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.

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.

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.

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.

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.

Lift-door stickers to drive home fire hazard message

SINGAPORE: The Singapore Civil Defence Force (SCDF) has unveiled lift-door stickers with fire safety messages as part of a campaign to generate greater public awareness on the dangers of discarding items at common areas such as corridors, lift lobbies, staircases and void decks.

One such sticker was unveiled by Senior Minister of State for Home Affairs and Foreign Affairs, Mr Masagos Zulkifli, at Blk 819, Tampines West Avenue 3 on Sunday.

The senior minister of state is also an MP for Tampines GRC.

Fires involving discarded items at common areas in HDB estates account for almost a quarter of the total number of residential fires in 2012.

SCDF says such fires have the potential to be more serious in nature due to the high fire load present and proximity to dwellings.

18 people were injured in 707 fires involving discarded items last year.

SCDF says leaving discarded items at the common areas, especially combustible items such as furniture and newspapers, can easily fuel fires when lighted materials such as cigarette butts are indiscriminately thrown onto them.

Cluttered common areas can also seriously hamper fire-fighting efforts, fire evacuation and conveyance of patients during a medical emergency.

I am here to share your pain, PM tells Hyderabad blast victims

HYDERABAD: Prime Minister Manmohan Singh visited the bomb blast sites in Hyderabad on Sunday and met some of the victims who are being treated in hospitals.

"I am here to share your pain and grief. We will take care of you," PM said to a vicitm Rajitha in Yashoda Hospital.

Talking to another victim, the PM said, "We will provide all possible medical help to you and others."

Consoling the mother of an injured at Omni Hospital, the PM said, "The staff will take all possible care of your son."

"I am here to stand in solidarity with the people of the city. We should maintain peace and calm," Manmohan Singh told the victims.

Elderly Abandoned at World's Largest Religious Festival

Every 12 years, the northern Indian city of Allahabad plays host to a vast gathering of Hindu pilgrims called the Maha Kumbh Mela. This year, Allahabad is expected to host an estimated 80 million pilgrims between January and March. (See Kumbh Mela: Pictures From the Hindu Holy Festival)

People come to Allahabad to wash away their sins in the sacred River Ganges. For many it's the realization of their life's goal, and they emerge feeling joyful and rejuvenated. But there is also a darker side to the world's largest religious gathering, as some take advantage of the swirling crowds to abandon elderly relatives.

"They wait for this Maha Kumbh because many people are there so nobody will know," said one human rights activist who has helped people in this predicament and who wished to remain anonymous. "Old people have become useless, they don't want to look after them, so they leave them and go."

Anshu Malviya, an Allahabad-based social worker, confirmed that both men and women have been abandoned during the religious event, though it has happened more often to elderly widows. Numbers are hard to come by, since many people genuinely become separated from their groups in the crowd, and those who have been abandoned may not admit it. But Malviya estimates that dozens of people are deliberately abandoned during a Maha Kumbh Mela, at a very rough guess.

To a foreigner, it seems puzzling that these people are not capable of finding their own way home. Malviya smiles. "If you were Indian," he said, "you wouldn't be puzzled. Often they have never left their homes. They are not educated, they don't work. A lot of the time they don't even know which district their village is in."

Once the crowd disperses and the volunteer-run lost-and-found camps that provide temporary respite have packed away their tents, the abandoned elderly may have the option of entering a government-run shelter. Conditions are notoriously bad in these homes, however, and many prefer to remain on the streets, begging. Some gravitate to other holy cities such as Varanasi or Vrindavan where, if they're lucky, they are taken in by temples or charity-funded shelters.

In these cities, they join a much larger population, predominantly women, whose families no longer wish to support them, and who have been brought there because, in the Hindu religion, to die in these holy cities is to achieve moksha or Nirvana. Mohini Giri, a Delhi-based campaigner for women's rights and former chair of India's National Commission for Women, estimates that there are 10,000 such women in Varanasi and 16,000 in Vrindavan.

But even these women are just the tip of the iceberg, says economist Jean Drèze of the University of Allahabad, who has campaigned on social issues in India since 1979. "For one woman who has been explicitly parked in Vrindavan or Varanasi, there are a thousand or ten thousand who are living next door to their sons and are as good as abandoned, literally kept on a starvation diet," he said.

According to the Hindu ideal, a woman should be looked after until the end of her life by her male relatives—with responsibility for her shifting from her father to her husband to her son. But Martha Chen, a lecturer in public policy at Harvard University who published a study of widows in India in 2001, found that the reality was often very different.

Chen's survey of 562 widows of different ages revealed that about half of them were supporting themselves in households that did not include an adult male—either living alone, or with young children or other single women. Many of those who did live with their families reported harassment or even violence.

According to Drèze, the situation hasn't changed since Chen's study, despite the economic growth that has taken place in India, because widows remain vulnerable due to their lack of education and employment. In 2010, the World Bank reported that only 29 percent of the Indian workforce was female. Moreover, despite changes in the law designed to protect women's rights to property, in practice sons predominantly inherit from their parents—leaving women eternally dependent on men. In a country where 37 percent of the population still lives below the poverty line, elderly dependent relatives fall low on many people's lists of priorities.

This bleak picture is all too familiar to Devshran Singh, who oversees the Durga Kund old people's home in Varanasi. People don't pay toward the upkeep of their relatives, he said, and they rarely visit. In one case, a doctor brought an old woman to Durga Kund claiming she had been abandoned. After he had gone, the woman revealed that the doctor was her son. "In modern life," said Singh, "people don't have time for their elderly."

Drèze is currently campaigning for pensions for the elderly, including widows. Giri is working to make more women aware of their rights. And most experts agree that education, which is increasingly accessible to girls in India, will help improve women's plight. "Education is a big force of social change," said Drèze. "There's no doubt about that."
