Some children may lose autism diagnosis with age

Some children diagnosed with autism in early childhood may no longer have the disorder as they grow older, according to research funded by the National Institutes of Health.

"Although the diagnosis of autism is not usually lost over time, the findings suggest that there is a very wide range of possible outcomes," said Dr. Thomas R. Insel, NIMH director, said in a press release. "For an individual child, the outcome may be knowable only with time and after some years of intervention."

Autism spectrum disorders are a group of developmental disorders that cause behavioral, social and communication problems. The Centers for Disease Control and Prevention estimate one in 88 children have an ASD.

Headlines: Report says kids can grow out of autism

The new study looked at 34 children between 8 and 21 who had an "optimal outcome," meaning they were diagnosed with autism earlier in life but functioned normally compared to their peers later on. These subjects were matched by age, sex, and nonverbal IQ with 44 children with high-functioning autism and an additional 34 typically developing peers.

The researchers reviewed their initial diagnoses to make sure they were accurate and enlisted a second diagnostic expert, who didn't know the child's status, to review reports where the initial diagnosis had been removed.

What they discovered was the "optimal outcome" children had milder social problems than those in the high-functioning autism group in early childhood. Verbal IQ of "optimal outcome" children were slightly higher than high-functioning autism individuals. However when it came to communication and behavioral problems, there were similarities to the high-functioning subjects.

The researchers then examined all the subjects using standard cognitive tests and parent questionnaires. The "optimal outcome" children were all in regular education classes with no special education aimed at autism. The whole group showed no signs of problems with language, face recognition, communication, and social interaction.

Researchers cannot speculate which percentage of children will outgrow their ASD, but they are hoping that through the research they gathered they can see whether the diagnosis changed because brain function normalized or the brain was able to make up for autism-related deficiencies.

Is it autism? Facial features that show disorder

"All children with ASD are capable of making progress with intensive therapy, but with our current state of knowledge most do not achieve the kind of optimal outcome that we are studying," study author Deborah Fein, a professor at the Department of Psychology at University of Connecticut, said in a press release. "Our hope is that further research will help us better understand the mechanisms of change so that each child can have the best possible life."

The study published Jan. 16 in the Journal of Child Psychology and Psychiatry.

Researchers are also looking at which therapies led to the most success. Fein told HealthDay she believed behavioral treatments were the most likely to result in an "optimal outcome." However, even for children that lose the diagnosis, she said that parents should not stop therapy "prematurely" since these children are still at risk for attention problems and anxiety.

"But I want to point out that this is the result of years of hard work," she added. "This is not anything that happens overnight. I would say that at minimum we're talking about two to three years of intensive therapy to produce this outcome, but it could also be five years. It's variable.

"This is the first solid science to address this question of possible recovery, and I think it has big implications," added Dr. Sally Ozonoff of the MIND Institute at the University of California, Davis, who was not involved in the study, to the New York Times. "I know many of us as would rather have had our tooth pulled than use the word 'recover,' it was so unscientific. Now we can use it, though I think we need to stress that it's rare."

But, other experts warned that parents shouldn't get their hopes up that their child will outgrow their diagnosis.

"This study is looking at a small sample of high functioning people with autism and we would urge people not to jump to conclusions about the nature and complexity of autism, as well its longevity," Dr. Judith Gould, director of the National Autistic Society's Lorna Wing Centre for Autism, told the BBC. "With intensive therapy and support, it's possible for a small sub-group of high functioning individuals with autism to learn coping behaviors and strategies which would 'mask' their underlying condition and change their scoring in the diagnostic tests used to determine their condition in this research."

'Catfish' Star Reaches Out to Manti Te'o

Nev Schulman, the star and creator of the MTV show "Catfish" that follows Internet dating hoaxes, has reached out to Notre Dame football star Manti Te'o and offered to help solve his girlfriend hoax.

Te'o and Notre Dame claim he was a "catfish" victim when it was revealed that the woman he said was his girlfriend and died of leukemia never existed.

The "Catfish" television show was spawned by a movie of the same name in which Schulman tracked down a person who pretended to be a young woman he had met online.

".@MTeo_5 I know how you feel. It happened 2 me. I want 2 help tell ur story & prevent this from happening to others in the future. Lets talk," Schulman tweeted to Te'o.

Schulman says in his tweets that he has information about the baffling hoax. "I am working on finding out more about this @MTeo_5 #Catfish story. I have been in contact with the woman involved and will get the truth," Schulman tweeted on Wednesday night. It is unclear which woman Schulman has been in contact with.

However, in a statment released to ABC News, Schulman said "I have been in touch with Donna Tei. She reached out to me back in December asking for help regarding the person who had been using her photos to create a fake profile."

