NFL on CBS team, which is the very best in the business. And backing up our amazing group of analysts and experts in front of the camera is a trained crew of CBS Sports production and technical pros behind the scenes.

Their No. 1 priority is to deliver the perfect angle of every play, along with the sophisticated replays, zoom, and hyper-broadcast detail that TV viewers have grown to love. The production logistics and technical complexity associated with broadcasting the Super Bowl are astounding. This year, CBS Sports will have 62 cameras at the Superdome covering the game, along with dozens of replay devices. When you are able to capture virtually every detail of the action, the hard part becomes choosing the angles and replays wisely and making sure you don't interfere with the broadcast.

In the mix will be some 4K cameras, which allow for stunning zooming capabilities, as well as the CBS sky cam, which glides over the field on a cable, capturing all. Orchestrating and syncing all the associated gear -- including switchers, audio consoles, graphics gear packages, servers HD cam decks, and a whole lot of cable -- is a massive undertaking. Beyonce is not the only one rehearsing ahead of Sunday -- there have been production rehearsals every day this week to get ready.

I'm in awe of the process and all of my colleagues at CBS Sports who make the magic happen. The final countdown has begun, so follow me on Twitter at and stay tuned!

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

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?"

Mind-meld brain power is best for steering spaceships

TURNS out two heads really are better than one. Two people have successfully steered a virtual spacecraft by combining the power of their thoughts - and their efforts were far more accurate than one person acting alone. One day groups of people hooked up to brain-computer interfaces (BCIs) might work together to control complex robotic and telepresence systems, maybe even in space.

A BCI system records the brain's electrical activity using EEG signals, which are detected with electrodes attached to the scalp. Machine-learning software learns to recognise the patterns generated by each user as they think of a certain concept, such as "left" or "right". BCIs have helped people with disabilities to steer a wheelchair, for example.

Researchers are discovering, however, that they get better results in some tasks by combining the signals from multiple BCI users. Until now, this "collaborative BCI" technique has been used in simple pattern-recognition tasks, but a team at the University of Essex in the UK wanted to test it more rigorously.

So they developed a simulator in which pairs of BCI users had to steer a craft towards the dead centre of a planet by thinking about one of eight directions that they could fly in, like using compass points. Brain signals representing the users' chosen direction, as interpreted by the machine-learning system, were merged in real time and the spacecraft followed that path.

The results, to be presented at an Intelligent User Interfaces conference in California in March, strongly favoured two-brain navigation. Simulation flights were 67 per cent accurate for a single user, but 90 per cent on target for two users. And when coping with sudden changes in the simulated planet's position, reaction times were halved, too. Combining signals eradicates the random noise that dogs EEG signals. "When you average signals from two people's brains, the noise cancels out a bit," says team member Riccardo Poli.

The technique can also compensate for a lapse in attention. "It is difficult to stay focused on the task at all times. So when a single user has momentary attention lapses, it matters. But when there are two users, a lapse by one will not have much effect, so you stay on target," Poli says.

NASA's Jet Propulsion Lab in Pasadena, California, has been observing the work while itself investigating BCI's potential for controlling planetary rovers, for example. But don't hold your breath, says JPL senior research scientist Adrian Stoica. "While potential uses for space applications exist, in terms of uses for planetary rover remote control, this is still a speculative idea," he says.

Taiwan premier resigns over flagging economy

TAIPEI: Taiwanese Premier Sean Chen said Friday he has stepped down for health reasons, after the cabinet he heads came under fire for its poor handling of the economy.

"I have some health problems ... and I need to completely change my life and work style to reverse the situation," the 63-year-old finance expert told a press conference to announce his resignation.

"I believe that the economy will improve in the coming year. We have worked very hard on the planning for long-term issues and I hope everybody will continue to support the new team."

Deputy premier Jiang Yi-huah, 53, a scholar-turned-politician and a former interior minister, will take over his job, Chen said.

Chen's departure came as Taiwan's economy grew 1.25 percent in 2012 from a year ago at the slowest pace in three years due to shrinking exports.

Chen, who previously headed the Financial Supervisory Commission, the main industry regulator, had a tense term since taking office as premier in early 2012.

His cabinet frequently came under attacks over the sluggish economy and other controversial policies, with the opposition repeatedly demanding his resignation.

Last year, Chen survived a parliamentary no-confidence vote - only the second in Taiwan history - over what opposition lawmakers deemed as his cabinet's failure to curb rising unemployment and inflation.

Under Taiwan's political system the premier heads the cabinet and is appointed by the president.

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.

Keep rainforests – they drive the planet's winds

WHAT creates the wind? Anyone will tell you that temperature differences are key. Hot air rises and is replaced by cooler air surging in beneath. Except that maybe the explanation found in every textbook is too simple.

What if, instead, the winds that drive atmospheric circulation are mainly created by the condensation of moisture? Much of this occurs over rainforests as water evaporates or is transpired from the trees. The physicists and foresters behind this controversial idea say that if we chop down the forests, we will lose the winds - and the rains they bring with them.

The physical process itself is not in dispute. Whenever water vapour condenses to form droplets, its volume is reduced, lowering the pressure. Air moves in, creating wind.

Climate scientists have always regarded this as a trivial effect. Criticism has been heaped on the theory since it was first aired four years ago. "This is not a mysterious effect. It is small and included in some atmospheric models," says Isaac Held of the US National Oceanic and Atmospheric Administration in Princeton, New Jersey.

But physicist Anastassia Makarieva of St Petersburg University in Russia says the pressure gradients it would create "have never received a theoretical investigation". Her calculations suggest that the condensation of billions of litres of water above giant forests produces a giant effect (Atmospheric Chemistry and Physics, doi.org/kbx).

Co-author Douglas Sheil at Southern Cross University in Lismore, Australia, says critics have yet to explain why they think Makarieva is wrong. Until they do, he said, "this looks like a powerful mechanism that governs weather patterns round the world".

Judith Curry of the Georgia Institute of Technology, an author of the standard textbook Thermodynamics of Atmospheres and Oceans, is encouraging. "The process they describe is physically correct," she said. "The main question is its relative magnitude compared with other processes." She thinks it could explain why climate models do not get monsoons and hurricanes right.

Nobody doubts that forests recycle rain through evaporation and transpiration. But this is the first suggestion that this recycling process also whips up the winds that suck moist ocean air across continents.

The implications are huge. "In standard theories, if we lose forests the rainfall in the continental interiors generally declines by 10 to 30 per cent. In our theory, it is likely to decline by 90 per cent or more," says Sheil.

But it is not all bad news. If lost forests are replanted, the theory suggests, then the winds they generate could return rain to even the most arid lands. After all, the Sahara was lush swampland 6000 years ago.

