Obama looks to past to set course for future

News Analysis

President Obama is a student of history - it was no coincidence that he formally announced his run to become the first African-American president back in 2007 at the Old State Capitol in Springfield, Illinois, where Abraham Lincoln delivered his "house divided" speech in 1858 - and his inaugural address today drew an unmistakable line between the nation's past and its prospects for the future.

President Obama's second inaugural speech

The president opened his remarks by referencing Lincoln's words from that speech, stating that America came to realize at that point in history that "no union founded on the principles of liberty and equality could survive half-slave and half-free." He grounded his remarks in the Declaration of Independence's claim that "all men are created equal," tying it to both the American Revolution and rules mandating that there is fair play in the free market, to the need for a great nation to "protect its people from life's worst hazards and misfortune."

Later, he again invoked the declaration - though this time, he referred to the notion that "all of us are created equal" - before referencing three landmark moments in the battle for civil rights: The Seneca Falls Convention for women's rights, the clashes in Selma for African-American rights and the riots at New York's Stonewall Inn for gay rights. (The speech marked the first presidential inaugural in which LGBT rights have been referenced.)

He then pivoted from the triumphs of the past to the necessity of continuing the fight, calling for equal pay for women, equal rights for gay men and women, an elimination of long lines to vote, better treatment of immigrants, and, in an indirect reference to his desire to pass gun control legislation, the necessity of children from Detroit to Appalachia to Newtown to know "that they are cared for, and cherished, and always safe from harm."

Brinkley on inaugural address: "A great civil rights speech"

At five separate moments in his second inaugural address, delivered to an estimated 500,000 to 700,000 people at the Capitol, Mr. Obama uttered the words "We, the people" - the opening words to the preamble of the Constitution. Those words were deployed to underscore the president's argument that Americans need to recognize that we are all in it together - and that while America celebrates initiative and enterprise, "preserving our individual freedoms ultimately requires collective action."

"For the American people can no more meet the demands of today's world by acting alone than American soldiers could have met the forces of fascism or communism with muskets and militias," he said. "No single person can train all the math and science teachers we'll need to equip our children for the future, or build the roads and networks and research labs that will bring new jobs and businesses to our shores. Now, more than ever, we must do these things together, as one nation, and one people." He went on to add that "we are made for this moment, and we will seize it - so long as we seize it together."

That idea underscored the positions Mr. Obama reiterated during the speech, which at times came closer to a policy-oriented State of the Union Address than an inaugural, which historically tends to be more about soaring rhetoric. (The president will offer his State of the Union on February 12.) In addition to arguing that economic inequality hampers the nation's success, he said that the future depends on harnessing "new ideas and technology to remake our government, revamp our tax code, reform our schools, and empower our citizens with the skills they need to work harder, learn more, and reach higher."

"We do not believe that in this country, freedom is reserved for the lucky, or happiness for the few," said the president. "We recognize that no matter how responsibly we live our lives, any one of us, at any time, may face a job loss, or a sudden illness, or a home swept away in a terrible storm. The commitments we make to each other - through Medicare, and Medicaid, and Social Security - these things do not sap our initiative; they strengthen us. They do not make us a nation of takers; they free us to take the risks that make this country great."

Mr. Obama also fit a call for a renewed focus on fighting climate change - an issue largely absent from his first-term agenda - into the notion of collective action for the common good, saying that "the failure to [address it] would betray our children and future generations."

Axelrod on Obama's vision for economy

In addition to climate change, Mr. Obama's second term agenda involves pushing passage of gun control and immigration legislation, overseeing the further implementation of the health care law, winding down the war in Afghanistan, and continuing to try to find some way to come to a major agreement with Republicans to address the nation's massive debt and deficit.

He has signaled that to accomplish these goals, he will take a more confrontational approach with Republicans than he did in his first term -- an approach illustrated by his recent refusal to negotiate on raising the debt limit. His inaugural address offered little in the way of appeals for Washington bipartisanship; instead, Mr. Obama called on Americans in and out of the nation's capitol to come together to help the nation stay on the right path, even if the results are sometimes "imperfect."

"Progress does not compel us to settle centuries-long debates about the role of government for all time - but it does require us to act in our time," he said. "For now decisions are upon us, and we cannot afford delay."

It was an appeal grounded in the notion that America's strength comes from all its citizens, no matter their status. And it was offered by a president who knows the debt he owes to history - a president who sees himself both as a symbol of American progress and a vessel to keep it moving forward.