It's not clear whether Donna Tei was the woman whose photo was used as "girlfriend" Lennay Kekua or another person in the complicated hoax.

He also tweeted, "However his #Manti story ends, it doesn't change that we are all the victims of a #Catfish."

In a statement on MTV.com, Schulman defended the possibility that Te'o had been duped.

"When you read an article all at once where it reveals all these stories and all these details, it seems crazy, but in the process of it, as it happens very slowly, things don't seem so crazy," Schulman wrote. "And then, of course, when you look at it all in one snapshot, it does sort of seem kind of unbelievable."

Notre Dame Athletic Director Jack Swarbrick cited the documentary "Catfish" in trying to explain how the star linebacker became a hoax victim.

"I would refer all of you, if you're not already familiar with it, with both the documentary called 'Catfish,' the MTV show which is a derivative of that documentary, and the sort of associated things you'll find online and otherwise about catfish, or catfishing," Swarbrick told reporters Wednesday.

The 2010 film stars Schulman, who was the real-life victim of a "catfish" scam. Schulman wanted to make the documentary to show how he was sucked in by an Internet pretender -- or a "catfish" -- who built an elaborate fake life.

Schulman made the documentary as he was falling for someone named "Megan," a gorgeous 20-something from Michigan. Their online relationship blossomed until Schulman confronted "Megan."

"Megan" turned out to be a middle-aged mom of two named Angela Wesselman, who later said she had been diagnosed with schizophrenia.

"It was different. It was something new. It was a little mysterious," Schulman told ABC News in an earlier interview, describing his reaction before he discovered Megan's true identity.

Now, a much wiser Schulman is helping others catch the "catfish" in his new hit series on MTV inspired by the real-life documentary, "Catfish: The TV Show."

'Catfish' Stars Nev Schulman's Advice for Online Dating

In one episode, Schulman meets Sunny, who says she has been dating a medical student online named "Jameson" for eight months.

"He's going to be an anesthesiologist. He does online classes," Sunny says of "Jameson" in the episode.

Schulman convinces Sunny to take a road trip to meet "Jameson" face to face and and Sunny later finds out "Jameson" was really a woman who was pretending to be a man online for at least four years.

"I mean who does that?" Sunny said in the episode.

As more become connected through various social media outlets, Schulman says these "catfish" hoaxes will continue.

"So long as we're not looking people in the eye face-to-face, there's always going be room, a lot of room for deception," he said.

Gruesome toll of cluster bombs in Syria

STORY HIGHLIGHTS

• Human Rights Watch says cluster bombs were used on Syrian town of Latamneh


• Cluster bombs release dozens of smaller bombs, which can maim or kill long after impact


• Syrian regime has previously denied cluster bombs on civilians

Editor's note: Mary Wareham is the Arms Division's Advocacy Director for Human Rights Watch and chief editor of 'Cluster Munition Monitor 2012.'

(CNN) -- It was cloudy the afternoon of January 3 when residents say the cluster bombs fell on the Syrian town of Latamneh.

Three rockets containing the cluster munitions fell in nearby fields, apparently doing no harm, but a fourth landed on the street between residential buildings. Its impact was devastating.

One man was driving down the street when submunitions from the rockets exploded, killing him instantly, residents said. Fifteen civilians walking down the street or in their homes were wounded, including women and children, according to two residents and video evidence. Residents said that an hour after the attack, a submunition that had failed to detonate on impact killed a man who tried to remove it from his yard. It exploded in his hands.

Mary Wareham

Since mid-2012, Human Rights Watch and others have reported several times on civilian casualties caused by Syrian use of air-dropped cluster bombs, but Latamneh and other recent attacks are the first known instances of Syrian use of ground-based cluster munitions. The rockets were apparently launched from the vicinity of nearby Hama airport, which is under government control.

Evidence we have seen suggests that Syrian government forces delivered the 122mm cluster munition rockets containing submunitions using a BM-21 Grad multi-barrel rocket launcher, a truck-mounted system capable of firing 40 rockets nearly simultaneously with a range of 4 to 40 kilometers (2.5 to 25 miles). Grad rocket launchers are notorious for their inability to be accurately targeted due to their lack of a guidance system. This exacerbates the danger from the wide-area effect of the submunitions the rockets contain.

More: Syrian regime denies use of cluster bombs

Many countries, including Lebanon and Cambodia, have experienced civilian casualties from similar types of submunitions, both at the time of attack and from submunitions that didn't explode on initial impact. Each submunition is the size of a D-cell battery with a distinctive white ribbon, and the design of their fuze system makes each one very sensitive and liable to detonate if disturbed.

After years of civilian harm caused by cluster munitions, Israel's massive use of the weapons in southern Lebanon in 2006 helped propel governments into action. Working with civil society groups such as Human Rights Watch and international organizations, a broad-based coalition of like-minded governments sought to do something to reduce the unacceptable harm caused by cluster munitions.

