NY Times to rebrand Herald Tribune in its own image

NEW YORK: For a decade the International Herald Tribune has been the global edition of the New York Times in all but name. On Monday, the parent company made it official.

In a statement, the New York Times Company said the 125-year-old offshoot of the defunct New York Herald Tribune will be rechristened sometime this fall as the International New York Times.

"The digital revolution has turned the New York Times from being a great American newspaper to becoming one of the world's best-known news providers," said New York Times Company chief executive Mark Thompson.

"We want to exploit that opportunity," said the former BBC boss, adding that a new website for international readers is also in the pipeline.

The International Herald Tribune (IHT) was co-owned by the New York Times and the Washington Post from 1967 until 2003, when the Times became its sole proprietor and restyled it as "the global edition of the New York Times."

It almost exclusively showcased New York Times content in a bid to appeal to high-earning anglophone globe-trotters in competition with global editions of the Wall Street Journal and Britain's Financial Times.

Sold in more than 160 countries and territories, it has a daily circulation of more than 226,000, an IHT spokeswoman told AFP by email.

Prior to 1967 the IHT was known as the Paris edition of the New York Herald Tribune -- immortalized in Jean-Luc Godard's New Wave classic "Breathless" by Jean Seberg in a tight yellow T-shirt hawking copies on the Champs-Elysees.

The New York Times published an international edition under its own name from 1946 until it bought into "the Trib" and helped oversee its development as a global media brand through the use of satellite printing plants.

"I have to say I'm sorry to see the Herald Tribune go," said Charles Robertson, author of "The International Herald Tribune: The First 100 Years" and an IHT reader since his childhood in Switzerland.

"I suppose, once the Times pushed out the Washington Post, it was probably inevitable," Robertson, a professor emeritus at Smith College in Northampton, Massachusetts, told AFP.

News of the rebranding came less than three weeks after the New York Times Company posted a 2012 group profit of $133 million, compared with a loss of $39.7 million in 2011.

It gave no breakdown of profit or loss figures for its newspapers, but earlier this month it said it was putting the Boston Globe and other New England assets up for sale to focus on its eponymous core product.

"The New York Times is a very strong brand in the United States (and) there are enough people globally who still read it," said Joscelyn MacKay, senior securities analyst at Morningstar in Chicago.

"The content itself will have to become a bit more global ... but I think it is a definite feasible target for them," she told AFP.

"Whether or not it's going to move the needle over the long run remains to be seen, given the challenges that print media faces."

The International New York Times "will be edited from Hong Kong, Paris, London and New York," according to Monday's statement, and new investments will be made "in print, web and mobile platforms."

IHT spokeswoman Vicky Taylor, in an email from London, said there are "currently no plans to cut staff numbers or offer buyouts."

Half of those on the IHT payroll are in France, where labor costs are higher than the United States or Britain.

"In many ways it will be business as usual at the IHT because as an organization we've already taken significant steps to align with the New York Times to the benefit of readers and advertisers," Taylor said.

"Making the full transition to a multi-platform International New York Times is the next logical step."

OMG! Google's Andy Rubin worries Samsung may become a threat

Visitors look at new Samsung devices during the first day of the Mobile World Congress 2013 in Barcelona, Spain.

Andy Rubin, who heads up Google's enormously successful
Android business, can read a company's business strategy as well as anyone out there. So it's hardly a thunderbolt when we hear that Rubin frets about the day when Samung becomes so dominant that it becomes a threat. In a Wall Street Journal post coinciding with the Mobile World Congress show in Barcelona this week, an unnamed source dishes about a Google event last fall where Rubin was said to allude to the potential for trouble with Samsung sometime in the future. That's why Google acquired Motorola Mobility "as a kind of insurance policy, or "hedge," against a company like Samsung gaining too big a footprint in the Android community, Rubin reportedly said.

