How Does the Mona Lisa Look Without Mona Lisa?

Recognize this 77 x 54-centimeter oil on canvas painting? Believe it or not, it's perhaps the best-known Leonardo da Vinci painting this side of The Last Supper.

Yes, it's the Mona Lisa without Mona Lisa, as interpreted by Adobe Photoshop CS5.

Artist Mike Ruiz got a high resolution photograph of Leonardo's art, scanned it in Photoshop, selected the smily girl, and used content-aware fill in Photoshop CS5, a tool that borders in witchcraft—so much that it may make sandwiches for you (almost).
Adobe's tool interpreted the surroundings and generated the complete background in place of the mysterious woman, who apparently was Jesus or his daughter or his third cousin or whatever. One of those. After clicking the OK button, Ruiz sent the result to China, where artists used the image to actually create the oil painting in the same style as da Vinci himself.

Finally, Bacon Cologne!

No longer do you have to dribble bacon down your chin to get a hint of pig on your throat—perfumers Fargginay have invented bacon cologne which has a mix of 11 essential oils in both the Gold (citrus) and Classic (spicy maple) variants, which cost $36 each.

I like Fargginay's little accent over the "o." Really classy.

In Tunisia, act of one fruit vendor unleashes wave of revolution through Arab world








On the evening before Mohammed Bouazizi lit a fire that would burn across the Arab world, the young fruit vendor told his mother that the oranges, dates and apples he had to sell were the best he’d ever seen. “With this fruit,” he said, “I can buy some gifts for you. Tomorrow will be a good day.”

For years, Bouazizi had told his mother stories of corruption at the fruit market, where vendors gathered under a cluster of ficus trees on the main street of this scruffy town, not far from Tunisia’s Mediterranean beaches. Arrogant police officers treated the market as their personal picnic grounds, taking bagfuls of fruit without so much as a nod toward payment. The cops took visible pleasure in subjecting the vendors to one indignity after another — fining them, confiscating their scales, even ordering them to carry their stolen fruit to the cops’ cars.

Before dawn on Friday, Dec. 17, as Bouazizi pulled his cart along the narrow, rutted stone road toward the market, two police officers blocked his path and tried to take his fruit. Bouazizi’s uncle rushed to help his 26-year-old nephew, persuading the officers to let the rugged-looking young man complete his one-mile trek.

The uncle visited the chief of police and asked him for help. The chief called in a policewoman who had stopped Bouazizi, Fedya Hamdi, and told her to let the boy work.

Hamdi, outraged by the appeal to her boss, returned to the market. She took a basket of Bouazizi’s apples and put it in her car. Then she started loading a second basket. This time, according to Alladin Badri, who worked the next cart over, Bouazizi tried to block the officer.

“She pushed Mohammed and hit him with her baton,” Badri said.

Hamdi reached for Bouazizi’s scale, and again he tried to stop her.

Hamdi and two other officers pushed Bouazizi to the ground and grabbed the scale. Then she slapped Bouazizi in the face in front of about 50 witnesses.

Bouazizi wept with shame.

“Why are you doing this to me?” he cried, according to vendors and customers who were there. “I’m a simple person, and I just want to work.”

Revolutions are explosions of frustration and rage that build over time, sometimes over decades. Although their political roots are deep, it is often a single spark that ignites them — an assassination, perhaps, or one selfless act of defiance.

In Tunisia, an unusually cosmopolitan Arab country with a high rate of college attendance, residents watched for 23 years as Zine el-Abidine Ben Ali’s dictatorship became a grating daily insult. From Tunis — the whitewashed, low-rise capital with a tropical, colonial feel — to the endless stretches of olive and date trees in the sparsely populated countryside, the complaints were uniform: It had gotten so you couldn’t get a job without some connection to Ben Ali’s family or party. The secret police kept close tabs on ordinary Tunisians. And the uniformed police took to demanding graft with brazen abandon.