The resulting Convention on Cluster Munitions, adopted May 30, 2008, comprehensively prohibits cluster munitions and requires their clearance and assistance to victims. A total of 111 nations, including many former users, producers, and stockpilers of the weapon, as well as countries contaminated by cluster munition remnants, have embraced the ban convention.

Yet there has been limited interest in the Middle East and North Africa regions, where just three countries—Iraq, Lebanon, and Tunisia—are onboard the treaty banning cluster bombs. Some nations, such as Jordan, say they need more time to study the convention's provisions, while others including Egypt, Iran, and Israel have produced, imported, exported, and stockpiled cluster munitions.

The 122mm cluster munition rockets used by Syria bear the markings of the Egyptian state-owned Arab Organization for Industrialization and an Egyptian company called Sakr Factory for Development Industries. Syria could have bought these cluster munitions from Egypt, received them through military cooperation, or acquired them another way. With no transparency, it is impossible to say how or when they were made or transferred, though it is likely Syria acquired them long ago.

Syria's relentless use of cluster munitions, including in populated areas, is yet another sign of its blatant disregard for international law and the protection of its own civilians. Syria's use of cluster munitions runs counter to the new international standard being created by the Convention on Cluster Munitions, rejecting any use of the weapons.

The preventive impact of the convention and the standard it is establishing can already be seen as countries that have joined the ban rapidly destroy their stockpiles of cluster munitions.

In Syria, every time the government has used cluster munitions and other explosive weapons, a lethal legacy of unexploded ordnance is created. Given the terrible humanitarian impact, all governments, regardless of their position on joining the ban convention, should press Syria to stop using cluster munitions.

Syria blasts kill 22 as students mourn campus dead

DAMASCUS: Twin car bombs killed at least 22 people in the Syrian city of Idlib on Wednesday as universities nationwide held a day of mourning for 87 people killed in explosions on the student campus in second city Aleppo.

The bombings had the hallmarks of operations staged by the jihadist Al-Nusra Front, a rebel group with a strong presence on the ground in northwestern Syria and blacklisted by the United States as a "terrorist" organisation.

"The first explosion took place in Al-Ziraa Square and the second explosion took place in Al-Mutlaq Square, killing 22 civilians and wounding 30," the state SANA news agency reported, blaming "terrorists" for the blasts.

Idlib city remains under the control of forces loyal to President Bashar al-Assad but most of the rest of the northwestern province on the border with Turkey is in the hands of rebels fighting to oust him.

The Syrian Observatory for Human Rights gave a higher toll of 24 dead and said most were soldiers. The Britain-based watchdog said there were three bombs in all and that many of the wounded were in critical condition.

"After taking the airbase at Taftanaz (on January 11), the city of Idlib has become the rebels' new target," Observatory directory Rami Abdel Rahman told AFP.

The Observatory said the death toll from Tuesday's blasts at Aleppo University could top 100 as many of the wounded were critically hurt, which would make it one of the bloodiest attacks of the 22-month conflict.

Washington on Wednesday condemned the "despicable attack," blaming regime air attacks.

"According to eyewitnesses at the scene, regime planes launched aerial strikes on university facilities," State Department spokeswoman Victoria Nuland told journalists.

No one has claimed responsibility for the explosions, with the government and rebels blaming each other.

Opposition activists said government jets carried out an air strike, but the army said rebels fired rockets at the campus, in a government-controlled area of the battleground northern city.

"The General Command of the Army sees in the targeting of academics, colleges and universities further proof of the killers' dark methods, and of an ideology that belongs in the past," a military statement said.

Higher Education Minister Mohammed Yahia Moalla called a nationwide "day of mourning" on Wednesday, state television reported.

In a letter addressed to UN Secretary General Bank Ki-moon and the UN Security Council, the foreign ministry called on the international community to "denounce the terrorist massacre."

Alluding to Western support for France's military intervention against Islamist rebels in Mali, the ministry said "some countries in the world are practising two-faced politics, by supporting terrorism in Syria and denouncing it in others."

Ban sent his condolences on Wednesday to the families of those killed and said "deliberate targeting of civilians and civilian targets constitutes a war crime."

He stressed the "urgent need for a peaceful political solution that ends the violence and meets the democratic aspirations of the Syrian people."

Near the capital, the army sent reinforcements to the town of Daraya as warplanes and rockets bombarded the rebel enclave, the Observatory said.

"The army's assault is insanely violent. The shelling is continuous; it has been so intense in the past hours. There are many injured people," said local activist Abu Kinan.

More than 60,000 people have been killed in Syria since the uprising against Assad's rule erupted in March 2011, according to the United Nations.

The Observatory said 103 people died in violence nationwide on Wednesday, including 44 civilians.

