Get cirrus in the fight against climate change



































FEATHERY cirrus clouds are beautiful, but when it comes to climate change, they are the enemy. Found at high-altitude and made of small ice crystals, they trap heat - so more cirrus means a warmer world. Now it seems that, by destroying cirrus, we could reverse all the warming Earth has experienced so far.












In 2009, David Mitchell of the Desert Research Institute in Reno, Nevada, proposed a radical way to stop climate change: get rid of some cirrus. Now Trude Storelvmo of Yale University and colleagues have used a climate model to test the idea.












Storelvmo added powdered bismuth triiodide into the model's troposphere, the layer of the atmosphere in which these clouds form. Ice crystals grew around these particles and expanded, eventually falling out of the sky, reducing cirrus coverage. Without the particles, the ice crystals remained small and stayed up high for longer.












The technique, done on a global scale, created a powerful cooling effect, enough to counteract the 0.8 °C of warming caused by all the greenhouse gases released by humans (Geophysical Research Letters, DOI: 10.1002/grl.50122).


















But too much bismuth triiodide made the ice crystals shrink, so cirrus clouds lasted longer. "If you get the concentrations wrong, you could get the opposite of what you want," says Storelvmo. And, like other schemes for geoengineering, side effects are likely - changes in the jet stream, say.












Different model assumptions give different "safe" amounts of bismuth triiodide, says Tim Lenton of the University of Exeter, UK. "Do we really know the system well enough to be confident of being in the safe zone?" he asks. "You wouldn't want to touch this until you knew."












Mitchell says seeding would take 140 tonnes of bismuth triiodide every year, which by itself would cost $19 million.

At least 55 dead in Venezuela prison riot: hospital






CARACAS: At least 55 people were killed and 90 others wounded in clashes between prison gangs and security guards at a facility in northwest Venezuela, a hospital director said Saturday.

Television images had earlier shown National Guard troops surrounding the Uribana prison in Lara state as inmates in bloody clothes were taken out of the building.

Behind the barriers, relatives of the prisoners -- most of them women -- waited for news of their loved ones, many of them in tears.

"There are 55 dead already in the morgue," hospital director Ruy Medina said Saturday.

Around 30 people were still being treated, he said, adding that the patients are "progressing satisfactorily," and that more would likely be released during the day.

Medina had earlier said that most of those injured had suffered gunshot wounds, and that 14 people had injuries severe enough to require surgery.

He had called the initial death toll of 50 "alarming," saying it was based solely on bodies brought to the hospital.

Prison authorities have not yet released an official figure for the toll of those killed and wounded in the riot, but a press conference is expected later Saturday from Iris Varela, the minister responsible for Venezuela's prisons.

Vice President Nicolas Maduro, freshly back in the country after visiting recovering President Hugo Chavez in Cuba, called the riot "regrettable" and "tragic," and said an investigation had been launched.

Varela said the riot was sparked after inmates rebelled when prison authorities launched a sweep of the facility in search of illicit weapons.

Authorities had swept to "completely disarm" the prisoners after receiving a tip-off that prison gangs were readying to fight, she said.

Opposition parties immediately attacked the government, accusing it of exercising lax control over the prison system.

"Who will they blame for this massacre this time around?" opposition leader and former presidential candidate Henrique Capriles said on Twitter, calling the government "incapable and irresponsible."

Humberto Prado, head of the non-governmental Venezuelan Prison Monitoring Organisation, said the government "had failed to take responsibility for the events" and instead was "piling blame on the media."

The situation in Uribana prison has been monitored by the Inter-American Court of Human Rights since 2006, he added.

"The court told the Venezuelan government that no more inmates should be dying in this jail, but the government did not comply with this request, and now we have such a serious outburst of violence," he said.

Venezuela is notorious for the poor state of its prisons, which suffer from some of the highest levels of overcrowding in Latin America.

Originally built to house 14,000 inmates, the country's prisons now hold almost 50,000 people, often with low sanitary standards and high levels of violence.

In August 2012, at least 25 people were killed and 43 wounded during a clash between rival gangs in Yare I prison near Caracas. In June 2011, dozens died in a riot that erupted at El Rodeo prison.

Oppo BDP-105: Not your average Blu-ray player



The Oppo BDP-105 Blu-ray, SACD, and DVD-Audio player

Oppo)


Even by Oppo's high standards the BDP-105 is an extraordinary Blu-ray player. Sure, it's loaded with up-to-the-second features -- 4K upscaling, 2D-to-3D conversion, and a high-quality USB 2.0 digital-to-analog converter -- but what really makes the Oppo special is the sound. Pop the cover and look inside and you'll see why. Most of the 17-pound component's chassis space is devoted to the audio circuitry. That's nice, but the audio advantages will be completely irrelevant if you connect the BDP-105 to your receiver with a HDMI cable (the digital-to-analog conversion would then be handled in the receiver). The 105 was designed for buyers still using older $1,000 or $2,000 receivers from the days before HDMI connectivity, that would like to hear the Blu-rays' high-resolution DTS Master Audio or Dolby TrueHD soundtracks at their best. Since the audio won't be transmitted over the HDMI cable, you would run audio cables between the 105's seven- or five-channel analog outputs and the AV receiver's analog inputs.

Or you could forgo the receiver entirely and hook up the BDP-105 directly to a five- or seven-channel power amplifier. That approach would produce better sound quality, but would lack the connectivity, flexibility, and convenience of today's better receivers. Still, the BDP-105/power amp combo would sound better and be more powerful than most top-of-the-line receivers. The 105's connectivity options won't match any decent receiver, but its connectivity suite is a lot more extensive than most Blu-ray players. The Oppo has two HDMI inputs, so you can connect external devices such as set-top boxes and network streaming devices, three USB 2.0 ports, coaxial and optical digital inputs for satellite boxes, televisions, video-game consoles, etc., and there's a built-in headphone amplifier. The BDP-105's extensive bass management options are on par with a lot of AV receivers. The player's digital volume control is easy to use.


For my listening tests, I hooked up the BDP-105 ($1,199) with an assortment of self-powered Audioengine and Emotiva monitor speakers, and a Hsu subwoofer. With this setup I didn't need to use an AV receiver or separate power amp, but the Raconteurs' "Live at Montreux" Blu-ray was vivid and very live sounding. The system's freewheeling dynamics were really impressive, and the surround mix on King Crimson's "Red" DVD-A projected a remarkably seamless wrap-around soundstage. Each instrument was precisely focused in a near 360-degree sound environment.



The BDP-105 has full speaker setup and bass management options, just like an AV receiver.

Classical music on SACD was just as impressive, the front three speakers produced a three-dimensional soundstage with lots of depth, and string tone was top notch. Dramatic movies on Blu-ray and DVD sounded great. I plugged headphones into the BDP-105, but the sound wasn't special, Schiit Audio's $99 Magni headphone amp was a lot better.


