Two worms, same brains – but one eats the other



































IF TWO animals have identical brain cells, how different can they really be? Extremely. Two worm species have exactly the same set of neurons, but extensive rewiring allows them to lead completely different lives.












Ralf Sommer of the Max Planck Institute for Developmental Biology in Tübingen, Germany, and colleagues compared Caenorhabditis elegans, which eats bacteria, with Pristionchus pacificus, which hunts other worms. Both have a cluster of 20 neurons to control their foregut.












Sommer found that the clusters were identical. "These species are separated by 200 to 300 million years, but have the same cells," he says. P. pacificus, however, has denser connections than C. elegans, with neural signals passing through many more cells before reaching the muscles (Cell, doi.org/kbh). This suggests that P. pacificus is performing more complex motor functions, says Detlev Arendt of the European Molecular Biology Laboratory in Heidelberg, Germany.












Arendt thinks predators were the first animals to evolve complex brains, to find and catch moving prey. He suggests their brains had flexible wiring, enabling them to swap from plant-eating to hunting.

Psy to perform at Malaysia ruling coalition party






KUALA LUMPUR: South Korea's Psy will perform his famous "Gangnam Style" dance at an event organised by Malaysia's ruling coalition, an official said Sunday as the bloc tries to attract young voters ahead of polls.

Psy will perform the hit, which made history as the most-watched video on YouTube, at a Chinese New Year party on the northern island of Penang on February 11, said Loh Hock Hun from the Malaysian Chinese Association (MCA).

The organisers hope to attract some 60,000 people including Prime Minister Najib Razak, Loh said. He could not say how much the concert, to be staged by the Barisan Nasional coalition of which the MCA is part, would cost.

Some 25 percent of Malaysia's 29 million people are ethnic Chinese and celebrate the lunar new year.

Najib, who must face tough elections by June at the latest, hopes to improve on his coalition's worst ever poll performance in 2008. Those aged below 40 make up 40 percent of the electorate.

In 2008, the coalition lost its traditional two-thirds parliament majority and control over five states including Penang, to a resurgent opposition amid voter complaints that Barisan Nasional leaders seemed too aloof and corrupt.

South Korean pop music is popular in Malaysia with a recent show, the annual Golden Disk Awards featuring performances by Super Junior and other acts, drawing thousands of fans.

Psy, who is slated to perform in Brazil's carnival celebrations next week, is also expected to take the stage in Malaysia in March for a music show at the Sepang International Circuit racetrack.

Psy made Internet history last December when "Gangnam Style" -- featuring his signature horse-riding dance -- clocked more than one billion views on YouTube.

How Boeing's 777-300ER could help save American Airlines



American Airlines hopes its rise back to profitability and relevance can get a big jump start with the launch of all-new livery, and Boeing's 777-300ER. It is the first U.S. carrier to fly the plane, the most successful twin-engine aircraft in the world.

It has become the world's most-successful twin-engine airplane, but until now, no U.S. carrier has flown Boeing's 777-300ER. But with the launch on Thursday of its Dallas to Sao Paolo, Brazil flight, American Airlines has broken new ground, and is now depending on its fledgling 777-300ER fleet to re-earn its once legendary wings. And make it a lot of money.



Among the many passengers aboard the inaugural flight to Sao Paolo was Chris Sloan, an aviation writer who often flies on the most notable planes in the skies. Sloan, who previously shared his impressions of the inaugural Boeing 787 Dreamliner commercial flight with CNET, has once again let us in on what it's like to be among the first people aboard a notable, world-class airplane.




As Sloan notes, the past few years have not been kind to American Airlines. The carrier has gone through bankruptcy, seats becoming unbolted, a disastrous crash, and more.


But the airline is doing its best to come back from the dead, and the launch of service aboard the 777-300ER, as well as the roll-out of all-new livery, show that American can't be counted out.


As Sloan wrote:

In an era of smaller airliners, American inaugurated the 777-300, the largest new airliner by a U.S. carrier since the last Boeing 747-400s entered service with U.S. airliners in the late 1990s. Built to handle up to 386 passengers and fly up to 7,825 nautical miles, American's 777-300ER is the first plane flown by a U.S. carrier to feature a stand-up bar since the 1970s, Sloan wrote. American flies the aircraft in a 304-passenger, four-class and six-cabin configuration.