Meanwhile, the World Food Programme said that it would quickly try to distribute aid to an additional one million Syrians after Damascus gave the green light for it to work with local aid organisations to reach more of those in need.

Previously most of the UN agency's food aid was delivered through the Syrian Arab Red Crescent, which was overstretched and only able to provide help to some 1.5 million Syrians a month.

Opinion: Real hypocrites are at NRA

The National Rifle Association has released a video game, "Practice Range," a month after the Newtown, Connecticut, massacre.

STORY HIGHLIGHTS

• NRA releases shooting video game rated for ages 4 and up for free download


• Christopher Ferguson: NRA condemned video game industry less than a month ago


• Ferguson says the NRA doesn't even take its own claims seriously


• As queasy as the app is, video games do not cause more violence, he says

Editor's note: Christopher J. Ferguson is chair of the psychology and communication department at Texas A&M International University. He is the author of the novel "Suicide Kings."

(CNN) -- The nation has struggled with addressing how best to reduce gun violence following last month's tragic shooting in Newtown, Connecticut. Responding to calls for gun control, the National Rifle Association attempted to shift blame for mass homicides away from guns to cultural influences such as video games or entertainment. No one can accuse the NRA of not being clever. At least not until it released a gun-themed shooting game less than a month after condemning the video game industry.

In fairness, "Practice Range," rated for ages 4 and up and free on the iPhone and iPad, is no blood-soaked, first-person shooter game. The trailer shows that it allows the player to engage in target practice using realistic-looking weapons. One of the weapon options appears to be an AR-15, the same weapon used at Newtown. The game also includes some gun safety tips.

Christopher J. Ferguson

I have no objection to the game per se, although the NRA's app smacks of hypocrisy.

Releasing a gun-themed shooting video game a month after the Newtown massacre reveals that the NRA doesn't even take its own claims seriously. As for the NRA's assertion that games create violence, it is nakedly self-serving.

But, as queasy as the whole thing is, violent video games do not cause more violence. Several researchers, including myself, met with Vice President Joe Biden on Friday to inform him that studies are unable to support the contention that violent video games contribute to societal violence. Rather, it is untreated mental health symptoms that contribute to outcomes including youth violence, dating violence and bullying.

As Fareed Zakaria aptly noted, nations that consume more video games per capita than the United States such as Japan, or share our media culture almost identically such as Canada, have much lower violence rates than our country.

That's true even if you exclude gun violence and consider only simply assaults. And mass homicide perpetrators are no more likely to be gamers than the rest of us. Our society experiences confirmation bias, focusing on video games when the shooter is a young male, and ignoring video games when the shooter is an older male such as 62-year-old William Spengler, who shot two firefighters the week after the Sandy Hook Elementary School shooting. This confirmation bias creates the false impression of a correlation where none exists.

The NRA is apparently unaware that most theories of media effects make little distinction between a game such as "Practice Range" and one such as "Grand Theft Auto." According to such theories, seeing a picture of a gun or reading "Grimm's Fairy Tales" is as likely to stimulate aggression as a blood-soaked movie or game.

Granted, the U.S. Supreme Court didn't buy that argument in 2011 when it considered a California law regulating the sale of violent games to minors, and criticized the quality of the research attempting to link violent games with aggression more broadly.

I don't believe either "Practice Range" or "Grand Theft Auto" harms minors, although of course some games may have morally objectionable content. But the NRA can't claim, "Video games create mass killers. Oh wait, hey, not this one!"

There are reasonable things we could do to reduce gun violence while respecting the rights of law-abiding citizens to own guns. For example, better and more consistent background checks and required reporting by mental health professionals when patients make violent threats (requiring the removal of firearm licenses from those individuals) would go a long way. We can also put out public health campaigns to warn people of the risks of gun ownership so they could make informed decisions of their own without their constitutional rights being violated.

Sensible changes will not occur if the nation indulges in a moral panic about violent video games as it did after the Columbine massacre. This, undoubtedly, would be exactly what the NRA would like to see happen.

13 home buying tips for 2013

(MoneyWatch) Although housing prices started to rebound last year and are expected to continue rising in 2013, it's still a buyer's market. Prices remain 30 percent below their peak before the housing crash and mortgage rates hovering at all-time lows. If you are ready to jump in to the real estate market, here are 13 house-hunting tips for 2013.

1. Run the numbers. Put together a financial plan to determine whether you can really afford to buy. After all, just because it's a good time to purchase a home doesn't mean it's a good time for YOU to buy. It's important to understand how much home you can afford and whether home ownership might preclude you from addressing other important financial issues in your life.

2. Save 20 percent for a down payment. I'm not a huge fan of putting down less than that amount (although the Federal Housing Administration allows it). Keep your downpayment fund in cash or cash equivalent accounts, so that market movements don't thwart your plans.

