(AP) ? A U.S. intelligence report concludes that North Korea has advanced its nuclear knowhow to the point that it could arm a ballistic missile with a nuclear warhead, a jarring revelation in the midst of bellicose threats from the unpredictable communist regime.

President Barack Obama urged calm, calling on Pyongyang to end its saber-rattling while sternly warning that he would "take all necessary steps" to protect American citizens.

The new American intelligence analysis, disclosed Thursday at a hearing on Capitol Hill, says the Pentagon's intelligence wing has "moderate confidence" that North Korea has nuclear weapons capable of delivery by ballistic missiles but that the weapon was unreliable.

Rep. Doug Lamborn, R-Colo., read aloud what he said was an unclassified paragraph from a secret Defense Intelligence Agency report that was supplied to some members of Congress. The reading seemed to take Gen. Martin Dempsey, chairman of the Joint Chiefs of Staff, by surprise, who said he hadn't seen the report and declined to answer questions about it.

In a statement late Thursday, Pentagon press secretary George Little said: "While I cannot speak to all the details of a report that is classified in its entirety, it would be inaccurate to suggest that the North Korean regime has fully tested, developed or demonstrated the kinds of nuclear capabilities referenced" in Lamborn's remarks.

'"The United States continues to closely monitor the North Korean nuclear program and calls upon North Korea to honor its international obligations," Little added.

The DIA conclusion was confirmed by a senior congressional aide who spoke on condition of anonymity because the Pentagon had not officially released the contents. The aide said the report was produced in March.

Since the beginning of March, the Navy has moved two missile defense ships closer to the coast of the Korean peninsula, in part to protect against a potential missile launch aimed at Guam, a U.S. territory in the Pacific. The Pentagon also has announced it will place a more advanced land-based missile defense on Guam, and Hagel said in March that he approved installing 14 additional missile interceptors in Alaska to bolster a portion of the missile defense network that is designed to protect all of U.S. territory.

On Thursday, the Pentagon said it had moved a sea-based X-band radar ? designed to track warheads in flight ? into position in the Pacific.

Notably absent from that unclassified segment of the report was any reference to what the DIA believes is the range of a missile North Korea could arm with a nuclear warhead. Much of its missile arsenal is capable of reaching South Korea and Japan, but Kim has threatened to attack the United States as well.

At the House Armed Services Committee hearing in which he revealed the DIA assessment, Lamborn asked Dempsey, whether he agreed with it. Dempsey said he had not seen the report.

"You said it's not publicly released, so I choose not to comment on it," Dempsey said.

But David Wright, a nuclear weapons expert at the Union of Concerned Scientists, said the DIA assessment probably does not change the views of those who closely follow developments in North Korea's pursuit of a nuclear weapon.

"People are starting to believe North Korea very likely has the capability to build a nuclear weapon small enough to put on some of their shorter-range missiles," Wright said. "Once you start talking about warheads small enough and technically capable to be on a long-range missile, I think it's much more an open question."

The DIA assessment is not out of line with comments Dempsey made Wednesday when he was asked at a Pentagon news conference whether North Korea was capable of pairing a nuclear warhead to a ballistic missile that could reach Japan or beyond.

In response, Dempsey said the extent of North Korean progress on designing a nuclear weapon small enough to operate as a missile warhead was a classified matter. But he did not rule out that the North has achieved the capability revealed in the DIA report.

"They have conducted two nuclear tests," Dempsey told a Pentagon news conference. "They have conducted several successful ballistic missile launches. And in the absence of concrete evidence to the contrary, we have to assume the worst case, and that's why we're postured as we are today." He was referring to recent moves by the U.S. to increase its missile defense capabilities in the Pacific.

At the same House hearing where Lamborn revealed the DIA conclusion, Defense Secretary Chuck Hagel was asked a different version of the same question: Does North Korea have the capability to strike U.S. territory with a nuclear weapon? Hagel said the answer is no.

"Now does that mean that they won't have it or they can't have it or they're not working on it?" Hagel added. "No. That's why this is a very dangerous situation."

"Now is the time for North Korea to end the belligerent approach they have taken and to try to lower temperatures," Obama said in his first public comments since Pyongyang threatened the United States and its allies in East Asia with nuclear attack.

