Astronomers discover largest known structure in the universe

(Reuters) – Astronomers have discovered the largest known structure in the universe – a group of quasars so large it would take 4 billion years to cross it while traveling at speed of light.

The immense scale also challenges Albert Einstein’s Cosmological Principle, the assumption that the universe looks the same from every point of view, researchers said.

The findings by academics from Britain’s University of Central Lancashire were published in the journal Monthly Notices of the Royal Astronomical Society and reported on the society’s website on Friday.

Quasars are believed to be the brightest objects in the universe, with light emanating from the nuclei of galaxies from the early days of the universe and visible billions of light-years away.

“Since 1982 it has been known that quasars tend to group together in clumps or ‘structures’ of surprisingly large sizes, forming large quasar groups or LQGs,” the society said.

This newly discovered large quasar group has a dimension of 500 megaparsecs, each megaparsec measuring 3.3 million light-years.

Because the LQG is elongated, its longest dimension is 1,200 megaparsecs, or 4 billion light-years, the society said.

That size is 1,600 times larger than the distance from Earth’s Milky Way to the nearest galaxy, the Andromeda.

“While it is difficult to fathom the scale of this LQG, we can say quite definitely it is the largest structure ever seen in the entire universe,” Roger Clowes, leader of the research team, said in a statement. “This is hugely exciting – not least because it runs counter to our current understanding of the scale of the universe.”

Clowes said the team would continue to investigate the phenomenon with particular interest in the challenge to the Cosmological Principle, which has been widely accepted since Einstein, whose work still forms the basis for much of modern cosmology.

STORY HIGHLIGHTS

• Mike Downey: I haven't a smidgen of sympathy for the dope "pedaler"


• Randy Cohen: If many cycling fans are right, most of the top riders engaged in doping


• Jeff Pearlman: Lance racing again is not truly an option anyway -- he's almost 42


• John Hoberman: Any lifting of his lifetime ban should be based on his total cooperation

(CNN) -- CNN asked for views on whether disgraced cyclist Lance Armstrong deserves another chance in light of his apologies to his charity, Livestrong, and his soon-to-be-aired interview with Oprah Winfrey, in which it's widely reported he admitted he used performance-enhancing drugs. Armstrong is banned from professional cycling for life and was stripped of his seven Tour de France titles.

Mike Downey: No sympathy for the dope "pedaler"

I was at the Champs-Elysees finish line on July 27, 1986, when the bike of Greg LeMond whizzed by, making him the first American to win the Tour de France. It was a monumental achievement: 210 cyclists, 23 grueling days, long and winding roads, treacherously steep hills.

Mike Downey

Equally hard had to be the abuse LeMond endured in retirement after publicly decrying the sport's hypocrisies and daring to suggest that seven-time winner Lance Armstrong, the All-American boy himself, had not been on the up-and-up. Vilified and disdained, LeMond was treated like a tobacco company's insider who blew the whistle on the industry's methods or like Carl Lewis speculating that his rival Ben Johnson had not won foot races fairly and squarely. As if he had an ax to grind.

I haven't a smidgen of sympathy for Armstrong now that he is exposed for the dope-pedaler -- that's pedal, not peddle -- he truly was. He played the Jean Valjean part of the persecuted man for every franc that it was worth. Let us resist the magnanimous gesture to forgive, forget and give Lance a second (eighth?) chance. He was caught, unlike certain baseball players who have been merely suspected or accused, and has, evidently, confessed. Seven strikes and you're out.

Professional athletes do exist who 'fess up, serve a suspension, then are welcomed back. They, as with the ballplayers, did disgrace their life's work, yet none single-handedly won their sport's championship with their chicanery. None stood apart as Armstrong did and hogged credit for being a champion, a hero. None won a championship by compelling teammates to also cheat, at risk of being shunned, smeared or dropped from the team.

I say we say goodbye for good to Monsieur Armstrong, farewell, adieu. Off to Elba and exile with you, you rogue. Vive LeMond.

Mike Downey is a former columnist for The Los Angeles Times and Chicago Tribune.

Randy Cohen: All big-time cyclists who doped should confess

The important ethical question isn't whether Lance deserves a second chance. Chance to do what? Cheat in seven more Tours? Lie about it seven more times? Bully seven more teammates into doping? He behaved badly and is rightly censured.

Randy Cohen

But that should be the beginning, not the end, of this disheartening story. There's a lot more blame to go around. Cycling's governing bodies also have an ethical duty, and that's to provide a setting in which honest athletes can participate.

If many cycling fans are right, most of the top riders engaged in doping. You simply can't compete against them without doing the same. What was Lance to do? Quit the sport? And who inherits his Tour titles? Some other cheat?

It would be thrilling if one by one, they declined in a Spartacus moment -- an honest, I-am-drugged-Spartacus moment. This is a community problem; it demands community solutions. Unless those who run big-time cycling institute real reforms, Lance's fall will be merely a celebrity scandal, and there's little good in that.

Randy Cohen wrote The Ethicist column in The New York Times Magazine till 2011, and he is a former writer for "Late Night With David Letterman." His latest book is "Be Good: How to Navigate the Ethics of Everything."

Jeff Pearlman: He's almost 42, forget about it

Back when I was 8 or 9, my parents took me to my first trip to Disney World. I remember Space Mountain, and I remember Mickey Mouse's enormous head. For some reason, though, what I remember most is a sign posted within the borders of Epcot. It read: If you can dream it, you can do it.

"Dad," I said, "I dream of being 8-feet tall. But that'll never happen ..."

"Well, son ..."

Jeff Pearlman

"And, Dad, I dream of being able to fly just like Superman. But that'll never happen ..."

