The fish with a rainbow eye

These eyes are positively spectral. They belong to a Caribbean trumpetfish, and their many colours are created by the refraction of light.

Rays of light bend as they pass in and out of the fish's eyes, and different colours of light bend different amounts. As a result, what was previously white light splinters into bands of different colours, like a rainbow. From bottom to top in the photo, the colours in the eye follow part of the usual rainbow sequence, from orange to blue.

Like all trumpetfish, Aulostomus maculatus has a long thin body rather like that of an eel. It often swims vertically, disguising itself among vertical corals. But it also camouflages itself by swimming along the lateral lines of larger fish.

The photograph, by Randall Benton, has just won third prize in the Nature category of the World Press Photo of the Year awards 2012.

Iberia strikers clash with police at Madrid airport

MADRID: Strikers at Spanish airline Iberia clashed with police at Madrid-Barajas airport on Monday as they launched a five-day action against job cuts.

Thousands of strikers tried to force their way into one of the terminals at the airport before being pushed back by police, an AFP reporter at the scene said.

After several charges by police armed with batons, the Iberia staff finally entered the terminal where they carried on a protest during the strike action, which led to hundreds of flight cancellations.

Iberia's cabin crew, ground staff and maintenance workers were striking from Monday to Friday in the first of a series of three five-day strikes to protest plans to axe 3,800 jobs.

The flag carrier said it scrapped 415 flights across Spain and Europe for the week including 81 on Monday alone. The airline said it expected to operate 135 flights on Monday.

Iberia's offshoots were hard hit. Iberia Express chopped 20 flights on Monday alone and regional carrier Air Nostrum cut another 57.

Iberia ground crew service flights for budget carrier Vueling, forcing that airline, also, to curb operations.

Vueling said it had cut 354 flights for the five days - 39 percent of its usual service. A list posted on the airline's web site showed 78 cancellations for Monday alone.

Iberia workers also plan to strike from March 4-8 and again from March 18-22 to protest against the job cuts announced by International Airlines Group (IAG), which owns Iberia and British Airways.

IAG announced last week that it would axe 3,800 jobs at Iberia to save costs but said it was still open to talks with unions during a formal 30-day consultation process.

Iberia executives say the airline accumulated 850 million euros ($1.1 billion) in losses between 2008 and September 2012.

The airline aims to cut its capacity by 15 percent this year, eliminating some loss-making routes to Latin America and trimming its fleet by 25 aircraft, including five long-haul jets

Iberia said there were no significant incidents during the first day of the strike action, with 85 percent of passengers already put on other flights and the other 15 percent reimbursed.

After some earlier teasing, LG Electronics fully detailed its Optimus G Pro Android phone today, a high-end model with 5.5-inch screen, LTE networking, and a quad-core 1.7GHz processor.

LG often sells its phones first in its home market of South Korea, and it looks like that's the plan for the Optimus G Pro, too. But it'll arrive in other areas, too, including North America and Japan in the second quarter of 2013, LG said in an announcement a week ahead of the Mobile World Congress show. That's where the South Korean company will show off the phone and announced three lower-end L-series Android phones, the Optimus L7 II, L5 II, and L3 II.

The Optimus G Pro is a large-screen model that
Android smartphone makers such as HTC and Samsung have embraced in an effort to differentiate products from the smaller iPhone. The Optimus Pro G has a 5.5-inch, 1920x1080-pixel AMOLED screen with a linear resolution of 400 pixels per inch.

Combined with its relatively large 3,140mAh battery, that means people can watch Full HD video "for hours on end," LG said.

The processor is the quad-core 1.7GHz Qualcomm Snapdragon 600, and the phone comes with 2GB of RAM. The phone itself measure 150.2x76.1x9.4mm

The camera has a 13-megapixel rear-facing camera with an LED flash and a 2.1MP front-facing camera. A feature called VR Panorama will construct 360-degree panoramas out of an array of horizontal and vertical views around the person holding the phone.

Both of the phones' cameras can be used in a dual-recording mode that "allows users to capture video with both the front and rear cameras simultaneously for a unique picture-in-picture experience," LG said.

