Canadians protest Tunisian opposition chief's death






MONTREAL: Hundreds of people gathered late Wednesday in Montreal to express their outrage over the shooting death of Tunisian opposition leader Chokri Belaid.

The protesters, mostly youths, held candles and some wrapped themselves in Tunisian flags under bitterly cold temperatures.

The Tunisian Collective of Canada, which backed the Arab Spring movement that triggered the fall of dictator Zine El Abidine Ben Ali's regime two years ago, accused Tunisia's current government of failing to "combat corruption and criminals."

"Tunisian justice remains hostage to executive power," the group said, calling on the government to conduct a thorough investigation into Belaid's death.

Belaid, whose funeral will be on Friday after the main weekly prayers, was a populist known for his iconic smile and black moustache.

A lawyer who spoke with the working class accent of northwestern Tunisia, he defended human rights, was jailed under Ben Ali and ex-president Habib Bourguiba, and was a member of executed Iraqi dictator Saddam Hussein's defence team.

His death sparked deadly protests, attacks on offices of the ruling Islamist Ennahda party and pledges for a new government of technocrats.

Tesla rolls out remote app for Model S



Tesla Model S app

Tesla's new app will let Model S owners view their cars' charging status.

When we reviewed the Tesla Model S, we came away very impressed by the driving character and the cabin electronics, but some features, common on other high-end or electric cars, were missing. Tesla made up for one of those features by making a smartphone app available that will let Model S owners view their battery levels.


These types of apps have become common for electric
cars; Ford offers MyFord Mobile for the Focus Electric and Honda has its HondaLink EV for the Fit EV. The electric car includes a mobile data connection, which owners can use to view everything from battery status to the car's location. These apps often include features such as remotely starting or stopping charging, if the car is currently plugged in, and locking or unlocking the doors.


Tesla's app does not seem to be as expansive in its utility as some. In a blog post, the company says drivers can monitor charging, start climate control, and honk the horn. The mobile data connection means that the app will work anywhere the phone has coverage, although if the car is parked somewhere with no mobile data coverage, the app will not work.


An image of the app released by Tesla also seems to show the car's location.


Tesla demonstrated one of the virtues of the Model S in its implementation of the new app, its ability to deliver software updates to the car remotely. Past updates have covered bug fixes and the addition of voice command.

The Tesla app is available for iOS and
Android.

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."

NTSB to Challenge 787 Battery Tests













The National Transportation Safety Board will publicly question at a news conference planned for Thursday morning in Washington whether the Federal Aviation Administration and Boeing adequately tested the lithium batteries that have caught fire on Dreamliners in the U.S. and Japan, ABC News has learned exclusively from a government source.


The NTSB will say its investigation into the fire on the 787 at Boston's Logan Field showed gaps between what happened with the battery in testing and what happened with the battery confiscated by the NTSB in Boston, a source told ABC News.


The NTSB investigation followed the mid-January announcement that the FAA ordered the grounding of all Boeing 787 Dreamliner jets until their U.S. operator proved that batteries on the planes are safe.


The pre-certification test results were found to be different than what happened during NTSB investigation, the source said. The agency, charged with investigating civil aviation accidents in the U.S., is expected to question whether the Boeing tests certified by the FAA were "robust enough."


The NTSB told ABC News that its investigation is looking at the battery failure and what caused it, as well as the certification processes, emphasizing that the FAA has been "very cooperative in allowing our investigators access to the certification review that they are undertaking on their own."

Boeing 787 Dreamliner Deemed Safe Despite Mishaps Watch Video







Both the airplane maker and the FAA are responsible for the testing, the government source said.


This morning, the chairwoman of the NTSB, Deborah Hersman, told reporters at a breakfast briefing that the initial investigation into the batteries found "multiple cells where we saw uncontrolled chemical chain reaction," including short circuiting and thermal runaway, "and those features are not what we would have expected to see in a brand new battery, in a brand new airplane.


"We're evaluating assessments that were made, whether or not those assessments were accurate, whether they were complied with and whether more needs to be done," Hersman said. "We want to make sure the design is robust, that the oversight, the manufacturing process, that those are all adequate -- and so that will be a part of our continuing investigation to determine the failure modes, what may have caused it and what can mitigate against that in the future."


The lithium batteries, one power source for the 787, have never before been used in commercial airliners and were a source of concern from the beginning because of they operate at high temperature.


"I would not want to categorically say that these batteries are not safe," Hersman said. "Any new technology, any new design, there are going to be some inherent risks. ... I would say that, in the past, the NTSB have expressed concerns about the risks and recommended mitigation measures."


Hersman added that the fire seen on board the JAL Dreamliner in Boston in "shows us some risks that were not addressed."


In a statement to ABC News, Boeing said: "Lithium ion batteries were selected after a careful review of available alternatives because they best met the performance and design objectives of the 787. We've used them successfully in other applications, such as satellites, for nearly a decade, and they are used on other aircraft, spacecraft and naval vessels.


"With that said," Boeing added, "we constantly challenge our assumptions and decisions across all of our products when new information becomes available. Nothing we learned during the design of the 787 or since has led us to change our fundamental assessment of the technology. It merits emphasis that the 787 has extensive protections in place to ensure the ability for safe flight to continue even in the presence of a battery failure."

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.”
