The world isn't black and white anymore for the super slim PS3.


Sony's Japanese
PlayStation division released information today about several new color options -- Azurite Blue and Garnet Red -- coming soon to the CECH-4000 series PlayStation 3. The reveal follows a German Amazon listing for the same variations that appeared last week.




As with any multi-territory release, what exactly prospective buyers of the new PS3 colors get depends on the region. For example, the European red and blue super slim PS3 packages cost 329.95 Euro ($439) and feature built-in 500GB hard drive, two color-matching Dualshock 3 controllers, and a February 20 release date. In contrast, the Japanese red and blue super slim PS3 runs for 24,980 yen ($278) while only offering a 250GB hard drive and one color-matching controller -- as well as a February 28 release date.


It's fair to say that when and if these colorful PS3 gaming consoles come to the U.S., the packages may likely cost around the $299 baseline seen at retail. Sony did not immediately respond to a request for comment on availability of the red and blue PS3 in the States, but we'll update this post with their response.



You'd probably be able to see this thing from a country mile away.

Attack at Algeria Gas Plant Heralds New Risks for Energy Development



The siege by Islamic militants at a remote Sahara desert natural gas plant in Algeria this week signaled heightened dangers in the region for international oil companies, at a time when they have been expanding operations in Africa as one of the world's last energy frontiers. (See related story: "Pictures: Four New Offshore Drilling Frontiers.")


As BP, Norway's Statoil, Italy's Eni, and other companies evacuated personnel from Algeria, it was not immediately clear how widely the peril would spread in the wake of the hostage-taking at the sprawling In Amenas gas complex near the Libyan border.

Algeria, the fourth-largest crude oil producer on the continent and a major exporter of natural gas and refined fuels, may not have been viewed as the most hospitable climate for foreign energy companies, but that was due to unfavorable financial terms, bureaucracy, and corruption. The energy facilities themselves appeared to be safe, with multiple layers of security provided both by the companies and by government forces, several experts said. (See related photos: "Oil States: Are They Stable? Why It Matters.")


"It is particularly striking not only because it hasn't happened before, but because it happened in Algeria, one of the stronger states in the region," says Hanan Amin-Salem, a senior manager at the industry consulting firm PFC Energy, who specializes in country risk. She noted that in the long civil war that gripped the country throughout the 1990s, there had never been an attack on Algeria's energy complex. But now, hazard has spread from weak surrounding states, as the assault on In Amenas was carried out in an apparent retaliation for a move by French forces against the Islamists who had taken over Timbuktu and other towns in neighboring Mali. (See related story: "Timbuktu Falls.")


"What you're really seeing is an intensification of the fundamental problem of weak states, and empowerment of heavily armed groups that are really well motivated and want to pursue a set of aims," said Amin-Salem. In PFC Energy's view, she says, risk has increased in Mauritania, Chad, and Niger—indeed, throughout Sahel, the belt that bisects North Africa, separating the Sahara in the north from the tropical forests further south.


On Thursday, the London-based corporate consulting firm Exclusive Analysis, which was recently acquired by the global consultancy IHS, sent an alert to clients warning that oil and gas facilities near the Libyan and Mauritanian borders and in Mauritania's Hodh Ech Chargui province were at "high risk" of attack by jihadis.


"A Hot Place to Drill"


The attack at In Amenas comes at a time of unprecedented growth for the oil industry in Africa. (See related gallery: "Pictures: The Year's Most Overlooked Energy Stories.") Forecasters expect that oil output throughout Africa will double by 2025, says Amy Myers Jaffe, executive director of the energy and sustainability program at the University of California, Davis, who has counted 20 rounds of bidding for new exploration at sites in Africa's six largest oil-producing states.


Oil and natural gas are a large part of the Algerian economy, accounting for 60 percent of government budget revenues, more than a third of GDP and more than 97 percent of its export earnings. But the nation's resources are seen as largely undeveloped, and Algeria has tried to attract new investment. Over the past year, the government has sought to reform the law to boost foreign companies' interests in their investments, although those efforts have foundered.


Technology has been one of the factors driving the opening up of Africa to deeper energy exploration. Offshore and deepwater drilling success in the Gulf of Mexico and Brazil led to prospecting now under way offshore in Ghana, Mozambique, and elsewhere. (See related story: "New Oil—And a Huge Challenge—for Ghana.") Jaffe says the Houston-based company Anadarko Petroleum has sought to transfer its success in "subsalt seismic" exploration technology, surveying reserves hidden beneath the hard salt layer at the bottom of the sea, to the equally challenging seismic exploration beneath the sands of the Sahara in Algeria, where it now has three oil and gas operations.


Africa also is seen as one of the few remaining oil-rich regions of the world where foreign oil companies can obtain production-sharing agreements with governments, contracts that allow them a share of the revenue from the barrels they produce, instead of more limited service contracts for work performed.


"You now have the technology to tap the resources more effectively, and the fiscal terms are going to be more attractive than elsewhere—you put these things together and it's been a hot place to drill," says Jaffe, who doesn't see the energy industry's interest in Africa waning, despite the increased terrorism risk. "What I think will happen in some of these countries is that the companies are going to reveal new securities systems and procedures they have to keep workers safe," she says. "I don't think they will abandon these countries."