Tumblr avoids porn label and adds mature rating to iOS app

Tumblr's iPhone app.

(Credit:
Tumblr)

Tumblr looks to be trying to avoid the porn-war that recently harangued the 500px photo app and Twitter's Vine app.

The microblogging company threw up a 17-and-over age warning for its iOS app for all new users and any people updating their app to the 3.2.4 version, which was released today.

"You must be at least 17 years old to download this app," Tumblr writes in its description of the app in the iTunes App Store, because it contains "Frequent/Intense Sexual Content or Nudity."

The app's upgrade says only that it will carry out "small bug fixes." However, when users click on the 3.2.4 version, they're forced to confirm they are over the age of 17. "Tumblr contains age-restricted material," the app says when upgrading. "Tap OK to confirm that you are 17 or over. Your content will then begin downloading immediately."

It's unclear exactly why Tumblr changed its app to contain a mature rating. But it's no secret that certain blogs on the site contain "sexual content" and "nudity." In an interview last June, Tumblr founder David Karp noted that 2 percent to 4 percent of the traffic on Tumblr is porn-related.

Tumblr's 17+ rating comes as 500px and Vine have been scrutinized for making porn easily accessible. When Twitter released the Vine app last week, many users quickly found a handful of videos featuring male exhibitionism and other activity. Apple quickly stopped promoting Vine in its App Store.

500px had an even more severe reprimand. After complaints of the app containing pornographic images and material, Apple pulled it from
iTunes. Now that 500px has added warnings and a 17+ rating, Apple allowed it back into the App Store.

Maybe Tumblr is acting preemptively with its new 17+ rating. CNET contacted Tumblr for comment. We'll update the story when we get more information.

New Theory on How Homing Pigeons Find Home

Jane J. Lee

Homing pigeons (Columba livia) have been prized for their navigational abilities for thousands of years. They've served as messengers during war, as a means of long-distance communication, and as prized athletes in international races.

But there are places around the world that seem to confuse these birds—areas where they repeatedly vanish in the wrong direction or scatter on random headings rather than fly straight home, said Jon Hagstrum, a geophysicist who authored a study that may help researchers understand how homing pigeons navigate.

Hagstrum's paper, published online Wednesday in the Journal of Experimental Biology, proposes an intriguing theory for homing pigeon disorientation—that the birds are following ultralow frequency sounds back towards their lofts and that disruptions in their ability to "hear" home is what screws them up.

Called infrasound, these sound waves propagate at frequencies well below the range audible to people, but pigeons can pick them up, said Hagstrum, who works at the U.S. Geological Survey in Menlo Park, California.

"They're using sound to image the terrain [surrounding] their loft," he said. "It's like us visually recognizing our house using our eyes."

Homeward Bound?

For years, scientists have struggled to explain carrier pigeons' directional challenges in certain areas, known as release-site biases.

This "map" issue, or a pigeon's ability to tell where it is in relation to where it wants to go, is different from the bird's compass system, which tells it which direction it's headed in. (Learn about how other animals navigate.)

"We know a lot about pigeon compass systems, but what has been controversial, even to this day, has been their map [system]," said Cordula Mora, an animal behavior researcher at Bowling Green State University in Ohio who was not involved in the study.

Until now, the two main theories say that pigeons rely either on their sense of smell to find their way home or that they follow the Earth's magnetic field lines, she said.

If something screwed up their sense of smell or their ability to follow those fields, the thinking has been, that could explain why pigeons got lost in certain areas.

But neither explanation made sense to Hagstrum, a geologist who grew interested in pigeons after attending an undergraduate lecture by Cornell biologist William Keeton. Keeton, who studied homing pigeons' navigation abilities, described some release-site biases in his pigeons and Hagstrum was hooked.

"I was just stunned and amazed and fascinated," said Hagstrum. "I understand we don't get dark matter or quantum mechanics, but bird [navigation]?"

So Hagstrum decided to look at Keeton's pigeon release data from three sites in upstate New York. At Castor Hill and Jersey Hill, the birds would repeatedly fly in the wrong direction or head off randomly when trying to return to their loft at Cornell University, even though they had no problems at other locations. At a third site near the town of Weedsport, young pigeons would head off in a different direction from older birds.

There were also certain days when the Cornell pigeons could find their way back home from these areas without any problems.

At the same time, homing pigeons from other lofts released at Castor Hill, Jersey Hill, and near Weedsport, would fly home just fine.

Sound Shadows

Hagstrum knew that homing pigeons could hear sounds as low as 0.05 hertz, low enough to pick up infrasounds that were down around 0.1 or 0.2 hertz. So he decided to map out what these low-frequency sound waves would have looked like on an average day, and on the days when the pigeons could home correctly from Jersey Hill.

He found that due to atmospheric conditions and local terrain, Jersey Hill normally sits in a sound shadow in relation to the Cornell loft. Little to none of the infrasounds from the area around the loft reached Jersey Hill except on one day when changing wind patterns and temperature inversions permitted.

That happened to match a day when the Cornell pigeons had no problem returning home.

"I could see how the topography was affecting the sound and how the weather was affecting the sound [transmission]," Hagstrum said. "It started to explain all these mysteries."

The terrain between the loft and Jersey Hill, combined with normal atmospheric conditions, bounced infrasounds up and over these areas.

Some infrasound would still reach Castor Hill, but due to nearby hills and valleys, the sound waves approached from the west and southwest, even though the Cornell loft is situated south-southwest of Castor Hill.

Records show that younger, inexperienced pigeons released at Castor Hill would sometimes fly west while older birds headed southwest, presumably following infrasounds from their loft.

Hagstrum's model found that infrasound normally arrived at the Weedsport site from the south. But one day of abnormal weather conditions, combined with a local river valley, resulted in infrasound that arrived at Weedsport from the Cornell loft from the southeast.

Multiple Maps

"What [Hagstrum] has found for those areas are a possible explanation for the [pigeon] behavior at these sites," said Bowling Green State's Mora. But she cautions against extrapolating these results to all homing pigeons.

Some of Mora's work supports the theory that homing pigeons use magnetic field lines to find their way home.

What homing pigeons are using as their map probably depends on where they're raised, she said. "In some places it may be infrasound, and in other places [a sense of smell] may be the way to go."

Hagstrum's next steps are to figure out how large an area the pigeons are listening to. He's also talking to the Navy and Air Force, who are interested in his work. "Right now we use GPS to navigate," he said. But if those satellites were compromised, "we'd be out of luck." Pigeons navigate from point to point without any problems, he said.

