LHC sees hint of high-speed particle pancake








































Particles behaving oddly at the Large Hadron Collider seem to be the strongest signs yet of an unusual "subatomic pancake" called a colour-glass condensate. Theory suggests that matter takes on this guise when it is travelling near the speed of light – relativistic speeds – but the effect has not yet been officially observed.












The particles in atomic nuclei are made up of quarks held together by gluons. Gluons are elementary particles responsible for the strong force, also known as the colour force, which is the fundamental force that holds subatomic particles together.













Theory says that at relativistic speeds, particles become flattened and gain additional gluons, creating what is called a colour-glass condensate. Discovering whether relativistic matter actually behaves this way will help physicists better understand the strong force.












The hints of a colour-glass condensate come from CMS, one of the main detectors in the LHC at CERN, near Geneva, Switzerland. Researchers there smashed together beams of protons with beams of lead ions, producing showers of subatomic particles that flew away in all directions at high speed.











The latest smash-up was only meant to be a trial run in preparation for further collisions in January. But analysis of the data revealed something odd: the paths of certain pairs of particles flung out after the collisions seemed to be linked in unexpected ways.












Added ingredients













For example, two particles produced by the same collision may be heading in opposite directions, but they may also be curving slightly upwards in synch. This coordinated motion is odd, since the particles should fly away randomly.












"Most common models assume these particles would be uncorrelated," says Gunther Roland, a physicist at the Massachusetts Institute of Technology and a CMS team member. The data, however, say otherwise. "Such correlations are not so easy to create," says Roland.











Similar effects have previously been seen from high-speed collisions of heavy ions, which can create what is known as a quark-gluon plasma. This is the soupy mix of basic particles thought to have existed millionths of a second after the big bang.













Ripples in the plasma can affect particle pairs emitted from collisions by nudging them in the same direction as each other, producing a distinctive swerve that looks similar to the patterns in the CMS data. But collisions between protons and lead ions should not produce enough of the particles to create quark-gluon plasma, meaning there might be an alternative explanation.











In a colour-glass condensate, the extra gluons in the flattened particles would exist as both particles and waves. Their wave functions might become linked in ways that can influence the directions of the particle pairs, akin to the linked behaviours in quantum entanglement.












Collecting clues













"It is a possible explanation, but it really hasn't been confirmed," says Roland. The CMS test experiment ran for just 4 hours. The full-scale runs early next year should provide 10,000 to 100,000 times more data. "I'm very excited to see what we're going to learn about this in January," he says.












The initial results are very interesting, says David Evans of the University of Birmingham, UK, and a member of the team working with ALICE, another LHC detector. But Evans agrees there is not enough evidence to point the finger at colour-glass condensate just yet.












ALICE's results on proton-lead collisions so far do not indicate they are producing quark-gluon plasma, Evans adds, and his team is currently analysing data that will show whether ALICE has also detected hints of a colour-glass condensate.

Golf: Supakorn soars ahead in King's Cup






BANGKOK: Thailand's Supakorn Utaipat continued his dream run at the $500,000 King's Cup when he signed for a five-under-par 67 to take the second round lead on Friday.

The 22-year-old compiled a two-day total of 13-under-par 131 to take a two-shot advantage over the chasing pack heading into the weekend rounds.

Singapore's Mardan Mamat carded a 70 to take a share of second place alongside England's Chris Rodgers and defending champion Udorn Duangdecha of Thailand at the Singha Park Khon Kaen Golf Club in northeast Thailand.

Taiwan's Chiang Chen-chih made one of the biggest moves with an impressive 64 to take a share of fifth place with compatriot Lin Wen-tang, Australian Wade Ormsby, the Philippines' Elmer Salvador as well as Thais Boonchu Ruangkit and Prom Meesawat at the King's Cup, which is the third last event on the 2012 Asian Tour schedule.

Supakorn was delighted with his lead but admitted feeling the pressure ahead of the weekend rounds.

"This is only my second start on the Asian Tour and honestly I'm feeling nervous as I've never been in this position before," said Supakorn, who turned professional this year.

