Armstrong Snubs Offer From Anti-Doping Officials

Lance Armstrong has turned down what may be his last chance at reducing his lifetime sporting ban.

Armstrong has already admitted in an interview with Oprah Winfrey to a career fueled by doping and deceit. But to get a break from the U.S. Anti-Doping Agency, all he had to do was tell his story to those who police sports doping. The deadline was today, and Armstrong now says he won't do it.

"For several reasons, Lance will not participate in USADA's efforts to selectively conduct American prosecutions that only demonize selected individuals while failing to address the 95 percent of the sport over which USADA has no jurisdiction," said Tim Herman, Armstrong's longtime lawyer. "Lance is willing to cooperate fully and has been very clear: He will be the first man through the door, and once inside will answer every question, at an international tribunal formed to comprehensively address pro cycling."

But the "international tribunal" Armstrong is anxious to cooperate with has one major problem: It doesn't exist.

The UCI, cycling's governing body, has talked about forming a "truth and reconciliation" commission, but the World Anti-Doping Agency has resisted, citing serious concerns about the UCI and its leadership.

WATCH: Armstrong's Many Denials Caught on Tape

U.S. Anti-Doping Agency officials seemed stunned by Armstrong's decision simply to walk away.

"Over the last few weeks, he [Armstrong] has led us to believe that he wanted to come in and assist USADA, but was worried of potential criminal and civil liability if he did so," said Travis Tygart, CEO of the U.S. Anti-Doping Agency. "Today, we learned from the media that Mr. Armstrong is choosing not to come in and be truthful and that he will not take the opportunity to work toward righting his wrongs in sport."

Armstrong's ongoing saga plays out amid a backdrop of serious legal problems.

Sources believe one reason Armstrong wants to testify to an international tribunal, rather than USADA, is because perjury charges don't apply if Armstrong lies to a foreign agency, they told ABC News.

While Armstrong has admitted doping, he has not given up any details, including the people and methods required to pull off one of the greatest scandals in all of sport.

Armstrong is facing several multimillion-dollar lawsuits right now, but his biggest problems may be on the horizon. As ABC News first reported, a high-level source said a criminal investigation is ongoing. And the Department of Justice also reportedly is considering joining a whistleblower lawsuit claiming the U.S. Postal Service was defrauded out of millions of dollars paid to sponsor Armstrong's cycling team.

Football: LionsXII impress Fandi in 2-2 draw with Johor

SINGAPORE: Fandi Ahmad was left shocked and impressed after his star-studded Johor Darul Takzim were forced to share the spoils at a packed Larkin Stadium, as they drew 2-2 with an impressive LionsXII side in the Malaysian Super League (MSL) on Tuesday night.

Fandi told reporters after the match that he and his players were shocked that the LionsXII had opted to go on the offensive from the start, saying that he had expected V Sundramoorthy's side to adopt "a more counterattacking strategy".

"This has been the best I've seen the LionsXII play," praised Fandi. "I'm also quite puzzled why my players couldn't rise to the occasion tonight and perform."

Indeed, there was a very different look to the LionsXII on Tuesday as they refused to sit back in the first half and often pressed forward in numbers in search of goals.

The LionsXII hardly looked in awe of Johor - who boast the likes of former Lazio player Simone Del Nero and former Spanish international Daniel Guiza - and impressed with fluid passing and hard tackling.

Their desire to draw first blood did not take long to pay dividends when Hariss Harun - who was playing his first match since he suffered a broken fibula in November - blasted the visitors into the lead after four minutes.

The Larkin Stadium was thoroughly silenced by the midfield lynchpin, but it was only for a moment.

Just six minutes later, Johor's livewire midfielder Nurul Azwan lost his marker and sent a low cross into the area which Del Nero superbly headed past goalkeeper Izwan Mahbud to score his first club goal.

Eager to reclaim the initiative, Sundram's charges continued to attack and were rewarded in the 37th minute when Baihakki Khaizan scored with a spectacular diving header following a free-kick.

The match continued to be played at a frenetic pace even after the restart and Fandi soon brought on even more firepower in Safee Sali.

With Safee, Guiza and Norshahrul Idlan Talaha now in attack, the LionsXII found themselves pegged back and digging deep to defend.