Sounds about right. I suppose the bigger shock would be if Rubin had been oblivious to any of this. Samsung's emergence the last few years ranks as one of the more remarkable stories in the technology business. It wasn't so long ago that this was little more than a big OEM supplier. Now it's the world's biggest maker of Android-based hardware. Give the Googlers credit for knowing their history-- and maybe that will help them prevent repeating it. The names change but this is all part of a familiar business storyline. Eric Schmidt, who battled against Microsoft when he worked for Sun Microsystems and Novell, watched how the once-close relationship between Microsoft and its biggest customer IBM, frayed and turned contentious during the years-long rivalry between Windows and OS/2. There's nothing so far to suggest that Google and Samsung are fated to head down a similar road but as the WSJ's nicely-written narrative makes clear, this is getting complicated.

For now -- and probably the near-future -- Google and Android remain partners. Samsung accounted for about 200 million more Android smartphones than the nearest Android-device manufacturer and that gives Samsung leverage. With that heft also comes the power to demand better pricing, earlier access to technology other terms and conditions. For now, Google may be able to live with all that, especially given that both companies have a common rival in the form of Apple.

However, this relationship will require a lot of TLC to manage, especially if the current trends accelerate (and based so far on what's coming out of Barcelona, there's nothing to suggest that any would-be challengers are close to offering the sort of show-stoppers which might slow Samsung's momentum.) For a company like Google, which has been able to call the shots for most of its (relatively) young history, I suppose it's a good problem to have. The flip side of success. But it also may be a harbinger suggesting that the topdog-underdog relationship between Google and Samsung is fated to get redefined.

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.

Arias Had No Remorse: Prosecutor

Accused murderer Jodi Arias was confronted today with a barrage of lies she told after she killed her ex-boyfriend Travis Alexander, but she twice defiantly declared that she was innocent of first degree murder.

"It's the truth. I'm innocent of that charge," Arias said to prosecutor Juan Martinez, referring to the criminal charge that could carry the threat of the death sentence if she is found guilty.

Arias admitted on the stand that she lied for months and years after killing her ex-boyfriend, telling investigators and friends that she had nothing to do with Alexander's grisly death, in which he was stabbed 27 times, his throat was slashed, and he was shot in the head.

Eventually, Arias confessed to the killing, but claims it was in self-defense.

Today, prosecutors hammered Arias about her lying, getting her to admit to lies she told and playing video of her police interrogation and a TV interview in which she told stories that she has since conceded were not true.

See the Evidence in the Jodi Arias Murder Trial

In an interview with NBC's "48 Hours," Arias said she smiled for her mug shot partly because she knew she was innocent.

"You truly believe that you didn't do anything wrong here?" the prosecutor asked incredulously.

"I believed that I knew that I was not guilty of first-degree murder and I did plan to be dead," she replied, a reference to her claim that she planned to commit suicide.

During a day of contentious questions and answers between Martinez and Arias, the prosecutor used Arias' own diary entries and text messages to show contradictions of her claims that Alexander was abusive toward her, that he hit her and tried to choke her.

Arias said that in early 2008, Alexander hit her in the neck while they were riding in his car. Martinez showed a diary entry describing the day they rode in the car, and there was no mention of physical violence.

"This entry does not corroborate what you told us happened in the car," he said. "With regard to the (choking incident) you didn't call police. You didn't tell anyone about it. There is no corroboration anywhere in your journal. All we have is your word. Are there photos? Any other writings? Is there a police report? Is there a medical report?"

Arias said there was no evidence that the alleged abuse happened, except for her testimony in court.

"There's no evidence because it didn't happen, did it ma'am?" Martinez yelled.

Arias said that she had told one person about the abuse she claims she suffered at the hands of Alexander, and that it was another ex-boyfriend, Matthew McCartney. But when pressed for details about the conversation in which she told him, Arias became confused and changed her answers.

"I saw (Matt) a few days later, and he called me out on the bruises," Arias testified.

"Where?"

"Over the phone, just days after I think," she said.

"Isn't it true he wouldn't have been able to see your injuries because you were talking over the telephone?"

"No, I was in Yreka (California) by then. I stopped to see Matt after I left Arizona. Let's see, I believe it was two or three days after. I'm not saying there was no telephone call, (but) it was at his house. I went and saw Matt, and some make-up wore off, and he confronted me on (the bruises)."

Martinez said that McCartney has denied the conversation ever took place.

