"Argo", "Lincoln" vie for Oscars crown in open race






LOS ANGELES - Steven Spielberg goes into next weekend's Oscars with the most nominations for his presidential "Lincoln" but the momentum is all with Ben Affleck's thriller "Argo" in the Academy Awards home straight.

And while the Hollywood veteran and the young pretender vie for the Oscars best picture crown, several other frontrunners remain hard on their heels, in one of the least predictable Oscar races in recent memory.

Taiwan-born Lee Ang's 3D spectacular "Life of Pi," Osama bin Laden manhunt movie "Zero Dark Thirty" and romcom "Silver Linings Playbook" could all be in with a chance at the Oscars, the climax of Tinseltown's annual awards season.

Spielberg and Lee are frontrunners for best director, while "Lincoln" star Daniel Day-Lewis is widely seen as a shoo-in for best actor. For best actress the hot money is on Jessica Chastain for her part in "Zero Dark Thirty" or "Hunger Games" star Jennifer Lawrence.

But Affleck's Iran hostage drama, despite only winning seven nominations -- against 12 for "Lincoln," 11 for "Life of Pi" and eight each for "Silver Linings Playbook" and "Les Miserables" -- has a clear edge for best picture.

It has swept up top prizes at a string of key awards shows, including the Golden Globes, the Screen Actors Guild (SAG), Producers Guild of America (PGA), the Directors Guild of America (DGA), and Britain's BAFTA last weekend.

Affleck has gotten used to making acceptance speeches over the last two months -- but he has been tightlipped on his prospects for the all-important 85th Academy Awards, to be held at Hollywood's Dolby Theatre next Sunday.

"I just feel so incredibly honoured to be nominated as a producer for this movie. To be here at the big party," he said at the Oscar Nominees Luncheon, the annual gathering of those in the race, held in Beverly Hills on February 4.

Indeed, his best picture nomination is as a co-producer of the film -- along with George Clooney and Grant Heslov -- rather than as a director, a category in which he was not nominated, in a perceived snub.

Snub or no snub, he will be among presenters at the show, along with a Who's Who of A-listers including Halle Berry, Sandra Bullock, Nicole Kidman, Reese Witherspoon, Robert Downey Jr, Samuel L Jackson, and Meryl Streep.

"Family Guy" creator Seth MacFarlane will be hosting, a move organizers hope will attract younger viewers among the hundreds of millions watching live around the world.

Other nominees presenting include Chastain -- best actress frontrunner for playing a relentless CIA agent on the hunt for Osama, in Oscar-winning director Kathryn Bigelow's controversial "Zero Dark Thirty".

But Lawrence, star of the "Hunger Games" blockbuster franchise, could also win the category for her portrayal of mixed-up Tiffany to Bradley Cooper's bipolar ex-teacher in "Silver Linings Playbook".

Cooper is up for best actor, along with Hugh Jackman for "Les Miserables", Joaquin Phoenix for "The Master" and Denzel Washington for "Flight" -- but Day-Lewis is widely forecast for a record third Oscar for his "Lincoln" turn.

For best director, 66-year-old Spielberg will be hoping for his first Oscar since "Saving Private Ryan" in 1999.

But he is up against Lee -- whose "Brokeback Mountain" won best picture in 2006 -- as well as Michael Haneke for his Cannes-winning "Amour", David O Russell for "Silver Linings Playbook" and Benh Zeitlin for "Beasts of the Southern Wild".

Best supporting actor nominees are Alan Arkin for "Argo", Robert De Niro for "Silver Linings Playbook", Philip Seymour Hoffman for "The Master", Tommy Lee Jones for "Lincoln" and Christoph Waltz for "Django Unchained".

For supporting actress Anne Hathaway is tipped to win for performance in "Les Miserables" -- including her heart-wrenching close-up rendition of "I Dreamed a Dream" -- against Amy Adams for "The Master", Sally Field in "Lincoln", Helen Hunt in "The Sessions" and Jacki Weaver in "Silver Linings Playbook".

