Zebrafish made to grow pre-hands instead of fins

PERHAPS the little fish embryo shown here is dancing a jig because it has just discovered that it has legs instead of fins. Fossils show that limbs evolved from fins, but a new study shows how it may have happened, live in the lab.

Fernando Casares of the Spanish National Research Council and his colleagues injected zebrafish with the hoxd13 gene from a mouse. The protein that the gene codes for controls the development of autopods, a precursor to hands, feet and paws.

Zebrafish naturally carry hoxd13 but produce less of the protein than tetrapods - all four-limbed vertebrates and birds - do. Casares and his colleagues hoped that by injecting extra copies of the gene into the zebrafish embryos, some of their cells would make more of the protein.

One full day later, all of those fish whose cells had taken up the gene began to develop autopods instead of fins. They carried on growing for four days but then died (Cell, DOI: 10.1016/j.devcel.2012.10.015).

"Of course, we haven't been able to grow hands," says Casares. He speculates that hundreds of millions of years ago, the ancestors of tetrapods began expressing more hoxd13 for some reason and that this could have allowed them to evolve autopods.

2,500 needy families to get help with childcare costs

SINGAPORE: Some 2,500 low-income families will benefit from a S$250,000 initiative to help their children.

The five Commmunity Development Councils will help identify eligible families with monthly household incomes of less than S$3,500.

OCBC Bank will also contribute S$100 when a low-income family deposits the first S$50 into their Child Development Account (CDA).

Under the existing Baby Bonus scheme, the government will match the contributions to the CDA dollar for dollar.

The money in the account can then be used at approved institutions for the child's development and healthcare needs.

Acting Minister for Social and Family Development Chan Chun Sing said: "This year, we have also expanded the kinds of things that you can spend the CDA money (on). For example, it will also include early intervention programmes, visits to the doctor, medical insurance and purchase of healthcare-related products. We hope that in this small way, we can help families to defray the cost of bringing up the children, especially for the needy families."

Under the initiative, parents can also attend financial literary talks by OCBC Bank staff volunteers to learn more about money management.

Do I really need insurance for my smartphone?

You may have only paid $200 for your latest smartphone, but if you had to replace that device before you are eligible for a subsidy from your carrier it cost your more than $600. Is it worth it to get device insurance?

That's the question I answer this time in Ask Maggie. I also offer some advice to an Apple iPhone fan who wants to know if he should wait for the next iPhone rumored to be out in June or July.

To buy insurance or live dangerously without?

Dear Maggie,
I am getting my son an
iPhone 5 for Christmas. I was wondering if I should also consider getting an insurance policy for the phone. Is it a good idea or a waste of money? Would I need to get Apple Care in addition to an insurance plan? And do you think I should get the insurance from a carrier or through a third party company?

Thanks,
Karen

Dear Karen,
The problem with buying any kind of insurance is that you simply don't know what will happen in the future. If your son's new iPhone is lost, stolen or damaged in the first few months of owning it, then it's a terrific bargain. But if he goes two years with not so much as a scratch on his precious new gadget, it's a waste of money.

Some people would rather save the money they'd spend on the insurance premiums and deductible, and hope nothing bad happens to their gadget. While others would prefer to have the peace of mind that comes with knowing their device can be replaced right away without having to pay full price for a new device.

The first thing you need to figure out is how much insurance will cost you and what it will cover. As you alluded to in your question, there are several options for purchasing smartphone and other gadget insurance. Wireless operators offer insurance plans as do third party companies. There are also extended warranty plans from device makers like Apple or from retailers like Best Buy, that typically cover mechanical defects to the device and may on some occasions cover some accidental damage coverage. But these programs typically do not cover you for a lost or stolen device.

In general, insurance plans will offer more coverage than an extended warranty. Here are a few things that many insurance policies will likely cover:

• Accidental damage (including shattered screens and liquid damage)
• Loss
• Theft or burglary
• Mechanical breakdown or malfunction beyond the manufacturer warranty

Some insurance policies may also cover things like credit monitoring as well as lock, wipe and locate services if your device is lost or stolen.

Every insurance policy will also include a fee or premium. And they all have a deductible. The fees and deductibles often depend on what kind of device you are insuring. Be aware that many policies charge higher premiums and have higher deductibles for the Apple iPhone as compared to other smartphones.

So make sure you double check the policy to see what the fees and deductibles are. Before you sign up for any insurance, you should check the specifics and fine print to see what is and is not covered.

To get you started on your search, here's a little information about a few options.

AT&T and Verizon Wireless offer insurance for the iPhone. But Sprint, which offers an insurance plan for other smartphones, does not offer a policy for the iPhone. T-Mobile, which doesn't offer the iPhone on its network, also does not have a policy that would cover the iPhone.

There are also insurance policies from third party companies you may want to consider. One such company is called ProtectYourBubble.com. It offers insurance for the iPhone as well as other gadgets. This company offers a 10 percent discount for additional policies you have either on other iPhones or on other gadgets.

Here's a quick look at the offers:

AT&T

Premium: $6.99 per month

Deductible: $199

Verizon Wireless

Premium: $9.99 per month

Deductible: $169 for 8GB, 16GB
iPhone 4, 16GB
iPhone 4S and, 8GB, 16GB iPhone 5 and $199 for 32GB iPhone 4 and 32GB, 64GB iPhone 4S and 32GB, 64GB iPhone 5

Protect Your Bubble

Premium: $7.99 per month

Deductible: $120 (Other smartphones have a deductible of $100.)

Which insurance plan is better? As you can see from the information listed above, Verizon has the most expensive insurance plan. Two years of premiums, plus the deductible will set you back $410. AT&T's premiums and deductible are $368 for the iPhone. And Protect Your Bubble's total comes to $312.

Are any of these policies really worth the cost? Again, it's hard to answer this question since it really depends on how likely it is that you'll need the insurance versus how much risk you're willing to live with if you don't get any insurance.

Remember that if you have to replace the device before your son is eligible for a new contract, it will cost you between $649 to $849 to replace his iPhone with a new iPhone 5 depending on the model you select. You may be able to get a used or refurbished iPhone for a bit less, but iPhones hold their value pretty well, so you will likely still end up paying several hundred dollars to get the same device.

Personally, I am a bit of a cheapskate. And I'm willing to take the risk of something happening to my device. I have never had insurance on any of my smartphones. And (knock on wood) I have never had a cracked screen or a device damaged by water or any other liquid. My iPhone 3G was stolen out of my backpack when I was playing in a flag football game a few years ago, but I was eligible for an upgrade from my carrier, so I only ended up paying $200 for a new phone anyway.

That said, I may soon be one of the few people who does not get insurance for my smartphone. According to Stephen Ebbett of Protect Your Bubble, 45 percent of smartphone subscribers have insurance for their devices. And he said that his company is seeing more and more people sign up for coverage.

"Our sales are growing week on week," he said. "We've been very encouraged by people recognizing the value of their smartphone in their lives. It's not just the cash value of their devices, but the fact that they really can't live without their smartphone for a week."

What about Apple Care?

Apple's AppleCare+ program costs $99 and extends the warranty of the iPhone for another year. The plan covers all repair coverage and technical support. And it also covers up to two incidents of accidental damage, each with an additional cost of $49.

While Apple Care+ is considerably less expensive than the insurance plans, you must remember that it is essentially an extended warranty. And it does not cover you if the device is lost or stolen. For iPhone users, this is a particularly important distinction since iPhone thefts are on the rise. The New York City Police Department said earlier this year that iPhone and iPad thefts went up 40 percent between January and the end of September.

