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.

At Mali's request, France launched the offensive against militants in its former colony last month. The ground-and-air campaign has sent Islamist fighters who had seized the northern region fleeing into the vast desert.


French President Francois Hollande visited Timbuktu last week, just days after French forces had freed the fabled city from Islamist militants.

French-led troops now control Timbuktu and the city of Gao, along with a swath in between the two that was an Islamist stronghold for almost a year.


Troops are working to secure Kindal, the last major city under the grip of militants.


Over the past two days, sandstorms have hampered operations across the country.


Islamic extremists carved out a large portion of the north last year after a chaotic military coup.


They banned music, smoking, drinking and watching sports on television, and destroyed historic tombs and shrines in the region. World leaders feared that the al Qaeda-linked militants would turn the area into a terrorist haven.


France says it has 4,000 soldiers in Mali. Its troops are fighting alongside nearly 3,800 African soldiers, it said, a number expected to go up.

USPS to announce Saturday service cuts in effort to slash costs

(CBS News) Get ready for some big changes in your mail service. After losing $16 billion last year, the postmaster general will make announce Wednesday that the Postal Service intends to halt Saturday delivery of first-class mail by this summer, Aug. 1, CBS News has learned. That means most mailers, letters and catalogs would not arrive on Saturdays, ending a 150-year tradition.

The plan to shrink delivery from six days a week to five would only affect first-class mail, while packages, mail-order medicines, priority and express mail would still get delivered on Saturdays.

.

Sen. Tom Coburn, R-Okla., says the move will save the struggling postal service $2 billion a year. "It's a proper business decision and (in the) long run, good for the Postal Service and good for Americans."

The Postal Service has lost $41 billion dollars over the past six years as more and more Americans turned to private shippers, email, and online banking.

To save money, the Postal Service slashed hours of service at about half the nation's 26,000 post offices and trimmed its workforce by 35 percent.

But it wasn't enough. David Walker, a former government watchdog, is part of a panel looking at possible postal reforms. Walker told CBS News the new measure "won't come close to solving the postal service's problem. It's got to look at more fundamental changes in its infrastructure, its compensation costs, its retirement obligations, and also what it does and who does its business."

But there's just so much the Postal Service can do without congressional approval. Despite years of begging by postmasters general, Congress never passed a reform bill that would have given the Postal Service more flexibility to modernize and streamline its service.

Asked whether the Postal Service is making this announcement because they're trying to force Congress to act, Coburn said, "No, I don't think so at all. Look, they're in survival mode. You're not going to have any post office. I mean, here's the alternative: They're losing $25 million dollars a day. A day. They have to do something."

Technically, the Postal Service is not allowed to its reduce service unless Congress changes the law, but lawyers for the Postal Service think that they have figured out a way around this. Even President Barack Obama has endorsed the plan to cut Saturday service. It was part of his deficit reduction plan last year.

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.

Ethan 'doing fine' after Alabama standoff ends






STORY HIGHLIGHTS


  • Rescued child is in good spirits at hospital, authorities say

  • FBI says boy was rescued after negotiators felt he was in danger

  • Witness said he heard explosion followed by gunshots

  • A family member says Ethan will stay overnight in the hospital




Midland City, Alabama (CNN) -- At least Ethan is safe.


That is the sentiment many were expressing in Midland City, Alabama, and beyond. But what comes next for this little boy about to turn six could be complicated.


How does a five-year-old heal from this ordeal? How does a youngster go on after witnessing his bus driver shot to death, after being dragged to an underground bunker by a gun-toting stranger? How will he deal with what he experienced the six days he languished in that hole and what he saw during the explosive rescue Monday that left his captor dead?


"It's very hard to tell how he's going to do," said Louis Krouse, a psychiatrist at Chicago's Rush Medical Center. "On the one hand, he might get right back to his routine and do absolutely fine. But on the other hand, the anxieties, the trauma, what we call an acute stress disorder even post traumatic stress symptoms can occur."


Just as it has been for most of this saga, authorities, at a late night news conference Monday, released few details the boy's rescue.










Ethan was taken to a hospital, said FBI Special Agent in Charge Steve Richardson, where he was in a private area with heavy security.


"He is doing fine," Richardson said, adding that he visited the boy. "He's laughing, joking, playing, eating."


Dale County Sheriff Wally Olson added no new details about Ethan's rescue but thanked the contingent of federal and state law enforcement that helped.


When asked if the boy saw his abductor, 65-year-old Jimmy Lee Dykes, killed during the rescue operation, Olson replied "He's a very special child. He's been through a lot, he's endured a lot."


Support crucial for kids after trauma


The Rescue


Last Tuesday, police said, Dykes boarded a Dale County school bus and demanded the driver hand over two children.


The driver, Charles Albert Poland Jr., refused, blocking access to the bus's narrow aisle as at least 21 children escaped out of the back emergency door, authorities said.


The gunman killed Poland, then grabbed the kindergartner before barricading himself and the boy inside a nearby bunker he had built on his southeast Alabama land. In the ensuing days, officials said little about what was going on in the bunker or in their strategy, or what -- if anything -- Dykes wanted.


It became very difficult to deal with or even communicate with Dykes over the past day, Olson said. Also Dykes was observed holding a gun.


Believing the child to be in imminent danger, an FBI team entered the bunker at 3:12 p.m. CT (4:12 p.m. ET) and rescued the boy.


