Retail sales dip 1% on-year in Oct

SINGAPORE: Retail sales in Singapore dipped one per cent on-year in October as a result of lower sales of motor vehicles, according to the Department of Statistics (DOS).

Excluding motor vehicles, DOS said retail sales rose 1.3 per cent on-year.

Compared to the previous year, retail sales of motor vehicles decreased 8.5 per cent in October 2012.

Sales of optical goods and books, watches and jewellery, recreational goods and furniture and household equipment all declined in October at between 0.7 per cent and 2.9 per cent.

In contrast, sales of telecommunications products and computers recorded an 8.0 per cent increase on-year in October.

Meanwhile, retail sales of medical goods and toiletries, supermarkets, petrol service stations, wearing apparel and footwear and provision and sundry shops also increased by between 1.2 per cent and 6.6 per cent in October over the same period last year.

In the food and beverage services segment, retail sales rose 3.1 per cent in October 2012 compared to October 2011.

On a month-on-month basis, DOS said retail sales increased 0.6 per cent in October 2012.

Apple pursues iPad Mini with better display, say 'sources'

Consumers expect Apple to upgrade the current iPad Mini to a Retina class display, according to recent comments from NPD DisplaySearch.

CNET)

The
iPad Mini has been an exception to Apple's Retina obsession. But fresh gossip from Asia-based industry sources indicates Apple wants to rectify this.

An upcoming version of the iPad Mini will "focus on enhancing the...display resolution," according to a report at Taipei-based Digitimes. The report cited "backlighting industry" sources.

That's as far as the gossip goes, however. No leaked specs or rumors about display makers ramping up production of new displays.

That said, it jibes with what display analysts have been saying over the last few weeks and previous rumors that claimed display maker AUO is working on a 2,048x1,536 pixel resolution display for the next iPad Mini.

"I think that's highly likely for the progression of that product," Vinita Jakhanwal, a display analyst IHS iSuppli, told CNET last month. "And also the fact that they have a whole ecosystem of apps that have been developed for the [Retina]
iPad 3 and iPad 4."

Whether it's feasible for Apple and its display partners to pursue this, is the question. For example, if Apple did a Retina version of the Mini it would be approximately 300 pixels per inch. That's really hard to manufacture and hasn't been done yet for the 7.9-inch class display that Apple uses.

That said, Amazon has come close. The larger Amazon Kindle Fire HD has an 8.9-inch display boasting 254 pixels per inch. By Apple's own definition of pixel density, that's Retina resolution.

Amazon has managed to squeeze a Retina-class display into an 8.9-inch tablet and priced it at $299. In that sense, they have beat Apple at its own game.

Global Checkup: Most People Living Longer, But Sicker

If the world's entire population went in for a collective checkup, would the doctor's prognosis be good or bad? Both, according to new studies published in The Lancet medical journal.

The vast collaborative effort, called the Global Burden of Diseases, Injuries, and Risk Factors Study 2010, includes papers by nearly 500 authors in 50 countries. Spanning four decades of data, it represents the most comprehensive analysis ever undertaken of health problems around the world.

It reveals that, globally, we're living longer but coping with more illness as adults. In 1990, "childhood underweight"—a condition associated with malnutrition, measles, malaria, and other infectious diseases—was the world's biggest health problem. Now the top causes of global disease are adult ailments: high blood pressure (associated with 9.4 million deaths in 2010), tobacco smoking (6.2 million), and alcohol use (4.9 million).

First, the good news:

We're living longer. Average life expectancy has risen globally since 1970 and has increased in all but eight of the world's countries within the past decade.

Both men and women are gaining years. From 1970 to 2010, the average lifespan rose from 56.4 years to 67.5 years for men, and from 61.2 years to 73.3 years for women.

Efforts to combat childhood diseases and malnutrition have been very successful. Deaths in children under five years old declined almost 60 percent in the past four decades.

Developing countries have made huge strides in public health. In the Maldives, Bangladesh, Bhutan, Iran, and Peru, life expectancy has increased by more than 20 years since 1970. Within the past two decades, gains of 12 to 15 years have occurred in Angola, Ethiopia, Niger, and Rwanda, an indication of successful strategies for curbing HIV, malaria, and nutritional deficiencies.

We're beating many communicable diseases. Thanks to improvements in sanitation and vaccination, the death rate for diarrheal diseases, lower respiratory infections, meningitis, and other common infectious diseases has dropped by 42 percent since 1990.

And the bad:

Non-infectious diseases are on the rise, accounting for two of every three deaths globally in 2010. Heart disease and stroke are the primary culprits.

