Earth may be crashing through dark matter walls

Earth is constantly crashing through huge walls of dark matter, and we already have the tools to detect them. That's the conclusion of physicists who say the universe may be filled with a patchwork quilt of force fields created shortly after the big bang.

Observations of how mass clumps in space suggest that about 86 per cent of all matter is invisible dark matter, which interacts with ordinary matter mainly through gravity. The most popular theory is that dark matter is made of weakly interacting massive particles.

WIMPs should also interact with ordinary matter via the weak nuclear force, and their presence should have slight but measurable effects. However, years of searches for WIMPs have been coming up empty.

"So far nothing is found, and I feel like it's time to broaden the scope of our search," says Maxim Pospelov of the University of Victoria in Canada. "What we propose is to look for some other signatures."

Bubbly cosmos

Pospelov and colleagues have been examining a theory that at least some of the universe's dark matter is tied up in structures called domain walls, akin to the boundaries between tightly packed bubbles. The idea is that the hot early universe was full of an exotic force field that varied randomly. As the universe expanded and cooled, the field froze, leaving a patchwork of domains, each with its own distinct value for the field.

Having different fields sit next to each other requires energy to be stored within the domain walls. Mass and energy are interchangeable, so on a large scale a network of domain walls can look like concentrations of mass – that is, like dark matter, says Pospelov.

If the grid of domain walls is packed tightly enough – say, if the width of the domains is several hundred times the distance between Earth and the sun – Earth should pass through a domain wall once every few years. "As a human, you wouldn't feel a thing," says Pospelov. "You will go through the wall without noticing." But magnetometers – devices that, as the name suggests, measure magnetic fields – could detect the walls, say Pospelov and colleagues in a new study. Although the field inside a domain would not affect a magnetometer, the device would sense the change when Earth passes through a domain wall.

Dark matter walls have not been detected yet because anyone using a single magnetometer would find the readings swamped by noise, Pospelov says. "You'd never be able to say if it's because the Earth went through a bizarre magnetic field or if a grad student dropped their iPhone or something," he says.

Network needed

Finding the walls will require a network of at least five detectors spread around the world, Pospelov suggests. Colleagues in Poland and California have already built one magnetometer each and have shown that they are sensitive enough for the scheme to work.

Domain walls wouldn't account for all the dark matter in the universe, but they could explain why finding particles of the stuff has been such a challenge, says Pospelov.

If domain walls are found, the news might come as a relief to physicists still waiting for WIMPs to show up. Earlier this month, for instance, a team working with a detector in Russia that has been running for more than 24 years announced that they have yet to see any sign of these dark matter candidates.

Douglas Finkbeiner of the Harvard-Smithsonian Center for Astrophysics, who was not involved in Pospelov's study, isn't yet convinced that dark matter walls exist. But he is glad that physicists are keeping an open mind about alternatives to WIMPs.

"We've looked for WIMP dark matter in so many ways," he says. "At some point you have to ask, are we totally on the wrong track?"

No crime" in paying for assistance during campaigning: SDA

SINGAPORE: The Singapore Democratic Alliance has said there is "no crime" in paying for assistance during the hustings.

The party was referring to its use of supporters, many of them youths, who have been helping in the Punggol East by-election.

The party sent out a statement in response to an online report of supporters being paid to assist in campaigning for its candidate, Desmond Lim.

The statement called Mr Lim "resourceful" for using this means, and clarified that "he has not conducted any corrupt services to induce the voters".

It said that engaging paid assistance in doing ground work is common for any party.

The party added that engaging volunteers allows it to stretch its budget further.

It said it will not hesitate to take legal action if further comments affecting the party's credibility are raised regarding this matter.

Despite setbacks, airlines and passengers still on board the Dreamliner

The Boeing 787 Dreamliner, which has suffered through many years of delays and mechanical issues, is now grounded around the world after a series of incidents including two on-board fires. But experts predict the plane will still be a hit with airlines and passengers when it is once again cleared for takeoff.

Boeing's 787 Dreamliner has suffered through a series of high-profile delays and setbacks, culminating in this week's grounding by the U.S. government, but thanks to its cutting-edge technology, it's almost certain the plane will thrive in spite of the repeated body blows.

The Dreamliner -- the much-heralded, next-generation plane that Boeing designed to offer airlines big fuel efficiencies and access to new intercontinental routes -- had already stumbled through more than three years of delays including an onboard electrical fire before the U.S. Federal Aviation Administration grounded the entire U.S.-based fleet this week in the wake of new on-board fires. Other countries quickly followed suit.

But notwithstanding those problems, the Dreamliner is one blessed airplane, given that while airlines and passengers are certain to be wary of it going forward, few are likely to turn their backs on it for good.

The basic features that got so many people excited about the Dreamliner remain the same, even as the headlines about its fleet-wide grounding blare: Airlines have ordered more than 800 of the new airplane because its first-of-a-kind composite fuselage and new-style engines promise them 20 percent fuel savings, as well as a long-haul range capable of opening up routes never before possible -- or at least, economical -- in a non-stop flight.

At the same time, passengers have been lining up to fly the plane because it's at the vanguard of both in-flight comfort and amenities, and recent excitement over the plane's arrival in new cities like San Jose, Calif. demonstrate just how enthusiastic some are to get on board.

A fire tied to lithium-ion batteries aboard an All Nippon Airways 787 earlier this week, coupled with a similar fire on a Japan Airlines 787 earlier this month, forced the FAA to take action. On January 16, the agency issued an airworthiness directive grounding the entire U.S.-based fleet of Dreamliners -- six United Airlines planes -- until the aircraft can be deemed safe. The two fires followed other recent mishaps on a number of Dreamliners including oil and fuel leaks, a cracked windshield, and false warnings from an electrical panel. "Before further flight," the FAA said in a statement, "operators of U.S.-registered, Boeing 787 aircraft must demonstrate to the Federal Aviation Administration (FAA) that the batteries are safe."

But while Boeing is certainly reeling from the latest setbacks to the $32 billion Dreamliner program, the aviation giant should be able to put these latest episodes behind it and resume delivering the planes before too long, several experts told CNET.

"They'll work this out," said Bob Mann, president of RW Mann, an aviation industry analysis firm. "It's a black eye. It's not a knock-out blow."

To Mann, the likelihood of the Dreamliner program's future success boils down to the fact that the plane features "so much breakthrough innovation" as well as the reality that carriers around the world have made tremendous financial investments in the 787, not to mention that many have based their future business plans on being able to fly the kinds of routes that the plane makes possible for the first time. Plus, having planned for those new routes and fuel costs, they have nowhere to turn: Boeing's chief competitor, Airbus, doesn't have a plane in the works that can match the Dreamliner on these key features.

Though composite materials have been used in some planes for awhile, the Dreamliner is the first to feature a fully-composite fuselage. That makes the plane lighter, making it more fuel efficient, but it also helps make the passenger experience better, according to Mann.

That's because the composite fuselage is stronger than that on other planes, allowing the cabin to be more pressurized. The upshot, explained Mann, is that Dreamliner flights are pressurized to mimic being at an altitude of about 6,000 feet, a much more comfortable environment than on other planes, which are usually pressurized to about a 9,000- or 10,000-foot altitude. And the plane is also designed to have a much more comfortable level of relative humidity, Mann said, because the composite fuselage doesn't need to be kept entirely dry to avoid corrosion.

