Lifelogging captures a real picture of your health



Claire O'Connell, contributor


What difference does it make to your lifestyle if you've got a camera hanging around your neck that is recording every move? A clutch of papers in a special issue of the American Journal of Preventive Medicine aims to answer that question by looking at how so-called lifelogging can influence behaviour.





Much of the research involves Microsoft's SenseCam, which is worn on a lanyard around the neck so it can automatically take hundreds of first-person-view images each day.

One study asked 40 people to wear a SenseCam and an accelerometer to compare how the devices tracked their movements each minute. Perhaps unsurprisingly, the camera gave richer information about context, and it picked up on subtleties such as standing rather than sitting - accelerometers tended to classify both as sedentary behaviour.


Meanwhile, active volunteers - trainee jockeys, Gaelic football and university students - wore SenseCams and kept food diaries for one day. The camera picked up http://www.ajpmonline.org/webfiles/images/journals/amepre/AMEPRE_3672-stamped.pdfon factors such as portion size, forgotten foods, leftovers and brand names, and the pictorial evidence often revealed a higher estimated calorie intake than the wearers themselves reported. This suggests that combining a conventional food diary and a SenseCam could offer a more accurate picture of total energy intake for people who are closely monitoring their diets, such as athletes.


And if a SenseCam is out of reach, a smartphone slung onto a lanyard might do the trick instead. One of the studies asked 47 volunteers to wear a smartphone equipped with lifelogging software that collected data from built-in functions including the accelerometer, compass, camera and GPS. There were some issues with battery life - plus using the phone to track your behaviour means you can't easily use it as a phone. But the authors note that platforms such as smartphones could make camera-wearing more feasible in a wider range of populations.

Wearable cameras have "exciting potential" in health studies, but there are still hurdles to clear before the equipment becomes more widely adopted, says Aiden Doherty from the Centre for Sensor Web Technologies at Dublin City University in Ireland.

Not least is how to process the vast amount of image data produced. "We are working on the challenge of automatically identifying lifestyle behaviour from wearable camera data," he says.

Silver tsunami & dwindling workforce can destabilise economies: Lee Yi Shyan






SINGAPORE: Senior Minister of State for National Development and Trade & Industry Lee Yi-Shyan has painted a sobering picture of an ageing population and shrinking workforce.

Speaking in Parliament on the Population White Paper and Land Use Plan on Wednesday, Mr Lee pointed to the experience of Asian neighbours like Japan and Taiwan as examples of how the silver tsunami and dwindling workforce can destabilise economies.

For example, a city outside Nagoya called Gifu has seen shops along the main street closed for good.

In Hokkaido, in a small town called Yubari, half of the population is above 65 years old.

Mr Lee said Yubari's small working population means a measly tax base.

Four years ago, the city government went bust after owing a debt of US$315 million. The city was later forced to embark on an 18-year austerity drive.

Mr Lee said: "It retrenched half of its civil servants. Public service in the City was badly affected. The public library was gone. Six primary schools merged into one. The General Hospital closed down two thirds of its facilities to save utilities. It also halved its number of ambulances and asked its elderly patients to walk to the hospital by themselves."

The effect of two decades of economic stagnation in Japan, said Mr Lee has led to what is described as "the Waniguchi (crocodile's mouth) effect" - Soaring public expenditure coupled with a drop in tax revenue.

Mr Lee said the huge silver tsunami is destabilising Japan.

He said the country did not manage to raise its working population because it could not build a consensus to allow immigration to boost the workforce.

Similarly in Taiwan, Mr Lee pointed to an article which described the economy as "a small tax revenue country but large welfare state."

Mr Lee said Singapore is not operating in silos.

The world, he said, will continue to move forward, regardless of Singapore's demographic and internal problems.

It is against this larger picture, he said, that Singapore has to define its path forward.

Mr Lee said: "It makes sense for the nation to maintain a sustainable and stable Singaporean population while we are still young, and while external conditions are favourable."

Mr Lee noted there are lessons to be learnt from the experiences of other countries.

The number of elderly citizens in Singapore aged 65 and above will increase considerably from around 340,000 in 2011 to 900,000 by 2030.

Mr Lee cited China's rapidly ageing population to highlight issues which Singapore may face in the future.

He said: "China is beginning to see the "4-2-1" phenomenon: one child having to look after two parents and four grandparents. This inverted pyramid means a heavy burden for the children. When both parents and grandparents are retired, there is also the "aged caring for the aged" phenomenon and this is becoming common in our communities."

Echoing the sentiment, former Cabinet Minister Mah Bow Tan said Singapore cannot afford to lose its edge and become less competitive.

