Tokyo's Nikkei 225 hits 21-month high

Label:





TOKYO: Tokyo's benchmark Nikkei 225 index on Thursday closed at its highest level since the quake-tsunami disaster in March last year, a day after Japan's new conservative government took power.

The Nikkei added 0.91 percent, or 92.62 points, to 10,322.98 by the close, finishing above 10,254.43, its level on March 11, 2011 when a massive temblor hit Japan, sparking a tsunami and subsequent nuclear crisis.

The broader Topix index of all first-section shares was up 0.75 percent, or 6.38 points, at 854.09.

"Some say the market is now overbought, but the trend is your friend, and few are willing to risk going short at the moment," said an equity trading director at a foreign brokerage.

"Japan is now right in the middle of the radar for foreign portfolio managers."

In forex trade, the US dollar rose to its highest level in more than two years against the yen as Shinzo Abe was sworn in as prime minister.

Abe -- whose Liberal Democratic Party won a landslide election victory this month -- has repeatedly said he would pressure the Bank of Japan for more easing measures, comments that have helped bring down the value of the yen.

Pressure on Apple is improving labor practices, says Times

The attention brought to bear on the labor practices of Apple's manufacturers and suppliers in China may be starting to create real, positive change in the electronics industry, says an article published this evening in The New York Times.


The Times, along with other media outlets, published several high-profile reports this year on the practices of Apple suppliers -- including contract manufacturer Foxconn, which produces Apple's iPhone and
iPad, as well as products for other companies. The reports also included looks at Apple's lack of manufacturing facilities in the U.S. and its tax strategies.



Such media attention -- and the entry of the issue into mainstream consciousness, by way of skits on "Saturday Night Live" and questions during the presidential debates -- has, the Times reports, compelled executives in the electronics industry to realize they need to turn things around.


"The days of easy globalization are done," the paper quotes an unidentified Apple executive as saying. "We know that we have to get into the muck now."


Some of the positive steps the Times mentions are decreased hours and increased wages at Foxconn; a tripling of Apple's corporate social responsibility staff; increased transparency from Apple on practices and progress; and a new willingness on the part of Apple to reach out to worker-advocacy groups. Apple has also, the Times reports, stopped treating these labor issues "like engineering puzzles," and has adopted a "messier, more human approach" -- one with an increased focus on listening to workers and labor groups as opposed to simply establishing more policies.


The negative attention on industry giants Apple and Foxconn, as well as the positive changes it has begun to foster, are affecting the industry at large, the Times reports, with companies like HP and Intel, as well as Foxconn's competitors, getting swept up in the jetstream.


Intel's director of corporate responsibility, Gary Niekerk, tells the news outlet, "This is on the front burner for everyone now." No one inside Intel "wants to end up in a factory that treats people badly, that ends up on the front page."


Still, Apple has much work to do, the Times says. For one thing, the company's famous secrecy -- and that of Silicon Valley as a whole -- extends, wrongheadedly, to the sharing of information that could help improve labor conditions. And Apple has yet to truly don the mantle of industry leader in regard to concern for workers. As the Times puts it:




...Apple has not sought the high-profile leadership opportunities that have set off transformations in other industries. Nike, for instance, has convened public meetings of labor, human rights, environmental, and business leaders to discuss how to improve overseas factories. The clothing retailer Gap Inc. has invited outside organizations to critique its purchasing practices and publish their findings. Patagonia shares its factory audits with competitors and has been a vocal supporter of a centralized audit report clearinghouse that lets companies share information.


"That's the standard Apple has to meet," said a former Apple executive. "That's how a leader transforms an industry."



And the problem, too, is complex, and one that's not likely to be solved overnight, the Times reports. Some workers, for instance, were upset when Foxconn curtailed working hours. And there's a struggle between companies like Apple and their suppliers, like Foxconn, over which side should pay for improvements at manufacturing facilities.


Still, the Times concludes, though it may be slow-going, both Foxconn and Apple believe changes are "falling into place."


You can read the Times article in its entirety here. The paper has also published an extended statement from Apple on factory conditions in China, which says, among other things, "Apple is in a unique position to lead and we have embraced this role since the earliest days of our supplier responsibility program."

Okla. Senator Could Prevent Gun Control Changes

Label:











If there's one person most likely to keep new gun-control measures from passing Congress swiftly, it's Sen. Tom Coburn.


Conservatives revere the Oklahoma Republican for his fiscal hawkishness and regular reports on government waste. But he's also a staunch gun-rights advocate, and he's shown a willingness to obstruct even popular legislation, something in the Senate that a single member can easily accomplish.