After enjoying one of his best starts on the Asian Tour with an opening 63, Mardan continued his charge towards his fourth Tour title even though he could not match his first round heroics.

The cut was set at three-under with a total of 70 players making it into the weekend rounds.

The King's Cup is making its return after a year's absence following the floods in Thailand last year.

Leading scores after the second round (par 72):

131 - Supakorn Utaipat (THA) 64-67

133 - Chris Rodgers (ENG) 64-69, Mardan Mamat (SIN) 63-70, Udorn Duangdecha (THA) 65-68

134 - Chiang Chen-chih (TPE) 70-64, Elmer Salvador (PHI) 68-66, Prom Meesawat (THA) 65-69, Boonchu Ruangkit (THA) 67-67, Lin Wen-tang (TPE) 66-68, Wade Ormsby (AUS) 71-63

Apple released an update yesterday to let
Mac software handle raw photos from eight new cameras, most of them high-end compact models.


The Digital Camera Raw Compatibility Update 4.02 lets Aperture 3, iPhoto 11, and other software handle raw photos from the following cameras:


• Nikon Coolpix P7700


• Olympus Pen E-PL5


• Olympus Pen E-PM2


• Olympus Stylus XZ-2


• Panasonic Lumix DMC-GH3


• Sony Alpha NEX-5R


• Sony Alpha NEX-6


• Sony Alpha SLT-A99


Raw photos offer more flexibility and higher image quality than conventional JPEGs, but photographers must use software to process the photos, and companies must write software to decode new cameras' proprietary formats.




A slew of new raw photo formats is arriving as camera makers struggle for dominance in the new market compact "mirrorless" cameras with interchangeable lenses. Most of the new cameras Apple now supports are of this mirrorless ilk.


For an entertaining look at how the mirrorless market is developing, I heartily recommend this mirrorless camera party video from Camera Store in Calgary, Canada.

Pictures: Inside the World's Most Powerful Laser

Photograph courtesy Damien Jemison, LLNL

Looking like a portal to a science fiction movie, preamplifiers line a corridor at the U.S. Lawrence Livermore National Laboratory's National Ignition Facility (NIF).

Preamplifiers work by increasing the energy of laser beams—up to ten billion times—before these beams reach the facility's target chamber.

The project's lasers are tackling "one of physics' grand challenges"—igniting hydrogen fusion fuel in the laboratory, according to the NIF website. Nuclear fusion—the merging of the nuclei of two atoms of, say, hydrogen—can result in a tremendous amount of excess energy. Nuclear fission, by contrast, involves the splitting of atoms.

This July, California-based NIF made history by combining 192 laser beams into a record-breaking laser shot that packed over 500 trillion watts of peak power-a thousand times more power than the entire United States uses at any given instant.

"This was a quantum leap for laser technology around the world," NIF director Ed Moses said in September. But some critics of the $5 billion project wonder why the laser has yet to ignite a fusion chain reaction after three-and-a-half years in operation. Supporters counter that such groundbreaking science simply can't be rushed.

Man Arrested in Fla. Girl's 1993 Disappearance













Police have arrested a 42-year-old man and charged him with murder in the case of a Florida girl who vanished almost 20 years ago.


Andrea Gail Parsons, 10, of Port Salerno, Fla., was last seen on July 11, 1993, shortly after 6 p.m. She had just purchased candy and soda at a grocery store when she waved to a local couple as they drove by on an area street and honked, police said.


Today, Martin County Sheriff's Department officials arrested Chester Duane Price, 42, who recently lived in Haleyville, Ala., and charged him with first-degree murder and kidnapping of a child under the age of 13, after he was indicted by a grand jury.


Price was acquainted with Andrea at the time of her disappearance, and also knew another man police once eyed as a potential suspect, officials told ABC News affiliate WPBF in West Palm Beach, Fla.

"The investigation has concluded that Price abducted and killed Andrea Gail Parsons," read a sheriff's department news release. "Tragically, at this time, her body has not been recovered."