"Son, the thing is ..."

"And Dad, I'd really like to win an Olympic gold medal for my Joanie Cunningham impersonation, but ..."

"Son," my father said, "It's a sign. It's just a damn sign."

Sigh.

Throughout Lance Armstrong's recent fight to prove he hadn't cheated, and throughout the plights of Barry Bonds and Roger Clemens and Mark McGwire and the alleged PED abuses of dozens upon dozens of others, I've often thought about that day at Disney and, specifically, of that sign.

As a boy, it spoke to me as a kid longing for greatness. Maybe, just maybe, I can accomplish anything. Maybe ...

As a sportswriter who has chronicled much of the past two decades, however, it strikes me as foolish nonsense. As Armstrong's recent admission shows, the words must be altered to -- if you can dream it, you can do it -- as long as you leave your ethics at the door and cheat your ass off and don't mind throwing your supporters under a bus.

That, now, is the sad, pathetic legacy of men such as Armstrong and Bonds. Once upon a time, they dreamed of doing wonderful things: Of hitting baseballs 500 miles; of speeding down the largest mountains; of being special. Then, however, they learned (as we all do) that we are bound by the confines of humanity. Within the rules and regulations, there is only so strong. There is only so fast. There is only so big. Hence, one can either accept his lot in life and put out the best possible effort, or he can cheat and lie and enjoy the temporary fruits while trying to avoid the inevitable plummet.

Do I think he should be allowed to race again? No. Lance Armstrong racing again is not truly an option anyway -- he's almost 42.

Just the same, I am thrilled that he has -- at long last -- begun to come clean. There are lessons to be learned here, beyond those pertaining to cycling. And day's end, when the cheering has stopped, there is something to be said for trying your best, even if your best doesn't result in triumph.

There is empowerment in knowing you gave your all. There is satisfaction in achieving your own PR. There is the sense of community and camaraderie that comes in the aftermath of a sporting event. Cold beers, casual conversation, sore muscles -- bliss.

Armstrong and Bonds forgot that long ago. For them, it was all -- and only --about winning. They got lost in a corrupt world of enhancers and boosters and had their heads turned by the fame and accolades and money.

Now, though, they are outcasts. They are the tombstones of long-ago dreams.

Wayne Norman: Like a convenience store robbery that goes wrong

Lance knows that a quick mea culpa is not enough -- otherwise, he would have admitted to doping long ago. Instead, he made a calculated gamble that he could preserve his reputation and brand by lying, defrauding corporate sponsors, impugning the authorities pursuing him and actively slandering and suing honest whistle-blowers who stood in his way.

Wayne Norman

That bet has not paid off.

Like a convenience store robbery that goes wrong and leads to a hostage-taking and a high-speed chase, Lance's doping is by far the least of his transgressions. A highly calculated confession about the doping still looks like Lance gambling to advance his interests. Former fans will need contrition and a sense that he genuinely regrets the gamble. Those he slandered and defrauded should demand even more.

Lance cannot get another chance as an athlete at this point. That would make a mockery of all sporting rules and their enforcement. When you've been that blatantly dishonest, it won't be easy to convince people to trust you again.

Wayne Norman is the Mike & Ruth Mackowski professor of ethics at Duke University.

John Eustice: Armstrong can make a deal and get leeway

What Lance has, the U.S. Anti-Doping Agency wants, and Lance is not going to give it to them unless he gets his (athletic) life back. USADA knows that Lance stands at the nexus of two distinct cultures, two completely different mindsets: The ideals and dreams of Olympic sport and the harsh, ratings-driven business of the professional game.

John Eustice

They view this conquest of Lance as their great chance to have the Olympic vision triumph over the cynicism of the pros. But they need his cooperation to win.

Despite the admitting of pros into the Olympic Games, in truth, the two cultures do not mesh. Pro sports are businesses where talent, ratings and the subsequent cash flows from them, must be protected just as in any other entertainment business.

USADA needs to understand how the professional mentality has "infected" the Olympic movement, and Lance is the key. Was he protected by the International Cycling Union? Was the Tour de France involved? Did it go even higher that that?

USADA makes deals. If Lance can provide them with information on the underground system that fuels athletes worldwide, and explain, for example, how of the 6,000 drugs tests given at the London Games, only one came back positive, allowing him to participate in some triathlons seems a very small price to pay.

Cycling analyst John Eustice was one of the pioneer Americans to break into the world of European pro cycling. He co-founded and captained the first American team to race in the Tour of Italy, and is a two-time United States Professional Champion.

John Hoberman: Is it possible to acquire a conscience overnight?

The report that Lance Armstrong choked up during his apology to Livestrong Foundation employees earlier this week would seem to mark an abrupt departure from the cold, calculating and manipulative personality he has displayed throughout his celebrated athletic career.

Having closely followed the Armstrong saga as a doping researcher, I have come to doubt whether this is man is capable of genuine contrition. One can only imagine the apologetic telephone calls he has been making to the former teammates and other victims he persecuted, threatened, bullied and slandered over so many years.

John Hoberman

Is it really possible to acquire a conscience overnight? Can a person who has long-demonstrated reckless self-assertion, a lack of empathy, coldheartedness, egocentricity, superficial charm and irresponsibility suddenly repent after months of hostile intransigence?

One is tempted to say no, since this ensemble of traits bears a disturbing similarity to the psychopathic personality. Let us hope that Armstrong is capable of leaving his old self behind and building a healthier personal identity.