Ancient continent hides beneath Indian Ocean

The sands of Mauritius are hiding a secret: deep beneath them lurks an ancient continent.

Trond Torsvik and colleagues at the University of Oslo, Norway, analysed grains of zircon found on the island's beaches, measuring the balance of lead and uranium isotopes to work out their age. This showed some formed almost 2 billion years ago – although the volcanic island is no more than 65 million years old.

So where did the grains come from? Torsvik thinks they are from fragments of continental crust beneath Mauritius that melted as the volcanic island formed. The team have named the proposed continent Mauritia.

It's a reasonable idea, says Michael Wysession at Washington University in St. Louis, Missouri. "It's hard to imagine how zircons could be there any other way."

Golf: Kuchar downs Mahan to win WGC Match Play crown

MARANA: Matt Kuchar denied Hunter Mahan a World Golf Championships Match Play Championship title repeat, triumphing over his fellow American 2 and 1 in Sunday's final at Dove Mountain.

Kuchar, eliminated by Mahan in the quarter-finals of the elite 64-man event last year, avenged that defeat as he prevented Mahan from joining Tiger Woods as the only back-to-back winners of the title.

Mahan was the first defending champion to return to the final since 2006 winner Geoff Ogilvy of Australia was runner-up in 2007.

Kuchar never trailed in the championship match, and in fact trailed for just three holes the entire week. The victory was his first in a WGC event and his fifth on the US PGA Tour.

Australian Jason Day was third, defeating former champion Ian Poulter of England in the consolation final 1-up.

Kuchar's triumph capped a wild week in the Arizona desert, where a snowstorm that halted first-round play on Wednesday was just the first surprise.

When the first round was finally completed on Thursday, the top two players in the world, Rory McIlroy and Tiger Woods, were on their way home, and the second round saw the next four seeds -- Luke Donald, Louis Oosthuizen and Justin Rose -- eliminated as well.

The delays, which also included some morning frost delays, made for long days. But after the third round and quarter-finals were contested on Saturday, Poulter was looking a good bet to challenge for the title.

But Poulter, whose match play credentials include an unblemished Ryder Cup singles record as well as a triumph in this event in 2010 and in the World Match Play Championship in Spain in 2011, fell to Mahan in the semi-finals on Sunday morning, when a biting wind made for tough going.

"It was tricky," the Englishman said. "It was a lot windier today. Hunter never gave me too many opportunities. A couple of chip shots weren't quite right, couple of bunker shots weren't quite right. I'm a bit disappointed I didn't press him more."

Mahan never trailed en route to a 4 and 3 victory over Poulter. He went 1-up at the second hole, and after Poulter squared the match with a par at the fourth, the American immediately regained the advantage with a birdie at the fifth and from there never relinquished the lead.

Kuchar rolled in a five-footer for birdie at the 15th to close out a 4 and 3 semi-final win over Day, who was unable to make his 22-footer to extend the match.

YouTube code refers to paid channel subscriptions

Paid channel subscriptions on YouTube may be closer than previously thought.

After reports last month that YouTube was considering offering channels that would require a fee to access, code has now appeared that suggests Google is already laying the software foundation for subscription channels.

According to Android Police, the latest version of YouTube for
Android includes two lines of code that refer to paid channel subscriptions. The code, apparently intended to generate messages on users' screens, say:

You can only subscribe to this paid channel on your computer.

You can only unsubscribe from this paid channel on your computer.

YouTube had approached a handful of producers about developing content for a subscription platform that might the Google-owned video-sharing site hoped to launch this year, according to an AdAge report in January. YouTube was also mulling a plan to charge for other items, such as entire libraries of videos, live events, and even self-help or financial advice shows, AdAge reported.

A paid content platform would offer viewers an alternative to traditional TV, as well as deliver new revenue streams through subscriptions and ads placed in the channels.

YouTube has floated the idea of launching subscription services in the past but has so far balked at the idea. YouTube CEO Salar Kamangar said in February 2012 that his company was considering allowing content providers to create their own, unique subscription-based video service on the site.

CNET has contacted YouTube for comment on the code and will update this report when we learn more.

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.