Live Updates: Obamas Watch Inaugural Parade


Four years and one day after President Obama first took his first oath of office, America is once again celebrating his Inauguration. This time the schedule includes performances by Beyonce and Katy Perry, a parade with more than 2,000 members of the military and two Inaugural balls.


Refresh here for updates throughout the day.


Tune in to the ABC News.com Live page on Monday morning starting at 9:30 a.m. EST for all-day live streaming video coverage of Inauguration 2013: Barack Obama. Live coverage will also be available on the ABC News iPad App and mobile devices.


Read Obama’s second Inaugural address here.


All times are in Eastern Standard Time.



5:42 p.m. – The Cheese Stands Alone


The ladies of the Obama clan have left the Presidential Reviewing Stand. The president remains there to watch the rest of the parade, including a group of uni-cyclists from Maine called the “Gym Dandies.”



5:28 p.m. – Obama Inauguration: Who’s Who?

5:22 p.m. – Biden 2016?


Vice President Joe Biden got very friendly with members of the crowd watching the inaugural parade, prompting some to wonder if this isn’t a prelude to his own presidential run.





4:55 p.m. – POTUS on His Blackberry Before the Parade

It may be a day-long celebration for President Obama, but that doesn’t mean he has left work at the office.


Just before members of the military began streaming by the Presidential Reviewing Stand as part of the inaugural parade, Obama could be seen working on what looks like his specially-secured Blackberry.


Beside him, Sasha and Malia whipped out their iPhones, taking photos of their mother and interrupting their father to make him pose with the first lady. The first family had removed their coats, thanks to heat inside the reviewing stand.


And it was also clear President Obama was chewing gum as he head-bobbed along to the marching bands. Today more than ever he looked like Obama: the gum-chewing, Blackberry-checking president of the people.


What’s not clear – who emails the president on inauguration day? And was it Nicorette gum?



4:30 p.m. – Wrapping Up the Route

ABC’s Devin Dwyer reports the President, the first lady, the Vice President and Dr. Biden will soon make their way to the reviewing stand on Pennsylvania Ave. where they will be joined by Congressional leaders, Supreme Court Justices, governors, the Joint Chiefs and White House staff as well as area elementary school students and some of the Tuskegee Airmen and their families, according to the White House.



4:00 p.m. – Obama, Roberts Sign King Bible


ABC’s Avery Miller reports President Obama and Supreme Court Chief Justice John Roberts signed Martin Luther King, Jr.’s Bible today, at the request of the family.


In his life time, it was King’s “traveling Bible,” according to the Presidential Inaugural Committee.


“An avid reader who was constantly on the road, Dr. King typically traveled with a selection of books that included this Bible,” the PIC wrote in a statement about the Bible written when they announced Obama would use it in his ceremony. “It was used for inspiration and preparing sermons and speeches, including during Dr. King’s time as pastor of Dexter Avenue Baptist Church in Montgomery, Alabama.”

3:56 p.m. – Justice Scalia and the Mystery of the Funny Hat


Michelle Obama wasn’t the only one drawing eyes with her fashion choices at the inaugural ceremonies today. Many on Twitter – including Sen. Claire McCaskill, D-Mo., – remarked on Associate Justice Antonin Scalia’s choice of headgear during President Obama’s swearing-in.


Some compared it to Aretha Franklin’s extravagant hat at the 2009 inauguration. Others simply wondered where it came from.


To find that answer, ABC’s Sarah Parnass spoke with Scalia’s former clerk, Kevin Walsh.


Walsh, who now teaches at University of Richmond School of Law, said the association of Catholic lawyers to which he belongs, St. Thomas More Society of Richmond Va., presented Scalia with the hat in 2010.


The hat is a replica of one worn by St. Thomas More in his most iconic portrait, done by Hans Holbein, according to Walsh.


When giving Justice Scalia the hat, the members of the St. Thomas More Society thought it would be a nice memento. “If nothing else it would be suitable for university functions,” Scalia said.


Walsh said the significance of Scalia’s wearing the hat likely doesn’t go beyond function. In the past, Scalia has worn a skull cap, much like the one Justice Breyer sported today. But the skull cap doesn’t have earflaps – the More hat does.


“That one’s warmer,” Walsh said, comparing the hat Scalia wore today with the one he wore to the 2009 inauguration. “I’d say it’s more functional.”


ABC’s Bob Murphy adds this historical background:


Thomas More was the Lord Chancellor or Chief Legal Officer of England when Henry VIII was King. He famously lost his head (the one the hat was made for) rather than reinterpret the laws of divorce and allow the King to dispatch his Queen. He is a hero to the Catholic legal community for his commitment to moral and legal authority over the whim of the chief temporal power.


The ultraconservative Catholic jurist may or may not be making a statement but the significance is interesting.

3:33 p.m. – Obama Pauses for Final Glimpse of Fans


ABC’s Devin Dwyer reports:


After a bruising campaign, and unusually contentious post-election period, President Obama savored his second and final Inauguration Day as a brief respite from political storms and celebratory moment for his hundreds of thousands of adoring supporters.


As he walked off the inaugural platform on the west front of the U.S. Capitol, Obama turned and paused to look out at the crowd on the National Mall, even as his family and other guests continued ahead without him.


“I want to take a look one more time,” Obama was heard saying. “I’m not going to see this again.”


Read more on that poignant moment with the president here.



