FAA Grounds Boeing 787 Dreamliners

The Federal Aviation Administration has ordered the grounding of Boeing 787 Dreamliner jets until their U.S. operator proves that batteries on the planes are safe.

United is the only U.S. carrier flying the Boeing 787s, which have been touted as the planes of the future. However, several operated by overseas airlines have run into recent trouble, the latest because of a feared battery fire on a 787 today in Japan.

The FAA's so-called emergency airworthiness directive is a blow to Boeing, from the same government agency that only days ago at a news conference touted the Dreamliner as "safe." Even Secretary of Transportation Ray LaHood went so far as to say he would have no issue flying on the plane.

Now, United will need to prove to the FAA that there is no battery fire risk on its six Dreamliners. An emergency airworthiness directive is one that requires an operator to fix or address any problem before flying again.

"Before further flight, operators of U.S.-registered Boeing 787 aircraft must demonstrate to the Federal Aviation Administration (FAA) that the batteries are safe and in compliance," the FAA said in a statement today. "The FAA will work with the manufacturer and carriers to develop a corrective action plan to allow the U.S. 787 fleet to resume operations as quickly and safely as possible."

United Airlines responded tonight with a statement: "United will immediately comply with the airworthiness directive and will work closely with the FAA and Boeing on the technical review as we work toward restoring 787 service. We will begin reaccommodating customers on alternate aircraft."

There are some 50 Dreamliners flying in the world, mostly for Japanese airlines, but also for Polish and Chilean carriers.

Overseas operators are not directly affected by the FAA's emergency airworthiness directive -- but Japanese authorities grounded all of their 787s overnight after All Nippon Airways (ANA) said a battery warning light and a burning smell were detected in the cockpit and the cabin, forcing a Dreamliner, on a domestic flight, to land at Takamatsu Airport in Japan.

The plane landed safely about 45 minutes after it took off and all 128 passengers and eight crew members had to evacuate using the emergency chutes. Two people sustained minor injuries on their way down the chute, Osamu Shinobe, ANA senior executive vice president, told a news conference in Tokyo.

ANA and its rival, Japan Airlines (JAL), subsequently grounded their Dreamliner fleets. ANA operates 17 Dreamliner planes, while JAL has seven in service.

Both airlines said the Dreamliner fleet would remain grounded at least through Thursday.

ANA said the battery in question during today's incident was the same lithium-ion type battery that caught fire on board a JAL Dreamliner in Boston last week. Inspectors found liquid leaking from the battery today, and said it was "discolored."

Japan's transport ministry categorized the problem as a "serious incident" that could have led to an accident.

Even more shaken up than the passengers on the Japanese flight may be the reputation of America's largest plane manufacturer, Boeing.

Since the 787 -- with a body mostly made of carbon fiber -- was introduced, it's had one small problem after another. But the nagging battery issue, which caused an onboard fire at Boston's Logan Airport last week, was serious enough for the FAA to ground the plane.

"It's a rough couple weeks for Boeing and ANA," said John Hansman, an MIT professor of aeronautics and astronautics. "I think clearly in the short term this type of bad press has been tough for Boeing. I think in the long haul, this is a good airplane. It's in a good market."

Why musical genius comes easier to early starters

Good news for pushy parents. If you want your child to excel musically, you now have better justification for starting their lessons early. New evidence comes from brain scans of 36 highly skilled musicians, split equally between those who started lessons before and after the age of 7, but who had done a similar amount of training and practice.

MRI scans revealed that the white matter in the corpus callosum – the brain region that links the two hemispheres – had more extensive wiring and connectivity in the early starters. The wiring of the late starters was not much different from that of non-musician control participants. This makes sense as the corpus callosum aids speed and synchronisation in tasks involving both hands, such as playing musical instruments.

"I think we've provided real evidence for something that musicians and teachers have suspected for a long time, that early training can produce long-lasting effects on performance and the brain," says Christopher Steele of the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, and head of the team.

Sweet spot

Steele says that younger-trained musicians may have an advantage because their training coincides with a key period of brain development . At age 7 or 8, the corpus callosum is more receptive than ever to the alterations in connectivity necessary to meet the demands of learning an instrument.

