Passion in US lower house immigration debate






WASHINGTON: US lawmakers debated plans on Tuesday to build a pathway to citizenship for millions of immigrants who remade their lives in America but found themselves at the heart of a fierce debate.

President Barack Obama and a group of Republican and Democratic senators have submitted plans for reform, but as the House of Representatives took up the issue, there were signs the bipartisan facade is coming under strain.

While from the Democratic side of the aisle, a rising Hispanic-American political star made an impassioned plea to fix a broken system, more senior Republicans warned against pushing too fast for change.

"Immigration is more than a political issue. It's who we are," said Julian Castro, the charismatic young mayor of San Antonio, Texas who had a star turn last year on the stage of the Democratic National Convention.

"Immigrants have made ours the greatest country in the world," he told a packed House Judiciary Committee hearing. "Doing nothing is not an option."

But Bob Goodlatte, chairman of the committee, warned against a "rush to judgment" -- despite concerns among his Republican colleagues that they have lost the support of a generation of Hispanic and Asian voters.

"I think we can all agree that our nation's immigration system is in desperate need of repair and it is not working as efficiently and fairly as it should be," he told the first of several hearings on the issue.

Goodlatte warned his panel "needs to take the time to learn from the past so our efforts to reform our immigration laws do not repeat the same mistakes."

The burst of activity on Capitol Hill marks the best chance in years to craft legislation to tighten border security, improve employment verification and bring some 11 million illegal immigrants out of limbo.

A 2007 effort spearheaded by then-president George W. Bush failed.

Obama and top Republicans are for once in agreement that political and demographic trends have suddenly shifted to offer the best chance for serious reform in a generation.

November's election saw Obama re-elected with 70 percent backing from Hispanic American voters -- many of whom have friends or relatives seeking papers.

It shook Republicans into realizing that their tough stance on immigration had driven Hispanics away from the party, and party luminaries like Senator Marco Rubio have come out strongly in favor of immigration reform.

But differences remain, particularly in the contentious issue of how to accommodate the millions who entered the country without permission, or who came in legally but overstayed their visas.

The issue bubbled over in the hearing room when about eight protesters stood up with fists raised, and chanted "undocumented and unafraid!" for about 30 seconds before walking out.

Castro said a pathway to citizenship, similar to the one proposed by the bipartisan group of senators last month, was crucial in order to bring 11 million undocumented immigrants "out of the shadows and into the full light of the American dream."

Republican Goodlatte pushed back, seeking to carve a possible compromise option short of full citizenship for those who entered illegally or stayed beyond their visa.

"Are there options that we should consider between the extremes of mass deportation and a pathway to citizenship for those not lawfully present in the United States?" Goodlatte asked.

Democratic congresswoman Zoe Lofgren, a former immigration lawyer from California, conceded the system was dysfunctional, but that "partial legalization, as some are suggesting, is a dangerous path."

She argued that merely providing undocumented workers with legal status but no way to work towards full citizenship could create a "permanent underclass," while kicking the undocumented out en masse would trigger economic chaos.

With up to 90 percent of the estimated two million migrant farm workers in the country illegally, "you could do e-verify and find out they're not properly here and American agriculture would collapse."

Obama addressed the immigration issue Tuesday as well, hosting meetings with more than two dozen progressive leaders and business executives.

Steve Case, co-founder of America Online, said he was encouraged by the discussion at the White House.

"The president and his team listened to numerous proposals, outlined many of their own and expressed a desire to build a bipartisan consensus regarding comprehensive immigration reform," Case said.

Apple wins design patents for slide-to-unlock, original iPhone

Apple was granted design patents today for the contentious slide-to-unlock user interface asset and the design for the original iPhone.


The U.S. Patent and Trademark Office approved Apple application No. D675,639 for "ornamental design for a display screen or portion thereof with a graphical user interface," which includes illustrations of the familiar horizontal bars with rounded corners found at the bottom of locked iOS screens since the original iPhone's debut in 2007.

Slide-to-unlock functionality has become a major sticking point with handset makers. Apple, which was granted a patent for the feature in 2011, has charged both Motorola and Samsung with violating patents related to the functionality.


Apple pressed the patent against Samsung's
Galaxy Nexus in January 2012, only to discover that Google had filed a patent application in 2010 that described a manner in which users interact with a smartphone -- or PC -- to unlock the device and perform at least one command.