3:22 p.m. – Obama Makes History Citing Gay Rights in Inaugural Address


ABC’s Shushannah Walshe reports:


President Obama made history in his inaugural address today mentioning the word “gay” and the issue of gay rights for the first time in a speech at the presidential swearing in.


“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 on the Capitol steps after his swearing in.


Obama also mentioned the word Stonewall when citing milestones of the civil right struggle. It was a reference to a riot and subsequent protests over a police raid in June 1969 of the Stonewall Inn, a gay bar in New York City’s Greenwich Village. The president mentioned it along with the first women’s rights convention held in Seneca Falls, N.Y., in 1848 and the civil rights march in Selma, Ala., in 1965.


“We, the people, declare today that the most evident of truths – that all of us are created equal – is the star that guides us still; just as it guided our forebears through Seneca Falls, and Selma, and Stonewall,” Obama said.


Brian Ellner who led the successful campaign to make same sex marriage legal in New York state called the speech “historic.”

3:12 p.m. –  Obama Sticks to His Script in Second Inaugural Address


ABC News’ Michael Falcone reports:


By their very nature, the texts of presidential inaugural addresses become historical documents as soon as they are delivered. Obama’s speech, like all the others before, will be scrutinized for years to come.


So, how closely did President Obama, who is known for his oratorical prowess, hew to the prepared text of his remarks? With the exception of a few minor words,


It turns out he stuck almost exactly to the script.


“We must harness new ideas and technology” became “So we must harness…” and “Let each of us now embrace, with solemn duty and awesome joy, what is our lasting birthright” ended up as “Let us, each of us, now embrace…” He sprinkled in an extra “and” at the beginning of one paragraph and turned a “that is” into “that’s.”


Otherwise, the president delivered the speech he had in front of him with almost no changes.

2:11 p.m. – Obama Address References Civil Rights, Gay Marriage, Immigration


Univision’s Jordan Fabian reports:


Obama, the nation’s first black president, delivered his address on Martin Luther King, Jr. Day and drew strong parallels between the civil rights battles of King’s generation to the social issues facing today. Perhaps most notable was Obama’s reference to gay rights, believed to be a first for a presidential inaugural address.


“Our journey is not complete until our gay brothers and sisters are treated like anyone else under the law,” he said. “For if we are truly created equal, then surely the love we commit to one another must be equal as well.”


The president also made a forceful statement in support of comprehensive immigration reform, a campaign pledge from 2008 that remains unfulfilled. Obama has repeatedly pledged to make it one of his top legislative priorities this year.


“Our journey is not complete until we find a better way to welcome the striving, hopeful immigrants who still see America as a land of opportunity; until bright young students and engineers are enlisted in our workforce rather than expelled from our country,” he said.

2:05 p.m. – Obama’s Inaugural Declaration: ‘Our Time’ for Changing Nation


ap over view inauguration obama podium thg 130121 wblog LIVE UPDATES: Inauguration Day 2013

Analysis by ABC’s Rick Klein:


President Obama used a brief pause in the partisan warfare that’s scarred his time in office to return to the ideals of the Declaration of Independence, with his own declaration of urgency and a call to action that reflects shared sacrifice and responsibility.


This was no centrist conciliator. It was the speech of a committed, unapologetic progressive, an Obama doctrine for domestic policy that included concrete commitments in areas he made little progress on over his first four years. Above all, he was speaking to a changing America – the nation that propelled him to a second term, and whose voices he will need to channel to be effective over the next four years.


“My fellow Americans, we are made for this moment, and we will seize it – so long as we seize it together,” the president declared.

1:30 p.m. – More on Inaugural Poet Richard Blanco


Univision’s Jordan Fabian reports:


There has not been another inaugural poet like Richard Blanco.


Out of the five people selected to read an original poem at a presidential inauguration, the 44-year-old Blanco is the first Latino, first gay man, and youngest person to serve the role. The presidential inaugural committee officially announced the choice of Blanco, the son of Cuban exiles, last Wednesday.


Read more from Fabian here.


Blanco wrote the poem he read, called “One Today,” in the past 11 days. It included several references to America’s workers, including the following:


One sky: since the Appalachians and Sierras claimed
their majesty, and the Mississippi and Colorado worked
their way to the sea. Thank the work of our hands:
weaving steel into bridges, finishing one more report
for the boss on time, stitching another wound
or uniform, the first brush stroke on a portrait,
or the last floor on the Freedom Tower
jutting into a sky that yields to our resilience.

1:24 p.m. – Sen. McCaskill Calls Out SCOTUS Hats





1:24 p.m. – Terry Moran: Inauguration Fits ‘Next America’


In response to remarks about Obama’s reference to gay marriage, Nightline’s Terry Moran analyzes the firsts of this inauguration:


Has Spanish been spoken before? Has there ever been a bigger crowd for a second inaugural?


To me, Obama’s speech, this crowd, the whole program, seemed deliberately designed to confirm the “next America”–younger, more diverse, more non-native, socially liberal–as the source of authority, even legitimacy in the nation going forward.


That’s what the election was really about, deep down. And the feeling out here seems more than the usual inaugural victory lap of the party in power. It seems cultural–and historic. It’s their moment. And so is tomorrow–not in a partisan sense. In a factual one.

