North Korea Says it Has Conducted a Nuclear Test













North Korea says it has successfully tested a miniaturized nuclear device Tuesday, according to state media.


A large tremor measured at magnitude 4.9 was detected in North Korea and governments in the region scrambled to determine whether it was a nuclear test that the North Korean regime has vowed to carry out despite international protests.


Official state media said the test was conducted in a safe manner and is aimed at coping with "outrageous" U.S. hostility that "violently" undermines the North's peaceful, sovereign rights to launch satellites. Unlike previous tests, North Korea used a powerful explosive nuclear bomb that is smaller and lighter, state media reported.


President Obama called the test "a highly provocative act" in a statement Tuesday morning.


"The danger posed by North Korea's threatening activities warrants further swift and credible action by the international community. The United States will also continue to take steps necessary to defend ourselves and our allies,"Obama said.


"The United States remains vigilant in the face of North Korean provocations and steadfast in our defense commitments to allies in the region," he added.


The U.N. Security Council will hold an emergency meeting on North Korea's nuclear test later this morning.


Suspicions were aroused when the U.S. Geological Survey said it had detected a magnitude 4.9 earthquake Tuesday in North Korea.


The Comprehensive Test Ban Treaty Organization told ABC News, "We confirm that a suspicious seismic event has taken place in North Korea."










North Korea Threatens More Nuclear Tests, Warns U.S. Watch Video







"The event shows clear explosion-like characteristics and its location is roughly congruent with the 2006 and 2009 DPRK (North Korea) nuclear tests," said Tibor Toth, executive secretary of the organization.


"If confirmed as a nuclear test, this act would constitute a clear threat to international peace and security, and challenges efforts made to strengthen global nuclear disarmament and non-proliferation," Toth said in a statement on the organization's web site.


Kim Min-seok, a South Korean Defense Ministry spokesman, told reporters that North Korea informed United States and China that it intended to carry out another nuclear test, according to the AP. But U.S. officials did not respond to calls from ABC News Monday night.


The seismic force measured 6 to 7 kilotons, according to South Korea.


"Now that's an absolutely huge explosion by conventional terms. It's a smallish, but not tiny explosion by nuclear terms. It's about two-thirds the size of the bomb that the U.S. dropped on Hiroshima," James Acton, a Senior Associate at the Carnegie Endowment for International Peace, told ABC News.


North Korea threatened in January to carry out a "higher-level" test following the successful Dec. 12 launch of a long range rocket. At the time, North Korea's leader Kim Jong-Un said his country's weapons tests were specifically targeting the United States.


The suspicious tremor comes just hours before President Obama is to give the State of the Union address, and it marks the first diplomatic test in the region for new Secretary of State John Kerry.


Also, South Korea's new president, Park Geun-hye, is scheduled to be sworn in on Feb. 25. One of North Korea's biggest holidays, Kim Jong-il's birthday, falls on Feb. 16.


China, North Korea's main ally in the region, has warned North Korea it would cut back severely needed food assistance if it carried out a test. Each year China donates approximately half of the food North Korea lacks to feed its people and half of all oil the country consumes.


Both of North Korea's previous tests used a plutonium-based method for making bomb fuel. The first was deemed a failure, the second only slightly less so. If the most recent test used HEU (highly enriched uranium), a far more difficult-to-detect method of producing bomb fuel, it would be a significant and worrisome step forward for North Korea's weapons program.

Being first lady’s guest at speech can yield positive and sometimes unexpected results



White House staffers will have coached those sitting in the gallery with Michelle Obama that at any moment the cameras might pan from the president’s podium to where they sit in the balcony. So they will watch their posture, stifle yawns and skip the chewing gum.


The everyday Americans invited to accompany the first lady as she watches her husband address Congress and the nation are essentially given roles by the White House. They are the human faces of the messages the president delivers, whether about the ingenuity of small business or the plight of returning troops.

This year, the president will focus on the economy and discuss issues such as gun control and immigration. A White House official said that victims of gun violence will be seated with the first lady, as will members of the middle class who would benefit from policy proposals that Obama will unveil, military families, and people working on immigration issues.

The speech will probably run an hour or so, and the next day, most guests will find themselves, Cinderella-like, back at their jobs and in schools and homes across the country.