One neighbor said he was outside when he was startled by the sound of an explosion.


"I heard a big boom and then ... I believe I heard rifle shots," said Bryon Martin, who owns a home near the bunker where the boy had been held since Tuesday.


It was a loud noise that "made me jump off the ground," he said.


Authorities wouldn't say whether the blast was set off as a diversionary tactic or whether Dykes had planted explosives around the bunker.


At one point Monday, Olson told reporters, "Based on our discussions with Mr. Dykes, he feels like he has a story that's important to him, although it's very complex."


The sheriff did not elaborate.


When terrible things happen: Helping children heal


The Recovery


Ethan suffers from Asperger's syndrome and attention deficit disorder, state Rep. Steve Clouse said during the week. This could affect the boy as he tries to deal with the what he experienced, said Krouse.


"A typical 5-year-old child would find this frightening. But with a child with Asperger's, which is a form of autism," Krouse said, "we have to make sure that we get him back to his normal routines and that if the anxiety levels are overwhelming, to treat those."


Someone who knows all too well what Ethan may go through is Katie Beers, who as a 10-year-old was held underground in a concrete bunker for two weeks by a New York man.


"I am ecstatic that Ethan has been retrieved safe and sound," said Beers, who recently released a book about her abduction. "As for my ordeal, I just keep thinking about the effects of it being deprived sunlight, nutritious food and human contact. And how much I wanted to have a nutritious meal, see my family."


Beers says she still feels the affects of her kidnapping even though she is 30 now and has her own children.


"The major issue that I have is control issues with my kids and finances," she said. "I don't like my kids being out of my sight for more than two seconds. And I think that that might get worse as they get older."


For now, those who have seen Ethan say he was doing well and was in good spirits.


He was scheduled to stay overnight at the hospital, the boy's uncle told a crowd gathered at a prayer vigil Monday night.


Guiding children through grief and loss

Signs of runaway heat seen in Dreamliner batteries

TOKYO An investigation into a lithium ion battery that overheated on a Boeing 787 flight in Japan last month found evidence of the same type of "thermal runaway" seen in a similar incident in Boston, officials said Tuesday.

The Japan Transportation Safety Board said that CAT scans and other analysis found damage to all eight cells in the battery that overheated on the All Nippon Airways 787 on Jan. 16, which prompted an emergency landing and probes by both U.S. and Japanese aviation safety regulators.

They also found signs of short-circuiting and "thermal runaway," a chemical reaction in which rising temperature causes progressively hotter temperatures. U.S. investigators found similar evidence in the battery that caught fire last month on a Japan Airlines 787 parked in Boston.

Photos distributed by the Japanese investigators show severe charring of six of the eight cells in the ANA 787's battery and a frayed and broken earthing wire — meant to minimize the risk of electric shock.

All 50 Boeing 787s in operation are grounded as regulators and Boeing investigate the problem. The Japanese probe is focusing on flight data records and on the charger and other electrical systems connected to the damaged battery.

Lithium ion batteries are more susceptible to catching fire when they overheat or to short-circuit than other types of batteries. Boeing built in safeguards to gain safety certification for use of the relatively light and powerful batteries to power various electrical systems on the 787, the world's first airliner made mostly from lightweight composite materials.

Investigators earlier said they found no evidence of quality problems with production of the 787's batteries by Kyoto, Japan-based, GS Yuasa, whose own aerospace ambitions are on the line.

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.

Bug protects itself by turning its environment to gold









































Mythical King Midas was ultimately doomed because everything he touched turned to gold. Now, the reverse has been found in bacteria that owe their survival to a natural Midas touch.












Delftia acidovorans lives in sticky biofilms that form on top of gold deposits, but exposure to dissolved gold ions can kill it. That's because although metallic gold is unreactive, the ions are toxic.












To protect itself, the bacterium has evolved a chemical that detoxifies gold ions by turning them into harmless gold nanoparticles. These accumulate safely outside the bacterial cells.












"This could have potential for gold extraction," says Nathan Magarvey of McMaster University in Hamilton, Ontario, who led the team that uncovered the bugs' protective trick. "You could use the bug, or the molecules they secrete."












He says the discovery could be used to dissolve gold out of water carrying it, or to design sensors that would identify gold-rich streams and rivers.












The protective chemical is a protein dubbed delftibactin A. The bugs secrete it into the surroundings when they sense gold ions, and it chemically changes the ions into particles of gold 25 to 50 nanometres across. The particles accumulate wherever the bugs grow, creating patches of gold.











Deep purple gold













But don't go scanning streams for golden shimmers: the nanoparticle patches do not reflect light in the same way as bigger chunks of the metal – giving them a deep purple colour.












When Magarvey deliberately snipped out the gene that makes delftibactin A, the bacteria died or struggled to survive exposure to gold chloride. Adding the protein to the petri dish rescued them.











The bacterium Magarvey investigated is one of two species that thrive on gold, both identified a decade or so ago by Frank Reith of the University of Adelaide in Australia. In 2009 Reith discovered that the other species, Cupriavidus metallidurans, survives using the slightly riskier strategy of changing gold ions into gold inside its cells.













"If delftibactin is selective for gold, it might be useful for gold recovery or as a biosensor," says Reith. "But how much dissolved gold is out there is difficult to say."