12:46 p.m. – Timing Is Everything: Chris Christie Makes Announcements Minutes Before Obama’s Speech


ABC News’ Michael Falcone reports:


During the very same hour of President Obama’s second inauguration, New Jersey Gov. Chris Christie, who is often mentioned as a potential 2016 Republican presidential contender, sent out two separate announcements.


The first from his gubernatorial campaign: “Governor Chris Christie will be visiting the Hilton Newark Airport on Tuesday morning to accept the second major endorsement of his campaign.” (The campaign did not provide information about who will be endorsing him). And the second, a statement commemorating Dr. Martin Luther King, Jr. Day. (Christie, who praised President Obama’s efforts in the wake of Hurricane Sandy, which devastated portions of coastal New Jersey, did not mention the president’s inauguration):


“Dr. King was the paradigm of strength in triumphing over adversity and racial injustice to achieve what seemed impossible to so many for so long. His legacy stands as an eternal reminder of his sacrifice and the progress he achieved and which we are obliged to protect for every citizen of our state and nation. I join New Jerseyans in honoring Dr. King’s life and work and his uncompromising commitment to peacefully working toward freedom and equality for all Americans,” Christie said in the statement.

12:09 p.m. – Obama Gives Shout Out to Same-Sex Couples in Inaugural Address


In his inaugural address today, President Obama called for treating same-sex couples equal under the law. ABC News’ Arlette Saenz reports:


Of the group of 215 members in the Lesbian and Gay Band Association marching in the inaugural parade, four couples are legally married.


Leslie Becker and Lindsay Famula of Hackensack, N.J., met when Famula joined the band in 2006, and the two women, who are both percussionists, were married in May.


“It’s validation. The fact that we have been denied this right for so long when really all we want to do is be seen in the government as a couple means a lot,” Becker said. “‘Don’t ask, don’t tell’ was repealed. We’re making big advancements in civil rights for gay couples, and it means a big deal to be one of the few married couples to march in this parade.”


New Jersey has allowed civil unions since 2006, but New Jersey Gov. Chris Christie vetoed a same-sex marriage bill in February.


Becker played at President Bill Clinton’s inauguration in 1997, but the LGBA only played on the side of the parade. During President Obama’s first inauguration in 2009, the LGBA, including Becker, marched in the actual parade.

No word from Mitt Romney, but his running mate, Rep. Paul Ryan sent out a congrats to President Obama.




Ryan posted a longer congratulations on his Facebook page.


I congratulate President Obama on his inauguration, and I join the country in celebrating this American tradition.


The president and I were political opponents. We had strong disagreements over the direction of the country—as we still do now. But today, we put those disagreements aside. Today, we remember what we share in common.


We serve the same country, one that is still in need of repair—and is still the freest on earth. We serve alongside men and women from both parties, who govern in good faith and good will. Finally, we serve the same people, who have honored us with their charge.


We may disagree on matters of policy. But today we remember why we take those matters so seriously—because we seek the public good. It’s our highest duty—one that we share—and one for which we’re grateful.


I’m happy to mark this historic occasion—for the president and for the country. And I look forward to tackling the big challenges ahead.

11:20 a.m. – A Look Back at Obama’s First Inaugural Address


ABC’s Elizabeth Hartfield reports:


As Obama’s prepares to give his second inaugural address, a look back at the first: Obama’s speech in 2009 ran 2,395 words.


According to a handy word count breakdown from the Wall Street Journal, Obama used the word “people” eight times, the word “God” five times, and the word “government” four times. We can expect that those words will pop up again in today’s speech, as the president is expected to talk about unity and finding common ground among our nation’s leaders.


A word he only uttered once in 2009, that we might expect him to bring up again more this time- “war” – as the president looks back on the drawdown of America’s military presence in Iraq, and ahead to the drawdown in Afghanistan.


Today’s speech is expected to be shorter than his speech four years ago – but by how much will remain to be seen. The high bar of second inauguration speeches is Abraham Lincoln’s address in 1965- where he managed to say a lot, in just a few words- 698 to be exact.

11:16 a.m. – Obama Enters Arena


President Obama has entered the Capitol. Vice President Joe Biden and House Minority Leader Nancy Pelosi are close behind.


ABC’s Michael Falcone points out President Obama will be getting down to business shortly after he delivers his second inaugural address, officially submitting the names of his nominees for the posts of CIA Director, Secretary of Defense, Secretary of State and Secretary of the Treasury, according to a White House official.


Today, at the Capitol the President will be signing:


1. A Proclamation to commemorate the inauguration titled, “National Day of Hope and Resolve, 2013.”
2. Four Nominations:
a. John Owen Brennan to be Director of the CIA
b. Charles Timothy Hagel to be Secretary of Defense
c. John Forbes Kerry to be Secretary of State
d. Jacob J. Lew to be Secretary of the Treasury


ABC’s Devin Dwyer notes that four years ago, Obama signed a similar proclamation and nominations to the Senate. This occurs in the President’s Room, just off the Senate chamber, immediately following the address.

A large Bible being carried in is attracting some attention for its size. The Bible belongs to the Biden family, and it’s the one Vice President Joe Biden will use to swear his oath of office, as he did four years ago.


The 120-year-old book has a Celtic cross on the front and has been passed down through the Biden clan. It is 5 inches thick, according to the Presidential Inaugural Committee.