Previous guests have found that the effects of the evening linger — in positive and sometimes tough or unexpected ways.

Attending the 2010 speech was a “game-changer” for Trevor Ya­ger. The founder of TrendyMinds, an Indianapolis-based advertising and public relations firm, Yager was invited, he says, to represent gay business owners thriving in a tough economy.

The attention he received — the local TV interviews, the national stories — caused a rift with a business partner. Soon after his return from Washington, the partnership dissolved, he said.

“There were jealousy issues,” Yager said. “When you have something like this come along, you do see people’s true colors.”

There were major benefits, too. He credits the exposure from attending the speech with the growth in his business. Trendy­Minds has grown from six or seven employees to 29. “All the coverage and attention helped attract clients and opened doors for us,” he said.

For Julia Frost, being a guest in 2010 complicated an already difficult relationship with her Republican father. The two are estranged, and although politics isn’t their only source of conflict, she says it contributes to the rift.

Growing up in a family of conservatives, Frost — who attended the speech as a veteran, a community college student and the wife of an active-duty Marine — says she’d always considered herself to be a Republican. But her visit to Washington made her question that.

She heard things from the president that she liked, about college and health care, and she was impressed by Obama’s demeanor.

“For a long time, I had been blindly following my family, but I saw that there was sense on both sides,” said Frost, who does not label herself a Democrat.

Another result of that night? She has a famous pen pal. Jill Biden, the wife of Vice President Biden, regularly corresponds with Frost. The women were seated together for the speech.

Tech giants summoned by Australia pricing inquiry






SYDNEY: Global technology giants Microsoft, Apple and Adobe were on Monday ordered to appear before a pricing inquiry examining the often-higher cost of tech goods in Australia compared with other economies.

The lower house committee holding the probe, which was launched last May, said it had summoned the trio to appear at a public hearing next month to explain why Australian customers paid more for the same products.

"The committee is looking at the impacts of prices charged to Australian consumers for IT products," it said in a statement.

"Australian consumers often pay much higher prices for hardware and software than people in other countries."

The inquiry was set up to examine claims by consumer advocacy groups of price discrimination for Australians on technology, with music, games, software, and gaming and computer hardware costing substantially more than elsewhere.

According to consumer lobby group Choice, Australians pay on average 73 percent more on iTunes downloads than the United States, 69 percent more on computer products and a staggering 232 percent more on PC game downloads.

Office software was on average 34 percent more expensive in Australia when compared with the United States, Choice said in its submission to the inquiry, with hardware coming in at 41 percent more expensive.

One software package was A$8,665 (US$8,939) more expensive to buy in Australia than the United States -- a gap that Choice described as "particularly unreasonable".

"For this amount, it would be cheaper to employ someone for 46 hours at the price of $21.30 per hour and fly them to the US and back at your expense -- twice," Choice said.

Choice only did comparisons to the United States and Britain; the inquiry is examining discrepancies with these countries as well as with Asia-Pacific economies.

Apple and Microsoft have both made their own submissions to the committee, arguing that prices differed across jurisdictions due to a range of factors including freight, local taxes and duties and foreign exchange rates.

The Australian Information Industry Association, which represents Adobe and other major ICT firms, has submitted to the committee that the "costs of doing business in Australia are higher than in many other countries".

It pointed to retail rent costs and high wages as some of the main factors behind business costs in Australia being "5-10 percent higher than any other country... and these costs are passed onto consumers".

Apple and Microsoft both declined to comment when contacted by AFP while Adobe said it would "cooperate with the committee as we have done since the inquiry began".

Year of the Snake: The Serpent Behind the Horoscope


On February 10, people all around the world will ring in the Lunar New Year with paper lanterns and firecrackers. At the heart of it all sits the snake, a slithery reptile feared for its sharp fangs and revered for its undeniable charm. (Watch videos of some of the world's deadliest snakes.)

Those born in the Year of the Snake are said to be intelligent and quick thinking, but they can also be dishonest and prone to show off. Though based on Chinese astrology, some of these traits are similar to characteristics of the actual serpent.