At the same time, the Dreamliner's fuel efficiency is also driven by the Dreamliner's "no bleed" engines. Boeing claims that "all of the high-speed air produced by the engines goes to thrust [while] pneumatic systems that divert high-speed air from the engines rob conventional airplanes of some thrust and increase the engine's fuel consumption."

For now, no one knows exactly what the root cause of the recent fires is, beyond being tied to the lithium-ion batteries used on the plane. Japanese officials have argued that the battery was operating above its designed voltage limits, according to CBSNews.com.

The 787 relies more than any other modern airliner on electrical signals to help power nearly everything the plane does. It's also the first Boeing plane to use rechargeable lithium-ion batteries for its main electrical system. Such batteries are prone to overheating and have additional safeguards installed that are meant to control the problem and prevent fires.

GS Yuasa Corp., the maker of the lithium-ion batteries used in the 787s, said Thursday it was helping with the investigation but that the cause of the problem was unclear. It said the problem could be the battery, the power source or the electronics system.

And, of course, lithium-ion batteries have been blamed in fires in other products, like Chevrolet's Volt.

The prospect that the Dreamliner's battery system is fundamentally flawed, is, of course, a major concern for Boeing. But no one has yet definitely pinned the problems on the batteries. And to Chris Sloan, an aviation writer and enthusiast who runs Airchive.com, there's nothing particularly unique about the Dreamliner getting off to such a rocky beginning.

Many planes, Sloan argued, have had rough beginnings. Among them are the Lockheed Electra, which had three crashes in its first year; the McDonnell Douglas DC-10, which had a wide range of problems and was grounded following a massive crash in 1979; and the De Havilland Comet, which suffered through a series of stress fractures and crashes. In each case, Sloan said, airlines and passengers returned when the planes were once again cleared for flight. One significant difference between those planes and the Dreamliner is that no 787 has crashed, and no one has died aboard the plane.

Ultimately, said Imperial Capital aviation analyst Ken Herbert, Boeing is likely to be able to count on airlines and passengers continuing to support the Dreamliner because of all the plane's advantages, and particularly because so many airlines have invested so much in the aircraft. "I haven't heard any long term wavering on their desire to take delivery of the plane," Herbert said. "Airlines have planned on this [for years], and for them to change right now, if they're expecting one, it's not an easy switch to make."

To be sure, Boeing has a huge deal riding on the outcome of the investigations being done by the FAA and the U.S. National Transportation Safety Board. If the final determination is that the batteries are incompatible with the plane for one reason or another, it could be a major setback costing Boeing months and significant amounts of money. But short of that worst-case scenario, once the federal agencies sign off on the plane's airworthiness, Herbert has little doubt that the Dreamliner will once again be a favorite of the world's airlines and many aviation enthusiasts.

"I'm not expecting any public pushback or concern about flying on these planes," Herbert said. "Boeing has a lot at stake on her now, and the next few weeks are pretty important from a timing standpoint, and a public perception standpoint, and safety and reliability standpoint. They've got to be really careful that they don't do anything else to jeopardize (the public's) interest in getting on one of these things."

But will passengers come back? Herbert thinks so. "Generally, people still regard the industry as very safe, and they've got a lot of confidence in, [which is] rightfully well-deserved, the improvements Boeing and Airbus have made in their aircraft. Unless there's something else, people will move on quickly."

Attack at Algeria Gas Plant Heralds New Risks for Energy Development

The siege by Islamic militants at a remote Sahara desert natural gas plant in Algeria this week signaled heightened dangers in the region for international oil companies, at a time when they have been expanding operations in Africa as one of the world's last energy frontiers. (See related story: "Pictures: Four New Offshore Drilling Frontiers.")

As BP, Norway's Statoil, Italy's Eni, and other companies evacuated personnel from Algeria, it was not immediately clear how widely the peril would spread in the wake of the hostage-taking at the sprawling In Amenas gas complex near the Libyan border.

Map by National Geographic

Algeria, the fourth-largest crude oil producer on the continent and a major exporter of natural gas and refined fuels, may not have been viewed as the most hospitable climate for foreign energy companies, but that was due to unfavorable financial terms, bureaucracy, and corruption. The energy facilities themselves appeared to be safe, with multiple layers of security provided both by the companies and by government forces, several experts said. (See related photos: "Oil States: Are They Stable? Why It Matters.")

"It is particularly striking not only because it hasn't happened before, but because it happened in Algeria, one of the stronger states in the region," says Hanan Amin-Salem, a senior manager at the industry consulting firm PFC Energy, who specializes in country risk. She noted that in the long civil war that gripped the country throughout the 1990s, there had never been an attack on Algeria's energy complex. But now, hazard has spread from weak surrounding states, as the assault on In Amenas was carried out in an apparent retaliation for a move by French forces against the Islamists who had taken over Timbuktu and other towns in neighboring Mali. (See related story: "Timbuktu Falls.")

"What you're really seeing is an intensification of the fundamental problem of weak states, and empowerment of heavily armed groups that are really well motivated and want to pursue a set of aims," said Amin-Salem. In PFC Energy's view, she says, risk has increased in Mauritania, Chad, and Niger—indeed, throughout Sahel, the belt that bisects North Africa, separating the Sahara in the north from the tropical forests further south.

On Thursday, the London-based corporate consulting firm Exclusive Analysis, which was recently acquired by the global consultancy IHS, sent an alert to clients warning that oil and gas facilities near the Libyan and Mauritanian borders and in Mauritania's Hodh Ech Chargui province were at "high risk" of attack by jihadis.

"A Hot Place to Drill"

The attack at In Amenas comes at a time of unprecedented growth for the oil industry in Africa. (See related gallery: "Pictures: The Year's Most Overlooked Energy Stories.") Forecasters expect that oil output throughout Africa will double by 2025, says Amy Myers Jaffe, executive director of the energy and sustainability program at the University of California, Davis, who has counted 20 rounds of bidding for new exploration at sites in Africa's six largest oil-producing states.

Oil and natural gas are a large part of the Algerian economy, accounting for 60 percent of government budget revenues, more than a third of GDP and more than 97 percent of its export earnings. But the nation's resources are seen as largely undeveloped, and Algeria has tried to attract new investment. Over the past year, the government has sought to reform the law to boost foreign companies' interests in their investments, although those efforts have foundered.

Technology has been one of the factors driving the opening up of Africa to deeper energy exploration. Offshore and deepwater drilling success in the Gulf of Mexico and Brazil led to prospecting now under way offshore in Ghana, Mozambique, and elsewhere. (See related story: "New Oil—And a Huge Challenge—for Ghana.") Jaffe says the Houston-based company Anadarko Petroleum has sought to transfer its success in "subsalt seismic" exploration technology, surveying reserves hidden beneath the hard salt layer at the bottom of the sea, to the equally challenging seismic exploration beneath the sands of the Sahara in Algeria, where it now has three oil and gas operations.

Africa also is seen as one of the few remaining oil-rich regions of the world where foreign oil companies can obtain production-sharing agreements with governments, contracts that allow them a share of the revenue from the barrels they produce, instead of more limited service contracts for work performed.

"You now have the technology to tap the resources more effectively, and the fiscal terms are going to be more attractive than elsewhere—you put these things together and it's been a hot place to drill," says Jaffe, who doesn't see the energy industry's interest in Africa waning, despite the increased terrorism risk. "What I think will happen in some of these countries is that the companies are going to reveal new securities systems and procedures they have to keep workers safe," she says. "I don't think they will abandon these countries."