The Oscars have a musical theme this year, including a performance by Britain's Adele singing the Oscar-nominated 007 theme tune "Skyfall" as well as by Shirley Bassey and Norah Jones, and Barbra Streisand, in her first Oscars turn since 1977.

STORY HIGHLIGHTS


  • Yes, there ARE some rules to the Internet, though, for now they're mainly an inside joke

  • Some rules based on pop culture, some have become Web memes

  • Other rules ominously quote Anonymous

  • Is there a need for rules on the vast and wild Web? Depends on where you stand




Editor's note: In the gallery above, we've selected a handful of our favorite Internet rules, or truths. (You might recognize a few.) What are some of yours? Tell us in the comments. We'll feature some of the best on CNN.


(CNN) -- Hello!


Welcome to the Internet. It's a big place, so let me show you around.


You're approaching Oversharing Pass, where residents routinely post too much information. The Facebook Gorge and Twitter Triangle are particularly nefarious time-sucks. Restraint is advised.


Up ahead is Hyperbole Junction, which is the Worst. Spot. Ever. We recommend that you maintain an even keel and stay to the center; the extreme left and right can be dangerous.


And over there is the infamous Lair of Sociopaths, the home of trolls and loners who mercilessly mock everyone who enters their territory. Watch your step: They may trip you up and you'll fall into the Chasm of Lulz.


Our world isn't all dangerous, of course. You may visit Squee City, where images of cute cats and laughing babies fill the landscape. You'll also meet countless kind strangers, hilarious raconteurs and hard-working fact-checkers. They make it all worthwhile.


Hmm. Maybe it would be easier if you had a guide -- you know, some rules to help you find your way.


What, you didn't know there are rules of the Internet?


Of course there are rules. How do you think we maintain order around here?


A parody of rules


That's a joke.


But there really are some rules of the Internet -- even if they, too, began as kind of a joke.


According to the site KnowYourMeme.com, the Rules began around 2006 as a guide for the Internet collective Anonymous and emerged on the old Encyclopedia Dramatica, a bawdy meme catalog. Soon a version emerged on 4chan, an online bulletin board where most users post anonymously, says Jamie Cohen, director of web/digital media at Hofstra University's School of Communication.


"Chris Poole (4chan's founder) kind of designed it, kind of like a Netiquette rules," he says, describing the unspoken code of conduct that lubricates Internet discourse. (Poole has attributed the rules to Gaia Online, a role-playing community.)


But the rules of the Internet deliberately mocked many of those conventions. The self-reflexive parody fit perfectly with its community's attitude, points out Anthony Rotolo, a professor at Syracuse University's School of Information Studies.


"These jokes are meant to comment on something happening in the world," he says. "Later they get accepted as truisms or become a meme."


The absurdity has been reflected even in the supposed number of rules. Though the best-known first version claimed there were 50 rules, only 18 were listed. Number 1 was initially "Do not talk about Rules 2-33"; no Rules 2-33 were on the list.


The sarcastic attitude was reinforced by the kicker found on Encyclopedia Dramatica. It was a parody of Wikipedia's stub language: "This article is crap. You can help by completely re-writing it."


'Fight Club' and Monty Python


Very quickly, the lists started multiplying and expanding, liberally borrowing from comedy, Web culture and math-science tropes. On one list, a few were designated by complex numbers and mathematical symbols. Some were observations; others were directives.




Some have traced the Internet rules to Chris Poole, the founder of 4chan.



Two rules were taken from "Fight Club": "You do not talk about 4chan (or "/b/," 4chan's random, free-wheeling bulletin board) and "You DO NOT talk about 4chan." One version of Rule 6 stated "There is no Rule 6," which is from a Monty Python sketch. Rule 42, "Always bring a towel," was drawn from Douglas Adams' "The Hitchhiker's Guide to the Galaxy" series. (If you have to ask, read the books.) "Profit," Rule 49, came from "South Park."


