Battery expert: "I would not fly in a Dreamliner"

(CBS News) WASHINGTON - Investigators say they still don't know what caused batteries to burn in two Boeing 787 Dreamliners, and until they figure that out and how to fix the problem, none of the planes will be allowed to fly.

More than any other plane, the Dreamliner relies on lithium ion batteries to help power its advanced electrical system. They're lighter and more powerful than older battery types, but they contain a highly flammable liquid electrolyte.

Federal investigators are examining the disassembled battery from the 787 that caught fire in Boston January 7, spewing molten electrolyte.

George Blomgren worked for Eveready, a batteries and flashlights company, for 40 years. He says lithium ion batteries are bundled together for the 787, and that increases the risk.

"These fires burn at very high temperatures, so they are just very dangerous fires," he said.

The Boston fire, and the burned-out battery on a Dreamliner in Japan, is not the first time lithium ion batteries have caused problems.

In 2011, a Chevy Volt lithium ion battery was damaged in a crash test. Three weeks later, it burst into flames. Chevrolet installed a number of fixes to prevent fires.

Safety features also were added to lithium ion batteries in some cell phones and laptops after 56 million were recalled for risk of overheating and exploding.

Boeing says lithium ion batteries "best met the performance and design objectives of the 787" and "Based on everything we know at this point, we have not changed our evaluation."

Blomgren considers the safety of lithium ion batteries on planes questionable.

"From what I know about incidents, I would not fly in a Dreamliner tomorrow. I just wouldn't feel that it was appropriate or safe," Blomgren said.

Many experts believe in the promise of lithium ion batteries, including for airlines, but they just aren't sure its safety has been perfected.

It's Official: Women Will Serve in Combat













Women will soon be able to serve in combat, as things officially changed with the stroke of a pen today at the Pentagon.


At a joint news conference, Secretary of Defense Leon Panetta and Joint Chiefs of Staff Charman Gen. Martin Dempsey signed a memorandum rolling back a 1994 directive prohibiting women from doing so.


"They serve, they're wounded, and they die right next to each other," Panetta said of women and men in the military. "The time has come to recognize that reality.


"If they're willing to put their lives on the line, then we need to recognize that they deserve a chance," Panetta said, noting that he wants his own granddaughters and grandsons to have the same opportunities in their lives and careers.


The change won't be immediate, however. While Panetta announced that thousands of new positions will now be open to women, he has asked the military branches to submit plans by May on how to integrate women into combat operations. He set a January 2016 deadline for branches to implement the changes, giving military services time to seek waivers for certain jobs.


Both Panetta and Dempsey said they believe the move will strengthen the U.S. military force.

"Ultimately, we are acting to strengthen the armed forces," Dempsey said. "We will extend opportunities to women in a way that maintains readiness, morale and unit cohesion."


Women have already served in combat in Iraq and Afghanistan, as ABC News' Martha Raddatz and Elizabeth Gorman reported in 2009: Prohibited from serving in roles "whose primary mission is to engage in direct combat on the ground," women in support roles, nonetheless, served in support roles on the frontlines, where they have fought, been wounded and died.


Women have also flown combat missions since 1993 and have served on submarines since 2010.


Panetta noted that 152 women have died serving in the U.S. military in Iraq and Afghanistan. Dempsey said he realized a change was inevitable when he noticed two female turret gunners protecting a senior military officer.


"It's clear to all of us that women are contributing in unprecedented ways to the military's mission of defending the nation," Panetta said. "Women represent 15 percent of the force of over 200,000 [and] are serving in a growing number of critical roles on and off the battlefield.


"I've gone to Bethesda to visit wounded warriors, and I've gone to Arlington to bury our dead. There's no distincton."


Panetta and Dempsey said President Obama supported the move, while warning them to maintain military readiness as they considered the change.


Obama hailed the move in a written statement


"Today, by moving to open more military positions -- including ground combat units -- to women, our armed forces have taken another historic step toward harnessing the talents and skills of all our citizens," he said.


"This milestone reflects the courageous and patriotic service of women through more than two centuries of American history and the indispensable role of women in today's military," Obama said.