This inaugural, flight 963, from Dallas/Ft. Worth to São Paulo, Brazil in the author's view is one of the most significant in the airline industry in years because it is about something much bigger than just the launch of a new airliner, it's about the re-birth of a proud American institution that happens to bear the name of our country - American Airlines.

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.)

Gun Violence 'Depletes Precious Natural Resource'












It took the mass shooting in Newtown, Connecticut, to prompt lawmakers to call for stricter gun legislation. But the reality is that in a city like Chicago, where 515 murders took place last year and more than 100 shooting incidents have occurred since January 1, gun violence is an ongoing issue and it has been for years. Only, these shootings have become so common that they don't make national headlines.


"We lost a classroom full of children in Connecticut which sparked national outrage that needs to be translated into action, but in Chicago, we sometimes lose a dozen or more young people every weekend," Rep. Luis Gutierrez (D-Illinois), who serves the Chicago area, said in a statement. "Too many bullets and too many guns are killing the next generation and we have got to make it stop."


Gutierrez, like many others, believe that any debate about gun violence shouldn't just take into account mass shootings that make headline news. It should also consider the chronic gun violence that takes place on a daily basis across the U.S.


In Chicago's case, many of the victims are young minorities growing up in poor, gang-ridden neighborhoods on the south and west side of the city.


Just earlier this week a 15-year-old girl who performed at President Barack Obama's recent inauguration was gunned down, The Washington Post reported.


The teen, Hadiya Pendleton, was hanging out in a park with about a dozen other young people when she was shot. Two other victims were reportedly wounded. By all accounts she was in the wrong place at the wrong time. Reports indicate that the gunman was not even aiming at her.


And Pendleton is just the latest example. Chicago police officer Ron Holt lost his son, Blair, to gun violence in the spring of 2007. The 16-year-old was shot and killed while riding a bus after school.


Holt now works with young people in the community, particularly minorities at an increased risk of engaging in dangerous behavior, to encourage them to focus on their education instead of turning to violence.


"I explain to them that if they continue to ascribe to this diabolical idea of resolving conflict with firearms they're depleting the most precious natural resource in the community, and that is them," Holt said.


What's clear is that the root of the gun problem is not just the guns. There are several factors that play a role, many of which are rarely discussed. For example, for minority youth living in urban communities characterized by poverty, violence, particularly gun violence, tends to be chronic. And the groups largely impacted tend to be African American and Hispanic.


A lot of that has to do with acculturation, according to Rahsmia Zatar, executive director of Strong Youth, a gang prevention and intervention organization. There is a sense that it's difficult to move beyond one's cultural sphere.


As a result, minorities often tend to gravitate toward other young minorities in similar situations, and turn to violence to gain a sense of control, however false it really is.

"It's easy to fall victim to feeling a sense of empowerment through violence," Zatar said. "They feel they have limited opportunities and they don't have a sense of 'I can achieve,' [or] that there is something here for me that's better."


According to the 2011 American Community Survey by the U.S. Census Bureau, more than 30 percent of Chicago's African-American population and nearly 27 percent of Hispanics live below the poverty line. Perhaps more importantly, blacks and whites remain largely segregated, with African-Americans making up the vast majority of neighborhoods in the south, and whites comprising most of the north. Latinos are somewhat more mixed, often living in "buffer" communities between blacks and whites, which could exacerbate the pressure to conform to two cultures, neither of which is entirely comfortable.


These various enclaves also suffer from a distinct gang problem. Chicago Police Commissioner Garry McCarthy told Reuters the city is plagued by the breakup of larger more established gangs into new factions that are fighting over everything from turf to money.


Then there's the city's illicit gun issue, which is bigger than New York's or Los Angeles' despite strict laws to limit weapons. Gun shops are actually outlawed in Chicago, as are assault weapons and high-capacity magazines. Handguns were even banned until 2010.