The $499 Oppo BDP-103 shares most of the BDP-105's features, but lacks the upgraded digital-to-analog converters, so if you're planning on using HDMI to connect the player to your receiver, buy the 103, and save $700. You can use the 103's 7.1 analog outputs with an old high-end receiver lacking HDMI connectivity, but the 103's digital converters are a step down from the ones in the 105.


The BDP-105 is an update of the Oppo BDP-95, and the new one has lots of features the old player lacks, but the two players sound about the same. Oppo still has 95s in stock and sells them for $799.


Oppo sells direct and offers a 30-day money-back guarantee, and the return shipping is free.

Dung beetles navigate using the Milky Way









































Ever look up at the stars and wonder if some bug-eyed creature is doing the same? It turns out at least one does: the dung beetle uses the glow of the Milky Way to navigate.











Once a beetle (Scarabaeus satyrus) has constructed its dung ball, it moves off in a straight line in order to escape from rival beetles as quickly as possible, lest they try and steal its carefully crafted ball. This behaviour doesn't sound complicated, but several years ago, Marie Dacke of Lund University in Sweden and colleagues showed that polarised light from the moon is important for dung beetles to keep to a straight line.













Then the researchers were surprised to find the insects were able to stay on course even on a moonless night. "We thought there was something wrong in our set-up," Dacke says.












The team allowed the beetles to crawl around the floor of a plain-walled cylindrical drum with an open top, meaning they could only use the night sky to orientate themselves. The researchers timed how long it took the beetles to reach the edge of the drum from the centre, and found that under a full moon, the insects took around 20 seconds on average; on a starry but moonless night, they took around 40 seconds.












But when beetles had a cardboard cap placed on them to prevent them from seeing the sky, they needed over two minutes, suggesting the stars were playing a role.











Planetarium clincher













To test this, the team moved the experiment to a planetarium. By switching stars on and off, Dacke discovered that the glowing strip of the whole Milky Way was what guided the beetles' movement. "Before it was assumed insects could not use the stars because their eyes don't have the resolution to see them," she says. Navigating using the whole of the Milky Way does away with the need to see individual stars.












Dacke says the results suggest moths, locusts and other insects might navigate by the Milky Way, too. Her team is now looking at whether the beetles prefer to navigate by the moon or the Milky Way when both are on view.

Ito: Think twice about immortality and the singularity




MIT Media Lab director Joichi Ito speaking at the World Economic Forum in Davos, Switzerland

Ray Kurzweil's vision of the "singularity" -- when nanobots make humans immortal and computer progress is so fast that the future becomes profoundly unknowable -- is a bad idea.


That's the perhaps surprisingly contrary opinion of Joichi Ito, who as a high-tech investor and director of the MIT Media Lab might be expected to be a natural ally. The lab, after all, aims to be at the center of today's technology revolution.


Ito, speaking today at the World Economic Forum in Davos, Switzerland, said he believes the singularity vision puts the wrong priorities first.




"I'm on the other side of the singularity guys. I don't think immortality is a good thing," Ito said. People who think about maximizing efficiency "don't think about the ecological, social-network effects. In the future, every science invention we do should be at least neutral," and preferably positive.


"When you introduce immortality, you have to think about what does it do to the system. At the Media Lab, our design principle is not to make the world more efficient, but making the system more resilient, more robust."


Ito called for a radically restructured educational system, too.


"You're training kids to become obedient members of a mass-production society," he said. "But as there's more and more automation, you want people to be more and more creative," like kindergarten when children spend more time playing around, exploring, and teaching each other.


Tests today judge kids in a computer-free testing environment completely unrelated to what's in the real world.


Today, "you can look on the Internet, you can ask your friends," Ito said. "Cheating is actually a feature. Success as an adult is how resourceful you are at getting people to help you do things. Those are all unassessed things" in today's schools and tests.


The MIT Media Lab favors a more unstructured approach. "Our students and faculty can explore whatever they want. We just let them go," he said. "If you're not asking permission and writing proposals, the cost of innovation is very low."


Students can talk about ideas in the morning. "By the afternoon they've built a prototype," he said, especially with the increasing utility of 3D printers.


Ito had grand visions for how those printers will change manufacturing. "We're going to be manufacturing things everywhere instead of centrally. Every single person is going to become a designer," he predicted.


Technology should help people rethink what's possible with cities, he also said. With people able to page buses on demand, bus stops should be created on demand, not fixed in advance. Rentable commuter bicycles should be cheaper to use if people drop them off in high-demand areas.


"We're trying to look at the city from a software perspective and build the hardware around it," Ito said.

Deformed Dolphin Accepted Into New Family


In 2011, behavioral ecologists Alexander Wilson and Jens Krause of the Leibniz-Institute of Freshwater Ecology and Inland Fisheries in Germany were surprised to discover that a group of sperm whales (Physeter macrocephalus)—animals not usually known for forging bonds with other species—had taken in an adult bottlenose dolphin (Tursiops truncatus).

The researchers observed the group in the ocean surrounding the Azores (map)—about 1,000 miles (1,600 kilometers) off the coast of Lisbon, Portugal—for eight days as the dolphin traveled, foraged, and played with both the adult whales and their calves. When the dolphin rubbed its body against the whales, they would sometimes return the gesture.

Among terrestrial animals, cross-species interactions are not uncommon. These mostly temporary alliances are forged for foraging benefits and protection against predators, said Wilson.

They could also be satisfying a desire for the company of other animals, added marine biologist John Francis, vice president for research, conservation, and exploration at the National Geographic Society (the Society owns National Geographic News).

Photographs of dogs nursing tiger cubs, stories of a signing gorilla adopting a pet cat, and videos of a leopard caring for a baby baboon have long circulated the Web and caught national attention.

A Rare Alliance

And although dolphins are known for being sociable animals, Wilson called the alliance between sperm whale and bottlenose dolphin rare, as it has never, to his knowledge, been witnessed before.

This association may have started with something called bow riding, a common behavior among dolphins during which they ride the pressure waves generated by the bow of a ship or, in this case, whales, suggested Francis.

"Hanging around slower creatures to catch a ride might have been the first advantage [of such behavior]," he said, adding that this may have also started out as simply a playful encounter.

Wilson suggested that the dolphin's peculiar spinal shape made it more likely to initiate an interaction with the large and slow-moving whales. "Perhaps it could not keep up with or was picked on by other members of its dolphin group," he said in an email.

Default

But the "million-dollar question," as Wilson puts it, is why the whales accepted the lone dolphin. Among several theories presented in an upcoming paper in Aquatic Mammals describing the scientists' observations, they propose that the dolphin may have been regarded as nonthreatening and that it was accepted by default because of the way adult sperm whales "babysit" their calves.

Sperm whales alternate their dives between group members, always leaving one adult near the surface to watch the juveniles. "What is likely is that the presence of the calves—which cannot dive very deep or for very long—allowed the dolphin to maintain contact with the group," Wilson said.