Te'o Denies Involvement in Girlfriend Hoax

Notre Dame star linebacker Manti Te'o told ESPN that he "never, not ever" was involved in creating the hoax that had him touting what turned out to be a fictional girlfriend, "Lennay Kekua."

"When they hear the facts, they'll know," Te'o told ESPN's Jeremy Schaap in his first interview since the story broke. "They'll know that there is no way that I could be a part of this."

"I wasn't faking it," he said during a 2 1/2-hour interview, according to ESPN.com.

Te'o said he only learned for sure this week that he had been duped. On Wednesday, he received a Twitter message, allegedly from a man named Ronaiah Tuiasosopo, apologizing for the hoax, Te'o told Schaap.

The sports website Deadspin, which first revealed the hoax this week, has reported that Tuiasosopo, a 22-year-old of Samoan descent who lives in Antelope Valley, Calif., asked a woman he knew for her photo and that photo became the face of Kekua's Twitter account.

Te'o told Schaap that Tuiasosopo was represented to him as Kekua's cousin.

"I hope he learns," Te'o said of Tuiasosopo, according to coverage of the interview on ESPN.com. "I hope he understands what he's done. I don't wish an ill thing to somebody. I just hope he learns. I think embarrassment is big enough."

Tale of Notre Dame Football Star's Girlfriend and Her Death an Alleged Hoax Watch Video

Te'o admitted to a few mistakes in his own conduct, including telling his father he met Kekua in Hawaii even though his attempt to meet her actually failed. Later retellings of that tale led to inconsistencies in media reports, Te'o said, adding that he never actually met Kekua in person.

Te'o added that he feared people would think it was crazy for him to be involved with someone that he never met, so, "I kind of tailored my stories to have people think that, yeah, he met her before she passed away."

The relationship got started on Facebook during his freshman year, Te'o said.

"My relationship with Lennay wasn't a four-year relationship," Te'o said, according to ESPN.com. "There were blocks and times and periods in which we would talk and then it would end."

He showed Schaap Facebook correspondence indicating that other people knew of Kekua -- though Te'o now believes they, too, were tricked.

The relationship became more intense, Te'o said, after he received a call that Kekua was in a coma following a car accident involving a drunk driver on April 28.

Soon, Te'o and Kekua became inseparable over the phone, he said, continuing their phone conversations through her recovery from the accident, and then during her alleged battle against leukemia.

Even so, Te'o never tried to visit Kekua at her hospital in California.

"It never really crossed my mind," he said, according to ESPN.com. "I don't know. I was in school."

But the communication between the two was intense. They even had ritual where they discussed scripture every day, Te'o said. His parents also participated via text message, and Te'o showed Schaap some of the texts.

On Sept. 12, a phone caller claiming to be Kekua's relative told Te'o that Kekua had died of leukemia, Te'o said. However, on Dec. 6, Te'o said he got a call allegedly from Kekua saying she was alive. He said he was utterly confused and did not know what to believe.

ESPN's 2 1/2-hour interview was conducted in Bradenton, Fla., with Te'o's lawyer present but without video cameras. Schaap said Te'o was composed, comfortable and in command, and that he said he didn't want to go on camera to keep the setting intimate and avoid a big production.

According to ABC News interviews and published reports, Te'o received phone calls, text messages and letters before every football game from his "girlfriend." He was in contact with her family, including a twin brother, a second brother, sister and parents. He called often to check in with them, just as he did with his own family. And "Kekua" kept in contact with Te'o's friends and family, and teammates spoke to her on the phone.

Zoologger: The first solar-powered vertebrate

Zoologger is our weekly column highlighting extraordinary animals – and occasionally other organisms – from around the world

Species: Ambystoma maculatum
Habitat: throughout the eastern USA and parts of southern Canada, leaving other salamanders green with envy

When you think about it, animals are weird. They ignore the abundant source of energy above their heads – the sun – and choose instead to invest vast amounts of energy in cumbersome equipment for eating and digesting food. Why don't they do what plants do, and get their energy straight from sunlight?

The short answer is that many do. Corals are animals buthave algae living in them that use sunlight to make sugar. Many other animals, from sponges to sea slugs, pull the same trick. One species of hornet can convert sunlight into electricity. There are also suggestions that aphids can harness sunlight, although most biologists are unconvinced.

But all these creatures are only distantly related to us. No backboned animal has been found that can harness the sun – until now. It has long been suspected, and now there is hard evidence: the spotted salamander is solar-powered.

Plants make food using photosynthesis, absorbing light to power a chemical reaction that converts carbon dioxide and water into glucose and releases oxygen. Corals profit from this reaction by housing photosynthetic algae inside their shells.

Long-term partners

Spotted salamanders, too, are in a long-term relationship with photosynthetic algae. In 1888, biologist Henry Orr reported that their eggs often contain single-celled green algae called Oophila amblystomatis. The salamanders lay the eggs in pools of water, and the algae colonise them within hours.

By the 1940s, biologists strongly suspected it was a symbiotic relationship, beneficial to both the salamander embryos and the algae. The embryos release waste material, which the algae feed on. In turn the algae photosynthesise and release oxygen, which the embryos take in. Embryos that have more algae are more likely to survive and develop faster than embryos with few or none.

Then in 2011 the story gained an additional twist. A close examination of the eggs revealed that some of the algae were living within the embryos themselves, and in some cases were actually inside embryonic cells. That suggested the embryos weren't just taking oxygen from the algae: they might be taking glucose too. In other words, the algae were acting as internal power stations, generating fuel for the salamanders.

To find out if that was happening, Erin Graham of Temple University in Philadelphia, Pennsylvania and colleagues incubated salamander eggs in water containing radioactive carbon-14. Algae take up the isotope in the form of carbon dioxide, producing radioactive glucose.

Graham found that the embryos became mildly radioactive – unless kept in the dark. That showed that the embryos could only take in the carbon-14 via photosynthesis in the algae.

Big help

The algae do not seem to be essential to the embryos, but they are very helpful: embryos deprived of algae struggle. "Their survival rate is much lower and their growth is slowed," says Graham.

It's less clear how well the algae get on without the embryos. In the lab, they transform into dormant cysts. The salamander eggs are only around in spring, suggesting that in the wild, the algae spend the rest of the year as cysts. The ponds they live in dry up in summer, so the algae may sit out the rest of the year in the sediment.

Now that one vertebrate has been shown to use photosynthesis, Graham says there could well be others. "Anything that lays eggs in water would be a good candidate," she says, as algae would have easy access to the eggs. So other amphibians, and fish, could be doing it. It's much less likely that a mammal or bird could photosynthesise, as their developing young are sealed off from the outside world.

Authorities checking on property agents who evade stamp duty

SINGAPORE: Channel NewsAsia understands authorities are conducting spot checks on at least seven property developers to find out if they have backdated their documents.

It has been about a week since the latest round of property cooling measures kicked in.

Among the changes is an increase in Additional Buyer's Stamp Duty of five to seven percentage points across the board.

In a bid to help buyers avoid paying the additional stamp duty, industry insiders said some agents have resorted to backdating the date of the Option-to-Purchase for sale and purchase of residential properties.

Avoiding stamp duty is as good as tax evasion, which is an offence.

Industry insiders said authorities have stepped up efforts to conduct spot checks on possible offenders.

So far, industry insiders said one property agent has been caught backdating.

Authorities have also issued circulars to remind developers and agents to comply with the new cooling measures.