To spot a fit partridge, check out its 'necklace'









































HOW do you spot a fit partridge? Check out the fractals round its neck.











Fractal geometry is used when a pattern is too complex to be described by Euclidean geometry. It has been applied to coastlines, plant structures and animals' foraging patterns. Lorenzo Pérez-Rodríguez at the National Museum of Natural Sciences in Madrid, Spain, and colleagues wanted to see if it could also be helpful when analysing the complex plumage patterns of birds.













Using images fed into software, the team found that red-legged partridges with a more gradual transition between the plain and spotted areas of their bib have a higher fractal dimension (FD) - a measure of a pattern's complexity.












To see if this was linked to the bird's fitness, they compared the bibs of 68 birds of both sexes, half of which were on a restricted diet. After six months, the bibs of undernourished birds had a lower FD than before their food was reduced. Low FD also predicted poorer immune responsiveness.












Pérez-Rodríguez thinks that a fractal-rich bib could be used to advertise the health of the bird to potential mates. "Birds have quite a different visual system to ours," says Thanh-Lan Gluckman at the University of Cambridge, so the work could also help us understand what one bird sees in another.

Networking more important than getting pay rise: survey






SINGAPORE: Eighty-five per cent of Singaporean professionals surveyed actually plan to make a New Year resolution related to their professional life or career this year - up from the 67 per cent who did in 2012 and in contrast to how only 54 per cent of them make New Year resolutions in general.

Four hundred and fifty professionals were involved in the survey by LinkedIn, the world's largest professional network.

The top five professional goals that Singaporeans want to achieve in 2013 are professional development through learning new skills, network more or build more professional relations, getting promoted or move into a leadership role, getting a new job or career and getting a pay rise.

LinkedIn also asked Singaporean professionals what they wanted to achieve with these professional goals and the top choice was financial security and growth, followed by having stronger workplace performance and better work-life balance.

Gergen: Speech deepens divisions






STORY HIGHLIGHTS


  • David Gergen says historians will look on Obama's speech as an important source

  • Obama seemed liberated to express his philosophy of government, he says

  • Gergen says the president stressed equality in the tradition of Lincoln, King

  • He says GOP is bristling at the speech, and it will likely deepen divisions in Washington




Editor's note: David Gergen is a senior political analyst for CNN and has been an adviser to four presidents. A graduate of Harvard Law School, he is a professor of public service and director of the Center for Public Leadership at Harvard University's Kennedy School of Government. Follow him on Twitter.


(CNN) -- Years from now, historians are likely to look back upon Barack Obama's second inaugural address as a rich treasure trove for understanding his presidency and possibly the course of American politics.


It wasn't as important for his rise to power as his 2004 address to the Democratic National Convention. That one propelled him onto the national stage. It wasn't as elegant as his Philadelphia speech on race relations in the 2008 campaign. That one was his rhetorical masterpiece. But the second inaugural was far more important than either in defining his political philosophy as president.


Politics: After inauguration, political reality returns to Washington


Here's a first rough draft of what historians may find significant:



David Gergen

David Gergen



Obama revealed: The Obama who took the oath of office this week seemed not only more confident but also liberated. A central point of his address was that he inherited an economic crisis and two wars but now the nation is emerging into a clearing. This, he believes, is a golden opportunity for fresh action -- a moment to be seized.


Left unspoken were two other reasons why he feels liberated: He clearly thinks he has shown the country that Republicans aren't willing to compromise, so that he has no choice but to try to muscle them.


The GOP has now blinked twice on the fiscal cliff and the new debt ceiling; he plans to make them keep blinking. Then, too, Obama is also freed up because he is no longer working under the shadow of the 2010 midterm elections when he was snookered. After his convincing win in 2012, he is back on top politically.


Opinion: Obama's ringing defense of liberalism


All of this has inspired the president to reveal to the world his true political philosophy: In one speech, he gave the strongest embrace of 20th-century liberalism since Lyndon Johnson and the Great Society. Yes, he gave a couple of bows to the importance of individual initiative and private enterprise, but the heart and soul of the address was a call to collective action on a wide array of fronts.


