Motor Racing: Ecclestone wants Melbourne race for '50 years'

SYDNEY: Formula One ringmaster Bernie Ecclestone said Tuesday he would happily sign a contract for Melbourne to host the Grand Prix for 50 years, declaring "everybody loves Australia".

The sport has a contract with Melbourne until 2015 but beyond that it is up in the air, and other cities have expressed interest in snapping up the event which Ecclestone has previously said is the "least viable" on the F1 calendar.

Ecclestone said he hoped to travel to Melbourne for the season-opening 2013 race on March 17, in a year in which negotiations on a new contract are set to begin.

"Everybody loves Australia, loves Australian people and it's good to be there because it's the first race, it's nice, it's relaxed," he said in an official Australian Grand Prix podcast.

"We hope we're going to be in Melbourne forever, although I understand we do get a little bit of criticism and I don't know why.

"We're happy with Melbourne. I'd be happy to sign a 50-year contract. So we don't have a problem with Melbourne."

Ecclestone revealed that other Australian states had contacted him in attempts to poach the event from Victoria, but he indicated he was determined to keep the race in the southern state's capital.

"We get proposals from other parts, but we're happy in Melbourne," he said.

Ahead of the 2012 race Ecclestone floated the idea of a "divorce from our friends in Melbourne" and "walking away from Australia" when the contract expires.

"The race itself, from our point of view, is probably the least viable of all the races we have," he said then.

Ecclestone also said last year he was keen on a night race, which would fit better with European timezones, helping to sell TV rights there.

Such a move would likely be opposed by residents who live around Melbourne's Albert Park circuit, as well as costing the Victorian state government more to stage.

Last year's race cost taxpayers A$56.7 million (US$58.2 million) -- more than the revenue it generates -- with A$30 million of that reportedly going to Ecclestone for the right to host the race.

Ecclestone said the fee was "purely what the race cost" and included bringing six jumbo jets full of freight transportation to Australia.

Melbourne has hosted the Grand Prix since 1996.

'Copyright Alert System' rolls out to catch illegal downloaders

The "Copyright Alert System," aka "six strikes," kicked off today with the cooperation of five major Internet service providers. The goal of the new campaign is to curb copyright infringement by going after consumers rather than pirates.

While the CAS seems like something that would raise the hackles of privacy and civil liberty groups, the plan isn't to arrest, sue, or fine people downloading illegal movies, games, or music. Instead, the group managing the program -- the Center for Copyright Information -- says its objective is to "educate" such downloaders that they are infringing on protected intellectual copyrights.

"Implementation marks the culmination of many months of work on this groundbreaking and collaborative effort to curb online piracy and promote the lawful use of digital music, movies and TV shows," executive director for the Center for Copyright Information Jill Lesser wrote in a blog post today. "The CAS marks a new way to reach consumers who may be engaging in peer-to-peer (P2P) piracy."

The Center for Copyright Information is a joint venture between Hollywood copyright holders and ISPs -- it is also backed by the White House. AT&T, Cablevision, Verizon, Time Warner Cable, and Comcast are the participating ISP members in the venture.

The CAS has been in the works since 2011 and was scheduled to go into effect last November. But after a series of delays, including reluctance from ISPs and effects of Hurricane Sandy, the Center for Copyright Information postponed its launch until this year.

Under graduated response, or six strikes, entertainment companies will notify a participating ISP that a customer has allegedly been pirating movies or TV shows illegally. The bandwidth provider will then send a notice intended to educate the customer about the consequences of downloading unauthorized content.

The ISP is then supposed to gradually ratcheting up the pressure on customers who ignore the warnings. Eventually, after six warnings, ISPs can choose to suspend service. Graduated response, however, does not include the termination of service. Customers wrongly accused can appeal to their company and take their case to an arbitration group for review. The plan doesn't protect Internet consumers from being sued by copyright owners, however.

Some ways that pirated material is shared on the Internet, such as cyberlockers, e-mail attachments, and Dropbox folders, are not included under six strikes.

Here's more on the CAS from Lesser's blog post:

We hope this cooperative, multi-stakeholder approach will serve as a model for addressing important issues facing all who participate in the digital entertainment ecosystem. From content creators and owners to distributors to consumers, we all benefit from a better understanding of the choices available and the rights and responsibilities that come with using digital content, thereby helping to drive investment in content creation and innovative services that offer exciting ways to enjoy music, video and all digital content.

Over the course of the next several days our participating ISPs will begin rolling out the system. Practically speaking, this means our content partners will begin sending notices of alleged P2P copyright infringement to ISPs, and the ISPs will begin forwarding those notices in the form of Copyright Alerts to consumers. Most consumers will never receive Alerts under the program. Consumers whose accounts have been used to share copyrighted content over P2P networks illegally (or without authority) will receive Alerts that are meant to educate rather than punish, and direct them to legal alternatives. And for those consumers who believe they received Alerts in error, an easy to use process will be in place for them to seek independent review of the Alerts they received.

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 Claims Innocence on Death Penalty Charge

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.

Catching Up on the Trial? Check Out ABC News' Jodi Arias Trial Coverage

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."

Japan to nominate ADB president as BoJ chief

TOKYO: The Japanese government of Shinzo Abe is set to nominate Asian Development Bank president Haruhiko Kuroda as governor of the central bank, reports said on Monday, sending the dollar surging against the yen.

The greenback surged past 94 yen in early Asian trade from 93.37 yen in New York on Friday, with investors confident that there will be fresh aggressive easing steps by Abe's administration to boost the flagging economy.

The cabinet plans to submit his nomination to parliament this week, the Nikkei and other newspapers said. The appointment requires parliamentary approval.

If approved, the 68-year-old former finance ministry bureaucrat will succeed incumbent Bank of Japan (BoJ) governor Masaaki Shirakawa, who is stepping down on March 19, several weeks before the end of his term.

Abe has decided to pick Kuroda "as he backs Prime Minister Shinzo Abe's bold monetary easing policies while maintaining good links with the international financial industry," the Nikkei said.

Abe also plans to pick Tokyo's Gakushuin University economics professor Kikuo Iwata as one of the deputy governors, while BoJ executive-director Hiroshi Nakaso is the leading contender for the other deputy position, Nikkei reported.

Immediate confirmation of the reports was not available.

Abe told a news conference on Friday in Washington that his government would start picking nominees on Monday after concluding his US trip, during which he held talks with President Barack Obama.

Kuroda spent decades as a Japanese finance ministry bureaucrat. He was responsible for international affairs and foreign exchange policy between 1999 and 2003 before assuming the post of ADB president in 2005.

A former vice finance minister for international affairs, he is known as an advocate of aggressive monetary easing to overcome Japan's deflation, a stance in line with Abe's economic policy.

Abe had warned he could change a law guaranteeing the bank's independence if it did not follow his prescription of big spending and aggressive monetary easing to rescue the economy from decades of weak growth and deflation.

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.