Industry players said that they had previously heard of agents trying to backdate options two to three days after cooling measures were introduced.

But as the measures introduced this round are more drastic, they said there are more agents taking the risk.

In some cases, the buyers may be considering whether to buy a property, and the cooling measures could have been introduced before they could decide.

Industry insiders say that is when they may request their agent to backdate their options.

Chris Koh, director of Chris International said: "If you backdate the document, it will probably be on a gentleman agreement, whereby all parties agree to it. But then who knows as you move down the line, one may play the other out, or one may just say 'I choose not to buy or sell anymore, and what we did previously was not the right thing to do'. And therefore they use that as a means to get out of the contract."

Any person guilty of such an offence shall be liable on conviction to a fine of up to S$10,000 or imprisonment of up to three years or to both.

Estate agents or salespersons found involved may face disciplinary action by the Council for Estate Agencies, which could include a financial penalty of up to $75,000 and a suspension or revocation of their licence or registration.

iPad Mini cellular model debuts in China with two-week delay

The iPad Mini.

(Credit:
Apple)

The cellular edition of the iPad Mini debuted in China today, but buyers will have to wait two weeks before it ships.

That delay also applies to the Wi-Fi only version. A check of the Apple Store in China finds that all capacities of both the Wi-Fi and Wi-Fi + Cellular models are stuck with a two-week ship time.

iPad Mini buyers in the U.K., Japan, and other countries face the same delay, though the wait time in the U.S. is only one week.

Apple has been battling to meet global demand for its diminutive
tablet, which has outshined that of its larger 4th-generation cousin. The newest 9.7-inch tablet is in stock at most online Apple stores around the world. In China, the Wi-Fi version is immediately available, while the Wi-Fi + Cellular version offers a wait time of just a few days.

The Wi-Fi Mini and 4th-gen iPad both debuted in Hong Kong on November 2 and in China on December 7. Since then, the smaller tablet has created a feeding frenzy among Chinese buyers. Checks of retailers in China and Hong Kong last month by Topeka Capital Markets analyst Brian White revealed "an insatiable appetite" for the Mini, causing a supply shortage.

iPad sales for last quarter may actually ring in lower than expected due to supply contraints, according to J.P. Morgan analyst Mark Moskowitz.

In an investors note out yesterday, the analyst forecast unit sales of 18.4 million for the Mini and the iPad 4 combined, down from his previous estimate of 20.1 million. The analyst does view the downturn as a temporary glitch, noting that iPad supply started to improve in early December.

However, financial advisory firm Macquarie Research believes the problem will extend to the current quarter, according to Reuters. Macquarie's crystal ball sees shipments of the larger iPad dropping almost 40 percent in the present quarter to around 8 million. That's down from its prior forecast of 13 million, though the firm believes total tablet shipments will show a smaller decline due to heavy sales of the iPad Mini.

Opinion: Lance One of Many Tour de France Cheaters

Editor's note: England-based writer and photographer Roff Smith rides around 10,000 miles a year through the lanes of Sussex and Kent and writes a cycling blog at: www.my-bicycle-and-I.co.uk

And so, the television correspondent said to the former Tour de France champion, a man who had been lionised for years, feted as the greatest cyclist of his day, did you ever use drugs in the course of your career?

"Yes," came the reply. "Whenever it was necessary."

"And how often was that?" came the follow-up question.

"Almost all the time!"

This is not a leak of a transcript from Oprah Winfrey's much anticipated tell-all with disgraced cyclist Lance Armstrong, but instead was lifted from a decades-old interview with Fausto Coppi, the great Italian road cycling champion of the 1940s and 1950s.

To this day, though, Coppi is lauded as one of the gods of cycling, an icon of a distant and mythical golden age in the sport.

So is five-time Tour winner Jacques Anquetil (1957, 1961-64) who famously remarked that it was impossible "to ride the Tour on mineral water."

"You would have to be an imbecile or a crook to imagine that a professional cyclist who races for 235 days a year can hold the pace without stimulants," Anquetil said.

And then there's British cycling champion Tommy Simpson, who died of heart failure while trying to race up Mont Ventoux during the 1967 Tour de France, a victim of heat, stress, and a heady cocktail of amphetamines.

All are heroes today. If their performance-enhancing peccadillos are not forgotten, they have at least been glossed over in the popular imagination.

As the latest chapter of the sorry Lance Armstrong saga unfolds, it is worth looking at the history of cheating in the Tour de France to get a sense of perspective. This is not an attempt at rationalisation or justification for what Lance did. Far from it.

But the simple, unpalatable fact is that cheating, drugs, and dirty tricks have been part and parcel of the Tour de France nearly from its inception in 1903.

Cheating was so rife in the 1904 event that Henri Desgrange, the founder and organiser of the Tour, declared he would never run the race again. Not only was the overall winner, Maurice Garin, disqualified for taking the train over significant stretches of the course, but so were next three cyclists who placed, along with the winner of every single stage of the course.

Of the 27 cyclists who actually finished the 1904 race, 12 were disqualified and given bans ranging from one year to life. The race's eventual official winner, 19-year-old Henri Cornet, was not determined until four months after the event.

And so it went. Desgrange relented on his threat to scrub the Tour de France and the great race survived and prospered-as did the antics. Trains were hopped, taxis taken, nails scattered along the roads, partisan supporters enlisted to beat up rivals on late-night lonely stretches of the course, signposts tampered with, bicycles sabotaged, itching powder sprinkled in competitors' jerseys and shorts, food doctored, and inkwells smashed so riders yet to arrive couldn't sign the control documents to prove they'd taken the correct route.

And then of course there were the stimulants-brandy, strychnine, ether, whatever-anything to get a rider through the nightmarishly tough days and nights of racing along stages that were often over 200 miles long. In a way the race was tailor-made to encourage this sort of thing. Desgrange once famously said that his idea of a perfect Tour de France would be one that was so tough that only one rider finished.

Add to this the big prizes at a time when money was hard to come by, a Tour largely comprising young riders from impoverished backgrounds for whom bicycle racing was their one big chance to get ahead, and the passionate following cycling enjoyed, and you had the perfect recipe for a desperate, high stakes, win-at-all-costs mentality, especially given the generally tolerant views on alcohol and drugs in those days.

After World War II came the amphetamines. Devised to keep soldiers awake and aggressive through long hours of battle they were equally handy for bicycle racers competing in the world's longest and toughest race.

So what makes the Lance Armstrong story any different, his road to redemption any rougher? For one thing, none of the aforementioned riders were ever the point man for what the U.S. Anti-Doping Agency has described in a thousand-page report as the most sophisticated, cynical, and far-reaching doping program the world of sport has ever seen-one whose secrecy and efficiency was maintained by ruthlessness, bullying, fear, and intimidation.

Somewhere along the line, the casualness of cheating in the past evolved into an almost Frankenstein sort of science in which cyclists, aided by creepy doctors and trainers, were receiving blood transfusions in hotel rooms and tinkering around with their bodies at the molecular level many months before they ever lined up for a race.

To be sure, Armstrong didn't invent all of this, any more than he invented original sin-nor was he acting alone. But with his success, money, intelligence, influence, and cohort of thousand-dollar-an-hour lawyers-and the way he used all this to prop up the Lance brand and the Lance machine at any cost-he became the poster boy and lightning rod for all that went wrong with cycling, his high profile eclipsing even the heads of the Union Cycliste Internationale, the global cycling union, who richly deserve their share of the blame.