Any lifting of his lifetime ban from officially recognized competitions should be made contingent on his absolute and total cooperation with the United States Anti-Doping Agency and the World Anti-Doping Agency. Armstrong must demonstrate some good faith by revealing everything he knows about the illicit trade in doping drugs as well as the cynical and opportunistic doctors who have profited from these corrupt arrangements.

John Hoberman teaches at the University of Texas at Austin and is the author of "Mortal Engines: The Science of Performance and the Dehumanization of Sport." He was a consultant in 2005 for the SCA Promotions of Dallas, the insurance company demanding that Lance Armstrong repay a total of $7.5 million it paid to him in Tour de France bonuses.

Shawn Klein: If he cooperates, maybe the lifetime ban could be reduced

After years of adamant denials and protestations of his innocence, Lance Armstrong has reportedly come forward to admit his use of prohibited performance enhancing drugs. If Armstrong is sincerely contrite and forthright in his apology, most people, including myself, will forgive him for his use of prohibited drugs.

Shawn Klein

He cheated in a sport known for its widespread cheating; that doesn't justify his use but it does put his actions into an understandable context that makes it easier to excuse the use. Further, if Armstrong cooperates with the U.S. Anti-Doping Agency, his lifetime ban from cycling ought to be reduced to something more reasonable.

The more troubling aspects of the Armstrong case are the allegations that he harassed and intimidated team members and potential whistle-blowers. Violating the arbitrary rules of a sport shows a character flaw and poor judgment, but it is hard to see who else is truly harmed by such actions. But to threaten, intimidate and coerce others (either to use performance enhancing drugs themselves or to cover up his team's use) causes real harm.

Even if only some of these reports are accurate, Armstrong will have to do more than sit on Oprah's couch to earn forgiveness.  Shawn Klein teaches at the Department of Philosophy and Center for Ethics and Entrepreneurship at Rockford College in Illinois and writes the Sportsethicist blog.

Japanese airlines ground Boeing 787s after emergency landing

TOKYO (Reuters) - Japan's two leading airlines grounded their fleets of Boeing 787s on Wednesday after one of the Dreamliner passenger jets made an emergency landing, the latest and most serious in a series of incidents to heighten safety concerns over a plane many see as the future of commercial aviation.

All Nippon Airways Co said instruments aboard a domestic flight indicated a battery error, triggering emergency warnings to the pilots. It said the battery in the forward cargo hold was the same lithium-ion type as one involved in a fire on another Dreamliner at a U.S. airport last week.

The carrier grounded all 17 of its 787s, and Japan Airlines Co suspended its 787 flights scheduled for Wednesday. ANA said its planes could be back in the air as soon as Thursday once checks were completed. The two carriers operate around half of the 50 Dreamliners delivered by Boeing to date.

Wednesday's incident, described by a transport ministry official as "highly serious" - language used in international safety circles as indicating there could have been an accident - is the latest in a line of mishaps - fuel leaks, a battery fire, wiring problem, brake computer glitch and cracked cockpit window - to hit the world's first mainly carbon-composite airliner in recent days.

"I think you're nearing the tipping point where they need to regard this as a serious crisis," said Richard Aboulafia, a senior analyst with the Teal Group in Fairfax, Virginia. "This is going to change people's perception of the aircraft if they don't act quickly."

The 787, which has a list price of $207 million, represents a leap in the way planes are designed and built, but the project has been plagued by cost overruns and years of delays. Some have suggested Boeing's rush to get planes built after those delays resulted in the recent problems, a charge the company strenuously denies.

Both the U.S. Federal Aviation Administration (FAA) and the National Transportation Safety Board (NTSB) said they were monitoring the latest incident as part of a comprehensive review of the Dreamliner announced late last week.

ALARM TRIGGERED

ANA flight 692 left Yamaguchi Airport in western Japan shortly after 8 a.m. local time (2300 GMT Tuesday) bound for Haneda Airport near Tokyo, a 65-minute flight. About 18 minutes into the flight, at 30,000 feet, the plane began a descent, cutting its altitude to 20,000 feet in about four minutes. It made an emergency landing 16 minutes later, according to flight-tracking website Flightaware.com.

A spokesman for Osaka airport authority said the plane landed at Takamatsu at 8:45 a.m. All 129 passengers and eight crew evacuated via the plane's inflatable chutes. Chief Cabinet Secretary Yoshihide Suga said five people were slightly injured.

At a news conference - where ANA's vice-president Osamu Shinobe bowed deeply in apology - the carrier said a battery in the forward cargo hold triggered emergency warnings to the pilots, who decided on the emergency action.

"There was a battery alert in the cockpit and there was an odd smell detected in the cockpit and cabin, and (the pilot) decided to make an emergency landing," Shinobe said.

Passengers leaving the ANA flight told local TV there was an odor like burning plastic on the plane as soon as it took off. "There was a bad smell as soon as we started and before we made the emergency landing there was an announcement and the stewardess' voice was shaking, so I thought this was serious," one passenger told TBS TV.

Shigeru Takano, a senior safety official at the Civil Aviation Bureau, said that an emergency light indicating a malfunction had gone off in the cockpit, followed by another warning light indicating smoke. Checks showed a battery error and smoke was smelled in the cockpit, he added.

One man told a local broadcaster there was a burning smell in the plane. "There was a strong, burning smell, but the smoke appeared after they opened the emergency doors, after we landed," he said.

Marc Birtel, a Boeing spokesman, told Reuters: "We've seen the reports, we're aware of the events and are working with our customer."

UNDER REVIEW

In Asia, only the Japanese and Air India have the Dreamliner in service, but other airlines are among those globally to have ordered around 850 of the new aircraft.