No Device Eliminates Concussion Risk, Experts Say

As the long-term consequences of concussions become clearer, a cottage industry has popped up to sell athletes and worried parents products designed to mitigate risks of concussions that even helmets cannot prevent.

Despite the bold claims of some companies, however, many experts say the Holy Grail in contact sports -- a device that prevents concussions -- simply does not exist. Indeed, experts say, there is no proof that any current device significantly reduces the risk of concussions beyond the protections already provided by helmets.

"Nightline" found several products for sale online that aim to reduce the risk of concussions or even alert parents and coaches when a kid has supposedly taken a concussion-level hit. The claims the manufacturers make are often breathtakingly reassuring.

Concern about the risk of concussion is mounting at every level of the gridiron from the NFL to colleges and even high schools. Concussions are the most common injury among high school football players.

Jennifer Branin, whose son Tyler Branin is one of the stars of the Woodbridge Warriors high school football team in Irvine, Calif., said "it was scary" the first time he had a concussion.

"He had lost his balance on the field," she said. "He got up and tried to continue, but couldn't keep his balance."

Junior Seau Had Brain Disease, Researchers Say Watch Video

She said the effects of the concussion lingered, causing Tyler to miss a week of school and football practice. Even months later, he complained of difficulty concentrating in class.

Parents such as Jennifer Branin, who is president of the team's booster club, and her husband, Andy Branin, a former college football player himself, were looking for a way to support their son's desire to play football while also keeping him safe.

"He wants to play and, as a mom, you may want to put bubble-wrap around them and protect them forever, but that's not going to happen," she said.

So Jennifer Branin decided to do something. She raised money to buy the team helmet inserts by Unequal Technologies for added protection.

Unequal Technologies, one of the highest profile players in this new market, described its product explicitly on the box as "Concussion Reduction Technology," or "CRT." It is a strip of composite material including bullet-proof Kevlar that is designed to stick inside the helmet as a liner to the existing helmet pads.

Unequal Technologies uses its material in products ranging from padded sleeves to shin guards. The company counts NFL players and X-Games athletes among its fans.

On board as paid spokesmen are Philadelphia Eagles quarterback Michael Vick and James Harrison, a linebacker for the Pittsburgh Steelers. Harrison is one of the hardest-hitting guys in the NFL and said he uses Unequal Technology's liners in his helmet.

"I don't know what it's made of but it works," Harrison says in one of Unequal's promotional videos. "I really don't feel like I'm taking a risk."

Vick wasn't wearing the CRT product when he suffered a season-ending concussion in November, but he has since promised that he will be wearing it when he returns to the field next season.

Rob Vito, founder and CEO of the Kennett Square, Pa.-based company, said he worked with scientists to create a military-grade composite material that can help protect athletes from all kinds of injuries from head to toe.

Greater community support helps ex-offenders

SINGAPORE: Greater community support for ex-offenders has paid off -- with overall fewer ex-inmates imprisoned for re-offending -- according to the Singapore Prison Service's annual report card.

However, drug offenders who were released from Drug Rehabilitation Centres recorded a higher percentage of re-offending.

For some inmates who have no family support, they might not have a job or a home to return to after they are released.

Chavez Ong, a specialist in correctional rehabilitation with the Singapore Prison Service, said: "We actually work together with our partners, like the HDB -- we've been liasing with them to look into the (housing) issue.

"We also look into halfway houses for placement. And we also try to reach out to their families again, because for us, family involvement during the rehabilitation process is one of the very crucial factors."

The greater community support for ex-prisoners has paid off. The Singapore Prison Service said that the overall recidivism rate -- which is the rate at which prisoners re-offend and return to jail within two years of release -- fell to 23.6 per cent for those released in 2010, down from 26.7 per cent for those who were released in 2009.

On average, about 9,000 local inmates are released from prison each year. In 1998, the recidivism rate was 44.4 per cent, but in recent years it has hovered around 26 to 27 per cent.

About 20 per cent more employers have joined the effort to hire ex-offenders, which means more inmates found jobs before they were released.

The number of employers who are part of the Singapore Corporation of Rehabilitative Enterprises now stands at 3,457, compared with 2,872 in 2011, and 2,459 in 2010. Most of the jobs are in manufacturing, logistics, and food & beverage.

For a third year running, more inmates found jobs before they were released.

More volunteers have also joined the community outreach programme to support the families of these inmates. The programme now has 390 registered and trained volunteers -- an increase of 69 per cent from 2011.

But for drug offenders, a higher number re-offended. The recidivism rate for those released from the drug rehabilitation centres in 2010 was 27.5 per cent -- slightly higher than the 27.1 per cent of 2009.

To tackle this, repeat drug offenders at higher risk of re-offending must now go through a more robust mandatory supervision programme upon their release.

Besides urine tests and electronic monitoring, there will also be compulsory case work and counselling.

Rubiana Shamsul, a reintegration officer with the Singapore Prison Service, said: "So basically these offenders will actually face challenges when they go back to their old neighbourhood and they would be facing their old circle of friends and that's where the temptation would come in. So from there, we're trying to curb this by having our regular counselling sessions.

"Another challenge they would be facing is finding gainful employment -- we'd like to motivate them to have pro-social activities in their leisure time, so they don't have the temptation to go back to doing what they were doing before."

About 1,000 drug offenders are expected to be supervised this way in 2013 and 2014.

Michael Dell to use personal funds to seek majority control -- report

Dell founder and Chief Executive Michael Dell.

James Martin/CNET)

Just weeks after reports surfaced that Dell was looking to go private, the company's founder appears willing to put his personal funds where his mouth is.

Michael Dell may kick in equity financing of $500 million to $1 billion combined with his 15.7 percent stake in the company to seek majority control of the company, according to Bloomberg. That would push his ownership stake past 50 percent.

With the investment, Dell would be contributing more than half of the total $8 billion to $9 billion equity check. The remainder of the takeover would be financed by debt and "possibly some of the $11 billion of cash Dell reported it had as of September 30," according to Bloomberg.

This follows on the heels of reports that Microsoft may contribute $1 billion to $3 billion and was in talks with Silver Lake Partners to help take Dell private.

However, the WSJ today reported that Microsoft's role in the new company has been a sticking point in negotiations. Though the deal is still expected to stay on track, Microsoft wants to have a say in some of Dell's operations rather than just being a source of funding, according to the WSJ's sources.

Dell, a one-time leading PC maker, has hit hard times of late. The company's stock has continued to lose value as it defends itself against rivals, and despite the many acquisitions it's made over the past several years, there are concerns about how fast those businesses are taking off. Some industry watchers are hoping that going private could give it the reboot that it needs.