Gone were the third way of Bill Clinton and the centrism of Jimmy Carter. He emerged as an unapologetic, unabashed liberal -- just what the left has long wanted him to be and exactly what the right has feared.


Heir to Lincoln and King: A little more than three decades ago, Ronald Reagan moved the inaugural ceremony from the east side of the Capitol to the west. For Reagan, the symbolism was that of a Californian who wanted to give his inaugural address gazing out across the National Mall, the monuments and Arlington Cemetery toward the Pacific. But for Obama, the symbolism was very different: He was the president who looked west toward the monuments of Abraham Lincoln and the Rev. Martin Luther King Jr. and his address artfully tied him to their legacy.


The historian Garry Wills won a Pulitzer Prize some years ago with his book on Lincoln's Gettysburg Address in 1863. Wills argued that for most of America's early history, people thought that the republic was born with the Constitution of 1787 and the Declaration of Independence was a secondary document.


Opinion: Anti-government era is over








Along came Lincoln at Gettysburg saying that the country was born "four score and seven years ago" -- in 1776 with the declaration. In Wills' view, now widely accepted, Lincoln at Gettysburg turned the declaration's second paragraph into the founding creed of the country. What we must aspire to, Lincoln was saying, was to ensure that all are created equal.


King came to the Lincoln Memorial 100 years later -- in 1963 -- to go back to Lincoln at Gettysburg and through him to the declaration. The nation, King said, must live up to the promise of equal opportunity -- and indeed, that was the dream he so eloquently expressed in the finest American speech since Gettysburg.


Enter Obama at his second inaugural, not only on King's official holiday but 50 years after "I Have a Dream" and 150 years after Gettysburg. The president's address begins with a recitation of the declaration, calls it our "founding creed" and makes the aspiration of equal opportunity the central goal of his presidency.


In the past, presidents at inaugurations have found the nation's heroes among those who have died in battle. Obama chose a different path: He found the nation's heroes at Seneca Falls, Selma and Stonewall. His philosophy, as we learned, is not just about government programs but about embracing inclusion and diversity. It was, I believe, his firmest attempt to build upon Lincoln and King -- and in effect, his address made him their modern heir.


Opinion: GOP, play offense in Obama's second term


Setting a new course: A president's inaugural address often sets the tone and direction of his next four years in office and nowhere may that be more true than with Obama's second. His assertive address has heartened his supporters so that they seem ready to march into battle with him. They not only want him to succeed, but they now have an ambitious agenda to embrace as well.


Smartly, the president's team began putting together a new citizens group, Organizing for Action, just before the inauguration, and his speech was in effect a call to arms. Whether "OFA", as Democrats in Washington already call it, will work well with the Democratic Party is open to question, but it is clear that Obama & Co. intend to use it as an important way to rally public pressure on Congress for his agenda.

On the other side of the aisle, many Republicans such as Eric Cantor were respectful of the president after his address but underneath most of them were bristling. They had expected the president to issue a ritualistic plea for bipartisanship and then to begin negotiating with them over federal deficits.


Instead, he made it clear that he will work with them as long as they agree with him and try to run over them if they resist. From the GOP perspective, Obama was virtually dismissive of the nation's fiscal threats and wasn't interested in true negotiations. In a tweet after the speech, scholar Ian Bremmer captured their view of Obama's message to the GOP: "Together, we shall pursue my objectives."


Opinion: World to Obama -- You can't ignore us


In short, the divisions in Washington may grow even deeper in the near term, if that is possible, and no one knows what will actually be accomplished. Among partisans on both sides, there is still a sense that a piece of gun control can be passed (starting with background checks) and perhaps a larger piece of immigration (starting with H-1B visas and legal status for the undocumented). But serious action on climate change seems distant.


More centrally, the parties seem even further apart on a budget agreement. The GOP is in no mood to revisit higher taxes and the president's address gave a ringing endorsement to the basic structure of Medicare, Medicaid and Social Security. In short, the road ahead looks even rockier than it seemed after the elections.


On the day before the inaugural, a New York Times article by Jodi Kantor reported that after the first term, Obama has warned possible candidates for his job that it is very difficult to get things done in Washington and that the president has a "contracted sense of possibility." He and his team are also aware that power seeps away quickly in a second term.