It is not his PED popping that is the hard-to-forgive part of the Lance story. Armstrong cheated better than his peers, that's all.

What I find troubling is the bullying and calculated destruction of anyone who got in his way, raised a question, or cast a doubt. By all accounts Armstrong was absolutely vicious, vindictive as hell. Former U.S. Postal team masseuse Emma O'Reilly found herself being described publicly as a "prostitute" and an "alcoholic," and had her life put through a legal grinder when she spoke out about Armstrong's use of PEDs.

Journalists were sued, intimidated, and blacklisted from events, press conferences, and interviews if they so much as questioned the Lance miracle or well-greased machine that kept winning Le Tour.

Armstrong left a lot of wreckage behind him.

If he is genuinely sorry, if he truly repents for his past "indiscretions," one would think his first act would be to try to find some way of not only seeking forgiveness from those whom he brutally put down, but to do something meaningful to repair the damage he did to their lives and livelihoods.

Armstrong Admits to Doping, 'One Big Lie'

Lance Armstrong, formerly cycling's most decorated champion and considered one of America's greatest athletes, confessed to cheating for at least a decade, admitting on Thursday that he owed all seven of his Tour de France titles and the millions of dollars in endorsements that followed to his use of illicit performance-enhancing drugs.

After years of denying that he had taken banned drugs and received oxygen-boosting blood transfusions, and attacking his teammates and competitors who attempted to expose him, Armstrong came clean with Oprah Winfrey in an exclusive interview, admitting to using banned substances for years.

"I view this situation as one big lie that I repeated a lot of times," he said. "I know the truth. The truth isn't what was out there. The truth isn't what I said.

"I'm a flawed character, as I well know," Armstrong added. "All the fault and all the blame here falls on me."

In October, the U.S. Anti-Doping Agency issued a report in which 11 former Armstrong teammates exposed the system with which they and Armstrong received drugs with the knowledge of their coaches and help of team physicians.

The U.S. Postal Service Cycling Team "ran the most sophisticated, professionalized and successful doping program that sport has ever seen," USADA said in its report.

As a result of USADA's findings, Armstrong was stripped of his Tour de France titles. Soon, longtime sponsors including Nike began to abandon him, too.

Armstrong said he was driven to cheat by a "ruthless desire to win."

He told Winfrey that his competition "cocktail" consisted of EPO, blood transfusions and testosterone, and that he had previously used cortisone. He would not, however, give Winfrey the details of when, where and with whom he doped during seven winning Tours de France between 1999 and 2005.

He said he stopped doping following his 2005 Tour de France victory and did not use banned substances when he placed third in 2009 and entered the tour again in 2010.

"It was a mythic perfect story and it wasn't true," Armstrong said of his fairytale story of overcoming testicular cancer to become the most celebrated cyclist in history.

Armstrong would not name other members of his team who doped, but admitted that as the team's captain he set an example. He admitted he was "a bully" but said there "there was a never a directive" from him that his teammates had to use banned substances.

"At the time it did not feel wrong?" Winfrey asked.

"No," Armstrong said. "Scary."

"Did you feel bad about it?" she asked again.

"No," he said.

Armstrong said he thought taking the drugs was similar to filling his tires with air and bottle with water. He never thought of his actions as cheating, but "leveling the playing field" in a sport rife with doping.

Cycling: IOC asks Armstrong to return Olympic medal

LAUSANNE: The International Olympic Committee (IOC) on Thursday asked disgraced American cyclist Lance Armstrong to return the Olympic bronze medal from the time-trial event at the 2000 Games in Sydney.

The IOC had written to Armstrong late Wednesday to ask him hand back the medal, IOC spokesman Mark Adams told AFP.

The IOC had to wait for world cycling's governing body to sanction Armstrong, which it did on December 6, and the following three weeks in which the Texan had recourse to appeal at the Court of Arbitration for Sport (CAS).

The US Olympic Committee, to which Armstrong must theoretically return the medal, has also been informed, Adams added.

Armstrong was stripped of his seven Tour de France titles and banned from the sport for life in October after the US Anti-Doping Agency (USADA) produced evidence of widespread doping by him and his former team-mates.

The time-trial in the 2000 Games was won by Armstrong's ex-US Postal Service teammate Viasheslav Ekimov of Russia, now general manager of the Katusha team whose ambivalent stance on doping cost them a place in the elite ProTeam list for this season.

The silver medal went to one of Armstrong's great rivals, Jan Ullrich of Germany, who was caught up in the Operation Puerto doping probe and eventually served a two-year ban for doping.

Abraham Olano of Spain came home in fourth and may be set to inherit the bronze vacated by Armstrong.

Other notable results in the race held in Sydney were by American Tyler Hamilton, a former teammate of Armstrong at US Postal who finished tenth and went on to win gold at the 2004 Athens Games before testing positive for doping.

British rider David Millar finished 16th and is still currently on the circuit after serving his own two-year ban from 2004.

The International Cycling Union (UCI) late last year effectively erased Armstrong from the cycling history books when it decided not to appeal sanctions imposed on the Texan rider by the USADA.

In his first interview since Armstrong was shorn of his Tour titles, recorded Monday with Oprah Winfrey and due to be broadcast on Thursday and Friday, the chat show host confirmed that the Texan admitted using performance-enhancing drugs.

iPad sales may be lower than expected, says analyst

Apple's iPad.

(Credit:
Apple)

The iPad may have missed out on a healthy chunk of sales last quarter due to limited supply, says J.P. Morgan analyst Mark Moskowitz.

In an investors note out today, Moskowitz said he believes iPad unit sales will be lighter than expected for the final quarter of 2012. He's now predicting sales of 18.4 million, down from his prior forecast of 20.1 million.

"Our research indicates that near-term supply constraints impacted iPad sell-in activity during the seasonally-stronger holiday season," the analyst said. "Supply did not improve until early December. In our view, it was a supply, not demand issue."

Moskowitz sees the iPad shortfall as a short-term "blip." But he believes Apple's explanation of the sales decline will be important, especially as the iPad gears up to take on a bigger role over the next few years.

"We think that, barring entry of another new category, the iPad likely will need to shoulder more of the incremental revenue growth as the iPhone's incremental growth starts to taper off in coming years," the analyst said.

Apple has been hurt lately by reports of a cut in iPhone 5 component orders. But like a few other analysts, Moskowitz sees this as "bear mongering" and believes Apple will likely grow along with the overall smartphone market.

Looking at unit sales, J.P Morgan sees the global smartphone market growing 30.5 percent this year. Over the same time, the iPhone is forecast to grow 28.6 percent.

Apple should be able to eke out more profits from the iPhone, particularly as carriers in Europe ramp up their LTE networks over the next 12 to 18 months.

The analyst has upped his forecast for the iPhone's gross margins in the belief that the recent order cuts may be a sign of manufacturing improvements. If margins on the
iPhone 5 can return to 40 percent, Moskowitz believes the "bear mongering" is likely to ease up. He expects fourth-quarter iPhone sales to reach 47.9 million, with the iPhone 5 accounting for 25 million of those.

Notre Dame: Football Star Was 'Catfished' in Hoax

Notre Dame's athletic director and the star of its near-championship football team said the widely-reported death of the star's girlfriend from leukemia during the 2012 football season was apparently a hoax, and the player said he was duped by it as well.

Manti Te'o, who led the Fighting Irish to the BCS championship game this year and finished second for the Heisman Trophy, said in a statement today that he fell in love with a girl online last year who turned out not to be real.