An Apple patent infringement lawsuit filed in Germany against Motorola over the function was backburnered last March. The judge in that case said he wanted to wait until the German Patent and Trademark Office heard Apple's case before his court continued.

Apple was also granted approval for design patent No. D675,612, which covers the "ornamental design of an electronic device" -- specifically the rounded corners found on the iPhone. The design feature is key to Apple lawsuits against Samsung.


A judge with the U.S. International Trade Commission, a federal agency with the power to block imports of devices found to infringe on U.S. patents, ruled last October that Samsung had violated Apple's iPhone design patent covering the look and feel of the smartphone's exterior. That ruling is currently under review, and a decision is expected next month.

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


ht predator drone nt 121108 wblog Drone Strikes on US Terror Suspects Legal, Ethical, Wise, White House Says

U.S. Air Force


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.


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.”

Ice-age art hints at birth of modern mind



Sumit Paul-Choudhury, editor

The world’s oldest portrait, the world’s first fully carved sculpture, the world's oldest ceramic figure, the world’s earliest puppet - there’s no shortage of superlatives in the new exhibition of art from the ice age at the British Museum in London


But focus too closely on the exhibits’ record-breaking ages alone, and you might miss the broader point: these beautiful objects are the earliest evidence we have of humans who seem to have had minds like ours.






lionman.jpg

Consider, for example, the "lion man" found in 1939 in south-west Germany’s Stadel cave (pictured above). As the name suggests, this statue, standing 30 centimetres tall, harmoniously combines human and leonine features: the head is unmistakeably a lion’s, while the body and lower limbs are more human.


This is clearly the product of artistic creativity rather than a naturalistic drawing from life - suggesting that whoever carved it some 40,000 years ago had the capacity to express their imagination, as well as to replicate what they saw around them.


The temptation to speculate about what symbolic meaning the lion man might have had is, of course, irresistible. It was clearly valuable, taking around 400 hours and enormous skill to carve from a single piece of mammoth ivory.


The exhibition also includes a second, much smaller, feline figure found in another cave nearby, pointing to the idea that such imaginative objects might have cultural significance, perhaps as ritual objects within a shamanic belief system, rather than being isolated art objects.


Given what we know of modern traditions, that would make sense - but there is no hard evidence that anything resembling those traditions existed in Europe during the ice age.


Almost every object on show invites similarly thought-provoking consideration. Thumb-sized figurines from settlements along Russia's Don river (top) seem to present a woman's perception of her own pregnant body in an age before mirrors: no face, bowed head, the shelf of the bosom, the protrusion of the hips and buttock muscles and the swell of the belly. Were they carved by the women themselves, perhaps as protective talismans for themselves or their unborn children? And if so, what are we to make of those that were apparently deliberately destroyed subsequently?


Only a few of the animal models found at the Czech site of Dolní Věstonice are intact. The rest had shattered into thousands of clay fragments when they were heated while still wet. This must also have been deliberate: was the dramatic shattering part of a rite?


A tiny relief of a human figure with upraised arms invites interpretation as a celebrant or worshipper. Was he or she participating in a ceremony to promote social cohesion during tough times - perhaps to the accompaniment of music played on instruments such as the flute displayed nearby, which is precisely carved from a vulture's wing-bone?


Such interpretations deserve a healthy dose of caution, of course. The note accompanying an elegantly carved water bird (perhaps a cormorant) found near the smaller lion man drily reads: "This sculpture may be a spiritual symbol connecting the upper, middle and lower worlds of the cosmos reached by a bird that flies in the sky, moves on land and dives through water. Alternatively, it may be an image of a small meal and a bag of feathers."


In the total absence of documentary evidence, there is no way of telling which is correct: archaeological material might help clarify the utilitarian perspective, but it is far less helpful when it comes to discovering any symbolic value.


In any case, there is very little archaeological evidence on display at the British Museum. Curator Jill Cook says she was keen to avoid exhausting visitors with copious background material about the evolutionary and environmental contexts in which these objects were made.


Humans were capable of complex behaviour long before they reached Europe - as demonstrated by discoveries such as the 100,000-year old "artist's workshop" in South Africa's Blombos cave - but Cook thinks the explosion of art among Europeans 40,000 years ago may reflect changing social needs during the ice age.


When Homo sapiens first arrived in Europe some 45,000 years ago, "the living was initially probably reasonably easy", explains Cook. They would have found temperatures only about 5 °C lower than they are now, she says, and grassy prairies would have been well stocked with bison. As the human population grew, they would have had to find new ways of building, socialising and organising themselves.


