Obama hands drone war guidelines to US lawmakers






WASHINGTON: President Barack Obama will hand lawmakers classified documents outlining the legal justification for drone strikes which kill US citizens abroad who are conspiring with Al-Qaeda.

An administration official disclosed the move on Wednesday on the eve of a Senate hearing on Obama's nomination of his top White House anti-terror advisor John Brennan to lead the Central Intelligence Agency in his second term.

Some senators had warned Brennan's confirmation could be in doubt if the administration did not share more information on the legal and constitutional grounding for the US government killing its own citizens.

The disclosure also comes after NBC News published an unclassified Justice Department white paper covering similar ground, reigniting the debate about the killing of estranged Americans who switched sides in the "War on Terror."

"Today, as part of the president's ongoing commitment to consult with Congress on national security matters, the president directed the Department of Justice to provide the congressional intelligence committees access to classified Office of Legal Counsel advice related to the subject of the Department of Justice White Paper," an administration official said.

Obama aides insist killing Al-Qaeda suspects, some of them US citizens, in places like Pakistan or Yemen, complies with US law and the Constitution, even when no intelligence links the targets to specific attack plots.

"We conduct those strikes because they are necessary to mitigate ongoing actual threats, to stop plots, to prevent future attacks and, again, save American lives," said White House spokesman Jay Carney said Tuesday.

"These strikes are legal, they are ethical, and they are wise."

Among the most controversial of the attacks were the September 2011 killings in Yemen of Anwar al-Awlaki and Samir Khan, which stoked concern because the pair were both US citizens who had never been charged with a crime.

It's been said that Ubuntu's open-source operating system would be available on smartphones by the end of the year, and now it's confirmed that consumers can get their hands on such devices in October.

Ubuntu is made by Canonical, and according to the Wall Street Journal, the founder and CEO of Canonical Mark Shuttleworth said that Ubuntu OS smartphones will be available in October and app developers will get access to the OS later this month.

It's not yet clear which smartphones will run Ubuntu's OS, but app developers will be able to work with the OS on Samsung's Galaxy Nexus.

Ubuntu OS is long a favorite open-source platform for computing. And now, as it gets ready for a smaller screen, the OS will use the same drivers as
Android smartphones and will also be able to run on entry-level smartphones.

Ubuntu for phones will use native apps, which means that developers can create a single app for both the desktop and the PC. This will let users easily move between devices. The OS also favors swiping gestures to reveal navigation strips and overview pages.

According to the Wall Street Journal, several carriers are interested in the smartphone, but it's still unclear which ones Canonical will partner with.

Humans Swap DNA More Readily Than They Swap Stories

Jane J. Lee


Once upon a time, someone in 14th-century Europe told a tale of two girls—a kind one who was rewarded for her manners and willingness to work hard, and an unkind girl who was punished for her greed and selfishness.

This version was part of a long line of variations that eventually spread throughout Europe, finding their way into the Brothers Grimm fairytales as Frau Holle, and even into Shakespeare's The Merchant of Venice. (Watch a video of the Frau Holle fairytale.)

In a new study, evolutionary psychologist Quentin Atkinson is using the popular tale of the kind and unkind girls to study how human culture differs within and between groups, and how easily the story moved from one group to another.

Atkinson, of the University of Auckland in New Zealand, and his co-authors employed tools normally used to study genetic variation within a species, such as people, to look at variations in this folktale throughout Europe.

The researchers found that there were significant differences in the folktale between ethnolinguistic groups—or groups bound together by language and ethnicity. From this, the scientists concluded that it's much harder for cultural information to move between groups than it is for genes.

The study, published February 5 in Proceedings of the Royal Society B, found that about 9 percent of the variation in the tale of the two girls occurred between ethnolinguistic groups. Previous studies looking at the genetic diversity across groups in Europe found levels of variation less than one percent.

For example, there's a part of the story in which the girls meet a witch who asks them to perform some chores. In different renditions of the tale, the meeting took place by a river, at the bottom of a well, or in a cave. Other versions had the girls meeting with three old men or the Virgin Mary, said Atkinson.