He urged Singaporeans to keep their hearts and minds open.

Mr Mah said: "We have spent a lot of our time looking inwards, talking about our discomforts, our space. We have not asked ourselves how we are going to compete with outside world. How we are going to earn a living to live the good life. It is almost taken from granted that the good life will continue even if growth slows. We expect new infrastructure to be rolled out, even as growth slows. We want more subsidies for health care and housing and let's have less foreign workers and a slower pace of life. Where will the revenue from all this come from?"

Mr Mah, who is MP for Tampines GRC, said government revenue comes mostly from income taxes, consumption taxes and asset taxes, all of which are dependent on economic growth.

He added Singapore needs a bigger population with better educated and trained citizens as well as talented non-residents to supplement the home-grown talent.

LG is hinting that a refresh to its smartphone line is coming.


The company posted an image of a wrapped package on its LG Mobile Facebook page last night. The package has text on top of it reading, "new series will be unveiled." LG's description of the image says that the "surprise" will come with "an unexpected distinction."


LG provided no further details on the "surprise" and didn't say when its product or products might be unveiled. However, Mobile World Congress will be held in Barcelona later this month, and that would be the logical place for LG to unveil its latest creation.


In April, LG is expected to launch the Optimus G Pro, a handset that comes with a 1.7GHz quad-core processors and 5-inch display, in Japan. However, the company has said that it has no plans to launch that handset elsewhere around the world. So whatever it has planned, the smartphones could be something we haven't seen yet.


CNET has contacted LG for comment on the Facebook post. We will update this story when we have more information.

The Real Richard III


It's a question that actors from Laurence Olivier to Kevin Spacey have grappled with: What did Richard III, the villainous protagonist of Shakespeare's famous historical drama, really look and sound like?

In the wake of this week's announcement by the University of Leicester that archaeologists have discovered the 15th-century British king's lost skeleton beneath a parking lot, news continues to unfold that helps flesh out the real Richard III.

The Richard III Society unveiled a 3D reconstruction today of the late king's head and shoulders, based on computer analysis of his skull combined with an artist's interpretation of details from historical portraits. (Related: "Shakespeare's Coined Words Now Common Currency.")

"We received the skull data before DNA analysis confirmed that the remains were Richard III, and we treated it like a forensic case," said Caroline Wilkinson, the University of Dundee facial anthropologist who led the reconstruction project. "We were very pleasantly surprised by the results."

Though Shakespeare describes the king as an "elvish-marked, abortive, rooting hog," the reconstructed Richard has a pleasant, almost feminine face, with youthful skin and thoughtful eyes. His right shoulder is slightly higher than the left, a consequence of scoliosis, but the difference is barely visible, said Wilkinson.

"I think the whole Shakespearean view of him as being sort of monster-like was based more on his personality than his physical features," she reflected.

Look back at 125 years of National Geographic history

People are naturally fascinated by faces, especially of historical figures, said Wilkinson, who has also worked on reconstructions of J.S. Bach, the real Saint Nicholas, the poet Robert Burns, and Cleopatra's sister.

"We make judgments about people all the time from looking at their appearance," she said. "In Richard's case, up to now his image has been quite negative. This offers a new context for considering him from the point of view of his anatomical structure rather than his actions. He had quite an interesting face."

A Voice From the Past

Most people's impression of Richard's personality comes from Shakespeare's play, in which the maligned ruler utters such memorable lines as "Now is the winter of our discontent/Made glorious summer by this son of York," and "A horse! A horse! My kingdom for a horse!"

But how would the real Richard III have expressed himself? Did he have an accent? Was there any sense of personality or passion in his choice of words?

To find out more about the mysterious monarch, Philip Shaw, a historical linguist at University of Leicester's School of English, analyzed the only two known examples of Richard III's own writing. Both are postscripts on letters otherwise composed by secretaries—one in 1469, before Richard became king, and one from 1483, the first year of his brief reign.

Shaw identified a quirk of spelling that suggests that Richard may have spent time in the West Midlands, or perhaps had a tutor who hailed from there.

"I was looking to compare the way he spells things with the way his secretaries spell things, working on the assumption that he would have been schooled to a fairly high level," Shaw explained.

In the 1469 letter, Richard spells the word "will" as "wule," a variation associated with the West Midlands. But Shaw also notes that by 1483, when Richard wrote the second letter's postscript, he had changed his spelling to the more standard "wyll" (the letters 'i' and 'y' were largely interchangeable during that period of Middle English).

"That could suggest something about him brushing up over the years, or moving toward what would have been the educated standard," Shaw said, noting that the handwriting in the second example also appears a bit more polished. "One wonders what sort of practice and teaching he'd had in the interim."