Snakes are known to be great at outsmarting their predators and prey. Their colorful, patterned skin makes them some of the best tricksters in the animal kingdom. And despite a bad rap as frightening creatures, snakes never fail to fascinate scientists, explorers, and zoo-goers. (See pictures of snakes.)

With more than 3,400 recognized species, snakes exhibit incredible diversity in everything from behavior and habitats to skin colors and patterns.

"As a vertebrate lacking in limbs, all snakes look largely like other snakes, yet they succeed in tremendous diversity in multiple directions," said Andrew Campbell, herpetology collections manager at the University of Kansas Biodiversity Institute.

To usher in the Year of the Snake, Campbell and herpetologist Dennis Ferraro at University of Nebraska-Lincoln weigh in on some of the snake's qualities that the Chinese zodiac predicts people born this year will have.

Horoscope: Snakes have an innately elegant personality but can also be ostentatious at times.

In Nature: Snakes come in all different colors, patterns, and textures, making them some of nature's most visually stunning creatures.

According to Campbell, the utility of their coloring falls into two main categories: to use as camouflage and to warn predators to stay away.

Among the most beautiful are the emerald tree boa (Corallus caninus)—whose vibrant green body is decorated with white stripes resembling lightning bolts—and the Brazilian rainbow boa (Epicrates cenchria), characterized by its iridescent skin and the large black rings down its back.

For some snakes, the diversity in color occurs within the same species, which is why Ferraro tells his student not to identify snakes by colors. For example, the polymorphic bush viper (Atheris squamigera), many of which are green, also come in shades of yellow, orange, red, and blue, as captured in photographer Guido Mocafico's "Serpent Still Life" photo series.

Horoscope: The snake is known to be the master seducer of the Chinese zodiac.

In Nature: Female garter snakes (Thamnophis) have all the luck with the gentlemen.

When a female garter snake is ready to mate, she announces it by producing chemicals called pheromones. Males, upon encountering the scent, immediately come crawling out and gather around the female in a large, wriggling "mating ball."

The competition intensifies when a male passing by the ball tries to fool the others by producing a scent that mimics that of the female, said Ferraro.

As soon as his rivals are led off in the wrong direction, the trickster slides right in. In areas with smaller populations of garter snakes, each ball consists of about 12 males and one female.

But in places like Manitoba, Canada, where garter snakes travel to certain areas to mate after coming out of hibernation, a mating ball can have thousands of males and only a hundred females.

Horoscope: Though snakes don't often tell lies, they will use deception when they feel it's necessary and they think they can get away with it.

In Nature: When it comes to using trickery to catch dinner, or to hide from predators, snakes are no amateurs.

Their sneaky techniques range from tricking fish to swim right into their mouths, to playing dead when threatened, to using their wormlike tails to lure in prey.

The most cunning of them all is the two-headed snake. To protect against a sneak attack from behind, the two-headed snake's tail looks just like its head. While the business end looks for food, the snake coils up its body and rests its tail on top to look like it is on guard.

The tail can even mimic the behavior of a retreating snake to trick predators into thinking they're going face-to-face with their opponent.

Horoscope: When snakes get down to work, they are organized and highly efficient, and they work quickly and quietly.

In Nature: While snakes are often perceived as lazy, Campbell said people are mistaken. "What we perceive as shy, lazy, or inactive is really efficiency," he said.

"On average, they are bigger than other lizards and can build a lot of body mass. They do that by being efficient in feeding and traveling." In other words, snakes don't move very much because they don't have to.

When it comes to food, snakes catch prey that are significantly larger than them so they can eat less frequently. This reduces the time they spend hunting and thus makes them less vulnerable to falling victim to a predator themselves.

For Campbell, the most impressive hunter is the eastern diamondback rattlesnake (Crotalus Adamanteus), which is able to hunt and kill its prey very quickly using venom, so it doesn't have to travel far. "Because they don't have to do that, they can become relatively large and heavy, being able to build up body mass and not having to spend that energy hunting."

Horoscope: Snakes are charming, with excellent communication skills.

In Nturea: For snakes, their visual and auditory senses don't mean much when it comes to communicating with each other.

Instead, they use their sense of smell and the chemicals produced by their musk glands. Unlike mammals, a snake picks up scent through the forks of its tongue.