Why? Compared to other gadgets, iPhones have high resale values, so they are often a target for thieves.

Do you need Apple Care+ in addition to insurance? The short answer to that question is no. The insurance policy for the phone will likely cover the same types of technical and accidental damage that the Apple Care+ service offers. The only thing you may lose by forgoing Apple Care+ is online and telephone technical support from Apple. But you should still be able to get some tech support from the Genius bar at your local Apple store. And your son's iPhone will be covered under the regular warranty for the first year that he owns it.

I hope this advice was helpful. And good luck! Happy holidays!

Should I wait for the next iPhone?

Dear Maggie,
I am in need of a new phone (currently using Blackberry Bold 9930 from Sprint) and would like to get the new iPhone. Here is the issue - as a guy who likes to have all the latest and greatest tech I'm rather scared to buy the iPhone 5 with all the "iPhone 5S" rumors that just started. I know it is pretty much impossible to stay up to date with every piece of technology (especially phones) . But if I am going to upgrade I would at least like the newest iteration. So what do you think about these rumors? Any chance that these will be true (it seems nearly every Apple rumor comes true these days)? Should I wait until June/July or just go ahead and get the iPhone 5 that is available now? Lots of questions I know, but these are confusing times.

Thanks in advance,
Jordan

Dear Jordan,
As you mentioned in your question, it is almost impossible to stay up to date with every piece of technology. So my recommendation to you is to not even try to play that game. The soonest we'd likely see an iPhone 5S, if it even exists, is June. That's is still half a year away. That's a long time in the fast-paced smartphone market.

Earlier this month, French Web site Nowhereelse.fr spotted alleged pictures of the next iPhone, commonly referred to as the iPhone 5S, on a forum run by iPhone5parts.net.

It sounds like you need a new smartphone now. So I'd recommend that you stop waiting and purchase a phone that you like right now. If a new iPhone comes out in six months, you could always sell it and still make bake a good portion of your money, which you could put toward a new iPhone.

Good luck with your decision.

Space Pictures This Week: Frosty Mars, Mini Nile, More

Photograph by Mike Theiss, National Geographic

The aurora borealis, also known as the northern lights, illuminates the Arctic sky in a recent picture by National Geographic photographer Mike Theiss.

A storm chaser by trade, Theiss is in the Arctic Circle on an expedition to photograph auroras, which result from collisions between charged particles released from the sun's atmosphere and gaseous particles in Earth's atmosphere.

After one particularly amazing show, he wrote on YouTube, "The lights were dancing, rolling, and twisting, and at times looked like they were close enough to touch!" (Watch his time-lapse video of the northern lights.)

School Shooting: Officials Seek Details on Gunman

The FBI is in at least three states interviewing relatives and friends of the elementary school gunman who killed 20 children, seven adults and himself, trying to put together a better picture of the shooter and uncover any possible explanation for the massacre, ABC News has learned.

The authorities have fanned out to New Jersey, Connecticut and Massachusetts to interview relatives of Adam Lanza, 20, and his mother, who was one of Lanza's shooting victims.

The victims died Friday when Lanza invaded Sandy Hook Elementary School in Newtown, Conn., and sprayed staff and students with bullets, officials said. Lanza also was found dead in the school.

Lt. Paul Vance said 18 children died in the school and two more died later in a hospital.

Six adults also were slain, bringing the total to 26. Among them was the school's principal, Dawn Hochsprung, multiple sources told ABC News. Another adult victim was teacher Vicki Soto, her cousin confirmed.

In addition to the casualties at the school, Lanza's mother, Nancy Lanza, was killed in her home, federal and state sources told ABC News.

According to sources, Lanza shot his mother in the face, then left his house armed with at least two semi-automatic handguns, a Glock and a Sig Sauer, and a semi-automatic rifle. He was also wearing a bulletproof vest.

Lanza then drove to the elementary school and continued his rampage, authorities said.

It appeared that Lanza died from what was believed to be a self-inflicted gunshot wound. The rifle was found in his car.

"Evil visited this community today," Gov. Dan Malloy said at a news conference Friday evening.

CLICK HERE for more photos from the scene.

In the early confusion surrounding the investigation, federal sources initially identified the suspect as Adam's older brother Ryan Lanza, 24. Identification belonging to Ryan Lanza was found at the shooting scene, federal sources told ABC News.

Ryan Lanza soon took to Facebook to say he was alive and not responsible for the shooting. He later was questioned by police.

During the rampage, first-grade teacher Kaitlin Roig, 29, locked her 14 students in a class bathroom and listened to "tons of shooting" until police came to help.

"It was horrific," Roig said. "I thought we were going to die."

She said that the terrified kids were saying, "I just want Christmas. ... I don't want to die. I just want to have Christmas."

A tearful President Obama said Friday that there was "not a parent in America who doesn't feel the overwhelming grief that I do."

The president had to pause to compose himself after saying these were "beautiful little kids between the ages of 5 and 10."

As he continued with his statement, Obama wiped away tears from each eye. He has ordered flags flown as half staff.

It is the second worst mass shooting in U.S. history, exceeded only by the Virginia Tech shooting in 2007 when 32 were killed before the shooter turned the gun on himself. The carnage in Connecticut exceeded the 1999 Columbine High School shooting in which 13 died and 24 were injured.

Friday's shooting came three days after masked gunman Jacob Roberts opened fire in a busy Oregon mall, killing two before turning the gun on himself.

The Connecticut shooting occurred at the Sandy Hook Elementary School, which includes 450 students in grades K-4. The town is located about 12 miles east of Danbury, Conn.

The massacre prompted the town of Newtown to lock down all its schools and draw SWAT teams to the school, authorities said.

Bell tolls for Beijing's Drum Tower homes

BEIJING - China's capital is to destroy swathes of ancient courtyard homes surrounding a 13th-century landmark in what is being called an effort to preserve Beijing's historical legacy, residents said Friday.

Large numbers of hutong homes, some of them dating back to the Qing dynasty, will be demolished around the Drum and Bell Towers -- a tourist hotspot in Beijing's historic centre -- to make way for a large plaza, they said.

Notices for the "destroy and evict" project are plastered throughout the quarter, dated Wednesday and saying the work was due to be completed by February 24.

Besides protecting the historic legacy of the capital, the project is also aimed at restoring and repairing old and dilapidated buildings, the notices said.

Forced evictions are a major source of unrest in China. Ordinary citizens routinely accuse local officials and developers of cashing in on a property boom by clearing away longstanding residents to pave the way for new projects.

Destroying old homes in central Beijing has particular sensitivity. Critics say new development projects rob the capital of its cultural legacy.

"We have been hearing this was going to happen for years, but now that the notices are up there is not much you can do but leave," said souvenir shop seller Ma Yong.

"When I first saw the notices I felt nothing but despair."

Besides having her rented shop torn down, Ma's small home nearby, where she lives with her retired husband, will also be flattened.

Residents must negotiate compensation with the newly set up "destroy and evict" office near the Bell Tower, with compensation beginning at around 40,000 yuan (US$5,800) per square metre.

Between 130 and 500 homes are to be destroyed, state press reports said.

Officials refused to answer questions when approached by AFP.

"A lot of people are opposed to the campaign, 40,000 yuan per square metre is too cheap, especially with the price of housing in Beijing sky-rocketing," said the manager of a coffee shop near the Drum Tower, who gave her surname only as Wang.

"People are already asking for 150,000 yuan per square metre," she said.

Others said they were happy with the compensation.