However, he stresses that these connectivity adaptations are no guarantee of musical genius. "What we're showing is that early starters have some specific skills and accompanying differences in the brain, but these things don't necessarily make them better musicians," he says. "Musical performance is about skill, but it is also about communication, enthusiasm, style and many other things we don't measure. So while starting early may help you express your genius, it won't make you a genius," he says.

Nor should older aspiring musicians despair. "They should absolutely not give up. It is never too late to learn a skill," says Steele.

SDA's Desmond Lim brands himself as dedicated & determined

SINGAPORE: The Singapore Democratic Alliance's (SDA) Desmond Lim has described himself as a dedicated local and determined leader.

Mr Lim is no stranger to the Punggol East ward, having contested there during the 2011 General Election.

It was a setback that Mr Lim said would have made others run away from politics.

The SDA's secretary-general forfeited his S$16,000 election deposit when he garnered around four per cent of votes in the 2011 General Election.

He said his loss in the Punggol East ward only emboldened him to make a comeback. "In life, we have a lot of hurdles. We have a lot of experiences that (have) no smooth rides. But that doesn't mean that we stop from there. Are we going to tell our children 'oh, you fail your examination, that's it, finish. It's the end of the world. Don't study further.' No, we'll encourage them. Never mind, try again."

Mr Lim's brush with elections began in 2001, when he contested in the then Jalan Besar Group Representation Constituency and was defeated.

He lost again in the 2006 General Election, when he contested in the Pasir Ris-Punggol Group Representation Constituency.

With three elections and 20 years in politics under his belt, Mr Lim thinks he has the necessary qualities to represent Punggol East.

"The Parliament must have a diversified voice. We must have more than one, two parties to counter-check and balance of each other."

Since the 2011 loss, Mr Lim said he has built up a grassroots movement comprising over 10 Punggol residents.

"The residents (themselves) should take up the ownership to advocating for what they really need, such as hawker centre, and because of that, safety - road safety, buses, increase the number of buses service."

Mr Lim plans to set aside a third of his allowance as a Member of Parliament to start a residents' insurance scheme, if elected.

Online courses need human element

Online courses are proliferating, says Douglas Rushkoff, but will really succeed when they bring humanity to learning process

STORY HIGHLIGHTS

• Douglas Rushkoff: Education is under threat, but online computer courses are not to blame


• He says education's value hard to measure; is it for making money or being engaged?


• He says Massive Open Online Courses lack human exchange with teachers


• Rushkoff: MOOCs should bring together people to share studies, maintain education's humanity

Editor's note: Douglas Rushkoff writes a regular column for CNN.com. He is a media theorist and the author of "Program or Be Programmed: Ten Commands for a Digital Age" and "Life Inc.: How Corporatism Conquered the World, and How We Can Take It Back." He is also a digital literacy advocate for Codecademy.com. His forthcoming book is "Present Shock: When Everything Happens Now."

(CNN) -- Education is under threat, but the Internet and the growth of Massive Open Online Courses are not to blame.

Like the arts and journalism, whose value may be difficult to measure in dollars, higher education has long been understood as a rather "soft" pursuit. And this has led people to ask fundamental questions it:

What is learning, really? And why does it matter unless, of course, it provides a workplace skill or a license to practice? Is the whole notion of a liberal arts education obsolete or perhaps an overpriced invitation to unemployment?

Douglas Rushkoff

The inability to answer these questions lies at the heart of universities' failure to compete with new online educational offerings -- the rapidly proliferating MOOCs -- as well as the failure of most Web-based schools to provide a valid alternative to the traditional four-year college.

Education is about more than acquiring skills.

When America and other industrialized nations created public schools, it was not to make better workers but happier ones. The ability to read, write and think was seen as a human right and a perquisite to good citizenship, or at least the surest way to guarantee compliant servitude from the workers of industrial society. If even the coal miner could spend some of his time off reading, he stood a chance of living a meaningful life. Moreover, his ability to read the newspaper allowed him to understand the issues the day and to vote intelligently.