Timbuktu’s vulnerable manuscripts are city’s "gold"

French and Malian troops surrounded Timbuktu on Monday and began combing the labyrinthine city for Islamist fighters. Witnesses, however, said the Islamists, who claim an affiliation to al Qaeda and had imposed a Taliban-style rule in the northern Malian city over the last ten months, slipped into the desert a few days earlier.

But before fleeing, the militants reportedly set fire to several buildings and many rare manuscripts. There are conflicting reports as to how many manuscripts were actually destroyed. (Video: Roots of the Mali Crisis.)

On Monday, Sky News posted an interview with a man identifying himself as an employee of the Ahmed Baba Institute, a government-run repository for rare books and manuscripts, the oldest of which date back to the city's founding in the 12th century. The man said some 3,000 of the institute's 20,000 manuscripts had been destroyed or looted by the Islamists.

Video showed what appeared to be a large pile of charred manuscripts and the special boxes made to preserve them in front of one of the institute's buildings.

However, a member of the University of Cape Town Timbuktu Manuscript Project told eNews Channel Africa on Tuesday that he had spoken with the director of the Ahmed Baba Institute, Mahmoud Zouber, who said that nearly all of its manuscripts had been removed from the buildings and taken to secure locations months earlier. (Read "The Telltale Scribes of Timbuktu" in National Geographic magazine.)

A Written Legacy

The written word is deeply rooted in Timbuktu's rich history. The city emerged as a wealthy center of trade, Islam, and learning during the 13th century, attracting a number of Sufi religious scholars. They in turn took on students, forming schools affiliated with's Timbuktu's three main mosques.

The scholars imported parchment and vellum manuscripts via the caravan system that connected northern Africa with the Mediterranean and Arabia. Wealthy families had the documents copied and illuminated by local scribes, building extensive libraries containing works of religion, art, mathematics, medicine, astronomy, history, geography, and culture.

"The manuscripts are the city's real gold," said Mohammed Aghali, a tour guide from Timbuktu. "The manuscripts, our mosques, and our history—these are our treasures. Without them, what is Timbuktu?"

This isn't the first time that an occupying army has threatened Timbuktu's cultural heritage. The Moroccan army invaded the city in 1591 to take control of the gold trade. In the process of securing the city, they killed or deported most of Timbuktu's scholars, including the city's most famous teacher, Ahmed Baba al Massufi, who was held in exile in Marrakesh for many years and forced to teach in a pasha's court. He finally returned to Timbuktu in 1611, and it is for him that the Ahmed Baba Institute was named.

Hiding the Texts

In addition to the Ahmed Baba Institute, Timbuktu is home to more than 60 private libraries, some with collections containing several thousand manuscripts and others with only a precious handful. (Read about the fall of Timbuktu.)

Sidi Ahmed, a reporter based in Timbuktu who recently fled to the Malian capital Bamako, said Monday that nearly all the libraries, including the world-renowned Mamma Haidara and the Fondo Kati libraries, had secreted their collections before the Islamist forces had taken the city.

"The people here have long memories," he said. "They are used to hiding their manuscripts. They go into the desert and bury them until it is safe."

Though it appears most of the manuscripts are safe, the Islamists' occupation took a heavy toll on Timbuktu.

Women were flogged for not covering their hair or wearing bright colors. Girls were forbidden from attending school, and boys were recruited into the fighters' ranks.

Music was banned. Local imams who dared speak out against the occupiers were barred from speaking in their mosques. In a move reminiscent of the Taliban's destruction of Afghanistan's famous Bamiyan Buddha sculptures, Islamist fighters bulldozed 14 ancient mud-brick mausoleums and cemeteries that held the remains of revered Sufi saints.

A spokesman for the Islamists said it was "un-Islamic" for locals to "worship idols."

Clinton Talks 2016, Stands by Benghazi Testimony

In her final television interview as Secretary of State, Hillary Clinton told ABC's Cynthia McFadden that she is "flattered and honored" at the intense interest in whether she might run for president in 2016.

But Clinton maintained that right now she's "not focused" on a presidential campaign; instead she said she wants to return to a "normal" life when she steps down from office on Friday.

Watch Cynthia McFadden's full interview with Secretary of State Hillary Clinton on "Nightline" tonight at 12:35 a.m. ET

Clinton's first order of business, she said, will be sleep.

"I hope I get to sleep in," she told McFadden with a laugh. "It will be the first time in many years. I have no office to go to, no schedule to keep, no work to do. That will probably last a few days then I will be up and going with my new projects," she said.

"I have been working or attending school full-time since I was 13. This is going to be new for me. I don't know how I'm going to react to it, to be honest."

Clinton has had no trouble articulating her reaction to what has arguably been the darkest chapter of her tenure as Secretary of State: the Sept. 11 attack on the U.S. consulate in Benghazi, Libya, in which four Americans, including Ambassador Chris Stevens, were killed.

Hillary's Next Chapter: On Family and Future Watch Video

Secretary Clinton had a heated exchange with Republican Senator Ron Johnson during her five hours of testimony before Congress about the attack last week. Johnson accused the administration of misleading the American people about the cause of the attack, when UN Ambassador Susan Rice, on Sunday political talk shows, blamed it on protesters.

Clinton snapped back at Johnson, "Four Americans are dead. What difference does it make?" For that, she has been sharply criticized by some conservatives.

Clinton said she "absolutely" stands by her response to Johnson, maintaining that the administration has been transparent with the information it knew, when it was available. Clinton said partisan politics have no place in a response to a terrorist attack against Americans.

"I believe that we should in public life, whether you're in the administration or the Congress, de-politicize crisis and work together to figure out what happened, what we can do to prevent it and then put into place both the institutional changes and the budgetary changes that are necessary, " she said.

"When someone tries to put into a partisan lens, when they focus not on the fact that we have such a terrible event happening with four dead Americans but instead what did somebody say on a Sunday morning talk show? That to me is not in keeping with the seriousness of the issue and the obligation we all have as public servants"

FULL TRANSCRIPT: Sec. of State Hillary Clinton's "Nightline" Interview

Asked about her health, Clinton said her recent illness, concussion and blood clot were all a surprise.

"When I got sick and fainted and hit my head I was so surprised, and I thought I would just get up and go to work. And thankfully I had very good medical care and doctors who said, 'No we'd better do an MRI, we'd better do this, we'd better do that,'" she said, calling herself "lucky."

"I know now how split second beset by a virus and dehydrated, what it can do to you."

Though she confirmed she is wearing special glasses to help with double vision, a lingering issue following her illness, Clinton said that she expects to be fully recovered and operating at "full speed" soon.

The Secretary told McFadden that if she does decide to run, she would have "no problem" making her health records public.

"Of course, that goes with the territory," she said.