3. Use this great "rent vs. buy" calculator from the New York Times. Renting might still be the better deal in your area.

4. Be an informed buyer. You're not going to buy a house simply because there's a pretty photo posted online, but you can conduct a lot of price research. That said, there's nothing better than talking to people in the neighborhood for "on the ground" intelligence.

5. Obtain a copy of your credit report. If you haven't done so in a while, go to AnnualCreditReport.com and request your free copy. It's important that you correct any errors on the report before you start the mortgage process.

6. Get pre-approved for a mortgage. Pre-approval is a good gut check on your price range for a home. Gone are the days that banks will fork over cash to anyone with a heartbeat. The best way to start is to ask friends for referrals from mortgage brokers and to shop around with banks and credit unions. Make sure to compare apples to apples and to ask the broker about your total costs to you at closing. You should also know that once you actually find a home, the mortgage process is on the same pain level as a root canal, only it requires more patience and there's no Novocain. You'll need to dig up tons of paperwork and fair warning -- there will be multiple requests for even more documents as you move toward closing. Eventually, you will need "commitment letter," which details the terms of your loan approval.

7. Find an agent. As much as everyone complains about realtors, I still think that it's tough to go through the home buying process alone. In some markets, buyers' brokers are available, but the most important qualities in brokers are honesty, experience, good connections with other agents, and good referrals from buyers like you. Remember that most agents represent the seller, not the buyer.

8. Hire a real estate attorney. This is a major transaction in your life, so don't try to save money when it comes to legal fees. Even if your mortgage company provides a lawyer, hire your own to help draft all documents and to ensure that your interests are being represented at every step of the process.

9. Get an appraisal. An appraisal will determine the market value of the property and ultimately will be used by your lender to determine the amount of your loan. You have a legal right to get a copy of this and will want a copy for your records.

10. Schedule a home inspection. Think you've found your dream house? Maybe, but unless you have an engineer walk through the premises with you, you might be buying a new roof in a couple of years. Don't get freaked out if a problem arises during the inspection; it can often be addressed with a simple adjustment in price. It's imperative to protect yourself, so don't blow off this important step.

11. Start with a fair offer. The offer should be based on similar houses sold in the neighborhood in the past six months. Your agent will help you with the process, but the offer should include the price you're willing to pay for the house, your financing terms and contingencies such as specifying what will happen if any problems come up during the inspection.

12. Purchase homeowners insurance. If you are a life-long renter, this can be an eye-opener in terms of cost. Make sure that you understand the difference between insuring the structure and insuring the contents. And if you are buying property that is close to water, make sure that you have an agent who can help you enroll in the national flood insurance program.

13. Review your HUD statement BEFORE closing. The government document provides basic details about the involved parties and a lot of numbers. Mistakes do occur, which is why it is vital that you review the statement and confirm that everything is correct.

Obama Unveils Sweeping Plan to Curb Gun Violence

Flanked by four children from across the country, President Obama today unveiled a sweeping plan to curb gun violence in America through an extensive package of legislation and executive actions not seen since the 1960s.

Obama is asking Congress to implement mandatory background checks for all gun purchases, including private sales; reinstate a ban on some assault-style weapons; ban high-capacity magazines holding more than 10 rounds; and crackdown on illicit weapons trafficking.

The president's proposal also includes new initiatives for school safety, including a call for more federal aid to states for hiring so-called school resource officers (police), counselors and psychologists, and improved access to mental health care.

Obama also initiated 23 executive actions on gun violence, policy directives not needing congressional approval. Among them is a directive to federal agencies to beef up the national criminal background-check system and a memorandum lifting a freeze on gun violence research at the Centers for Disease Control and Prevention.

"I intend to use whatever weight this office holds to make them a reality," Obama said at a midday news conference. "If there's even one thing that we can do to reduce this violence, if there's even one life that can be saved, then we have an obligation to try.

"And I'm going to do my part."

The announcement comes one month after a mass shooting at Sandy Hook Elementary School in Newtown, Conn., left 26 dead, including 20 children. Obama called it the worst moment of his presidency and promised "meaningful action" in response.

Andrew Cuomo Signs New York Gun Control Law, Obama Readies Federal Plan Watch Video

'The View' on NRA Shooting App: Think It Out Watch Video

The proposals were the work of an Obama-appointed task force, led by Vice President Joe Biden, that held 22 meetings on gun violence in the past three weeks. The group received input from more than 220 organizations and dozens of elected officials, a senior administration official said.

As part of the push, Obama nominated a new director for the Bureau of Alcohol, Tobacco and Firearms, which leads enforcement of federal gun laws and has been without a confirmed director for six years. The president appointed acting director Todd Jones, the U.S. attorney for Minnesota, to the post, if the Senate confirms him.