“And as it turns desperately cold, around 40,000 years ago, suddenly we have all this art," she says.


That may have reflected the need to communicate and develop ideas - a need pressing enough for people to spend hundreds of hours creating objects that generally seem to have had little quotidian function.


"This is all about planning and preconceiving and organising and collaborating and compromising," suggests Cook, "and that is something art and music helps us do."


The dazzling array of objects on display, spanning tens of thousands of years, anticipate practically every modern artistic tradition. The first portrait, dating back 26,000 years, includes closely modelled details of its female subject's unusual physiognomy, perhaps the result of an injury or illness.


But nearby is an extraordinary figure of similar age whose facial features are utterly abstract, resembling a visor with a double slit in it.


picasso-inspiration.jpg

Another (above) has a body whose angular patterns anticipate Cubism by some 23,000 years: Picasso kept two copies of it in his studio. Elsewhere, there are doll-like models of women with stylised faces, and female forms streamlined into little more than slender, strategically curved lines.


movement.jpg

Representations of animals, too, come in all forms, from incredibly realistic illustrations scratched onto stone or ivory, to elegantly minimal sculptures; there are even carvings designed to create the illusion of movement when viewed from different angles or rotated (above) - a form of prehistoric animation.


The masterpieces in the latter part of the show include - and sometimes combine - both precisely observed, superbly rendered naturalism, and more abstract work that is still beautiful, but much harder to interpret.


tusks.jpg

Carved mammoth tusks


"The brain likes to tease us," says Cook. "We don't just represent things with great realism and naturalism, we like to break things down into patterns. That sparks your imagination, and makes you curious and questioning.


“What’s so spectacular about the modern brain, and the mind that it powers, is that it doesn't just make everything simple, it pushes us to new ideas and new thoughts."


After tens of thousands of years, the objects displayed in this extraordinary exhibition still have the power to do just that.

Football: Messi agility is all in the mind - scientists






LONDON: Barcelona superstar Lionel Messi may owe his trademark feints and body swerves to the fact his brain is busier than that of a less gifted player, according to a study into footballers' minds.

Researchers at Britain's Brunel University found that highly skilled footballers are able to activate more areas of their brain than novices when an opposing player approaches, enabling them to react to their moves more successfully.

Published in the Journal of Sport and Exercise Psychology, the research found that experienced players are able to suppress the urge to react instinctively, making them less likely to fall for opponents' attempts to trick them.

As part of the study, 39 players ranging from beginners to semi-professionals lay in an MRI brain scanner and watched clips of a junior international-level player running towards them with the ball.

Occasionally, the oncoming player would produce a deceptive manoeuvre and participants had to decide in which direction they need to move in order to counter.

They were then grouped according to how well they performed in the task, revealing that strong performers were more attuned to the actions and movements of opponents than their less-skilled counterparts.

"Our neuroimaging data clearly shows greater activation of motor and related structures in the brains of expert footballers, compared to novices, when taking part in a football-related anticipation task," said Daniel Bishop from Brunel University.

"We believe that this greater level of neural activity is something that can be developed through high quality training, so the next step will be to look at how the brain can be trained over time to anticipate the moves of opponents."

Amazon Studios taps John Goodman for "Alpha House" comedy



Imagine John Goodman strutting across the screen as a smooth-talking, deal-making Southern House member or senator. But, don't think of Kevin Spacey's conniving Francis Underwood in Netflix's "House of Cards."


Amazon Studios is reportedly tapping Goodman to play North Carolina Sen. Gil John Biggs in an upcoming comedy, "Alpha House." The new series, written by Doonesbury cartoonist Garry Trudeau, centers around four senators who live together in Washington, D.C.

"Alpha House" is just one piece of Amazon's ambitious foray into original content. In December 2012, Amazon announced that it was making a major investment in original content with six comedy pilots in the works with writers from hit shows such as the "The Daily Show," "30 Rock," "The Big Bang Theory," and The Onion, in addition to Trudeau.


Amazon also has a dozen children's show pilots, including from the creators of "Blue's Clues" and "Sid the Science Kid," and from The Jim Henson Company. Starting in June, Amazon Prime will be the only place to stream the latest episodes of popular British TV series "Downton Abbey."


