Hollande gets hero's welcome in a Mali fearful of future






BAMAKO: President Francois Hollande received a rapturous welcome in Mali on Saturday as he promised that France would stay as long as necessary to continue the fight against Islamist rebels in the country's north.

As troops worked to secure Kidal, the last bastion of radicals who occupied the vast desert north for 10 months before the French army's surprise intervention, Hollande told Malians it was time for Africans to take the lead but that France would not abandon them.

"Terrorism has been pushed back, it has been chased away, but it has not been defeated yet," said Hollande, whose decision to intervene in Mali three weeks ago won him accolades in the former French colony.

"France will stay by your side as long as necessary, as long as it takes for Africans themselves... to replace us," he told a large crowd in the capital, Bamako, at a monument commemorating Mali's independence from France.

Earlier, in the fabled city of Timbuktu, thousands gathered in the central square and danced to the beat of drums -- a forbidden activity during the extremists' occupation -- to welcome the French leader, with shouts of "Vive la France! Long Live Hollande!"

Mali's interim president Dioncounda Traore thanked his counterpart for the French troops' "efficiency", which he said had allowed the north to be freed from "barbarity and obscurantism".

Hollande was offered a young camel draped in a French flag as he toured the city.

"The women of Timbuktu will thank Francois Hollande forever," said 53-year-old Fanta Diarra Toure.

"We must tell him that he has cut down the tree but still has to tear up its roots."

Hollande and Traore toured Timbuktu's 700-year-old mud mosque of Djingareyber and the Ahmed Baba library for ancient manuscripts.

As they visited the site of two ancient saints' tombs that the extremists tore down with pickaxes in July, considering them idolatrous, Hollande told the mosque's imam: "There's a real desire to annihilate. There's nothing left."

"We're going to rebuild them, Mr President," said Irina Bokova, the head of UNESCO, which is trying to assess the scale of the damage to Mali's ancient heritage -- particularly in Timbuktu, a caravan town at the edge of the Sahara that rose to fame in the 14th century as a gold and salt trading hub.

After Hollande's visit, Mali's national football team pulled off a win against Africa Cup of Nations hosts South Africa to go through to the continental championship semi-final, their best performance since 1972 and another welcome boost to national pride amid the crisis.

Traore congratulated the team on national television, and jubilant crowds took to the streets in Bamako despite a state of emergency in place since January 12.

"This victory... is going to help Mali find peace again," said Mamadou Traore in the capital's Same neighbourhood as his children jumped with excitement.

Reprisal attacks

With the rebels ousted from all major towns but Kidal in the northeast, France is keen to hand over to nearly 8,000 African troops slowly being deployed, which the United Nations is considering turning into a formal UN peacekeeping force.

But there are warnings Mali will need long-term help and fears the Islamists will now wage a guerrilla campaign from the sparsely populated north.

The joy of citizens throwing off the yoke of brutal Islamist rule, under which they were denied music and television and threatened with whipping, amputation of limbs and even execution, has been accompanied by a grim backlash against light-skinned citizens seen as supporters of the extremists.

Rights groups have reported summary executions by both the Malian army and the Islamists.

Human Rights Watch said Friday that Malian troops had shot at least 13 suspected Islamist supporters in Sevare and dumped them into wells.

Mali's military was routed at the hands of rebel groups in the north, whose members are mostly light-skinned Tuaregs and Arabs, before the French army came to its aid.

With fears of reprisal attacks high, many Arabs and Tuaregs have fled.

In all, the crisis has caused some 377,000 people to flee their homes, including 150,000 who have sought refuge across Mali's borders, according to the United Nations.

Hollande called on all troops in Mali to show "exemplary" conduct and respect human rights -- an appeal echoed interim president Traore, who promised to lead a national reconciliation process and repeated that he wants to hold elections by July 31.

The French-led intervention has met little resistance, with many of the Islamists believed to have slipped into the desert hills around Kidal -- likely taking seven French hostages with them, officials say.

While largely supported by the French public, the operation has not yet paid domestic political dividends for Hollande, failing to reverse a steep slide in his approval ratings as the economy struggles.

US Vice President Joe Biden praised the French intervention Saturday.

"That's why the United States applauds and stands with France and other partners in Mali, and why we are providing intelligence support, transportation for the French and African troops and refuelling capability for French aircraft," he told top military brass at a security conference in Munich.

Apple updates Java for Snow Leopard following blockage



Following another recent security issue with Java, Apple issued an update that added the latest versions to the system's browser plug-in blacklist to protect users from any potential threats; however, in doing so it silently blocked a number of people from accessing required Java content, such as banking and financial Web sites.


To manage this problem, if you need Java, then the latest version from Oracle (version 1.7.0_13) that was released yesterday should have addressed the security holes and get your system back up and running. You can download it for OS X Lion or Mountain Lion from Oracle at its Java Downloads page.