The university's athletic director, Jack Swarbrick, said it has been investigating the "cruel hoax" since Te'o approached officials in late December to say he believed he had been tricked.

Private investigators hired by the university subsequently monitored online chatter by the alleged perpetrators, Swarbrick said, adding that he was shocked by the "casual cruelty" it revealed.

"They enjoyed the joke," Swarbrick said, comparing the ruse to the popular film "Catfish," in which filmmakers revealed a person at the other end of an online relationship was not who they said they were.

"While we still don't know all of the dimensions of this ... there are certain things that I feel confident we do know," Swarbrick said. "The first is that this was a very elaborate, very sophisticated hoax, perpetrated for reasons we don't understand."

Te'o said during the season that his girlfriend, Lennay Kekua, died of leukemia in September on the same day Te'o's grandmother died, triggering an outpouring of support for Te'o at Notre Dame and in the media.

"While my grandma passed away and you take, you know, the love of my life [Kekua]. The last thing she said to me was, 'I love you,'" Te'o said at the time, noting that he had talked to Kekua on the phone and by text message until her death.

Now, responding to a story first reported by the sports website Deadspin, Te'o has acknowledged that Kekua never existed. The website reported today that there were no records of a woman named Lennay Kekua anywhere.

Te'o denied that he was in on the hoax.

"This is incredibly embarrassing to talk about, but over an extended period of time, I developed an emotional relationship with a woman I met online," Te'o said in a statement released this afternoon. "We maintained what I thought to be an authentic relationship by communicating frequently online and on the phone, and I grew to care deeply about her."

Swarbrick said he expected Te'o to give his version of events at a public event soon, perhaps Thursday, and that he believed Te'o's representatives were planning to disclose the truth next week until today's story broke.

Deadspin reported that the image attached to Kekua's social media profiles, through which the pair interacted, was of another woman who has said she did not even know Te'o or know that her picture was being used. The website reported that it traced the profiles to a California man who is an acquaintance of Te'o and of the woman whose photo was stolen.

"To realize that I was the victim of what was apparently someone's sick joke and constant lies was, and is, painful and humiliating," Te'o said.

NASA rover ready to drill into Martian rock

Victoria Jaggard, physical sciences news editor

(Image: NASA/JPL-Caltech/MSSS)

NASA's Curiosity rover is about to tap the rocky veins of Mars, which might yield clues to the Red Planet's watery past.

Exploring a region not far from where it landed on 6 August, the Curiosity rover has found rocks shot through with veins of light-coloured minerals. Chemical analysis from one of the rover's remote-sensing cameras shows that the veins are hydrated calcium sulphates, possibly gypsum. They probably formed when water flowed through fractures in the bedrock and left dissolved material behind behind.

The find takes NASA's mantra "follow the water" to a whole new level.

"The exciting thing about precipitated minerals is that we know something dissolved rock somewhere else on the planet and ions got transported along by a fluid," said project scientist John Grotzinger during a teleconference yesterday. Studying the mineral-laced rocks can give clues to where the water came from and to environmental conditions when the veins formed.

The team will use the rover's drill for the first time on a veined outcrop named John Klein, an homage to a former project worker who died in 2011. The drill can bite about 5 centimetres into Martian rock, collect pulverised samples and deliver material to other onboard instruments for analysis.

"What we are hoping to do is get a sense of the mineralogy - how many aqueous mineral phases are present, the isotope ratios, and even a chance to look for organics," Grotzinger said.

Although initially thought too soft to preserve fossils, previous work showed that gypsum on Earth can hold traces of ancient carbon-based life.

Elsewhere at the site - a shallow depression dubbed Yellowknife Bay - the rover has spotted rocks studded with rounded features called spherules, which also tell of fluids at work.

"We are feeling confident these are sedimentary concretions [rocks formed as sediments washed from afar become cemented together]," Grotzinger said. "Put that together with the veins, and basically these rocks were saturated with water."

Another outcrop at the site shows a texture called cross-bedding, which resembles stacked layers of rock. These features on Earth are associated with water pushing small dunes of sediments along a stream bed. "There's a real trend that's emerging here on our tour," Grotzinger said.

The team won't be ready to drill for a few weeks yet, as they continue to take samples with other instruments and then drive the rover to the John Klein outcrop.

"It takes a fairly extended period of time because drilling is the most significant engineering thing we've done since landing," said rover project manager Richard Cook. Team members have also been examining and recording the great diversity of rock types at Yellowknife Bay, some of which may also become targets for drilling.

"It's safe to say scientists have been led into the candy store," Cook said. "I'm really excited about the next few weeks."

Japan mulling military equipment near disputed isles

TOKYO: Japan may station military equipment on islands near an archipelago at the centre of a dispute with China, officials said Wednesday, after a number of airborne near-confrontations.

The defence ministry will ask for money in the next fiscal year to study the idea of putting mobile radars and communication systems on islands near the Japan-controlled Senkakus, which Beijing calls the Diaoyus, a defence spokesman said.

"The study is part of our plan to operate in southwestern islands with flexibility," the spokesman said.

The comment came after reports said Japan is considering permanently stationing F-15 fighter jets on Shimoji, a small island near the Senkakus.

Defence Minister Itsunori Onodera denied that and said Tuesday: "We are studying various options as to how to build a sound security system in our southwestern waters."

The maritime dispute, which has simmered for years, heated up last year when the Japanese government nationalised some of the islands, triggering anger and demonstrations in China.

Observers said the protests had some backing from communist authorities in Beijing, who use nationalism to bolster their claims to legitimacy.

Tokyo's defence ministry has said F-15s were sent airborne to head off Chinese state-owned -- but not military -- planes four times in December, including one occasion when Japanese airspace was breached.

They were also mobilised in January, it said.

On the occasion when Japan says its airspace was breached, the air force did not detect the Chinese aircraft, which had already moved off by the time fighter jets were scrambled.

Sony exec hints at PlayStation 4 launch in spring

Sony introduced a super slim version of its PlayStation 3 in September.

(Credit:
Sony Computer Entertainment America)

Sony's vice president of home entertainment, Hiroshi Sakamoto, has hinted that the next-generation Playstation 4 console may be announced in the coming months.

In an interview with Chilean Web site Emol, Sakamoto implied that the Playstation 4 may be ready for formal introduction by the time 2013's Electronic Entertainment Expo (E3) appears on the calendar, or perhaps even sooner.

When asked whether a next-generation playstation console will be seen within the new few months, the VP told the publication:

That's still a big secret, but our friends are preparing Sony PlayStation. I can only say that we are focused on the E3 gaming event, scheduled for June. [An] announcement may be [made] in that minute or even earlier in May.

Sakamoto went on to say that there would "probably" be a big announcement at E3, but consumers will have to wait until May at the earliest. Even if the hardware is revealed at E3 -- an event comparable to
CES for gamers -- it is unlikely we will get our hands on the console, reportedly being developed under the project name "Orbis," until later in the year.

Whenever it arrives, Sony's next console will be contending for consumer dollars against the likes of Microsoft's yet-to-be-introduced next-generation XBox.

Rumors surrounding Sony's next console have suggested that the Playstation 4's specifications will include a customized chip based on AMD's A8-3850 with a quad-core 2.9GHz processor and a 1GHz graphics card with 1GB of dedicated memory. Hardly the cutting edge of technology, but as other reports have suggested that the console has been designed for affordability, these kinds of facilities aren't surprising.