Wilson doesn't believe the dolphin approached the sperm whales for help in protecting itself from predators, since there aren't many dolphin predators in the waters surrounding the Azores.

But Francis was not so quick to discount the idea. "I don't buy that there is no predator in the lifelong experience of the whales and dolphins frequenting the Azores," he said.

He suggested that it could be just as possible that the sperm whales accepted the dolphin for added protection against their own predators, like the killer whale (Orcinus orca), while traveling. "They see killer whales off the Azores, and while they may not be around regularly, it does not take a lot of encounters to make [other] whales defensive," he said.

Unplanned Pregnancies Hurt Military Women
















Women in the military have access to some of the nation's best health care, which includes free birth control. But a new study shows that many women are not using it and the rate of unintended pregnancy is double that of the general population.


And today, with the Department of Defense having just ended its longtime ban on women serving in combat roles, an unplanned pregnancy could have wider ramifications not only for a woman's health, but for her opportunities for advancement.


An estimated 10.5 percent of active duty women, ages 18 to 44, reported an unplanned pregnancy in the prior 12 months in 2008, the last year for which there are statistics, according to researchers at Ibis Reproductive Health, a nonprofit organization that supports women's sexual and reproductive rights.


That number was higher than in 2005, when the rate was 9.7 percent.


In the non-military population, about 5.2 percent of women of reproductive age report an unintended pregnancy each year, according to the study, published this week in the February issue of Obstetrics and Gynecology.


The Ibis study was based on surveys of more than 7,000 active-duty women; the statistics were obtained from the Department of Defense under the Freedom of Information Act. Rates were equal among those women who were deployed and those serving stateside.


Women make up 202,400 of the U.S. military's 1.4 million active duty personnel; more than 280,000 women have deployed over the last decade to Iraq and Afghanistan.

"It's terrific that women are getting recognition for their role in combat missions and are being considered for all types of promotions in the armed services," said lead author Kate Grindlay, senior project manager at Ibis. "But for women to reach their potential, they must be able to access birth control for their personal health and well-being."


Military warned to maintain readiness as women move toward combat.


About 900 women had been unable to deploy in the past year due to a pregnancy, either planned or unplanned, according to the study. The highest rates were among younger women with less education who were either married or cohabitating, researchers said.


The authors of the study say that an unwanted pregnancy not only disrupts a woman's military career, but takes a toll on military readiness because pregnant women cannot be deployed or must be evacuated from war zones. They say the military needs to take a more "comprehensive approach" to address the problem.


A July 2012 Ibis study, based on women deployed over the last decade, revealed they face a variety of barriers to accessing contraception.
Women said they did not speak with a military medical provider about birth control before they deployed overseas -- either it was never offered or the woman never asked.


Military policies that forbid sexual activity between fellow service members "led some women to think contraception was not available or not needed," said the report.


Others said they had trouble getting preferred types of birth control -- the IUD, for example -- or adequate supplies before deployment.


"In addition to these access barriers, the high rate of sexual assault in the military also puts women at risk of unintended pregnancy," said the July study.


New documentary explores rape in the military.


Abortions are only provided at military hospitals in cases of rape, incest or life endangerment. A woman must either risk an abortion at a local hospital during deployment or be sent home. Tricare, the military insurance plan, does not cover an abortion.


"Women who are deployed in Iraq wouldn't have any abortion options and must be evacuated and it could compromise confidentiality and access to care," said Grindlay.

The real lesson from the bird flu storm






















The controversy over whether work on airborne H5N1 bird flu can be published shows that transparency is vital to upholding public trust





















So the research moratorium on H5N1 bird flu is over. In 2011 I was one of the first journalists to report the discovery that H5N1 bird flu, which is highly lethal in humans, can mutate to become readily transmissible not just in birds but also in mammals like us – while, apparently, remaining lethal.












What happened next shocked the researchers. Publication of the work was blocked, as US biosecurity experts insisted it would be crazy to tell would-be bioterrorists about this. The 39 labs around the world that do this research responded by declaring a moratorium on further work: there's little point doing research you can't publish.












A year later, the US will shortly launch a new review process to address this. This week, the labs said they would soon resume work on whether, and how, a virus now evolving across Eurasia might become an apocalyptic threat to humanity.












This resumption is good news – but there's a proviso. Hypothetical bioterrorists aside, the real worry for many critics is the danger posed by research itself. We don't want labs to inadvertently release the virus we fear.












That doesn't just require stringent containment and more bureaucracy – it means doing experiments only when benefits really outweigh risks. If, as seems likely, all parties involved cannot agree on that, then the whole process should at least be as transparent as possible. Top research officials in the US have been saying this, and that too is good.












Alarming spin













But are researchers as committed to transparency? The H5N1 kerfuffle has been notable for an alarming amount of spin. Details of the findings have been reinterpreted as pressures have mounted. The experience may have left some researchers even less likely to tell us what they're doing.












The story emerged at a flu meeting in Malta in September 2011. Ron Fouchier of the Erasmus Medical Center in Rotterdam reported that he had made H5N1 able to spread between ferrets via airborne droplets, by simply passing it repeatedly between the animals.












This was the $64,000 question in flu research. At present, H5N1 cannot become a human pandemic as it does not spread this way in mammals. But can it evolve this ability? Some virologists said no. Others said it might, but the mutant would not be as lethal.












No such luck. "All the ferrets died," Fouchier told me. "We have to do more to control H5N1." He was clearly upset at the prospect of such a virus evolving naturally; so were other flu researchers at the meeting. I reported it












Fouchier had left out a lot of detail as the research had been submitted to the journal Science, which doesn't allow authors to say much before publication. When he said the ferrets all died, I thought he was referring to the ones that inhaled the virus. In fact those ferrets lived; the ones that died had had that same virus put into their windpipe.












We would have corrected the article had the researchers complained. Maybe it seemed a minor point: the team had also reported that putting a flu virus in a ferret's windpipe was the best test of its danger to humans. The transmissible virus killed in a way that might be relevant to people – that's what mattered. The detail wouldn't have changed our conclusion.











Dangerous or not?













But then the dispute over whether the work could be published blew up, and The New York Times charged that this research was just too dangerous.












In February last year, the researchers' story had changed dramatically. The press had blown things out of proportion. The mutant virus wasn't dangerous. None of the ferrets that inhaled it died, you had to practically shove it into their lungs to kill them. Anyway, animal work doesn't show what will happen in people.












Efforts to portray the transmissible virus as harmless were almost comical. One researcher told me the mutant H5N1 was no biggie – even the 2009 pandemic flu kills in ferrets' tracheas. Ah, but only one in three – the H5N1 killed them all, so not quite the same.











When the research was finally published, none of the spin seemed very relevant. The message of Malta remained: H5N1 became airborne in mammals, and could still kill. That's enough. Yes, this is animal work: if a virus that kills in a ferret's throat, but not in its nose, emerges in nature, we may get lucky. Or maybe we'd best not inhale.