That mixture could make Coburn the biggest threat to quick passage of new gun-control laws in the aftermath of the Newtown, Conn., shooting that has prompted even pro-gun NRA-member lawmakers like Sen. Joe Manchin, D-W.Va., to endorse a new look at how access to the most powerful weapons can be limited.


Coburn's office did not respond to multiple requests to discuss the current push for gun legislation. But given his record, it's hard to imagine Coburn agreeing to a major, new proposal without some fuss.


The last time Congress considered a major gun law -- one with broad support -- Coburn held it up, proving that the details of gun control are sticky when a conservative senator raises unpopular objections, especially a senator who's joked that it's too bad he can't carry a gun on the Senate floor.


After the Virginia Tech massacre in 2007, Congress heard similar pleadings for new gun limits, some of them similarly to those being heard now. When it came to light that Seung-Hui Cho, the mentally disturbed 23-year-old who opened fire on campus, passed a background check despite mental-health records indicating he was a suicide threat, a push began to include such records in determining whether a person should be able to buy a gun.




Rep. Carolyn McCarthy, D-N.Y., a longtime gun-control advocate whose husband was killed in a mass shooting on the Long Island Rail Road in 1996, introduced a widely supported bill to do just that. The NRA backed her National Instant Check System Improvement Amendments Act of 2007.


But Coburn didn't. The senator blocked action on the bill, citing concerns over patient privacy, limited gun access for veterans, and the cost of updating the background-check system,


In blocking that bill, Coburn pointed to a government study noting that 140,000 veterans had been referred to the background-check registry since 1998 without their knowledge.


"I am certainly understanding of the fact that some veterans could be debilitated to the point that such cataloguing is necessary, but we should ensure this process does not entangle the vast majority of our combat veterans who simply seek to readjust to normal life at the conclusion of their tours. I am troubled by the prospect of veterans refusing necessary treatment and the benefits they are entitled to. As I'm sure you would agree we cannot allow any stigma to be associated with mental healthcare or treatment of Traumatic Brain Injury," Coburn wrote to acting Veterans Secretary Gordon Mansfield.


Coburn succeeded in changing the legislation, negotiating a set of tweaks that shaved $100 million over five years, made it easier for prohibited gun owners to restore their gun rights by petitioning the government, and notifying veterans that if they abdicated control of their finances they would be added to the gun database. The bill passed and President Bush signed it in January 2008.

New Scientist 2012 holiday quiz

Label:
















Continue reading page

THIS was the year we held our breath in almost unbearable anticipation while we waited to see whether physicists at the Large Hadron Collider would finally get a clear view of the Higgs boson, so tantalisingly hinted at last December. Going a bit blue, we held on through March when one of the LHC's detectors seemed to lose sight of the thing, before exhaling in a puff of almost-resolution in July, when researchers announced that the data added up to a fairly confident pretty-much-actual-discovery of the particle.












Early indications were that it might be a weird and wonderful variety of the Higgs, prompting a collective gasp of excitement. That was followed by a synchronised sigh of mild disappointment when later data implied that it was probably the most boring possible version after all, and not a strange entity pointing the way to new dimensions and the true nature of dark matter. Prepare yourself for another puff or two as the big story moves on next year.













This respirational rollercoaster might be running a bit too slowly to supply enough oxygen to the brain of a New Scientist reader, so we have taken care to provide more frequent oohs and aahs using less momentous revelations. See how many of the following unfundamental discoveries you can distinguish from the truth-free mimics that crowd parasitically around them.












1. Which of these anatomical incongruities of the animal kingdom did we describe on 14 July?












  • a) A fish, found in a canal in Vietnam, that wears its genitals under its mouth
  • b) A frog, found in a puddle in Peru, that has no spleen
  • c) A lizard, found in a cave in Indonesia, that has four left feet
  • d) A cat, found in a tree in northern England, that has eight extra teeth

2. "A sprout by any other name would taste as foul." So wrote William Shakespeare in his diary on 25 December 1598, setting off the centuries of slightly unjust ridicule experienced by this routinely over-cooked vegetable. But which forbiddingly named veg did we report on 7 July as having more health-giving power than the sprout, its active ingredient being trialled as a treatment for prostate cancer?












  • a) Poison celery
  • b) Murder beans
  • c) Inconvenience potatoes
  • d) Death carrots

3. Scientists often like to say they are opening a new window on things. Usually that is a metaphor, but on 10 November we reported on a more literal innovation in the fenestral realm. It was:












  • a) A perspex peephole set in the nest of the fearsome Japanese giant hornet, to reveal its domestic habits
  • b) A glass porthole implanted in the abdomen of a mouse, to reveal the process of tumour metastasis
  • c) A crystal portal in the inner vessel of an experimental thorium reactor, to reveal its nuclear fires to the naked eye
  • d) A small window high on the wall of a basement office in the Princeton physics department, to reveal a small patch of sky to postgraduate students who have not been outside for seven years

4. On 10 March we described a new material for violin strings, said to produce a brilliant and complex sound richer than that of catgut. What makes up these super strings?