Biden also used it Sunday in his private swearing-in ceremony at the Naval Observatory.

11:04 a.m. – Powell Slams GOP’s ‘Idiot Presentations’


ABC’s Michael Falcone reports:


In an interview with ABC’s Diane Sawyer and George Stephanopoulos during ABC’s special inauguration day coverage this morning, former Secretary of State Colin Powell lashed out at people in the Republican Party who spent the last four years spreading “birther nonsense” and other “things that demonize the president,” calling on GOP leaders to denounce such talk — publicly.


“Republicans have to stop buying into things that demonize the president. I mean, why aren’t Republican leaders shouting out about all this birther nonsense and all these other things? They should speak out. This is the kind of intolerance that I’ve been talking about where these idiot presentations continue to be made and you don’t see the senior leadership of the party say, ‘No, that’s wrong.’ In fact, sometimes by not speaking out, they’re encouraging it. And the base keeps buying the stuff.


“And it’s killing the base of the party. I mean, 26 percent favorability rating for the party right now. It ought to be telling them something. So, instead of attacking me or whoever speaks like I do, look in the mirror and realize, ‘How are we going to win the next election?”

ABC’s Joanna Stern reports:


Nope, it’s not inaugration. Not inaguration either. Inaugiration? Not correct. And it’s definitely not innoguration or anauguration.


Inauguration. That’s the correct spelling of the word for that big event today, at which, you know, the president officially becomes the president again.


But don’t be embarrassed if you spelled it incorrectly. It turns out it’s a pretty popular thing to do.


Over 2,500 people have tweeted about the “inaguration,” according to Topsy, which tracks tweets on Twitter. Topsy says 866 of those tweets have been in the last 30 days. “Inaugration” has been used in over 700 tweets.

ABC’s Chris Good reports on the best and worst inaugural speeches of all time:


Inaugural addresses, it is said, are usually not very good. Most have been long forgotten, and historians themselves point to few as memorable.


It’s not entirely clear why, but the moment might have something to do with it. Book-ending divisive national campaigns, inaugural addresses offer token unity sentiments, hopefulness but not always specific hopes, and even some good ones sound myopic.


“Most inaugural addresses are not remembered,” said Princeton University professor and noted presidential historian Eric Foner. “Grover Cleveland? I have no idea what he said in his.”


“I have actually read every single inaugural, and it was a really boring experience,” said Robert Lehrman, a former speechwriter for vice president Al Gore, who now teaches the craft at American University in Washington. “Most of the speeches are terrible. Even the ones we remember, I don’t think there is any reporter working anywhere that couldn’t write language as crisp or concrete as the majority of them.”

Inaugural addresses are an opportunity for presidents on the nation’s front lawn – a place that Americans come to in turns inaugurate their leaders, protest their government and mourn their dead – to place a marker for their legacy.


There have been some weighty and remarkable things said as presidents took the oath of office looking down on the Mall and also, from nearby, as other Americans have looked up and let their voices be heard at gatherings as varied as the March on Washington and the Promise Keepers.


What can Barack Obama say, come Monday, as he begins a second term with lower expectations and less inspiration, to place himself on this list of great American words?

Quadruple DNA helix discovered in human cells








































Sixty years after James Watson and Francis Crick established that DNA forms a double helix, a quadruple-stranded DNA helix has turned up.













Quadruple helices that intertwine four, rather than two, DNA strands had been made in the laboratory, but were regarded as curiosities as there was no evidence that they existed in nature. Now, they have been identified in a range of human cancer cells.












The four-stranded packages of DNA, dubbed G-quadruplexes, are formed by the interaction of four guanine bases that together form a square. They appear to be transitory structures, and were most abundant when cells were poised to divide. They appeared in the core of chromosomes and also in telomeres, the caps on the tips of chromosomes that protect them from damage.












Because cancer cells divide so rapidly, and often have defects in their telomeres, the quadruple helix might be a feature unique to cancer cells. If so, any treatments that target them will not harm healthy cells.












"I hope our discovery challenges the dogma that we really understand DNA structure because Watson and Crick solved it in 1953," says Shankar Balasubramanian of the University of Cambridge, UK.











Tagged with antibodies













Balasubramanian's team identified the four-stranded structures in cancer cells with the help of an antibody that attaches exclusively to G-quadruplexes. To stop them from unravelling into the ordinary DNA, they exposed the cells to pyridostatin, a molecule that traps quadruple helices wherever they form.












This enabled the researchers to count how many formed at each stage of cell multiplication. The G-quadruplexes were most abundant in the "S-phase" – when cells replicate their DNA just prior to dividing.












"I expect they will also exist in normal cells, but I predict that there will be differences with cancer cells," says Balasubramanian. His hunch is that the G-quadruplexes are triggered into action by chaotic genomic mutations and reorganisations typical of cancerous or precancerous cells.












"This research further highlights the potential for exploiting these unusual DNA structures to beat cancer, and the next part of this is to figure out how to target them in tumour cells," says Julie Sharp of Cancer Research UK, which funded the research.












Another important question that Balasubramanian's and other teams will try to answer is whether G-quadruplexes play a role in embryo development, and whether such a role is mistakenly reactivated in cancer cells. "We plan to find out whether the quaduplexes are a natural nuisance, or there by design," he says.