Full transparency













Some defensiveness is understandable if scientists fear work they rightly consider vitally important may be banned. Yet full transparency is the answer. I fear that lesson has not sunk in. After the papers were published, one of the researchers insisted to me that there was no reason why he should ever talk to a journalist; this week that person begged journalists to tell the public the researchers' side of the story, so they wouldn't get this kind of opposition.











That's not how it's done. Transparency is an important safeguard against some who may take excessive risks (it happens) as well as showing the good that scientists do. It must serve both these functions, or no one will believe the good news.













I gave a talk in Malta too, about public communication. I told a roomful of flu researchers the old risk-management saying: strive to be, not trusted, but accountable. I got a lot of blank, angry stares.












This problem won't go away until that gets rueful, knowing nods. It isn't happening yet.

Keppel Corp's net profit falls 22% on-year in Q4






SINGAPORE: Falling margins from building oil rigs has hit the bottomline of Keppel Corp.

Net profit for the world's leading rig builder fell 22 per cent on-year to S$305 million in the fourth quarter last year.

Still, full year profit for the conglomerate came in 15 per cent to S$2.24 billion.

Despite lower net profit in the three months ended Dec 31, Keppel Corp still declared a final dividend of 27 cents per share.

As part of its 45th anniversary, Keppel Corp is handing out more goodies to its shareholders.

The company has proposed to distribute one Keppel REIT unit for every five Keppel Corp shares.

That is about 27.4 cents per share based on Keppel REIT's closing price of S$1.37 on Thursday.

Together with the interim dividend of 18 cents, total distribution for 2012 will be 72.4 cents per share.

Keppel Corp said the lower net profit was partly due to lower contributions from its offshore and marine unit.

Offshore and Marine's contribution was 12 per cent lower from a higher base in 2011 when margins were at record highs. It contributes to half of Keppel Corp's net profits.

"Keen rivalry from Chinese and Korean yards have suppressed prices and squeezed margins on newbuilds," said Choo Chiau Beng, chief executive officer at Keppel Corp. "In 2013, we will be completing a record of 22 newbuild units."

Analysts remained upbeat of Keppel's prospects going forward.

They say their financial results still outperformed market expectations.

Keppel Corp expects crude oil prices to stay above US$100 per barrel, supporting the need for more global exploration and production.

But global challenges like the slower US economy and the eurozone crisis from last year will continue to pose uncertainties for Keppel Corp's business.

Keppel Corp's property arm, led by the listed Keppel Land, boosted the group's earnings.

Net profit for the property division was 2.5 times higher than in 2011, offsetting the lower earnings from business in the offshore and marine, and infrastructure.

But Keppel Corp does not expect its property arm to perform better this year.

This is because recognition from sales of completed units at its development Reflections at Keppel Bay is expected to be lower this financial year.

Twitter unveils Vine, its six-second Instagram for video



Twitter today unveiled Vine, an app for iOS that lets anyone create and share short looping videos.


Twitter acquired Vine last fall, but anyone can use Vine regardless of whether they use Twitter. However, the service is clearly meant to be embedded anywhere, and there are plenty of examples of the videos being embedded in tweets. The service (see an example below) is being referred to by many as Twitter's "Instagram for video."



Vine videos are limited to a maximum of six seconds, and play in a continuous loop. They are shot using the Vine app. In a blog post, Vine co-founder and general manager Dom Hofmann wrote that, "Posts on Vine are about abbreviation -- the shortened form of something larger. They're little windows into the people, settings, ideas and objects that make up your life. They're quirky, and we think that's part of what makes them so special."




It's not clear, however, if Vine posts have a technical limitation that keeps that six seconds or shorter. Neither Twitter nor Vine immediately responded to a request for comment.


Although Twitter officially unveiled the service today, CEO Dick Costolo teased it yesterday when he posted a tweet with an embedded video. What was not clear yesterday, however, was whether Vine was going to become Twitter's own hosted video service, or if, as turned out to be the case, it would be a stand-alone service that works in conjunction with Twitter, but doesn't depend on it.


There are of course other embeddable short video services. One is Tout, a service that lets people shoot videos of up to 15 seconds, and then either embed them in tweets, Facebook posts, blogs, or elsewhere, or view them directly on the Web. But Twitter seems to have decided that Vine was a service worth buying, despite the fact that it will allow it to exist independently.

Exterminator Charged in Pa. Doctor's Murder













An exterminator named Joseph Smith was arrested and charged today in the strangling and burning death of Philadelphia pediatrician Melissa Ketunuti.


Smith, 36, had been sent to Ketunuti's home on a service call where the two got into "some kind of argument" in Ketunuti's basement on Monday, Capt. James Clark of the Philadelphia police department said this morning.


"At her home they got into an argument. It went terribly wrong. He struck her, and knocked her to the ground," Clark said. "Immediately he jumped on top of her, started strangling her. She passed out, and then he set her body on fire."


Clark said Smith burned the woman's body "to hide evidence like DNA." He said "at some point, he bound her up." The doctor was found with her hands and feet tied behind her back.


The captain said that before today's arrest Smith's record consisted of only "minor traffic offenses."

Police received a call from Ketunuti's dog-walker about the house fire around 12:30 p.m. Monday, and once inside found Ketunuti with her hands and feet bound. They believe Smith hit her and strangled her with a rope, causing her to pass out, and then bound her body and set fire to it in order to destroy evidence, including DNA evidence.


Ketunuti, 35, was fully clothed and police do not believe she was sexually assaulted.


She was a doctor at Children's Hospital of Philadelphia and had lived alone in the Graduate Hospital neighborhood of the city for about three years.


Clark said that homicide detectives scoured the neighborhood for surveillance videos from nearby stores and businesses, and through the video identified the suspect.


Smith was spotted on video getting out of the vehicle and following Ketunuti to her home. The man left her home after an hour and was seen on video circling her home.


Detectives drove to Clark's home in Levittown, Pa., outside of Philadelphia where he lives with a girlfriend and her child, on Wednesday night and brought him back to the Philadelphia police station.


A silver Ford truck was towed from Smith's home, which was the same truck spotted on surveillance video Monday in Ketunuti's neighborhood, sources told ABC News affiliate WPVI.


There, he gave statements that led police to charge him with the murders, Clark said.


Smith will face charges of murder, arson, and abuse of a corpse.


Ketunuti's hospital issued a statement Tuesday that she was "a warm, caring, earnest, bright young woman with her whole future ahead of her," adding that she will be deeply missed.


"[She was] super pleasant, really nice," one neighbor said. "Just super friendly."

Can we really 'cure' autism?






















Some claim that new research shows people can grow out of autism, but it is more likely that they simply cope better with the condition over time






















The New York Times has pointed to an intriguing study ostensibly showing that some small percentage of people with autism can "outgrow" their symptoms. The story was oddly unsatisfying, claiming in one paragraph that the study, published in The Journal of Child Psychology and Psychiatry, will alter the way parents "think and talk about autism" but also cautioning against false hope.