Still, the popular rebellion that started here and spread like a virus to Egypt, Libya and the Persian Gulf states, and now to Yemen and Syria, was anything but preordained. The contagion, carried by ordinary people rather than politicians or armies, hits each country in a different and uncontrollable way, but with common characteristics — Friday demonstrations, Facebook connections, and alliances across religious, class and tribal lines. This wave of change happened because aging dictators grew cocky and distant from the people they once courted, because the new social media that the secret police didn’t quite understand reached a critical mass of people, and because, in a rural town where respect is more valued than money, Mohammed Bouazizi was humiliated in front of his friends.

After the slap, Bouazizi went to city hall and demanded to see an official. No, a clerk replied. Go home. Forget about it.

Bouazizi returned to the market and told his fellow vendors he would let the world know how unfairly they were being treated, how corrupt the system was.

He would set himself ablaze.

“We thought he was just talking,” said Hassan Tili, another vendor.

A short while later, the vendors heard shouts from a couple of blocks away. Without another word to anyone, Bouazizi had positioned himself in front of the municipal building, poured paint thinner over his body and lit himself aflame.

The fire burned and burned. People ran inside and grabbed a fire extinguisher, but it was empty. They called for police, but no one came. Only an hour and a half after Bouazizi lit the match did an ambulance arrive.

Manoubya Bouazizi said her son’s decision “was spontaneous, from the humiliation.” Her clear blue eyes welled as her husband placed at her feet a small clay pot filled with a few white-hot pieces of charcoal, their only defense against a cold, raw, rain-swept day. The Bouazizi family has no money, no car, no electricity, but it was not poverty that made her son sacrifice himself, she said. It was his quest for dignity.

Ben Ali visited Mohammed Bouazizi in the hospital, along with a camera crew. The president made a show of handing Manoubya a check for 10,000 dinars (about $14,000). But the mother said Ben Ali’s staffers took the check back after the cameramen were escorted from the room. “I never got any of it,” she said.

Three weeks after he set himself on fire, Bouazizi died in the burn unit.

In early January, the policewoman was arrested, but it was too late. The story had spread, and three months later, a revolution that sprouted in a small village in Tunisia and flowered in Egypt has morphed into a contagion that threatens regimes in Bahrain and Yemen, has enveloped Libya in civil war, and is unsettling even the region’s more placid monarchies, such as Saudi Arabia and Jordan.

Scientists Grow an Eye in a Petri Dish

A Japanese research team has successfully grown a "rudimentary" mouse eye in a petri dish using stem cells. This has many implications for future research and curing blindness. Below is a time-lapse photo


of the stem sells spontaneously organizing into an "optic cup"—the precursor to an eye. Now they need to grow a little pair of Ray Bans in a petri dish and we'll have the coolest mouse in the world.

Ghostly Lightpainting Uses a Cross-Sectioned Video of an Executed Convict’s Body as Light Source


Lightpainting requires a certain sort of skill to get the sort of marvellous results we've seen previously, but Croix Gagnon and Frank Schott went the whole nine yards and played an animation of a cross-sectioned human body on a laptop, which they then whizzed through the air and took long-exposure photos of.

1,871 slices of a convicted murderer's body who was executed in 1993 and given to science were used to create the animation (which you can see below—and actually use yourself!), Gagnon and Schott employed someone to move it about while they shot photos of it. You can see one of the photos below actually shows the laptop with animation frozen on-screen.

Amazing work, I'm sure you'll agree. If you like the prints enough to spend $700 on one, you can buy them from 12:31, with the proceeds being donated to

"Hand-Screened for Radioactivity" Is Going to Be the New "Grown Locally"



If you're willing to throw down $140 for the tasting menu at Le Bernardin—perhaps the greatest seafood-oriented restaurant in the country, with three Michelin stars and four from the NYT—you can nom on the fluke sashimi without worrying about radioactive contamination.

That's because in addition to no longer sourcing seafood from Japan, chef Eric Ripert's now hand-screening all of the fish coming into the restaurant for radioactive contamination. Will it make patrons feel better while simultaneously subtly inducing more panic? Yes.

Expect this kind of thing to become de rigueur at any place that professes to care about the provenance of its food—well-regarded Sushi Yasuda in NY is already following suit—even as a senior scientist at the FDA tells the NYT, "Is that one fish at the intervention level a public health concern? No, it is not." And another scientist, a professor of marine sciences at SUNY Stony Brook adds that, given the current levels of cesium 137 detected in Japanese fish, you can eat around 35 pounds of it a year and be fine.