Inauguration: 7.5 Things You Should Have Seen

A presidential inauguration is a big, long event that lasts all day and into the night–and who has time to really watch it? People have jobs, ones that don’t let you off for a federal holiday.

Everyone (or, at least, some) will be talking about it, which means potential embarrassment for anyone who doesn’t know what happened. Thankfully, ABC employs  news professionals stationed in Washington, D.C., to pay attention to these kinds of things and boil off some of the less noteworthy or interesting stuff, presenting you with short videos of everything that really mattered. Or at least the things a lot of people were talking about.

A full day of paying attention to President Obama’s second Inauguration leads one of those professionals to offer these 7 1/2 things:

1. Beyonce Sang the National Anthem

Boy, howdy! Did she ever? Beyonce has essentially become the Obama’s go-to female performer: She recorded a music video for Michelle Obama’s “Let’s Move” initiative in 2011, and she performed at the president’s last inauguration in 2009. Her velvety, soulful “Star Spangled Banner” is getting good reviews.

2. Kelly Clarkson Also Sang

Kelly Clarkson is not as “in” with the First Couple as Beyonce seems to be, but they let her sing “My Country ‘Tis of Thee,” and she did a pretty good job with it. This was kind of weird, though, because at one point she said she loved Ron Paul, although she later said she would vote for Obama.

3.  Obama Talked About Gay Rights

This may not seem shocking since more than half the country, including President Obama, supports gay marriage. But the president made a point of mentioning gay rights during his speech, equating the struggles of the LGBT community with those of  past civil rights movements, and in doing so made history.

He name-checked Stonewall, the New York City bar that was raided by police in 1969 sparking riots to protest the anti-gay crackdown. And he actually used the word “gay”: “Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law – for if we are truly created equal, then surely the love we commit to one another must be equal as well,” Obama said in his address.

Plenty of inaugural addresses have been chock full of rhetoric about freedom and equality, but in the last four years, the political culture surrounding gay rights has changed significantly, as more states legalized same-sex marriage and as broad swaths of the country got more comfortable with homosexuality in general. Obama’s “evolution” on gay marriage, and now his inaugural address, have helped signify that change.

4. Joe Biden Made Jokes and Shook Hands With People

Could we expect anything less?

Here’s how the Vice President toasting Sen. Chuck Schumer instead of President Obama at the big luncheon:  ”I raise my glass to a man who never, never, never operates out of fear, only operates out of confidence, and a guy–I’m toasting you, Chuck.” Watch it:

And here he is, scurrying around and jovially shaking hands with people along the parade route:

5. Richard Blanco Read a Poem That Was Sort of Whitman-esque, But Not Entirely

Cuban-born Richard Blanco became America’s first openly gay, Latino Inauguration poet. He read a nine-stanza poem entitled “One Today,” which set a kind of unifying American tableau scene.

6. Obama and Michelle Walked Around Outside The Limo

President Obama walked part of the parade route, from the Capitol to the White House, with Michelle. They waved to people. It is not entirely abnormal for a president to do this at an inaugural parade. But they walked quite a ways.

7. John Boehner: ‘Godspeed’

The speaker of the House presented American flags to Obama and Biden, telling them: “To you gentlemen, I say congratulations and Godspeed.”

7 1/2. Sasha and Malia Were There. 

Obama’s daughters, Sasha and Malia, were there. They didn’t really do much, but they did wear coats of different shades of purple that got a lot of  attention on Twitter.

Reports of the daughters looking at smartphones and applying lip gloss highlighted their day. As did this .gif of Sasha yawning.

Wind power delivers too much to ignore

Although aesthetic concerns need to be heard, qualms about wind's reliability are wide of the mark, argues energy policy researcher Reg Platt

THE location of the British Isles at Europe's wild and windy western fringe does not always seem like a blessing. But in one important respect it is: the UK has the greatest potential for wind power, both onshore and offshore, of any European country.

Onshore wind power has expanded steadily across the UK in recent years and is a key plank of the country's commitment to greening its electricity supply. But as the turbines have gone up across the countryside, so has the level of opposition. Wind power has become a deeply divisive issue in British politics.

The issue exploded last year when 106 members of parliament, mostly Conservatives representing rural constituencies, signed a letter to Conservative Prime Minister David Cameron. They urged him to cut subsidies for the onshore wind industry, describing wind technology as "inefficient and intermittent".