The writer seems only dimly aware how this half-hearted message will set off a bomb in the world where Jenny McCarthy lives – that she will turn on that wicked grin and brandish this study to launch another 40 years of vicious debate over whether autism is caused by environmental factors, namely vaccines, and thus can be cured by brave and dedicated parents like her, or whether it's just a condition people are born with.












Thankfully, science writer Emily Willingham has parsed through the study in Forbes to show us what it really finds, which is not much that's new and certainly nothing that will change our thinking about the progress of autism or make us believe in the McCarthy miracle cure. As Willingham points out, the people who seem to have "grown out" of their autism had higher cognitive functioning and milder symptoms in the first place, and "many of them had behavioral interventions in childhood".












One measure the researchers used to evaluate progress was "typically developing friends", which people with autism sometimes have anyway. Seven of the 34 had some impairment in "non verbal social interactions" which the researchers decided, somewhat arbitrarily, was due to other factors such as anxiety or depression.












Anyone who has read a single memoir by someone with Asperger's or known someone well with the condition can intuit what's going on. At the moment, I happen to be reading Look Me in the Eye: My life with Asperger's by John Elder Robison. Over the course of his life, Robison learns to compensate for his social limitations. As a child he teaches himself to say appropriate things to children and not just foist on them his own obsessive interests. As an adult he learns that blurting out the truth – "you look fatter" – is not always the right thing to do.











Working around autism













He doesn't "outgrow" his autism, he just learns to work around it. Even later in his life he writes that he wishes his disability were more obvious; when we see someone in a wheelchair we know they can't walk, so we help them across the street. There is no way to "see" Asperger's so people just assume he's a jerk.












Willingham makes the comparison to diabetes, which I have. I have learned how to control my blood sugar pretty well, but I still have diabetes. Autism for high-functioning kids works something like that, even more so these days.












When Robison was a kid, no one understood him at all. They just thought he was odd and would grow up to be a failure. But now there is a well-developed understanding of Asperger's and its symptoms, and many behavioural therapies that can help people, especially if they are smart enough to absorb them. So it stands to reason that as time goes on, more people with Asperger's or autism will look, to all the world, as if they are "cured" without actually being so.

Japan presses Algeria for answers as toll hits nine






ALGIERS: A senior Japanese official met Algeria's prime minister on Wednesday to press for an explanation of the gas plant siege, as Tokyo confirmed the deaths of two more nationals, taking its toll to nine.

Senior Vice Foreign Minister Shunichi Suzuki arrived aboard a government jet that is to repatriate the bodies of those known to have been killed in the hostage crisis, along with the seven Japanese who survived.

Tokyo announced late Wednesday that it knew for sure that nine Japanese were killed after Islamist gunmen overran the desert facility. One Japanese citizen remains unaccounted for.

"Unfortunately, we have been able to confirm two more deaths," said Chief Cabinet Secretary Yoshihide Suga. "The Japanese government expresses sincere condolences to the families and people concerned."

"The use of violence cannot be tolerated for any reason. We firmly condemn acts of terror," he said adding the government would do its utmost to confirm the fate of the final missing person.

Seventeen Japanese were at the facility in In Amenas when jihadists struck last Wednesday at the start of a four-day siege that left dozens of foreigners dead. Seven of them made it to safety.

Suzuki carried a letter to Algerian President Abdelaziz Bouteflika from Japan's Prime Minister Shinzo Abe, Suga told reporters in Tokyo earlier.

As well as Prime Minister Abdelmalek Saleki, Suzuki also met Foreign Minister Mourad Medelci, Japan's Kyodo News reported, citing Tokyo's foreign ministry.

Japan has asked Algeria to fully investigate events at the gas plant and exactly how individuals died, Suga said in Tokyo.

"Algeria has promised to cooperate as much as possible," he said.

Algeria has said 37 foreigners of eight different nationalities and an Algerian were killed in the siege, which ended on Saturday.

Several people are still missing and the bodies of others are so badly charred that they have not been identified.

Wednesday's visit came as it emerged that Britain, Japan, the United States and other countries whose nationals were caught up in the events at the In Amenas plant issued a joint demarche to Algeria last Friday.

A demarche is a formal diplomatic move in which a country's stance is conveyed in person -- rather than by note -- to another government.

In a conference telephone call, vice foreign minister Minoru Kiuchi told foreign minister Medelci that Tokyo wanted Algiers to do all it could to protect captives.

"Japan is strongly concerned about acts that put the lives of the hostages at risk, and it is regrettable that the Algerian government pressed military rescue operations," he said, according to the foreign ministry.

Japan was among the more forthright of nations as the hostage crisis unfolded, summoning Algiers' ambassador to demand answers and to push for military restraint as armed forces surrounded the plant.

The Japanese plane's arrival in Algiers came as Tokyo announced it was shutting its embassy in neighbouring Mali, evacuating staff and urging its nationals there to leave because of the deteriorating security situation.

The kidnappers claimed they launched their attack in protest at Algeria's complicity in a French military campaign against Islamists in Mali.

The Japanese death toll in Algeria -- the highest in a terror attack since Al-Qaeda crashed airliners into New York's Twin Towers when 24 Japanese died -- has shaken a country not accustomed to its citizens being made targets abroad.

There has been blanket media coverage of events half a world away and anguished demands for more to be done to protect Japanese working in trouble spots, including beefing up spy networks.

Kyodo on Wednesday said Suga indicated Tokyo's willingness to consider increasing the number of defence attaches at Japanese embassies to strengthen the country's ability to gather information.

"I am aware of the need. We need to think about the most effective (crisis-response) measures," Suga said.

Surface RT tablet to get update glitch fix -- in February



Microsoft Surface RT

Hang in there, Surface RT users.



(Credit:
Josh Miller/CNET)


Microsoft is working on a fix for Windows RT users hit by application-updating problems that seemingly were introduced by the latest set of updates Microsoft pushed out for the operating system earlier this month.


As The Next Web noted late last week, some Surface RT users have not been able to access the Windows Store or Windows Update since applying the latest set of Patch Tuesday fixes, rolled out on January 8. A firmware update for Surface RT devices was also part of the batch of updates delivered at that time.


A Microsoft spokesperson said the company expects to have a fix ready by early February. Here's the official statement:


Some Windows RT customers who attempted to apply January's bulletins had issues installing updates. Specifically, impacted Windows RT devices went into connected standby mode during the download of updates from Windows Update, causing the connection to be disrupted. We apologize for any inconvenience this may have caused and are working to correct the issue; we expect to have a fix in place in the first week of February.

The spokesperson's statement noted that the coming fix will be for all ARM-based Windows RT devices. Surface RTs comprise the significant majority of systems running the Windows RT operating system at this point.