Most console manufacturers have generally kept to the tradition of a five-year shelf life for their devices. However, Sony has always gone against the grain, saying that its products have double the lifespan -- and as long they remain commercially viable. Patrick Seybold, senior director of corporate communications for Sony Computer Entertainment, told CNET last year:

We at PlayStation have never subscribed to the concept that a console should last only a half-decade. Both the original PlayStation and PlayStation 2 had life cycles of more than 10 years, and PlayStation 3 will as well. The 10-year life cycle is a commitment we've made with every PlayStation consumer to date, and it's part of our philosophy that we provide hardware that will stand the test of time providing that fun experience you get from day one for the next decade.

Mars Rover Finds Intriguing New Evidence of Water

The first drill sample ever collected on Mars will come from a rockbed shot through with unexpected veins of what appears to be the mineral gypsum.

Delighted members of the Curiosity science team announced Tuesday that the rover was now in a virtual "candy store" of scientific targets—the lowest point of Gale crater, called Yellowknife Bay, is filled with many different materials that could have been created only in the presence of water. (Related: "Mars Has 'Oceans' of Water Inside?")

Project scientist John Grotzinger, of the California Institute of Technology in Pasadena, said during a press conference that the drill area has turned out "to be jackpot unit. Every place we drive exposes fractures and vein fills."

Mission scientists initially decided to visit the depression, a third of a mile from Curiosity's landing site, on a brief detour before heading to the large mountain at the middle of Gale Crater. But because of the richness of their recent finds, Grotzinger said it may be some months before they begin their trek to Mount Sharp.

The drilling, expected to start this month, will dig five holes about two inches (five centimeters) into bedrock the size of a throw rug and then feed the powder created to the rover's two chemistry labs for analysis.

The drill is the most complex device on the rover and is the last instrument to be used. Project Manager Richard Cook, of NASA's Jet Propulsion Laboratory, said that operating it posed the biggest mechanical challenge since Curiosity's high-drama landing. (Watch video of Curiosity's "Seven Minutes of Terror.")

A Watery Past?

That now-desiccated Mars once had a significant amount of surface water is now generally accepted, but every new discovery of when and where water was present is considered highly significant. The presence of surface water in its many possible forms—as a running stream, as a still lake, as ground water soaked into the Martian soil—all add to an increased possibility that the planet was once habitable. (Watch a video about searching for life on Mars.)

And each piece of evidence supporting the presence of water brings the Curiosity mission closer to its formal goal—which is to determine whether Mars was once capable of supporting life.

Curiosity scientists have already concluded that a briskly moving river or stream once flowed near the Gale landing site.

The discovery of the mineral-filled veins within Yellowknife Bay rock fractures adds to the picture because those minerals can be deposited only in watery, underground conditions.

The Curiosity team has also examined Yellowknife Bay for sedimentary rocks with the rover's Mars Hand Lens Imager (MAHLI).  Scientists have found sandstone with grains up to about the size of a peppercorn, including one shaped like a flower bud that appears to gleam. Other nearby rocks are siltstone, with grains finer than powdered sugar. These are quite different from the pebbles and conglomerate rocks found in the landing area, but all these rocks are evidence of a watery past. (Related: "A 2020 Rover Return to Mars?")

One of the primary reasons Curiosity scientists selected Gale crater as a landing site was because satellite images indicated that water-formed minerals were present near the base of Mount Sharp. Grotzinger said that the minerals' presence so close to the landing site, and some five miles from the mountain, is both a surprise and an opportunity.

The current site in Yellowknife Bay is so promising, Grotzinger said, that he would have been "thrilled" to find similar formations at the mission's prime destination at the base of Mount Sharp.  Now the mission can look forward to the surprises to come at the mountain base while already having struck gold.

NRA Ad Calls Obama 'Elitist Hypocrite'

Jan 16, 2013 12:04am

Pablo Martinez Monsivais/AP Photo

As the White House prepares to unveil a sweeping plan aimed at curbing gun violence, the National Rifle Association has launched a preemptive, personal attack on President Obama, calling him an “elitist hypocrite” who, the group claims, is putting American children at risk.

In 35-second video posted online Tuesday night, the NRA criticizes Obama for accepting armed Secret Service protection for his daughters, Sasha and Malia, at their private Washington, D.C., school while questioning the placement of similar security at other schools.

“Are the president’s kids more important than yours? Then why is he skeptical about putting armed security in our schools, when his kids are protected by armed guards at their school?” the narrator says.

“Mr. Obama demands the wealthy pay their fair share of taxes, but he’s just another elitist hypocrite when it comes to a fair share of security,” it continues. “Protection for their kids and gun-free zones for ours.”

The immediate family members of U.S. presidents – generally considered potential targets – have long received Secret Service protection.

The ad appeared on a new website for a NRA advocacy campaign – “NRA Stand and Fight” — that the gun-rights group appears poised to launch in response to Obama’s package of gun control proposals that will be announced today.

It’s unclear whether the video will air on TV or only on the web. The NRA did not respond to ABC News’ request for comment.  The domain for the website is registered to Ackerman McQueen, the NRA’s long-standing public relations firm.

The White House had no comment on the NRA ad.

In the wake of last month’s mass shooting at Sandy Hook Elementary School, the Obama administration has met with a cross-section of advocacy groups on all sides of the gun debate to formulate new policy proposals.

The NRA, which met with Vice President Joe Biden last week, has opposed any new legislative gun restrictions, including expanded background checks and limits on the sale of assault-style weapons, instead calling for armed guards at all American schools.

Obama publicly questioned that approach in an interview with “Meet the Press” earlier this month, saying, “I am skeptical that the only answer is putting more guns in schools. And I think the vast majority of the American people are skeptical that that somehow is going to solve our problem.”

Still, the White House has been considering a call for increased funding for police officers at public schools and the proposal could be part of a broader Obama gun policy package.

Fifty-five percent of Americans in the latest ABC News/Washington Post poll say they support adding armed guards at schools across the country.

“The issue is, are there some sensible steps that we can take to make sure that somebody like the individual in Newtown can’t walk into a school and gun down a bunch of children in a shockingly rapid fashion.  And surely, we can do something about that,” Obama said at a news conference on Monday.

“Responsible gun owners, people who have a gun for protection, for hunting, for sportsmanship, they don’t have anything to worry about,” he said.

ABC News’ Mary Bruce and Jay Shaylor contributed reporting.

Extended smoking ban takes effect

SINGAPORE: The extended smoking ban in public areas kicked in on Tuesday.

The National Environment Agency (NEA) said it will step up spot checks by about 70 per cent after three months, which is some 8,000 additional hours per month.

In a spot check at Toa Payoh MRT station on Tuesday, seven smokers were caught in an hour for smoking where they were not supposed to.

Smokers are now not allowed to light up at the common areas of all residential buildings, covered linkways and walkways, overhead pedestrian bridges, as well as within a five-metre radius of bus shelters.

For the first three months of the new ban, the NEA said it will take on a more advisory approach.

But come April 15, first time offenders will be fined S$200, while repeat offenders could be fined as much as S$1,000.

Eileen Yap, a NEA inspector, said: "We realise that the public in general are not aware of such bans and the awareness level is not so high in the beginning, so in these three months, NEA will be advising smokers and we'll be working with the community in general to create awareness, so that everyone can have cleaner air."

Smokers hope the NEA will exercise some flexibility when it comes to enforcing the ban.