Things escalated in the autumn when the recently appointed Conservative energy minister, John Hayes, told two newspapers that "enough is enough" and that no new onshore wind farms would be built. He was slapped down by his boss Edward Davey, the secretary of state for energy and climate change and a member of the Liberal Democrat party. But simmering tensions remain at the top level of the coalition government. Another Conservative, finance minister George Osborne, is known to be sympathetic to the anti-wind cause. Wind turbines also became an important point of contention between the parties in a recent by-election.

Two of the anti-wind campaigners' main concerns are the impact of turbines on the beauty of the countryside and the opposition of local people. It is absolutely right that these be taken into account. But they need to be balanced against the bulk of public opinion, which strongly supports the increased use of wind turbines.

Any misgivings must also be balanced against the important role that this technology can play for the UK, both in fulfilling its climate-change commitments and for future economic success.

Anti-wind campaigners frequently make claims about the shortcomings of wind power. Their main complaints are that the turbines are so inefficient that they actually increase carbon dioxide emissions, and so unreliable that they require constant backup from conventional coal and gas-fired stations.

If correct, these claims would be devastating to wind power. But they are not.

My organisation, the Institute for Public Policy Research, recently published a report tackling these questions. Our conclusions are unambiguous. Onshore wind power reduces carbon emissions and is a reliable source of electricity, at least up to the capacity of wind power that is forecast to be installed in the UK by 2020.

To answer the carbon question, we used a simple model of the UK electricity market. As demand increases, say on a weekday morning when people are waking up and getting ready to go to work, power plants increase output to meet it. Plants with the lowest marginal cost - that is, those that can produce additional electricity most cheaply - are selected first by the market. Here wind beats gas and coal, as no fuel is needed to generate electricity.

The upshot is that, in theory, adding wind power to the energy mix should displace coal and gas, and hence cut carbon. This is backed up by empirical data on emissions reductions from wind power in the US.

There is another way of looking at it. In 2011, wind energy contributed approximately 15.5 terawatt-hours of electricity to the UK. If this had been supplied by fossil fuels instead, CO₂ emissions would have been at least 5.5 million tonnes higher, and as much as 12 million tonnes higher.

As for the important matter of reliability, the obvious worry is that because the wind does not always blow, the system will sometimes not be able to supply electricity when needed.

This seems like common sense. However, the reliability of wind power does not depend on the variability of wind. Instead, it depends on how well changes in wind power output can be anticipated.

Forecasts of wind farm output are increasingly accurate, and drops in output can be predicted and compensated for using conventional power stations. In any case, output is surprisingly stable across the country's entire network of wind farms: when the wind isn't blowing in one area, it usually is somewhere else. The relatively small changes that do occur are well within the capabilities of existing systems for balancing supply and demand on the grid.

Even when winter delivers a "long, cold, calm spell" with low temperatures and little wind, the system can cope. This was demonstrated by a two-week period in February 2010 in Ireland, a country that is much more reliant on wind than the UK. It coped perfectly well.

If the UK government caves into pressure and lowers its ambitions for onshore wind, it will make more expensive forms of low-carbon generation a necessity to hit the UK's target of producing 30 per cent of its electricity from renewables by 2020. The result will be even higher electricity bills.

Scaling back on wind would also be a lost opportunity. The natural resource at our disposal, combined with the UK's engineering heritage, could create significant economic growth and jobs.

The concerns of people who do not want wind power on their doorsteps need to be taken into account. We must also be sensitive to the need to preserve areas of natural beauty. But we should not sacrifice important opportunities because of the views of vocal minority groups and their unsubstantiated claims.

Japan, US team probes Dreamliner battery maker

TOKYO: Japanese and American safety inspectors were on Monday probing the company that makes batteries for Boeing's Dreamliner after the aircraft's worldwide fleet was grounded over safety fears.

Aviation regulators were focusing on the lithium-ion batteries as the cause of a glitch that forced an All Nippon Airways (ANA) flight into an emergency landing last week.

Despite the investigation shares in GS Yuasa, which manufactures the batteries for the Dreamliner's advanced electronics systems, were up 0.95 percent to 318 yen in afternoon Tokyo trade.

The Japanese firm is just one of many contractors in a complex global chain that led to three years of delays before Boeing delivered its first 787 to ANA in 2011.

"Engineers from the FAA (US Federal Aviation Administration), Boeing and our aviation bureau started a probe this morning that is mainly focusing on GS Yuasa's production line," said Yasuo Ishii, a transport ministry safety official.