Australia's Qantas Airways said its order for 15 Dreamliners remained on track, with its Jetstar subsidiary due to take delivery of the first of the aircraft in the second half of this year.

France to stay in Mali until stability restored

BAMAKO/DUBAI (Reuters) - France pledged on Tuesday to keep troops in Mali until stability returned to the West African country, raising the specter of a long campaign against al Qaeda-linked rebels who held their ground despite a fifth day of air strikes.

Paris has poured hundreds of soldiers into Mali and carried out 50 bombing raids since Friday in the Islamist-controlled northern half of the country, which Western and regional states fear could become a base for terrorist attacks in Africa and Europe.

Defense Minister Jean-Yves Le Drian said that, despite French air support, Malian forces had not been able to dislodge Islamist fighters from the central Malian towns of Konna or Diabaly, just 350 km (220 miles) northeast of Bamako.

A column of French armored vehicles rolled northward from the dusty riverside capital of Bamako towards rebel lines on Tuesday, the first major northward deployment of ground troops. A military official declined to comment on their objective.

Thousands of African soldiers are due to take over the offensive. Regional armies are scrambling to accelerate an operation which was initially not expected until September and has been brought forward by France's surprise bombing campaign aimed at stopping a rebel advance on a strategic town last week.

President Francois Hollande, on a visit to the United Arab Emirates during which he sought Gulf states' financial backing for the African-led mission, suggested France would retain a major role in its former colony for months to come.

"We have one goal. To ensure that when we leave, when we end our intervention, Mali is safe, has legitimate authorities, an electoral process and there are no more terrorists threatening its territory," Hollande told a news conference.

Paris has said it plans to deploy 2,500 soldiers to bolster the Malian army and work with the intervention force provided by West African states.

AFRICAN TROOPS

West African Defense chiefs met in Bamako on Tuesday to approve plans for the swift deployment of 3,300 regional troops, foreseen in a United Nations-backed intervention plan. After failing to reach a final agreement, they adjourned their talks until Wednesday.

Nigeria pledged to deploy soldiers within 24 hours, and Belgium said it was sending transport planes and helicopters to help, but West Africa's armies need time to become operational.

Mali's north, a vast and inhospitable area of desert and rugged mountains the size of Texas, was seized last year by an Islamist alliance combining al Qaeda's north African wing AQIM with splinter group MUJWA and the home-grown Ansar Dine rebels.

Any delay in following up on the French air bombardments of Islamist bases and fuel depots with a ground offensive could allow the insurgents to slip away into the desert and mountains, regroup and counter-attack.

The rebels, who French officials say are mobile and well armed, have shown they can hit back, dislodging government forces from Diabaly on Monday.

Residents said the town was still under Islamist control on Tuesday despite a number of air strikes that shook houses.

An eye witness near Segou, to the south, told Reuters he had seen 20 French Special Forces soldiers driving toward Diabaly.

In Konna, whose seizure on Thursday sparked French involvement, residents said Islamist fighters were camped just outside town. Army troops had also withdrawn after entering the town on Saturday.

Malians have largely welcomed the French intervention, having seen their army suffer a series of defeats by the rebels.

"With the arrival of the French, we have started to see the situation on the front evolve in our favor," said Aba Sanare, a resident of Bamako.

QUESTIONS OVER READINESS

Aboudou Toure Cheaka, a senior regional official in Bamako, said the West African troops would be on the ground in a week.

The original timetable for the 3,300-strong U.N.-sanctioned African force - to be backed by western logistics, money and intelligence services - did not initially foresee full deployment before September due to logistical constraints.

Senegal, Burkina Faso, Niger, Nigeria and Guinea have all offered troops. Col. Mohammed Yerima, spokesman for Nigeria's Defense ministry, said the first 190 soldiers would be dispatched within 24 hours.

But Nigeria, which is due to lead the mission, has already cautioned that even if some troops arrive in Mali soon, their training and equipping will take more time.

Sub-Saharan Africa's top oil producer, which already has peacekeepers in Sudan's Darfur and is fighting a bloody and difficult insurgency at home against Islamist sect Boko Haram, could struggle to deliver on its troop commitment of 900 men.

One senior government adviser in Nigeria said the Mali deployment was stretching the country's military.

"The whole thing's a mess. We don't have any troops with experience of those extreme conditions, even of how to keep all that sand from ruining your equipment. And we're facing battle-hardened guys who live in those dunes," said the adviser, who asked not to be named.

FRENCH LINING UP SUPPORT

France, which has repeatedly said it has abandoned its role as policeman of its former African colonies, said on Monday that the U.S., Canada, Denmark and Germany had also offered logistical support.

Fabius has said Gulf Arab states would help the Mali campaign, while Belgium said on Tuesday it would send two C130 transport planes and two medical helicopters following a request from Paris.

A meeting of donors for the operation was expected to be held in Addis Ababa at the end of January.

Security experts have warned that the multinational intervention in Mali, couched in terms of a campaign by governments against "terrorism", could provoke a jihadist backlash against France and the West, and African allies.

U.S. officials have warned of links between AQIM, Boko Haram in Nigeria and al Shabaab Islamic militants fighting in Somalia.

Al Shabaab, which foiled a French effort at the weekend to rescue a French secret agent it was holding hostage, urged Muslims around the world to rise up against what it called "Christian" attacks against Islam.

"Our brothers in Mali, show patience and tolerance and you will win. War planes never liberate a land," Sheikh Ali Mohamud Rage, al Shabaab's spokesman, said on a rebel-run website.

U.S. officials said Washington was sharing information with French forces in Mali and considering providing logistics, surveillance and airlift capability.