What we consider basic knowledge has grown to include science, history, the humanities and economics. So, too, has grown the time required to learn it all. While the modern college might have begun as a kind of finishing school, a way for the sons of the elite to become cultured and find one another before beginning their own careers, it eventually became an extension of public school's mandate. We go to college to become smarter and more critical thinkers while also gaining skills we might need for the work force.

Accordingly, we all wanted our sons and daughters to go to college until recently. The more of us who could afford it, the better we felt we were doing as a society. But the price of education has skyrocketed, especially in the tiny segment of elite schools. This has led to the widespread misperception that a good college education is available only to those willing to take on six-figure debt.

Worse, in making the calculation about whether college is "worth it," we tend to measure the cost of a Harvard education against the market value of the skills acquired. Did my kid learn how to use Excel? If not, what was the point?

To the rescue come the MOOCs, which offer specific courses, a la carte, to anyone with a credit card; some even offer courses for free.

Following the model of University of Phoenix, which began offering a variety of "distance learning" in 1989, these newer Web sites offer video lectures and forums to learn just about anything, in most cases for a few hundred dollars a class. MOOCs have exploded in the past few years, enrolling millions of students and sometimes partnering with major universities.

For pure knowledge acquisition, it's hard to argue against such developments, especially in an era that doesn't prioritize enrichment for its own sake. But it would be a mistake to conclude that online courses fulfill the same role in a person's life as a college education, just as it would be an error to equate four years of high school with some online study and a GED exam.

Don't get me wrong: I have always been a fan of online education -- but with a few important caveats.

First off, subjects tend to be conveyed best in what might be considered their native environments. Computers might not be the best place to simulate a live philosophy seminar, but they are terrific places to teach people how to use and program computers.

Second, and just as important, computers should not require the humans using them to become more robotic. I recently read an account from an online lecturer about how -- unlike in a real classroom -- he had to deliver his online video lectures according to a rigid script, where every action was choreographed. To communicate effectively online, he needed to stop thinking and living in the moment. That's not teaching; it's animatronics.

Online learning needs to cater to human users. A real instructor should not simply dump data on a person, as in a scripted video, but engage with students, consider their responses and offer individualized challenges.

The good, living teacher probes the way students think and offers counterexamples that open pathways. With the benefit of a perfect memory of student's past responses, a computer lesson should also be able to identify some of these patterns and offer up novel challenges at the right time. "How might Marx have responded to that suggestion, Joe?"

Finally, education does not happen in isolation.

Whether it's philosophy students arguing in a dorm about what Hegel meant, or fledgling Java programmers inspecting one another's code, people learn best as part of a cohort. The course material is almost secondary to the engagement. We go to college for the people.

Likewise, the best of MOOCs should be able bring together ideal, heterogeneous groupings of students based on their profiles and past performance, and also create ample opportunities for them to engage with one another in the spirit of learning.

Perhaps this spirit of mutual aid is what built the Internet in the first place. Now that this massive collaborative learning project has succeeded, it would be a shame if we used it to take the humanity out of learning altogether.

House passes $50.7 billion Sandy relief bill

The storm drove New York and New Jersey residents from their homes, destroyed belongings and forced them to find shelter for themselves - and for their pets, said owners, who recounted tales of a dog swimming through flooded streets and extra food left behind for a tarantula no one was willing to take in. (AP Photo/Craig Ruttle, File) / Craig Ruttle

The House of Representatives today passed a $50.7 billion bill to provide funds for Hurricane Sandy relief as well as other natural disasters. The vote was 241 to 180, with 179 Republicans and one Democrat voting no.

The bill will now move to the Senate, where it is expected to be passed by lawmakers after the new session begins on January 22, though it's possible it could be passed by voice vote this week. It is then expected to be quickly signed into law by President Obama.

The package was divided into two parts: A $17 billion bill for immediate recovery from Sandy, and another $33.7 billion amendment for long-term recovery and investment to limit the damage from similar events in the future. The October storm is believed to be responsible for 140 deaths and billions of dollars in damage centered in New York, New Jersey and Connecticut. It damaged or destroyed hundreds of thousands of homes and businesses and knocked out transit systems and power grids.