"We took the money," said Zhou Li, 51, who was to move out to the suburbs with his elderly parents this weekend after living most of his life near the Bell Tower.

How Google is taking the Knowledge Graph global

The Knowledge Graph became available in seven new languages this month.

(Credit:
Google)

Earlier this month, Google shared a fascinating statistic. The number of items in the company's Knowledge Graph -- its database of people, places, and things, and the connections between them -- had tripled in size over its first seven months in the wild, to 18 billion facts.

Up until this month, though, those facts were available only in English. It wasn't until December 4 that Google made the Knowledge Graph truly global, by introducing it in seven new languages: Spanish, French, German, Portuguese, Japanese, Russian, and Italian.

The project to make Knowledge Graph content available in so many new languages simultaneously was no small feat. Even in English, creating an easily searchable database of relationships is fraught with potential problems. If I search for "giants," do I mean the baseball team, the football team, or enormous people? Using a variety of signals, Google makes its best guess -- and then presents its findings in a handy panel on the right-hand side of the results page. (Or it will display a panel asking if you want results for baseball or football.)

Now imagine running that same query in other languages. What does a user searching for "giants" in French want? How about in Italian? Japanese?

The task of localizing Google's Knowledge Graph fell in part to Tamar Yehoshua, who oversees Google's efforts to take search international. What roadblocks has Google found along the way? Here are a few.

Google's Tamar Yehoshua.

Google)

Figuring out where you are. This challenge predates the Knowledge Graph, but determining a user's location is still the foundation of all localization. The most important signal is the Google domain you're using -- .com indicates the United States, .co.jp indicates Japan, and so on. From there. Google looks at your IP address, the language of your browser, and the language you're searching in. The idea is to drill down to your current city so that results are as local as possible. (Using the settings page, users can search as if they were in another city.)

This has a big impact on search results. Search "UPC" on Google.com and you'll see information about universal product codes. But take the same search to Google.ie, the company's Irish domain, and the query brings up results for UPC Ireland -- the biggest cable television provider in that country.

Making answers locally relevant. Knowing where users are is only the first step. From there Google has to consider what sorts of things other people in that location tend to search for, and offer results accordingly. This is perhaps the Knowledge Graph's biggest challenge as it expands around the globe, because a query that Google can answer well in English might not be useful in another country. Getting it right means more than performing a basic translation.

"We want to understand entities that are culturally relevant as well," Yehoshua said. "In most software programs, you translate search strings -- all you have to do is translate a string to make your product work in another locale. In this instance, with the Knowledge Graph, we want to make sure the entities are culturally relevant."

Hence a search for "sumo" brings up much more detailed information about the sport in a Japanese-language search than it does in an English language search. (In San Francisco, naturally, the first search result is a software startup.)

Making the Knowledge Graph work in other languages means teaching Google about the cultural traditions that exist everywhere it is used, and generating results that are useful to local residents. It's a tall order.

Different cultures want different answers. Even when language isn't a factor in Knowledge Graph queries, Google still finds that other cultures have different expectations when they search.

Take the search for "Barack Obama." In the United States, the Knowledge Graph shows facts like his name, age, children, and education. Do the same search in Japan, though, and you'll find another fact, prominently displayed: the president's height (6'1"). It turns out that Japanese queries about the president involve a disproportionate amount of queries about how tall Obama is, and so the Knowledge Graph has to account for that.

Doing all this mostly with algorithms. Google has localization teams around the world that help bring the service to new languages. But the Knowledge Graph isn't a handcrafted guide to world culture.

"It is predominantly algorithmic," Yehoshua said.

The machine learning involved in getting Google to understand the relative importance of millions of culturally distinct subjects in real time is not trivial. As Yehoshua illustrated for me, expanding into new languages results in all sorts of new complications. But if Google is ever going to transform into the "Star Trek" computer, this is how it has to begin. And tackling those complications has another benefit for Google: it makes it harder for challengers to compete. And with Bing now adding Knowledge Graph-like features to its own search results page, it's clear that competitors will be following close behind.

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.

Critics Faulted Rice's Work on Benghazi, Africa

United Nations Ambassador Susan Rice removed herself from possible consideration as secretary of state after becoming yet another player in the divide between the left and right.

Rice, who withdrew her name Thursday, has faced months of criticism over how she characterized the Sept. 11 attack on a U.S. consulate in Benghazi, Libya. She also has come under fire for her approach to dealing with African strongmen.

Rice became a target for conservatives when she went on Sunday morning current affairs shows such as ABC News' "This Week" following the Benghazi attack and failed to characterize it as a pre-meditated act of terror. Instead, she said it was a spontaneous response to an anti-Islam film produced in the United States and cited in the region as an example of anti-Islamicism in the West.

After it became clear that Rice's assertions were untrue and elements of the Obama administration may have known that to be the case, Republican Sens. Lindsey Graham, John McCain and Kelly Ayotte said they would do whatever they could to block Rice's possible nomination to replace Hillary Clinton as secretary of state.

"This is about the role she played around four dead Americans when it seems to be that the story coming out of the administration -- and she's the point person -- is so disconnected to reality, I don't trust her," Graham said. "And the reason I don't trust her is because I think she knew better. And if she didn't know better, she shouldn't be the voice of America."

Members of the administration defended Rice. At his testimony before Congress, Gen. David Petraeus, the former CIA director, said Rice was speaking from unclassified talking points given to her by the CIA.

Senate Intelligence Committee Chairwoman Dianne Feinstein, D-Calif., reiterated what Petraeus said outside his closed-door hearing before the Senate.

"The key is that they were unclassified talking points at a very early stage. And I don't think she should be pilloried for this. She did what I would have done or anyone else would have done that was going on a weekend show," Feinstein said. "To say that she is unqualified to be secretary of state, I think, is a mistake. And the way it keeps going, it's almost as if the intent is to assassinate her character."

Minutes after she announced her withdrawal from the process, Graham tweeted, "I respect Ambassador Rice's decision."

McCain's office released a paper statement saying, "Senator McCain thanks Ambassador Rice for her service to the country and wishes her well. He will continue to seek all the facts surrounding the attack on our consulate in Benghazi that killed four brave Americans."

Over the last few weeks, criticism of Rice had grown beyond her response to Benghazi to include a closer scrutiny of her work in Africa, where she had influence over U.S. policy during the Clinton administration.

Critics of her Africa dealings were not partisan -- but included human rights workers, journalists and some Africans themselves.

Among the most serious critiques was the accusation that she actively protected Rwandan President Paul Kagame and senior members of his government from being sanctioned for funding and supporting the rebels that caused Eastern Congo's recent violence.

Search for aliens poses game theory dilemma

SENDING messages into deep space could be the best way for Earthlings to find extraterrestrial intelligence, but it carries a grave risk: alerting hostile aliens to our presence. Game theory may provide a way to navigate this dilemma.

So far the search for extraterrestrial intelligence (SETI) has mostly been restricted to listening for signs of technology elsewhere. Only a few attempts have been made to broadcast messages towards distant stars. Many scientists are against such "active" SETI for fear of revealing our presence. If all aliens feel the same way then no one will be broadcasting, and the chance of detecting each other is limited.

To weigh up the potential losses and gains, Harold de Vladar of the Institute of Science and Technology Austria in Klosterneuburg turned to the prisoner's dilemma, a game-theory problem in which two prisoners choose between admitting their shared crime or keeping quiet, with different sentences depending on what they say. An individual prisoner gets off scot free if they rat on a partner who remains silent, with the silent partner getting a maximum sentence. If they both rat on each other, each gets a medium sentence. By contrast, if both stay silent, both get token sentences - the best overall result.