The sheriff's department declined to specify what evidence led to Price's arrest for the crime after 19 years or to provide details to ABCNews.com beyond the prepared news release.


Reached by phone, a sheriff's department spokeswoman said she did not know whether Price was yet represented by a lawyer.


Price was being held at the Martin County Jail without bond and was scheduled to make his first court appearance via video link at 10:30 a.m. Friday.


In its news release, the sheriff's department cited Price's "extensive criminal history with arrests dating back to 1991" that included arrests for cocaine possession, assault, sale of controlled substance, aggravated assault with a deadly weapon and violation of domestic violence injunction.


"The resolve to find Andrea and get answers surrounding the circumstances of her disappearance has never wavered as detectives and others assigned have dedicated their careers to piecing this puzzle together," Martin County Sheriff Robert L. Crowder said in a prepared statement. "In 2011, I assigned a team of detectives, several 'fresh sets of eyes,' to begin another review of the high-volume of evidence that had been previously collected in this case."


A flyer dating from the time of Andrea's disappearance, and redistributed by the sheriff's office after the arrest, described her as 4-foot-11 with hazel eyes and brown hair. She was last seen wearing blue jean shorts, a dark shirt and clear plastic sandals, according to the flyer.


The sheriff's department became involved in the case after Andrea's mother, Linda Parsons, returned home from work around 10 p.m. on July 11, 1993, to find her daughter missing and called police, according to the initial sheriff's report.

The moon is still waiting for visitors



































"WE'VE been there before." It was with those words that President Barack Obama, speaking in 2010, ruled out a return to the moon. Whether deliberately or not, his words echoed George Mallory's famous 1923 justification for climbing Mount Everest: "Because it's there".











Now it seems that NASA might return to the moon after all. Following weeks of speculation, a scientist at the European Space Agency, which is partnering with NASA, has told New Scientist that ESA anticipates two new lunar missions (see "Humans head for moon's orbit - and beyond"). The second of these would see humans orbit the moon, but not attempt to land on its surface.













That, it seems, will be left to private firms. Why would they bother? Perhaps to extract resources. Perhaps for the publicity. And perhaps because it's still there.

Curiosity: Behind the amazing success (and disaster) of a mobile gaming hit




Curiosity lets people tap little "cubelets" to make them disappear. Writing messages is one motivation to keep on tapping at the 64 billion cubelets.

For storied video game designer Peter Molyneux, November 6 was supposed to be the calm before the storm. But it became the storm itself when his newest project, Curiosity, arrived a day early and exploded in popularity.


Molyneux's new gaming startup, 22Cans, planned to launch Curiosity on November 7. Twenty-two hours ahead of time, though, Apple's App Store published the "experiment," which is something like letting thousands of people pop the same sheet of bubble wrap at the same time.


So began a roller-coaster ride that combined a humiliating server failure with an intriguing new take on global-scale video games in the smartphone era. But now, with the server problems licked, Curiosity 2.0 due soon, and 22Cans' grander plans taking shape, Molyneux is starting to sound less mortified and more optimistic.


"It's literally the biggest tragedy I've ever had in my career," Molyneux said in an interview. "It's also been the biggest joy."




That's a big change from two weeks ago, when word of Curiosity got out and the game went viral. 22Cans' servers were overwhelmed, preventing many from reaching the game's giant virtual online cube and wiping out players' stores of carefully collected virtual coins.


But instead of dealing with the crisis at 22Cans headquarters in Guildford, England, Molyneux was trying to get back from a conference in Israel. He spent four and a half agonizing hours trying to get through Tel Aviv's notoriously rigorous airport security more than 2,000 miles away. (For a blow-by-blow look at the drama, check the timeline of Curiosity's difficult debut.)


"Israel has got the most insane security, and through none of it are you allowed to use your mobile phone," Molyneux said. "Knowing Curiosity was alive, I was occasionally pretending to drop something to look at my phone."


The desperation of the moment still was evident in his voice as he described how his hopes of communicating were dashed once again on the plane.