Conformity

Researchers have viewed human culture through the lens of genetics for decades, said Atkinson. "It's a fair comparison in the sense that it's just variation across human groups."

But unlike genes, which move into a population relatively easily and can propagate randomly, it's harder for new ideas to take hold in a group, he said. Even if a tale can bridge the "ethnolinguistic boundary," there are still forces that might work against a new cultural variation that wouldn't necessarily affect genes.

"Humans don't copy the ideas they hear randomly," Atkinson said. "We don't just choose ... the first story we hear and pass it on.

"We show what's called a conformist bias—we'll tend to aggregate across what we think everyone else in the population is doing," he explained. If someone comes along and tells a story a little differently, most likely, people will ignore those differences and tell the story like everyone else is telling it.

"That makes it more difficult for new ideas to come in," Atkinson said.

Cultural Boundaries

Atkinson and his colleagues found that if two versions of the folktale were found only six miles (ten kilometers) away from each other but came from different ethnolinguistic groups, such as the French and the Germans, then those versions were as different from each other as two versions taken from within the same group—say just the Germans—located 62 miles (100 kilometers) away from each other.

"To me, the take-home message is that cultural groups strongly constrain the flow of information, and this enables them to develop highly local cultural traditions and norms," said Mark Pagel, of the University of Reading in the U.K., who wasn't involved in the new study.

Pagel, who studies the evolution of human behavior, said by email that he views cultural groups almost like biological species. But these groups, which he calls "cultural survival vehicles," are more powerful in some ways than our genes.

That's because when immigrants from a particular cultural group move into a new one, they bring genetic diversity that, if the immigrants have children, get mixed around, changing the new population's gene pool. But the new population's culture doesn't necessarily change.

Atkinson plans to keep using the tools of the population-genetics trade to see if the patterns he found in the variations of the kind and unkind girls hold true for other folktale variants in Europe and around the world.

Humans do a lot of interesting things, Atkinson said. "[And] the most interesting things aren't coded in our DNA."

Armstrong May Testify Under Oath on Doping













Facing a federal criminal investigation and a deadline tonight to tell all under oath to anti-doping authorities or lose his last chance at reducing his lifetime sporting ban, Lance Armstrong now may cooperate.


His apparent 11th-hour about-face, according to the U.S. Anti Doping Agency (USADA), means he now might testify under oath and give full details to USADA of how he cheated for so long.


"We have been in communication with Mr. Armstrong and his representatives and we understand that he does want to be part of the solution and assist in the effort to clean up the sport of cycling," USADA CEO Travis T. Tygart said in a written statement this evening. "We have agreed to his request for an additional two weeks to work on details to hopefully allow for this to happen."


The news of Armstrong's unexpected possible cooperation came a day after ABC News reported he was in the crosshairs of federal criminal investigators. According to a high-level source, "agents are actively investigating Armstrong for obstruction, witness tampering and intimidation" for allegedly threatening people who dared tell the truth about his cheating.


The case was re-ignited by Armstrong's confession last month to Oprah Winfrey that he doped his way to all seven of his Tour de France titles, telling Winfrey he used performance-enhancing drugs throughout his career and then lied about it. He made the confession after years of vehement denials that he cheated.

If charges are ultimately filed, the consequences of "serious potential crimes" could be severe, ABC News legal analyst Dan Abrams said -- including "possible sentences up to five, 10 years."


Investigators are not concerned with the drug use, but Armstrong's behavior in trying to maintain his secret by allegedly threatening and interfering with potential witnesses.


Armstrong was previously under a separate federal investigation that reportedly looked at drug distribution, conspiracy and fraud allegations -- but that case was dropped without explanation a year ago. Sources at the time said that agents had recommended an indictment and could not understand why the case was suddenly dropped.


"There were plenty of people, even within federal law enforcement, who felt like he was getting preferential treatment," said T.J. Quinn, an investigative reporter with ESPN.


The pressures against Armstrong today are immense and include civil claims that could cost him tens of millions of dollars.


Armstrong is currently serving a lifetime ban in sport handed down by the U.S. Anti-Doping Agency, and today was the deadline he was given to cooperate under oath if he ever wanted the ban lifted.