"They are checking on whether there have been any issues in the production process. We still don't know what caused the battery problem and so we are looking into all possibilities."

Ishii said the inspection does not mean authorities think GS Yuasa, headquartered in the western city of Kyoto, was to blame for the problems.

Investigators on Friday released a picture showing the blackened remains of the battery in the ANA plane. They are also inspecting the aircraft's black box which contains data from the flight that may help to assess how the battery was affected.

Boeing's cutting-edge new planes suffered a series of glitches earlier this month, prompting a global alert from the FAA that led to the worldwide grounding of all 50 operational 787s.

The risk of fire from overheating power packs emerged as a major concern after pilots were forced to land a domestic ANA flight on January 16 due to smoke apparently linked to the lithium-ion battery.

US investigators probing a fire on a Japan Airlines 787 after it landed in Boston on January 7 ruled out an overcharged battery as the cause, although the power packs were undergoing further tests.

On Monday, ANA said the Dreamliner's grounding forced it to cancel 335 flights up to next Sunday, affecting nearly 48,000 passengers.

Cancellations on domestic routes from January 16 to January 27 amount to 292 flights for 44,074 passengers, while 43 international flights have been cut, affecting 3,778 passengers, the airline said.

Flights affected include those from Tokyo to San Jose, Seattle and Beijing.

ANA also said it would not receive a Dreamliner that was on order due to the grounding, but declined to say if it would cancel any purchases it has made to date.

"We were supposed to receive our 18th plane from Boeing later this month," a company spokesman said.

"But as the suspension continues, it may be difficult for us to receive it as scheduled. So far, we have no plans to review anything related to our 787 contracts," he added.

ANA and its domestic rival JAL are key Dreamliner customers with Japan's two biggest airlines having ordered a combined 111 aircraft so far.

By the numbers: MLK Day

The third Monday in January is Martin Luther King Jr. Day, a federal holiday of service honoring the civil rights leader.

STORY HIGHLIGHTS

• The third Monday in January is Martin Luther King Jr. Day


• The federal holiday is also the only federal holiday of service


• "Everybody can be great because everybody can serve," Dr. King said

(CNN) -- Martin Luther King Jr. Day is celebrated on the third Monday in January, although Dr. King was actually born on the 15th of January 1929, 84 years ago.

Below are some facts and numbers related to the federal holiday, in which Americans are encouraged to participate in a day of service.

27 -- The number of years since the very first national celebration of Dr. Martin Luther King Jr. Day on January 20, 1986.

1 -- The Montgomery Bus Boycott against segregated seating lasted approximately one year, starting December 1, 1955. This is what Dr. Martin King said in his book, "Stride Toward Freedom: The Montgomery Story": We have no alternative but to protest. For many years we have shown an amazing patience. We have sometimes given our white brothers the feeling that we liked the way we were being treated. But we come here tonight to be saved from that patience that makes us patient with anything less than freedom and justice.

1 -- In a speech delivered one day before his assassination Dr. King said, "Let us keep the issues where they are."

"That's all this whole thing is about. We aren't engaged in any negative protest and in any negative arguments with anybody. We are saying that we are determined to be men. We are determined to be people," he said.

44 -- "Everybody can be great because everybody can serve," Dr. King said in his sermon "The Drum Major Instinct," forty-four years ago on February 4, 1968. Mrs. King read the same statement when, in 1994, she asked congress to make the holiday an official national day of humanitarian service.

4 -- The number of days between the assassination of Dr. King on April 4, 1968, and the first legislative bill to establish a federal holiday. Rep. John Conyers (D- Michigan) sponsored the bill on April 8, 1968, 44 years ago.

33 -- The number of years since Stevie Wonder's release of "Happy Birthday," a song asking, in 1980, for a day "in full remembrance."

6 million -- The number of signatures on the King Center petitions Mrs. Coretta Scott King and Stevie Wonder presented in 1982 to Tip O'Neil, Speaker of the U.S. House of Representatives, in support of a federal holiday.

29 -- The number of years since President Reagan signed the November 3, 1983, legislation creating the national holiday, which started in 1986. It was almost 11 years later that the holiday became a day of service, August 23, 1994, when President Clinton signed the Martin Luther King Jr. Federal Holiday and Service Act.

3 -- Utah, New Hampshire, and South Carolina were the last to join the rest of the states in making Martin Luther King Jr. Day, the day as we know it throughout the nation.