When the snake retracts its tongue, it inserts the forks into grooves in an olfactory organ located at the roof of its mouth. Depending on which fork picks up a stronger scent, the snake knows in which direction to go when looking for prey or a mate.

It's when snakes are threatened that they use sight and sound, said Ferraro. Rattlesnakes, for example, shake their tails, making a loud rattling noise to ward off predators.

Possible Dorner Sighting Leads to Store Evacuation













A Northridge, Calif., home improvement store was evacuated tonight because of a possible sighting of suspected cop-killer Christopher Dorner, just hours after police announced a $1 million reward for information leading to his arrest.


As helicopters hovered overhead and a command center was established, police searched the Lowe's store and eventually told shoppers they could leave, but could not take their cars out of the parking lot.


LAPD spokesman Gus Villanueva said the major response to the possible sighting was a precaution, but couldn't say whether Dorner was in the area.


The announcement of the $1 million reward today came as authorities in Big Bear, Calif., scaled back their search for Dorner, the disgruntled ex-cop who is suspected in three revenge killings.


"This is the largest local reward ever offered, to our knowledge," Los Angeles Police Chief Charlie Beck said at a news conference today. "This is an act of domestic terrorism. This is a man who has targeted those that we entrust to protect the public. His actions cannot go unanswered."


The money for the reward was pooled by businesses, government, local law enforcement leaders and individual donors, Beck said.



PHOTOS: Former LAPD Officer Suspected in Shootings


The reward comes on the fourth day of a manhunt for Dorner, who has left Southern California on edge after he allegedly went on a killing spree last week to avenge his firing from the police force. Dorner outlined his grievances in a 6,000 word so-called "manifesto" and said he will keep killing until the truth is known about his case.

Dorner's threats have prompted the LAPD to provide more than 50 law enforcement families with security and surveillance detail, Beck said.


Authorities are chasing leads, however they declined to say where in order to not impede the investigation.


Dorner's burned-out truck was found Thursday near Big Bear Lake, a popular skiing destination located 80 miles northeast of Los Angeles.


Investigators found two AR-15 assault rifles in the burned-out truck Dorner abandoned, sources told ABC News.


The truck had a broken axle, which may be the reason he decided to set fire to it, the police sources said.


Full Coverage: Christopher Jordan Dorner


Officers have spent the past couple of days going door-to-door and searching vacant cabins. The manhunt was scaled back to 25 officers and one helicopter in the resort town today, according to the San Bernadino Sheriff's Office.


On Saturday, Beck announced he would reopen the investigation into Dorner's firing but said the decision was not made to "appease" the fugitive ex-cop.


"I feel we need to also publicly address Dorner's allegations regarding his termination of employment, and to do so I have directed our Professionals Standards Bureau and my Special Assistant for Constitutional Policing to completely review the Dorner complaint of 2007; To include a re-examination of all evidence and a re-interview of witnesses," Beck said. "We will also investigate any allegations made in his manifesto which were not included in his original complaint."


Dorner is suspected of killing Monica Quan and her fiancé Keith Lawrence last Sunday in their car in the parking lot of their Irvine, Calif., condominium complex. Both were struck with multiple gunshot wounds.


Quan's father, Randal Quan, was a retired captain with the LAPD and attorney who represented Dorner before a police review board that led to Dorner's dismissal from the force in 2008.


On Wednesday, after Dorner was identified as a suspect in the double murder, police believe he ambushed two Riverside police officers, killing one and wounding the other.


The next day, Randal Quan reported he received a taunting call from a man claiming to be Dorner who told him that he "should have done a better job of protecting his daughter," according to court documents documents.


Anyone with information leading to the arrest of Christopher Dorner is asked to call the LAPD task force at 213-486-6860.


ABC News' Dean Schabner, Jack Date, Pierre Thomas, Jason Ryan and Clayton Sandell and The Associated Press contributed to this report.

Many 2011 federal budget cuts had little real-world effect



“The largest annual spending cut in our history,” President Obama called it in a televised speech. To prevent a government shutdown, the parties had agreed to slash $37.8 billion: more than the budgets of the Labor and Commerce departments, combined.