Asian markets rebound, weaker yen boosts Tokyo






HONG KONG: Asian markets climbed Wednesday following big losses in the previous session, with Tokyo surging as the yen tumbled after Bank of Japan governor Masaaki Shirakawa said he will step down early.

Traders also took a lead from Wall Street and Europe, where encouraging economic data offset concerns over political uncertainty in Spain and Italy.

Tokyo soared more than three per cent to a 33-month high, Sydney added 0.84 per cent, Seoul gained 0.19 per cent, Hong Kong added 0.62 per cent and Shanghai was up 0.10 per cent.

Wellington was closed for a public holiday.

Japanese foreign exchange traders welcomed Shirakawa's announcement that he would step down on March 19, about three weeks before the end of his term.

It fuelled expectations that Prime Minister Shinzo Abe will likely fill the post with someone who shares his ideas on aggressive monetary easing that would see more yen pumped into the economy.

The Japanese currency tumbled in New York. By the end of trade Tuesday the dollar bought 93.61 yen and the euro was at 127.13 yen, compared with 92.28 yen and 124.67 yen earlier in the day in Tokyo.

In early Tokyo trade on Wednesday the dollar bought 93.55 yen and the euro fetched 127.06 yen.

The euro was also at $1.3581, compared with $1.3582 in New York and much stronger than the $1.3489 Tuesday in Tokyo.

Major Japanese exporters have been raising their earnings outlooks thanks to recent weakness in the yen, heartening investors.

"Global markets continue to normalise, allowing risk-on trading to resume," said SMBC Nikko Securities general manager of equities Hiroichi Nishi.

"This is partially reflected in the fall of the yen," he told Dow Jones Newswires.

Regional markets resumed their upward trend after suffering a heavy jolt on Tuesday after Spain's Prime Minister Mariano Rajoy was forced to deny corruption claims.

A surge in the polls for the party of former Italian premier Silvio Berlusconi, who has said he would roll back recent austerity measures, spooked markets ahead of an election this month.

However, encouraging data showed US services sector activity rising and the contraction in eurozone business activity decelerating.

Wall Street rebounded after diving Tuesday as the Dow sits close to record highs. The Dow ended 0.71 per cent higher, the S&P 500 climbed 1.04 per cent and the Nasdaq rose 1.29 per cent.

In Europe markets on Tuesday recovered some of the huge losses suffered in the previous session.

Oil prices fell, with New York's main contract, light sweet crude for delivery in March, shedding 12 cents to $96.52 a barrel and Brent North Sea crude for March delivery slipping a cent to $116.51.

Gold was at $1,672.11 at 0230 GMT compared with $1,678.01 late Tuesday.

Dueling disks: Apple's 128GB response to Surface Pro



Not all disk subsystems are created equal. Microsoft has opted for a speedy mSATA-based SSD for its Surface Pro.

With the 128GB iPad, Apple is obviously trying to steal thunder from Microsoft's Saturday roll out of the Surface Pro. But that doesn't mean you can equate the iPad's disk performance with the Surface Pro's.


Apple's carefully-timed release of the 128GB iPad ostensibly puts the
iPad's storage on par with Microsoft's 128GB
Surface Pro, which will go on sale Saturday.


Well, not quite.


Apple is using a flash drive optimized for power efficiency, while Microsoft's solid-state drive favors speed -- the same kind of drive used in ultrabooks. (And Apple's MacBooks, for that matter.)


"Apple is using something that's more optimized for cost/power/form factor while Microsoft is using the type of SSD you'd stick in a high-end Ultrabook or other PC," Anand Shimpi of Anandtech, told CNET.


For the Surface Pro, Microsoft went with an SSD based on the mSATA interface, according to Michael Yang, a memory and storage analyst at IHS iSuppli. And Microsoft confirmed the mSATA interface today with CNET.



That's the same interface used in ultrabooks boasting read speeds of more than 400MB per second and writes up 250MB per second.


But Yang said that it's really a combination of silicon that should give Microsoft's tablet its snappy disk performance. "The Surface Pro [has] hardware almost identical to an Ultrabook...the Core i5, 4GB of DRAM and mSATA SSD should provide users with very peppy performance with the new
Windows 8 operating system," Yang said.

