KFC cuts suppliers after China chicken scare

SHANGHAI: Fast food giant KFC has cut more than 1,000 farms from its supplier network in China to ensure food safety after a scandal over tainted chicken hurt sales in the key market last year.

The issue came to light when China's commercial hub of Shanghai and the northern province of Shanxi said in December that they were investigating KFC suppliers over claims of high levels of antibiotics in chicken.

The food scare caused a six percent fall in the China sales of KFC's parent Yum! Brands in the fourth quarter last year, deeper than its previous estimate of a four percent decline.

KFC will stop using chicken farms that have potential risk, improve the screening process of suppliers and step up self-inspections to address food safety concerns, the company said in a statement late Monday.

"It will always be our top priority to provide customers with the safest chicken with the best quality," Yum China's chairman and chief executive, Sam Su, said in the statement.

"We have seen some safety problems from the incident... and we aim to address the issue within the shortest time."

KFC also pledged to enhance communication with the government and the public, after the Chinese arm of Yum admitted last month that it failed to inform authorities about tests showing high levels of antibiotics in chicken.

Yum was aware of the issue through testing by a third-party in 2010 and 2011 but did not report to the authorities, the Shanghai government said in December.

China has seen several food safety incidents in recent years, including one of the biggest in 2008, when the industrial chemical melamine was found in dairy products which killed at least six babies and made 300,000 ill.

Facebook pages pop-up exploiting Newtown victims

Government officials and family members of victims from the Sandy Hook Elementary School shooting have asked Facebook to delete several offensive posts or tribute pages related to the massacre, according to the Associated Press.

Authorities have said that many of the Facebook pages are being used to berate survivors and victims' families, while others are fraudulently asking for funeral fund donations.

"Certainly there have been many, too many, of these pages that are intimidating or harassing or exploitive," U.S. Sen. Richard Blumenthal told the Associated Press.

Facebook has responded saying that it will work to remove the offending posts and pages but that some of the tribute pages help people share their sorrow.

Jodi Seth, a spokesperson for the social network, told the Associated Press that Facebook wants to respond quickly "while also recognizing that people across the country want to express grief for a terrible national tragedy."

In December, an armed man stormed the Connecticut elementary school and killed 26 people, including 20 children. Many of the victims have been memorialized and several of the survivors have been lauded on social networks. According to the Associated Press, more than 100 Facebook pages have been created and dedicated to Victoria Soto, one of the teachers killed in the shooting.

The insulting posts include conspiracy theorists who allege that the shooting was staged and all victims were actors. According to the Associated Press, a Facebook tribute page for survivor Kaitlin Roig -- the teacher who saved her students by barricading them in a bathroom -- has a post that reads, "Congratulations Kaitlin or whatever your name is.. Now you're famous and got to meet the 'President.' You ought to be ashamed of yourself."

Lawmakers have asked Facebook to remove the pages that are not authorized by the victims' families and to also make sure new fraudulent pages aren't created. Under Facebook's terms of use, it is prohibited for people to open accounts for anyone but themselves.

"We will continue to be vigilant," Seth told the Associated Press.

CNET contacted Facebook for comment. We'll update the story when we get more information.

Sharks Warn Off Predators By Wielding Light Sabers

Diminutive deep-sea sharks illuminate spines on their backs like light sabers to warn potential predators that they could get a sharp mouthful, a new study suggests.

Paradoxically, the sharks seem to produce light both to hide and to be conspicuous—a first in the world of glowing sharks. (See photos of other sea creatures that glow.)

"Three years ago we showed that velvet belly lanternsharks [(Etmopterus spinax)] are using counter-illumination," said lead study author Julien Claes, a biologist from Belgium's Catholic University of Louvain, by email.

In counter-illumination, the lanternsharks, like many deep-sea animals, light up their undersides in order to disguise their silhouette when seen from below. Brighter bellies blend in with the light filtering down from the surface. (Related: "Glowing Pygmy Shark Lights Up to Fade Away.")