At the Capitol, Republicans savored a win for austerity. There would be “deep, but responsible, reductions in virtually all areas of government,” House Appropriations Committee Chairman Harold Rogers (R-Ky.)
promised a few days later, before the deal passed.

Nearly two years later, however, these landmark budget cuts have fallen far short of their promises.

In some areas, they did bring significant cutbacks in federal spending. Grants for clean water dried up. Cities got less money for affordable housing.

But the bill also turned out to be an epic kind of Washington illusion. It was stuffed with gimmicks that made the cuts seem far bigger — and the politicians far bolder — than they actually were.

In the real world, in fact, many of their “cuts” cut nothing at all. The Transportation Department got credit for “cutting” a $280 million tunnel that had been canceled six months earlier. It also “cut” a $375,000 road project that had been created by a legislative typo, on a road that did not exist.

At the Census Bureau, officials got credit for a whopping $6 billion cut, simply for obeying the calendar. They promised not to hold the expensive 2010 census again in 2011.

Today, an examination of 12 of the largest cuts shows that, thanks in part to these gimmicks, federal agencies absorbed $23 billion in reductions without losing a single employee.

“Many of the cuts we put in were smoke and mirrors,” said Rep. Mick Mulvaney (R-S.C.), a hard-line conservative now in his second term. “That’s the lesson from April 2011: that when Washington says it cuts spending, it doesn’t mean the same thing that normal people mean.”

Now the failures of that 2011 bill have come back to haunt the leaders who crafted it. Disillusionment with that bill has persuaded many conservatives to reject a line-by-line, program-by-program approach to cutting the budget.

Instead, many have embraced the sequester, a looming $85 billion across-the-board cut set to take effect March 1. Obama and GOP leaders have said they don’t like the idea: the sequester is a “dumb cut,” in Washington parlance, which would cut the government’s best ideas along with its worst without regard to merit.

But at least, conservatives say, you can trust that this one is for real.

“There has been a shift in resolve. They have been burned in these fictional cuts. And so the sequester is like real cuts,” said Chris Chocola, a former congressman who now heads the Club for Growth, a conservative advocacy group. “So I think that there is a willingness to say, ‘We’ve really got to cut stuff, and [the cuts] have got to be real.”

China ships in disputed waters as tension runs high






TOKYO: Four Chinese ships were spotted Sunday in disputed East China Sea waters, Japanese officials said, as Tokyo considered disclosing video footage and pictures as evidence of a Chinese frigate's alleged radar-lock incident.

For the first time after Tokyo made the allegation last week, China sent maritime surveillance vessels near Japanese-controlled islands in the East China Sea, known as Senkaku in Tokyo and Diaoyu by Beijing, which also claims them.

They were seen sailing in the contiguous waters near one of the outcrops as of 0000 GMT, the Japan Coast Guard said.

Tokyo accused a Chinese frigate of locking its weapons-tracking radar on a Japanese destroyer -- the first time the two nations' navies have locked horns in the territorial dispute that has provoked fears of armed conflict breaking out between the two.

Japan's Prime Minister Shinzo Abe on Friday demanded Beijing apologise and admit to the incident, which occurred late January, after Chinese authorities flatly denied Tokyo's accusation.

Japan's Defence Minister Itsunori Onodera said on Fuji TV on Sunday that Tokyo was carefully studying whether or how to disclose military data as evidence.

However, he also said he did not think China would "admit to it even if Japan discloses a variety of evidence, because it is trying to protect its national interest".

Onodera on Saturday told the Yomiuri Shimbun newspaper that Tokyo had "evidence to show the fire-control radar chased after the ship (of Japan's Self-Defence Forces) for some time. The visual evidence would convince many of those who watch it".

The long-running row over the islands intensified in September when Tokyo nationalised part of the chain, triggering fury in Beijing and huge anti-Japan demonstrations across China.

Beijing has repeatedly sent ships and aircraft near the islands and both sides have scrambled fighter jets, though there have been no clashes.

Post Afzal hanging, rights groups demand India end executions

NEW YORK/LONDON: In the wake of the hanging of Parliament attack convict Afzal Guru, global rights groups have asked India to end the use of executions and move towards abolishing the death penalty.

"Questions need to be asked why the Indian government executed Afzal Guru now," New York-based Human Rights Watch's South Asia director Meenakshi Ganguly said.