Obama, speaking from the Oval Office, said he preferred to see the tensions on the peninsula resolved through diplomatic means, but added that "the United States will take all necessary steps to protect its people."

The North on Thursday delivered a fresh round of war rhetoric with claims it has "powerful striking means" on standby, the latest in a torrent of warlike threats seen by outsiders as an effort to scare and pressure South Korea and the U.S. into changing their North Korea policies.

Lamborn is a member of the Strategic Forces subcommittee of the Armed Services panel, which oversees ballistic missiles. A former state legislator who was elected to the House in 2006, was a member of the Tea Party caucus and belongs to the Republican Study Committee, the caucus of House conservatives

At a separate hearing Thursday, U.S. officials offered their assessment of the North Korean leader, who is a grandson of the country's founder, Kim Il Sung.

Director of National Intelligence James Clapper told the House Intelligence Committee that he thinks Kim, who took control after his father, Kim Jong Il, died in 2011, is trying to show the U.S., the world and his own people that he is "firmly in control in North Korea," while attempting to maneuver the international community into concessions in future negotiations.

"I don't think ... he has much of an endgame other than to somehow elicit recognition" and to turn the nuclear threat into "negotiation and to accommodation and presumably for aid," Clapper said.

Clapper said that the intelligence community believes the North would use nuclear weapons only to preserve the Kim regime but that analysts do not know how the regime defines that.

Secretary of State John Kerry was headed Thursday to East Asia, where he planned talks with officials in Seoul, Beijing and Tokyo about North Korea.

Google to invest $390m in data center in Belgium

(AP) ? Internet search giant Google says it is investing 300 million euros ($390 million) to expand its continental European data center.

Google Inc. said Wednesday it will upgrade the facility in Belgium to meet growing demand for its online services.

The information underpinning Google's services ? Internet search requests, Gmail or YouTube ? is processed in industrial-scale data centers such as the Belgian plant in St. Ghislain southwest of Brussels.

Google says the center currently has some 120 employees and is one of the most energy-efficient facilities of its kind.

The company, based in Mountain View, California operates other data centers catering for the European market in Ireland and Finland.

(AP) ? Philadelphia is getting ready for a supersized game of "Pong" ? on the side of a skyscraper.

The classic Atari video game will be re-created later this month on the facade of the 29-story Cira Centre, where hundreds of embedded LED lights will replicate the familiar paddles and ball.

Organizers expect hundreds of onlookers as gaming enthusiasts use giant, table-mounted joysticks to play from afar. The players will be standing on the steps of the Philadelphia Museum of Art, a site that offers an unobstructed view of the office building from across the Schuylkill River.

"'Pong' is a cultural icon, cultural milestone," said Frank Lee, the Drexel University game-design professor behind the concept. "This is my love letter to the wonders of technology as seen through the eyes of my childhood."

Despite the buzz the idea has received since being announced Wednesday, Lee said it took five years to find people willing to make it happen. He eventually met kindred spirits at Brandywine Realty Trust, which owns the Cira Centre, and at the online news site Technically Philly.

Now, what might be the world's largest "Pong" game will be played April 19 and 24 as part of Philly Tech Week, the news website's annual series of events, seminars and workshops spotlighting the city's technology and innovation communities.

"This is one of the best things I could imagine that could make people aware that there's something happening here, and bring more people into the fold," Technically Philly co-founder Christopher Wink said.

Wink estimated about 150 people might play over the two days ? most will be chosen by a lottery, but some spots will be reserved for younger students enrolled in science, technology, engineering and math programs.

Among those playing will be 36-year-old Brad Denenberg, one of three winners picked at random during a Tech Week preview on Wednesday. Denenberg, who runs the tech startup incubator Seed Philly, confessed to some trepidation. He said he's actually not a big gamer.

"My biggest fear is that I'm going to play against some 8-year-old who will destroy me," Denenberg said.

In today's gaming era of lifelike graphics ? think "Call of Duty" ? and colorful characters ? think "Angry Birds" ? it's hard to imagine how the pixelated "Pong" qualified as revolutionary when it was introduced in 1972.