Still, in a place like Chicago it's handguns doing the most damage. According to statistics from the Bureau of Alcohol, Tobacco, Firearms and Explosives, most of the guns they recovered in Illinois were pistols, followed by revolvers and rifles. Machine guns come in a distant sixth.


Why so many guns? Gun laws in neighboring communities are not as strict, and firearms make their way into the city. According to a recent article by The New York Times, officials "seized 7,400 guns [in Chicago] in crimes or unpermitted uses last year (compared with 3,285 in New York City), and have confiscated 574 guns just since Jan. 1 — 124 of them last week alone."


And while Chicago residents are required to report the loss or theft of a handgun, that same law does not apply to all of Illinois, so a stolen firearm could easily make its way into Chicago without the owner ever reporting it missing.


The dynamics created in poor minority communities like those in Chicago combined with the sheer number of guns that make their way into such a city bear out in the overall statistics.


According to the Bureau of Justice's National Crime Victimization Survey, African Americans were disproportionately represented among homicide victims and offenders between 1980 and 2008. They were six times more likely than whites to be homicide victims and seven times more likely than whites to commit homicides.


Latinos don't fare much better. According to the National Council of La Raza, the nation's largest Hispanic advocacy organization, "Today in America, every three hours a young person is killed by firearm violence. Every 14 hours, that teen or child is Latino."


Young Latinos are especially likely to be impacted by gang violence in places like Chicago. Nationally, Hispanics are also more likely than non-Hispanics to be victims of violent crimes committed by gang members.


The impact of guns on the Latino community may explain why they're inclined to favor increased gun control. According to the Pew Research Center, while 57 percent of whites think it's more important to protect the rights of Americans to own guns than to protect gun ownership, only 29 percent of Latinos feel the same way.


Holt would certainly like to see something change. Several days after his son was killed, he received a voicemail. It was then-Senator Barack Obama. The young lawmaker had called Holt to express his condolences and to promise that if there was anything he could do in the future to help curb gun violence, he was prepared to do it. The two never spoke on the phone, but Holt remembers the message.

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.

S. Korea, US in naval drill amid N. Korea tensions






SEOUL: South Korea and the United States will hold a joint naval exercise next week, a report said Saturday, a move seen as a warning to North Korea ahead of its widely-expected nuclear test.

The three-day exercise involving a US nuclear submarine and other warships will begin on Monday in the Sea of Japan (East Sea) off the South Korean port city of Pohang, Yonhap news agency reported.

"It will include anti-submarine and anti-air trainings and maritime manoeuverings," a military official was quoted as saying in the report.

The exercise comes as tensions run high on the Korean peninsula, with Pyongyang threatening to carry out its third nuclear test in response to UN sanctions imposed for a long-range rocket launch it carried out in December.

The North said the launch was a scientific mission aimed at placing a satellite in orbit, but most of the world saw it as a disguised ballistic missile test.

South Korea's Joint Chiefs of Staff Jung Seung-Jo said Friday the drill aims to test combat readiness between Seoul and Washington while guarding against possible North Korean provocations involving submarines, according to Yonhap.

A 6,900-tonne US nuclear submarine USS San Francisco and a 9,800-tonne Aegis destroyer USS Shiloh were being mobilised for the exercise.

"The presence of a US nuclear submarine here would itself serve as a message to North Korea", Jung said.

North Korea has reportedly covered the entrance to a tunnel at its nuclear test site in an apparent effort to avoid satellite monitoring of its ongoing preparations for a possibly imminent detonation.

A camouflage net was placed on the tunnel entrance at Punggye-ri in the northeastern North Korea, the site of the two previous nuclear tests in 2006 and 2009.

But a government source in Seoul said that increased activity had been spotted at the site, which has three tunnel entrances and multiple support buildings.

"At a tunnel in the southern part of the test site in Punggye-ri, we've found that work presumed to be part of preparations for a nuclear test has entered its final stage," the unnamed source told Yonhap on Saturday.

"The North may conduct the test at either the western or southern tunnels. But the activities spotted near the southern one could be aimed at distracting us from the more likely place of the western tunnel."