Fishing the 2-foot-long (60-centimeter-long) lanternsharks up from Norwegian fjords and placing them in darkened aquarium tanks, the researchers noticed that not only do the sharks' bellies glow, but they also had glowing regions on their backs.

The sharks have two rows of light-emitting cells, called photophores, on either side of a fearsome spine on the front edges of their two dorsal fins.

Study co-author Jérôme Mallefet explained how handling the sharks and encountering their aggressive behavior hinted at the role these radiant spines play.

"Sometimes they flip around and try to hit you with their spines," said Mallefet, also from Belgium's Catholic University of Louvain. "So we thought maybe they are showing their weapon in the dark depths."

To investigate this idea, the authors analyzed the structure of the lanternshark spines and found that they were more translucent than other shark spines.

This allowed the spines to transmit around 10 percent of the light from the glowing photophores, the study said.

For Predators' Eyes Only

Based on the eyesight of various deep-sea animals, the researchers estimated that the sharks' glowing spines were visible from several meters away to predators that include harbor seals (Phoca vitulina), harbor porpoises (Phocoena phocoena), and blackmouth catsharks (Galeus melastomus).

"The spine-associated bioluminescence has all the characteristics to play the right role as a warning sign," said Mallefet.

"It's a magnificent way to say 'hello, here I am, but beware I have spines,'" he added.

But these luminous warning signals wouldn't impede the sharks' pursuit of their favorite prey, Mueller's bristle-mouth fish (Maurolicus muelleri), the study suggested. These fish have poorer vision than the sharks' predators and may only spot the sharks' dorsal illuminations at much closer range.

For now, it remains a mystery how the sharks create and control the lights on their backs. The glowing dorsal fins could respond to the same hormones that control the belly lights, suggested Mallefet, but other factors may also be involved.

"MacGyver" of Bioluminescence

Several other species use bioluminescence as a warning signal, including marine snails (Hinea brasiliana), glowworms (Lampyris noctiluca) and millipedes (Motyxia spp.).

Edith Widder, a marinebiologist from the Ocean Research and Conservation Association who was not involved in the current study, previously discovered a jellyfish whose bioluminescence rubs off on attackers that get too close.

"It's like paint packages in money bags at banks," she explained.

"Any animal that was foolish enough to go after it," she added "gets smeared all over with glowing particles that make it easy prey for its predators."

Widder also points out that glowing deep-sea animals often put their abilities to diverse uses. (Watch: "Why Deep-Sea Creatures Glow.")

"There are many examples of animals using bioluminescence for a whole range of different functions," she said.

Mallefet agrees, joking that these sharks are the "MacGyver of bioluminescence."

"Just give light to this shark species and it will use it in any possible way."

And while Widder doesn't discount the warning signal theory, "another possibility would be that it could be to attract a mate."

Lead author Julien Claes added by email, "I also discovered during my PhD thesis that velvet belly lanternsharks have glowing organs on their sexual parts."

And that, he admits, "makes it very easy, even for a human, to distinguish male and female of this species in the dark!"

The glowing shark study appeared online in the February 21 edition of Scientific Reports.

Take my taxi to the moon

Susmita Mohanty, the founder of India’s first private space company, Earth2Orbit, wants India to claim bigger piece of the space-launch pie

How active is India's space programme?
The Indian Space Research Organization (ISRO), which was founded in 1969, launches rockets, builds and uses satellites extensively for earthly applications and has recently started planetary exploration. It tested its first astronaut capsule for atmospheric re-entry in 2007, and is planning to build a residential astronaut training facility. ISRO is also planning a lunar lander mission for 2014 and will launch a mission to Mars this year.

How does your company, Earth2Orbit, fit in with this programme?
We want to commercialise India's space capabilities, in particular the Polar Satellite Launch Vehicle. It is one of the world's most reliable in its class. I want to make it the rocket of choice for international satellite-makers looking to get to low Earth or sun-synchronous orbits. India could build and launch up to six each year, but currently launches only two. We need to step up to full throttle. The same goes for satellites and ground equipment. Over the next decade or two, I think India should be aiming for at least a quarter of the multibillion-dollar global space market, if not more.