The administration's plan calls for aid to states for the hiring of more school resource officers, counselors and psychologists. Obama also directed the Department of Education to ensure all schools have improved emergency-response plans.

He also called on Congress to make it illegal to possess or transfer armor-piercing bullets; it's now only illegal to produce them.

"To make a real and lasting difference, Congress must act," Obama said. "And Congress must act soon."

Officials said some of the legislative measures Obama outlined could be introduced on Capitol Hill next week. The pricetag for Obama's entire package is $500 million, the White House said.

"House committees of jurisdiction will review these recommendations," a spokesman for House Speaker John Boehner said in response to Obama's announcement. "And if the Senate passes a bill, we will also take a look at that."

The proposals are already being met with stiff opposition from gun rights advocates, led by the National Rifle Association, which overnight released a scathing ad attacking the president as an "elitist hypocrite."

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

Obama has questioned the value of placing more armed guards at schools around the country, although his proposal does call for placement of more police officers at public schools. The NRA opposes most of the other gun restrictions Obama has proposed.

"Keeping our children and society safe remains our top priority," the NRA said in a statement after Obama's announcement.

"Attacking firearms and ignoring children is not a solution to the crisis we face as a nation," the group said. "Only honest, law-abiding gun owners will be affected and our children will remain vulnerable to the inevitability of more tragedy."

Are gun curbs just symbolism?

STORY HIGHLIGHTS

• Gun violence recommendations are expected from Vice President Biden on Tuesday


• The proposals are expected to contain substantive and symbolic ideas to curb gun violence


• Presidents use symbolism to shift public opinion or affect larger political or social change

Washington (CNN) -- The pictures told the story: Vice President Joe Biden looked solemn, patrician and in control as he sat at a long table in the White House, flanked by people on both sides of the gun control issue.

The images conveyed a sense that the White House was in command on this issue.

And that's the point. Historically, presidential administrations have used symbolic imagery—at times coupled with marginal actions—to shift public opinion or affect larger political or social change.

"Politics is a risk taking project," said Julian Zelizer, a Princeton University historian and CNN contributor. "They put together these commissions in response to some crisis. You try a hundred things and hope something works."

As Biden's gun control task force recommendations land on the desk of President Barack Obama, political experts say it is important that his administration sends a clear signal that it has things in hand.

Obama says gun lobby stokes fear of federal action

That is especially critical in what will likely be an uphill battle to push specific changes, like an assault weapons ban, as part of a broader effort on gun control.

The first move in the image battle will be to appear to move quickly and decisively.

"You have to give the Obama administration credit for one thing: They've learned from history to do things quickly," Larry Sabato, director of the University of Virginia's Center for Politics, said of previous task force initiatives that fizzled.

In 2010, Obama appointed a bipartisan commission headed by former Republican Sen. Alan Simpson of Wyoming and Erskine Bowles, a former Democratic White House chief of staff, to come up with a proposal to balance the budget and cut the debt.

Like the gun task force, Simpson-Bowles reviewed current regulations, gathered input from the public and engaged in tense internal conversations. But after months of working on a proposal—a blend of steep revenue increases and spending cuts—the group struggled to agree to a solution. The president did not take up the recommendations.

Obama largely avoided the issue of gun control during his first term.

He wrote an opinion piece two months after the 2011 assassination attempt on Rep. Gabrielle Giffords of Arizona, acknowledging the importance of the Second Amendment right to bear arms. In the piece he also called for a focus on "effective steps that will actually keep those irresponsible, law-breaking few from getting their hands on a gun in the first place."

Newtown searches for answers a month later

But in the aftermath of that shooting and as the election season loomed, the Justice Department backed off from a list of recommendations that included a measure designed to help keep mentally ill people from getting guns.

For now, at least, there is a sense in Washington that the Newtown, Connecticut, school shooting where 26 people -- 20 of them young children -- were slaughtered could lead to meaningful legislative reform.

Public opinion would seem to suggest that the White House efforts are well timed.

In the month since the massacre, a new poll showed the percentage of Americans who said they were dissatisfied with America's gun laws has spiked.

The Gallup survey released on Monday showed 38% of Americans were dissatisfied with current gun regulations, and wanted stricter laws. That represented 13-point jump from one year ago, when 25% expressed that view. "You want to strike while the iron is hot," Sabato said. "We Americans have short attention spans and, as horrible as the Newtown shooting was, will anyone be surprised if we moved along by spring?"

The White House has since worked overtime to show it considers gun control an urgent matter.

The vice president has spent the last week meeting with what the White House calls "stakeholders" in the gun control debate.

On Monday, Biden was to meet with members of a House Democratic task force on guns, along with Attorney General Eric Holder, Homeland Security Secretary Janet Napolitano, and Kathleen Sebelius, the secretary of Health and Human Services.