"We have made a commitment that al Qaeda is not going to find any place to hide," U.S. Defense Secretary Leon Panetta told reporters as he began a visit to Europe. Panetta later said the U.S. had no plans to send troops to Mali.

One U.S. military source said the haphazard nature of French involvement reminded him of the U.S. entry into Afghanistan.

"I don't know what the French endgame is for this," the source said. "Air strikes are fine, but pretty soon you run out of easy targets. Then what do you do? What do you do when they head up into the mountains?"

Apple drags on S&P, Nasdaq; Dell jumps after report

NEW YORK (Reuters) - The S&P 500 and Nasdaq ended lower on Monday as worries over demand for Apple products drove down its shares and investors braced for earnings disappointments.

Running counter to that was Dell Inc's stock which jumped 13 percent to about a five-month high at $12.29 after Bloomberg reported the No. 3 personal computer maker is in talks with private equity firms to go private. Dell's gains offset some tech-sector weakness.

Tech heavyweight Apple lost 3.6 percent to $501.75 and was the biggest weight on both the S&P 500 and Nasdaq 100 <.ndx> indexes after reports the company has cut orders for LCD screens and other parts for the iPhone 5 this quarter due to weak demand. The stock hit a session low of $498.51, the first dip below $500 since February 16.

"With Apple, it seems as if the sentiment has shifted from this being the one stock that everybody wanted to own to people beginning to look at it as a company (whose) business is slowing down somewhat," said Eric Kuby, chief investment officer of North Star Investment Management Corp in Chicago.

Adding to investor unease, fourth-quarter earnings kick into high gear this week. Analyst estimates for the quarter have fallen sharply since October. S&P 500 earnings growth is now seen up just 1.9 percent from a year ago, Thomson Reuters data showed.

The Dow Jones industrial average <.dji> was up 18.89 points, or 0.14 percent, at 13,507.32. The Standard & Poor's 500 Index <.spx> was down 1.37 points, or 0.09 percent, at 1,470.68. The Nasdaq Composite Index <.ixic> was down 8.13 points, or 0.26 percent, at 3,117.50.

Apple suppliers also lost ground, with Cirrus Logic off 9.4 percent at $28.62 and Qualcomm down 1 percent at $64.24.

The Dow fared better than the other two indexes, helped in part by Hewlett-Packard shares, which rose 4.9 percent to $16.95. The stock, up early in the session after JPMorgan upgraded its rating on the shares and raised its price target to $21 from $15, added to gains following the Dell report.

Tech has "become the arena for private equity or other capital-restructuring type of maneuvers because of the way their valuations and their balance sheets are," Kuby said.

Appliance and electronics retailer Hhgregg Inc slumped 5.7 percent to $7.44 after the company cut its same-store sales forecast for the full year.

Earnings reports are due this week from Goldman Sachs , Bank of America , Intel and General Electric , among other companies. Third-quarter reports ended with a gain of just 0.1 percent, the worst for an S&P 500 profit period in three years, according to Thomson Reuters data.

President Barack Obama warned Congress at a news conference on Monday that a refusal to raise the U.S. debt ceiling next month could mean a government shutdown and trigger economic chaos.

S&P futures had little reaction to comments after the bell by Federal Reserve Chairman Ben Bernanke, who urged lawmakers to lift the country's borrowing limit to avoid a debt default.

Volume was roughly 5.6 billion shares traded on the New York Stock Exchange, the Nasdaq and the NYSE MKT, compared with the 2012 average daily closing volume of about 6.45 billion.

Decliners were about even with advancers on the NYSE while decliners outpaced advancers on the Nasdaq by about 12 to 11.

AP source: Lance Armstrong tells Winfrey he doped

AUSTIN, Texas (AP) — Lance Armstrong has finally come clean.

After years of bitter and forceful denials, he offered a simple "I'm sorry" to friends and colleagues and then admitted he used performance-enhancing drugs during an extraordinary cycling career that included seven Tour de France victories.

Armstrong confessed to doping during an interview with Oprah Winfrey taped Monday, just a couple of hours after an emotional apology to the staff at the Livestrong charity he founded and was later forced to surrender, a person familiar with the situation told The Associated Press. The person spoke on condition of anonymity because the interview is to be broadcast Thursday on Winfrey's network.

The confession was a stunning reversal for the proud athlete and celebrity who sought lavish praise in the court of public opinion and used courtrooms to punish his critics.

For more than a decade, Armstrong dared anybody who challenged his version of events to prove it. Finally, he told the tale himself after promising over the weekend to answer Winfrey's questions "directly, honestly and candidly."

Winfrey was scheduled to appear on "CBS This Morning" on Tuesday morning to discuss the interview. She tweeted shortly after the interview: "Just wrapped with (at)lancearmstrong More than 2 1/2 hours. He came READY!"

The cyclist was stripped of his Tour de France titles, lost most of his endorsements and was forced to leave Livestrong last year after the U.S. Anti-Doping Agency issued a damning, 1,000-page report that accused him of masterminding a long-running doping scheme.

Armstrong started the day with a visit to the headquarters of the Livestrong charity he founded in 1997 and turned into a global force on the strength of his athletic dominance and personal story of surviving testicular cancer that had spread to his lungs and brain.

About 100 Livestrong staff members gathered in a conference room as Armstrong told them "I'm sorry." He choked up during a 20-minute talk, expressing regret for the long-running controversy tied to performance-enhancers had caused, but stopped short of admitting he used them.

Before he was done, several members were in tears when he urged them to continue the charity's mission, helping cancer patients and their families.

"Heartfelt and sincere," is how Livestrong spokeswoman Katherine McLane described his speech.