How, one wondered, is it possible to reconcile those views with Obama's decision to go big at the inaugural, pushing an extraordinarily ambitious agenda.


That question still lingers after the inauguration. It is just possible that what he was ultimately doing in his address was to present the country with a liberal vision of the future and a legislative agenda to go with it -- something akin to what Franklin Roosevelt did in 1944. FDR left behind a Democratic Party with a majority coalition and an agenda that drove American politics for more than 20 years.


Is that the legacy that Obama really wants to leave? Lincoln, King, FDR -- all rolled into one? Only historians will know the answer for sure.

Romney to be honored Friday at D.C. luncheon

Mitt Romney will make it to Washington, D.C. for inauguration week after all.

The 2012 GOP presidential nominee and his wife Ann are scheduled to attend a luncheon in their honor Friday at Washington's J.W. Marriott hotel, National Journal reported this afternoon. The reception will be hosted by two of Romney's biggest campaign fundraisers: Virginia philanthropist Catherine Reynolds and hotel tycoon Bill Marriott, Jr.

Romney, a longtime friend to the Marriott family, serves on Marriott International's board of directors. While on the trail, he and his traveling staff stayed almost exclusively at Marriott hotels.

Having opted to spend Inauguration Day at his home in La Jolla, Calif., on Monday, Romney became the first presidential nominee since Michael Dukakis in 1989 to not attend the ceremonial event. But he's made at least one appearance in the nation's capital since the election: Several weeks following his loss, he enjoyed a lunch of white turkey chili with President Obama at the White House.

Pentagon to Allow Women in Combat













Defense Secretary Leon Panetta will lift a longstanding ban on women serving in combat, according to senior defense officials.


The services have until this May to come up with a plan to implement the change, according to a Defense Department official.


That means the changes could come into effect as early as May, though the services will have until January 2016 to complete the implementation of the changes.


"We certainly want to see this executed responsibly but in a reasonable time frame, so I would hope that this doesn't get dragged out," said former Marine Capt. Zoe Bedell, who joined a recent lawsuit aimed at getting women on the battlefield.


The military services also will have until January 2016 to seek waivers for certain jobs -- but those waivers will require a personal approval from the secretary of defense and will have to be based on rationales other than the direct combat exclusion rule.


The move to allow women in combat, first reported by the Associated Press, was not expected this week, although there has been a concerted effort by the Obama administration to further open up the armed forces to women.


The Joint Chiefs of Staff unanimously recommended in January to Secretary Panetta that the direct combat exclusion rule should be lifted.


"I can confirm media reports that the secretary and the chairman are expected to announce the lifting of the direct combat exclusion rule for women in the military," said a senior Defense Department official. "This policy change will initiate a process whereby the services will develop plans to implement this decision, which was made by the secretary of defense upon the recommendation of the Joint Chiefs of Staff."


Chairman of the Joint Chiefs Gen. Martin Dempsey sent Panetta a memo earlier this month entitled, "Women in Service Implementation Plan."

"The time has come to rescind the direct combat exclusion rule for women and to eliminate all unnecessary gender-based barriers to service," the memo read.


"To implement these initiatives successfully and without sacrificing our warfighting capability or the trust of the American people, we will need time to get it right," he said in the memo, referring to the 2016 horizon.


Women have been officially prohibited from serving in combat since a 1994 rule that barred them from serving in ground combat units. That does not mean they have been immune from danger or from combat.


As Martha Raddatz reported in 2009, women have served in support positions on and off the frontlines in Iraq and Afghanistan, where war is waged on street corners and in markets, putting them at equal risk. Hundreds of thousands of women deployed with the military to those two war zones over the past decade. Hundreds have died.

"The reality of the battlefield has changed really since the Vietnam era to where it is today," said Rep. Tammy Duckworth, D-Ill., a former military helicopter pilot who lost both her legs in combat. "Those distinctions on what is combat and what is not really are falling aside. So I think that after having seen women, men, folks who -- cooks, clerks, truck drivers -- serve in combat conditions, the reality is women are already in combat."