Football: Madrid hand Valencia five-goal thrashing






MADRID: Real Madrid put their dismal first half of the season behind them as they tore Valencia apart for the first 45 minutes to win 5-0 and ease the pressure on coach Jose Mourinho.

Cristiano Ronaldo and Angel Di Maria both hit braces and Gonzalo Higuain was also on target in a first-half goal romp.

But there is still little hope of them retaining their title as they trail Barcelona by 15 points despite the Catalan side losing 3-2 against Real Sociedad on Saturday, their bitter rivals' first league defeat of the season.

They are also seven points off neighbours Atletico Madrid who beat Levante 2-0 earlier Sunday.

Madrid arrived at the Mestalla having beaten Valencia 2-0 in a stormy Spanish Cup quarter-final first leg tie in mid-week and Mourinho decided against resting players ahead of the second leg on Wednesday.

There has been plenty of tension in the Madrid camp following their poor form but there were no repercussions from an argument between Mourinho and Ronaldo after the first leg of the cup.

Furthermore, Iker Casillas was preferred in goal to Adan Garrido who had controversially replaced the Spain international before being suspended.

Still they had important absentees at the back with Pepe, Sergio Ramos and Marcelo all missing and they faced a rejuvenated Valencia side under Ernesto Valverde who had won their previous three league games.

After a cagey opening spell Madrid were suddenly presented with a gift for Higuain which he failed to take advantage of in front of goal.

He was left unmarked but side-footed an Alvaro Arbeloa cross wide from six yards.

Higuain was given the chance to make amends a minute later and this time made no mistake. Again it was a case of poor defending as Di Maria scampered clear and set up Higuain who slotted into the corner.

Valencia attempted to respond but they fell apart midway through the first half as their defence was once again exposed.

Keeper Diego Alves twice denied Sami Khedira and Raphael Varane headed wide from a corner before Di Maria got the second.

Ronaldo teased makeshift right-back Ricardo Costa, standing in for Joao Pereira, and crossed for the Argentine to tuck the ball home from close range.

Valencia were in disarray at the back and Ronaldo split them open again as he burst into the left of the area and beat Alves at his near post.

Ronaldo got his second after 41 minutes when he cracked in an Ozil pass from 12 yard and then Ozil was again the provider as he put Di Maria clear for the fifth still before half-time.

Valencia showed character to come back at Madrid after the restart with Pablo Piatti hitting the crossbar and Adil Rami had a header cleared off the line by Fabio Coentrao but Madrid remained organised and managed to keep a clean sheet.

Atletico Madrid equalled their best ever winning streak at home in La Liga in a memorable season for the club with their win over Levante.

Goals from Adrian Lopez and Jorge Resurrecion 'Koke' saw Atletico win their 12th straight league game at the Calderon and match the club record dating back to a run between the 1939-40 and 1940-41 seasons.

Elsewhere on Sunday, Osasuna beat Deportivo La Coruna 2-1 and Valladolid won 2-0 against Zaragoza.

Schmidt, daughter open up about trip to North Korea



Google's Eric Schmidt (right) arrives in North Korea on January 7 with former New Mexico Gov. Bill Richardson.



(Credit:
CBS News/Screenshot by CNET)



Google's Eric Schmidt is back from his much-publicized trip to North Korea, and he's got a few details to share about his humanitarian mission.


The search giant's executive chairman had already revealed some of the reasoning behind his trip to reporters during a briefing a week and a half ago at the Beijing airport, saying that his private delegation urged North Korean officials to open up global Internet access if they wanted to strengthen their economy. The delegation was led by former New Mexico Gov. Bill Richardson, who is also a former ambassador to the U.N.


In a post last night on his Google+ page, Schmidt opened up more about his thoughts on Internet access in the country, explaining that North Korea's decision to essentially isolate itself from the global Net is going to "make it harder for them to catch up economically."


He noted that while Internet access is possible for government officials and the military and while there is a private intranet set up for universities, the general public does not have access to the Internet unless someone is watching them.



Furthermore, he said that it was obvious that the country's technology is limited. "There is a 3G network that is a joint venture with an Egyptian company called Orascom. It is a 2100 Megahertz SMS-based technology network, that does not, for example, allow users to have a data connection and use smart phones," he wrote.




A separate blog post written by Schmidt's daughter Sophie, who accompanied him on the trip, included even more details of their visit, along with a series of photos. She described the country as "very, very cold" and "very, very strange."



"Nothing I'd read or heard beforehand really prepared me for what we saw," she wrote.


The delegation apparently visited the Palace of the Sun, Kim Il Sung's former office and now the national mausoleum where Kim Il Sung's and Kim Jong Il's bodies lie in state, as well as the Kim II Sung University e-Library, which she described eerily as a room of 90 desks, all manned, with just one problem: "No one was actually doing anything. A few scrolled or clicked, but the rest just stared."