Powertrekk fuel cell charger to be released in Spring




PowerTrekk fuel cell charger

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



(Credit:
Lynn La/CNET)


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



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


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


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



Power your phone in an emergency




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


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

Gov's Handling of Sandusky Case Under Investigation













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


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


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


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


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

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


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


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


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


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


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


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


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

Swarm-mongering: Brainless blobs flock together











































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












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












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











Self-healing swarm













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












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












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











Schooled by fish













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












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












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

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






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

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

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

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

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

The managing agent plans to leverage technology to improve services.

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

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

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

Nokia begins work on graphene, world's strongest material



A model of a sheet of graphene.

Swedish Academy of Sciences)


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

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

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

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

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

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

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

Arias' Lawyer Shows Ex-Boyfriend's Lewd Photos













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


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


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


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


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


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


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

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


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


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


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


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


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


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


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


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


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


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


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


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

2 new commercial belts to bring jobs closer to homes






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

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

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

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

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

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

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

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

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

Microsoft Surface sales well below shipments, says iSuppli



Surface RT tablet.

CNET)


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


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


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


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


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


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


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

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

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

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

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

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

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

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

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

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.

Former Police Captain Cleared of Ex-Wife's Murder













A former Ohio police captain has been cleared in the murder of his ex-wife and released from prison, where he had been for 15 years -- but prosecutors say they plan to appeal the ruling.


"I'm just a jumble of emotions and I just can't wait to hug all of my family," Douglas Prade told reporters outside the prison when he was released Tuesday afternoon, according to ABC News' Cleveland affiliate WEWS-TV.


He thanked "all of the people that supported me and communicated with me and told me to keep my spirits up."


Prade's ex-wife, Dr. Margo Prade, 41, was found shot to death in her minivan outside of her medical practice in November 1997.


Douglas Prade was an Akron, Ohio, police captain at the time.


At trial, he was convicted on murder and wiretapping charges and sentenced to life in prison.


Prade, now 66, maintained his innocence and, eventually, the Ohio Innocence Project took up his cause and petitioned for his release or a new trial based on new DNA testing.


One of the key factors in Prade's conviction was a bite mark found on Margo Prade's body. The prosecution brought in an expert that testified the bite mark came from Douglas Prade.

The Ohio Innocence Project commissioned a new DNA test that was not available at the time of the trial. The test found that the DNA around the bite was not Douglas Prade's.


Summit County Court of Common Pleas Judge Judy Hunter ruled that Prade should be set free because the new DNA results were "clear and convincing" in Prade's favor, according to the Associated Press.


Prosecutor Sherri Walsh is strongly disputing the new DNA evidence.


"This is a gross misapplication of the law, and we will be appealing Prade's exoneration. The defendant had to present new evidence so convincing that no juror would have found him guilty, and he failed to do so," Walsh said in a statement. "The DNA evidence presented by the Ohio Innocence Project on behalf of Prade is contaminated and unreliable. It does not prove innocence."


Walsh said that all evidence points to Prade as the person who killed Margo Prade.


"He was a serial stalker," Walsh said. "He tapped her phones and recorded more than 400 of her personal calls. He had verbally abused and threatened her. And we know Margo was afraid of him."


Other evidence includes Prade's handwritten tally of the bills he owed subtracted from the life insurance money he'd get if his wife died, Walsh said. Two witnesses placed him at the murder scene.


"We have not seen any credible evidence that suggests innocence, and we are taking all available actions to keep a dangerous killer off the streets," Walsh said.


Margo Prade's family is also upset by the decision.


"I feel like my life is in danger and my family's life is in danger now," Margo Prade's nephew Tony Fowler told the AP. "[Dr. Prade and her mother] are probably turning over in their graves but God will have the final say."


Alison McCarty, the former prosecutor on the case, told WEWS she respected the court's decision, but emphasized that the case is not yet closed.


"[Margo Prade] was such a superstar and it was just such a tremendous loss, and her death still needs justice," McCarty said.


The state has 30 days to file a motion in the court of appeals requesting permission to appeal the decision for a new trial.

Million mourners set to honour Cambodia's ex-king






PHNOM PENH: More than one million mourners are expected to line the streets of the Cambodian capital on Friday for a lavish funeral procession for their revered former King Norodom Sihanouk, officials say.

