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.

Americans Targeted for Allegedly Running Underage Prostitution in Philippines

Arthur Benjamin is sitting at the edge of a small stage, wearing a lavender Hawaiian shirt and nursing a bottle of San Miguel Light beer. The 6-foot-6 mustachioed Texan lazily watches the half dozen or so girls dancing rather unenergetically around the stage's pole.

"I forgot your gift again, it's in the car," Benjamin says to one of the girls on stage, shouting above the pop music blaring from the speaker system.

The small, dingy bar, which Benjamin says he owns, is called Crow Bar. It's in a rundown part of the picturesque Subic Bay in the western Philippines, about a three hour drive from the capital, Manila. Home for 50 years to a United States naval base, Subic Bay has become synonymous with foreigners looking for sex in the long string of bars that line the main road along the coast.

Watch the full story on "Nightline" TONIGHT at 12:35 a.m. ET

The bars in this area are often packed with older foreign men ogling the young Filipina women available for the night for a "bar fine" of around 1,500 Filipino pesos, or just over $35. Many of the bars are owned and operated by Americans, often former military servicemen who either served on the base or whose ships docked here until the base was shuttered under political pressure in 1992.

Most of the prostitutes working in the bars are indeed 18 or older. But in the Philippines, just a small scratch to the surface can reveal a layer of young, underage girls who have mostly come from impoverished rural provinces to sell their bodies to help support their families.

Benjamin, 49, is, according to his own statements, one of the countless foreigners who has moved beyond just having sex with underage girls to owning and operating a bar where girls in scantily-clad outfits flaunt their bodies for patrons.

"My wife recently found out that I have this place," he tells an ABC News "Nightline" team, unaware they are journalists and recording the conversation on tiny hidden cameras disguised as shirt buttons.

Benjamin said that a "disgruntled waitress" had written his wife on Facebook, detailing his activities in Subic Bay.

"She sent her this thing saying that I have underage girls who stayed with me, that I [have anal sex with them], I own a bar, I've got other girls that I'm putting through high school, all this other crap," he said.

"All of which is true," he laughed. "However, I have to deny."

He sends a text message summoning his current girlfriend, a petite dark-skinned girl called Jade, who he said is just 16 years old. Benjamin says he bought the bar for her about a year ago and while most still call it Crow Bar, he officially re-named it with her last name.

"She needed a place to stay, I needed a place to do her. I bought a bar for her," he says, explaining that she lives in a house out back by the beach.

"You're not going to find anything like this in the States, not as a guy my age," he said as he looked down at Jade. "Ain't going to happen."

Benjamin is the latest target of Father Shay Cullen, a Catholic priest with a thick Irish brogue and fluency in the local language, Tagalog. Through his non-profit center called Preda, he's been crusading against underage sex trafficking in the Philippines for 40 years.

White House releases state-by-state breakdown of sequester’s effects

The White House on Sunday detailed how the deep spending cuts set to begin this week would affect programs in every state and the District, as President Obama launched a last-ditch effort to pressure congressional Republicans to compromise on a way to stop the across-the-board cuts.

But while Republicans and Democrats were set to introduce dueling legislative proposals this week to avert the Friday start of the spending cuts, known as the sequester, neither side expected the measures to get enough support to pass Congress.

Lawmakers instead were planning for a lengthy round of political jostling ahead of another budget showdown in late March that could determine whether the $85 billion in cuts to domestic and defense spending this fiscal year stick.

Republicans questioned whether the sequester would be as harmful as the White House predicted and worked on a proposal that could preserve the cuts while giving the administration more discretion to choose how to implement them. Democrats expressed worry that they might be forced to accept the cuts if the public outcry is not loud enough in coming weeks.

Seeking to raise alarm among a public that has not paid much attention to the issue, the White House on Sunday released 51 fact sheets describing what would happen over the next seven months if the cuts go into effect.

The Washington area would be hit hard. Virginia, Maryland and the District cumulatively would lose $29 million in elementary and high school funding, putting at risk 390 teacher and teacher-aide jobs and affecting 27,000 students. About 2,000 poor children would lose access to early education. In the area of public health, less funding would mean 31,400 fewer HIV tests.

And nearly 150,000 civilian Defense Department personnel in the area would be partially furloughed through Sept. 30 — with a total average reduction in pay of $7,500. (Defense Department officials previously explained that the furloughs would probably come in the form of workers being asked to take one day off per week, amounting to a 20 percent cut in pay.)

Obama is planning to go to Newport News on Tuesday to highlight the impact of cuts.