De Vladar reasoned that the SETI dilemma is essentially the same, but reversed. Mutual silence for prisoners is equivalent to mutual broadcasting for aliens, giving the best results for both civilisations. And while a selfish prisoner rats, a selfish civilisation is silent, waiting for someone else to take the risk of waving "Over here!" at the rest of the universe.

This led de Vladar to apply the mathematics of the prisoner's dilemma to SETI (International Journal of Astrobiology (IJA), doi.org/jx7). In the classic version of the prisoner's dilemma, each selfishly rats on the other. But as we do not know the character of any aliens out there, and as it is difficult to put a value on the benefits to science, culture and technology of finding an advanced civilisation, de Vladar varied the reward of finding aliens and the cost of hostile aliens finding us. The result was a range of optimal broadcasting strategies. "It's not about whether to do it or not, but how often," says de Vladar.

One intriguing insight was that as you scale up the rewards placed on finding aliens, you can scale down the frequency of broadcasts, while keeping the expected benefit to Earthlings the same. Being able to keep broadcasts to a minimum is good news, because they come with costs - rigging our planet with transmitters won't come cheap - and risk catastrophic penalties, such as interstellar war.

Seth Shostak of the SETI Institute in Mountain View, California, says that game theory is a good approach but that there are too many unknowns. Perhaps aliens are not actively broadcasting because they don't need to. Shostak has recently shown that a civilisation even slightly more advanced than ours could use its sun as a "gravitational lens". Such a lens could detect the lights of New York City from up to 500 light years away, once the light has had time to travel that far (IJA, doi.org/jx8). And there are certainly alien star systems that are closer to us than that.

Earth has also been accidently leaking radio and TV signals for the past century, which may have already been picked up. "Any society at least a few centuries beyond the invention of radio will recognise that deliberate transmissions are not the way they will be found," says Shostak. Quick, turn off those lights!

Cricket: Clarke vows no complacency against Sri Lanka

HOBART, Australia: Skipper Michael Clarke has vowed there will be no complacency in the Test series with Sri Lanka, insisting Australia will improve on their recent performances against South Africa.

The Australians had the better of the opening two Tests against the world number one Proteas only to be crushed by 309 runs in the series decider in Perth last week.

Sri Lanka are ranked sixth in the world, have not won in 10 Tests in Australia over 25 years and are rated outsiders to upset Clarke's team in the three-Test series, beginning in Hobart on Friday.

Former Australian quick Rodney Hogg has rubbished the Sri Lankan attack as the "worst ever" to come to Australia, with Nuwan Kulasekara, Shaminda Eranga and Chanaka Welegedara only having 38 Tests and 99 wickets between them.

Clarke said the third-ranked Australia were focused only on beating Sri Lanka in the first Test since 168-Test great Ricky Ponting's retirement.

"The opposition is irrelevant to how you judge yourself as players," he said.

"Our goal is not to come out and play the same way against Sri Lanka as we did against South Africa.

"We have to learn from that series, take the positives - and I thought there were a lot of positives - and the areas where we need to get better, we need to make sure we do that.

"I'm sure that if we improve on the series against South Africa, we'll continue to have success."

Mitchell Johnson has been left out for the Hobart Test with Australia opting for the pace attack of Ben Hilfenhaus, Peter Siddle and left-armer Mitchell Starc, supplemented by swing bowler Shane Watson and spinner Nathan Lyon.

Recalled Phil Hughes will bat at number three with Watson at four while Clarke and veteran Mike Hussey stay at five and six in the Australian line-up now missing Ponting.

"The strength and advantage we now have in our top four is that all four have opened the batting for Australia," Clarke said.

"So against the new ball they will be very well suited and if we lose early wickets we're still very capable against the new ball which is a real positive."

Clarke also defended the daredevil batting style of opener David Warner, whose second innings dismissal for 29 against South Africa in Perth triggered criticism.

"The one thing we have to understand about Davey, is that the same ball that got him out in Perth, we were all applauding in Adelaide when it went over slips for four. That's the way he plays," he said.

"The only thing I continue to say to Davey is to make sure his intent is there. When the intent is there, his defence is better, his shot selection is better.

"Sometimes it's not going to look great when he gets out, but on the other hand he has the X-factor. He takes the game away from the opposition in the first session of a Test match ... there's not many players in the world that have that talent."

Clarke rated Warner's unbeaten 123 in last year's Hobart Test against New Zealand as among the dashing left-hander's finest.

"I think one of Davey's greatest innings was the hundred he scored here against New Zealand in really tough batting conditions. He still had that intent, even though the wicket was doing a lot. His shot selection was perfect. "In a perfect world, you'd love to bottle that, but you have to have a bit of give and take with Davey."

Sprint says it wants to buy out Clearwire for $2.1 billion

Talks between Sprint Nextel and Clearwire are heating up.

Sprint confirmed via a filing with the Securities and Exchange Commission made public today that it was in talks with Clearwire to buy out the remaining stake in the upstart wireless provider that it didn't already own.

The company said it believed that it would cost $2.1 billion to buy out the remaining 49 percent stake in Clearwire, valuing the company at $2.90 a share, or a 5.5 percent premium to its closing price on Wednesday.

Clearwire also submitted a filing confirming the talks, but declined to provide any more details, only noting that a deal isn't guaranteed.

A deal would be a long-time coming for the two companies, which have essentially been tied at the hip for years. Sprint is Clearwire's largest shareholder and customer, yet despite majority control in shares, Sprint did not have control of the board or the direction of the company.

A takeover would make for a cleaner deal for Softbank, which intends to take full control of Sprint next year as part of a deal to pump capital into Sprint and reinvigorate the carrier.

Speculation about talks between the two companies isn't new, and there were reports earlier this week that the two were in negotiations.

Clearwire currently supplies 4G WiMax service to its customers, but is in the middle of its transition to the newer 4G LTE technology, which the rest of the industry has moved on to. Sprint, meanwhile, has reduced its use of Clearwire's WiMax network to legacy WiMax smartphones and its prepaid business, opting to use its own 4G LTE network for its newer smartphones.

The structure in which Sprint owns a significant chunk of Clearwire was set up four years ago as part of a way for Sprint to offload its WiMax operations. At the time, Sprint had managed to sign up other big name partners such as Intel, Time Warner Cable, and Comcast as shareholders.

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."

McAfee Returns to US, Admits Playing 'Crazy Card'

John McAfee's month-long international run from police through two Central American nations ended with a flight to Miami, where the businessman who says he abandoned his fortune admitted to playing the "crazy card."

As a gaggle of media waited near several exit doors at the airport Wednesday night, federal authorities whisked the founder of McAfee anti-virus software off the plane and into a van.

"They said, 'Mr. McAfee, please step forward,'" McAfee, 67, later told ABC News exclusively overnight at a Miami Beach hotel. "I was met by a dozen or maybe fewer officers. I said, 'Am I arrested?' They said, 'No, sir, I am here to help you.' That felt the best of all."

He eventually snuck out of the airport in a cab and headed to South Beach. After walking down famed Ocean Drive to the bewilderment of tourists and eating sushi, his first meal in three days, he sat down with ABC News and admitted to playing the "crazy card" and says he is broke.

"I have nothing now," McAfee said. He claims he left everything behind in Belize, including $20 million in investments and about 15 properties. "I've got a pair of clothes and shoes, my friend dropped off some cash."