"No one argues that those who engage in serious crimes shouldn't be punished, but the death penalty is brutal and irreversible, and there is no convincing evidence to suggest it serves as a deterrent," Ganguly said.

The group said it opposes the death penalty in all circumstances as an inherently irreversible, inhumane punishment.

The hanging of Guru comes just three months after India executed the lone surviving 26/11 terrorist Ajmal Kasab in a Pune jail.

"India should end this distressing use of executions as a way to satisfy some public opinion," said Ganguly.

"It should instead join the nations that have chosen to abolish capital punishment," she said.

Guru's execution makes it more urgent for India to reinstate its previous informal moratorium on executions as a step towards abolishing the death penalty, the rights group added.

Meanwhile, London-based Amnesty International has also expressed concern over Afzal's execution.

"We condemn the execution in the strongest possible terms. This very regrettably puts India in opposition to the global trend towards moving away from death penalty", said Shashikumar Velath, Programmes Director at Amnesty International India.

He alleged "serious questions have been raised about the fairness of Afzal Guru's trial. He did not receive legal representation of his choice or a lawyer with adequate experience at the trial stage. These concerns were not addressed".

"Before Ajmal Kasab's execution in November, Indian authorities used to make information about the rejection of mercy petitions and dates of execution available to the public prior to any executions. The new practice of carrying out executions in secret is highly disturbing," Velath said.

Guru was executed early yesterday for providing logistical support in the attack on the Indian parliament in December 2001, in which five heavily-armed gunmen entered the complex and opened fire indiscriminately, killing nine, including six security personnel, two parliament guards, and a gardener. All five attackers were also killed.

Mars Rover Curiosity Completes First Full Drill


For the first time in history, humans have drilled a hole into rock on Mars and are collecting the powdered results for analysis, NASA announced Saturday.

After weeks of intensive planning, the Mars rover Curiosity undertook its first full drill on Friday, with NASA receiving images on Saturday showing that the procedure was a success.

Curiosity drilled a hole that is a modest 2.5 inches (6.35 centimeters) deep and .6 inches (1.52 centimeters) wide but that holds the promise of potentially great discoveries. (Watch video of the Mars rover Curiosity.)

"The most advanced planetary robot ever designed now is a fully operating analytical laboratory on Mars," John Grunsfeld, NASA associate administrator for the agency's Science Mission Directorate, said in a statement on Saturday.

"This is the biggest milestone accomplishment for the Curiosity team since the sky-crane landing last August."

Read: Asteroid to Make Closest Flyby in History

The site of the much-anticipated penetration is a flat section of Mars rock that shows signs of having been underwater in its past.

Called Yellowknife Bay, it's the kind of environment where organic materials—the building block of life—might have been deposited and preserved long ago, at a time when Mars was far wetter and warmer than it is today.

The contents of the drilling are now being transferred into the rover's internal collection system, where the samples will be sieved down to size and scoured to minimize the presence of contamination from Earth. (Watch video of Curiosity's "Seven Minutes of Terror.")

Then the sample will be distributed to the two instruments most capable of determining what the rocks contain.

The first is the Sample Analysis on Mars (SAM), which has two ovens that can heat the powdered rock to almost 2000°F (1093°C) and release the rock's elements and compounds in a gaseous form.

The gases will then be analyzed by instruments that can identify precisely what they are, and when they might have been deposited. Scientists are looking for carbon-based organics believed to be essential for any potentially past life on Mars.

Powder will also go to the Chemistry and Mineralogy (CheMin) instrument for a related analysis that looks especially at the presence of minerals—especially those that can only be formed in the presence of water.

Louise Jandura, chief engineer for Curiosity's sample system at NASA's Jet Propulsion Laboratory, said that designing and testing a drill that can grab hold of Martian rock and commence first a percussive shallow drilling and then dig a deeper hole was difficult.

The drill, which is at the end of a 7-foot arm, is capable of about 100 discrete maneuvers.

"To get to the point of making this hole in a rock on Mars, we made eight drills and bored more than 1,200 holes in 20 types of rock on Earth," Jandura said in a statement.

Results from the SAM and CheMin analyses are not expected for several days to weeks.