The package provides more than $16 billion for the New York and New Jersey transit systems as well as more $16 billion for Housing and Urban Development funding for recovery from Sandy and other disasters. Other funding goes to the Federal Emergency Management Agency's disaster relief aid fund and to Army Corps of Engineers projects to limit future damage. Funding is also authorized for repairs by the Coast Guard, Federal Highway Administration and Veterans Affairs Department.

Lawmakers from the Northeast criticized southern Republican lawmakers who had sought to reduce the size of the package or require that funding be offset with an across the board cut to discretionary spending. An amendment from Rep. Mick Mulvaney, R-S.C., that would have offset the funding with spending cuts failed 162 yeas to 258 nays earlier in the day, and the Republican-led House Rules Committee blocked efforts to reduce the size of the package.

"We are asking, we are pleading and we shouldn't have to beg for money for the Northeast, to be able to survive this tragedy that hit us," said Rep. Rosa Delauro, D-Conn., who added: "I might remind my colleague from Louisiana that between Rita, Wilma and Katrina, this institution appropriated $133.9 billion in disaster relief."

Critics of the bill derided it as "an excuse for a grab-bag of spending, having nothing to do with emergency relief," in the words of Rep. Tom McClintock, R-Calif.

The Senate passed a $60 billion Sandy relief bill before the end of the last Congress, but House Speaker John Boehner, R-Ohio, declined to schedule a House vote on that measure in the wake of the contentious vote on "fiscal cliff" legislation. That decision prompted harsh criticism from northeastern lawmakers, including Rep. Peter King, R-N.Y., and Gov. Chris Christie, R-N.J., forcing Boehner to hastily schedule today's vote in addition to $9.7 billion in flood relief that was passed Jan. 4.

NY Passes Nation's Toughest Gun Law

Today New York became the first state to pass a gun control law -- the toughest in the nation -- since the Sandy Hook Elementary School shooting massacre last month.

Acting one month and a day since the rampage killing that left 20 first-graders and six educators dead, Gov. Andrew Cuomo signed the bill into law shortly after 5 p.m.

Called the New York Safe Act, the law includes a tougher assault weapons ban that broadens the definition of what constitutes an assault weapon, and limits the capacity of magazines to seven bullets, down from 10. The law also requires background checks of ammunition and gun buyers, even in private sales, imposes tougher penalties for illegal gun use, a one-state check on all firearms purchases, and programs to cut gun violence in high-crime neighborhoods.

As he signed the bill into law, Cuomo said it was not only "the first bill" but the "best bill."

"I'm proud to be a New Yorker, because New York is doing something, because we are fighting back, because, yes, we've had tragedies, and yes, we've had too many innocent people lose their lives, and yes, it's unfortunate that it took those tragedies to get us to this point, but let's at least learn from what's happened, let's at least be able to say to people, yes, we went through terrible situations, but we saw, we learned, we responded, and we acted, and we are doing something about it," Cuomo said. "We are not victims.

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

"You can overpower the extremists with intelligence and with reason and with commonsense," Cuomo continued, "and you can make this state a safer state."

New York's law also aims to keep guns out of the hands of those will mental illness. The law gives judges the power to require those who pose a threat to themselves or others get outpatient care. The law also requires that when a mental health professional determines a gun owner is likely to do harm, the risk must be reported and the gun removed by law enforcement.

The legislation also includes what is called a "Webster provision," named for the two firefighters ambushed on Christmas Eve in Webster, N.Y. The measure would mandate a life sentence with no chance of parole for anyone who kills a first responder.

The National Rifle Association issued a statement after the bill's signing, saying it was "outraged at the draconian gun control bill that was rushed through ... late Monday evening."

"Gov. Andrew Cuomo and the New York State Legislature orchestrated a secretive end-run around the legislative and democratic process and passed sweeping anti-gun measures with no committee hearings and no public input," the statement read. "These gun control schemes have failed in the past and will have no impact on public safety and crime. Sadly, the New York Legislature gave no consideration to that reality. While lawmakers could have taken a step toward strengthening mental health reporting and focusing on criminals, they opted for trampling the rights of law-abiding gun owners in New York, and they did it under a veil of secrecy in the dark of night. The legislature caved to the political demands of a governor and helped fuel his personal political aspirations."