The black-and-white arcade game used simple block shapes to simulate two paddles and a ball; the object was for players to hit the ball so their opponents could not return it. A home version paved the way for the game console industry.

At the Cira Centre, the game will be re-created using hundreds of lights already embedded in its north face. The tower stands by day as a gleaming, mirrored edifice in west Philadelphia, but each night it illuminates the skyline with colored, patterned displays. A spokesman could not be reached for comment Thursday.

Lee said he was driving by the building one night five years ago when he was suddenly struck with the idea that the lights could be configured to play the shape-fitting game Tetris.

The concept grew from there. Last month, after finally securing the necessary permissions, he and two colleagues successfully tested giant versions of "Pong" as well as the classic games "Snake" and "Space Invaders." People might get to play "Snake" on April 24, Lee said.

The effort has been satisfying on a technical level, Lee said, describing "Pong" as "a large-scale interactive, light-based art project."

But he noted it was rewarding on an emotional level as well, comparing it with the excitement he felt as a boy when he would put the "Pong" game cartridge into the console. And he hopes it inspires a new generation of innovators.

"I hope kids ... will go on to be the leaders, and push technology forward and do wondrous things in the future," Lee said.

NASA taps the power of zombie stars in two-in-one instrument

Apr. 8, 2013 ? Neutron stars have been called the zombies of the cosmos. They shine even though they're technically dead, occasionally feeding on neighboring stars if they venture too close. Interestingly, these unusual objects, born when a massive star extinguishes its fuel and collapses under its own gravity, also may help future space travelers navigate to Mars and other distant destinations.

NASA recently selected a new mission called the Neutron-star Interior Composition Explorer (NICER) to not only reveal the physics that make neutron stars the densest objects in nature, but also to demonstrate a groundbreaking navigation technology that could revolutionize the agency's ability to travel to the far reaches of the solar system and beyond.

The multi-purpose mission, also known as NICER/SEXTANT (Station Explorer for X-ray Timing and Navigation Technology), consists of 56 X-ray telescopes in a compact bundle, their associated silicon detectors, and a number of other advanced technologies. Both NASA's Science Mission Directorate's Explorers Program and the Space Technology Mission Directorate's Game Changing Program are contributing to the mission's development.

"It's rare that you have an opportunity to fly a cross-cutting experiment," said Principal Investigator Keith Gendreau, a scientist at NASA's Goddard Space Flight Center in Greenbelt, Md., who is leading NICER/SEXTANT's development. "The time is right for this experiment. This is one that we can do now."

In addition to NASA Goddard scientists and engineers, the mission team includes the Massachusetts Institute of Technology and commercial partners, who are providing spaceflight hardware. The Naval Research Laboratory and universities across the United States, as well as in Canada and Mexico, are providing science expertise.

Space Station Bound

Slightly larger than a typical college dormitory refrigerator, NICER/SEXTANT will be deployed on the International Space Station (ISS) in 2017. It will fly as an external attached payload on one of the ISS ExPRESS Logistics Carriers, unpressurized platforms used for experiments and storage.

The X-ray instrument's primary objective is to learn more about the interior composition of neutron stars, the remnants of massive stars that, after exhausting their nuclear fuel, exploded and collapsed into super-dense spheres about the size of New York City. Their intense gravity crushes an astonishing amount of matter -- often more than 1.4 times the content of the sun or at least 460,000 Earths -- into these city-sized balls, creating the densest objects known in the universe. Just one teaspoonful of neutron star matter would weigh a billion tons on Earth.

"A neutron star is right at the threshold of matter as it can exist -- if it were compressed any further, it would collapse completely in on itself and become a black hole," said Zaven Arzoumanian, a NASA Goddard scientist serving as the deputy principal investigator on the mission. "We have no way of creating or studying this matter in any laboratory. There are many theories about what it is and how it behaves, but the only way to test our models and understand what happens to matter under such incredible pressures is to study neutron stars," he added. "The closest we come to simulating these conditions is in particle accelerators that smash atoms together at almost the speed of light. However, these collisions are not an exact substitute -- they only last a split second, and they generate temperatures that are much higher than what's inside neutron stars."