Armstrong later huddled with almost a dozen people before stepping into a room set up at a downtown Austin hotel for the interview with Winfrey. The group included close friends and lawyers. They exchanged handshakes and smiles, but declined comment and no further details about the interview were released because of confidentiality agreements signed by both camps.

Winfrey has promoted her interview, one of the biggest for OWN since she launched the network in 2011, as a "no-holds barred" session, and after the voluminous USADA report — which included testimony from 11 former teammates — she had plenty of material for questions. USADA chief executive Travis Tygart, a longtime critic of Armstrong's, called the drug regimen practiced while Armstrong led the U.S. Postal Service team "the most sophisticated, professionalized and successful doping program that sport has ever seen."

USADA did not respond to requests for comment about Armstrong's confession.

For years, Armstrong went after his critics ruthlessly during his reign as cycling champion. He scolded some in public and didn't hesitate to punish outspoken riders during the race itself. He waged legal battles against still others in court.

At least one of his opponents, the London-based Sunday Times, has already filed a lawsuit to recover about $500,000 it paid him to settle a libel case, and Dallas-based SCA Promotions, which tried to deny Armstrong a promised bonus for a Tour de France win, has threatened to bring another lawsuit seeking to recover more than $7.5 million awarded by an arbitration panel.

Betsy Andreu, the wife of former Armstrong teammate Frankie Andreu, was one of the first to publicly accuse Armstrong of using performance-enhancing drugs. She called news of Armstrong's confession "very emotional and very sad," and choked up when asked to comment.

"He used to be one of my husband's best friends and because he wouldn't go along with the doping, he got kicked to the side," she said. "Lance could have a positive impact if he tells the truth on everything. He's got to be completely honest."

Betsy Andreu testified in SCA's arbitration case challenging the bonus in 2005, saying Armstrong admitted in an Indiana hospital room in 1996 that he had taken many performance-enhancing drugs, a claim Armstrong vehemently denied.

"It would be nice if he would come out and say the hospital room happened," Andreu said. "That's where it all started."

Former teammate Floyd Landis, who was stripped of the 2006 Tour de France title for doping, has filed a federal whistle-blower lawsuit that accused Armstrong of defrauding the U.S. Postal Service. An attorney familiar with Armstrong's legal problems told the AP that the Justice Department is highly likely to join the lawsuit. The False Claims Act lawsuit could result in Armstrong paying a substantial amount of money to the U.S. government. The deadline for the department to join the case is Thursday, though the department could seek an extension if necessary.

According to the attorney, who works outside the government, the lawsuit alleges that Armstrong defrauded the U.S. government based on his years of denying use of performance-enhancing drugs. The attorney spoke on condition of anonymity because the source was not authorized to speak on the record about the matter.

The lawsuit most likely to be influenced by a confession might be the Sunday Times case. Potential perjury charges stemming from Armstrong's sworn testimony in the 2005 arbitration fight would not apply because of the statute of limitations. Armstrong was not deposed during the federal investigation that was closed last year.

Armstrong is said to be worth around $100 million. But most sponsors dropped him after USADA's scathing report — at the cost of tens of millions of dollars — and soon after, he left the board of Livestrong.

After the USADA findings, he was also barred from competing in the elite triathlon or running events he participated in after his cycling career. World Anti-Doping Code rules state his lifetime ban cannot be reduced to less than eight years. WADA and U.S. Anti-Doping officials could agree to reduce the ban further depending on what information Armstrong provides and his level of cooperation.

Ohio gas prices tick up amid recovery hopes

COLUMBUS, Ohio (AP) — Ohio gas prices are higher to start the new work week.

The average price for a gallon of regular gas in Ohio was $ 3.24 in Monday’s survey from auto club AAA, the Oil Price Information Service and Wright Express. That’s 5 cents higher than a week ago.

Ohio’s prices are still below the national average of $ 3.30, which is about the same as last week.

The lowest average price in Ohio Monday was $ 3.16 in the Toledo area.

Experts say China and the U.S. appear to be on a solid track of economic recovery, which supports oil prices at higher levels. Prices are also rising because of increased energy consumption in China, which is enduring its coldest winter in nearly three decades.

Are gun curbs just symbolism?

STORY HIGHLIGHTS

• Gun violence recommendations are expected from Vice President Biden on Tuesday


• The proposals are expected to contain substantive and symbolic ideas to curb gun violence


• Presidents use symbolism to shift public opinion or affect larger political or social change

Washington (CNN) -- The pictures told the story: Vice President Joe Biden looked solemn, patrician and in control as he sat at a long table in the White House, flanked by people on both sides of the gun control issue.

The images conveyed a sense that the White House was in command on this issue.

And that's the point. Historically, presidential administrations have used symbolic imagery—at times coupled with marginal actions—to shift public opinion or affect larger political or social change.

"Politics is a risk taking project," said Julian Zelizer, a Princeton University historian and CNN contributor. "They put together these commissions in response to some crisis. You try a hundred things and hope something works."

On the eve of the Biden-led gun control task force recommendations to President Barack Obama, political experts say it is important that his administration sends a clear signal that it has things in hand.

That is especially critical in what will likely be an uphill battle to push specific changes, like an assault weapons ban, as part of a broader effort on gun control.

The first move in the image battle will be to appear to move quickly and decisively.

"You have to give the Obama administration credit for one thing: They've learned from history to do things quickly," Larry Sabato, director of the University of Virginia's Center for Politics, said of previous task force initiatives that fizzled.

In 2010, Obama appointed a bipartisan commission headed by former Republican Sen. Alan Simpson of Wyoming and Erskine Bowles, a former Democratic White House chief of staff, to come up with a proposal to balance the budget and cut the debt.