The sequester — worth $1.2 trillion over 10 years — effectively orders the administration to make across-the-board, indiscriminate cuts to agency programs, sparing only some mandatory programs such as Medicaid and food stamps. It is the result of a 2011 deal forged by the White House and Congress to reduce federal borrowing. It was intended as a draconian measure so blunt that it would force lawmakers to find alternative means of reducing the budget deficit. But while Republicans and Democrats have both made suggestions for how to do so, no plan has gotten enough support to pass Congress.

On Sunday, White House officials painted an ominous picture of cuts affecting a wide range of government services if the sequester takes effect — and spotlighted the impact in states that are politically important to Republicans.

Hundreds of teachers could lose their jobs in Ohio, home to House Speaker John A. Boehner (R), officials said, and thousands of children may not get necessary vaccines in conservative Georgia.

Swimming: Magnussen reveals sleeping tabs 'tradition'

SYDNEY: World 100m freestyle champion James Magnussen -- who led the much-vaunted 4x100m Australian relay team which bombed spectacularly at the 2012 Olympics -- has claimed taking sleeping tablets was "a tradition".

The team last week admitted taking the prescription drug Stilnox, banned by the Australian Olympic Committee (AOC), as part of a "bonding exercise" ahead of the Games in London, where they failed even to reach the podium.

Five of the six team members took one of the sleeping tablets at a staging camp in Manchester after seeing a movie and going to dinner in a bid to build unity in the fiercely competitive team.

In an interview with Channel Seven aired late Sunday, Magnussen said during dinner that the discussion had turned to what previous relay teams had done to bond and the group had collectively decided to take the drug.

"The tradition had been, and what we did, was take Stilnox on its own with water," he said.

"We then sat around telling jokes, you know laughing, carrying on. It was really, I think, for a lot of us a chance to take a step back from the pressure."

Australian swimmers had previously used Stilnox to ensure a good night's rest before competition until the AOC banned it in the lead-up to London.

But use of the drug had been discouraged as far back as 2005, according to The Australian newspaper, which said former relay swimmers Michael Klim, Ashley Callus and Andrew Lauterstein had all denied taking it as a bonding tradition.

Recreational users of Stilnox often deliberately try to stay awake, which can induce a "high" and even cause hallucinations.

Magnussen, 21, denied he was out of control on the night when the team engaged in misbehaviour including door-knocking and prank-calling teammates but said he would not be repeating the incident.

The swimmer said he had learned "a lot about the repercussions of my behaviour" and admitted to being too arrogant before the Games.

"It has taken me a lot of reflection and a lot of time to admit that," he said. "But again I was inexperienced and I didn't know how big of a deal and how big of an event the Olympics was and how much of a part it was going to play mentally, and I didn't cope with it."

London was Australian swimming's first Games without an individual gold medal since the 1976 Montreal Olympics and marked Australia's lowest medal haul in the sport since Barcelona in 1992 with just one gold, six silver and three bronze.

Two reports into what went wrong in London found the squad lacked leadership and that "toxic" incidents such as drunkenness and bullying had gone unchecked.

Pranab Mukherjee to witness PSLV-C20 launch from Sriharikota today

CHENNAI: President Pranab Mukherjee is expected to witness the launching of the Indo-French satellite 'SARAL', aimed at oceanographic studies, and six other foreign mini and micro satellites from Isro's workhorse rocket PSLV from the Sriharikota spaceport today.

The Polar Satellite Launch Vehicle (PSLV-C20) is slated for blast-off at 5.56pm from the first launch pad of Satish Dhawan Space Centre, 110 kms from here.

This is the 23rd mission of PSLV. It has an impeccable record of 21 consecutive successful flights. This is the ninth time ISRO is using the 'core alone' variant of the rocket.

The 668.5 kgs and 44.4 metres tall rocket will have a lift off mass of 229.7 tonnes. Besides SARAL, it would put into orbit two micro-satellites UniBRITE and BRITE from Austria and AAUSAT3 from Denmark and STRAND from United Kingdom as also one micro-satellite (NEOSSat) and one mini-satellite (SAPPHIRE) from Canada.

ISRO had initially planned to launch SARAL on December 12 last year, but postponed it to carry out additional tests to "address technical issues to ensure reliability".

The ISRO-built SARAL is a 410-kg satellite with payloads-Argos and Altika-from French space agency CNES for study of ocean parameters towards enhancing the understanding of the ocean state conditions which are otherwise not covered by the in-situ measurements.

In view of the President's presenc, the Satish Dhawan Space Centre has been put under a thick net of security, officials said.

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 Stephen 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.

Jennifer Lewis 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.

"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 Stephen 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."

