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.)

'We Can't Tolerate This Anymore,' Obama Says

President Barack Obama said at an interfaith prayer service in this mourning community this evening that the country is "left with some hard questions" if it is to curb a rising trend in gun violence, such as the shooting spree Friday at Newtown's Sandy Hook Elementary School.

After consoling victims' families in classrooms at Newtown High School, the president said he would do everything in his power to "engage" a dialogue with Americans, including law enforcement and mental health professionals, because "we can't tolerate this anymore. These tragedies must end. And to end them we must change."

Sandy Hook Elementary Shooting: Remembering the Victims Watch Video

The president was not specific about what he thought would be necessary and did not even use the word "gun" in his remarks, but his speech was widely perceived as prelude to a call for more regulations and restrictions on the availability of firearms.

The grieving small town hosted the memorial service this evening as the the nation pieces together the circumstances that led to a gunman taking 26 lives Friday at the community's Sandy Hook Elementary School, most first graders.

"Someone once described the joy and anxiety of parenthood as the equivalent of having your heart outside your body all of the time, walking around," he said, speaking of the joys and fears of raising children.

"So it comes as a shock at a certain point when you realize no matter how much you love these kids you can't do it by yourself," he continued. "That this job of protecting kids and teaching them well is something we can only do together, with the help of friends and neighbors, with the help of a community, and the help of a nation."

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.

Pakistan police battle militants after deadly airport raid

PESHAWAR, Pakistan: Six people were killed on Sunday as police and troops battled militants armed with automatic weapons, grenades and mortars in northwest Pakistan's Peshawar, a day after a deadly Taliban raid on the city's airport.

Fierce firing broke out after police acting on an intelligence report stormed a building near the airport, where a suicide and rocket attack on Saturday killed five civilians and the five attackers, and wounded 50 other people.

The assault late Saturday, claimed by the Pakistani Taliban, sparked prolonged gunfire and forced authorities to close the airport, a commercial hub and Pakistan Air Force (PAF) base in Peshawar on the edge of the tribal belt.

It was the second Islamist militant attack in four months on a military air base in nuclear-armed Pakistan. In August 11 people were killed when heavily-armed insurgents wearing suicide vests stormed a facility in the northwestern town of Kamra.

Police backed by troops launched a raid early Sunday on a building under construction near the airport following reports that five militants who fled after the airport attack had taken refuge there, according to provincial information minister Mian Iftikhar Hussain.

In the fierce shootout that followed, three militants and a policemen were killed, police said, while two other officers were wounded.

The clashes ended after six hours when the two remaining militants detonated their suicide vests inside the building, another senior police officer, Imtiaz Altaf, told AFP.

"All five militants are dead now and the area has been cleared," Altaf said.

"All of them were wearing suicide jackets. Three were killed in a shoot out with police, while two others blew themselves up in the building under construction."

A PAF statement said five attackers were killed on Saturday and no damage was done to air force personnel or equipment.

Dr Umar Ayub, chief of Khyber Teaching Hospital near the airport, said five civilians had also been killed and some 50 wounded.

"The base is in total control and normal operations have resumed. The security alert was also raised on other PAF air bases as well," the air force added.

Peshawar airport is a joint military-civilian facility. Civil Aviation Authority spokesman Pervez George said the passenger side had reopened after an 18-hour closure and there was no damage to the terminals.

The air force said Saturday's attackers used two vehicles loaded with explosives, hand grenades, rocket-propelled grenades and automatic weapons. One vehicle was destroyed and the second badly damaged.

Security forces found three suicide jackets near one of the vehicles, it said.

"Security forces consisting of Pakistan Air Force and Army personnel who were on full alert, cordoned off the base and effectively repulsed the attack," the air force said.

Television pictures showed a vehicle with a smashed windscreen, another damaged car, bushes on fire and what appeared to be a large breach in a wall.

Five nearby houses were destroyed after rockets landed on them and several other houses developed cracks, while the bomb squad detonated five out of eight bombs found near the base after the attack.

Pakistani Taliban spokesman Ehsanullah Ehsan told AFP by telephone from an undisclosed location that the group would continue to target the airport.

"Our target was jet fighter plans and gunship helicopters and soon we will target them again," he said.

The armed forces have been waging a bloody campaign against the Taliban in the country's northwest in recent years and the militants frequently attack military targets.

Aside from the August attack on Kamra, in May 2011 it took 17 hours to quell an assault claimed by the Taliban on an air base in Karachi. The attack piled embarrassment on the armed forces just three weeks after US troops killed Al-Qaeda leader Osama bin Laden in Pakistan.

Pakistan says more than 35,000 people have been killed as a result of terrorism in the country since the 9/11 attacks on the United States. Its forces have for years been battling homegrown militants in the northwest.

Google will alter search to end FTC antitrust inquiry, says report

The Federal Trade Commission may bring its two-year antitrust investigation of Google to a close by allowing the company to make voluntary changes to its search business, according to a report.

The search giant is said to be readying an announcement about changes to its use of "snippets," bits of text culled from sites such as Yelp and TripAdvisor and displayed in search results, Politico reports, citing unnamed sources. Yelp and others had charged Google with using their content without permission.