Although it's hard to infer tone of voice from written letters, there is certainly emotion in the words penned by Richard III.

In the 1469 letter, the 17-year-old seeks a loan of 100 pounds from the king's undertreasurer. Although the request is clearly stated in the body of the letter, Richard adds an urgent P.S.: "I pray you that you fail me not now at this time in my great need, as you will that I show you my good lordship in that matter that you labour to me for."

That could either be a veiled threat (If you don't lend me the money, I won't do that thing you asked me to do) or friendly cajoling (Come on, I'm helping you out with something, so help me out with this loan).

"His decision to take the pen himself shows you how important that personal touch must have been in getting people to do something," Shaw said.

The second letter, written to King Richard's chancellor in 1483, also conveys a sense of urgency. He had just learned that the Duke of Buckingham—once a close ally—was leading a rebellion against him.

"He's asking for his Great Seal to be sent to him so that he can use it to give out orders to suppress the rebellion," Shaw said. "He calls the Duke 'the most untrue creature living. You get a sense of how personally let down and betrayed he feels."

Shaw said he hopes his analysis—in combination with the new facial reconstruction—will help humanize Richard III.

"He probably wasn't quite the villain that Shakespeare portrays, though I suspect he was quite ruthless," he said. "But you probably couldn't afford to be a very nice man if you wanted to survive as a king in those days."

Hostage Taker Waged Firefight With SWAT agents













Jimmy Lee Dykes, the man who held a 5-year-old boy hostage for nearly a week in an underground bunker in Alabama, had two homemade explosive devices on his property and engaged in a firefight with SWAT agents before they stormed the bunker and killed him, according to the FBI.


One explosive device was found inside the bunker and another was located in the PVC pipe negotiators used to communicate with Dykes, the FBI said Tuesday night. Both devices were "disrupted," according to the FBI.
The search for hazards is expected to continue through today.


Preliminary investigation reports indicate that Dykes engaged in a firefight with the SWAT agents who made entry, according to the FBI.


Officials were able to insert a high-tech camera into the 6-by-8-foot bunker to monitor Dykes' movements, and they became increasingly concerned that he might act out, a law enforcement source with direct knowledge of the case told ABC News Monday.


FBI special agents were positioned near the entrance of the bunker and negotiators were able to convince Dykes to approach the bunker door. FBI agents used two explosions to gain entry into the bunker. It also appears that Dykes reinforced the bunker against any attempted entry by law enforcement, according to the FBI.


ABC News has learned that Dykes first opened fired on the agents during the bunker raid. Moments later, the agents returned fire, killing Dykes.


The shooting review team continues to gather facts regarding the incident, the FBI said.

The boy, only identified as Ethan, was rescued from the scene by a waiting ambulance. The bunker raid came six days after Dykes boarded a school bus, fatally shot the driver and abducted the boy, who suffered no physical injuries.

"It's all about timing that is why you practice. You practice blowing the door in split seconds, flash bang, shoot before Mr. Dykes would even have an opportunity to react," Brad Garrett, former FBI agent and ABC News consultant, said.


Meanwhile, Ethan is set to celebrate his 6th birthday today, happily reunited with his family.


Ethan's thrilled relatives told "Good Morning America" Tuesday that he seemed "normal as a child could be" after what he went through and has been happily playing with his toy dinosaur.


"He's happy to be home," Ethan's great uncle Berlin Enfinger told "GMA." "He's very excited and he looks good."


"For the first time in almost a week, I woke up this morning to the most beautiful sight...my sweet boy. I can't describe how incredible it is to hold him again," Ethan's' mother wrote in a statement released by the FBI Tuesday.


Ethan is "running around the hospital room, putting sticky notes on everyone that was in there, eating a turkey sandwich and watching SpongeBob," Dale County Schools Superintendent Donny Bynum said at a news conference Tuesday.


When asked about a birthday party for Ethan, Bynum said, "We are still in the planning stages. Our time frame is that we are waiting for Ethan, waiting on that process, but we are going to have it at a school facility, most likely the football stadium at Dale County High School."


He said many "tears of celebration" were shed Monday night when Ethan was reunited with his family.


"If I could, I would do cartwheels all the way down the road," Ethan's aunt Debra Cook told "GMA." "I was ecstatic. Everything just seemed like it was so much clearer. You know, we had all been walking around in a fog and everyone was just excited. There's no words to put how we felt and how relieved we were."


Cook said that Ethan has not yet told them anything about what happened in the bunker and they know very little about Dykes.


What the family does know is that they are overjoyed to have their "little buddy" back.