  • a) Mousegut
  • b) Spider silk
  • c) Braided carbon nanotubes
  • d) An alloy of yttrium and ytterbium

5. While the peril of climate change looms inexorably larger, in this festive-for-some season we might take a minute to look on the bright side. On 17 March we reported on one benefit of global warming, which might make life better for some people for a while. It was:












  • a) Receding Arctic sea ice will make it easier to lay undersea cables to boost internet speeds
  • b) Increasing temperatures mean that Greenlanders can soon start making their own wine
  • c) Rising sea levels could allow a string of new beach resorts to open in the impoverished country of Chad
  • d) More acidic seawater will add a pleasant tang to the salt water taffy sweets made in Atlantic City

6. In Alaska's Glacier Bay national park, the brown bear in the photo (above, right) is doing something never before witnessed among bearkind, as we revealed on 10 March. Is it:












  • a) Making a phonecall?
  • b) Gnawing at a piece of whalebone to dislodge a rotten tooth?
  • c) Scratching itself with a barnacle-covered stone tool?
  • d) Cracking oysters on its jaw?

7. Men have much in common with fruit flies, as we revealed on 24 March. When the sexual advances of a male fruit fly are rejected, he may respond by:












  • a) Whining
  • b) Hitting the booze
  • c) Jumping off a tall building
  • d) Hovering around the choosy female long after all hope is lost

8. While great Higgsian things were happening at the LHC, scientists puzzled over a newly urgent question: what should we call the boson? Peter Higgs wasn't the only physicist to predict its existence, and some have suggested that the particle's name should also include those other theorists or perhaps reflect some other aspect of the particle. Which of the following is a real suggestion that we reported on 24 March?

All 27 killed in Kazakh military plane crash

Label:





ALMATY, Kazakhstan: All 27 people on board a Kazakh military jet that crashed while carrying the Central Asian state's top border guard officials have died, the state security service said Wednesday.

"All 27 occupants of the aircraft, including seven crew members, have perished," the National Security Service (KNB) said in a statement.

The victims included the acting head of the Kazakh federal border service Turganbek Stambekov and his wife, the statement said.

The 22-year-old plane crashed late Tuesday about 20 kilometres (12 miles) from Shymkent airport where it had been due to land after a flight from the capital Astana.

Kazakhstan's KTK television said the jet fell from a height of 800 metres (2,600 feet). Witnesses also reported hearing a loud explosion at the time of the crash.

Footage of the crash site aired on Kazakh state television on Wednesday showed only fragments of the An-72 military transport plane remaining on the ground.

But the KNB security service stressed that the plane had recently undergone all the necessary checks and repairs.

"In 2012, it underwent restoration work at the Antonov repair plant in Ukraine," its statement said.

Khabar state television also cited local residents as saying that a heavy winter storm had descended on the region at the time of the accident.

It said the plane caught fire after the crash.

Kazakh official sealed off the site of the disaster on Wednesday as they launched an investigation into one of the most serious air accidents in the country's post-Soviet history.

The KNB statement said the senior security team, which also included the heads of the regional border guard services, had been flying to an end-of-year security meeting in Shymkent.

The border guard service of Kazakhstan -- a vast resource-rich nation nestled between China and Russia -- experienced a number of setbacks during the past year.

Its acting head Stambekov was appointed to his post in June after his predecessor was fired following a May incident in which 14 border guards were shot dead in a remote outpost in the south of the country.

The sole border guard to survive the shooting confessed during a subsequent trial that he killed his colleagues, but retracted his confession after being handed a life sentence, saying unidentified people in civilian clothes were responsible.

Aviation disasters remain a scourge across the former Soviet Union due to ageing hardware that often has not been replaced since the fall of the Soviet regime, as well as human error.

In November, eight people were killed in Kazakhstan when a Russian-made Mi-8 helicopter crashed while on a pipeline surveillance mission.

Stuxnet attacks Iran again, reports say

Label:



An Iranian news agency says the country successfully fended off yet another attack by the Stuxnet worm, according to reports.


The cyberattack targeted a power plant and other sites in southern Iran over the fall, the BBC and the Associated Press reported today.


Discovered in June 2010, Stuxnet is believed to be the first malware targeted specifically at critical infrastructure systems. It's thought to have been designed to shut down centrifuges at Iran's Natanz uranium enrichment plant, where stoppages and other problems reportedly occurred around that time. The sophisticated worm spreads via USB drives and through four previously unknown holes, known as zero-day vulnerabilities, in Windows.