Fandi's decision to overload the attack eventually paid off as Norshahrul shrugged off tired LionsXII defenders and fired home Johor's equaliser from 20 yards out.

Despite not bagging the win, Sundram was satisfied with the result, praising his players for the tenacity they displayed.

He said: "I'm very happy the players fought for every ball tonight. The MSL is a very physical league and we've got to be able to fight hard on the field. Player to player, I'm very pleased that our boys can compete against Fandi's."

uBiome project to sequence the bacteria that live on us

Researchers will be testing swabs taken from thousands of paying volunteers.

(Credit:
uBiome Project)

Oxford University Ph.D. student Jessica Richman, who today finished raising some $350,000 from more than 2,500 people wanting to take part in the uBiome project, isn't shying away from reality: "Yes, we are going to be sampling people's poo," she told the Guardian this week.

And for the squeamish, she offered an asterisk: "You'll only have to wipe it on the toilet paper."

The uBiome project is a "citizen science" effort to sequence the genomes of the trillions of bacteria that colonize our bodies and likely play pivotal roles, both good and bad, in our health.

By sequencing the bacteria of volunteers (provided via Q-tips swabs of mouths, noses, ears, genitals, and guts) at a lab at the University of California in San Francisco, and then having volunteers log into a Web site to complete health surveys, Richman and her team hope to eventually understand what causes a range of health issues, from breast cancer and Crohn's to dementia and chronic obstructive pulmonary disease.

The uBiome project has far surpassed its original $100,000 goal (deadline was this morning). Apparently plenty of people are not afraid to sample their own feces.

And it turns out that sequencing the many strains of bacteria that live in and on our bodies -- known as the "microbiome" -- may be every bit as complicated as sequencing the human genome; after all, microbes outnumber human cells 10 to 1, according to the researchers.

The results may provide a good deal of information about the roots of various health issues given that "about 30 percent of the small molecules found in the blood come from the microbiome," Richman said. "So it certainly looks like some of the illnesses we see are linked to it."

Various studies are implicating specific strains of bacteria in a range of health outcomes, both good and bad. The science gets extremely complex, though, because the bacteria do not live in a vacuum and are interacting with other bacteria all the time.

Richman, who calls this "exploratory science," does not shy away from the challenge and hopes to discover correlations between bacteria strains and health outcomes to better understand both health and disease.

Meanwhile, volunteers who have paid into the project have the option to not only access details gleaned from their own, er, swabs, but to share that data if they choose. "Your data is yours -- you can download it, share it, do whatever you want with it," the team writes on its funding site. "We encourage you to opt-in to share your data with our scientists, but we respect your privacy and will not force you to do so. The data is also anonymized and private."

As for whom the researchers hoped would volunteer:

Everyone! skinny, fat, sick, healthy, Coke, Pepsi, Barack Obama, Mitt Romney, babies, grandmothers, lactose intolerant, gluten allergic, happy, sad, smoker, drinker, bald, vegan, smelly, bad breath, brown hair, blue eyes, blue hair, brown eyes, Atkins diet, high carb diet, sleepy, gassy, anxious, horny, asexual, smart, dyslexic, gorgeous, pregnant, and completely average. Babies, older people, women, men...everyone!

New Study Analyzes Heavy Metal Dancing

Parents may never understand their rock 'n' roll loving children, but scientists might. A study published online in arXiv this week seeks to explain the "mosh pit"—using physics.

To most scientists, heavy metal refers to elements on the lower end of the periodic table. But to Jesse Silverberg and Matt Bierbaum, doctoral students at Cornell University's department of Condensed Matter Physics, the aggressive music—and the violent dancing that accompanies it—could be a key to understanding extreme situations such as riots and panicked responses to disasters.

For the past two years, Silverberg and Bierbaum have studied "moshing," at heavy metal concerts, using theories of collective motion and the physical properties of gasses to better understand the chaos of metal fans' dancing.

Moshing, for those who have never attended a heavy metal show, is a form of dancing in which participants bump, jostle, and slam into one another. It's a form of social ritual that anthropologists have likened to spirit possession in its uncontrolled, dynamic, and often violent nature.

Silverberg and Bierbaum say it can also be understood by applying models of gaseous particles. As these particles float in groups, they too run, bash, and slam into each other, sending the elements flying in chaotic patterns.