Iran launches monkey into space

Lisa Grossman, physical sciences reporter

Last summer, the Iranian Space Agency announced their plan to send a monkey into space - and now they've apparently done it.

According to Iranian state-run television, a press release on the space agency's website, and photos of the event, Iran sent a live rhesus monkey into sub-orbital space aboard a small rocket called Pishgam, or Pioneer. There's even a video posted on YouTube that appears to be of the launch (though New Scientist could not confirm its authenticity).

The report has not been confirmed independently, however, and the US air force's North American Aerospace Defense Command (NORAD) has not reported seeing any missile launches from Iran.

But independent observers say the launch looks legitimate.

"Really, I see no reason not to take their word for it," says Jonathan McDowell, an astronomer at the Harvard-Smithsonian Center for Astrophysics who also keeps a log of space launches. He says he's convinced by the photos and discussions he's had with several knowledgeable source in online forums.

In photos released on the Iranian Space Agency's website, the rocket looks like the same kind the agency has launched before, but with a larger nose cone designed to fit a small chamber that can support life. Images also showed a live rhesus monkey strapped to a small seat.

The reports say the rocket went straight up 120 kilometres, which McDowell says qualifies as outer space, but not high enough to reach orbit, and came back down with a parachute.

It's unclear exactly when the launch took place. The press release says that the launch happened on the birthday of Mohammed the Prophet, which is celebrated by Shiites on 29 January, but was celebrated last week elsewhere in the world.

Some countries worry that Iranian rockets capable of carrying animals or people could also carry weapons. Iran has denied any military intention.

"This is not a scary thing because this is not a big new rocket that could hit America or anything like that," McDowell says. "There's nothing military to this. It's purely for propaganda. Nevertheless, it advances their science and their technology by being able to do it."

Iran says the launch is a first step towards sending humans into space, which they intend to do in the next 5 to 8 years. To do that, McDowell says, they'll need to build a larger rocket. The country currently has a vehicle called Safir that has successfully put satellites in orbit, and is developing a more powerful launcher called Simorgh.

The next step will probably be to either launch Safir to carry a human to sub-orbital space, or an unmanned Simorgh flight into orbit to make sure mission controllers can return it to the ground safely.

"They don't want to repeat what the Soviets did" in 1957, McDowell says, "which is put a living being in orbit before you figure out how to get it back."

North Korea threatens "merciless" retaliation on South

SEOUL: North Korea on Tuesday vowed "merciless" retaliation against the South for its support of UN sanctions, as Seoul urged Pyongyang to step back from a widely expected nuclear test.

The perennially tense situation on the Korean peninsula has been stretched to its limit in the past week, with almost daily threats from the North that it is preparing to conduct a nuclear test as a riposte to the expanded sanctions.

A lengthy commentary published on Tuesday by the official Korean Central News Agency (KCNA) reiterated that the sanctions resolution passed by the UN Security Council was tantamount to a "declaration of war".

Noting what it called the South's "despicable" support for the resolution, KCNA said it was an act of gross provocation that would not go unanswered.

"The provokers will meet only merciless retaliatory blows," it said.

The commentary made no specific mention of the nuclear test that the North's top military body had explicitly signalled in a statement carried by KCNA last week.

The National Defence Commission had said the test was aimed at "arch-enemy" the United States, which had proposed the UN resolution penalising Pyongyang for a banned rocket launch in December.

In Seoul, the foreign ministry on Tuesday noted that the UN resolution had warned of further "significant action" against the North it it proceeds with another test.

"The government once again strongly urges North Korea to pay heed to the continued warnings from the international community and not push ahead with any further provocations, including a nuclear test," spokesman Cho Tai-Young said.

"I don't really understand why North Korea is sticking to an act that threatens security in the region at a time when its people are struggling from a lack of food," Cho said.

South Korean defence officials have said they believe the North is capable of conducting a nuclear test "any time" and announced on Tuesday the creation of a special task force to monitor the site of its two previous tests in 2006 and 2009.

The task force was set up by the South's Joint Chiefs of Staff and is studying data and intelligence being collected by state institutions and independent experts, defence ministry spokesman Kim Min-Seok told reporters.

The state-run Korea Institute of Geoscience and Mineral Resources has set up a situation room to receive and process seismic information that might indicate when a test is conducted, he added.

The institute detected an "artificial earthquake" about 40 seconds after the North's second nuclear test in 2009.

Forget Episode VII, watch 'JJ Abrams Star Wars - The Musical'

Are you a late-model "Star Trek" fan with issues about your guy J.J. Abrams jumping ship in order to direct the next "Star Wars" film? Or maybe a "Star Wars" devotee filled with dread at having your favorite franchise be under the control of someone who's directed two "Star Trek" films?

If so, there's a musical for you. "JJ Abrams Star Wars -- The Musical," to be precise.

Picture Darth Vader and Abrams singing at each other on a pier. Picture Vader shaming Abrams -- well, a very poor look-alike at least -- with a line like, "So you think // you can walk right in // You who joined with the other side // You now betray every 'Star Trek' fan // You have crushed their pride." And then Abrams' rejoinder, "It is true // That I have jumped ship // I was always a Star (Trek) Wars guy // I cannot pass on this perfect chance // Let's see eye to eye."

This is YouTube silliness at its best. It's topical, it's funny (sort of), and it's camp of the highest order. What's not to love?

Abrams, of course, was recently named the director of the "Star Wars Episode VII" after already directing 2009's "Star Trek," and the forthcoming "Star Trek Into Darkness."

Some, of course, wonder whether someone with such a "Star Trek" pedigree can switch sides.

But as our musical's fictional Abrams notes to the incredulous Vader, he will return the "Star Wars" franchise to its glory days, starting with what every real fan's obvious first step: killing off Jar Jar.

Space Pictures This Week: Martian Gas, Cloud Trails

Image courtesy SDO/NASA

The sun is more than meets the eye, and researchers should know. They've equipped telescopes on Earth and in space with instruments that view the sun in at least ten different wavelengths of light, some of which are represented in this collage compiled by NASA and released January 22. (See more pictures of the sun.)

By viewing the different wavelengths of light given off by the sun, researchers can monitor its surface and atmosphere, picking up on activity that can create space weather.

If directed towards Earth, that weather can disrupt satellite communications and electronics—and result in spectacular auroras. (Read an article on solar storms in National Geographic magazine.)

The surface of the sun contains material at about 10,000°F (5,700°C), which gives off yellow-green light. Atoms at 11 million°F (6.3 million°C) gives off ultraviolet light, which scientists use to observe solar flares in the sun's corona. There are even instruments that image wavelengths of light highlighting the sun's magnetic field lines.