Meet the Meteorite Hunter

Michael Farmer is one of the world's only full-time meteorite hunters. Since the 1990s, the 40-year-old Tucson, Arizona, resident has been scouring the world for pieces of interstellar rock, racing to be the first one on the scene and selling his finds to museums and private collectors. On Friday, as Russians reportedly scrambled to collect fragments from a passing meteorite that injured hundreds, Farmer spoke with National Geographic about his unusual line of work.

Why are so many people in Russia busy gathering up meteorite fragments?

It's a historic event. This will be talked about forever. Everyone wants to have a little piece of it. And scientifically, we want to study it. We want to know what's out there, and we want to know how big it is, and we want to know what damage it can cause. The preliminary data from NASA's Jet Propulsion Laboratory says about 7,000 tons landed.

How many meteorite fragments are known to be on Earth?

There are a couple of hundred thousand known meteorites. Of course, there's millions and millions on the planet; we just have to find them. Most of the Earth is inhospitable—heavy forest, jungle, ocean. Meteorites that fall in the ocean are just gone, disappeared to the bottom.

How many other full-time meteorite hunters are there?

Dedicated, serious meteorite hunters? There are maybe 20 of us. If you add in the part-timers who go somewhere whenever [an impact is] close to them, then you might approach a hundred.

How did you become a meteorite hunter?

Here in Tucson right now we have the world's biggest mineral show going on. I bought a meteorite at this very same show 20 years ago, and I was absolutely obsessed and hooked. Since then I've been around the world more times than I can count—four million miles on American Airlines alone.

How many countries have you been to?

About 70 countries, by my last count. About 50, 59 trips to Africa—a lot of work in Africa. The Sahara and other deserts there make meteorites easier to find than on other terrains, and also keep them well preserved.

What are the challenges you face when you're on a hunt?

Well, you're usually going into a kind of chaotic scene where nobody really knows much. In Africa and other places I go [the locals] don't usually understand what's happening, and most of the time they don't care. They're more concerned with eating that day. But the instant some guy shows up and says, "I'll pay you to find this rock," the whole village empties—and then lots of rocks show up.

It can be dangerous work. I've been robbed, put into prison. For example, I was in prison two years ago in the Middle East, in Oman—actually sentenced, convicted, and put in prison for three months for "illegal mining activity." Not a very nice time. And the same year, 2011, in the fall I went to Kenya three times, after a major meteorite fell. On the third trip over I had a robbery where they ambushed us and almost murdered me. I was down on my knees, with a bag over my head and a machete on my throat and a gun at my head, being beaten. Luckily they decided to just take everything and leave instead of killing us. It's a dangerous line of work because it involves money, and people want that money.

What's the most valuable meteorite you've found?

Well, I've found three separate moon rocks in the Middle East. [Moon rocks are considered a type of meteorite that came loose from the lunar surface and fell to Earth.] And one of them I sold for $100,000 a week later. It was just a small piece—the size of a walnut. But the best meteorite I found was with my three partners up in Canada. It was actually discovered in 1931, but we went back to the location and discovered 53 kilograms [117 pounds] more. It's an extremely rare type of meteorite called a pallasite, and it's about 4.5 billion years old. We sold it to the Canadian government for just under a million dollars. Now it's in the Royal Ontario Museum, in Toronto, and it's considered a national treasure.

Where else do you sell your wares?

Well, I do shows around the world, in France, Germany, Japan. I go to expos, like this one here in Tucson, which is the biggest mineral show in the world and lasts for three weeks. And museums are always calling me.

It's a small market. It's not like I need a shop or anything. People call me or email me or go to my website and check it out. The market these days is so ravenous for anything new that when I get a new meteorite, it's usually sold in hours. I don't even have to work anymore. I just make phone calls to a few people, and it's all gone.

Where do you store your collection?

I have multiple storage sites—never put all your eggs in one basket. And I have lots of bulk material. Sometimes I buy this stuff by the ton, and it goes into storage and I sell it off one piece at a time.

What's the verification process like?