"He's a special child, 90 miles per hour all the time," Cook said. "[He's] a very, very loving child. When he walks in the room, he just lights it up."

Nobel-winning US energy secretary steps down


































Four years after his appointment as part of President Barack Obama's scientific dream team, US energy secretary Steven Chu is about to step down. How well did he perform in office, and who should fill his shoes? With budget cuts and continued attacks by climate sceptics likely to dog Obama's second term, a politician might be a better choice than another scientist, some observers say.













As the first Nobel laureate appointed to a presidential cabinet, Chu ensured that science informed decisions about clean energy and the funding of new research programmes. He was "good at knowing science is about taking risks", says Marchant Wentworth of the Union of Concerned Scientists in Cambridge, Massachusetts, which aims to bring science to bear on solving the planet's problems.











In 2009, Chu and the Department of Energy (DoE) inherited a number clean-energy research and development initiatives that had been part of the previous administration's stimulus programmes. Among the most interesting programmes that Chu jumpstarted was ARPA-E, a $400 million fund for high-risk, experimental renewable energy research.Movie Camera













A politician might not have seen promise in the nascent programme, and ARPA-E has yet to deliver any game-changing technologies, but Wentworth hopes that Chu's successor will expand the programme. "It's the seed corn of our energy future," he says.











One debacle will cast a shadow over Chu's legacy: the bankruptcy of solar giant Solyndra, a company that had received $535 million in federal loan guarantees from DoE. The backlash, fuelled by a Republican-controlled Congress, quickly spiralled out of control and raised distrust in renewable energy schemes.













Could a more experienced politician have handled the situation better? Eileen Claussen of the Center for Climate and Energy Solutions, a non-profit based in Arlington, Virginia, doubts it. "Getting someone who really believes in the importance of doing this was more important than the political skills," she says, although she also says Chu could have done more to highlight the many successful companies that profited from DoE loans totalling $36 billion.











Different world













But in Obama's second term, vision won't necessarily be as important as management and communication skills, says Claussen. "It's going to be a different world," she says, not least because of serious budget constraints.











DoE's clean-energy budget is likely to be cut by 8 to 10 per cent this year, Wentworth says: a major hit for an already shrunken program. If the next secretary hopes to help Obama with his promises to address climate change, he adds, he or she cannot expect more money to do it with.













And with the animosity against clean-energy programmes unlikely to disappear, says Wentworth, the biggest challenges for Chu's successor will be to aggressively attack myths about the high cost of renewable energy, and to counter lobbying from the fossil-fuel industry.












Energy analyst Scott Sklar, president of the Stella Group, feels that Chu was weak in this area.











For the next secretary to build support for renewable energy programmes, "they need to articulate why what they're doing is important", he says. The next secretary will also need to tackle problems associated with energy generation, such as massive water use by power plants in the midst of a drought, and the air and water pollution they cause.

MDA introduces new scholarship for film-makers






SINGAPORE: The Media Development Authority (MDA) has introduced a special film category for its Media Education Scheme (MES).

The MES (Film) scholarship is tailored for screenwriters, directors and film-makers, who tend to operate on a freelance basis.

On top of full scholarship and an annual living allowance, MES (Film) scholars will be assigned to mentors who will coach, guide and provide contacts and opportunities to the recipient.

Unlike other MES scholars, film scholars will not be offered full-time employment upon graduation, but will be expected to commit to two years of service under the mentorship of their assigned film-makers.

In a written parliamentary reply to Nominated MP Janice Koh, Minister for Communications and Information Dr Yaacob Ibrahim said the new scheme is the result of consultation between MDA and the film industry, following feedback that the MES may not cater to the needs of the film industry.

The MES was revised in 2012 to include job placements for scholars with the aim of matching their talents with media companies' needs for specific skill sets.

MES scholars are offered internship and training opportunities, as well as an employment bond of three to five years upon graduation with their companies, which include MediaCorp and Singapore Press Holdings.

BlackBerry taps Trend Micro to scan apps for malware



BlackBerry is counting on Trend Micro to help ensure the security of its third-party mobile apps.


Like other app store vendors, BlackBerry already scans mobile apps for malware to protect BlackBerry World customers. But now the company will add Trend Micro's Mobile Application Reputation Service to take that protection a few steps further.


Both current and new apps submitted to BlackBerry World will be scanned by Trend Micro's cloud-based service to hunt for malware. The security vendor's Mobile Application Reputation Service uses its own proprietary system to analyze mobile apps for potential threats.