Other rules went the reverse direction and became part of mainstream culture. Rule 34 -- "If it exists, there is porn of it" -- is likely the most famous. But there's also "Pics or it didn't happen" (Rule 30), "For every given male character, there is a female version of that character; conversely for every given female character, there is a male version of that character" (Rule 63) and, of course, the corollary to Rule 34 -- "If no porn of it exists at the moment, it will be made" (Rule 35).


Most retained a sense of humor, riffing off established rules and occasionally ending with a giggly "No exceptions."


But a handful were, and remain, as serious as a judge -- notably the three directly about Anonymous (commonly Rules 3-5):


- We are Anonymous.


- We are legion.


- We do not forgive, we do not forget.


The overall Internet rules may have started as a joke, but such ominous language from Anonymous speaks to some of the paradoxes of the Web:


Rules? Why do we need some stinkin' rules?


After all, rules can be helpful -- or divisive. They can create community -- or subvert it.


Even Anonymous, the activist group itself, cuts both ways, says Rotolo. When it hacked the extremist Westboro Baptist Church, many people cheered. But when it goes after less unpopular targets, some cry vigilantism.


Cohen says that the rules themselves try to have it both ways. They're funny until someone gets hurt.


They "play more of a game type of role. They can be bent or broken or cheated or moved around, as you would in any game that has no physical reaction," he says. "That doesn't take into account ever the result of real people being affected by this -- such as teenagers, children, anybody who's seeing things that they shouldn't."


He adds, "There's a lot of rules in there that work for (the creators) more than anyone else. Until they become victims of their own thing, they don't know how powerful the rules are."


Evolving from the Wild West


Of course, the Internet isn't that old, and we're still in its Wild West era in many ways. As the technology evolves from a handful of hackers on Usenet bulletin boards to billions of users on officially sponsored sites, the customs -- the rules -- of the Web will evolve with it.


But we're not talking about the kinds of changes that your family makes to the rules of Monopoly (no, Free Parking is NOT for the pool of money acquired via Chance and Community Chest). We're talking something more expansive: All the established customs of our carbon-based life forms, making way for the instantaneous and virtual modes of silicon-based electronics.


Who knows what new rules may be written?


"When you're in the midst of social change, it's impossible to determine where it's going," says Peter S. Vogel, a former programmer who's now a Dallas-based attorney. "And I think we are in the greatest social change in the history of humans, because there are no boundaries of geography or time."


We haven't even sorted out what happens when the differences in local culture meet global technology. Bruce Umbaugh, a philosophy professor at Webster University in St. Louis who teaches a course on philosophy and technology, argues that not all parts of the world are as tolerant or open-minded as Western democracies.



There's a lot of rules in there that work for (the creators) more than anyone else.
Jamie Cohen, Hofstra University



"There are a lot of other places in the world that are actively using the technology of the Internet to control the free communication among citizens, and to identify critics of the government and hurt them," he says. "We need to be mindful in what we advocate from our perspective that the tools that are implemented on the Net are tools for the global Net."


In other words, citizens of other countries already face actual, enforceable rules -- unlike the folkways established by Web users in the West. Witness the frictions of the Arab Spring, or the restrictions of societies such as North Korea.


It's the kind of perspective that provides a different context for the issues raised by a libertarian, anything-goes Internet. It's hard enough to stop "Star Wars" comment boards from devolving into flamebaiting, meme-generating files of NSFW Yodas.


So for now, we're still making our way through the Series of Tubes, and nobody knows where the boundaries lie. We joke, we grimace and we marvel at the creativity of the hive mind. The Internet is a big place, and countless cultures have set up residence. Eventually, what is now humor may lose its zing; what are now customs may become laws.