But yes, if you're willing to pay for organic beef grown on a particular farm and fed only the finest non-additive grass and massaged daily for all-natural marbling, you can also procure hand-screened, non-radioactive fish. You're paying for it, after all. Me? I like pork better anyway. [NYT]

How Big Weapons Hit Tiny Targets from Incredible Distances

So, let's say our armed forces were in a conflict where they had to enforce a no-fly zone without deploying troops on the ground. How would they do that? Simple: GPS. Oh, and Lasers. And mechanized ordnance that is better at navigating than any meatbag with a map.
In a tense conflict like Libya, where nobody—including the American public—wants US troops stomping around, it might seem like military options are limited. They are: to a gang of super-smart, incredibly accurate missiles and bombs launched from the ocean and sky. In some cases, a missile's solo journey can originate from a submerged submarine hundreds of miles from its target. Which raises the question: Wait, how can it hit a target the size of a shipping container from, like, another country?
It all starts with a plan. Before, say, a $607,000 Tomahawk land attack missile ever leaves the launch tube, it's programmed with a set of instructions—called a pre-mission plan—that tells it where to land. The guide includes the latitude and longitude of the target as well as the coordinates for up to 15 other alternate endings.
Also loaded are stored images of the flight path, which come in handy later.

Getting from point A (say, a sub) to point B (say, a bunker) requires an intricate set of negotiations that the Tomahawk handles on the fly. After our 20-foot-long projectile protagonist pops out of the ocean, it levels low to the water in order to dodge enemy radar. Moving at up to 550mph, the missile is guided by a GPS system similar to the ones 747s use, and a system called Terrain Contour Matching. TERCOM takes note of the immediate landscape, but it's not about sight seeing. The Tomahawk instead compares real time data from its altimeter and radar with satellite imagery from a stored database to make sure it's precisely on course. It's kind of like looking at Google Street View while you walk through a neighborhood. If the missile finds that it has zigged off its route or desired altitude, it aligns itself with the right topography to get back on track.




But things change rapidly in conflict, so the 3,330 Tomahawk Block IV has built-in ability to react to situations like a last-minute change in targeting. In these cases, GPS location data gets updated via a two-way satellite link, and the missile takes an alternate route to another end point. Haven't determined the new target yet? "The missile can go into a loitering mode," explains a super secret Navy official whose name we can't use. "It's not as dramatic as a hover, but it will fly loops in the air, and it will await further tasking."

Remember that stored image of the route to the enemy destination included in the pre-mission plan? Well, if there aren't any changes mid-flight, the missile compares the picture of the route with what's on the ground. "It adjusts based on what it sees," says the Navy official. When everything matches up: Boom. No more shipping container.


Destruction doesn't only come from the sea, either. Other super accurate systems, like certain Guided Bomb Units (GBU) carried on F15E Strike Eagle planes, use lasers and fins for guidance. Before ever leaving the ground, the bombs are programmed to look for a certain laser signature—the same laser signature that the plane is programmed to "paint" on its enemies. See, the bombs are ravenous for these beam-illuminated spots, but their attraction needs to be very, very specific. The Air Force doesn't want Jet #1's bomb hitting Jet #2's target (or, like, a grocery store) by accident.

F15Es have what's called a targeting pod that allows Weapons Systems Officers to look for targets using infrared and electro-optical imaging. You've seen this set up on TV; it's the screen with the crosshairs on it. Once they find the correct spot, the targeting pod computes the coordinates. Then, the jet's computer calculates where the pilot needs to fly and when the bomb needs to drop.

When the range is right, the pilot hits the "pickle button" (for serious—that's what it's called) and the laser guided bomb is dropped from something like 20,000 feet. From here, the on-bomb computer plays a game of find the laser. Bombs are equipped with a glassed-over seeker that kind of looks like an eye. When the seeker locates the laser-illuminated target below, the computer tells the bomb how to move its fins to navigate the free fall. "We can hit anything: buildings, cars, holes in the ground—really there's no limitation," says Major Ryan Ismirle, who flew F15Es in Afghanistan. "I've never seen one—especially in combat-that hasn't hit its target."