30 -- feet. The height of the Martin Luther King Jr. Memorial Stone of Hope on the National Mall. On one side, it reads, "Out of the mountain of despair, a stone of hope," from Dr. King's speech, "I Have a Dream," presented at the Lincoln Memorial, August 28, 1963.

1 -- This is the number of federal holidays of service - A Day On, Not a Day Off.

MLK's "content of character" quote inspires debate

"I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character."

This sentence spoken by the Rev. Martin Luther King Jr. has been quoted countless times as expressing one of America's bedrock values, its language almost sounding like a constitutional amendment on equality.

Martin Luther King III talks his father's legacy

King, Civil Rights Act remembered

Yet today, 50 years after King shared this vision during his most famous speech, there is considerable disagreement over what it means.

The quote is used to support opposing views on politics, affirmative action and programs intended to help the disadvantaged. Just as the words of the nation's founders are parsed for modern meanings on guns and abortion, so are King's words used in debates over the proper place of race in America.

As we mark the King holiday, what might he ask of us in a time when both the president and a disproportionate number of people in poverty are black? Would King have wanted us to completely ignore race in a "color-blind" society? To consider race as one of many factors about a person? And how do we discern character?

For at least two of King's children, the future envisioned by the father has yet to arrive.

"I don't think we can ignore race," says Martin Luther King III.

"What my father is asking is to create the climate where every American can realize his or her dreams," he says. "Now what does that mean when you have 50 million people living in poverty?"

Bernice King doubts her father would seek to ignore differences.

"When he talked about the beloved community, he talked about everyone bringing their gifts, their talents, their cultural experiences," she says. "We live in a society where we may have differences, of course, but we learn to celebrate these differences."

The meaning of King's monumental quote is more complex today than in 1963 because "the unconscious signals have changed," says the historian Taylor Branch, author of the acclaimed trilogy "America in the King Years."

Fifty years ago, bigotry was widely accepted. Today, Branch says, even though prejudice is widely denounced, many people unconsciously pre-judge others.

"Unfortunately race in American history has been one area in which Americans kid themselves and pretend to be fair-minded when they really are not," says Branch, whose new book is "The King Years: Historic Moments in the Civil Rights Movement."

Branch believes that today, King would ask people of all backgrounds - not just whites - to deepen their patriotism by leaving their comfort zones, reaching across barriers and learning about different people.

"To remember that we all have to stretch ourselves to build the ties that bind a democracy, which really is the source of our strength," Branch says.

Bernice King says her father is asking us "to get to a place - we're obviously not there - but to get to a place where the first thing that we utilize as a measurement is not someone's external designation, but it really is trying to look beyond that into the substance of a person in making certain decisions, to rid ourselves of those kinds of prejudices and biases that we often bring to decisions that we make."

That takes a lot of "psychological work," she says, adding, "He's really challenging us."

For many conservatives, the modern meaning of King's quote is clear: Special consideration for one racial or ethnic group is a violation of the dream.

The quote is like the Declaration of Independence, says Roger Clegg, president of the Center for Equal Opportunity, a conservative think tank that studies race and ethnicity. In years past, he says, America may have needed to grow into the words, but today they must be obeyed to the letter.

"The Declaration of Independence says all men are created equal," Clegg says. "Nobody thinks it doesn't really mean what it says because Thomas Jefferson owned slaves. King gave a brilliant and moving quotation, and I think it says we should not be treating people differently on the basis of skin color."

Many others agree. King's quote has become a staple of conservative belief that "judged by the color of their skin" includes things such as unique appeals to certain voter groups, reserving government contracts for Hispanic-owned businesses, seeking more non-white corporate executives, or admitting black students to college with lower test scores.

In the latest issue of the Weekly Standard magazine, the quote appears in the lead of a book review titled "The Price Was High: Affirmative Action and the Betrayal of a Colorblind Society."

Considering race as a factor in affirmative action keeps the wounds of slavery and Jim Crow "sore and festering. It encourages beneficiaries to rely on ethnicity rather than self-improvement to get ahead," wrote the author, George Leef.

Last week, the RightWingNews.com blog included "The idea that everyone should be judged by the content of their character, not the color of their skin" in a list of "25 People, Places and Things Liberals Love to Hate."

