US seeks quick vote on N.Korea sanctions resolution






UNITED NATIONS: The United States on Monday circulated a resolution on sanctions against North Korea to other UN Security Council members and hopes for a vote within days, diplomats said.

The resolution condemns North Korea for staging a ballistic missile test in December and follows weeks of negotiations between the United States and China, diplomats said.

"The United States circulated the draft text today after getting agreement from China. The vote could be held Wednesday," a diplomat from the 15-member council told AFP.

China, the unpredictable North's closest ally, has opposed establishing new sanctions against Pyongyang for the December 12 rocket launch. But it has agreed to expand existing sanctions and to the formal resolution instead of a lower-level statement, diplomats said.

The United States, supported by Japan and South Korea, had wanted tough new sanctions for the rocket launch, which was virtually unanimously condemned by the international community.

North Korea already faces UN sanctions for its nuclear tests in 2006 and 2009.

Under US-China agreement, new North Korean companies and entities could be added to the sanctions list, diplomats said. Individuals could be named for sanctions for the first time, they added.

The United States and China want a resolution passed before South Korea takes over the presidency of the Security Council in February, envoys said.

US and Chinese diplomats made no immediate comment on the resolution.

The Security Council agreed on a presidential statement, with lower standing than a binding resolution, after North Korea staged a failed rocket launch in April last year.

That had already called for a tightening of existing UN sanctions.

Clouds ruin GeoEye's satellite image of inauguration

Aw, shucks: imaging company GeoEye could not capture a super high-resolution image of Obama's inauguration today from space.


Using its GeoEye-1 and IKONOS satellites positioned 423 miles above the Earth, the company tried and failed -- due to clouds -- on two separate attempts to capture the image of the inauguration, a GeoEye representative told CNET. GeoEye planned to release an interactive map of the ceremony with a built-in zoom and a slider that would have let the user compare this year's image to the one captured four years ago. Feel free to zoom around in the 2009 Inauguration image embedded below.





For those who just can't accept the bad news from GeoEye, Canadian astronaut Chris Hadfield snapped an image (seen above) of an illuminated Washington, D.C. several days before the inauguration. The day before the event, astronauts aboard the International Space Station captured a picture (seen below) of the greater National Mall area.


"This detailed view shows the Potomac River and its bridges at left, with National Mall at the center, stretching eastward from the Lincoln Memorial to the Washington Monument toward the Capitol building, where the inaugural ceremony will be held," NASA officials said in a statement.


In 2009, GeoEye released a satellite image of Obama's first Inauguration that clearly revealed the hundreds of thousands of people who attended the landmark event, which takes place on the West Front of the U.S. Capitol Building in Washington, D.C.

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."

Obama's 2nd Term: Who's Time Is 'Our Time'?


Jan 21, 2013 12:50pm







gty barack obama inauguration 2 ll 130121 wblog Obamas Inaugural Declaration: Our Time for Changing Nation

Jewel Samad/AFP/Getty Images

ANALYSIS By 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.


That word “together” appeared seven times in the president’s speech. He used the phrase, “we, the people” five times. Notably, the president said “our time” five times. It was a clear signal that Obama is not satisfied with the frustrations that marked his first term, and that he is cognizant of his opportunity at this moment.


And he sees those opportunities mainly to his left. Obama made a firm commitment to pursue climate-change legislation, in addition to immigration reform and gun control. In an era of budget-cutting, he delivered a rousing endorsement of the social safety net, including Medicare and Social Security.


Obama cited the civil-rights movement and listed Stonewall – the 1960s demonstrations over a police raid of a New York City gay bar that galvanized the gay-rights movement – alongside Seneca Falls and Selma. He also promised equality for “our gay brothers and sisters,” apparently becoming the first president to use the word “gay” in an inaugural address.


Obama’s defining challenge as president has been to deliver on the hope and promise he rode into office on in 2008. He may never hope to fulfill the expectations that surrounded his elevation. But speaking to the largest crowd he’s likely to ever appear before again, the president sounded both more optimistic and more committed to progress on his priorities than anything in our current political system would suggest is warranted.


“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,” the president said.


For a president whose very inauguration speaks to the promise of America, but whose first term ended with so much frustration, it was a return to his roots. President Obama is cognizant of his role in history, though clearly not content with leaving it at that.

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: Sneijder signs for Galatasaray for 7.5m euros






ROME: Inter Milan's Dutch midfielder Wesley Sneijder signed for Turkish side Galatasaray on Sunday for a fee believed to be in the region of 7.5 million euros, the Istanbul side announced.

Playmaker Sneijder penned a three and a half-year deal which will keep him at Galatasaray until 2016 as the drawn-out transfer saga was finally completed.

The Gazzetta dello Sport reported that the player would earn around five million euros a season.

Sneijder was a key figure in the treble winning season under Jose Mourinho in 2010 when they won the Italian title, the Italian Cup as well as their first Champions League trophy since 1965.

But he fell out with the club this season after Inter asked him to accept a reduction in salary and extend his contract by one year to 2016 without a change in total salary.

Sneijder's Romanian teammate Cristian Chivu said he wanted to see the Dutchman succeed in Turkey.

"He's my friend and team-mate, I wish him all the best in the world. I'll speak to him on the phone," he said.

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.

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?"