"We are interested in how humans behave in similar excited states," said Silverberg, "but it's not exactly ethical to start a riot for research."

Extreme Physics

Mosh pits provided the scientists with a way to observe excited collective movement without causing undue injury or death. Analyzing hours of recorded footage from concerts and making multiple field trips to music clubs, Silverberg and Bierbaum recognized the particulate physical patterns in the mosh pit.

Further, they differentiated two distinct forms of heavy metal dancing: the "mosh pit" itself, which follows the gaseous pattern, and the "circle pit" (where dancers run, smash, and dance in a circular rotation) within it, which adheres to a vortex pattern of particulate behavior.

Based on these observations, they created an interactive computer model depicting the behavior.

Animal Instincts

"Herd animals behave in very similar spirit—what physicists call 'flocking' behavior," said Bierbaum. (See "The Genius of Swarms," from the July 2007 issue of National Geographic magazine.)

As with groups of flying birds or schooling fish, simple rules can be applied to individuals in large groups—like moshers—to understand what seems to be very complex behavior. This makes modeling possible, allowing computers to re-create immense numbers of actions in a matter of seconds. These models can then be used to design spaces that would minimize trampling or injury, or to tailor responses to disasters like fires.

"The lessons we've learned in mosh pits [could be used] to build better stadiums, or movie theaters," Silverberg said.

James Sethna, one of the researchers' advising professors, hastened to add that his students' forays into heavy metal science "didn't start out for reasons of creating safer stadiums. We did it because it was cool and we wanted to know if we could explain human behavior—albeit slightly intoxicated behavior—without having to use complex [models]."

A longtime heavy metal fan himself, Silverberg shared which band produced the best results: "Killswitch Engage ... always gets the crowd nuts. Although of course everyone has their own favorites."

Report Fingers Chinese Military Unit in US Hacks

A Virginia-based cyber security firm has released a new report alleging a specific Chinese military unit is likely behind one of the largest cyber espionage and attack campaigns aimed at American infrastructure and corporations.

In the report, released today by Mandiant, China's Unit 61398 is blamed for stealing "hundreds of terabytes of data from at least 141 organizations" since 2006, including 115 targets in the U.S. Twenty different industrial sectors were targeted in the attacks, Mandiant said, from energy and aerospace to transportation and financial institutions.

Mandiant believes it has tracked Unit 61398 to a 12-story office building in Shanghai that could employ hundreds of workers.

"Once [Unit 61398] has established access [to a target network], they periodically revisit the victim's network over several months or years and steal broad categories of intellectual property, including technology blueprints, proprietary manufacturing processes, test results, business plans, pricing documents, partnership agreements, and emails and contact lists from victim organizations' leadership," the report says.

The New York Times, which first reported on the Mandiant paper Monday, said digital forensic evidence presented by Mandiant pointing to the 12-story Shangai building as the likely source of the attacks has been confirmed by American intelligence officials. Mandiant was the firm that The Times said helped them investigate and eventually repel cyber attacks on their own systems in China last month.

The Chinese government has repeatedly denied involvement in cyber intrusions and Chinese Foreign Ministry spokesperson Hong Lei said today that the claims in the Mandiant report were unsupported, according to a report by The Associated Press.

"To make groundless accusations based on some rough material is neither responsible nor professional," he reportedly said.

Mandiant's report was released a week after President Obama said in his State of the Union address that America must "face the rapidly growing threat from cyber attack."

"We know hackers steal people's identities and infiltrate private e-mail. We know foreign countries and companies swipe our corporate secrets. Now our enemies are also seeking the ability to sabotage our power grid, our financial institutions, and our air traffic control systems. We cannot look back years from now and wonder why we did nothing in the face of real threats to our security and our economy," he said.

Though Obama did not reference China or any country specifically, U.S. officials have previously accused the Asian nation of undertaking a widespread cyber espionage campaign.

Referring to alleged Chinese hacking in October 2011, House Intelligence Committee Chairman Rep. Mike Rogers (R-Mich.) said in an open committee meeting that he did not believe "that there is a precedent in history for such a massive and sustained intelligence effort by a government agency to blatantly steal commercial data and intellectual property."