The late monarch's body will be transported atop a golden float shaped like a mythological bird from the royal palace -- where he has been lying in state for three months -- to a funeral pyre in a city park.

"This is our last homage to say goodbye to the great hero king," Prime Minister Hun Sen said on national radio this week.

Sihanouk died of a heart attack aged 89 in Beijing on October 15 last year.

He abdicated in 2004 after steering Cambodia through six decades marked by independence from France, civil war, the murderous Khmer Rouge regime and finally peace.

His body will be kept at the cremation site for religious ceremonies until Monday when his wife and son King Norodom Sihamoni are expected to light the pyre.

Foreign dignitaries -- including French Prime Minister Jean-Marc Ayrault, Japan's Prince Akishino and a host of Asian leaders or high-ranking officials -- are due to attend the cremation.

Flags will fly at half-mast. Radio and TV stations as well as entertainment venues have been instructed to refrain from showing "joyful spectacles", performances and concerts.

Cambodians have been urged to wear black ribbons pinned to their shirts.

"This is the first time in Cambodian history that the country holds such a large funeral for a king," said Sihanouk's long-time personal assistant Prince Sisowath Thomico.

"The nation does this to show him the same respect he gave to the country," he told AFP.

After the cremation, Sihanouk's remains will be put in a golden-colour urn that will be placed in a stupa inside the royal palace, he said, in line with the late monarch's wishes.

Large portraits of Sihanouk have been erected along Phnom Penh's streets and outside the royal palace where people have regularly gathered for religious ceremonies since his death.

"When the King-Father is cremated, it will be a big loss for Cambodia. We will lose our spirit," said Khut Simon, who joined about 100 people for one such ceremony.

"He was a good king who was incomparable," said the 61-year-old, clutching three pictures of the late monarch to her chest.

Sihanouk was just 18 when placed on the throne in 1941 by French colonial authorities, but quickly defied his patron's expectations of a pliant king.

Many elderly Cambodians fondly recall the 1950s and 1960s as a golden era, when Sihanouk led the country to independence from France and a rare period of political stability.

Hundreds of thousands filled the capital's boulevards when his body returned home from China in October.

A self-confessed "naughty boy" who married six times and fathered 14 children, the former king was also a prolific amateur filmmaker and shrewd political survivor who repeatedly backed different regimes.

He was not immune to controversy, notably aligning himself with the communist Khmer Rouge after being ousted by US-backed general Lon Nol in 1970.

After seizing power, the Khmer Rouge put Sihanouk under house arrest in the royal palace. Their 1975-79 reign of terror killed up to two million people, including five of Sihanouk's own children.

Before the Vietnamese invaded and toppled the Khmer Rouge, Sihanouk took exile in China.

He continued to push for peace, which eventually came in the 1990s. Sihanouk triumphantly regained the throne in 1993 but his influence diminished as strongman premier Hun Sen extended his grip on power.

In recent years, Sihanouk -- who battled illnesses including cancer, diabetes and heart problems -- spent long periods of time in China undergoing medical treatment, with his devoted sixth wife Monique always at his side.

Obama backs immigration reform for skilled tech workers



Obama announced today that he backs immigration reform.



(Credit:
White House)


Tech companies may score a victory in their hopes to get immigration reform passed for skilled tech workers.

President Obama urged Congress today to work on immigration policy that would allow foreign-born startup founders to stay in the country. At the same time, several U.S. senators introduced a bill focusing on the same. As U.S. immigration policy currently stands, U.S.-educated computer programmers and engineers could be deported once finishing school.

"Right now in one of those classrooms there's a student wrestling with how to turn their big idea -- their Intel or Instagram -- into a big business," Obama said during a speech in Las Vegas today. "We're giving them all the skills they need to figure that out, but then we're going to turn around and tell them to start that business and create those jobs in China or India or Mexico or someplace else. That's not how you grow new industries in America. That's how you give new industries to our competitors. That's why we need comprehensive immigration reform."

The president mentioned that Instagram was co-founded by an immigrant -- Brazilian Michel Krieger who studied at Stanford University. But, he said, not all startup founders are able to secure visas and stay in the U.S.