Young adults aren't doing as well as others. Deaths in the 15 to 49 age bracket have increased globally in the past 20 years. The reasons vary by region, but diabetes, smoking, alcohol, HIV/AIDS, and malaria all play a role.

The HIV/AIDS epidemic is taking a toll in sub-Saharan Africa. Life expectancy has declined overall by one to seven years in Zimbabwe and Lesotho, and young adult deaths have surged by more than 500 percent since 1970 in South Africa, Botswana, Zambia, and Zimbabwe.

We drink too much. Alcohol overconsumption is a growing problem in the developed world, especially in Eastern Europe, where it accounts for almost a quarter of the total disease burden. Worldwide, it has become the top risk factor for people ages 15 to 49.

We eat too much, and not the right things. Deaths attributable to obesity are on the rise, with 3.4 million in 2010 compared to 2 million in 1990. Similarly, deaths attributable to dietary risk factors and physical inactivity have increased by 50 percent (4 million) in the past 20 years. Overall, we're consuming too much sodium, trans fat, processed meat, and sugar-sweetened beverages, and not enough fruits, vegetables, whole grains, nuts, fiber, calcium, and omega-3 fatty acids.

Smoking is a lingering problem. Tobacco smoking, including second-hand smoke, is still the top risk factor for disease in North America and Western Europe, just as it was in 1990. Globally, it's risen in rank from the third to second leading cause of disease.

Health-Exchange Deadline Looms

All of the Affordable Care Act, also known as "Obamacare," doesn't go into effect until 2014, but states are required to set up their own health care exchanges or leave it to the federal government to step in by next year. The deadline for the governors' decisions is Friday.

The health insurance exchanges are one of the key stipulations of the new health care law. They will offer consumers an Internet-based marketplace for purchasing private health insurance plans.

But the president's signature health care plan has become so fraught with politics that whether governors agreed to set up the exchanges has fallen mostly along party lines.

Such partisanship is largely symbolic because if a state opts not to set up the exchange, the Department of Health and Human Services will do it for them as part of the federal program. That would not likely be well-received by Republican governors, either, but the law forces each state's chief executive to make a decision one way or the other.

Here's what it looks like in all 50 states and the District of Columbia:

20 states that have opted out -- N.J., S.C., La., Wis., Ohio, Maine, Ala., Alaska, Ariz., Ga., Pa., Kan., Neb., N.H., N.D., Okla., S.D., Tenn., Texas and Wyo.

Several Republican governors have said they will not set up the exchanges, including Chris Christie (N.J.), Nikki Haley (S.C.), Bobby Jindal (La.), Scott Walker (Wis.), John Kasich (Ohio), Paul LePage (Maine), Robert Bentley (Ala.), Sean Parnell (Ark.), Jan Brewer (Ariz.), Nathan Deal (Ga.), Tom Corbett (Pa.), Sam Brownback (Kan.), Dave Heineman (Neb.), John Lynch (N.H.), Jack Dalrymple (N.D.), Mary Fallin (Okla.), Dennis Daugaard (S.D.), Bill Haslam (Tenn.), Rick Perry (Texas), and Matt Mead (Wyo.).

3 States Out, but a Little More Complicated -- Mont., Ind. and Mo.

The Montana outgoing and incoming governors are both Democrats, but the Republican state legislature rejected the Democratic state auditor's request to start setting up a state exchange. So a federal exchange will be set up in Montana as well.

The Indiana outgoing and incoming governors are both Republicans and outgoing Gov. Mitch Daniels deferred the decision to governor-elect and U.S. Rep. Mike Pence, who said his preference is not to set up a state health care exchange, paving the way for the feds to come in too.

In Missouri, Gov. Jay Nixon is a Democrat, but Prop E passed on Nov. 6, which barred his administration from creating a state-based exchange without a public vote or the approval of the state legislature. After the election, he sent a letter to the Department of Health and Human Services saying he would be unable to set up a state-based exchange, meaning the federal government would have to set up its own.

1 State Waiting for the White House -- Utah

Utah already has a state exchange set up, a Web-based tool where small-business employees can shop and compare health insurance with contributions from their employee. In a letter Republican Gov. Gary Herbert sent to the White House Tuesday, he asked for its exchange, called Avenue H, to be approved as a state-based exchange under the Affordable Care Act as long as state officials can open it to individuals and larger businesses.

Norm Thurston, the state's health reform implementation coordinator, says authorities there "haven't received an official response" from the White House, but "we anticipate getting one soon."