Will the rules ever become The Rules? Maybe some future generation will figure out the true guideposts of Internet life, and the singularity will be upon us.


Nah. It'll never happen.


What did we miss? Share your rules for the internet below in the comments. We'll feature some of the best on CNN.

2 firefighters dead, 2 hurt in Texas lodge fire

BRYAN, Texas Two Texas fire lieutenants have died of burns after battling a lodge hall fire, a city official said Saturday.

Greg Pickard and Eric Wallace, both with the department in the Central Texas city of Bryan, were in a group of firefighters responding to the blaze about midnight Friday at a Knights of Columbus hall, city spokeswoman Mary Lynne Stratta said.

The team entered the burning building but didn't emerge when ordered to evacuate, Stratta said.

Wallace, 36, died at the scene and Pickard, 54, on Saturday at a hospital in Galveston, she said.

"He called for help, said he was low on air," Stratta said of Wallace, a 13-year Bryan Fire Department veteran.

With Wallace still inside, Pickard and two other firefighters — Ricky Mantey Jr. and Mitchel Moran — were sent in to rescue him when the roof collapsed in flames, Fire Chief Randy McGregor said.

Rapid response units found the men inside the building. Mantey, 30, and Moran, 21, also were injured. They were taken to the Galveston hospital with burns. On Saturday, Stratta said they were both in serious but stable condition.

The Texas State Fire Marshal's office is investigating the cause of the fire in Bryan, about 90 miles northwest of Houston. A news release from the city said nothing was being held at the hall at the time.

"These four courageous individuals represent the best of the profession and are true heroes in every sense of the word," McGregor said.

Services for Wallace are scheduled for Thursday in Bryan, while those for Pickard, a 32-year veteran of the department, are pending.

Meteor Blast 'Something We Only Saw in Movies'












A day after a massive meteor exploded over this city in central Russia, a monumental cleanup effort is under way.


Authorities have deployed around 24,000 troops and emergencies responders to help in the effort.


Officials say more than a million square feet of windows -- the size of about 20 football fields -- were shattered by the shockwave from the meteor's blast. Around 4,000 buildings in the area were damaged.


The injury toll climbed steadily on Friday. Authorities said today it now stands at more than 1,200. Most of those injuries were from broken glass, and only a few hundred required hospitalization.


According to NASA, this was the biggest meteor to hit Earth in more than a century. Preliminary figures suggest it was 50 feet wide and weighed more than the Eiffel Tower.










SEE PHOTOS: Meteorite Crashes in Russia


NASA scientists have also estimated the force of the blast that occurred when the meteor fractured upon entering Earth's atmosphere was approximately 470 kilotons -- the equivalent of about 30 Hiroshima bombs.


Residents said today they still can't believe it happened here.


"It was something we only saw in the movies," one university student said. "We never thought we would see it ourselves."


Throughout the city, the streets are littered with broken glass. Local officials have announced an ambitious pledge to replace all the broken windows within a week. In the early morning hours, however, workers could still be heard drilling new windows into place.


Authorities have sent divers into a frozen lake outside the city, where a large chunk of the meteor is believed to have landed, creating a large hole in the ice. By the end of the day they had not found anything.


They are not the only ones looking for it.


Meteor hunters from around the world are salivating at what some are calling the opportunity of a lifetime. A small piece of the meteor could fetch thousands of dollars and larger chunks could bring in even hundreds of thousands.

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!"

Alleged cop killer died from single shot to head






LOS ANGELES: Alleged US cop killer Christopher Dorner died from a single gunshot wound to the head that appeared to be self-inflicted, a coroner said.

The doctor who examined the body concluded that "the cause of death was a single gunshot wound to the head," said San Bernardino County coroner Kevin Lacy, giving details from the results of a six-hour autopsy.

"We are not yet able to speak about the manner of death and tell you whether or not it was the result of a self-inflicted wound or another round," he told a press conference.