And a high-performance SSD is necessary with Windows, which is designed as a multitasking OS: users typically have multiple windows open on the desktop and multiple tasks executing (e.g., encoding a video and editing a photo) at the same time. That's not the case with iOS, which is designed to run one thing at a time.

And Yang added that there are a lot of other factors that come into play, including how the operating system interacts with storage subsystem.

And, speaking of software, another key difference between the two devices has nothing to with hardware and everything to do with software. Microsoft has stated publicly that the 128GB Surface with Windows 8 Pro will ship with 83GB of available storage.

Apple's 128GB iPad, on the other hand, will undoubtedly have considerably more available storage due to the small footprint of iOS.

The Real Richard III


It's a question that actors from Laurence Olivier to Kevin Spacey have grappled with: What did Richard III, the villainous protagonist of Shakespeare's famous historical drama, really look and sound like?

In the wake of this week's announcement by the University of Leicester that archaeologists have discovered the 15th-century British king's lost skeleton beneath a parking lot, news continues to unfold that helps flesh out the real Richard III.

The Richard III Society unveiled a 3D reconstruction today of the late king's head and shoulders, based on computer analysis of his skull combined with an artist's interpretation of details from historical portraits. (Related: "Shakespeare's Coined Words Now Common Currency.")

"We received the skull data before DNA analysis confirmed that the remains were Richard III, and we treated it like a forensic case," said Caroline Wilkinson, the University of Dundee facial anthropologist who led the reconstruction project. "We were very pleasantly surprised by the results."

Though Shakespeare describes the king as an "elvish-marked, abortive, rooting hog," the reconstructed Richard has a pleasant, almost feminine face, with youthful skin and thoughtful eyes. His right shoulder is slightly higher than the left, a consequence of scoliosis, but the difference is barely visible, said Wilkinson.

"I think the whole Shakespearean view of him as being sort of monster-like was based more on his personality than his physical features," she reflected.

Look back at 125 years of National Geographic history

People are naturally fascinated by faces, especially of historical figures, said Wilkinson, who has also worked on reconstructions of J.S. Bach, the real Saint Nicholas, the poet Robert Burns, and Cleopatra's sister.

"We make judgments about people all the time from looking at their appearance," she said. "In Richard's case, up to now his image has been quite negative. This offers a new context for considering him from the point of view of his anatomical structure rather than his actions. He had quite an interesting face."

A Voice From the Past

Most people's impression of Richard's personality comes from Shakespeare's play, in which the maligned ruler utters such memorable lines as "Now is the winter of our discontent/Made glorious summer by this son of York," and "A horse! A horse! My kingdom for a horse!"

But how would the real Richard III have expressed himself? Did he have an accent? Was there any sense of personality or passion in his choice of words?

To find out more about the mysterious monarch, Philip Shaw, a historical linguist at University of Leicester's School of English, analyzed the only two known examples of Richard III's own writing. Both are postscripts on letters otherwise composed by secretaries—one in 1469, before Richard became king, and one from 1483, the first year of his brief reign.

Shaw identified a quirk of spelling that suggests that Richard may have spent time in the West Midlands, or perhaps had a tutor who hailed from there.

"I was looking to compare the way he spells things with the way his secretaries spell things, working on the assumption that he would have been schooled to a fairly high level," Shaw explained.

In the 1469 letter, Richard spells the word "will" as "wule," a variation associated with the West Midlands. But Shaw also notes that by 1483, when Richard wrote the second letter's postscript, he had changed his spelling to the more standard "wyll" (the letters 'i' and 'y' were largely interchangeable during that period of Middle English).

"That could suggest something about him brushing up over the years, or moving toward what would have been the educated standard," Shaw said, noting that the handwriting in the second example also appears a bit more polished. "One wonders what sort of practice and teaching he'd had in the interim."

Although it's hard to infer tone of voice from written letters, there is certainly emotion in the words penned by Richard III.