Although the nuclear-fusion fires that sustained their parent stars are extinguished, neutron stars still shine with heat left over from their explosive formation, and from radiation generated by their magnetic fields that became intensely concentrated as the core collapsed.

Although neutron stars emit radiation across the spectrum, observing in the X-ray band offers the greatest insights into their structure, the ultimate stability of their pulses as precise clock "ticks," and the high-energy, dynamic phenomena that they host, including starquakes, thermonuclear explosions, and the most powerful magnetic fields known in the universe.

NICER's 56 telescopes will collect X-rays generated from its tremendously strong magnetic field and from hotspots located at the stars' two magnetic poles. At these locations, the intense magnetic field emerges from the surface. Particles trapped in the magnetic field rain down and generate X-rays when they strike the surface. As the hotspots rotate into and out of our line of sight, we perceive a rise and fall in X-ray brightness.

This subgroup of pulsating neutron stars, called pulsars, rotate rapidly, emitting from their magnetic poles powerful beams of light that sweep around as the star spins, much like a lighthouse. At Earth, these beams are seen as flashes of light, blinking on and off at intervals from seconds down to milliseconds.

Because of their predictable pulsations -- especially millisecond pulsars, which are the target of the navigation demonstration -- "they are extremely reliable celestial clocks" and can provide high-precision timing just like the atomic clock signals supplied through the 26-satellite, military-operated Global Positioning System (GPS), an Earth-centric system that weakens the farther one travels out beyond Earth orbit and into the solar system, Arzoumanian said. "Pulsars, on the other hand, are accessible in virtually every conceivable flight regime, from low-Earth orbit to interplanetary to deepest space," Gendreau added.

As a result, NICER/SEXTANT also will demonstrate the viability of pulsar-based navigation. "The hardware needed for neutron star science is identical to that needed for pulsar-based navigation," Gendreau said. "In fact, the mission's two goals share many of the same targets and the same operational concept. The differences are on the back end in terms of how the data will be used."

To demonstrate the navigation technology's viability, the NICER/SEXTANT payload will use its telescopes to detect X-ray photons within these powerful beams of light to estimate the arrival times of the pulses. With these measurements, the system will use specially developed algorithms to stitch together an on-board navigation solution.

If an interplanetary mission were equipped with such a navigational device, it would be able to calculate its location autonomously, independent of NASA's Deep Space Network (DSN), Gendreau said. DSN, considered the most sensitive telecommunications system in the world, allows NASA to continuously observe and communicate with interplanetary spacecraft. However, like GPS, the system is Earth-centric. DSN-supplied navigational solutions also degrade the farther one travels out into the solar system. Furthermore, missions must share time on the network, Gendreau said.

"We're excited about NICER/SEXTANT's possibilities," Gendreau added. "The experiment meets critical science objectives and is a stepping-stone for technology applications that meet a variety of NASA needs. It's rare that you get an opportunity to do a cross-cutting experiment like this."

EE to double 4G spectrum allocation, boost speeds in first ten cities by summer (Update: LTE-A testing starts this year)

EE plans to double 4G spectrum allocation, will boost first ten cities by summer

While EE scrambles to spread its LTE network far and wide before the other UK carriers get into the 4G business, it also wants to flex some spectrum muscle. The network's announced it's planning to double the LTE allocation on its 1800MHz band (from 2 x 10MHz to 2 x 20MHz), which it claims will increase download speeds to an average of 20 Mbps, topping out at 80 Mbps. Ten of the 11 original 4G launch cities will be seeing this bandwidth boost first: London, Birmingham, Bristol, Cardiff, Edinburgh, Glasgow, Leeds, Liverpool, Manchester and Sheffield. EE doesn't want you to think it's done expanding, though, and says it'll continue to make use of its MHz and GHz by rolling out boring, normal LTE in new areas whilst doubling up in others. The first ten cities are due to receive "double-speed" 4G by summer, which we assume means around the time summer is supposed to happen.

Update: EE's Howard Jones has added on Twitter that the network will start trialing carrier aggregation, LTE-A (that's even better 4G) later in 2013. We've asked for more details and will fill you in when we hear more.