Some other interesting tidbits from her post:

  • We left our phones and laptops behind in China, since we were warned they'd be confiscated in NK, and probably infected with lord knows what malware.
  • Our trip was a mixture of highly staged encounters, tightly-orchestrated viewings and what seemed like genuine human moments. We had zero interactions with non-state-approved North Koreans and were never far from our two minders (2, so one can mind the other).
  • Ordinary North Koreans live in a near-total information bubble, without any true frame of reference.
  • We were told well ahead of time to assume that everything was bugged: phones,
    cars, rooms, meetings, restaurants and who knows what else.
  • This is a country in a permanent revolutionary state, and everything you see reflects that dug-in, determined, fiercely independent quality.
  • Their mobile network, Koryolink, has between 1-2 million subscribers. No data service, but international calls were possible on the phones we rented. Realistically, even basic service is prohibitively expensive, much like every other consumption good (fuel, cars, etc.).
  • North Korea has a national intranet, a walled garden of scrubbed content taken from the real Internet. Our understanding is that some university students have access to this.


The State Department had frowned upon the group's visit to the country, saying that the timing wasn't right. A department spokeswoman cited recent missile launches by North Korea as a reason for discouraging the mission.

Attack at Algeria Gas Plant Heralds New Risks for Energy Development



The siege by Islamic militants at a remote Sahara desert natural gas plant in Algeria this week signaled heightened dangers in the region for international oil companies, at a time when they have been expanding operations in Africa as one of the world's last energy frontiers. (See related story: "Pictures: Four New Offshore Drilling Frontiers.")


As BP, Norway's Statoil, Italy's Eni, and other companies evacuated personnel from Algeria, it was not immediately clear how widely the peril would spread in the wake of the hostage-taking at the sprawling In Amenas gas complex near the Libyan border.



A map of disputed islands in the East and South China Seas.

Map by National Geographic



Algeria, the fourth-largest crude oil producer on the continent and a major exporter of natural gas and refined fuels, may not have been viewed as the most hospitable climate for foreign energy companies, but that was due to unfavorable financial terms, bureaucracy, and corruption. The energy facilities themselves appeared to be safe, with multiple layers of security provided both by the companies and by government forces, several experts said. (See related photos: "Oil States: Are They Stable? Why It Matters.")


"It is particularly striking not only because it hasn't happened before, but because it happened in Algeria, one of the stronger states in the region," says Hanan Amin-Salem, a senior manager at the industry consulting firm PFC Energy, who specializes in country risk. She noted that in the long civil war that gripped the country throughout the 1990s, there had never been an attack on Algeria's energy complex. But now, hazard has spread from weak surrounding states, as the assault on In Amenas was carried out in an apparent retaliation for a move by French forces against the Islamists who had taken over Timbuktu and other towns in neighboring Mali. (See related story: "Timbuktu Falls.")


"What you're really seeing is an intensification of the fundamental problem of weak states, and empowerment of heavily armed groups that are really well motivated and want to pursue a set of aims," said Amin-Salem. In PFC Energy's view, she says, risk has increased in Mauritania, Chad, and Niger—indeed, throughout Sahel, the belt that bisects North Africa, separating the Sahara in the north from the tropical forests further south.


On Thursday, the London-based corporate consulting firm Exclusive Analysis, which was recently acquired by the global consultancy IHS, sent an alert to clients warning that oil and gas facilities near the Libyan and Mauritanian borders and in Mauritania's Hodh Ech Chargui province were at "high risk" of attack by jihadis.


"A Hot Place to Drill"


The attack at In Amenas comes at a time of unprecedented growth for the oil industry in Africa. (See related gallery: "Pictures: The Year's Most Overlooked Energy Stories.") Forecasters expect that oil output throughout Africa will double by 2025, says Amy Myers Jaffe, executive director of the energy and sustainability program at the University of California, Davis, who has counted 20 rounds of bidding for new exploration at sites in Africa's six largest oil-producing states.


Oil and natural gas are a large part of the Algerian economy, accounting for 60 percent of government budget revenues, more than a third of GDP and more than 97 percent of its export earnings. But the nation's resources are seen as largely undeveloped, and Algeria has tried to attract new investment. Over the past year, the government has sought to reform the law to boost foreign companies' interests in their investments, although those efforts have foundered.


Technology has been one of the factors driving the opening up of Africa to deeper energy exploration. Offshore and deepwater drilling success in the Gulf of Mexico and Brazil led to prospecting now under way offshore in Ghana, Mozambique, and elsewhere. (See related story: "New Oil—And a Huge Challenge—for Ghana.") Jaffe says the Houston-based company Anadarko Petroleum has sought to transfer its success in "subsalt seismic" exploration technology, surveying reserves hidden beneath the hard salt layer at the bottom of the sea, to the equally challenging seismic exploration beneath the sands of the Sahara in Algeria, where it now has three oil and gas operations.


Africa also is seen as one of the few remaining oil-rich regions of the world where foreign oil companies can obtain production-sharing agreements with governments, contracts that allow them a share of the revenue from the barrels they produce, instead of more limited service contracts for work performed.


"You now have the technology to tap the resources more effectively, and the fiscal terms are going to be more attractive than elsewhere—you put these things together and it's been a hot place to drill," says Jaffe, who doesn't see the energy industry's interest in Africa waning, despite the increased terrorism risk. "What I think will happen in some of these countries is that the companies are going to reveal new securities systems and procedures they have to keep workers safe," she says. "I don't think they will abandon these countries."

Sasha's View: 'Good Job, Daddy. You Didn't Mess Up'













President Barack Obama and Vice President Joe Biden today officially embarked on their second term, taking the Constitutionally mandated oath of office in two separate private ceremonies inside their homes.