US Mom Missing in Turkey Took Side Trips

Sarai Sierra, the New York mother who disappeared in Turkey while on a solo trip, took several side excursions out of the country, but stayed in contact with her family the entire time, a family friend told ABC News.

Turkish media reported today that police were trying to establish why Sierra visited Amsterdam and Munich. Police were also trying to establish the identity of a man Sierra, 33, was chatting with on the Internet, according to local media.

Rachel Norman, a family friend, said the man was a group tour guide from the Netherlands and said Sierra stayed in regular touch with her family in New York.

Steven Sierra, Sarai's husband, and David Jimenez, her brother, arrived in Istanbul today to aid in the search.

The men have been in contact with officials from the U.S. consulate in the country and plan to meet with them as soon as they open on Tuesday, Norman said.

After that, she said Sierra and Jimenez would meet with Turkish officials to discuss plans and search efforts.

Sarai Sierra was supposed to fly back to the United States on Jan. 22, but she never showed up for her flight home.

Her two boys, ages 11 and 9, have not been told their mother is missing.

Sierra, an avid photographer, left New York on Jan. 7. It was her first overseas trip, and she decided to go ahead after a friend had to cancel, her family said.

"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.

But when it came time to pick her up from Newark Liberty International Airport in New Jersey, Sierra wasn't on board her scheduled flight.

Steven Sierra called United Airlines and was told his wife had never boarded the flight home.

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

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

The U.S. Embassy in Turkey and the Turkish National Police are involved in the investigation, WABC-TV reported.

"They've been keeping us posted, from my understanding they've been looking into hospitals and sending out word to police stations over there," Steven Sierra said. "Maybe she's, you know, locked up, so they are doing what they can."

Is Obama about to blow his climate credentials?

The US president could be poised to approve the doubling of imports of tar sands oil, one of the filthiest fuels on Earth

FACED with rising anger from environmentalists last year over his plans for a transcontinental pipeline to deliver treacly Canadian tar sands to Texas oil refineries on the Gulf of Mexico, the CEO of TransCanada, Russ Girling, expressed surprise. After all, his company had laid 300,000 kilometres of such pipes across North America. "The pipeline is routine. Something we do every day," he told Canadian journalists.

But that's the point. It is routine. The oil industry does do it every day. And if it carries on, it will wreck the world.

We need not rely on climate-changing fossil fuels. Alternative energy technologies are available. But fossil fuels, and the pipelines and other 20th-century infrastructure that underpin them, have created what John Schellnhuber, director of Germany's Potsdam Institute for Climate Impact Research, describes in a new paper as "lock-in dominance" (PNAS, DOI: 10.1073/pnas.1219791110). Even though we know how harmful it is, the "largest business on Earth" has ossified and is proving immovable, he says.

The question is how to break the lock and let in alternatives. Schellnhuber, a wily and worldly climate scientist, has an idea, to which I will return. But first the tar-sands pipeline, known as Keystone XL in the parlance of outsize clothing. Proponents say it would create jobs and improve US energy security. But for environmentalists in the US, the decision - due any time - on whether it should go ahead is a touchstone for Barack Obama's willingness to confront climate change in his second term.

Superficially, Keystone XL doesn't look like a huge deal. Since 2010, there has been a cross-border pipe bringing oil from tar sands in northern Alberta to the US Midwest. But this second link would double capacity and deliver oil to the refineries of the Gulf for global export. It looks like the key to a planned doubling of output from one of the world's largest deposits of one of the world's dirtiest fuels. And because the pipe would cross the US border, it requires state department and presidential sign-off.

Environmentalists are up in arms. They fear leaks. No matter what its sponsors suggest, this is no ordinary pipeline. The tar-sands oil - essentially diluted bitumen - is more acidic than regular oil and contains more sediment and moves at higher pressures. Critics say it risks corroding and grinding away the insides of the pipes. The US National Academy of Sciences has just begun a study on this, but its findings will probably be too late to influence Obama.

If there is a leak, clean-up will be difficult, as shown by the messy, protracted and acrimonious attempt to cleanse the Kalamazoo river in Michigan after tar-sands oil oozed into it in 2010.

To make matters worse, the pipeline would cross almost the entire length of the Ogallala aquifer, one of the world's largest underground water reserves, from South Dakota to Texas. Ogallala is a lifeline for the dust-bowl states of the Midwest. While TransCanada has agreed to bypass the ecologically important Sand Hills of Nebraska, where the water table is only 6 metres below the surface in places, a big unseen spill could still be disastrous.

Climate change is still the biggest deal. Extracting and processing tar sands creates a carbon footprint three times that of conventional crude. Obama would rightly lose all environmental credibility if he were to approve a scheme to double his country's imports of this fossil-fuel basket case. Yet he may do it. Why? Because of fossil-fuel lock-in. Changing course is hard. Really hard.

Part of the reason for the lock-in is the vast infrastructure dedicated to sustaining the supply of coal, oil and gas. There is no better symbol of that than a new pipeline. Partly it is political. Nobody has more political muscle than the fossil fuel industry, especially in Washington. And partly it is commercial. As Schellnhuber puts it: "Heavy investments in fossil fuels have led to big profits for shareholders, which in turn leads to greater investments in technologies that have proven to be profitable."

The result is domination by an outdated energy system that stifles alternatives. The potential for a renewable energy revolution is often compared to that of the IT revolution 30 years ago. But IT had little to fight except armies of clerks. Schellnhuber compares this lock-in to the synapses of an ageing human brain so exposed to repetitious thought that it "becomes addicted to specific observations and impressions to the exclusion of alternatives". Or, as Girling puts it, new pipelines become "routine".

What might free us from this addiction? With politicians weak, an obvious answer is to hold companies more financially accountable for environmental damage, including climate change. But Schellnhuber says this won't be enough unless individual shareholders become personally liable, too.

Here, he says, the problem is the public limited company (PLC), or publicly traded company in the US, which insulates shareholders from the consequences of decisions taken in their name. Even if their company goes bankrupt with huge debts, all they lose is the value of their shares. The PLC was invented to promote risk-taking in business. But it can also be an environmental menace, massively reducing incentives for industries to clean up their acts.

"If shareholders were held liable," he says, "then next time they might consider the risk before investing or reinvesting." More importantly, it could prevent us being locked into 20th century technologies that are quite incapable of solving 21st century problems. Fat chance, many might say. But just maybe Keystone XL and its uncanny ability to draw global attention will help catalyse growing anger at the environmental immunity of corporate shareholders.

EU calls for more entrepreneurs

BRUSSELS: Policy makers in Europe want to convince more people to become entrepreneurs in order to bring back jobs and growth to the struggling bloc.