Any meteorite, anything that we want to have an official name, has to go to a laboratory, where it gets sectioned and studied by scientists. For example, I'd guess this meteorite in Russia yesterday will be in a lab in Moscow, being researched within hours.

Related: History's Big Meteorite Crashes

In the collector market, we work collaboratively with the scientists. I supply them with rocks, and they supply me with data, both of which I need to make money. People want to know what something is before they buy it.

Are there legal or ethical implications to meteorite hunting?

There always are. Certain countries have passed laws. But when I was arrested in Oman, they actually had no law—they were just very upset that we were taking lots of meteorites. The only law they could charge us with was illegal mining operations—basically running a company in the country without government licensing. But I won on appeal because we had no mining equipment. We were picking up rocks off the surface of the desert. And a judge said, "If a child could do it, then it's not mining." And I was immediately released and sent home.

But there's always friction between the collecting market and the scientific market. There are scientists out there who believe that no meteorite should be in private hands. Well, I tell you, I've been on hunts all over the world and I've only run into scientists a couple of times. They don't have the time or money to do it. So if it wasn't for us, 99 percent of these meteorites would be lost to science.

What about this meteorite strike—do you think scientists will go to Russia?

I guarantee there'll be scientists from everywhere in the world going to this one.

Are you catching the next flight to Moscow?

Well, of course as a meteorite dealer, I want to own this. I woke up this morning to a hundred e-mails from people begging me to get on a plane and go get it so they can buy a piece.

But I'm probably not going. Getting into Russia can be complicated. I'll just buy some from the Russians when it comes out.

Of course, if this had happened in China or somewhere in Africa, I'd be packing my bags right now and getting on a plane, figuring it all out when I get there.

Country Singer Mindy McCready Dead at 37

Mindy McCready, the country singer who soared to the top of the charts with her debut album, "Ten Thousand Angels," but struggled with substance abuse, served time in jail and fought a lengthy battle with her mother over custody of her son has died of what appears to be a self-inflicted gunshot wound, police said. She was 37.

Deputies from the Cleburne County Sheriff's Office were dispatched to a report of gun shots fired at McCready's Heber Springs, Ark., home at around 3:30 p.m. today.

There they found McCready on the front porch. She was pronounced dead at the scene from what appeared to be a single self-inflicted gunshot wound, according to a statement from the sheriff's office.

PHOTOS: In Memoriam 2013

McCready's boyfriend, David Wilson, died in January of a self-inflicted gunshot wound. McCready was ordered to enter rehab shortly after Wilson's death, and her two children, Zander, 6, and 9-month-old Zayne were taken from her. She was released after one day to undergo outpatient care.

McCready scored a number-one Billboard country hit in 1996 with "Guys Do It All the Time," but in recent years, the country crooner has received more media attention for her troubled personal life than her music.

She has been arrested multiple times on drug charges and probation violations and has been hospitalized for overdoses several times, including in 2010, when she was found unconscious at her mother's home after taking a painkiller and muscle relaxant.

Her mother, Gayle Inge, was appointed to be her son Zander's legal guardian in 2007 after McCready was arrested for violating probation on a drug-related charge. The boy's father is McCready's ex-boyfriend Billy McKnight.

Following a custody hearing in May 2011, McCready released a statement, saying, "We have progressed in a positive manner to reunite me and my son, Zander. I feel very optimistic this will happen in the near future."

But just six months later, in November 2011, was accused of violating a court order for failing to bring Zander back to her mother in Florida after a visit. The boy was placed in foster care while McCready and her mother worked out the custody dispute.

McCready's struggle with substance abuse was broadcast in 2010 on the third season of "Celebrity Rehab with Dr. Drew."

McCready also claimed to have carried on a decade-long affair with baseball star Roger Clemens that began was she was 15 years old and he was 28. Clemens denied that the relationship was sexual in nature.

"You know what, I don't think I'm ever going to be one of those people that has a normal, quiet existence," McCready told ABC Radio in 2010. "I've been chosen for some reason to be bigger and larger than life in every way. Negative and positive."

McCready, who was born and raised in southern Florida, moved to Nashville when she was 18 to start her music career.