Unfortunately the Java 7 runtime is not available for those using
Snow Leopard, for which the latest version is Java 6. However, Apple has issued its own separate update to Java 6 for Snow Leopard to address the vulnerabilities in this version. The update, which should be available through its Software Update service, should run automatically or can be invoked by going to the Apple menu.


Given the stream of recent security issues with Java, if you don't need Java, then you might consider avoiding using it on your system, or at least be sure to disable the Web plug-in for it. While Java is a powerful and useful runtime that a number of programs use, the avenue for exploiting it is almost exclusively through the Web plug-in component of the runtime, so if you find you do need it installed, then you might at least consider disabling the plug-in in the Java Control Panel (or in Apple's Java Preferences utility for Java SE 6).

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

Body of Missing Mom Reportedly Found in Turkey













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


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


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


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


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

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


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


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


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


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


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


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

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 atmosphereMovie Camera.













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.

Football: Fergie surprised by Beckham's PSG move






LONDON: Alex Ferguson admits he was surprised to see his former Manchester United star David Beckham sign for Paris St Germain.

Beckham had been looking for a new club since leaving LA Galaxy in November and snubbed interest from several Premier League clubs and other lucrative offers from around the world to join the French outfit on transfer deadline day.

Ferguson didn't think Beckham would come back to the Premier League as the boyhood United fan had previously said he could never play for another English club.

But the United manager was still shocked to see the 37-year-old former England captain unveiled by PSG on Thursday.

"I was surprised. I didn't see that," Ferguson told MUTV. "I didn't think he would join an English club.

"He always said he wouldn't after his career with United and he was true to his word. But I don't think anyone saw PSG coming."

While Beckham completed his high-profile move, English football was engaged in a typically frenzied finish to the January transfer window and Ferguson had no intention of being drawn into the mad scramble for new players.

"It is an absolute shambles," he said.

Referring to television coverage of the final hours of the window, which features reporters standing outside the training grounds and stadiums of all Premier League clubs, Ferguson said: "There is a young reporter being mobbed by 30 kids. It is humiliation. I am sure all the managers are glad it is all over."

NFL Looks to Helmet Technology to Combat Concussions


When the Baltimore Ravens and San Francisco 49ers face off at Super Bowl XLVII this weekend, they'll also be facing a common foe: the threat of concussion.

It's why Sunday's game will include cameras in the media box devoted to helping team trainers and physicians spot unusual behavior in players that suggests they may have suffered a head injury. (See a graphic of recorded head impacts suffered by one player over a season.)

"Imagine how controversial this would have been before," said Richard Ellenbogen, co-chairman of the NFL's Head, Neck, and Spine Committee, referring to the camera scheme. "The opposing team would have thought the other team was looking at their plays—but now the film is purely for safety."

Players' willingness to suffer those cameras is a sign of just how concerned they've become about head injuries in recent years.

Just last week, the NFL and helmet manufacturer Riddell were named in a lawsuit filed by the family of retired linebacker Junior Seau, who killed himself last year. Posthumous tests revealed that Seau had chronic traumatic encephalopathy (CTE), a brain disease linked to repetitive head blows.

Seau's family alleged that his suicide resulted from CTE, which can cause neurobehavioral problems like depression.

Several thousand former NFL players and family members have already sued the NFL over head injuries. As the litigation mounts, the sports world's focus on concussions, from the youth to professional levels, has quickened the pace of related research and education on the issue.

The effort has produced scientific studies, rule changes in football and other sports, and research investments, like the $100 million grant awarded this week by the NFL Players Association to Harvard Medical School for a ten-year study of players' health.

And on Sunday, an NFL announcement is expected on a big partnership on one of the concussion war's key fronts: helmet technology.

Testing on the Gridiron

At labs in Ottawa, Canada, and outside Knoxville, Tennessee, the push to monitor hits that can cause concussions is on dramatic display: Football helmets sit on dummy heads while a piece of machinery slams into them at a set speed.

Sensors in three places—the helmet, mouthpiece, and center of the head form—measure acceleration and G forces from the impact. The goal: to ensure the sensors in the helmet and mouthpiece come up with accurate measurements.

The NFL commissioned the nearly yearlong study as a possible step toward fitting players with sensors that would flag dangerous hits in real time.

Kevin Guskiewicz, chair of the NFL subcommittee on safety equipment and playing rules, says the tests cover 12 helmet locations at five different velocities to simulate the conditions of player impacts during football games. He expects results on those tests soon.

The need is clear: More than 200 concussions have been reported in each of the last three NFL seasons, according to Ellenbogen. Last year's count—excluding postseason and including preseason—was 217.

Guskiewicz, director of the University of North Carolina Sports Concussion Research Program, has already collected data on on some 350,000 impacts sustained by football players on the college team.

For nine seasons, he has analyzed the data in hopes of cracking what he calls the concussion puzzle. The biggest hits aren't always the most damaging, he discovered; location and repetition matter too.