But he said, "while we are still assembling the reports and putting it together, the implication seems to be that the wound that took Christopher Dorner's life was self-inflicted."

The ex-Los Angeles Police Department (LAPD) cop went on the run last week after allegedly killing a couple and a policeman, and wounding three people. Another officer was killed and one wounded before the cabin in which Dorner was holed up burned in a fire.

Dorner had posted online a chilling manifesto in which he threatened to kill policemen and their families, and blamed the LAPD for treating him unfairly in his sacking in 2008.

The manhunt came to a climax Tuesday in a cabin near a snow-covered ski resort, after Dorner was spotted in a stolen vehicle and then fled on foot after crashing one vehicle and carjacking another.

San Bernardino County Sheriff John McMahon said that there was a prolonged firefight with the 33-year-old, who barricaded himself in the cabin after a six-day manhunt.

When they had exhausted other means, SWAT officers used a tractor-type device to open up the windows and walls of the cabin, and inserted a pyrotechnic chemical, to try to force Dorner to surrender.

A blaze erupted, starting at one corner of the cabin. As the flames took hold, after a period of no firing, "We heard a distinct single gunshot coming from inside the house," said McMahon.

The sound of it "indicated to me (that) a different kind of weapon had been fired," he added.

Facebook says it was hacked last month

Social media company Facebook announced Friday that it was hacked last month, which has led to an ongoing investigation.

Below is a statement issued by Facebook:

Last month, Facebook Security discovered that our systems had been targeted in a sophisticated attack. This attack occurred when a handful of employees visited a mobile developer website that was compromised. The compromised website hosted an exploit which then allowed malware to be installed on these employee laptops. The laptops were fully-patched and running up-to-date anti-virus software. As soon as we discovered the presence of the malware, we remediated all infected machines, informed law enforcement, and began a significant investigation that continues to this day. We have no evidence that Facebook user data was compromised in this attack.

Carnival Cruise Ship Hit With First Lawsuit












The first lawsuit against Carnival Cruise Lines has been filed and it is expected to be the beginning of a wave of lawsuits against the ship's owners.


Cassie Terry, 25, of Brazoria County, Texas, filed a lawsuit today in Miami federal court, calling the disabled Triumph cruise ship "a floating hell."


"Plaintiff was forced to endure unbearable and horrendous odors on the filthy and disabled vessel, and wade through human feces in order to reach food lines where the wait was counted in hours, only to receive rations of spoiled food," according to the lawsuit, obtained by ABCNews.com. "Plaintiff was forced to subsist for days in a floating toilet, a floating Petri dish, a floating hell."

The filing also said that during the "horrifying and excruciating tow back to the United States," the ship tilted several times "causing human waste to spill out of non-functioning toilets, flood across the vessel's floors and halls, and drip down the vessel's walls."


Terry's attorney Brent Allison told ABCNews.com that Terry knew she wanted to sue before she even got off the boat. When she was able to reach her husband, she told her husband and he contacted the attorneys.


Allison said Terry is thankful to be home with her husband, but is not feeling well and is going to a doctor.

"She's nauseated and actually has a fever," Allison said.


Terry is suing for breach of maritime contract, negligence, negligent misrepresentation and fraud as a result of the "unseaworthy, unsafe, unsanitary, and generally despicable conditions" on the crippled cruise ship.


"Plaintiff feared for her life and safety, under constant threat of contracting serious illness by the raw sewage filling the vessel, and suffering actual or some bodily injury," the lawsuit says.


Despite having their feet back on solid ground and making their way home, many passengers from the cruise ship are still fuming over their five days of squalor on the stricken ship and the cruise ship company is likely to be hit with a wave of lawsuits.


"I think people are going to file suits and rightly so," maritime trial attorney John Hickey told ABCNews.com. "I think, frankly, that the conduct of Carnival has been outrageous from the get-go."