What do you think of the way spacecraft for carrying humans are currently designed?
The way the world aerospace industry is set up, it is closely linked to the defence sector – they share the technology, the tooling and the cumbersome contractual processes. Unlike commercial automobile or consumer-product companies, where the end user is the primary design driver, aerospace companies tend to please government customers. As a result, we often end up with over-engineered, under-designed crew craft with an exorbitant price tag.

How can we improve on these designs?
I want us to push the boundaries of technology and design and build intelligent spaceships – spaceships that think. Imagine if an international consortium of companies such as Apple, Samsung, Pininfarina, Space X and MIT Media Lab got together to design and build a spaceship! What would it look like? Could it think? Could it self-repair or self-clean? Would it challenge the crew?

The private sector is changing how we get into space. How has the X Prize contributed?
It created a tectonic shift in mindsets and showed how we can accelerate innovation in space exploration without having to spend taxpayer money. The first X Prize led to the first privately funded and designed spaceplane built by Burt Rutan. Then Richard Branson seized the opportunity: if all goes well, Virgin Galactic could fly more people to space in a year than the Russians or Americans have over the past 50 years!

What is next for space travel?
It barely takes 10 minutes to reach low Earth orbit. It probably takes longer for most urbanites to commute to work. I want to be able to "cab it" to low Earth orbit. I am dreaming of private astronaut taxis. The first generation will take paying passengers into orbit. The second generation will ferry us to the moon and Mars.

4 ex-SMRT bus drivers involved in illegal strike plead guilty

 

SINGAPORE: Four former SMRT bus drivers pleaded guilty in court on Monday and were convicted for inciting and participating in last November's illegal bus strike.

He Jun Ling, 32, Gao Yue Qiang, 32, Liu Xiangying, 33, and Wang Xian Jie, 39, had earlier claimed trial with trial dates set for the 4 to 8 March.

But last Friday, the four men's lawyers said their clients' decision to plead came after prosecution gave an indication of the various sentencing options.

On 26 November 2012, 171 SMRT bus drivers failed to report for duty in a protest over pay and living conditions.

Eighty-eight of them stayed away from work the next day.

In December 2012, a SMRT bus driver, Bao Feng Shan, 38, also from China, was sentenced to six weeks' jail for taking part in the same illegal strike.

New Nokia lineup spans range of budgets, features

The Nokia Lumia 520, in various colors.

Nokia)

Nokia took the wraps off four cell phones today at the Mobile World Conference in Barcelona, Spain, that run the gamut of entry level handsets to high-end Windows 8 devices.

With the entry-level Nokia 105, the Finish handset maker is thinking small. The durable 105 features a an itty-bitty 1.5-inch screen and a 15 euro price tag. Created for cell phone markets in China, Indonesia, India, and Nigeria, the Nokia 105 focuses on calls, long battery life, and only a few little extras.

There's no camera, no volume rocker, and the only buttons on this handset are on the central, rubbery alphanumeric dialpad. Since the screen requires such little power, the 800mAh battery lasts for more than 12.5 hours on talk time, Nokia says, and will power through 35 days on standby without a charge.

Nokia is targeting the younger crowd with the 301, a candy bar shape cell phone with a central select button and a camera feature that vocally guides users on how fit their face in the self-portrait frame. The handset sports a 2.4-inch QVGA display (320X240 pixel resolution) and a 3.2-megapixel camera (no flash) includes panorama and burst modes, which allows up to five shots in a sequence.

Nokia promises that battery life is long-lasting: a single-SIM 301 gives up to 20 hours of talk time, Nokia says, and up to 39 days of standby time. The 301 will go on sale in the second quarter for 65 euros, or about $85, in white, black, cyan, bright yellow, and magenta.

The Nokia Lumia 520 features a pronounced rounded back helps it fit comfortably into the contours of the palm and snappable covers that are exchangeable in different colors. The 520 sports a 4-inch LCD IPS supersensitivity screen 5-megapixel camera can record 720p HD video.

It sports a 1,430mAh battery, the 8GB mass storage, and support for 64GB in expandable memory. It'll be available in the U.S. through T-Mobile around late spring or early summer.