In addition to Obama urging Congress to act today, a handful of U.S. Senators -- Orrin Hatch, R-Utah, Amy Klobuchar, D-Minn., Marco Rubio, R-Fla., Chris Coons, D-Del. -- introduced new legislation called the Immigration Innovation Act of 2013. This bill focuses on reforming the country's immigration laws for high-skilled workers. The idea is to increase the H-1B visa cap from 65,000 to 115,000, along with easing green cards rules.

Several tech companies have come out in support of such reform. Google, Intel, and Hewlett Packard all commended the government's efforts on changing the country's immigration policy today.

Google's senior vice president of People Operations, Laszlo Bock, wrote in a blog post today that immigrants founded 40 percent of tech sector companies that went public in the U.S., including Yahoo, eBay, Intel, and Google. And, one in four startups were founded by an immigrant. Combined, these companies employ about 560,000 workers and make $63 billion in sales.

"Our experiences here at Google and in the tech sector show us that immigrants to the U.S. are a powerful force for entrepreneurship and innovation at every level, from startups to multinational corporations," Bock wrote.

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.












Final Farewell: Hillary Clinton Steps Down as Secretary of State 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

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."

"Off the scale" smog envelops Beijing again






BEIJING: Pollution levels in Beijing rose above index limits on Tuesday, the US embassy said, as a dense cloud of haze shrouded large swathes of northern China.

Mask-wearing residents of the capital battled through a second consecutive day of pollution at hazardous levels, despite Beijing municipal authorities warning those with respiratory difficulties to stay indoors.

It is at least the fourth time a dense cloud of haze has descended on northern China this winter, reducing visibility and causing flight delays, with even state media repeatedly expressing anger over the issue.

"The current environmental problems are worrisome," Wang Anshun, who took over as mayor of the Chinese capital this week, was quoted as saying by the official Xinhua news agency.

The US embassy's air quality index (AQI) reading for Beijing stood at 495 and "hazardous" at 11am, after having reached 517, or "beyond index", at 6am.

The index rates anything over 150 as "unhealthy", over 300 as "hazardous", while a reading above the upper limit of 500 is regarded as "beyond index".

Meanwhile, the Beijing Municipal Environmental Monitoring Centre gave the figure at 10am as 393, indicating the air in the capital was "severely polluted".

The toxic air follows an extreme bout of pollution earlier this month, peaking on January 13 when state media said readings for PM 2.5, particles small enough to deeply penetrate the lungs, reached 993 micrograms per cubic metre, almost 40 times the World Health Organisation's recommended safe limit.

The pollution sparked online uproar from residents and outrage from state media who urged officials to confront Beijing's poor air quality.

At the height of the smog, many residents rushed to buy facemasks and air purifiers, and doctors at two of Beijing's major hospitals said the number of patients with respiratory problems had increased sharply during the period.

China's pollution problems are blamed on the country's rapid urbanisation and dramatic economic development.

A total of 61 flights were delayed at Beijing Airport just before 9.30am on Monday, according to its website.

'Citizen cartographers' help Google update maps of N. Korea

Maps of North Korea's landscape have for decades been largely blank, but thanks to "a community of citizen cartographers," Google Maps has managed to fill in some of the blanks.


Tapping input submitted to its Google Map Maker tool, the Web giant has added more detailed, up-to-date information to its maps of the reclusive nation, including streets, names, and other points of interest.


Jayanth Mysore, Google's senior product manager of Map Maker, discussed in a company blog post the effort behind assembling the new data:


To build this map, a community of citizen cartographers came together in Google Map Maker to make their contributions such as adding road names and points of interest. This effort has been active in Map Maker for a few years and today the new map of North Korea is ready and now available on Google Maps. As a result, the world can access maps of North Korea that offer much more information and detail than before.


One area where the changes are most apparent is in the city of Pyongyang, where highways, parks, and even subway stations have been added. Google provided the following examples:

The additions come mere weeks after Google Executive Chairman Eric Schmidt made a controversial humanitarian visit to the country where he warned officials that global Internet access was key to developing its economy.