Hickey, a Miami-based attorney, said his firm has already received "quite a few" inquiries from passengers who just got off the ship early this morning.


"What you have here is a) negligence on the part of Carnival and b) you have them, the passengers, being exposed to the risk of actual physical injury," Hickey said.


The attorney said that whether passengers can recover monetary compensation will depend on maritime law and the 15-pages of legal "gobbledygook," as Hickey described it, that passengers signed before boarding, but "nobody really agrees to."


One of the ticket conditions is that class action lawsuits are not allowed, but Hickey said there is a possibility that could be voided when all the conditions of the situation are taken into account.


One of the passengers already thinking about legal action is Tammy Hilley, a mother of two, who was on a girl's getaway with her two friends when a fire in the ship's engine room disabled the vessel's propulsion system and knocked out most of its power.


"I think that's a direction that our families will talk about, consider and see what's right for us," Hilley told "Good Morning America" when asked if she would be seeking legal action.

Sand-grain-sized drum extends reach of quantum theory


































The banging of a tiny drum heralds the intrusion of the weird world of quantum mechanics into our everyday experience. Though no bigger than a grain of sand, the drum is the largest object ever to have been caught obeying the uncertainty principle, a central idea in quantum theory.












As well as extending the observed reach of quantum theory, the finding could complicate the hunt for elusive gravitational waves : it suggests that the infinitesimal motion caused by these still-hypothetical ripples in spacetime could be overwhelmed by quantum effects.













The uncertainty principle says that you cannot simultaneously determine both a particle's exact position and momentum. For example, bouncing a photon off an electron will tell you where it is, but it will also change the electron's motion, creating fresh uncertainty in its speed.












This idea limits our ability to measure the properties of very small objects, such as electrons and atoms. The principle should also apply to everyday, macroscopic objects, but this has not been tested – for larger objects, the principle's effects tend to be swamped by other uncertainties in measurement, due to random noise, say.











Quantum drum













To extend the known reach of the uncertainty principle, Tom Purdy and colleagues of the University of Colorado, Boulder, created a drum by tightly stretching a 40-nanometre-thick sheet of silicon nitride over a square frame with sides of half a millimetre – about the width of a grain of sand. They placed the drum inside a vacuum chamber cooled to a few degrees above absolute zero, minimising any interference by random noise.












By continuously firing a stream of photons at the drum they were able to get increasingly precise measurements of the position of the skin at any moment. However, this also caused the skin to vibrate at an unknown speed. When they attempted to determine its momentum, the error in their measurement had increased – just as the uncertainty principle predicts.












"You don't usually have to think about quantum mechanics for objects you can hold in your hand," says Purdy.












That the uncertainty principle holds sway at such a large scale could affect the hunt for gravitational waves, which are predicted by Einstein's theory of general relativity but have never been detected.











Mitigation strategy












Gravitational wave detectors look for very slight changes in the distance between two test masses caused by passing spacetime ripples. Purdy says his team's experiment confirms long-held suspicions that quantum uncertainty could overwhelm these very small changes.













Now he and others can use the drum to explore more advanced measurement techniques to mitigate the effects. For example, uncertainty in an object's momentum could lead to future uncertainty in its position and there should be ways to minimise such knock-on effects. "You can't avoid the uncertainty principle, but you can in some clever ways make it [such that] increasing the momentum doesn't add back to the uncertainty in position at a later time," says Purdy.











His experiment is a neat demonstration of the breakdown of the traditional notion that the atomic world is quantum while the macroscopic world is classic, says Gerard Milburn of the University of Queensland in Brisbane, Australia, who was not involved in the work. Previous, attempts to blur the quantum-classical divide have involved entangling diamonds and demonstrating quantum superposition in a strip of metal.













Despite these feats, Milburn doesn't rule out the prospect of a breakdown on really large scales. "Of course maybe one day we will see quantum mechanics fail at some scale. Testing it to destruction is a good motivation for going down this path," he says.