Like the gun task force, Simpson-Bowles reviewed current regulations, gathered input from the public and engaged in tense internal conversations. But after months of working on a proposal—a blend of steep revenue increases and spending cuts—the group struggled to agree to a solution. The president did not take up the recommendations.

Obama largely avoided the issue of gun control during his first term.

He wrote an opinion piece two months after the 2011 assassination attempt on Rep. Gabrielle Giffords of Arizona, acknowledging the importance of the Second Amendment right to bear arms. In the piece he also called for a focus on "effective steps that will actually keep those irresponsible, law-breaking few from getting their hands on a gun in the first place."

But in the aftermath of that shooting and as the election season loomed, the Justice Department backed off from a list of recommendations that included a measure designed to help keep mentally ill people from getting guns.

For now, at least, there is a sense in Washington that the Newtown, Connecticut, school shooting where 26 people -- 20 of them young children -- were slaughtered could lead to meaningful legislative reform.

Public opinion would seem to suggest that the White House efforts are well timed.

In the month since the massacre, a new poll showed the percentage of Americans who said they were dissatisfied with America's gun laws has spiked.

The Gallup survey released on Monday showed 38% of Americans were dissatisfied with current gun regulations, and wanted stricter laws. That represented 13-point jump from one year ago, when 25% expressed that view. "You want to strike while the iron is hot," Sabato said. "We Americans have short attention spans and, as horrible as the Newtown shooting was, will anyone be surprised if we moved along by spring?"

The White House has since worked overtime to show it considers gun control an urgent matter.

The vice president has spent the last week meeting with what the White House calls "stakeholders" in the gun control debate.

On Monday, Biden was to meet with members of a House Democratic task force on guns, along with Attorney General Eric Holder, Homeland Security Secretary Janet Napolitano, and Kathleen Sebelius, the secretary of Health and Human Services.

In a series of face to face discussions on Thursday, Biden sat down with the National Rifle Association and other gun owners groups before conferring with representatives from the film and television industry.

In a sign the White House is prepared to move aggressively on its proposals, Biden made public comments just before meeting with the National Rifle Association, the country's most powerful gun lobby.

"Putting the vice president in charge of (the task force) and having him meeting with these groups is intended to show seriousness and an effort to reach out and respond to concerns and wishes of various groups," said Alan Abramowitz, a political science professor at Emory University.

Still, the NRA expressed disappointment in its discussion with Biden and later released a statement that accused the administration of mounting "an agenda to attack the Second Amendment."

Organizations seeking tougher gun control laws insist an assault weapons ban is critical to addressing the nation's recent rash of mass shootings. However, such a ban could be difficult in a Congress mired in gridlock.

"The bully pulpit is limited. It's hard for the president to sustain that momentum," Zelizer said of the White House's gun control efforts after the Newtown shootings. "The thing about symbolism is, like the shock over Newtown, they fade quickly."

City prepared to pay $33 million in two cop misconduct cases

Chicago Tribune reporter David Heinzmann on news that Mayor Rahm Emanuel seeks to settle two notorious cases of alleged police misconduct. (Posted Jan. 14th, 2013)

Nearly seven years after Christina Eilman wandered out of a South Side police station and into a catastrophe, her tragic entanglement with the Chicago Police Department began to come to an end Monday — with a proposed $22.5 million legal settlement that may be the largest the city ever offered to a single victim of police misconduct.

Though the settlement is a staggering sum on its own, Mayor Rahm Emanuel's administration has placed a second eight-figure police settlement on Tuesday's City Council Finance Committee agenda. A $10.2 million settlement is proposed for one of the victims of notorious former police Cmdr. Jon Burge, bringing to nearly $33 million the amount aldermen could vote to pay victims of police misconduct in a single day.

The latest Burge settlement would be for Alton Logan, who spent 26 years in prison for a murder he did not commit and who alleged in a federal lawsuit that Burge's team of detectives covered up evidence that would have exonerated him — a departure from previous cases that documented torture used by Burge's team to extract false confessions. The Logan case would bring the tab on Burge cases to nearly $60 million when legal fees are counted. Burge is serving 41/2 years in federal prison for lying about the torture and abuse of suspects.

The settlement in the Eilman case would avert a trial detailing the events of May 2006, when the then-21-year-old California woman was arrested at Midway Airport in the midst of a bipolar breakdown. She was held overnight and then released at sundown the next day without assistance several miles away in one of the city's highest-crime neighborhoods.

Alone and bewildered by her surroundings, the former UCLA student was abducted and sexually assaulted before plummeting from a seventh-floor window. She survived but suffered a severe and permanent brain injury, a shattered pelvis, and numerous other broken bones and injuries.

Her lawyer and family declined to comment Monday. The case, which has dragged in the courts for six years, was set to begin trial next week. Pretrial litigation had produced scathing rebukes from federal judges of the city's behavior toward Eilman — both on the street and in court.

The city's argument that it was not responsible for her injuries because she was assaulted by a gang member was blasted in a ruling from the 7th U.S. Circuit Court of Appeals this year. a ruling from the 7th U.S. Circuit Court of Appeals this year. Chief Judge Frank Easterbrook described the Police Department's release of Eilman, who is white, into a high-crime, predominantly African-American neighborhood by saying officers "might as well have released her into the lion's den at the Brookfield Zoo."

While Emanuel's Law Department endured some criticism for delays in the Eilman case since the mayor took office in 2011, he has noted repeatedly that the police misconduct highlighted in these and many other cases are legacies from the Richard M. Daley administration that he — and taxpayers — are stuck with.