"BlackBerry is working with Trend Micro to implement a more robust approach for addressing privacy and security concerns related to third-party applications," Adrian Stone, director for BlackBerry Security Response and Threat Analysis, said in a statement. "By incorporating Trend Micro's advanced mobile scanning and detection capabilities with our own internal, proprietary application analyzing system, we can provide another layer of protection and assurance for BlackBerry customers."



Last week, BlackBerry unveiled its BB10 mobile operating system and the first two smartphones to run the new OS.


But the company knows that apps are key if it expects users to gravitate toward its mobile devices.


Toward that end, BlackBerry has been trying to drum up interest among app developers and customers alike.


The company recently sponsored a "Portathon" event designed to convince developers to port their existing apps over to BB10. BlackBerry also just lowered the price tiers for its mobile apps and updated BlackBerry World with more movies, music, and other content.

Space Pictures This Week: A Space Monkey, Printing a Moon Base

Illustration courtesy Foster and Partners/ESA

The European Space Agency (ESA) announced January 31 that it is looking into building a moon base (pictured in an artist's conception) using a technique called 3-D printing.

It probably won't be as easy as whipping out a printer, hooking it to a computer, and pressing "print," but using lunar soils as the basis for actual building blocks could be a possibility.

"Terrestrial 3-D printing technology has produced entire structures," said Laurent Pambaguian, head of the project for ESA, in a statement.

On Earth, 3-D printing, also known as additive manufacturing, produces a three-dimensional object from a digital file. The computer takes cross-sectional slices of the structure to be printed and sends it to the 3-D printer. The printer bonds liquid or powder materials in the shape of each slice, gradually building up the structure. (Watch how future astronauts could print tools in space.)

The ESA and its industrial partners have already manufactured a 1.7 ton (1.5 tonne) honeycombed building block to demonstrate what future construction materials would look like.

Boy Rescued in Ala. Standoff 'Laughing, Joking'













The 5-year-old boy held hostage in a nearly week-long standoff in Alabama is in good spirits and apparently unharmed after being reunited with his family at a hospital, according to his family and law enforcement officials.


The boy, identified only as Ethan, was rescued by the FBI Monday afternoon after they rushed the underground bunker where suspect Jimmy Lee Dykes, 65, was holding him. Dykes was killed in the raid and the boy was taken away from the bunker in an ambulance.


Who Is Jimmy Lee Dykes?


Officials have not yet provided any further details on the raid, citing the ongoing investigation.


"I've been to the hospital," FBI Special Agent Steve Richardson told reporters Monday night. "I visited with Ethan. He is doing fine. He's laughing, joking, playing, eating, the things that you would expect a normal 5- to 6-year-old young man to do. He's very brave, he's very lucky, and the success story is that he's out safe and doing great."


Ethan is expected to be released from the hospital later today and head home where he will be greeted by birthday cards from his friends at school. Ethan will celebrate his 6th birthday Wednesday.

Officials were able to insert a high-tech camera into the 6-by-8-foot bunker to monitor Dykes' movements, and they became increasingly concerned that he might act out, a law enforcement source with direct knowledge told ABC News Monday. FBI special agents were positioned near the entrance of the bunker and used an explosive charge to gain access and neutralize Dykes.


"Within the past 24 hours, negotiations deteriorated and Mr. Dykes was observed holding a gun," the FBI's Richardson said. "At this point, the FBI agents, fearing the child was in imminent danger, entered the bunker and rescued the child."


Richardson said it "got tough to negotiate and communicate" with Dykes, but declined to give any specifics.


After the raid was complete, FBI bomb technicians checked the property for improvised explosive devices, the FBI said in a written statement Monday afternoon.


The FBI had created a mock bunker near the site and had been using it to train agents for different scenarios to get Ethan out, sources told ABC News.


Former FBI special agent and ABC News consultant Brad Garrett said rescue operators in this case had a delicate balance.


"You have to take into consideration if you're going to go in that room and go after Mr. Dykes, you have to be extremely careful because any sort of device you might use against him, could obviously harm Ethan because he's right there," he said.


Still, Monday's raid was not the ending police had sought as they spent days negotiating with the decorated Vietnam veteran through a ventilation shaft. The plastic PVC pipe was also used to send the child comfort items, including a red Hot Wheels car, coloring books, cheese crackers, potato chips and medicine.


State Sen. Harri Anne Smith said Ethan's mother asked police a few days ago not to kill Dykes.


"She put her hand on the officer's heart and said, 'Sir, don't hurt him. He's sick,'" Smith said Monday.


Taylor Hodges, pastor of the Midland City Baptist Church, said, "Many people here don't keep their doors locked. Things are going to change, especially for our school system."


The outcome of the situation drew praise from the White House.