A smoker, who did not reveal his name, said: "We can't be smoking outside when it's raining or pouring. So they have to fine tune the balance. They probably have to list down under what circumstance it's forgivable, or if there is a second chance, or if not they have to find a solution - a sheltered smoking area for example."

Last year, some 4,000 smokers were caught flouting the rules. This is 800 cases, or 17 per cent less than in 2011.

Belgian group to sue 'deaf' Apple over warranty policy

Accusing Apple of a "misleading" and "illegal" AppleCare warranty policies, a Belgian consumer rights group will be taking the tech giant to court.

The Cupertino, Calif., company has come under fire after allegations were made that AppleCare, Apple's warranty system for products including the
iPad and iPhone, does not conform to European law. As a result, Belgian consumer watchdog Test-Aankoop/Test-Achats has filed a complaint against the company (Dutch).

European consumer law states that within the European Union, two years' warranty must be provided for products free of charge. However, for customers elsewhere, AppleCare has to be paid for after the first year -- and questions have been raised over whether Apple's marketing and contractual practices are an attempt to mislead consumers who do not realize this entitlement.

Apple has gotten itself into trouble previously, after business methods were employed which potentially kept European consumers in the dark over the EU's warranty regulations. The firm was fined $1.2 million by an Italian antitrust watchdog in 2011 after the group ruled that Apple had failed to properly inform its customers of their rights, a judgement Apple later appealed and lost.

Test-Aankoop/Test-Achats says within the filing that "major problems" have been found in the information Apple provides to its Belgian customers, and the lucrative "AppleCare Protection Plan" extension of two or three years goes against the legal guarantee that European law is meant to enforce.

This is not the first time the Belgian group have taken Apple to task. In March last year, the consumer watchdog joined forces with 10 European consumer organizations to complain about Apple's practices, but says that the firm remained "deaf to demands," which has rendered the court case necessary.

Test-Aankoop/Test-Achats says it is confident of a positive outcome of the case, which will be brought before the President of the Commercial Court of Brussels.

This story originally appeared at ZDNet's Between the Lines under the headline "Belgium watchdogs: Apple is 'deaf to demands' over consumer rights.

"Fantastic" New Flying Frog Found—Has Flappy Forearms

Scientists have stumbled across a new species of flying frog—on the ground.

While hiking a lowland forest in 2009, not far from Ho Chi Minh City (map), Vietnam, "we came across a huge green frog, sitting on a log," said Jodi Rowley, an amphibian biologist at the Australian Museum in Sydney and lead author of a new study on the frog.

Rowley later discovered that the 3.5-inch-long (9-centimeter-long) creature is a relatively large new type of flying frog, a group known for its ability to "parachute" from tree to tree thanks to special aerodynamic adaptations, such as webbed feet, Rowley said. (Also see "'Vampire Flying Frog' Found; Tadpoles Have Black Fangs.")

Rowley dubbed the new species Helen's flying frog, in honor of her mother, Helen Rowley, "who has steadfastly supported her only child trekking through the forests of Southeast Asia in search of frogs," according to a statement.

The newfound species—there are 80 types of flying frogs—is also "one of the most flying frogs of the flying frogs," Rowley said, "in that it's got huge hands and feet that are webbed all the way to the toepad."

"Females even have flappy skin on their forearms to glide," added Rowley, who has received funding from the National Geographic Committee on Research and Exploration. (National Geographic News is part of the National Geographic Society.) "The females are larger and heavier than males, so the little extra flaps probably don't make much of a difference," she said.

As Rowley wrote on her blog, "At first it may seem strange that such a fantastic and obvious frog could escape discovery until now—less than 100 kilometers [60 miles] from an urban centre with over nine million people."

Yet these tree dwellers can easily escape notice—they spend most of their time in the canopy, she said.

Flying Frog On the Edge

Even so, Helen's flying frog won't be able to hide from development near Ho Chi Minh City, which may encroach on its existing habitats.

So far, only five individuals have been found in two patches of lowland forest hemmed in by rice paddies in southern Vietnam, Rowley said. The animals can probably tolerate a little bit of disturbance as long as they have large trees and temporary pools, she added.

But lowland forests are among the most threatened habitats in the world, mostly because they're so accessible to people, and thus chosen for logging and development. (Get the facts on deforestation.)

"While Helen's flying frog has only just been discovered by biologists," Rowley wrote, "unfortunately this species, like many others, is under great threat from ongoing habitat loss and degradation."

The new flying frog study was published in December 2012 in the Journal of Herpetology.

Armstrong Admits Doping in Tour, Sources Say

Lance Armstrong today admitted to Oprah Winfrey that he used performance enhancing drugs to win the Tour de France, sources told ABC News.

A government source tells ABC News that Armstrong is now talking with authorities about paying back some of the US Postal Service money from sponsoring his team. He is also talking to authorities about confessing and naming names, giving up others involved in illegal doping. This could result in a reduction of his lifetime ban, according to the source, if Armstrong provides substantial and meaningful information.

Armstrong made the admission in what sources describe as an emotional interview with Winfrey to air on "Oprah's Next Chapter" on Jan. 17.

The 90-minute interview at his home in Austin, Texas, was Armstrong's first since officials stripped him of his world cycling titles in response to doping allegations.

Word of Armstrong's admission comes after a Livestrong official said that Armstrong apologized today to the foundation's staff ahead of his interview.

The disgraced cyclist gathered with about 100 Livestrong Foundation staffers at their Austin headquarters for a meeting that included social workers who deal directly with patients as part of the group's mission to support cancer victims.

Armstrong's "sincere and heartfelt apology" generated lots of tears, spokeswoman Katherine McLane said, adding that he "took responsibility" for the trouble he has caused the foundation.

McLane declined to say whether Armstrong's comments included an admission of doping, just that the cyclist wanted the staff to hear from him in person rather than rely on second-hand accounts.

Armstrong then took questions from the staff.

Armstrong's story has never changed. In front of cameras, microphones, fans, sponsors, cancer survivors -- even under oath -- Lance Armstrong hasn't just denied ever using performance enhancing drugs, he has done so in an indignant, even threatening way.

Armstrong, 41, was stripped of his seven Tour de France titles and banned from the sport for life by the U.S. Anti-Doping Agency in October 2012, after allegations that he benefited from years of systematic doping, using banned substances and receiving illicit blood transfusions.

"Lance Armstrong has no place in cycling and he deserves to be forgotten in cycling," Pat McQuaid, the president of the International Cycling Union, said at a news conference in Switzerland announcing the decision. "This is a landmark day for cycling."

The U.S. Anti-Doping Agency issued a 200-page report Oct. 10 after a wide-scale investigation into Armstrong's alleged use of performance-enhancing substances.

Armstrong won the Tour de France from 1999 to 2005.

According to a source, speaking to ABC News, a representative of Armstrong's once offered to make a donation estimated around $250,000 to the agency, as "60 Minutes Sports" on Showtime first reported.

Lance Armstrong's attorney Tim Herman denied it. "No truth to that story," Herman said. "First Lance heard of it was today. He never made any such contribution or suggestion."

Armstrong, who himself recovered from testicular cancer, created the Lance Armstrong Foundation (now known as the LIVESTRONG Foundation) to help people with cancer cope, as well as foster a community for cancer awareness. Armstrong resigned late last year as chairman of the LIVESTRONG Foundation, which raised millions of dollars in the fight against cancer.