Within a few months, she was starting to work with producer David Malloy, who got her tapes to RLG Records. The company signed her to a contract after seeing her in concert, giving her a record deal less than a year after her arrival in Nashville.

Her debut album, "Ten Thousand Angels," went gold within six months of its release in April 1996, and eventually went multi-platinum. Two more followed: "If I Don't Stay the Night," in 1997; and "I'm Not So Tough" in 1999.

Her most recent album, "I'm Still Here," featuring new versions of her early hits "Ten Thousand Angels" and "Guys Do It All the Time," was released in March 2010.

False memories prime immune system for future attacks

IN A police line-up, a falsely remembered face is a big problem. But for the body's police force – the immune system – false memories could be a crucial weapon.

When a new bacterium or virus invades the body, the immune system mounts an attack by sending in white blood cells called T-cells that are tailored to the molecular structure of that invader. Defeating the infection can take several weeks. However, once victorious, some T-cells stick around, turning into memory cells that remember the invader, reducing the time taken to kill it the next time it turns up.

Conventional thinking has it that memory cells for a particular microbe only form in response to an infection. "The dogma is that you need to be exposed," says Mark Davis of Stanford University in California, but now he and his colleagues have shown that this is not always the case.

The team took 26 samples from the Stanford Blood Center. All 26 people had been screened for diseases and had never been infected with HIV, herpes simplex virus or cytomegalovirus. Despite this, Davis's team found that all the samples contained T-cells tailored to these viruses, and an average of 50 per cent of these cells were memory cells.

The idea that T-cells don't need to be exposed to the pathogen "is paradigm shifting," says Philip Ashton-Rickardt of Imperial College London, who was not involved in the study. "Not only do they have capacity to remember, they seem to have seen a virus when they haven't."

So how are these false memories created? To a T-cell, each virus is "just a collection of peptides", says Davis. And so different microbes could have structures that are similar enough to confuse the T-cells.

To test this idea, the researchers vaccinated two people with an H1N1 strain of influenza and found that this also stimulated the T-cells to react to two bacteria with a similar peptide structure. Exposing the samples from the blood bank to peptide sequences from certain gut and soil bacteria and a species of ocean algae resulted in an immune response to HIV (Immunology, doi.org/kgg).

The finding could explain why vaccinating children against measles seems to improve mortality rates from other diseases. It also raises the possibility of creating a database of cross-reactive microbes to find new vaccination strategies. "We need to start exploring case by case," says Davis.

"You could find innocuous pathogens that are good at vaccinating against nasty ones," says Ashton-Rickardt. The idea of cross-reactivity is as old as immunology, he says. But he is excited about the potential for finding unexpected correlations. "Who could have predicted that HIV was related to an ocean algae?" he says. "No one's going to make that up!"

More youths doing volunteer work in North West District

SINGAPORE: More youths have stepped up to do volunteer work in Singapore's North West District. Last year, the number more than doubled, from about 470 to some 1,000.

Volunteers' Night was held on Sunday evening to show appreciation to those who have helped.

Members of Parliament from Holland-Bukit Timah GRC were present to show their support.

This year, the district aims to boost the number of volunteers of all ages from the current 2,880 to 4,000.

Programmes to assist the needy and bond residents will be beefed up, with a focus on building a caring and healthy community.

Mayor of North West District Dr Teo Ho Pin said: "We'll be engaging a lot of volunteers, especially from companies and the community to come forward to help our needy families, especially (those living in) rental blocks, so we're expecting about maybe 500, 600, or even 800 volunteers in that area."

The district had 1,250 volunteers across various age groups in 2011, which doubled in the following year.

Russian meteorite: The conspiracy theories

A strange time for a military attack?

(Credit:
CNN; screenshot by Chris Matyszczyk/CNET)

A good hearty conspiracy theory can shine a sharp light on two of humanity's most enduring traits.

One, of course, is humanity's boundless imagination. The other is humanity's essential suspicion of humanity.

So while you might be deeply immersed in Bill Nye's explanation of the Russian meteorite, those with darker sensibilities have filled the Web with their fears and hauntings about the phenomenon.