Islamists guerrillas flee French air strikes in Mali

BAMAKO: French air strikes forced Islamist guerrillas to flee towns in northern Mali and Paris secured new international support for military action as the militants struck back, seizing a small western town.

The Islamists said they had made a "tactical retreat" from Timbuktu and other key towns where they have imposed a brutal version of Islamic law for nearly 10 months.

But they struck back in western Mali where they took the small town of Diabaly from the country's weakened army, highlighting the daunting campaign ahead to restore order in the West African nation.

French jets on Monday hit Douentza, 800 kilometres (500 miles) from Bamako, which the Islamists have held since September. But residents said the fighters had left before the warplanes arrived.

In Timbuktu, where inhabitants have been executed or had limbs cut off in some of the worst abuses, the Islamists reportedly fled in anticipation of an attack.

"The mujahideen have left. They are really scared," said one resident in the historic city, where the militants have destroyed centuries-old Muslim monuments.

In Gao, another northern city held by the Islamists, the jihadists were nowhere to be seen after bombing by Rafale warplanes on Sunday, residents there said.

At least 60 insurgents were killed in Sunday's assault, according to residents and a security source.

Mali's Foreign Minister Tieman Hubert Coulibaly said in Paris that he believed more than 100 Islamists had been killed in the four days since France launched operations to stem a guerrilla advance towards Bamako.

A spokesman for the Ansar Dine (Defenders of the Faith) group, Senda Ould Boumama, said the withdrawal was a "tactical retreat" to reduce civilian casualties, in comments published on Mauritanian news website Alakhbar.

On top of the use of Rafale fighters and helicopter attacks, about 650 French troops are in Mali to halt the Islamist advance, according to the French defence ministry.

While jolted by France's arrival, the insurgents remained on the offensive in areas where French troops were not yet operating. The militants seized Diabaly, some 400 kilometres (250 miles) north of Bamako.

"We knew there would be a counter-offensive towards the west," French Defence Minister Jean-Yves Le Drian told BFM Television.

"They have taken Diabaly, which is a small town, after heavy fighting and resistance from the Malian army, which was insufficiently equipped at that exact point."

Le Drian acknowledged that French forces were facing a "difficult" situation in the west, where he said the rebels are well armed.

France's Foreign Minister Laurent Fabius hailed the "quasi-unanimous" international backing for the offensive, strongly supported by Mali.

"We cannot simply push them back, we have to chase them away," Coulibaly told French television after meeting Fabius, "We simply now cannot allow a timeout for these forces to reorganise."

A meeting of the 15-nation UN Security Council on Mali also expressed unanimous "understanding and support" for the military intervention, France's UN ambassador Gerard Araud told reporters.

France and other council countries want to speed up the deployment of a UN-mandated 3,300-strong West African intervention force in Mali.

Nigeria, which will lead the force, plans to have 600 troops on the ground "before next week," President Goodluck Jonathan said. Benin, Ghana, Niger, Senegal, Burkina Faso and Togo have also pledged troops.

Britain and Canada have offered military transporters to the French military and the United States said it will share intelligence and provide logistical support.

"I commend France for taking the steps that it has," US Defense Secretary Leon Panetta said.

Algeria said it had closed its 2,000 km (1,250 mile) desert border with northern Mali to stop Islamists crossing into the country.

The Islamists seized upon the chaos of a military coup in Bamako in March to seize northern Mali, sparking widespread international fears that they could set up a terrorist safe haven.

The UN Security Council had given approval for a military offensive that UN officials had said could not be launched until September.

But the Islamist offensive and France's military intervention has led to predictions by diplomats that the plans will be reviewed.

STORY HIGHLIGHTS

• Clarence Thomas known for remaining quiet during oral arguments


• On Monday, he joked about lawyers educated at Yale, his alma mater


• Current Supreme Court known as 'hot bench' for the rhetorical scrum during arguments

Washington (CNN) -- It was just a few words and a joke at that. But Supreme Court Justice Clarence Thomas broke his seven-year long silence on Monday when he spoke at oral arguments.

He made fun of lawyers from Yale, his law school alma mater.

Thomas has become known for rarely commenting on cases from the bench, another reflection of the complex and often misunderstood personality of the court's only African-American jurist.