Woman have been able to fly combat sorties since 1993. In 2010, the Navy allowed them on submarines. But lifting restrictions on service in frontline ground combat units will break a key barrier in the military.

Panetta's decision will set a January 2016 deadline for the military service branches to argue that there are military roles that should remain closed to women.


In February 2012 the Defense Department opened up 14,500 positions to women that had previously been limited to men and lifted a rule that prohibited women from living with combat units.


Panetta also directed the services to examine ways to open more combat roles to women.


However, the ban on direct combat positions has remained in place.

MIT website hacked in tribute to Aaron Swartz



Hal Hodson, technology reporter

A tribute to internet activist Aaron Swartz replaced the homepage for the Massachusetts Institute of Technology today, in an apparent act of protest over the university's role in the legal case that led up to Swartz's suicide on 11 Jan.

For a short time, visitors to the MIT.edu home page found a message that read: "R.I.P. Aaron Swartz. Hacked by grand wizard of Lulzsec, Sabu. God Bless America. Down With Anonymous." The background was watermarked with words from a blog post, written by Swartz, titled "Immoral".

Attributing the defacement to "grand wizard of Lulzsec, Sabu" lent the page a sarcastic air, as it's widely known that the former Lulzsec leader was outed as an FBI informant last year.

The attack on MIT's website came amid widespread criticism of how the university handled the case against Swartz, including an article in The New York Times that quoted Swartz's father as saying: "We don't believe [MIT] acted in a neutral way. My belief is they put their institutional concerns first."

According to MIT's service status page, network service was restored within the university as of 1:30 pm EST. The university had not yet returned New Scientist's request for comment when this story was published.

This is the second time since Swartz' death that the MIT site has been the target of attacks. Previously, an MIT sub-domain was replaced with a manifesto for reform of computer and copyright laws. The authors claimed to be operating as a part of the online activist group, Anonymous.

Unilever reports 5.0% profit rise to 4.48b euros






THE HAGUE: Global food and cosmetics giant Unilever reported on Wednesday that net profit last year rose by 5.0 per cent from the 2011 level to 4.48 billion euros (US$5.96 billion).

Unilever, which achieved sales exceeding 50 billion euros for the first time with a figure of 51.3 billion euros, up 10.5 per cent, said the outcome was an important step towards its target of sales of 80 billion euros.

"There is no room for complacency," Unilever chief executive Paul Polman nevertheless warned in a statement.

"Markets will remain challenging, with intense competition and volatile commodity costs."

"We remain focused on achieving another year of profitable volume growth ahead of our markets, steady and sustainable core operating margin improvement and strong cash flow."

Unilever's fourth-quarter sales rose by 7.8 per cent, thanks largely to volume growth of 4.8 per cent, higher than the 6.3 per cent expected on average by analysts interviewed by Dow Jones Newswires.

Underlying sales growth in emerging markets was 11.4 per cent, representing 55.0 per cent of the multinational's global turnover.

"Emerging markets again contributed double-digit growth helping us exceed 50 billion euros turnover, an important milestone in our journey to double the size of Unilever from 40 billion euros to 80 billion euros whilst reducing our environmental impact," Polman said.

The company saw strongest sales growth in Asia-Africa, where the figures rose by 10.6 per cent, while Americas sales were up 7.9 per cent.

Performance in Europe was "sluggish", the company said, with sales up 0.8 per cent.

This reflects "the fragile state of consumer confidence and intensely competitive markets," Unilever said.

Nevertheless, "we have responded to the needs of hard-pressed consumers by providing good quality products at low price points."

"Throughout 2012 our markets experienced markedly different dynamics as emerging markets grew in both volume and value terms whilst developed market value remained subdued, with volumes lower than prior year," Unilever said.

The Anglo-Dutch company said that Magnum ice creams and Sunsilk hair products had become "billion-euros brands", bringing the company's total of such brands to 14.

"We continued to invest behind our brands, again increasing advertising and promotions spend," Polman said, with such spending up 470 million euros.

One of the world's leading suppliers of consumer goods, Unilever owns a wide variety of brands including Knorr, Lipton, Dove and Vaseline. It employs 167,000 workers in 100 countries.