Stuxnet is just one of several versions of malware aimed at Middle Eastern countries in the past two and a half years. Along Stuxnet, there have arisen Duqu, Gauss, Mahdi, Flame, Wiper, and Shamoon.

Photos: Humboldt Squid Have a Bad Day at the Beach

Label:

Photograph by Chris Elmenhurst, Surf the Spot Photography

“Strandings have been taking place with increased frequency along the west coast over the past ten years,” noted NOAA’s Field, “as this population of squid seems to be expanding its range—likely a consequence of climate change—and can be very abundant at times.” (Learn about other jumbo squid strandings.)

Humboldt squid are typically found in warmer waters farther south in theGulf of California (map) and off the coast ofPeru. “[But] we find them up north here during warmer water time periods,” said ocean sciences researcherKenneth Bruland with the University of California, Santa Cruz (UCSC).

Coastal upwelling—when winds blowing south drive ocean circulation to bring cold, nutrient-rich waters up from the deep—ceases during the fall and winter and warmer water is found closer to shore. Bruland noted that climate change, and the resulting areas of low oxygen, “could be a major factor” in drawing jumbo squid north.

Winter Storms Spawn Tornadoes Across South

Label:












A nasty Christmastime storm system spawned blizzard conditions in some states and at least 15 reported tornadoes in the South, damaging homes, taking out power lines and dangerously snarling holiday travel.


Severe weather swept across the United States during the Christmas holiday, bringing tornadoes and intense thunderstorms to the Gulf Coast, while dumping heavy snow and freezing rain on the Southern Plains.


At least 15 tornadoes were reported today from Texas to Alabama, putting this storm system potentially on track to be one of the largest Christmas day tornado outbreaks on record.


One large tornado was reported in Mobile, Ala., where there are about 19,000 customers without power and 23,429 statewide, according to Alabama Power. Kerry Burns, a Mobile resident originally from Boston, said the storm "sounded like a freight train."


Some buildings in the area, including some churches and a local high school, were reportedly damaged. Ray Uballe, another Mobile resident, said his dad was shaken up.


"He was in his apartment," Uballe said. "He said it sounded like an airplane and then the door flung open and then there was just debris flying."


Douglas Mark Nix, president of the Infirmary Health System, said one of their Mobile hospitals lost power and sustained damage. There were no early reports of injuries to staff or patients.


"We are operating now on generator power," he said. "We do not have substantial damage but we do have a number of windows out and we have some ceiling tiles down, throughout the facility at the main hospital.


"We can run for at least two weeks but I saw power crews out all over the city so I fully expect power to be restored within the next day or so," Nix added.

Winter Weather Causes Holiday Travel Problems Watch Video





At least eight states were issued blizzard warnings today, as the storms made highways dangerously slick heading into one of the busiest travel days of the year.


Oklahoma got about 7 inches of snow all over the state making for treacherous road conditions. ABC News affiliate KOCO-TV in Oklahoma City said the weather was being blamed for a 21-vehicle wreck on Interstate 40, but no one was seriously injured.


Ice accumulation in Arkansas bent trees and power lines, leaving at least 50,000 customers across the state without power. About 10 inches of snow fell on Fayetteville, Ark.


The storms, which first wreaked havoc on the West Coast before moving east, are being blamed for at least one death in Texas.


Investigators in the Houston area told ABC state KTRK-TV in Houston that a young man was trying to move a downed tree that was blocking the roadway when another one snapped and fell on top of him. He was later pronounced dead at a hopsital.


The last time a number of tornadoes hit the Gulf Coast area around Christmas Day was in 2009, when 22 tornadoes struck on Christmas Eve morning, National Weather Service spokesman Chris Vaccaro told ABC News over email.


The deadliest Christmastime tornado outbreak on record was Dec. 24 to 26, 1982, when 29 tornadoes in Oklahoma, Missouri, Arkansas, Tennessee and Mississippi killed three people and injured 32.


The last killer tornado around Christmas, Vaccaro said, was a Christmas Eve EF4 in Tennessee in 1988, which killed one person and injured seven. EF4 tornadoes can produce winds up to 200 mph.


No official word yet on the strength of the string of tornadoes reported today.


While some were preparing for a Christmas feast, others were hunkered down.


More than 180 flights nationwide were canceled by midday, according to the flight tracker FlightAware.com. More than half were canceled by American Airlines and its regional affiliate, American Eagle.


The storm system is expected to continue east into Georgia and the Carolinas Wednesday and could potentially spawn more tornadoes, according to the National Weather Service.


ABC News' Matt Gutman, Max Golembo and ABC News Radio contributed to this report.