There are some sticking points that don't comply with the exchanges envisioned by the Affordable Care Act and Utah would like to keep it that way.

First results from James Cameron's trip to the abyss

IT'S not Pandora, but the Mariana trench holds life just as strange as that in James Cameron's film Avatar. And most is unknown to us, despite the film-maker's 11-kilometre descent into Earth's deepest point in a titanium sphere.

Cameron and scientists on the team presented early findings at the American Geophysical Union's meeting in San Francisco last week. They told of microbial mats growing at the edge of hydrothermal vents on rocks that appeared to be undergoing serpentinisation - where seawater reacts with the mineral olivine to release hydrogen and methane: food for the microbes. The first life on Earth may have appeared at a similar vent, as serpentinisation provides all the raw materials necessary for metabolism.

Cameron urged further trips into unexplored ocean trenches: "Saying I made any dent would be like dropping out of an airplane at night onto a wheat field in Nebraska, walking for 2 kilometres, and saying I explored America."

S. Korea seeks to recover N. Korea rocket debris

SEOUL: South Korea's navy has launched a salvage operation in the Yellow Sea to retrieve debris from North Korea's long-range rocket launch, military officials said Thursday.

The first stage of the North's Unha-3 rocket launched on Wednesday fell in the sea off the Korean peninsula, while the second splashed down east of the Philippines.

"Our navy discovered what appeared to be a part from the first stage of North Korea's rocket in the Yellow Sea Wednesday afternoon," a defence ministry spokesman told AFP.

"A salvage operation is now under way to retrieve it," he said, declining to give details.

The chunk of the debris was found on the sea bed, some 160 kilometers (100 miles) west of the southwestern port of Gunsan, Yonhap news agency said, at a depth of around 80 meters (260 feet).

Before its last rocket launch attempt in April -- which ended in failure -- North Korea had warned both Japan and South Korea that any effort to salvage debris from the rocket would be considered an "act of war".

The warning was not repeated before Wednesday's launch.

Pyongyang said its latest launch was a purely scientific mission aimed at placing a polar-orbiting earth observation satellite in space.

Most of the world saw it as a disguised ballistic missile test that violates UN resolutions imposed after the North's nuclear tests in 2006 and 2009.

The UN Security Council has condemned the launch and warned of possible measures over what the US called a "highly provocative" act.

Google, Microsoft 'challenged' vs. Apple, says Goldman Sachs

CNET)

Google and Microsoft will struggle to vend off Apple's smartphone-tablet juggernaut, according to a recent study by Goldman Sachs.

Titled "Clash of the titans," the 75-page study depicts Google and Microsoft as "challenged" in their bids to compete with Apple.

Some salient points made by Goldman Sachs, which based many of their findings on internal survey results:

• Well positioned v. challenged: In the "context of platform adoption," companies that are defined as "well positioned" include Apple, Facebook, Samsung. Amazon is "straddling the line." Google and Microsoft are "challenged" in platform adoption.
  
• Google: "Tablet share loss leads to smartphone share defection."
  Android
  tablet share (excluding the
  Kindle Fire) will drop to 21 percent next year from 33 percent this year. Android smartphone share
  will decline next year to 53 percent from 55 percent this year. "We ultimately see Google as trying to find a way to stay just as relevant in the new compute paradigm as it was during Web 1.0 and 2.0."
  
• Microsoft: Market share of "total consumer compute" has fallen from 93 percent in 2000 to an expected 20 percent in 2012 due to smartphones and, more recently, tablets. Though Windows Phone 8 and Windows 8 tablets will help the company "reclaim some share in coming years," the consumer PC market will be flat in 2013 and Microsoft "would have to sell roughly 5 Windows Phones or roughly two Windows 8 RT tablets to offset the loss of one traditional Windows PC sale."
  

Apple comes across in the report as a technological juggernaut that will be hard to stop.

Spending on complements (products or services that sit on top of the platform) is rising and Apple continues to lead, Goldman said.

"We believe loyalty to the company's ecosystem is only increasing and this should translate into continued growth going forward...In particular, we see the potential for Apple to capture additional growth as existing iOS users move to multiple device ownership."

With new devices such as the iPad mini and lower priced iPhones, Apple's market share in phones "has room to rise much further, and that its dominant tablet market share appears to be more resilient than most expect."

Hubble Discovers Oldest Known Galaxy

The Hubble space telescope has discovered seven primitive galaxies formed in the earliest days of the cosmos, including one believed to be the oldest ever detected.