Just hours earlier, the self-made millionaire was deported by Guatemalan police who forced him aboard his U.S.-bound flight away from the home and the two women he said he loves. After he arrived on South Beach, he said, a mysterious "Canadian friend" ordered another man he'd never met to drop off a wad of fresh $5 bills that McAfee later displayed to ABC News, pulling them from his coat pocket.

Software Founder Breaks Silence: McAfee Speaks on Murder Allegations Watch Video

He says he left his fortune, including a beachfront compound, behind after his neighbor Greg Faull was found shot to death in Belize on Nov. 10.

Belize officials said he isn't a suspect, but when they asked to question him, McAfee disguised himself and ran.

After three weeks ducking authorities in Belize, by hiding in attics, in the jungle and in dingy hotels, he turned up in Guatemala Dec. 3.

Barely a day later he was detained for entering the country illegally. As Guatemala officials grappled with how to handle his request for asylum and the Belize government's demand for his deportation, McAfee fell ill. The mysterious illness, described by his attorney alternately as a heart ailment or a nervous breakdown, led to a scene with reporters chasing his ambulance down the narrow streets of Guatemala City and right into the emergency room, where McAfee appeared unresponsive.

He now says it was all a ruse:
"It was a deception but who did it hurt? I look pretty healthy, don't I?"

He says he faked the illness in order to buy some time for a judge to hear his case and stay his deportation to Belize, a government he believes wants him dead. When asked whether he believes Belize officials where inept, he didn't mince words.

"I was on the run with a 20-year-old girl for three and a half weeks inside their borders and everyone was looking for me, and they did not catch me," he said. "I escaped, was captured and they tried to send me back. Now I'm sitting in Miami. There had to be some ineptness."

The man who many believe only wants attention answered critics who called his month-long odyssey and blog posts a publicity stunt by simply saying, "What's a better story, millionaire mad man on the run. You [the media] saved my ass. Because you paid attention to the story. As long as you are reporting, it is hard to whack somebody that the world is watching."

He denies any involvement in his neighbor's death but adds that he is not particularly concerned about clearing his name. He is focused on getting his 20-year-old and 17-year-old girlfriends out of Belize and says he has no idea what he'll do next, where he'll live or how he'll support himself.

A deliberate language barrier

THE United States and Britain are two countries "divided by a common language", George Bernard Shaw allegedly quipped.

This statement, amusingly paradoxical on the face of it, might be more accurate than it seems. On "War of words: The language paradox explained", evolutionary biologist Mark Pagel argues that languages proliferate to differentiate competing groups.

If so, a shared tongue is not what the transatlantic rivals would have wanted. Sure enough, they quickly diverged; some of the differences between US and British spellings seem to have arisen as part of a knowing attempt to widen the gulf.

So perhaps it was Shaw's fellow wit Oscar Wilde who got closer to the mark when he observed in his 1887 story The Canterville Ghost that "we have really everything in common with America nowadays, except, of course, language".

Asia shares gain, unmoved by North Korea rocket launch

HONG KONG: Asian markets rose on Wednesday as dealers welcomed signs of progress in US fiscal cliff talks and upbeat data from Germany and Spain, while shrugging off news of North Korea's rocket launch.

With investors becoming more confident the safe-haven yen came back under pressure ahead of a general election in Japan on Sunday and expectations of more monetary easing by the country's central bank.

Tokyo rose 0.59 percent, adding 56.14 points to 9,581.46, Seoul was up 0.55 percent, gaining 10.82 points to 1,975,44, and Sydney climbed 0.17 percent to a 17-month high, adding 7.8 points to 4,583.8.

Hong Kong ended up 0.80 percent, adding 179.41 points to close at 22,503.35, while Shanghai was 0.39 percent, or 8.03 points, higher at 2,082.73

US President Barack Obama and Republican House Speaker John Boehner have swapped new offers to avoid the fiscal cliff of huge tax hikes and spending cuts due to come into effect on January 1, according to sources on both sides.

It fuelled hopes that the two, who have been at loggerheads over plans to increase taxes on the rich and slashing aid to Medicare, could come to an agreement.

If a deal is not reached by the New Year, the package currently in place is widely expected to send the economy into recession.

Markets are also eyeing a meeting of the Federal Reserve policy committee, which is to decide on what action to take as the end approaches of its "Operation Twist" -- selling short-term debt to buy longer-term debt.

There are expectations that policymakers will replace it with more outright bond purchases, or "quantitative easing", aimed at lowering interest rates to encourage businesses to invest and hire.

Buying support was also provided by positive numbers from Germany, where investor sentiment in Europe's key economic machine hit a seven-month high on hopes it will dodge recession.

The confidence index from the ZEW economic institute surged to 6.9 points in December from minus 15.7 in November. Forecasts had been for a reading of minus 11.3.

It was the highest reading since May and the first time since then that the index has been in positive territory.

Spain also enjoyed a successful Treasury bond auction, easing fears over its ability to raise cash to pay its bills.

Traders on Wall Street ended on a positive note. The Dow rose 0.60 percent, a fifth straight day of gains, while the S&P 500 added 0.65 percent and the Nasdaq climbed 1.18 percent.

Confidence in "riskier" assets hit the yen, usually the go-to unit in times of uncertainty, in US trade on Tuesday and it remained under pressure in Asia Wednesday.

The dollar rose to 82.77 yen, compared with 82.51 yen in New York, while the euro was at 107.70 yen from 107.28 yen. That compares with 82.36 yen and 106.68 yen in Asia Tuesday.

The euro bought $1.3010 Wednesday, from $1.3003 in New York.

The yen has come under pressure in recent weeks ahead of Sunday's polls widely expected to see Prime Minister Yoshihiko Noda's Democratic Party of Japan beaten by the Liberal Democratic Party, which is headed by Shinzo Abe.

Abe, a former prime minister, has promised to push a more aggressive monetary easing policy to jumpstart the economy.

Investors shrugged off news that North Korea had fired its rocket, which critics insist was being used as a disguised ballistic missile test.

Previous launches and nuclear tests have led to an initial asset sell-off owing to geopolitical fears, but regional markets remained up in early trade.

"Frankly, it was almost a non-event," Norihiro Fujito, senior investment strategist at Mitsubishi UFJ Morgan Stanley Securities, told Dow Jones Newswires.

On oil markets New York's main contract, West Texas Intermediate for delivery in January, edged up 23 cents to $86.02, and Brent North Sea crude for January added 44 cents at $108.45.

Gold was at $1,713.23 at 0805 GMT compared with $1,709.35 late on Tuesday.

In other markets:

-- Taipei rose 1.0 percent, or 76.5 points, to 7,690.19.

HTC rose 4.05 percent to Tw$282.5 while TSMC was 0.1 percent higher at Tw$98.4.

-- Manila closed 0.20 percent lower, dipping 11.71 points to 5,819.79.

Ayala Corp. fell 3.22 percent to 510 pesos while Philippine Long Distance Telephone slipped 1.29 percent to 2,596 pesos.

-- Wellington ended 0.77 percent, or 30.92 points, lower at 3,995.26.

Telecom fell 2.0 percent to NZ$2.19, Fletcher Building also lost 2.0 percent to NZ$8.28 and Contact Energy was down 2.1 percent at NZ$5.10.

Flickr's new iPhone app puts mobile front and center

The new iPhone app from Flickr attempts to make the photo-sharing site fully usable with a smartphone.

(Credit:
Yahoo)

Flickr released an overhauled iPhone app today, capping a year of effort to reclaim its lost glory with software that it believes will become central rather than peripheral to using the photo-sharing site.