"As luck would have it, the person sitting next to me on the plane was an aircraft inspector. He said, 'You can't use that,'" Molyneux recounted. When the inspector left his seat for a moment, Molyneux mashed his phone against the window to try to get a signal. He said was thinking, "I don't care if the plane crashes and kills a thousand people. I've got to find out what's happening."


Curiosity was simply too popular too soon, almost immediately overtaking 22Cans' plan to gradually increase server capacity.


"I'll be honest. This is my fault. I never in my wildest dreams expected millions of people to download Curiosity in the first few days. It's an experiment. You just tap on it. I could see in my mind's eye, even with my most optimistic nature, we'd see at first a thousand people, maybe after a month, a hundred thousand," Molyneux said. "That hundred thousand figure was reached within three hours of launching Curiosity."

To cope with the load, 22cans' Curiosity team of six programmers stripped out lots of features -- the Facebook log-in, the ability to check where on the cube your contacts were tapping, detailed statistics. With the upcoming release of Curiosity 2.0, the company will restore these features and hopes to fulfill its original ambition. It will make Curiosity a real-time collective experience rather than individual actions that only synchronize with others' actions in fits and starts. And it will open the door to more experiments.


Video game renown
Perhaps Molyneux' track record has something to do with it. He's a notable figure in the video game world -- notable enough for membership in the Order of the British Empire for distinguished service.


In the 1980s, "I was selling floppy disks to schools," Molyneux said, but he found they sold better with free games on them. He then moved into writing those games himself, though his first, Entrepreneur, was an abject failure that sold only two copies. His fortunes turned later that decade when his "god game" Populous sold 5 million copies, luring players who wanted to lead a civilization in competition with another deity.

After that came hits such as Dungeon Keeper, a role reversal in which the player defends his territory against incursion from heroes, and Project Milo, in which a player uses a Kinect controller to interact with a boy and guide him around a virtual world.


Central to many video games is the idea of motivation. Players stay engaged with opportunities to solve puzzles, vanquish enemies, build empires, and escape into alternative realms where they have more control over the future.


Molyneux has experimented with morality as a motivation, too. Where some games such as the Grand Theft Auto series explore the rewards of criminality, Molyneux's Fable series from Microsoft offers moral choices in which choosing the "good" path can help the player's fortunes.


Curiosity accommodates some very different motives: The urge to reveal hidden photos and text. The desire to tidy up. The instinct to collaborate on a group project the same way thousands of ants build an anthill one grain of sand at a time. The compulsion to write crude graffiti -- or to obliterate it. And, closest to Molyneux's heart, the desire to find out the secret message he's hidden deep within the cube.


What is Curiosity?
Curiosity is many things. It's the first of 22 experiments that 22Cans plans to launch on the road to building new games adapted for the era of the Net-connected mobile device. It's a marketing vehicle to promote 22Cans' Kickstarter-funded god game, Godus. And at its most basic level, it's a game whose bare-bones simplicity actually has room for surprising complexity.

Curiosity, an app for iOS and
Android, is as primitive and repetitive as popping plastic bubble-wrap. But apparently it's just as addictive, because it's kept hundreds of thousands of people engaged.


The game shows a single cube floating in a virtual room. This cube is constructed from more than 64 billion tiny cubelets that become visible if zoom in close. If you tap a cubelet, it disappears with a tinkling noise into tiny shards.


So what makes this better than virtual bubble wrap?


First of all, there are the gold coins. Destroying a cubelet gets you a single coin at first, but multipliers kick in as you tap ever more cubelets without missing and tapping a blank patch. You get double the coins after a run of 12 cubelets, triple at 26, quadruple at 42, and so on.


It's a pretty crude reward system, but you can cash in your coins for assorted tools that let you destroy more cubes per tap. Some tools are disabled for now, to be unlocked in the future, so perhaps there's a reason to save up.


Molyneux is intrigued by the possibilities. For example, what will happen when the end gets close?


"If you watch a marathon, all the runners will run in a pack, slipstreaming behind each other. Then there will come a point where somebody makes a break for it and runs in front," and he expects a similar realization in Curiosity when people realize it's changing from a cooperative project to a competition.