The discovery, announced Wednesday, is part of the Hubble Ultra Deep Field campaign to determine how and when galaxies first assembled following the Big Bang.

"This 'cosmic dawn' was not a single, dramatic event," said astrophysicist Richard Ellis with the California Institute of Technology in Pasadena. Rather, galaxies appear to have been formed over hundreds of millions of years.

Ellis led a team that used Hubble to look at one small section of the sky for a hundred hours. The grainy images of faint galaxies include one researchers determined to be from a period 380 million years after the onset of the universe—the closest in time to the Big Bang ever observed.

The cosmos is about 13.7 billion years old, so the newly discovered galaxy was present when the universe was 4 percent of its current age. The other six galaxies were sending out light from between 380 million and 600 million years after the Big Bang. (See pictures of "Hubble's Top Ten Discoveries.")

Baby Pictures

The images are "like the first ultrasounds of [an] infant," said Abraham Loeb, a specialist in the early cosmos at Harvard University. "These are the building blocks of the galaxies we now have."

These early galaxies were a thousand times denser than galaxies are now and were much closer together as well, Ellis said. But they were also less luminous than later galaxies.

The team used a set of four filters to analyze the near infrared wavelengths captured by Hubble Wide Field Camera 3, and estimated the galaxies' distances from Earth by studying their colors. At a NASA teleconference, team members said they had pushed Hubble's detection capabilities about as far as they could go and would most likely not be able to identify galaxies from further back in time until the James Webb Space Telescope launches toward the end of the decade. (Learn about the Hubble telescope.)

"Although we may have reached back as far as Hubble will see, Hubble has set the stage for Webb," said team member Anton Koekemoer of the Space Telescope Science Institute in Baltimore. "Our work indicates there is a rich field of even earlier galaxies that Webb will be able to study."

N. Korean Missile Hits Target of Alarming the World

North Korea's successful launch of an intercontinental ballistic missile hit its target: it bolstered the standing of its young tyrant Kim Jong Un and raised the specter of being able to eventually strike the U.S. with a nuclear weapon.

The pride in the success of the launch -- after several failures -- is a huge boost for Kim Jong Un, 29, who took power one year ago. He has been trying to cement his authority and win the hearts of the people with soft social and economic reforms, like allowing women to wear pants or more small businesses to operate based on profit.

But the rocket launch was on a different scale. A North Korean female announcer in a pink and dark grey national costume excitedly read an announcement of the missile's success and national TV aired interviews with people jumping and cheering on the news.

There had been reservations within and outside of North Korea when Kim Jong Un took power after his father's death on Dec. 17 last year as to whether the young Kim could lead a nuclear state. Looking determined at his first official appearance earlier this year, he had pledged to fulfill the legacy of his father Kim Jong Il to become a "self-sufficient strong nation" with space rocket technology.

The missile is believed to have a range of 6,212 miles, enough distance to reach the west coast of the United States. Its existence, along with a small North Korean nuclear arsenal, is an alarming possibility for many.

PHOTOS: An Inside Look At North Korea

North Korea, however, says it was simply putting a satellite in orbit.

"Picking on our launch (and not others) accusing that ours is a long-range missile and a provocative act causing instability comes from seeing us from a hostile point of view," said North Korea's foreign ministry in an official statement. "We do not want this to be overblown into something that none of us intended to be and hope all related nations act with reason and calmness."

But North Korean denials carry little credibility.

This evidence that North Korea has mastered the long-range missile technology does not mean there will be an imminent nuclear threat.

"They haven't figured out how to weaponize a nuclear (bomb) that will fit in a missile, nor do they have accurate guidance at long ranges," said Stephen Ganyard, ABC News consultant and former deputy assistant secretary of state.

Another crucial technology North Korea is yet to achieve is a proper heat shielding required to protect the warhead while re-entering the earth's atmosphere.

"This is a big leap for Pyongyang. They have been a threat with potential capability. But now a new era begins as a threat with possible capability," said Hwee-Rhak Park, professor of political leadership at Kookmin University in Seoul.

There was obvious alarm, however, as the international community condemned the launch, as North Korea is banned from developing nuclear and missile-related technology under U.N. resolutions.

South Korean President Lee Myung-Bak convened an emergency national security meeting. Japan's envoy to the United Nations called for consultations on the launch within the U.N. Security Council. Russian Foreign Ministry said it "has caused us deep regret," and even China "expressed regret," a significant notch up in condemnation from previous statements on North Korea, its traditional ally.

That international attention, analysts in Seoul say, is exactly what North Korea wanted.