The new app is designed to show off individual photos better, to ease sign-up for new users, to speed photo browsing, and to improve discovery. Better smartphone support was critical, given how much activity has moved to mobile apps.

"Engagement to a high percentage is happening on mobile," said Markus Spiering, head of the Flickr product at Yahoo. "It really brings Flickr into the palm of your hand."

Photos are of course at the center of the new app. Scrolling vertically shows recent photos posted by Flickr members' contacts; if you want to see more from a particular contact, you can scroll horizontally from an image.

Looking at an individual photo's page, you can read and write comments, double-tap to mark it as a favorite, rotate the phone to landscape orientation to see a high-resolution, full-screen version, and tap an information button to virtually flip over the photo to see where it was taken, what groups and sets it belongs to, and other details.

Tabs at the bottom of the app's screen let you navigate among different sections to reach Flickr services. For example, one lets you browse photos from your contacts and groups; another is for discovering photos that are interesting or were taken nearby; and another is for delving into an individual's photo stream. You can also take photos with some detailed camera controls, and uploading them lets you add title, caption, and location details.

More apps will come.

"We're doing iPhone in this case first, because it's the most popular camera on Flickr now," Spiering said. For example, 3,817 Flickr users uploaded 62,839 images yesterday taken with an
iPhone 4S. But
Android and
tablet apps will follow.

"We are planning shortly after the iPhone launch to bring the experience also on Android -- a consistent experience that feels natural and native to the platform," he said. "Going forward there should not be a difference between where you use Flickr," he said, mentioning smartphones, tablets, and desktop computer.

Today, Flickr doesn't offer apps for iPad or Android tablet, though of course it can be used with the browser.

Flickr pioneered online photography, letting people share photos, comment on them, create and join groups for particular areas of interest, and use third-party software and services to use the service. It's no wonder Yahoo acquired the start-up.

In recent years, though, it's lost some of its luster as people moved online photo activity to sites with a stronger social fabric: Facebook is a natural vehicle for sharing photos with social contacts, Facebook's Instagram has successfully blended photography with social sharing, and Twitter is angling to get in on the action as well.

Perhaps because Yahoo doesn't really have social network turf to defend, Flickr has one interesting differentiator over rivals: it's relatively open. In contrast, Facebook and Twitter, which block Web crawlers, are often invisible in search engines. Twitter and Instagram are building barriers to photo sharing. Flickr, though, can be a repository for Instagram photos, and it's got a built-in mechanism for sharing to Facebook, Twitter, Tumblr, Google's Blogger, and more. And its application programming interface (API) means anything from Apple TVs to Windows 8 can integrate with Flickr's online repository.

And Flickr is still relevant if no longer cutting-edge, with 85 million active users per day.

Flickr also continued its Web site retooling, cleaning up site navigation and bringing the "justified" view that fills the screen with wall-to-wall photos to more areas of the site, Spiering said. Yahoo tests showed that user activity increased significantly with the new Web site.

Best Space Pictures of 2012: Editor's Picks

Photograph courtesy Tunç Tezel, APOY/Royal Observatory

This image of the Milky Way's vast star fields hanging over a valley of human-made light was recognized in the 2012 Astronomy Photographer of the Year competition run by the U.K.’s Royal Observatory Greenwich.

To get the shot, photographer Tunç Tezel trekked to Uludag National Park near his hometown of Bursa, Turkey. He intended to watch the moon and evening planets, then take in the Perseids meteor shower.

"We live in a spiral arm of the Milky Way, so when we gaze through the thickness of our galaxy, we see it as a band of dense star fields encircling the sky," said Marek Kukula, the Royal Observatory's public astronomer and a contest judge.

Cops Have Identity of Gunman in Oregon Shooting

A masked gunman who opened fire in the crowded Clackamas Town Center mall in suburban Portland, Ore., killing two individuals and seriously injuring a third before killing himself, has been identified by police, though they have not yet released his name.

The shooter, wearing a white hockey mask, black clothing, and a bullet proof vest, tore through the mall around 3:30 p.m. Tuesday, entering through a Macy's store and proceeding to the food court and public areas spraying bullets, according to witness reports.

"We have been able to identify the shooter over last night," Sheriff Craig Roberts told "Good Morning America" today.
"At this point in time, because of the investigation, we're actually doing supplemental search warrants, we're not able to release the name of the individual at point in time for the reason being that we don't want to jeopardize the investigation."

Police have not released the names of the two deceased. Clackamas County Sheriff's Department Lt. James Rhodes said authorities are in the process of notifying victims' families.

The injured victim has been transported to a local hospital, according to Clackamas County Sheriff Craig Roberts.

Nadia Telguz, who said she was a friend of the injured victim, told ABC News affiliate KATU-TV in Portland that the woman was expected to recover.

"My friend's sister got shot," Teleguz told KATU. "She's on her way to (Oregon Health and Science University hospital). They're saying she got shot in her side and so it's not life-threatening, so she'll be OK."

911 Calls From New Jersey Supermarket Shooting Watch Video

Witnesses from the shooting rampage said that a young man who appeared to be a teenager ran through the upper level of Macy's to the mall food court, firing multiple shots, one right after the other, with what is believed to be a black, semi-automatic rifle.

More than 10,000 shoppers were at the mall during the day, police said. Roberts said that officers responded to the scene of the shooting within minutes, and four SWAT teams swept the 1.4 million-square-foot building searching for the shooter. He was eventually found dead, an apparent suicide.

"I can confirm the shooter is dead of an apparent self-inflicted gunshot wound," Rhodes said. "By all accounts there were no rounds fired by law enforcement today in the mall."

Roberts said more than 100 law enforcement officers responded to the shooting, and at least four local agencies were working on the investigation, including the FBI and Bureau of Alcohol, Tobacco and Firearms, which is working to trace the shooter's weapon.

READ: Guns in America: A Statistical Look

"For all of us, the mall is supposed to be a place where we can take our families, especially during the holiday season," Roberts said. "Things like this are not supposed to happen."

Roberts also said that shoppers, including two emergency room nurses and one physician who happened to be at the mall, provided medical assistance to victims who had been shot. Other shoppers helped escort individuals out of the mall and out of harm's way, he said.

"There were a huge amount of people running in different directions, and it was chaos for a lot of citizens, but true heroes were stepping up in this time of high stress," Roberts said. "E.R. nurses on the scene were providing medical care to those injured, a physician on the scene was helping provide care to the wounded."

Mall shopper Daniel Martinez told KATU that he had just sat down at a Jamba Juice inside the mall when he heard rapid gunfire. He turned and saw the masked gunman, dressed in all black, about 10 feet away from him.

"I just saw him (the gunman) and thought, 'I need to go somewhere,'" Martinez said. "It was so fast, and at that time, everyone was moving around."

Martinez said he ran to the nearest clothing store. As he ran, he motioned for another woman to follow; several others ran to the store as well, hiding in a fitting room. They stayed there for an hour and a half until SWAT teams told them it was safe to leave the mall.

AC/DC's Highway to Hell sent via a drone's laser beam

Paul Marks, senior technology correspondent

(Image: David Thorpe/Rex Features)

What is it about technology and Aussie rock band AC/DC? In July a computer hack led to the band's track Thunderstruck belting out at top volume in an Iranian nuclear power plant. Now AC/DC's signature hit Highway to Hell is riding on a laser beam that's being bounced off a drone in mid-flight. When the beam is reflected to a ground sensor the full glory of the music is reconstructed without a cymbal crash out of place.