There are few nations with greater awareness of dark sensibilities than Russia. The fact that there seems to be little evidence of meteorite fragments on the ground has encouraged some Russians to offer their own suspicions.

As the Toronto Globe and Mail reports, nationalist leader Vladimir Zhirinovsky hasn't been slow to offer something of a Hot War perspective.

"It's not meteors falling. It's a new weapon being tested by the Americans," he was quoted as saying.

We know from our recent experience of North Korea that weapons testing is an imprecise science.

But if you were an American in the mood to test a weapon, would Chelyabinsk, Russia, be your very first choice of place for the experiment?

Perhaps Tallahassee; Area 51; and Bialystok, Poland, were all unavailable due to prior commitments. Or perhaps it wasn't the Americans, but, say, the North Koreans, who mistook Chelyabinsk for, say, Chelsea.

Zhirinovsky's rather emotionally manipulative offering was countered by Russia's Emergency Ministry, which dedicated itself to an extensive rebuttal of his belief (and that of others) that this was some sort of military thing. The rebuttal? "Rubbish."

But that wasn't going to put off the local media, was it? Not only do they have papers to sell, they also have theories to expound to a troubled nation and world.

So, as The Atlantic reports, the local Znak newspaper accepted that this was a meteorite but insisted the explosion was caused by military defense blowing it up.

More Technically Incorrect

Yes, of course it has a source in the military. You thought it didn't?

Though I've watched a few movies in which exciting things happen, I don't find it easy to imagine that some sort of terrestrially created missile-laden aircraft could really explode a meteorite in such a manner.

It is easier to imagine, though, that politicians like Zhirinovsky might take the opportunity to foment a little rage.

Indeed, Alex Jones' infamously well-guarded Infowars site offered that Zhirinovsky insisted that America -- in the person of Secretary of State John Kerry -- had tried to give Russia advance notice of its "attack."

The Drudge Report led me to a piece at Foreign Policy that explained that Sergey Lavrov, Russia's foreign minister, simply hadn't called Kerry back.

Which all suggests that Russia isn't, after all, living in fear of an attack from the U.S. Especially one over Chelyabinsk.

On balance, I prefer to currently believe Nye. He is the science guy, after all. And science guys know scientific events when they see them.

I hope.

Picture Archive: Making Mount Rushmore, 1935-1941

Photograph from Rapid City Chamber of Commerce/National Geographic

There's no such thing as Presidents' Day.

According to United States federal government code, the holiday is named Washington's Birthday, and has been since it went nationwide in 1885.

But common practice is more inclusive. The holiday expanded to add in other U.S. presidents in the 1960s, and the moniker Presidents' Day became popular in the 1980s and stuck. It may be that George Washington (b. February 22, 1732) andAbraham Lincoln (b. February 12, 1809) still get the lion's share of attention—and appear in all the retail sale ads—on the third Monday in February, but the popular idea is that all 44 presidents get feted.

Mount Rushmore is a lot like that one day a year writ large—and in granite. It's carved 60 feet (18 meters) tall and 185 feet (56 meters) wide, from Washington's right ear to Lincoln's left.

The monument's sculptor, Gutzon Borglum, grew up in Idaho, a first-generation American born to Danish parents. He studied art in France and became good friends with Auguste Rodin. Borglum mostly worked in bronze, but in the early 1910s he was hired to carve the likenesses of Confederate leaders into Stone Mountain in Georgia.

He was about to be fired from that job for creative differences about the same time that a South Dakota historian named Doane Robinson had an idea. Robinson wanted to have a monument carved into the Black Hills of South Dakota, maybe Western historical figures like Chief Red Cloud and Lewis and Clark, each on their own granite spire. (Plan a road trip in the Black Hills.)

Robinson hired Borglum and gave him carte blanche. Borglum was looking for something with national appeal, so he chose to depict four presidents: George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln.

Borglum wanted to represent the first 150 years of the nation's history, choosing four presidents as symbols of their respective time periods. He took a tour of western South Dakota, searching for an ideal canvas.