At the high end of Nokia's new lineup, the Windows 8 Nokia Lumia 720 has a 4.3-inch LCD display with the ClearBlack filter that reduces outdoor glare. Aimed at younger, trendier, social people, the 720 supports wireless charging and has a 6.7-megapixel camera with an f/9 aperture intended to capture low-light conditions (like nightlife) and LED flash.

There's also a 1.3-megapixel camera that supports Skype HD and has a wide-angle lens for fitting more faces into self-portraits. The unibody design features a microSD card slot, allowing storage expansion up to 64GB. Intended for markets in Asia and Europe in spots, the 720 will go on sale in the second quarter for 249 euros at full retail price, or about $338.

Picture Archive: Dorothy Lamour and Jiggs, Circa 1938

Dorothy Lamour, most famous for her Road to ... series of movies with Bing Crosby and Bob Hope, never won an Oscar. In her 50-plus-year career as an actress, she never even got nominated.

Neither did Jiggs the chimpanzee, pictured here with Lamour on the set of Her Jungle Love in a photo published in the 1938 National Geographic story "Monkey Folk."

No animal has ever been nominated for an Oscar. According to Academy Award rules, only actors and actresses are eligible.

Uggie, the Jack Russell terrier from last year's best picture winner, The Artist, didn't rate a nod. The equines that portrayed Seabiscuit and War Horse, movies that were best picture contenders in their respective years, were also snubbed.

Even the seven piglets that played Babe, the eponymous star of the best picture nominee in 1998, didn't rate. And the outlook seems to be worsening for the animal kingdom's odds of ever getting its paws on that golden statuette.

This year, two movies nominated in the best picture category had creatures that were storyline drivers with significant on-screen time. Neither Beasts of the Southern Wild (which featured extinct aurochs) or Life of Pi (which featured a CGI Bengal tiger named Richard Parker) used real animals.

An Oscar's not the only way for animals to get ahead, though. Two years after this photo was published, the American Humane Association's Los Angeles Film & TV Unit was established to monitor and protect animals working on show business sets. The group's creation was spurred by the death of a horse during the filming of 1939's Jessie James.

Today, it's still the only organization that stamps "No Animals Were Harmed" onto a movie's closing credits.

Editor's note: This is part of a series of pieces that looks at the news through the lens of the National Geographic photo archives.

Oscars 2013: 'Argo' Wins Best Picture

"Argo" took home the top prize as best picture at the Oscars Sunday night, with first lady Michelle Obama announcing the winner from the White House.

"You directed a hell of a film," co-producer Grant Heslov told director and fellow producer Ben Affleck. "I couldn't be more proud of the film and more proud of our director."

Affleck was snubbed in the directing category but humbly accepted the best picture Oscar as one of the three producers on the film. George Clooney was the third.

Affleck thanked Steven Spielberg and the other best picture nominees and his wife Jennifer Garner for "working on our marriage."

"It's good, it's work," he said, adding, "but there's no one I'd rather work with."

For Full List of Winners

Acknowledging his last Oscar win, as a screenwriter for "Good Will Hunting," Affleck said, "I was really just a kid. I never thought I would be back here."

In the acting categories, Daniel Day-Lewis won the Oscar for best actor, being the first actor to three-peat in that category. As he accepted the award from Hollywood's greatest actress, Meryl Streep, he joked, "I had actually been committed to play Margaret Thatcher. ... Meryl was Stephen's first choice for Lincoln."

He also thanked his wife, Rebecca Miller, for "living with some very strange men," with each new role that he takes on.

"She's the versatile one in the family and she's been the perfect companion to all of them," he said.

Daniel Day-Lewis Gets Laughs With Oscars Speech Watch Video

Jennifer Lawrence won the award for best actress. She tripped on the stairs on her way to accepting her award but picked herself up and made her way to the stage, earning a standing ovation.

"You're just standing up because you feel bad that I fell and that's embarrassing," she said, before rattling off a list of thank-yous and leaving the stage looking slightly stunned.