Google will also makes tweaks that will allow for easier porting of search-ad campaigns from Google to rival search services, Politico's sources said.

Politico suggested on Tuesday that the FTC may leave the search-related case to the European Commission, which has mounted an investigation of its own. Reuters reported on Tuesday that some Google competitors, sensing a possible defeat, are taking the case to the Justice Department.

Google and the FTC also look to be close to a settlement in a case involving so-called frand -- or standard essential -- patents owned by Google.

Politico said the FTC declined to comment on today's report about the search tweaks, and it said Google would provide only the following statement: "We continue to work cooperatively with the Federal Trade Commission and are happy to answer any questions they may have."

School Safety Questioned After Conn. Shooting

Along with fire drills, schools have been conducting lockdown drills -- often known as active shooter drills -- since the Columbine massacre in 1999.

But safety officials do not agree yet on what teachers and students should do when a homicidal gunman invades their school.

At Sandy Hook Elementary School, teachers, staff and students had been drilled on how to handle such a situation.

"We practice it, and they knew what to do, and you just think about protecting the kids, and just doing the right thing," library clerk Mary Ann Jacob said.

She said had been drilled to send the kids in the library to a back closet between book shelves, a plan developed in advance.

"You have to have a certain amount of fire drills, and evacuation drills, and a certain amt of lockdown drills," she said. "Kids know the routine, and the teachers know the routine, and everyone has a spot in the room where they are supposed to go to."

School safety expert Ken Trump told ABC News that he thinks the Sandy Hook teachers did what they could to protect their students.

"It does sound as though the teachers did everything humanly possible, down to risking their lives, to protect the children in this Connecticut school," Trump said.

The school's principal and five other adults died in the Sandy Hook school shooting in Newtown, Conn.

"Teaching kids to lock down, securing your rooms, and, in some cases, teachers stepping forth to protect the children at the risk of their own lives, is something that we see occurring more and more over the years in school safety," Trump said.

He and others particularly praised the actions of first grade teacher Kaitlin Roig, who locked her classroom door and barricaded herself and her 14 students in a locked bathroom.

But former SWAT officer Greg Crane told ABC News that he thinks existing lockdown procedures aren't sufficient.

"What she [Roig] did was a fantastic move," said Crane, who founded a school safety program called ALICE, which stands for alert, lock down, inform, counter, evacuate.

"Was she taught that move? Did every teacher know to lock the door and also barricade it? If that's the case, why weren't other teachers taught that?" Crane asked.

Most schools tell teachers to lock their doors and sit quietly until helps arrives, Crane said.

Typical are the procedures, obtained by ABCNews.com, outlined by a New Jersey school district that calls their drills "Lock Down Yellow."

Instructions to the students include:

"Go to the room nearest your location in the hallway.

"No one will be able to leave room for any reason.

"Silence must be maintained (Use of cell phones are not permitted).

"Make sure you are marked present.

"Do not leave the classroom until directed by PA System, telephone or by an administrator."

But Crane founded ALICE because he believed there was something wrong with the lock down-only policies in most schools.

"We've taught a generation of Americans to be passive and static and wait for police," said Crane, whose wife was an elementary school principal in Texas at the time of the Columbine attack.

"We don't recommend just locking a door because locked doors have been defeated before," Crane said. "Try to make yourself as hard a target as possible."

ALICE argues students and teachers should not be passive and that they should improvise. He even suggests they throw things are their attacker.

Obama calls for solidarity after school massacre

WASHINGTON: President Barack Obama on Saturday called for Americans to "come together" to prevent tragedies like the school massacre that killed 20 young children and six adults, one of the worst mass shootings in US history.

"This weekend, Michelle and I are doing what I know every parent is doing -- holding our children as close as we can and reminding them how much we love them," said Obama, father of Sasha, 10, and Malia, 14.

"There are families in Connecticut who can't do that today. And they need all of us now," he added, in his weekly address.

Twenty-seven people, including the shooter, were killed on Friday morning at an elementary school in Connecticut. US media reported that a 28th victim, found at a residence in the town, was the shooter's mother.

"While nothing can take the place of a lost child or loved one, all of us can extend a hand to those in need -- to remind them that we are there for them; that we are praying for them; and that the love they felt for those they lost endures not just in their own memories, but also in their community, and their country," he continued.

"Every parent in America has a heart heavy with hurt," Obama said. On Friday, he fought tears in an emotional address about the tragic incident.

"We grieve for the families of those we lost. And we keep in our prayers the parents of those who survived. Because as blessed as they are to have their children home, they know that their child's innocence has been torn away far too early," the president said.

Obama said the tragedy was all too familiar, after similar deadly shootings at a shopping mall in Oregon, at a Sikh temple in Wisconsin, and at a movie theatre in Colorado earlier this year.

"Any of these neighbourhoods could be our own. So we have to come together and take meaningful action to prevent more tragedies like this. Regardless of the politics," the president said, echoing his message from the day before.

Obama did not give details, but some US politicians called for a serious look at gun control laws, a subject which Obama, re-elected on November 6, did not tackle strongly in his first term.

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.