Don't worry, it's not a new sonic weapon. To make drones lighter and and operate longer reconnaissance missions without refuelling, Yoann Thueux and colleagues at EADS Innovation Works in Newport, UK, eschew the heavy radio equipment and antennas used to beam acquired video back to base. Instead, they are developing a laser reflector called Dazzle that can simply add the drone's acquired video data to a laser beam bounced off the craft's belly by a tracking system up to 2 kilometres away.

After the laser beam enters the reflector, it passes through a transparent switch, called a light modulator, that adds the digital zeroes and ones of the video data to the beam. The light then hits a mirror and is reflected back to the spot it came from - carrying the video data. The tech will allow a speed boost to 1 gigabit per second - easily allowing faster delivery of HD video, which struggles to top 20 megabits per second with radio frequencies.

The reflector and its ground UAV tracking system began tests on a disused runway at a former Royal Air Force base in Pershore, UK, last week. The first test aimed to see if the system could simply reflect an encoded laser beam from a moving eight-rotor helicopter drone, the Okto from Mikrocopter of Germany.

Thueux thought Highway to Hell a great choice of data to stream on the laser. "It was on my iPod and I thought it would be a good song to go first because I know it completely by heart. I'd be the first to tell if the technology was not working properly on playback."

So what tunes might will fly are next? "I happen to be in a band, so maybe one of our tracks," says Thueux. "But a colleague is also suggesting Fly Me To The Moon."

Malaysian customs seize record 24 tonnes of ivory

KUALA LUMPUR: Malaysian customs have seized 24 tonnes of unprocessed elephant tusks worth almost US$20 million, the largest haul in the country to date, officials said Tuesday.

Some 1,500 tusks hidden in two containers were discovered by customs officials at the country's main port of Klang, in the western state of Selangor.

The tusks had been hidden within pieces of timber inside the containers, which had originated from the west African nation of Togo.

State customs director Azis Yaacub said in a statement that the cargo had been transferred from one ship to another in Spain and was believed to be headed to China.

"The two containers were found to be filled with sawn timber. Inside the wood there were secret compartments that were filled with elephant tusks," he said.

The haul is worth 60 million ringgit, which amounts to US$19.6 million. Officials said that the seizure on December 7 was the fourth in the past year and was larger than the other three combined.

Wildlife trade-monitoring network TRAFFIC has described Malaysia as a major hub for illicit wildlife products.

International trade in elephant ivory was banned in 1990 with rare exceptions, such as auctions of tusks from elephants that have died naturally, or that have been seized from poachers in Namibia, Botswana and South Africa.

However, the ivory trade has grown globally since 2004, largely due to demand in China, where it is used in traditional medicine.

According to the World Wildlife Fund, African elephant populations may have been as high as five million in the first part of the 20th century, but their numbers could now be as low as 470,000.

Interest for premium-priced Apple TV high, analyst says

There's even more initial interest in an Apple-made television than there was for the iPhone and
iPad.

That's according to Morgan Stanley analyst Katy Huberty, who wrote in a note issued today that consumers were willing to pay a 20 percent premium and that there was twice the initial interest in purchasing Apple's mobile devices.

Speculation over the Apple iTV remains one of the hot topics as analysts, investors, and company observers look to the next big growth driver for the company. CEO Tim Cook dropped a hint during a recent interview, calling it "an area of intense interest."

It's an area of interest for Apple fans too, according to Huberty.

Apple, meanwhile, has remained mum on the subject, and even Cook said he wouldn't go further after dropping his hint.

Instead of focusing on content, which many believe has been a key hurdle for the introduction of an iTV, Apple could work on improving the operating system, improving the search, ease of use, interaction, and control of the television set, she said.

The television business could use a little innovation. Her survey found that 13 percent of the respondents didn't even know they owned a smart TV, and those that do actually connect their television to the Internet less than those without a smart TV.

"What's more, many consumers are willing to pay a meaningful premium for an Apple-branded Smart TV, a sign that consumers are not happy with current offerings," she said.

For Apple, the television business could mean an opportunity to ship 13 million units in the U.S., with consumers willing to pay $1,060 on average, representing a $13 billion revenue opportunity and $4.50 in earnings per share. Those figures could quadruple if Apple is successful overseas, Huberty said.

They survey found 47 percent are interested in purchasing an iTV, more than the 23 percent and 21 percent respectiv einterest for the iPhone and iPad. Part of the increase in the interest is due to the "halo effect" of having already owned an Apple product, Huberty said.

U.K. Dash for Shale Gas a Test for Global Fracking

Thomas K. Grose in London

The starting gun has sounded for the United Kingdom's "dash for gas," as the media here have dubbed it.

As early as this week, a moratorium on shale gas production is expected to be lifted. And plans to streamline and speed the regulatory process through a new Office for Unconventional Gas and Oil were unveiled last week in the annual autumn budget statement by the chancellor of the exchequer, George Osborne.

In the U.K., where all underground mineral rights concerning fossil fuels belong to the crown, hydraulic fracturing, or fracking, could unlock a new stream of government revenue as well as fuel. But it also means that there is no natural constituency of fracking supporters as there is in the United States, birthplace of the technology. In the U.S., concerns over land and water impact have held back fracking in some places, like New York, but production has advanced rapidly in shale basins from Texas to Pennsylvania, with support of private landowners who earn royalties from leasing to gas companies.

A taste of the fight ahead in the U.K. came ahead of Osborne's speech last weekend, when several hundred protesters gathered outside of Parliament with a mock 23-foot (7-meter) drilling rig. In a letter they delivered to Prime Minister David Cameron, they called fracking "an unpredictable, unregulatable process" that was potentially toxic to the environment.

Giving shale gas a green light "would be a costly mistake," said Andy Atkins, executive director of the U.K.'s Friends of the Earth, in a statement. "People up and down the U.K. will be rightly alarmed about being guinea pigs in Osborne's fracking experiment. It's unnecessary, unwanted and unsafe."

The government has countered that natural gas-fired power plants would produce half the carbon dioxide emissions of the coal plants that still provide about 30 percent of the U.K.'s electricity. London Mayor Boris Johnson, viewed as a potential future prime minister, weighed in Monday with a blistering cry for Britain to "get fracking" to boost cleaner, cheaper energy and jobs. "In their mad denunciations of fracking, the Greens and the eco-warriors betray the mindset of people who cannot bear a piece of unadulterated good news," he wrote in the Daily Telegraph.

Energy Secretary Edward Davey, who is expected this week to lift the U.K.'s year-and-a-half-old moratorium on shale gas exploration, said gas "will ensure we can keep the lights on as increasing amounts of wind and nuclear come online through the 2020s."

A Big Role for Gas

If the fracking plan advances, it will not be the first "dash for gas" in the U.K. In the 1980s, while Prime Minister Margaret Thatcher battled with mining unions, she undercut their clout by moving the nation toward generating a greater share of its electricity from natural gas and less from coal. So natural gas already is the largest electricity fuel in Britain, providing 40 percent of electricity. (Related Interactive: "World Electricity Mix")

The United Kingdom gets about 10 percent of its electricity from renewable energy, and has plans to expand its role. But Davey has stressed the usefulness of gas-fired plants long-term as a flexible backup source to the intermittent electricity generated from wind and solar power. Johnson, on the other hand, offered an acerbic critique of renewables, including the "satanic white mills" he said were popping up on Britain's landscape. "Wave power, solar power, biomass—their collective oomph wouldn't pull the skin off a rice pudding," he wrote.