Rogers said that cyber intrusions into American and other Western corporations by hackers working on behalf of Beijing -- allegedly including attacks on corporate giants like Google and Lockheed Martin -- amounted to "brazen and widespread theft."

"The Chinese have proven very, very good at hacking their way into very large American companies that spend a lot of money trying to protect themselves," cyber security expert and ABC News consultant Richard Clarke said in an interview last week.

Biofuel rush is wiping out unique American grasslands

Say goodbye to the grass. The scramble for biofuels is rapidly killing off unique grasslands and pastures in the central US.

Christopher Wright and Michael Wimberly of South Dakota State University in Brookings analysed satellite images of five states in the western corn belt. They found that 530,000 hectares of grassland disappeared under blankets of maize and soya beans between 2006 and 2011. The rate was fastest in South Dakota and Iowa, with as much as 5 per cent of pasture becoming cropland each year.

The trend is being driven by rising demand for the crops, partly through incentives to use them as fuels instead of food.

The switch from meadows to crops is causing a crash in populations of ground-nesting birds. One of the US's most important breeding grounds for wildfowl, an area called the Prairie Pothole Region, is also at risk, with South Dakota's crop fields now within 100 metres of the wetlands. "Half of North American ducks breed here," says Wright.

Bill Henwood of the Temperate Grasslands Conservation Initiative in Vancouver, Canada, says the results are distressing. "Exchanging real environmental impacts for the dubious benefits of biofuels is counterproductive," he says. "Last year's record drought in the corn belt all but wiped out the crops anyway."

Greater US military role in Mali likely after polls: senator

BAMAKO: The United States is likely to play a more active military role in Mali, where French-led forces are battling Islamist rebels, after the country holds elections, the chair of a key Senate sub-committee said Monday.

Washington has been providing intelligence, transport and mid-air refuelling to France, which launched its intervention last month, but cannot work directly with the Malian army until a democratically elected government replaces current leaders who came to power after a coup, said Christopher Coons, chair of the Senate foreign relations committee's Africa sub-committee.

"There is the hope that there will be additional support from the United States in these and other areas, but ... American law prohibits direct assistance to the Malian military following the coup," Coons told journalists in the Malian capital.

"After there is a full restoration of democracy, I would think it is likely that we will renew our direct support for the Malian military," added the senator, who led a bipartisan congressional delegation to Mali to meet with interim president Dioncounda Traore and French and African defence officials.

US military aid to Mali before the March 2012 coup consisted largely of training and equipment such as vehicles, a State Department official said.

But military assistance "would obviously be resumed in a way commensurate with the current needs. Priorities would have shifted a bit," the official added.

"There could be other kinds of assistance that had there not been a coup we could have provided, or requests for things now that we can't provide."

Some US lawmakers criticised President Barack Obama's administration last week for not doing more to help France in Mali.

"This is a NATO ally fighting Al-Qaeda-linked terrorists -- it shouldn't be that hard," said House foreign affairs committee chairman Ed Royce.

The hint of greater US involvement after elections adds to the complicated calculus of picking a date for the polls.

Traore, the interim president, has said he wants elections by July 31.

But critics say that is too soon given the problems Mali still faces, including ongoing insurgent attacks, a deeply divided military and hundreds of thousands of people who have fled their homes.

The minister responsible for organising the elections, Territorial Administration Minister Moussa Sinko Coulibaly, said last week the timeline "can be changed if necessary".

France, which launched its intervention on January 11 as Al-Qaeda-linked groups that had occupied the north for 10 months made incursions into government territory, is keen to share the military burden in Mali, and has announced plans to start bringing its 4,000 troops home in March.

The European Union formally approved a military training mission Monday that will be tasked with getting Mali's under-funded army ready to secure reclaimed territory.

But France is the only Western country with combat troops on the ground, and would like to hand over to some 6,000 west African troops who are slowly being deployed to help.

Mali imploded after a coup by soldiers who blamed the government for the army's humiliation at the hands of separatist rebels in the north.

With the capital in disarray, Al-Qaeda-linked fighters hijacked the independence rebellion and took control of a territory larger than Texas.

Ubuntu just went 1080p on Dell's sleekest laptop.

The 2.99-pound XPS 13 Developer Edition laptop is now available on Dell's site for $1,549.