Microsoft officials announced yesterday that the company will expand Surface RT's availability to customers in 13 Western European markets beyond the countries where it is available now. (Surface RT is already available in Australia, Canada, China, France, Germany, Hong Kong, the United Kingdom and the U.S.) Microsoft also plans to make available a 64GB version of the Surface RT that isn't bundled with the black Touch Cover for $599.


One final note: As part of Microsoft's Surface-related announcements yesterday, officials started using the slightly shorter (but still awful) "Surface Windows RT" and "Surface Windows 8 Pro" names to refer to the first two Microsoft-made PC/tablet hybrids. Before yesterday, the products were known officially as "Surface With Windows RT" and "Surface With
Windows 8 Pro." I'm not sure why Microsoft doesn't just call them Surface RT and
Surface Pro like most of the rest of us do. But there you have it.

Pictures: Trout vs. Trout in Yellowstone Lake

Photograph by Jay Fleming

Without aggressive management, the population of Yellowstone cutthroats could be decimated. To suppress the population of lake trout, the National Park Service engaged a contract fishing company to net them. Cutthroats are removed carefully from the traps and thrown back. Lake trout are removed and killed. Last year about 300,000 of the non-native intruders were taken from the lake.

Clinton Says Budget Cuts Undermine Security













Outgoing Secretary of State Hillary Clinton stood her ground today, telling the Senate Foreign Relations Committee that she has overseen plans to secure diplomatic outposts around the world while cuts in State Department funding undermine those efforts.


Citing a report by the department's Accountability Review Board on the security failures that led to the deaths of four Americans in Benghazi, Libya, during an attack last year, Clinton said the board is pushing for an increase in funding to facilities of more than $2 billion per year.


"Consistent shortfalls have required the department to prioritize available funding out of security accounts," Clinton told the Senate this morning, while again taking responsibility for the Benghazi attack. "And I will be the first to say that the prioritization process was at times imperfect, but as the ARB said, the funds provided were inadequate. So we need to work together to overcome that."


Clinton choked up earlier in discussing the Benghazi attack.


"I stood next to President Obama as the Marines carried those flag-draped caskets off the plane at Andrews," Clinton said this morning, her voice growing hoarse with emotion. "I put my arms around the mothers and fathers, sisters and brothers, sons and daughters."


Clinton is the only witness giving long-awaited testimony before the Foreign Relations Committee right now, and will appear before the House Foreign Affairs Committee at 2 p.m.

The secretary, who postponed her testimony in December, started today by giving context to the terrorist attack.


"Any clear-eyed examination of this matter must begin with this sobering fact," Clinton began. "Since 1988, there have been 19 Accountability Review Boards investigating attacks on American diplomats and their facilities."


But the secretary did not deny her role in the failures, saying that as secretary of state, she has "no higher priority and no greater responsibility" than protecting American diplomats abroad like those killed in Benghazi.


"As I have said many times, I take responsibility, and nobody is more committed to getting this right," Clinton said. "I am determined to leave the State Department and our country safer, stronger and more secure."


Clinton testified that the United States needs to be able to "chew gum and walk at the same time," working to shore up its fiscal situation while also strengthening security, and she refuted the idea that across-the-board cuts slated to take place in March, commonly referred to as sequestration, were the way to do that."


"Now sequestration will be very damaging to the State Department and USAID if it does come to pass, because it throws the baby out with the bath," Clinton said.


While the State Department does need to make cuts in certain areas, "there are also a lot of very essential programs … that we can't afford to cut more of," she added.


More than four months have passed since the attack killed U.S. Ambassador Christopher Stevens and three other Americans in Libya. These meetings, during which Clinton discussed the report on State Department security failures by the Accountability Review Board, were postponed because of her recent illness.


Clinton told the Senate that the State Department is on track to have 85 percent of action items based on the recommendations in the Accountability Review Board report accomplished by March, with some already implemented.

Barack Obama promises US action on climate









































President Barack Obama yesterday vowed to put the fight against global warming at the heart of his next four-year term in office.











Sweeping aside years of American prevarication on whether to act on emissions, Obama promised the US would lead the world in its efforts to curb global warming, and in the development of the technologies to achieve this goal.













"We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations," he said on Monday in his inaugural address to the nation.











Overwhelming judgement












With the horrors of superstorm SandyMovie Camera and the recent US droughts fresh reminders that extreme weather events are becoming more severe and frequent – a trend predicted by climate models – Obama sniped at Americans who still deny that human activity is to blame.













"Some may still deny the overwhelming judgement of science, but none can avoid the devastating impact of raging fires and crippling drought, and more powerful storms," he said.












Obama flagged a transition to cleaner energy as an economic opportunity, one that would be lost to other nations unless the US stepped up. "The path towards sustainable energy sources will be long and sometimes difficult, but Americans cannot resist this transition, we must lead it.












"We cannot cede to other nations the technology that will power new jobs and new industries," said the president. "We must claim its promise. That's how we will maintain our economic vitality and our national treasure, our forests and waterways, our crop lands and snow-capped peaks."











Clarion call













Environmental groups responded enthusiastically. "President Obama's clarion call to action on the threat of climate change leaves no doubt this will be a priority in his second term," Alden Meyer of the Union of Concerned Scientists told New Scientist.












"The politics are shifting rapidly on climate change and clean energy issues, in the wake of the recent drought, wildfires, hurricane Sandy and other extreme weather events," said Meyer. "With presidential leadership, that shift will continue and deepen over the next four years, and meaningful progress on climate change will become an important part of Obama's legacy as president."












"This is a call to action against the climate chaos that is sweeping our nation and threatening our future," said Frances Beinecke, president of the Natural Resources Defense Council (NRDC) in Washington DC. "Now it's time to act. Power plants are our single largest source of carbon pollution and we must cut that pollution. We must do it now, for the sake of our country, our children and the future we share."











Spectre at the feast













Although the president and his Republican opponent, Mitt Romney, avoided discussing climate change in their televised debates prior to the election, Obama hinted of action to come in his post-election news conference, promising a "wide-ranging conversation" on climate change.











His new commitment also adds flesh to promises made four years ago in his first inaugural address to "roll back the spectre of a warming planet".












This time, he also has tactics in hand to outmanoeuvre the entrenched Republican opposition that foiled his attempts in 2010 to give the Environmental Protection Agency (EPA) power to regulate emissions of greenhouse gases.













According to The New York Times, new legislation is currently being drafted to enable the EPA to clamp down on dirtier, coal-fired power plants. Environmentalists are confident this can be achieved. The NRDC last year proposed a plan that would reduce carbon pollution from coal-burning power plants by a quarter, which would cut the total US carbon footprint by 10 per cent.











There are also increasing signs that as the Obama joins the battle against climate change, he has the American people on his side. A pre-election poll showed that most Americans now accept that global warming is caused by human activity.













But environmentalists warned of battles to come. "It will now take a sustained campaign by the president, his cabinet officials and the rest of his team to mobilise the American people in support of this effort, and to overcome the opposition of entrenched interests to the rapid transition away from fossil fuels that's needed to stabilise the climate," says Meyer.