As recently as 2000, Great Britain was self-sufficient in natural gas because of conventional gas production in the North Sea. But that source is quickly drying up. North Sea production peaked in 2000 at 1,260 terawatt-hours (TWH); last year it totaled just 526 TWh.

Because of the North Sea, the U.K. is still one of the world's top 20 producers of gas, accounting for 1.5 percent of total global production. But Britain has been a net importer of gas since 2004. Last year, gas imports—mainly from Norway, Belgium, and the Netherlands—accounted for more than 40 percent of domestic demand.

The government hopes to revive domestic natural gas production with the technology that has transformed the energy picture in the United States—horizontal drilling into deep underground shale, and high-pressure injection of water, sand, and chemicals to create fissures in the rock to release the gas.

A Tougher Road

But for a number of reasons, the political landscape is far different in the United Kingdom. Britain made a foray into shale gas early last year, with a will drilled near Blackpool in northwest England. The operator, Cuadrilla, said that that area alone could contain 200 trillion cubic feet of gas, which is more than the known reserves of Iraq. But the project was halted after drilling, by the company's own admission, caused two small earthquakes. (Related: "Tracing Links Between Fracking and Earthquakes" and "Report Links Energy Activities To Higher Quake Risk") The April 2011 incident triggered the moratorium that government now appears to be ready to lift. Cuadrilla has argued that modifications to its procedures would mitigate the seismic risk, including lower injection rates and lesser fluid and sand volumes. The company said it will abandon the U.K. unless the moratorium is soon lifted.

A few days ahead of Osborne's speech, the Independent newspaper reported that maps created for Britain's Department of Energy and Climate Change (DECC) showed that 32,000 square miles, or 64 percent of the U.K. countryside, could hold shale gas reserves and thus be open for exploration. But a DECC spokeswoman said "things are not quite what it [the Independent story] suggests." Theoretically, she said, those gas deposits do exist, but "it is too soon to predict the scale of exploration here." She said many other issues, ranging from local planning permission to environmental impact, would mean that some tracts would be off limits, no matter how much reserve they held. DECC has commissioned the British Geological Survey to map the extent of Britain's reserves.

Professor Paul Stevens, a fellow of the Royal Institute of International Affairs, said the U.K. is clearly interested in trying to replicate America's shale gas revolution. "That's an important part of the story," he said, but trying to use the American playbook won't be easy. "It's a totally different ballgame." In addition to the fact that mineral rights belong to the crown, large expanses of private land that are commonplace in America don't exist in England. Just as important, there is no oil- and gas-service industry in place in Britain to quickly begin shale gas operations here. "We don't have the infrastructure set up," said Richard Davies, director of the Durham Energy Institute at Durham University, adding that it would take years to build it.

Shale gas production would also likely ignite bigger and louder protests in the U.K. and Europe. "It's much more of a big deal in Europe," Stevens said. "There are more green [nongovernmental organizations] opposed to it, and a lot more local opposition."

In any case, the U.K. government plans to move ahead. Osborne said he'll soon begin consultations on possible tax breaks for the shale gas industry. He also announced that Britain would build up to 30 new natural gas-fired power plants with 26 gigawatts (GW) of capacity. The new gas plants would largely replace decommissioned coal and nuclear power plants, though they would ultimately add 5GW of additional power to the U.K. grid. The coalition government's plan, however, leaves open the possibility of increasing the amount of gas-generated electricity to 37GW, or around half of total U.K. demand.

The U.S. Energy Information Administration (EIA) estimates that Europe may have as much as 600 trillion cubic feet of shale gas that could be recovered. But Stevens said no European country is ready to emulate the United States in producing massive amounts of unconventional gas. They all lack the necessary service industry, he said, and geological differences will require different technologies. And governments aren't funding the research and development needed to develop them.

Globally, the track record for efforts to produce shale gas is mixed:

• In France, the EIA's estimate is that shale gas reserves total 5 trillion cubic meters, or enough to fuel the country for 90 years. But in September, President Francois Hollande pledged to continue a ban on fracking imposed last year by his predecessor, Nicolas Sarkozy.
• Poland was also thought to have rich shale gas resources, but initial explorations have determined that original estimates of the country's reserves were overstated by 80 percent to 90 percent. After drilling two exploratory wells there, Exxon Mobil stopped operations. But because of its dependence on Russian gas, Poland is still keen to begin shale gas production.
• South Africa removed a ban on fracking earlier this year. Developers are eyeing large shale gas reserves believed to underlie the semidesert Karoo between Johannesburg and Cape Town.
• Canada's Quebec Province has had a moratorium on shale gas exploration and production, but a U.S. drilling company last month filed a notice of intent to sue to overturn the ban as a violation of the North American Free Trade Agreement.
• Germany's Environment Ministry has backed a call to ban fracking near drinking water reservoirs.
• China drilled its initial shale gas wells this year; by 2020, the nation's goal is for shale gas to provide 6 percent of its massive energy needs. The U.S. government's preliminary assessment is that China has the world's largest "technically recoverable" shale resources, about 50 percent larger than stores in the United States.

Closing Tax Loopholes Not Enough to Avert 'Cliff'?

Closing "corporate tax loopholes" sure sounds good to the average, non-corporate American -- so good, in fact, that politicians talk about it all the time.

House Speaker John Boehner's fiscal-cliff proposal purports to raise $1.6 trillion in revenue by "clos[ing] special-interest loopholes and deductions while lowering rates."

The White House, meanwhile, has complained that Boehner hasn't offered specific loopholes to cut.

On the other side of the aisle, House Democrats have repeatedly offered up "closing overseas tax loopholes" as a means to pay for spending bills -- a plan Republicans routinely reject. In the last two and a half years, President Obama has often been heard griping about writeoffs for corporate jets.

For both Republicans and Democrats, "corporate tax loopholes" are an old saw. But, like most things in politics, raising revenue from "loopholes" gets a bit stickier when the specifics are hashed out.

A misconception about tax "loopholes," some experts say, is that they're loopholes -- gaps in the tax law that corporations have exploited against the law's intent.

Fiscal Cliff Battle: President Obama vs. Speaker John Boehner Watch Video

"Most of these proposals were not 'loopholes,' these were incentives," said Eric Toder, co-director of the left-leaning Tax Policy Center.

For example, take the research-and-development tax credit. During the campaign, both Obama and Mitt Romney suggested making it permanent.

"One wouldn't call the research credit a loophole," Toder said.

Cashing in by closing the biggest "loopholes" could be a politically fraught endeavor. To generate meaningful revenue, House Republicans would have to sign off on measures that raised it from taxing the overseas profits of multinational corporations, from ending immediate writeoffs of equipment purchases, or from ending a credit for domestic manufacturing.

When the Joint Committee on Taxation scored some of these provisions, as part of a tax-reform bill pushed by Democratic Sen. Ron Wyden and then-GOP-senator Judd Gregg, it found the government could save significantly:

Savings Over 10 Years: 2011-2021

Taxing Overseas Profits of Multinational Corps: $582.7 billion. In other words, the "overseas tax loophole" Democrats are fond of trashing. While most countries with large economies tax only profits made at home, the U.S. code taxes all income everywhere. To offset the different, U.S. multinational corporations receive credits to prevent double taxing. They also can defer paying any tax on foreign income, until they transfer the money back to the United States.

Taxing that profit could generate significant revenue. But this could be controversial, and large corporations would fight it. A senior aide to one business lobbying group said ending foreign-income deferral would amount to double-taxing U.S. companies and put them at a disadvantage to foreign competitors; one supporter of ending deferral suggested U.S. companies have been able to hide profits overseas, avoiding taxes altogether.