Watch Jennifer Lawrence's Oscar Tumble

"Life of Pi," which had a total of 11 nominations, was another big winner of the night. Director Ang Lee took home the Oscar for best director over Steven Spielberg and David O. Russell.

"Thank you, movie god," Lee said, accepting his award.

As expected, the film took home the first technical awards of the night for cinematography and visual effects. "Life of Pi" also won for best original score.

The first big acting awards of the night went to Christoph Waltz and Anne Hathaway in the supporting actor categories.

In one of the biggest tossups, Waltz claimed the award for supporting actor for his role in "Django Unchained." It was his second Oscar for a Quentin Tarantino film; his first was for Tarantino's "Inglourious Basterds."

PHOTOS: Stars on the Red Carpet

As expected, Hathaway took home the award for best supporting actress for her role as Fantine in "Les Miserables."

"It came true," she said, launching into a breathy speech, in which she thanked the cast and crew, her team and her husband. "The greatest moment of my life was when you walked into it," she said.

Tarantino won the Oscar for best original screenplay for his slave revenge western "Django Unchained." He thanked his cast.

"I have to cast the right people," he said. "And boy this time did I do it."

Chris Terrio won the award for best adapted screenplay for "Argo," which also won for film editing.

For only the sixth time in Academy history, there was a tie at the Oscars. "Zero Dark Thirty" and "Skyfall" tied for sound editing.

Amazon to open market in second-hand MP3s and e-books

A new market for second-hand digital downloads could let us hold virtual yard sales of our ever-growing piles of intangible possessions

WHY buy second-hand? For physical goods, the appeal is in the price – you don't mind the creases in a book or rust spots on a car if it's a bargain. Although digital objects never lose their good-as-new lustre, their very nature means there is still uncertainty about whether we actually own them in the first place, making it tricky to set up a second-hand market. Now an Amazon patent for a system to support reselling digital purchases could change that.

Amazon's move comes after last year's European Union ruling that software vendors cannot stop customers from reselling their products. But without technical support, the ruling has had no impact. In Amazon's system, customers will keep their digital purchases – such as e-books or music – in a personal data store in the cloud that only they can access, allowing them to stream or download the content.

This part is like any cloud-based digital locker except that the customer can resell previous purchases by passing the access rights to another person. Once the transaction is complete, the seller will lose access to the content. Any system for reselling an e-book, for example, would have to ensure that it is not duplicated in the transaction. That means deleting any copies the seller may have lying around on hard drives, e-book readers, and other cloud services, since that would violate copyright.

Amazon may be the biggest company to consider a second-hand market, but it is not the first. ReDigi, based in Boston, has been running a resale market for digital goods since 2011. After downloading an app, users can buy a song on ReDigi for as little as 49 cents that would costs 99 cents new on iTunes.

When users want to sell an item, they upload it to ReDigi's servers via a mechanism that ensures no copy is made during the transfer. Software checks that the seller does not retain a copy. Once transferred, the item can be bought and downloaded by another customer. ReDigi is set to launch in Europe in a few months.

Digital items on ReDigi are cheaper because they are one-offs. If your hard drive crashes and you lose your iTunes collection you can download it again. But you can only download an item from ReDigi once – there is no other copy. That is the trade-off that makes a second-hand digital market work: the risk justifies the price. The idea has ruffled a few feathers – last year EMI sued ReDigi for infringement of copyright. A judge denied the claim, but the case continues.

Used digital goods can also come with added charm. ReDigi tracks the history of the items traded so when you buy something, you can see who has owned it and when. ReDigi's second-hand marketplace has grown into a social network. According to ReDigi founder John Ossenmacher, customers like seeing who has previously listened to a song. "It's got soul like an old guitar," he says. "We've introduced this whole feeling of connectedness."

It could be good for business too if the original vendors, such as iTunes, were to support resale and take a cut of the resell price. Nevertheless, Amazon's move bucks the industry trend. Microsoft's new Xbox, for example, is expected not to work with second-hand games.

But the market could change rapidly now that Amazon's weight is behind this, says Ossenmacher. "The industry is waking up."