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.

Quentin 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.

Obama’s new political group to lure unlimited donations

In close consultation with President Obama, two of his top political strategists are designing an ambitious new organization funded by donations from wealthy individuals and corporations aimed at making political and legislative gains at the federal and state levels.

The fledgling Organizing for Action says it will be nonpartisan and steer clear of election activity. But the line between issue disputes and electoral politics can be a fuzzy one. The first of an expected wave of ads on gun control, for example, has targeted only Republicans. And OFA board member Jim Messina, who managed Obama’s reelection campaign, has been talking with Democratic Party leaders, including those responsible for success in the 2014 midterm elections.

Over the past month, Messina and Jon Carson, a leading strategist, have traveled the country meeting with members of the Obama 2012 National Finance Committee, who are being pressed back to work to find support for the new organization.

In huddles with Hollywood studio executives, California energy investors and Chicago business titans, they have suggested $500,000 as a target level for OFA bundlers and that top donors get invitations to quarterly OFA board meetings attended by the president.

The next step in converting Obama’s election apparatus to grass-roots lobbying is a “founders summit” March 13 that includes a $50,000-per-person meeting at the Jefferson hotel in Washington led by Messina and Carson. Those planning to attend said they hope the president will be part of the day’s agenda, though the White House and OFA declined to comment on that possibility.

A one-page memo accompanying the invitation lays out the goals of the new OFA: Building grass-roots support for Obama proposals on issues ranging from climate change to immigration reform to women’s health.

In addition, the memo says, the OFA will help “strengthen the progressive movement and train our next generation of leaders.”

It also promises to engage in “state-by-state fights” over issues such as “ballot access and marriage equality.”

Advocates for campaign finance reform see the organization’s goal of raising tens of millions of dollars as a new channel to allow wealthy individuals and corporations to seek favors from the administration. And they criticize Obama for abandoning reform rhetoric in favor of a group that can raise unlimited sums with limited transparency, the very circumstances he complained about publicly in 2010 when the Supreme Court granted corporations and unions the opportunity to contribute to groups seeking to influence elections.

Unlike political parties and other organizations set up to win elections, the OFA is not subject to federal election fundraising restrictions and disclosure requirements, meaning the public will have only limited opportunities to learn about its operations, including how revenue is collected and spent.

OFA officials say they have adopted a voluntary disclosure system that goes beyond that required by law and that will provide sufficient public review.

China gold output up nearly 12% in 2012: report

SHANGHAI: Gold production in China, the world's second largest market for the precious metal, surged nearly 12 percent year-on-year last year despite a slowdown in the domestic economy, state media reported.

Output rose to 403.1 tonnes in 2012, up 11.66 percent from 2011, the official Xinhua news agency said late Saturday, quoting figures from the Ministry of Industry and Information Technology.

China is the world's second largest consumer of gold after India. A global industry group, the World Gold Council, has put China's consumer demand for gold at 776.1 tonnes last year, flat from 2011.

The council attributed the stable Chinese demand to a slowdown in the domestic economy and consolidation in gold prices which discouraged investors, according to its latest report released this month.

China's economy -- the world's second largest -- grew at its slowest pace in 13 years in 2012, expanding 7.8 percent from the year before.

But the economy has been showing renewed vigour since late last year, with growth accelerating in the final three months of 2012 to 7.9 percent, snapping seven straight quarters of weakening expansion.

"The signs of economic improvement bode well for gold demand in China, although the indications are for a steady firming of demand rather than for strong growth," the World Gold Council said.

China's Ministry of Industry said domestic gold prices dropped in December last year as worries over the US "fiscal cliff" caused uncertainty.

US lawmakers clinched a last-gasp deal to avoid the fiscal cliff of tax hikes and spending cuts.

China's gold producers recorded a combined 35 billion yuan (US$5.6 billion) in profits last year, up just 4.0 percent from 2011, the ministry said.

19 swine flu cases reported in Himachal

SHIMLA: Swine flu (H1N1) continues to spread in Himachal Pradesh with 19 cases reported this year, an official said on Sunday. Two people have died of the disease this year in this hill state.

At Shimla's Indira Gandhi Medical College and Hospital (IGMCH), 102 patients with symptoms of swine flu were reported from across the state, a health official told IANS.

He said both the people who died had been admitted at IGMCH.

Eight positive cases have been reported from Kangra, the state's largest district, five from Solan, four from Shimla, and one each from Una and Sirmaur districts.

The official said isolation wards have been set up at medical colleges and district hospitals.

Detection of new cases is being done at the places from where H1N1 cases have been reported, he added.