"Conservatives feel they have embraced that quote completely. They are the embodiment of that quote but get no credit for doing it," says the author of the article, John Hawkins. "Liberals like the idea of the quote because it's the most famous thing Martin Luther King said, but they left the principles behind the quote behind a long time ago."

Obamas Share the Love, Even for Michelle's Bangs

Jan 20, 2013 10:49pm

(Charles Dharapak/AP Photo)

President Obama used the first public remarks of his second term to address what he called the “most significant” event of this weekend: his wife’s much-talked-about new haircut.

“I love her bangs,” Obama told supporters at an inaugural reception at the National Building Museum. “She looks good. She always looks good.”

First lady Michelle Obama, wearing a black sequined cocktail dress and showcasing her new hairdo, also heaped compliments on her husband.

“Let me tell you, it has just been a true thrill to watch this handsome, charming individual grow into the man and the president that he is,” she said, as she reached out to playfully touch the president’s face, sparking laughter from the crowd.

Praising his compassion and courage, the first lady introduced the president as the “love of her life.”

Obama, who was sworn in for a second term in a small White House ceremony earlier today, kept his remarks short, noting he has another big speech to deliver Monday.

“There are a limited amount of good lines and you don’t want to use them all up tonight,” he joked.

Because the Constitutionally mandated date for the inauguration, Jan. 20, fell on a Sunday this year, the traditional, public ceremony was delayed until Monday.

Saving the best for his official inaugural address, the president instead dedicated the bulk of his remarks to thanking supporters for their hard work and dedication to getting him re-elected.

“You understood this was not just about a candidate; it was not just about Joe Biden or Barack Obama. This was about us, who we are as a nation, what values we cherish, how hard we’re willing to fight to make sure that those values live not just for today but for future generations,” he said.

“All of you here understood and were committed to the basic notion that when we put our shoulders to the wheel of history, it moves… It moves forward. And that’s part of what we celebrate when we come together for inauguration,” he said.

Earth may be crashing through dark matter walls

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

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

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

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

Bubbly cosmos

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

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

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

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

Network needed

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

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

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

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

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

China 'strongly dissatisfied' with US island remarks

BEIJING: China said it was "strongly dissatisfied" Sunday after US Secretary of State Hillary Clinton issued a veiled warning to Beijing not to challenge Tokyo's control of disputed islands at the centre of a bitter territorial row.

China is "strongly dissatisfied with and resolutely opposes" the remarks, Foreign Ministry spokesman Qin Gang said in a statement on the ministry's website.

The maritime dispute, which has simmered off and on for years, intensified last year when the Japanese government nationalised islands in the small chain it did not already own, triggering angry responses in China.

China has since increased maritime and air patrols near the East China Sea territory, and in further escalations in recent weeks both Beijing and Tokyo have scrambled fighter jets, though there have been no clashes.

"We urge the US side to treat the issue of the Diaoyu islands with a responsible attitude," Qin said, referring to the territory by its Chinese name. Japan calls the islands the Senkakus.

He also called for Washington to be "careful in words, cautious in actions" and to take "realistic actions to protect the peace and stability of the region and Chinese-US relations".

Qin's statement came after Clinton on Friday said the US opposed "any unilateral actions that would seek to undermine Japanese administration" of the islands.

Clinton, speaking at a press conference with Japanese Foreign Minister Fumio Kishida in Washington, did not mention Beijing directly but said she wanted China and Japan to settle the issue peacefully.

"We do not want to see any action taken by anyone that could raise tensions or result in miscalculation that would undermine the peace, security and economic growth in this region," she said.

The US insists it is neutral on the ultimate sovereignty of the islands but also says they are under Japan's de facto administration.

China has persistently criticised the US position and Beijing's sending of maritime surveillance ships to the potentially gas-rich area is seen by experts as a way to contest the notion of Japanese control.

Complicating the issue is a security treaty that obliges the US -- which keeps military bases in Japan -- to aid the country in the event it is attacked.

Another factor that has raised tensions is the coming to power last month of hawkish Japanese Prime Minister Shinzo Abe, whose party won a landslide victory in elections.

Last week, state media said China will carry out a geographical survey of the islands and also reported that China's armed forces have been instructed to raise their fighting ability in 2013 with "the objective of being able to fight and win a battle".

China's official reaction to Clinton's comments came a day after state media harshly criticised them.

The official Xinhua news agency called it "unwise" for Washington "to throw support behind Japan in Tokyo's islands dispute with Beijing", adding: "This unbalanced position has betrayed its declared intention to stay neutral on the issue."