"That's why we have this notion of saving up," he adds. "Are you a hoarder? Will you spend [your coins] in a blaze of glory on the last few levels? Or are you a cooperator, spending now to get through early levels? It's a deeply interesting experiment in group mentality."


More experiments will center on Curiosity's virtual money -- but later with a connection to real-world money through in-app purchases.


"It's going to form a part of the experiment at some point in the cube. Monetization needs to be fair. We need to get our servers reliable before we monetize in any way," he said. "To test that motivation is fascinating."


Art and graffiti
And other motives are at work, too. Some people like to rapidly tap with multiple fingers, leaving tracks of obliterated cubes behind with a strategy that's good for long runs of coins. Others like to tidy up, perhaps motivated by the bonus awarded if a player clears the screen of all cubelets.




Artwork such as this heart often doesn't last long as others tap away the cubelets.

Second, there's the chance for global graffiti. Many people use the face of the cube as a tabula rasa, tapping away cubelets to construct pixelated words, patterns, or artwork. At the same time, others undo what's been created.


"One person is turning everything risque into little works of art. A lot of kids draw penises. He goes round and changes them into dog's faces and palm trees," Molyneux said.


Someone even painstakingly tapped out a marriage proposal, Molyneux said. "A lot of people want to express themselves on the cube," once they realize they're "connected to the entire world."


Third, there are the pictures. Some layers have photographs or other imagery that people want to reveal. Underneath one of the early layers were close-up photos of eyes, and people tapped away the cubes to reveal those eyes first before turning to the more mundane regions around them.


Molyneux was intrigued to see that on one layer, showing words excerpted from Charles Dickens, people tapped away enough to understand the word, but moved on to the next before instead of tapping to fully reveal the world.


The secret
Last, there's the secret.


Somewhere inside the cube is one cubelet that, when tapped, will reveal to a single person a Web address with a message that only Molyneux and one other person know. And Molyneux is terribly excited about it.


"I wake up thinking about it," he said. "I am known for saying exciting things and getting people excited, maybe overexcited, and that's been interpreted as overpromising. Maybe this time I'm understating the promise."


The secret isn't necessarily in the last, centermost cubelet, Molyneux said. If it looks like people are losing interest, 22Cans will "bring forward the end date," but right now he expects that "we have many hundreds of layers to go through yet."


The impetus for Curiosity was a TED talk by J.J. Abrams about the power of a secret, Molyneux said.


"When he was a kid, his grandfather gave him a locked box. He said, 'Don't open the box, just wonder what's in the box. It motivated him to be a brilliant writer," Molyneux said. "If that motivated him, maybe it's enough for me to say, 'Inside the center of this cube, for one person, there is something amazing, wonderful, and life-changing. It isn't just a dead cat or philosophical saying or video of 22cans saying 'Hurrah!" It is something truly meaningful."


And that curiosity apparently motivates people. 22Cans can show messages across the cube, and one is the phrase, "What's inside the cube?"


"What happens to the tap rate if we remind people? We notice the length of time people tap goes up," Molyneux said. Not only that, it keeps them coming back to the cube even though most people abandon new apps quickly. "That keeps them coming back."


Promoting Godus
Molyneux knows what to do with the limelight. He's promoting Curiosity, of course, and a succeeding experiment that will be "more like a game than Curiosity." And last week, peeling away one Curiosity cube layer revealed another 22Cans ambition: a new god game called Godus. The company is funding Godus with Kickstarter, and it's raised $270,000 since then.

It's a new god game that draws on Populous, Dungeon Master, Black and White, and Fable. "We're going to steal the best bits and throw away the worst bits," he said in a video about Godus. That means the mutable landscape of Populous, the subterranean treasures of Dungeon Keeper, and the direct intervention of the hand of god in Black and White, he said. It'll run on Windows PCs, iOS devices, and maybe Macs, and it'll work in adrenaline-charged multiplayer or more relaxed single player modes.