In the 1469 letter, the 17-year-old seeks a loan of 100 pounds from the king's undertreasurer. Although the request is clearly stated in the body of the letter, Richard adds an urgent P.S.: "I pray you that you fail me not now at this time in my great need, as you will that I show you my good lordship in that matter that you labour to me for."

That could either be a veiled threat (If you don't lend me the money, I won't do that thing you asked me to do) or friendly cajoling (Come on, I'm helping you out with something, so help me out with this loan).

"His decision to take the pen himself shows you how important that personal touch must have been in getting people to do something," Shaw said.

The second letter, written to King Richard's chancellor in 1483, also conveys a sense of urgency. He had just learned that the Duke of Buckingham—once a close ally—was leading a rebellion against him.

"He's asking for his Great Seal to be sent to him so that he can use it to give out orders to suppress the rebellion," Shaw said. "He calls the Duke 'the most untrue creature living. You get a sense of how personally let down and betrayed he feels."

Shaw said he hopes his analysis—in combination with the new facial reconstruction—will help humanize Richard III.

"He probably wasn't quite the villain that Shakespeare portrays, though I suspect he was quite ruthless," he said. "But you probably couldn't afford to be a very nice man if you wanted to survive as a king in those days."

White House: Drone Strikes on Americans 'Legal'





Feb 5, 2013 3:54pm


The White House today defended the use of targeted drone strikes against U.S. citizens abroad suspected of high-level terrorist activity, but declined to detail the criteria for ordering such an attack.


“Sometimes we use remotely piloted aircraft to conduct targeted strikes against specific al Qaeda terrorists in order to prevent attacks on the United States and to save American lives,” White House Press Secretary Jay Carney told reporters.


“We conduct those strikes because they are necessary to mitigate ongoing actual threats, to stop plots, to prevent future attacks and, again, save American lives. These strikes are legal, they are ethical, and they are wise,” he said.

U.S. Air Force


Administration lawyers found it is lawful to kill an American citizen if a “high-level” government official believes the target is an operational leader of al Qaeda who poses “an imminent threat of violent attack against the United States” and if capture is infeasible, according to a newly disclosed Justice Department document.


The 16-page white paper, first obtained by NBC News, finds there “exists no appropriate judicial forum to evaluate these constitutional considerations” and that the administration does not need to present evidence to a court before or after ordering such an attack.


“The condition that an operational leader present an ‘imminent’ threat of violent attack against the United States does not require the United States to have clear evidence that a specific attack on U.S. persons and interests will take place in the immediate future,” the document reads.


Carney repeatedly declined to discuss the details of the white paper.


“I would point you to the ample judicial precedent for the idea that someone who takes up arms against the United States in a war against the United States is an enemy and therefore could be targeted accordingly,” he told ABC News’ Jon Karl.


“[The president] takes his responsibility as commander in chief to protect the United States and its citizens very seriously. He takes the absolute necessity to conduct our war against al Qaeda and its affiliates in a way that’s consistent with the Constitution and our laws very seriously,” he said.


The white paper is believed to be a summary of the reported classified memo that outlined the legal justification for the drone attack that killed American-born radical cleric Anwar al-Awlaki in September 2011.


The American Civil Liberties Union has called the newly discovered document “profoundly disturbing.”


“It’s hard to believe that it was produced in a democracy built on a system of checks and balances. It summarizes in cold legal terms a stunning overreach of executive authority — the claimed power to declare Americans a threat and kill them far from a recognized battlefield and without any judicial involvement before or after the fact,” ACLU National Security Project director Hina Shamsi said in a written statement.


The Obama administration has carried out more than 300 CIA drown strikes in Pakistan, far more than his predecessor, President George W. Bush, according to the Bureau of Investigative Journalism.


Pressure is building from Capitol Hill for the White House to outline its legal authority to kill American citizens in counterterrorism operations.


“It is vitally important… for Congress and the American public to have a full understanding of how the executive branch interprets the limits and boundaries of this authority,” a group of eleven bipartisan Senators wrote in a letter to the president Monday, “so that Congress and the public can decide whether this authority has been properly defined, and whether the President’s power to deliberately kill American citizens is subject to appropriate limitations and safeguards.”