On Monday, the justices were hearing an argument about the state of Louisiana's delay in paying for counsel for a death penalty defendant. Should that count against the state for the purposes of the right to a speedy trial?

A lawyer for the state was making the case for the inmate's appointed counsel, saying the woman was "more than qualified" and "very impressive."

"She was graduate of Yale Law School, wasn't she?" said Justice Antonin Scalia in apparent support, noting another member of the legal team went to Harvard.

The next words were hard to hear in the back-and-forth between the justices. But Thomas made a joke about the competence of Yale lawyers when compared to their Harvard colleagues, according to two witnesses.

Six members of the current high court attended Harvard Law School. Thomas, Samuel Alito and Sonia Sotomayor attend Yale.

Sotomayor describes life journey in new memoir

The official transcript released by the court does not capture the flavor of the colorful exchange. But the lawyer arguing before the court was apparently not pleased.

"I would refute that, Justice Thomas," said Carla Sigler, the assistant district attorney in Lake Charles, Louisiana.

The rest of the time, Thomas kept his own counsel as he is known to do.

"One thing I've demonstrated often in 16 years is you can do this job without asking a single question," he recalled in a speech five years ago.

Written opinions remain the main way the court expresses itself. But the current court is known as a "hot bench" for the busy back-and-forth rhetorical scrum during arguments.

Eight of the justices compete for time to make their questions and views known.

Thomas does occasionally speak from the bench when announcing opinions he has written, but before arguments commence.

Off the bench in friendly audiences, he can be gregarious, inquisitive and often self-reflective. He has a booming voice, and his hearty laugh is easily recognizable.

Some scholars have said Thomas' aversion to talking has reached epic heights.

A study of transcripts by Timothy Johnson of the University of Minnesota found in the past four decades, no justice besides Thomas had failed to speak at least once during an entire 12-month term.

The last time he spoke was February 22, 2006, during a capital appeal.

Newtown group aims to prevent violent tragedies

Updated 8:01 p.m. ET

NEWTOWN, Conn. Nicole Hockley says she still finds herself reaching for her son's hand or expecting him to crawl into bed with her for a hug before school.

"It's so hard to believe he's gone," said Hockley, whose son Dylan was among the 20 first-graders and six adults killed by a gunman a month ago at Sandy Hook Elementary School.

She was among several parents to speak Monday at the launch of Sandy Hook Promise, a group calling for a national dialogue to help prevent similar tragedies. Parents held photos of their children, spoke in wavering voices, cried and hugged.

"I do not want to be someone sharing my experience and consoling another parent next time. I do not want there to be a next time," Hockley said.

The group did not offer specific remedies, saying it wants to have open-minded discussions about a range of issues, including guns, mental health and safety in schools and other public places. Several speakers said they did not believe there was a single solution.

"We want the Sandy Hook school shootings to be recalled as the turning point where we brought our community and communities across the nation together and set a real course for change," said group co-founder Tom Bittman.

Adam Lanza, 20, shot his way into the school on Dec. 14 and killed 26 before committing suicide as police arrived. He also killed his mother at their Newtown home.

Jeremy Richman, whose daughter Avielle was killed, said a deeper understanding of mental health issues is essential. He and his wife, Jennifer Hensel, started a foundation to explore issues such as risk factors and successful interventions.

David Wheeler, whose son Benjamin was killed, said he and his wife Francine have spent the past month rededicating themselves to being the best parents to their surviving son Nate.

"What we have recently come to realize is that we are not done being the best possible parents we can be for Ben, not by a very long measure," Wheeler said.

Wheeler emphasized the role of parents.

"I would respectfully request that any parent that hears these words simply pause for a moment and think, ask yourself, what is it worth doing to keep your children safe?" Wheeler said.

Many of the parents have also spoken with national leaders about the issue of gun control. Jackie Barden, who's son Daniel was also killed in the school, told CBS News correspondent Seth Doane she spoke to President Barack Obama.

"I actually mentioned that we were going to be adopting a kitten," Barden said. "I am surprised the process I had to go through -- a lot of forms online. And they called me and interviewed me. And then she was calling me to get some information on our family. I don't know enough about guns, but I think it's a little easier to get a gun than to get a kitten."