But don't expect Godus to be a direct descendent of Curiosity's massive multiplayer approach, since linking each player's worlds into a single universe will be technically difficult and expensive. "Having all these worlds connected is a huge thing and it's going to require lots of servers, so big stretch goal, I'm afraid," Molyneux said in a video about Godus.


It's clear, though, that Molyneux is hooked on the idea of a game that spans the world through smartphones. "It's a new psychology. Never before have we been able to join people together in a single experience," Molyneux said.


He revels in what it's shown so far.


"On Curiosity, people have proposed to each other. There are obituaries on the cube. There are people from all cultures. There are political statements on the cube, art on the cube, crudity on the cube, censorship on the cube. All these come about because of stupidly simple thing of people tapping. If I can learn from that, then I could be part of making an experience that 100 million people could touch in one day," Molyneux said.


"We'd better get the servers right."

Caterpillar Fungus Has Anti-Inflammatory Properties


In the Tibetan mountains, a fungus attaches itself to a moth larva burrowed in the soil. It infects and slowly consumes its host from within, taking over its brain and making the young caterpillar move to a position from which the fungus can grow and spore again.

Sounds like something out of science fiction, right? But for ailing Chinese consumers and nomadic Tibetan harvesters, the parasite called cordyceps means hope—and big money. Chinese markets sell the "golden worm," or "Tibetan mushroom"—thought to cure ailments from cancer to asthma to erectile dysfunction—for up to $50,000 (U.S.) per pound. Patients, following traditional medicinal practices, brew the fungal-infected caterpillar in tea or chew it raw.

Now the folk medicine is getting scientific backing. A new study published in the journal RNA finds that cordycepin, a chemical derived from the caterpillar fungus, has anti-inflammatory properties.

"Inflammation is normally a beneficial response to a wound or infection, but in diseases like asthma it happens too fast and to too high of an extent," said study co-author Cornelia H. de Moor of the University of Nottingham. "When cordycepin is present, it inhibits that response strongly."

And it does so in a way not previously seen: at the mRNA stage, where it inhibits polyadenylation. That means it stops swelling at the genetic cellular level—a novel anti-inflammatory approach that could lead to new drugs for cancer, asthma, diabetes, rheumatoid arthritis, and cardiovascular-disease patients who don't respond well to current medications.

From Worm to Pill

But such new drugs may be a long way off. The science of parasitic fungi is still in its early stages, and no medicine currently available utilizes cordycepin as an anti-inflammatory. The only way a patient could gain its benefits would by consuming wild-harvested mushrooms.

De Moor cautions against this practice. "I can't recommend taking wild-harvested medications," she says. "Each sample could have a completely different dose, and there are mushrooms where [taking] a single bite will kill you."

Today 96 percent of the world's caterpillar-fungus harvest comes from the high Tibetan Plateau and the Himalayan range. Fungi from this region are of the subspecies Ophiocordyceps sinensis, locally known as yartsa gunbu ("summer grass, winter worm"). While highly valued in Chinese traditional medicine, these fungi have relatively low levels of cordycepin. What's more, they grow only at elevations of 10,000 to 16,500 feet and cannot be farmed. All of which makes yartsa gunbu costly for Chinese consumers: A single fungal-infected caterpillar can fetch $30.

Brave New Worm

Luckily for researchers, and for potential consumers, another rare species of caterpillar fungus, Cordyceps militaris, is capable of being farmed—and even cultivated to yield much higher levels of cordycepin.

De Moor says that's not likely to discourage Tibetan harvesters, many of whom make a year's salary in just weeks by finding and selling yartsa gunbu. Scientific proof of cordycepin's efficacy will only increase demand for the fungus, which could prove dangerous. "With cultivation we have a level of quality control that's missing in the wild," says de Moor.

"There is definitely some truth somewhere in certain herbal medicinal traditions, if you look hard enough," says de Moor. "But ancient healers probably wouldn't notice a 10 percent mortality rate resulting from herbal remedies. In the scientific world, that's completely unacceptable." If you want to be safe, she adds, "wait for the medicine."