SGX's Q2 net profit rises 17% to S$76m






SINGAPORE : Rising interest in derivatives trading helped lift earnings for the Singapore Exchange (SGX) last quarter.

Asia's second-largest bourse operator reported a 17 per cent on-year rise in second-quarter net profit to S$76 million.

It also attracted a large number of new bond listings in the same quarter.

Derivatives trading has been the star performer in SGX.

Over the October to December quarter, derivatives daily average volume on SGX hit a record of 358,532 contracts, up 30 per cent on-year.

This was supported by rising trading interests in China A50 futures and Japan Nikkei 225 options.

Not to be undone, the securities market performed well too.

Its daily average volume rose 8 per cent for the quarter to hit a trading value of S$1.2 billion.

This translates to a revenue of S$58 million for the securities business segment.

SGX said the better performance was due to improvements in investor sentiment following stability over the Europe debt situation and improved US economy.

Magnus Bocker, chief executive officer of Singapore Exchange, said: "We should remember the enormous amount of liquidity in the market. Not so much in the equity market, but actually more in the fixed income and currency markets, and with chasing yields and lot of very successful and growing companies, I think we can all expect this sentiment to continue. I think we can expect more flows into securities."

Some analysts are bullish on SGX's prospects going forward.

The said the improved investment climate globally may benefit the exchange operator.

Ken Ang, investment analyst at Phillip Securities Research, said: "SGX is very well placed to benefit from this increasing attractiveness of the equity market and therefore resulting in increase in trading value."

SGX attracted eight new listings in its second quarter - raising S$798.9 million.

While the number seems small, it came amid declines in the global initial public offering (IPO) market.

In 2012, global IPO volumes fell 27 per cent, with the lowest level of funds raised since 2009.

Kenneth Ng, head of Singapore research at CIMB Research, said: "I think while that (derivative) is great and that diversified the revenue of SGX, SGX still has a rather pertinent problem of trying to increase the security turnover velocity and value by retail initiatives, attracting listings and so forth."

Apart from seeking more IPOs, SGX also attracted some 90 new bond listings, raising S$39.7 billion for the quarter.

Video showdown set for March in Web-chat debate




After a fractious false start last year, Web standards makers will reconvene in Orlando, Florida, this March to try to settle a debate about the best video technology for browser-based chatting.


The Web-based chat standard, which holds the potential to bring Skype-like audio and video communication services to the Web, is called WebRTC. The debate about it centers on how best to compress video: the widely used industry-standard H.264 codec, or Google's royalty-free, open-source VP8 codec?


The discussion took some surprising twists and turns late last year -- including Google's last-minute action to postpone discussion because of unspecified intellectual property issues and a vote by H.264 patent holders about whether to offer that codec for free.


If this debate sounds familiar, it's because Web standards setters already hashed it in recent years when dealing with Web video. There, fans of H.264's quality and widespread support pitted against those who gnash their teeth at patent-encumbered technology erecting toll booths on an an Internet otherwise built from free-to-implement standards.


HTML5 introduced built-in video, in principle letting Web developers use it as easily as they do images and no longer requiring them to rely on a plug-in like Adobe Systems' Flash Player.




But the HTML5 video standards world couldn't agree on a codec -- the technology that defines how to encode and decode video so it can be sent over a network or stored on a disk in compressed form. Some prefer the H.264 codec, which is built into
Windows 7 and 8, OS X, iOS, and
Android, but which requires royalty payments to patent holders when shipped in products. Others prefer Google's VP8, a later arrival that Google is trying to promote as part of the WebM project.


Now we have the sequel to that debate, this time for real-time communications on the Web.


Separately from the codec issue is the RTC issue. The leading contender, backed notably by Google and Mozilla, is a standard in the making called WebRTC. Microsoft arrived later with a lower-level competing proposal called CU-RTC-Web. Burt regardless of which form of real-time video and audio chat arrives on the Web, a video codec will be necessary.


Standards makers had agreed to a show-of-hands vote on H.264 vs VP8 in November to see if they could pick a mandatory-to-implement (MTI) codec -- in other words, the one that would be required for software to say it supported the standard. That could have been a huge boost for encouraging VP8 adoption, which has been lackluster so far.


But at the last minute -- literally -- Google asked to postpone the issue because of unspecified intellectual property rights (IPR) issues at the Internet Engineering Task Force (IETF), one standards group involved in the real-time communications standard.


In a mailing list message, Google's Serge Lachapelle said:


Google understands that concerns have been raised within the IETF RTCWEB WG [Real-Time Communication in Web browsers Working Group] regards to VP8 IPR...


Google likes VP8
Google believes strongly that the VP8 codec is the best technical option for a mandatory to implement codec.


We therefore kindly ask to postpone this decision and hope the workgroup will take this opportunity to make progress on other vital topics.


The postponement is for the IETF's upcoming meeting in Orlando from March 10 to 15. That postponement didn't sit well with some.


"This not a 'VP8 project', VP8 stands as a possible candidate, one of a set. It seems you are having trouble putting it formally on the table. Are you sure that those troubles can be resolved in a defined interval?" said Apple's David Singer." And, unsurprisingly given Apple's fondness for H.264, he also offered veiled support for that option: "The best *technical* option is almost certainly something widely deployed, implemented, and understood."


Added Nokia's Markus Isomaki, "I agreed to the proposal to drop the discussions since I was pretty sure we would not learn much new or reach any consensus over this. However, could you elaborate a bit what lead to your request just 5 minutes before the start of the session? I mean, concerns about VP IPR status have been raised all along the way and probably will continue to be."


Google didn't respond to that message or to a CNET request for comment on the issue.


VP8 has been dogged by intellectual property issues since it emerged two and a half years go, but so far there have been no legal challenges. MPEG LA, which licenses the large pool of H.264 patents, however, said VP8 violates 12 organizations' patents without disclosing which.


Royalty-free H.264?
MPEG LA got involved in the issue, too, at the behest of t The other standards group working on WebRTC, the World Wide Web Consortium (W3C), doesn't like the idea of patent payments in Web standards -- in fact, it's explicitly against its policy. Shortly before the November vote at the last IETF meeting, therefore, the W3C's highest authorities in effect weighed in against H.264.


"Whatever codec the [IETF's] rtcweb Working Group might choose, we encourage the working group to work toward technologies that implementers can be confident are available on a royalty-free basis, and W3C is willing to work with the IETF in achieving this," said none other than World Wide Web creator Tim Berners-Lee, along with W3C Chief Executive Jeff Jaffe, Philippe Le Hegaret, who leads the W3C's HTML work, and Thomas Roessler, a W3C technology leader.


The message dropped a juicy little nugget into the debate: the possibility of free H.264 use.