No doubt Amazon, as well as Netflix, Hulu, YouTube, and others born of the web, want to be the new, streaming Hollywood. They are making substantial investments in developing, producing, and acquiring high-quality programming that competes with what the established broadcast and cable networks and studios put on television or in theaters. They have learned that aggregation of content is not enough of a differentiator to keep people in their seats, or in front of their
tablets or smart TVs.


Netflix's "House of Cards," which costs nearly $4 million per episode to produce, is part of a big bet by the streaming company to attract millions of new paying subscribers around the world. Netflix is also exclusively producing a horror thriller, "Hemlock Grove," that will debut on April 19; "Orange is the New Black" from the creator of "Weeds"; and "Derek" with Ricky Gervais. Netflix is also bringing a fourth season of "Arrested Development" in May to its subscribers. In addition, Netflix inked a major exclusive deal with Walt Disney to stream films from Walt Disney Animation Studios, Pixar Animation, Marvel, and Disneynature starting in 2016.


Hulu has new seasons of its exclusive series and a few new shows for 2013, including "The Awesomes," an animated show from SNL's Seth Meyers and Michael Shoemaker of "Late Night with Jimmy Fallon, and "The Wrong Mans," a drama about office workers who unexpectedly end up in the middle of a deadly criminal conspiracy. And, Google's YouTube is reportedly planning a subscription service as part of an overall plan to support more exclusive, high-quality content.


As Rep. Francis Underwood said in "House of Cards," "It doesn't matter how it happened -- we can't make it unhappen. Now we have to adapt." The leaders in streaming popular, high-quality content are adapting, and a new world order is gradually forming.

Space Pictures This Week: A Space Monkey, Printing a Moon Base

Illustration courtesy Foster and Partners/ESA

The European Space Agency (ESA) announced January 31 that it is looking into building a moon base (pictured in an artist's conception) using a technique called 3-D printing.

It probably won't be as easy as whipping out a printer, hooking it to a computer, and pressing "print," but using lunar soils as the basis for actual building blocks could be a possibility.

"Terrestrial 3-D printing technology has produced entire structures," said Laurent Pambaguian, head of the project for ESA, in a statement.

On Earth, 3-D printing, also known as additive manufacturing, produces a three-dimensional object from a digital file. The computer takes cross-sectional slices of the structure to be printed and sends it to the 3-D printer. The printer bonds liquid or powder materials in the shape of each slice, gradually building up the structure. (Watch how future astronauts could print tools in space.)

The ESA and its industrial partners have already manufactured a 1.7 ton (1.5 tonne) honeycombed building block to demonstrate what future construction materials would look like.

Boy Safe, Kidnapper Dead After Hidden Camera Tip













A week-long standoff in Alabama, where a retired trucker held a 5-year-old boy hostage in an underground bunker, has ended with the kidnapper dead and the child safe, according to law enforcement.


Officials had been able to insert a high-tech camera into the bunker to monitor the movements of the suspect, Richard Lee Dykes, and they had become increasingly concerned that he might act out, according to a law enforcement source with direct knowledge.


"FBI agents safely recovered the child who's been held hostage for nearly a week," FBI Special Agent Steve Richardson said at a news conference.


The agent said negotiations with Dykes "deteriorated" in the past 24 hours.


"Mr. Dykes was observed holding a gun," Richardson said. "At this point, the FBI agents, fearing the child was in imminent danger, entered the bunker and rescued the child."


The boy, identified only as Ethan, "appears physically unharmed" and is being treated at a hospital, authorities said.

Dykes, 65, is dead, but officials have not yet provided details on how he died.


"Right now, FBI special agent bomb technicians are in the process of clearing the property for improvised explosive devices," the FBI said in a written statement. "When it is safe to do so, our evidence response teams, paired with state and local crime scene technicians, will process the scene."

Dykes allegedly shot and killed a school bus driver last week and threatened to kill all the children on the bus before taking the boy, one of the students on the bus said.


"He said he was going to kill us, going to kill us all," Tarrica Singletary, 14, told ABC News.


Dykes had been holed up in his underground bunker near Midland City, Ala., with the abducted boy for a week as police tried to negotiate with him through a PVC pipe. Police had used the talks to send the child comfort items, including a red Hot Wheels car, coloring books, cheese crackers, potato chips and medicine.


Dykes was a decorated Vietnam vet who grew up in the area. He lived in Florida until two years ago, the AP reported, and has an adult daughter, but the two lost touch years ago, neighbor Michael Creel said. When he returned to Alabama, neighbors say he once beat a dog with a lead pipe and had threatened to shoot children who set foot on his property.