Ancient Chinese medical traditions—which also use ground tiger bones as a cure for insomnia, elephant ivory for religious icons, and rhinoceros horns to dispel fevers—are controversial but popular. Such remedies remain in demand regardless of scientific advancement—and endangered animals continue to be killed in order to meet that demand. While pills using cordycepin from farmed fungus might someday replace yartsa gunbu harvesting, tigers, elephants, and rhinos are disappearing much quicker than worms.

Two Winners in Record Powerball Jackpot













Winning tickets for the record Powerball jackpot worth more than $587 million were purchased in Arizona and Missouri.


Missouri Lottery official Susan Goedde confirmed to ABC News this morning that one of the winning tickets was purchased in the state, but they would not announce which town until later this morning.


Arizona lottery officials said they had no information on that state's winner or winners but would announce where it was sold during a news conference later in the day.


The winning numbers for the jackpot were 5, 23, 16, 22 and 29. The Powerball was 6.


The jackpot swelled to $587.5 million, according to Lottery official Sue Dooley. The two winners will split the jackpot each getting $293.75 million. The cash payout is $192.5 million each.


An additional 8,924,123 players won smaller prizes, according to Powerball's website.


"There were 58 winners of $1 million and there were eight winners of $2 million. So a total of $74 million," said Chuck Strutt, Director of the Multi-State Lottery Association.


In Photos: Biggest Lotto Jackpot Winners


This is the 27th win for Missouri, ranking it second in the nation for lottery winners after Indiana, which has 38 wins. Arizona has had 10 Powerball jackpot wins in its history.


Players bought tickets at the rate of 131,000 every minute up until an hour before the deadline of 11 p.m. ET, according to lottery officials.


The jackpot had already rolled over 16 consecutive times without a winner. That fact, plus the doubling in price of a Powerball ticket, accounted for the unprecedented richness of the pot.






"Back in January, we moved Powerball from being a $1 game to $2," said Mary Neubauer, a spokeswoman at the game's headquarters in Iowa. "We thought at the time that this would mean bigger and faster-growing jackpots."


That proved true. The total, she said, began taking "huge jumps -- another $100 million since Saturday." It then jumped another $50 million.


The biggest Powerball pot on record until now -- $365 million -- was won in 2006 by eight Lincoln, Neb., co-workers.
As the latest pot swelled, lottery officials said they began getting phone calls from all around the world.


"When it gets this big," said Neubauer, "we get inquiries from Canada and Europe from people wanting to know if they can buy a ticket. They ask if they can FedEx us the money."


The answer she has to give them, she said, is: "Sorry, no. You have to buy a ticket in a member state from a licensed retail location."


About 80 percent of players don't choose their own Powerball number, opting instead for a computer-generated one.
Asked if there's anything a player can do to improve his or her odds of winning, Neubauer said there isn't -- apart from buying a ticket, of course.


Lottery officials put the odds of winning this Powerball pot at one in 175 million, meaning you'd have been 25 times more likely to win an Academy Award.


Skip Garibaldi, a professor of mathematics at Emory University in Atlanta, provided additional perspective: You are three times more likely to die from a falling coconut, he said; seven times more likely to die from fireworks, "and way more likely to die from flesh-eating bacteria" (115 fatalities a year) than you are to win the Powerball lottery.


Segueing, then, from death to life, Garibaldi noted that even the best physicians, equipped with the most up-to-date equipment, can't predict the timing of a child's birth with much accuracy.


"But let's suppose," he said, "that your doctor managed to predict the day, the hour, the minute and the second your baby would be born."


The doctor's uncanny prediction would be "at least 100 times" more likely than your winning.


Even though he knows the odds all too well, Garibaldi said he usually plays the lottery.


When it gets this big, I'll buy a couple of tickets," he said. "It's kind of exciting. You get this feeling of anticipation. You get to think about the fantasy."


So, did he buy two tickets this time?


"I couldn't," he told ABC News. "I'm in California" -- one of eight states that doesn't offer Powerball.


In case you were wondering, this Saturday's Powerball jackpot is starting at $40 million.