That might sound improbable, but MPEG LA granted free rights in perpetuity to use H.264 for Web sites that offer free streaming videos. But the W3C suggested that it might not be wise to get any hopes up for more free rights -- because it asked for those already in the earlier HTML5 video debate:


In 2011 W3C approached MPEG LA, the licensing authority for the generally-known patent pool for H.264, with a proposal for royalty-free licensing of the H.264 baseline codec, to be referenced for use by the HTML5 video tag. MPEG LA was receptive to this proposal; however, the proposal was turned down by a narrow margin within the MPEG LA membership.


Realistically, it's quite possible there will be no decision even March. And even if there is, the debate about the best codec doesn't look like it'll end anytime soon.


Because VP8 vs H.264 is only part of the codec debate. As new technologies appear, the video world is starting to move onto the next phase: H.265 vs. VP9.

Newly Discovered Nebula Looks Like a Manatee


It's a bird, it's a plane, it's ... a manatee? The National Radio Astronomy Observatory (NRAO) believes that a gas cloud in the constellation Aquila bears an uncanny resemblance to the endangered aquatic mammal.

Heidi Winter, executive assistant to NRAO's director, first noticed the similarity. And Tania Burchell, an NRAO media producer who used to work in manatee conservation, quickly saw it as "a wonderful opportunity to bridge two worlds—biology and astronomy."

The cloud, or nebula, which is named W50, has more in common with manatees than just its shape. It is the remnant of a star explosion from 20,000 years ago. Particle beams that shoot from the explosion's center, where a star and a black hole orbit each other, form a spiral pattern resembling scars.

Manatees also bear scars. "Around 80 percent of manatees in Florida have visible scarring," said Michael Lusk, manager of Crystal River National Wildlife Refuge. Because manatees prefer shallow water, collisions with boat propellers are frequent.

The resemblance continues. Like the "sea cow," which can blend into murky water, the nebula is hard to spot. It's approximately 18,000 light-years away, so only one bright arc can be seen by the human eye. Astronomers first saw the ghostly nebula with a telescope that collects a kind of light that radiates at longer wavelengths called radio waves.

W50's new nickname, the Manatee Nebula, and its first photos were unveiled January 19 at the Florida Manatee Festival. "People have an underlying love for the natural world—sky or sea," said Burchell. "We're human beings on this planet, looking up or looking down."

The event marks the 40th anniversary of the Endangered Species Act, which aims to protect critical habitats. Florida's manatee population has risen from around 700 in the 1970s to 5,000 today, and the U.S. Fish and Wildlife Service is considering reclassifying the species from endangered to threatened.

Group Finds More Fake Ingredients in Popular Foods













It's what we expect as shoppers—what's in the food will be displayed on the label.


But a new scientific examination by the non-profit food fraud detectives the U.S. Pharmacopeial Convention (USP), discovered rising numbers of fake ingredients in products from olive oil to spices to fruit juice.


"Food products are not always what they purport to be," Markus Lipp, senior director for Food Standards for the independent lab in Maryland, told ABC News.


In a new database to be released Wednesday, and obtained exclusively by ABC News today, USP warns consumers, the FDA and manufacturers that the amount of food fraud they found is up by 60 percent this year.


USP, a scientific nonprofit that according to their website "sets standards for the identity, strength, quality, and purity of medicines, food ingredients, and dietary supplements manufactured, distributed and consumed worldwide" first released the Food Fraud Database in April 2012.


The organization examined more than 1,300 published studies and media reports from 1980-2010. The update to the database includes nearly 800 new records, nearly all published in 2011 and 2012.


Among the most popular targets for unscrupulous food suppliers? Pomegranate juice, which is often diluted with grape or pear juice.


"Pomegranate juice is a high-value ingredient and a high-priced ingredient, and adulteration appears to be widespread," Lipp said. "It can be adulterated with other food juices…additional sugar, or just water and sugar."








Woman's Legs and Fingers Amputated After Dog Bite Watch Video









Hope Grows for Girl With Rare Rapid-Aging Disease Progeria Watch Video







Lipp added that there have also been reports of completely "synthetic pomegranate juice" that didn't contain any traces of the real juice.


USP tells ABC News that liquids and ground foods in general are the easiest to tamper with:

  • Olive oil: often diluted with cheaper oils

  • Lemon juice: cheapened with water and sugar

  • Tea: diluted with fillers like lawn grass or fern leaves

  • Spices: like paprika or saffron adulterated with dangerous food colorings that mimic the colors


Milk, honey, coffee and syrup are also listed by the USP as being highly adulterated products.


Also high on the list: seafood. The number one fake being escolar, an oily fish that can cause stomach problems, being mislabeled as white tuna or albacore, frequently found on sushi menus.


National Consumers League did its own testing on lemon juice just this past year and found four different products labeled 100 percent lemon juice were far from pure.


"One had 10 percent lemon juice, it said it had 100 percent, another had 15 percent lemon juice, another...had 25 percent, and the last one had 35 percent lemon juice," Sally Greenberg, Executive Director for the National Consumers League said. "And they were all labeled 100 percent lemon juice."


Greenberg explains there are indications to help consumers pick the faux from the food.


"In a bottle of olive oil if there's a dark bottle, does it have the date that it was harvested?" she said. While other products, such as honey or lemon juice, are more difficult to discern, if the price is "too good to be true" it probably is.


"$5.50, that's pretty cheap for extra virgin olive oil," Greenberg said. "And something that should raise some eyebrows for consumers."


Many of the products USP found to be adulterated are those that would be more expensive or research intensive in its production.
"Pomegranate juice is expensive because there is little juice in a pomegranate," Lipp said.

Vibrating navigator shows cyclists the way



Paul Marks, chief technology correspondent


42-15423733.jpg

(Image: B. S. P. I./Corbis)

Think of it as satnav for your waist. The "vibrobelt", a vibrating belt to help guide cyclists, has proven successful in early tests. It uses vibrating actuators that indicate left, right, backward and forward turn directions, and even tickles the user with coded buzzes that tell them how far they have to go to their destination.





Developed in a masters project by Haska Steltenpohl of the Intelligent Systems Lab at the University of Amsterdam, the Netherlands, alongside supervisor Anders Bouwer, the system aims to give cyclists a "heads-up" navigator, allowing them to keep their eyes on the road after they have chosen their destination on a GPS smartphone. They simply set off and get directional nudges from the vibrators just before each turn.


To see if the vibrotactile navigation compared well with using a standard GPS map on a handlebar-mounted smartphone, 20 volunteers tried both methods on a variety of unfamiliar routes. While all the cyclists reached their destinations successfully, the researchers noted an important difference: when questioned about landmarks they had passed, the vibrobelt users proved much more aware of their surroundings en route than those who were constantly glancing at a GPS screen.


That's a key observation as concerns mount over the appalling death toll among cyclists. The researchers plan to reveal their system and research results at the annual Intelligent User Interfaces conference in Santa Monica, California, in March.


It's not the first time "vibro" navigation has been tried, however. The US military is trialling a system that guides ground troops to targets in a similar fashion.