Universal background check: What does it mean?

In a series of face to face discussions on Thursday, Biden sat down with the National Rifle Association and other gun owners groups before conferring with representatives from the film and television industry.

In a sign the White House is prepared to move aggressively on its proposals, Biden made public comments just before meeting with the National Rifle Association, the country's most powerful gun lobby.

"Putting the vice president in charge of (the task force) and having him meeting with these groups is intended to show seriousness and an effort to reach out and respond to concerns and wishes of various groups," said Alan Abramowitz, a political science professor at Emory University.

Still, the NRA expressed disappointment in its discussion with Biden and later released a statement that accused the administration of mounting "an agenda to attack the Second Amendment."

Organizations seeking tougher gun control laws insist an assault weapons ban is critical to addressing the nation's recent rash of mass shootings. However, such a ban could be difficult in a Congress mired in gridlock.

"The bully pulpit is limited. It's hard for the president to sustain that momentum," Zelizer said of the White House's gun control efforts after the Newtown shootings. "The thing about symbolism is, like the shock over Newtown, they fade quickly."

Facebook launches search engine for friends' content

MENLO PARK: Facebook launched a search engine Tuesday for shared content as a way to find out more about friends on the huge social network in a potential challenge to Google and other Internet firms.

"We look at Facebook as a big social database," chief executive Mark Zuckerberg said in announcing the so-called "graph search" function. "Just like any database, you should be able to query it."

The search engine aims to help members better navigate the vast amount of information on Facebook, which is not available on Web search engines such as Google.

Facebook emphasised that the new effort is not Web search, but can help find certain information archived within the network and in the content of friends.

"Every piece of content on Facebook has its own audience, and most content isn't public," a Facebook statement said.

"We've built Graph Search from the start with privacy in mind, and it respects the privacy and audience of each piece of content on Facebook. It makes finding new things much easier, but you can only see what you could already view elsewhere on Facebook."

Zuckerberg said that Facebook will also use its partnership with Microsoft's Bing search engine for the new effort and to find content housed outside the social network.

"I don't necessarily think a lot of people will be coming to Facebook to do Web search because of this, but it is a very good search engine," he said.

He said Facebook had discussed working with Google but that "Microsoft was just more willing to do things that were specific to Facebook."

The social network offered examples of graph search queries including "friends who live in my city," "people from my hometown who like hiking," "friends of friends who have been to Yosemite National Park," "software engineers who live in San Francisco and like skiing," "people who like things I like," or "people who like tennis and live nearby."

Zuckerberg said the tool is aimed at "giving the people the power and tools to take any cut of the graph (of data) they want and make any query they want."

He added that "We are not indexing the Web here, we are indexing our map of the graph."

The company said the new function goes back to its original goals of helping people make connections.

"When Facebook first launched, the main way most people used the site was to browse around, learn about people and make new connections," the statement said.

"Graph Search takes us back to our roots and allows people to use the graph to make new connections."

Tech analyst Jeff Kagan said the new Facebook effort is a modest challenge to Google.

"If I were Google, I would see this as a Facebook warning shot across their bow. This is not an immediate attack, but nevertheless an attack is coming," Kagan said.

"Can Facebook transform the search engine world? If the answer is yes than this is a bigger threat to Google."

Forrester Research analyst Nate Elliott said Facebook's initiative aims to get people more engaged on the social network.

"Facebook's worst nightmare is a static social graph; if users aren't adding very many new friends or connections... their personal network becomes less and less active over time," Elliott said.

"But that may be happening: We haven't seen significant growth in the average number of friends per user recently. Graph search seems designed to encourage users to add more friends more quickly. If it means users' personal networks change more frequently, and become more active, then that keeps them coming back to the site -- which is vital to Facebook's success."

U.S. quietly giving up its oil addiction

President Obama at an oil and gas production field near Maljamar, New Mexico in March, 2012.

STORY HIGHLIGHTS

• Frida Ghitis: The U.S. will become the world's leading oil producer in a few years

• Despite energy independence, we need to keep looking into green energy, she says


• Ghitis: It's beneficial for the U.S. to not rely on unstable, undemocratic Middle East for oil

(CNN) -- We pay a lot of attention to revolutions when they emerge suddenly and violently, but when a transformation arrives gradually and peacefully it's easy to miss.

Let's stop for a moment and take a look at a slow-motion development changing the world as we know it: The United States is giving up its addiction to foreign oil.

For decades, we bemoaned the awful toll this addiction has taken. The need for oil and natural gas -- much of it from Middle Eastern dictatorships -- shaped the foundation of global geopolitics. It created morally questionable alliances and repeatedly placed Washington in a position to choose between its fundamental values and its economic interests. Now all that could change.