Those specifications, with the critical exception of the Ubuntu Linux, are identical to the 1080p XPS 13 for
Windows 8.

Here are the specs:

• Operating system: Ubuntu Linux 12.04 LTS
  
• Display: 13.3-inch 1,920x1,080 panel
  
• Processor: 3rd Generation Intel Core i7-3537U
  
• Memory: 8GB2 DDR3 SDRAM at 1600MHz
  
• Storage: 256GB solid-state drive
  
• Graphics: Intel HD 4000
  
• Price: $1,549
  

In addition to the U.S., Dell will also start to roll it out in select countries in Europe, including the UK, France, Germany, Austria, Belgium, Denmark, and Finland.

The XPS 13 is one of the better ultrabook designs to emerge from a top-tier PC vendor. It squeezes a 13.3-inch screen into a footprint more typical of 12-inch laptops, boasts Gorilla Glass, and is constructed from aluminum and carbon fiber, allowing Dell to keep the weight to just under three pounds.

The upgraded display is also brighter and has wider viewing angles that the original 1,366x768 XPS 13 model.

Confirmed: Dogs Sneak Food When People Aren't Looking

Many dog owners will swear their pups are up to something when out of view of watchful eyes. Shoes go missing, couches have mysterious teeth marks, and food disappears. They seem to disregard the word "no."

Now, a new study suggests dogs might understand people even better than we thought. (Related: "Animal Minds.")

The research shows that domestic dogs, when told not to snatch a piece of food, are more likely to disobey the command in a dark room than in a lit room.

This suggests that man's best friend is capable of understanding a human's point of view, said study leader Juliane Kaminski, a psychologist at the U.K.'s University of Portmouth.

"The one thing we can say is that dogs really have specialized skills in reading human communication," she said. "This is special in dogs." (Read "How to Build a Dog.")

Sneaky Canines

Kaminski and colleagues recruited 84 dogs, all of which were more than a year old, motivated by food, and comfortable with both strangers and dark rooms.

The team then set up experiments in which a person commanded a dog not to take a piece of food on the floor and repeated the commands in a room with different lighting scenarios ranging from fully lit to fully dark.

They found that the dogs were four times as likely to steal the food—and steal it more quickly—when the room was dark. (Take our dog quiz.)

"We were thinking what affected the dog was whether they saw the human, but seeing the human or not didn't affect the behavior," said Kaminski, whose study was published recently in the journal Animal Cognition.

Instead, she said, the dog's behavior depended on whether the food was in the light or not, suggesting that the dog made its decision based on whether the human could see them approaching the food.

"In a general sense, [Kaminski] and other researchers are interested in whether the dog has a theory of mind," said Alexandra Horowitz, head of the Dog Cognition Lab at Barnard University, who was not involved in the new study.

Something that all normal adult humans have, theory of mind is "an understanding that others have different perspective, knowledge, feelings than we do," said Horowitz, also the author of Inside of a Dog.

Smarter Than We Think

While research has previously been focused on our closer relatives—chimpanzees and bonobos—interest in dog cognition is increasing, thanks in part to owners wanting to know what their dogs are thinking. (Pictures: How smart are these animals?)

"The study of dog cognition suddenly began about 15 years ago," Horowitz said.

Part of the reason for that, said Brian Hare, director of the Duke Canine Cognition Lab and author of The Genius of Dogs, is that "science thought dogs were unremarkable."

But "dogs have a genius—years ago we didn't know what that was," said Hare, who was not involved in the new research. (See pictures of the the evolution of dogs, from wolf to woof.)

Many of the new dog studies are variations on research done with chimpanzees, bonobos, and even young children. Animal-cognition researchers are looking into dogs' ability to imitate, solve problems, or navigate social environments.

So just how much does your dog understand? It's much more than you—and science—probably thought.

Selectively bred as companions for thousands of years, dogs are especially attuned to human emotions—and, study leader Kaminski said, are better at reading human cues than even our closest mammalian relatives.

"There has been a physiological change in dogs because of domestication," Duke's Hare added. "Dogs want to bond with us in ways other species don't." (Related: "Dogs' Brains Reorganized by Breeding.")

While research reveals more and more insight into the minds of our furry best friends, Kaminski said, "We still don't know just how smart they are."