"Helmets are supposed to prevent catastrophic brain injury, like hemorrhages," said Guskiewicz. "They do a good job of that, but we want a helmet that does that as well as prevent concussion."

Building Better Helmets

In seeking that kind of hlmet, the NFL has sought help from the U.S. military, which has long studied head safety, since soldiers can suffer from brain injuries caused by head-rattling blasts.

A couple of years ago, the NFL and other sports leagues gathered in New York with members of the Defense Advanced Research Projects Agency (DARPA) to discuss protective technology. The exchange of information between the NFL and the military continues to this day.

Accurate sensors that measure impacts in real time would be a big advancement in head-trauma protection, said Lt. Col. Frank Lozano, the U.S. Army's product manager for soldier protective equipment.

Already the Army has tens of thousands of sensors placed in the crown of certain soldiers' helmets to measure the forces exerted on their heads. "It comes down to understanding the transfer of energy through a helmet and into the head," Lozano said.

Concussion occurs when the brain is injured from shaking or slamming against the skull. The more a helmet can absorb the force of an impact, the less the brain absorbs.

Pads lining the inside of the helmet are vital to absorbing the shock. They can vary in material, stiffness, and thickness. Lozano noted that the Army looks every year at pad suspension systems in search of ways to improve their helmets.

The Army is also studying potentially new materials for making helmet shells. One special type of thermoplastic being studied, Lozano said, is many times stronger than steel but a fraction of the weight.

Driving Toward Progress

Combatting concussion isn't limited to football—or to the United States.

The NFL committee's Ellenbogen noted that he recently met with representatives from Australian rugby, British equestrians, and European soccer, who are actively trying to make their sports more concussion-proof.

At a concussion conference in Zurich last year, he said, officials from soccer's international ruling body, FIFA, were fascinated with the idea of using cameras in the media box to focus on players from different angles and help athletic trainers spot anything unusual.

The video can also be fed to team physicians on the field, who will be carrying iPads for the first time at a Super Bowl. The device allows them to record and time players' responses to a sideline concussion test covering areas like memory, concentration, and balance.

Symptoms such as disorientation, amnesia, and double vision require disqualification; others are subtler, like the time it takes to recall words and facts such as who scored last.

"There's no perfect test," said Ellenbogen. But he cited good doctors, better communication, technology, awareness, and more penalties for unnecessary roughness as positive advances in the field.

Hillary Clinton Says Goodbye...Until 2016?


Feb 1, 2013 6:48pm







ap hillary clinton mi 130201 wblog Hillary Clinton Says Goodbye ... Until 2016?

After four years, nearly a million miles traveled and 112 countries visited, Hillary Clinton stepped down as the 67th secretary of state on Friday. But even on this, her final day as America’s top diplomat, she could not escape the questions about what she’ll do four years from now.


Many of the 1,000 employees who gathered to see her off expressed hope that this was not the end of her political career.


“2016! 2016!” the crowd chanted as   Clinton waved and drove away. “We’ll Miss You!”


Right before her departure, Clinton gave the traditional farewell speech to staff on the steps of the State Department’s historic C street lobby. In a roughly 10 minute, often reflective speech she called the 70,000 State Department employees part of “a huge extended family.”


“I cannot fully express how grateful I am to those with whom I have spent many hours here in Washington, around the world and in airplanes,” she said, drawing laughter from the audience.


Clinton’s trademark sense of humor was on display, even as she grew emotional  speaking about how much the State Department had  meant to her over the last four years.

“I am very proud to have been secretary of state. I will miss you. I will probably be dialing ops just to talk,” she joked to a cheering and laughing crowd. “I will wonder what you all are doing, because I know that because of your efforts day after day, we are making a real difference.”


But  Clinton also was somber when discussing the danger diplomats and foreign service officers face all over the world, using Thursday’s suicide bombing attack against the U.S. Embassy in Ankara, Turkey, in which a Turkish guard was killed, as an example.


“We live in very complex and even dangerous times, as we saw again just today at our embassy in Ankara, where we were attacked and lost one of our foreign service nationals, and others injured,” said Clinton “But I spoke with the ambassador and the team there. I spoke with my Turkish counterpart. And I told them how much we valued their commitment and their sacrifice.”


Clinton was flanked by trusted deputies, Bill Burns and Tom Nides, whom she gave warm hugs to at the end of the speech. With a huge “Thank You” sign behind her she walked a rope line after finishing her speech, greeting the hordes of employees who wanted to shake her hand and say goodbye before she walked out of the State Department as secretary of state for the last time.


“It’s been quite a challenging week saying goodbye to so many people and knowing that I will not have the opportunity to continue being part of this amazing team,” Clinton said. “But I am so grateful that we’ve had a chance to contribute in each of our ways to making our country and our world stronger, safer, fairer and better.”

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.