When President Obama started his first term, the country faced stiff economic headwinds. Now, as he prepares to start his second term, the country enjoys a rare and unexpected tailwind, propelling it in one of the most important areas, with a host of positive implications.

Frida Ghitis

Clearly, the booming American oil and gas businesses are not problem-free, but the benefits -- economic, geopolitical and environmental -- of this impending energy independence far outweigh the drawbacks.

The days when Mideast oil-producing dictatorships and their friends at OPEC could so easily wave their power over a trembling, oil-thirsty West are on their way to becoming a relic of the past.

America still needs imported oil. But growing production and shrinking consumption have created a most promising trend. According to the International Energy Agency, the United States will become the world's leading oil producer in just a few years. Imagine that. The United States could produce more oil than Saudi Arabia as early as 2017 and become a net oil exporter by 2030.

And if you count other petroleum products, the future is already here. In 2011, the United States exported more petroleum products -- including gasoline, diesel and other fuels -- than it imported. That had not happened in more than half a century.

David Frum: A tax we could learn to love

The first major sign of impact is visible in Iran. The loosening of oil markets has strengthened the world's hand against oil-rich Iran. One main reason the international community has been able to impose strong sanctions on Tehran, aimed at persuading the regime to stop its illegal nuclear enrichment program, is that the global economy can do without Iranian oil. Iran's production has fallen 40%, a drop that not long ago would have created unacceptable economic hardships for the rest of the planet.

The trend is even more dramatic when you include natural gas, a product that is revolutionizing energy markets. The United States is about to become the second-largest exporter of natural gas behind Russia. Gigantic oil and gas finds in the United States and elsewhere are transforming the landscape, in some cases quite literally.

Other than rising oil prices, the reason for this shift is that new and controversial technologies such as fracking and horizontal drilling have multiplied the amount of viable deposits in unexpected places. The techniques take an environmental toll, but there are upsides.

Fracking, as we keep learning, is creating very troubling problems, which deserve scrutiny. But it is helping to replace coal, the dirtiest form of energy production, with much cleaner natural gas.

Another dark lining in this silver cloud is that cheaper oil and gas will reduce incentives to produce green energies. Rather than abandoning the new sources of energy, efforts should focus on finding ways to reduce the negative impact of fracking and on continuing the push for alternative energy.

Fracking protesters say drilling jobs not worth environmental risks

The Obama administration now faces a balancing act as it starts its new term. Energy policy, the quest for full energy independence, must be weighed against the growing threat of climate change.

A decision on the controversial Keystone XL pipeline is imminent and political pressure against fracking will grow. The president should support strong climate legislation, without reversing the powerful gains of surging U.S. oil and gas production, with all its transformational benefits. The two goals are not mutually exclusive.

Once upon a time, America was the Saudi Arabia of whale oil, the fuel of its day. Whale oil was displaced by hydrocarbon production, which the United States also dominated. That started changing with enormous geopolitical consequences after easy, high quality oil was found in the Arabian Peninsula and other parts of the Middle East.

The United States built alliances with autocratic regimes as part of a commitment to satisfy its needs and preserve the free flow of oil, which became the life-blood of the global economy.

For oil-rich countries, this brought enormous fortunes, but it also brought something known as the "resource curse." With wealth concentrated in the hands of autocrats, corruption mushroomed, and other sectors of the economy withered.

A trend away from the concentration of oil production in such an unstable, undemocratic part of the world bodes well. It bodes well for human rights, and it also bodes well, ironically, for the economies of oil-rich countries, which may at long last find an incentive to diversify into other industries. It certainly bodes well for the U.S. economy, which is already creating tens of thousands of jobs in industries related to the new boom.

William Bennett: Damon's film overlooks fracking's boon

In what sounds like something from another era, the Energy Information Administration forecast declining gasoline prices for the next few years. That's the first bit of good news for American consumers. The really good news is the knowledge that soon, every time you fill up your tank you will not be sending a piece of your paycheck to the Middle East.

That, among other things, is excellent news for America's balance of trade and for the soundness of the U.S. economy, which sadly now struggles with a politically dysfunctional Washington.

No matter how much oil the United States and its friends in the Western Hemisphere produce, the Middle East remains a principal global petroleum producer for the foreseeable future. The United States still needs to ensure the free flow of oil, because a stop in production will cause prices to spike on global markets, affecting the entire planet.

But America and its friends are becoming much less vulnerable to oil shocks. And supplies from other parts of the world are becoming more plentiful. The emerging changes in the world's energy markets, if they continue to develop, are nothing short of revolutionary.

As Obama prepares for a new term in office, they are gradually rerouting us from a destiny that we had thought was inescapable and rather dismal to one that, while far from assured, looks much more promising.