At least 55 dead in gas plant siege

STORY HIGHLIGHTS

• Algeria: About 685 Algerian workers and 107 foreigners are freed


• Algeria has not specified the nationalities of hostages killed


• Among the 32 militants killed, only three were Algerians, officials say

(CNN) -- The hostage crisis in eastern Algeria is over, but the questions remain.

Among them, exactly how many people are unaccounted for at a remote natural gas facility after three days of chaos that ended Saturday, leaving 23 hostages and dozens of Islamist militants dead.

Some 685 Algerian workers and 107 foreigners were freed, the Algerian interior ministry said.

The White House, in a statement Saturday night, said it remained in close contact with the Algerian government to "gain a fuller understanding of what took place."

The State Department, meanwhile, warned against travel to Algeria.

In the United Kingdom, British Foreign Secretary William Hague echoed the White House's remarks, saying his government too was "working hard to get definitive information" about each individual.

Americans and Britons were among those held hostage, as were workers from various other nations.

Algeria has not specified the nationalities of the hostages killed.

Japan, for example, said Sunday that 10 of its nationals were yet to be confirmed safe.

"As such, we are taking the government announcement that there were multiple Japanese killed extremely seriously," said a spokesman for JGC Corp., an engineering firm that was involved in gas production in In Amenas.

Algeria said that among the 32 militants killed, only three were Algerians; the rest were from other countries.

In a statement Saturday, the Algerian interior ministry said the military found a number of "foreign military uniforms" in its sweep of the facility to clear it of mines planted by militants.

Raids turn deadly

Militants in pickup trucks struck the sprawling gas complex in In Amenas at dawn Wednesday, gathered the Westerners who worked there into a group and tied them up.

The plant is run by Algeria's state oil company, in cooperation with foreign firms such as Norway's Statoil and Britain's BP -- and as such, employed workers from several foreign countries.

The kidnappers wielded AK-47 rifles and put explosive-laden vests on some hostages, according to a U.S. State Department official.

Algeria said the attack was in retaliation for allowing France to use Algerian airspace for an offensive against Islamist militants in neighboring Mali.

But regional analysts believe it was too sophisticated to have been planned in days.

The next day, Algerian special forces moved in because the government said the militants wanted to flee for Mali.

The Islamic extremists also planned to blow up the gas installation, and rigged it with mines throughout, the U.S. official said.

Thursday's military incursion succeeded in freeing some hostages -- but not all.

Some survivors described their harrowing escapes by rigging up disguises, sneaking to safety with locals, and in at least one case, running for his life with plastic explosives strapped around his neck.

Several hostages died. And the Algerian military came under criticism from some quarters for unnecessarily endangering the lives of the hostages.

Undeterred, government followed with a second push Saturday. That assault killed the remaining hostage-takers, but resulted in more hostage deaths.

The army intervened "to avoid a bloody turning point of events in this extremely dangerous situation," the Algerian interior ministry said Saturday.

"It was clear that the terrorists were determined to escape the country with the captives, and to bomb the gas installations."

British Defense Secretary Philip Hammond called the loss of life "appalling and unacceptable," but laid the blame solely on the terrorists.

Now, individual nations are scrambling to find out what happened to their citizens. It is not clear how many hostages were seized by the Islamist militants in the first place.

Colombia

Colombia's president said a citizen was presumed dead.

France

There are no known French hostages unaccounted for, the defense ministry said Saturday.

One man -- identified as Yann Desjeux -- died after telling the French newspaper Sud Ouest on Thursday that he and 34 other hostages of nine different nationalities were well-treated.

Japan

There are still 10 Japanese who have yet to be confirmed safe, JGC -- the engineering firm -- said Sunday.

Malaysia

Three hostages were on their way back to Malaysia, the country's state-run news agency said Sunday. But there is a "worrying possibility" that another is dead while a fifth is unaccounted for, the agency said.

Norway

Five Norwegians are missing while eight are safe, Norwegian Prime Minister Jens Stoltenberg said.

Romania

One Romanian lost his life, the country's foreign ministry said Saturday. Four other Romanians were freed.

United Kingdom

Five British nationals and one UK resident are missing or feared dead, Hague said Saturday. This is in addition to one Briton, whose death was previously announced.

The Scottish government said eight of its residents are safe.

United States

At least one American, identified as Frederick Buttaccio, is among the dead, the State Department said. Six freed Americans left Algeria and one remained.