Shortly before noon in the Blue Room of the White House, Obama raised his right hand, with his left on a family Bible, reciting the oath administrated by Chief Justice John Roberts. He was surrounded by immediate family members, including first lady Michelle Obama and daughters, Malia and Sasha.


As he hugged his wife and daughters, Sasha said, "Good job, Daddy."


"I did it," he said.


"You didn't mess up," she answered.


Biden was sworn in earlier today by Justice Sonia Sotomayor, the first Hispanic to administer a presidential oath, in a ceremony at his official residence at the U.S. Naval Observatory. He was joined by more than 120 guests, including cabinet members, extended family and his wife, Dr. Jill Biden.


Because Jan. 20 -- the official date for a new presidential term -- falls on a Sunday this year, organizers delayed by one day the traditional public inauguration ceremony and parade down Pennsylvania Avenue.








Vice President Joe Biden Sworn in for 2nd Term Watch Video











President Obama's 2nd Inauguration: Hundreds of Thousands to Attend Watch Video





Obama and Biden will each repeat the oath on Monday on the west front of the Capitol, surrounded by hundreds of dignitaries and members of Congress. An estimated 800,000 people are expected to gather on the National Mall to witness the moment and inaugural parade to follow.


The dual ceremonies in 2013 means Obama will become the second president in U.S. history to take the presidential oath four times. He was sworn in twice in 2008 out of an abundance of caution after Roberts flubbed the oath of office during the public administration. This year Roberts read from a script.


Franklin Roosevelt was also sworn in four times but, unlike Obama, he was elected four times.


This year will mark the seventh time a president has taken the oath on a Sunday and then again on Monday for ceremonial purposes. Reagan last took the oath on a Sunday in 1985.


Both Obama and Biden took the oath using a special family Bible. Obama used a text that belonged to Michelle Obama's grandmother LaVaughn Delores Robinson. Biden placed his hand on a 120-year-old book with a Celtic cross on the cover that has been passed down through Biden clan.


The official inaugural activities today also included moments of prayer and remembrance that marked the solemnity of the day.


Obama and Biden met at Arlington National Cemetery for a brief morning ceremony to place a wreath on the Tomb of the Unknowns, honoring military service members who served and sacrificed. The men stood shoulder to shoulder, bowing their heads as a bugler played "Taps."


Biden, who is Catholic, began the day with a private family mass at his residence. The president and first family attended church services at Metropolitan African Methodist Episcopal Church, a historically black church and site of two pre-inaugural prayer services for former President Bill Clinton and Vice President Al Gore and their families.


The Obamas and Bidens plan to participate in a church service on Monday morning at St. John's Episcopal, across Lafayette Park from the White House. They will also attend a National Prayer Service on Tuesday at the National Cathedral.


Later on Sunday evening, the newly-inaugurated leaders will attend a candlelight reception at the National Building Museum. The president and vice president are expected to deliver brief remarks to their supporters.

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?"

Football: Pogba at double for Juve as Palermo hold Lazio






MILAN: French teenager Paul Pogba scored a sensational brace to inspire depleted Juventus to a 4-0 rout of Udinese which helped the Serie A champions extend their lead over Lazio on Saturday.

Juve started their 21st match of the campaign with a three-point lead on both Napoli and Lazio but missing key midfielders Andrea Pirlo, Claudio Marchisio and Arturo Vidal due to recent injuries.

After Lazio had to settle for a share of the points in a 2-2 draw at strugglers Palermo, Juve took full advantage.

The champions now have a five-point lead over Lazio, who sit second on 43 points, and will be hoping Napoli, third on 42, find similar trouble Sunday in their away game against Fiorentina.

Pogba, signed in the off-season on a free transfer from Manchester United, had already scored two sensational goals earlier this season.

And the 19-year-old broke the deadlock near the end of a frustrating first half for the hosts by unleashing a 30-metre screamer which hit the crossbar before beating Daniele Padelli in the Udinese goal.

Juventus were struggling to build on their lead in the early stages of the second half when Udinese were unlucky not to score on the counter.

But again Pogba came to the rescue, this time with a long-range daisy-cutter which slotted into Padelli's bottom corner to give Juve a 2-0 lead.

Six minutes later Juve striker Mirko Vucinic made it 3-0 when Padelli parried the Montenegrin's close-range effort over his own body and into the net.

Udinese threatened through top striker Antonio Di Natale, who saw a snapshot shave the top of the crossbar.

However the former Italy striker appeared to be showing the effects of recent flu-like symptoms, which meant he only appeared early in the second half.

With 10 minutes to play, second half substitute Alessandro Matri made it 4-0 for the hosts when he latched on to a Vucinic through ball to nutmeg Padelli.

Despite missing Miroslav Klose, Abdoullay Konko and Ederson, Lazio had hoped to secure a win that would have kept them three points behind Antonio Conte's league leaders.

But after Vladimir Petkovic's side were stunned by two goals in less than two minutes the visitors were forced to launch a late fighback to grab a share of the points

Sergio Floccari gave Lazio a 10th minute lead when he headed Cristian Ledesma's cross over the static Samir Ujkani in the Palermo goal, only for Arevalo Rios (70) and Paulo Dybala (71) to give the hosts a shock lead.

It took a penalty from Brazilian Hernanes, after Floccari had been fouled in the box, for Lazio to draw level with six minutes left to play.