The sculptor was looking for three things: a surface strong enough to sculpt, a mountain big enough to hold several figures, and a mountain face that received morning sunlight. Mount Rushmore fit the bill and was already part of a national forest, so it was easy to set aside as a national memorial.

Work started in 1927. Calvin Coolidge attended the dedication ceremony. It took 14 years to finish the carving, conducted mostly in summertime because of the area's harsh winters.

There were approximately 30 workers on the mountain at any give time. In total about 400 had worked on it by the time the monument was finished. Though the project involved thousands of pounds of dynamite and perilous climbs, not a single person died during the work.

Borglum himself died of natural causes in 1941, though, just six months before the project was declared "closed as is" by Congress that Halloween. His son Lincoln—named for his father's favorite president—took over.

In the photo above, a worker refines the details of Washington's left nostril.

About 90 percent of the mountain was carved using dynamite, which could get within 3 to 5 inches (8 to 13 centimeters) of the final facial features. For those last few inches, workers used what was known as the honeycomb method: Jackhammer workers pounded a series of three-inch-deep holes followed up by chiselers who knocked off the honeycomb pieces to get the final shape. Then carvers smoothed the "skin's" surface.

Gun Ban Would Protect More Than 2,200 Firearms

Congress' latest crack at a new assault weapons ban would protect more than 2,200 specific firearms, including a semi-automatic rifle that is nearly identical to one of the guns used in the bloodiest shootout in FBI history.

One model of that firearm, the Ruger .223 caliber Mini-14, is on the proposed list to be banned, while a different model of the same gun is on a list of exempted firearms in legislation the Senate is considering. The gun that would be protected from the ban has fixed physical features and can't be folded to be more compact. Yet the two firearms are equally deadly.

"What a joke," said former FBI agent John Hanlon, who survived the 1986 shootout in Miami. He was shot in the head, hand, groin and hip with a Ruger Mini-14 that had a folding stock. Two FBI agents died and five others were wounded.

Hanlon recalled lying on the street as brass bullet casings showered on him. He thought the shooter had an automatic weapon.

Both models of the Ruger Mini-14 specified in the proposed bill can take detachable magazines that hold dozens of rounds of ammunition. "I can't imagine what the difference is," Hanlon said.

President Barack Obama has called for restoring a ban on military-style assault weapons and limiting the size of ammunition magazines.

Gun Owners Rally State Capitals Across Country Watch Video

A bill introduced last month by Sen. Dianne Feinstein, D-Calif. would ban 157 specific firearms designed for military and law enforcement use and exempt others made for hunting purposes. It also would ban ammunition magazines that hold more than 10 rounds.

Yet there are firearms that would be protected under Feinstein's proposal that can take large capacity magazines like the ones used in mass shootings that enable a gunman to fire dozens of rounds of ammunition without reloading.

Feinstein said in a written response to questions from The Associated Press that the list of more than 2,200 exempted firearms was designed to "make crystal clear" that the bill would not affect hunting and sporting weapons.

The December shooting at an elementary school in Newtown, Conn., that left 26 students and educators dead forced Washington to focus on curbing gun violence, a risky political move not tried in decades.

The gun industry, which is fighting any sort of ban, says gun ownership in the U.S. is the highest it's ever been, with more than 100 million firearms owners.

Obama and Vice President Joseph Biden have traveled around the country in an effort to gain support for new laws. Feinstein's proposal is the only sweeping piece of legislation designed to ban assault weapons currently being considered.

But some gun experts say the lists of banned and exempted firearms show a lack of understanding and expertise of guns.

"There's no logic to it," said Greg Danas, president of a Massachusetts-based expert witness business and firearms ballistic laboratory. "What kind of effect is it going to have?"

Feinstein's bill defines an assault weapon as a semi-automatic firearm with a detachable magazine that has one of several military characteristics that are specified in her legislation. Examples of those characteristics include a pistol grip, which makes a firearm easier to hold, and a forward grip, which makes the firearm easier to stabilize to improve accuracy. The definition is similar to the one in Congress' original ban on assault weapons, which went into effect in 1994 and was widely criticized for outlawing firearms based on cosmetic features.