Critics have argued too many start-ups in a volatile financial climate will only struggle to survive while others said business-minded self-starters are born, not bred.

Policy makers in Brussels are more and more adamant that self-made businessmen and women will become the job creators Europe desperately needs.

The EU wants more entrepreneurial training at schools and universities, tax reductions for small businesses and the revision of insolvency rules countries so that honest failures don't inhibit entrepreneurs from trying again.

EU commissioner for enterprise, Mr Antonio Tajani, said: "We focus on entrepreneurs because entrepreneurs are innovative and they are the ones who come up with ideas. Even small entrepreneurs create jobs and growth over the last few years."

Traditionally, Europeans have been reluctant entrepreneurs. Last year, only 37 per cent of citizens were willing to launch their own business compared to levels of over 50 per cent of people in the US, China and Brazil.

Oliver Witmeur, from the Solvay Business School Entrepreneurship Academy said: "In the US and UK, entrepreneurship is positive. In Europe, we are more complicated. We don't like failure and success."

At the Solvay business school in Brussels, the Entrepreneurship academy has been running for thirty years. Despite the crisis and thanks to the growing role of technology, more and more students are singing up to the course.

Many point to Europe's complicated and inflexible labour laws as a key obstacle to more jobs and growth. However, there are voices who argue that more startups may be enough to jumpstart Europe's recovery.

Mr Witmeur said: "If you look at the big firms, the number of jobs is more or less decreasing. If you take the very small firms, there is same number of people coming in and exit. But the real growth drivers are growth in small number of companies in what we call the "gazelle" and they are creating new jobs"

Europe's unemployment crisis will force many into entrepreneurship out of necessity.

On the positive side, it may mean many out of a job will decide to pursue a life-long business idea, in hope that the EU's new action plan will inject some inspiration and make it easier for them.

LAS VEGAS--Alec Saunders needed a little bait.

Soon after Saunders took over the developer relations team, he asked Research In Motion's then co-CEO Mike Lazaridis in October 2011 for 25,000 BlackBerry PlayBook
tablets. When Lazaridis asked why, Saunders said he intended to give them away.

"His jaw just dropped to the floor," Saunders told CNET. "He stood there flabbergasted."

Lazaridis ultimately agreed, and Saunders began giving PlayBooks out to developers. He followed that up by giving away more than 8,000 units of RIM's Dev Alpha devices, which ran an early version of BlackBerry 10.

Saunders knew he needed to get the long-ignored BlackBerry developer base excited again. In 48 out of the last 52 weeks, he has been on a plane circling the globe in an effort to drum up interest in every corner. Combine the mileage he and his team of nearly 100 evangelists have logged for RIM, and there would be enough to travel to the moon and back five times over, or 2.5 million miles.

"I took December off and took the time to get to know my wife," he quipped.

Saunders has embraced a concept that RIM had long ignored: that developers and a healthy app "ecosystem" can make or break an operating system. He's tried to make it more accommodating and responsive to developers. It's the touchy feely stuff RIM execs never thought was important.

"Development sentiment is crucial," he said. "Developer interest is a leading indicator of success for any platform."

There's a lot riding on BlackBerry 10, which after a series of delays is expected to be unveiled on Wednesday in New York. Having had no significant new product in more than a year, RIM needs a hit. Badly. Simply put, the BlackBerry operating system is in free fall. In the third quarter, the BlackBerry OS accounted for 5.3 percent of the market, a tick above Samsung Electronics' homegrown Bada OS (little more than a glorified experiment for the Korean handset giant), and less than half the 11 percent share it held a year ago, according to a Gartner study. In the same period,
Android's market share surged to 72.4 percent from 52.5 percent a year ago.

Now RIM has has to win back consumers who have long abandoned their BlackBerrys for iPhones and Android devices. It's planning a media blitz, complete with Super Bowl commercial. At the same time, BlackBerry has to compete against another upstart mobile operating system, Windows Phone by Microsoft, which is also seeking to be the No. 3 platform behind Google's Android and Apple's iOS.

Indeed, RIM has a long, tough road ahead of it, but credit Saunders for connecting with the developer community. When the operating system is unveiled, it will have 70,000 applications, which the company boasts is the most apps for a mobile platform at launch. Android had a little more than 50 apps at launch, but that was before the explosion of app development.

"I can't describe what (Saunders) achieved in one and a half years," CEO Thorsten Heins said in a recent interview. "I can't speak highly enough of him."

Of course, RIM will be going up against two ecosystems with an entrenched following. Apple, for instance, boasts of more than three-quarters of a million apps for iOS, while Android has more than 700,000 apps in the market. The Windows Phone Store has 125,000 apps, having doubled in size after the launch of Windows Phone 8 late last year.

Fresh start

I sat with Saunders earlier this month at the Consumer Electronics Show to talk about his efforts to convince skeptical developers to give BlackBerry another chance. I had arranged to meet with with him in the Rojo lounge of the Palms Place hotel, an extension of the Palms Casino Resort.

Rojo is a small, dark, and smoke-filled bar awash in red-neon accent lighting. A downed air-conditioning system meant a stiflingly hot environment, despite the windy and cold weather outside. It looked like hell, and that night, it felt like it too.

When I finally met up with Saunders and his entourage, which included a few public relations representatives and another developer evangelist, Tom Anderson, the heat in the bar forced us out to the minimalist and slate-dominated lobby for our sit-down chat.

Saunders wore a black suit jacket, button-down shirt, and blue jeans, and had just come in from a flight from Ottawa, Canada.

Saunders, a family man who leads a scout troop in his off hours, can't help but to come off as a nice, normal guy. He spoke in a calm and even tone with a slight Canadian accent. But his jovial and seemingly laid-back manner gave way to enthusiasm when talking about RIM's developer efforts.

"We're building a good head of steam behind us," he said. "Good things are happening."

Saunders had roots at RIM even before he joined the company in June 2011. He had previously worked at QNX before leaving to run his own start-up, a Web conferencing provider called iotum. QNX was eventually bought by RIM in April 2010, and its software forms the foundation for BlackBerry 10.

So it was a homecoming of sorts for Saunders when he joined RIM, right about when its market share started to collapse.

"It seemed like a good challenge to me," he said.

He made it clear he was a different sort of RIM exec. At one of his first public outings as vice president of developer relations, Saunders made the highly unusual move of posting his e-mail address while on stage at one of the company's many developer conferences.

"That was huge," said Jeremy Wall, a part-time BlackBerry developer who was in attendance at that conference and dabbled with the platform for the past decade. He, like everyone else in attendance, immediately grabbed his phone to update his contact list.

The result: a flood of e-mail that occupies a good chunk of Saunders' time. He received 14,793 e-mails -- in the last quarter alone. More recently, he's also taken to Twitter to answer questions, where he tweets under the user name @asaunders.

"My wife wasn't too happy with me," he joked during an interview with CNET shortly after that conference.

Fixing a broken system

The old RIM wasn't exactly friendly to developers. From complications signing up to fragmentation in the different versions of the BlackBerry operating system, creating an app for the platform could be a nightmare. One developer politely called it "rough," and said the company previously had the tendency to drop or ignore questions or concerns.

At the same time, iOS was beginning to generate interest from app developers. RIM executives, meanwhile, clung to the idea that e-mail and security were more important to users.

"Sometimes a good (butt)-whoopin' is what you need," said Michael Nowlin, who works for a cable set-top box manufacturing company but is an enthusiast and part-time developer known as "BlackBerry Hank."

"We're building a good head of steam behind us. Good things are happening.""

When Saunders joined, he knew RIM had big problems. So he made his pitch to the most loyal BlackBerry developers first before expanding to a broader audience.

Saunders laid out a model of responsiveness for which developers have expressed appreciation. When Wall, a part-time developer who also works at a manufacturer of weather stations, was setting up a local meet-up between BlackBerry developers and a RIM executive, he had hit a wall with the usual company contacts. When he e-mailed Saunders, he got a response back in 10 minutes and had an executive on his way to the meetup.

"I'll sing the praises of Alec Saunders all day for that," Wall said.

That new-found enthusiasm also attracted Nowlin, who is a relative newcomer to the BlackBerry ecosystem. He hopped on the bandwagon after seeing the kinds of tools and support available to him during a developer conference in June.

He likewise praised Saunders for his responsiveness and willingness to listen.

"He made me feel like he really cared, and he showed it," said Nowlin, a San Antonio native who works support for a set-top box manufacturer and develops BlackBerry 10 apps on the side.

While relations between developers and RIM improved, it was largely moot. With the older BlackBerry platform showing its age and the company moving to an unproven next-generation operating system, developers weren't too keen to take a chance, especially with the exploding potential coming from iOS and Android.

It was Saunders' idea of the PlayBook giveaway that got developers taking a more serious looking at RIM again.

Looking back, the PlayBook was ultimately more valuable as a relationship-building tool than a product. The much-hyped tablet launched in early 2011 with a thud, with only modest sales coming after heavy discounts and several software updates. To be fair, the PlayBook continues to sell, and the company shipped 255,000 units in the last reported quarter.

Early in the giveaway, RIM wasn't terribly choosy when handing over the PlayBooks -- a move Saunders said bought a lot of goodwill. But more recently, the company raised its standards and sought out developers with a genuine interest in the platform. At the last SXSW conference, developers were pitching RIM execs with half-finished apps before they were rewarded with a PlayBook to complete their work.

"RIM has done an astonishing job of getting developers to back a company which many people have completely written off," said Avi Greengart, an analyst at Current Analysis.

Time and money

While both the iOS and Android platforms can boast of massive user bases, RIM could only point to the PlayBook, a few thousand developer units and some fleeting glimpses of actual BlackBerry 10 products, which have faced multiple, frustrating delays.

As a result, there are still legions of developers who still veer away from RIM, considering it a risky bet next to the larger platforms. According to a June report by market analytic firm VisionMobile, the BlackBerry platform (old and new) is "very close to becoming an endangered species," with 41 percent of developers surveyed saying they were dumping the platform.

So Saunders and his team have shifted the conversation to address two other key concerns for developers: time and money.

RIM promised a much easier development process with BlackBerry 10. Regardless of the code or platform, it could easily be moved over to BlackBerry.

"Bring your code, and we'll find a way to make it happen," Saunders said.

RIM evangelist Anderson said he had gotten use to getting greeted with looks of skepticism when he went to talk to developers about BlackBerry. Now, he said he can turn them around after just a few minutes by showing them the simplified process of development and porting.

Equally important was the potential monetary return on a BlackBerry app. RIM executives told developers at a conference in May that it would guarantee that an app would generate $10,000 in revenue in their first year, or the company would make up the difference. (The fine print is that the app would have to be certified and generate at least $1,000 from downloads).

RIM has argued that its platform is a deceptively lucrative place for developers -- if you exercise a little math. If you remove the top 5 percent of highest-grossing apps, then BlackBerry's platform actually generates the most revenue, Saunders said. So for little-known developers without big brands, BlackBerry may prove to be a better home, he argued.

While fairly negative on BlackBerry's prospects, the VisionMobile report did note that a BlackBerry developer made an average of nearly $4,000 a month, or 4 percent better than the next best performing platform, iOS.

"The developer community that's behind them now is organic. They built it."

Beyond those factors, Saunders and his team has tried to directly talk to as many developers as possible. Since June, it has held 44 developer-focused BlackBerry Jam World Tour events and 11 Enterprise Jam events in more than 40 countries, hosting a total of nearly 10,000 developers. In addition to the launch on Wednesday, Saunders is preparing for BlackBerry Jam Europe next week.

There's little choice: These developers are essentially working on blind faith, with no actual products to work from and no proof that consumers will even buy them. Saunders and his team has had to apply a personal touch.

At least among its hardcore devotees, it's working.

"The developer community that's behind them now is organic," said George McKinney, an independent app developer based in Los Angeles. "They built it."

McKinney, who employs three people in a small development shop, primarily does work on iOS and Android apps, but said he works on BlackBerry 10 apps "because we have a lot of fun with it."

Singing a different tune

Saunders and fellow executives Chris Smith, vice president of application platform & tools, and Martyn Mallick, vice president of global alliances and business, were certainly having fun when they shot a music video set to REO Speedwagon's "Keep on Loving You."

When it was released on YouTube, the video -- and RIM -- became the target of ridicule from the press, who called it "awful" and feared it was a desperate and awkward attempt to woo developers.

Saunders' eyes lit up when I asked him about it, and it was clearly a labor of love. He said the developers enjoyed the video, and were captivated when it aired during its conferences. He said it was an attempt to break away from the usual "stupid energy clip" that precedes speeches and demos.

"We had a lot of fun with it," he said, teasing that one more music video was in the works.

Less light-heartedly, in the past few weeks, RIM has started to contact developers through e-mails and blog posts, pushing them to step up and get their apps ready in time for the launch this week.

In a last-minute scramble, Saunders earlier this month helped run an online "Portathon" that netted the submission of 15,000 apps for BlackBerry 10 after more than a day and a half.

"Well, there you have it...Feel like I've run a marathon," Saunders tweeted after the event.

For Saunders and the rest of RIM, the marathon to get the company back on track has just begun.