The mayor's office referred calls to the city Law Department, but a spokesman there declined to comment.

If approved, the Eilman settlement would surpass the $18 million settlement paid to the family of LaTanya Haggerty, who was mistakenly shot and killed by police in 1999. It is frequently referred to as the city's biggest single-victim settlement.

Ald. Howard Brookins Jr., 21st, said city officials have not taken a hard enough line against police misconduct for years, and now taxpayers are footing the bill.

"We've known this was going to bust our budget, and here we are," Brookins said. "The administration (under Daley) should have made police conduct and behavior a higher priority. They didn't, and now we're seeing these costly settlements over and over, to pay for officers mistreating people."

The Logan case was set to go to trial last month, but on the first day of jury selection, city lawyers decided to settle the case. Logan's attorney Jon Loevy said the settlement includes about $1.5 million in legal fees.

Logan sat in prison for 26 years until a stunning 2008 revelation after another man, convicted murderer Andrew Wilson, died. Wilson had told his attorneys in 1982 that he committed the murder in which Logan was accused, but the lawyers said the attorney-client privilege kept them from going public with the admission until after Wilson's death.

Although relieved the city settled the case instead of battling on, Loevy said his client would gladly give up the $8.7 million to have nearly three decades of his life back.

"I don't know who would take that much money to lose their 20s, 30s and 40s," Loevy said. "From his perspective, no amount of money can make him whole and he'd rather have his life back."

While Logan lost the middle chunk of his life, Eilman dwells in a childlike mental state and feels as though she has lost the rest of her life, her family has told the Tribune.

Hobbled by a brain injury that has permanently impaired her cognitive function, she lives with her parents in suburban Sacramento. She requires constant medical treatment and therapy. Doctors have said she will not get better.

Eilman came to Chicago on May 5, 2006, at a time when her bipolar condition was worsening. When she tried to catch a return flight from Midway to California a couple of days later, she was ranting and screaming and appeared to be out of her mind.

Police officers eventually arrested her and took her to the Chicago Lawn district near Midway. Court records and depositions in the case show that officers were alarmed by Eilman's behavior.

France keeps up Mali air strikes, African troop plan advances

BAMAKO (Reuters) - France kept up its air strikes against Islamist rebels in Mali as plans to deploy African troops gathered pace on Tuesday amid concerns that delays could endanger a wider mission to dislodge al Qaeda and its allies.

France has already poured hundreds of troops into Mali and carried out days of air strikes since Friday in a vast desert area seized last year by an Islamist alliance that combines al Qaeda's north African wing AQIM with Mali's home-grown MUJWA and Ansar Dine rebel groups.

Western and regional powers are concerned the insurgents will use Mali's north as a launchpad for international attacks.

West African defense chiefs were to meet in Bamako on Tuesday to approve plans to speed up the deployment of 3,300 regional troops foreseen in a U.N.-backed intervention plan to be led by Africans.

Speaking from a French military base in Abu Dhabi at the start of a day-long visit to the United Arab Emirates, President Francois Hollande said French forces in Mali had carried out further strikes overnight "which hit their targets."

"We will continue the deployment of forces on the ground and in the air," Hollande said. "We have 750 troops deployed at the moment and that will keep increasing so that as quickly as possible we can hand over to the Africans."

He saw the African troop deployment taking "a good week".

France plans to field a total 2,500 soldiers in its former colony to bolster the Malian army and work with the intervention force provided by the ECOWAS grouping of West African states.

Foreign Minister Laurent Fabius - accompanying Hollande on a visit aimed at firming up trade relations and making progress on a possible sale of 60 French Rafale fighter jets - said he was confident Gulf Arab states would also help the Mali campaign.

Fabius said there would be a meeting of donors for the Mali operation most likely in Addis Ababa at the end of January.

He predicted the current level of the French involvement in Mali would go on for "a matter of weeks".

ECOWAS mission head in Bamako Aboudou Toure Cheaka said the West African troops would be on the ground in a week. Their immediate mission would be to help stop the rebel advance while preparations for a full intervention plan continued.

The original timetable for the 3,300-strong U.N.-sanctioned African force - backed by western logistics, money and intelligence services - did not initially foresee full deployment before September due to logistical constraints.

Senegal, Burkina Faso, Niger, Nigeria and Guinea have all offered troops. But regional powerhouse Nigeria, which is due to lead the mission, has cautioned that even if some troops arrive in Mali soon, training will take more time.

The plan is being fast-tracked after a plea for help by Mali's government after mobile columns of Islamist fighters last week threatened the central garrison towns of Mopti and Sevare, with its key airport.

"SAFEGUARD MALI"

French Prime Minister Jean-Marc Ayrault said France's goals were to stop the Islamist rebels, to "safeguard the existence of Mali" and pave the way for the African-led military operation.

U.S. officials said Washington was sharing information with French forces in Mali and considering providing logistics, surveillance and airlift capability.

"We have made a commitment that al Qaeda is not going to find anyplace to hide," U.S. Defense Secretary Leon Panetta told reporters as he began a visit to Europe.

As French aircraft bombarded mobile columns of Islamist fighters, other insurgents launched a counter-attack further to the south, dislodging government forces from the town of Diabaly, 350 km (220 miles) from Bamako.

French intervention has raised the risk for eight French hostages held by al Qaeda allies in the Sahara and for 30,000 French expatriates living in neighboring, mostly Muslim states. Concerned about reprisals at home, France has tightened security at public buildings and on public transport.

The U.N. said an estimated 30,000 people had fled the latest fighting in Mali, joining more than 200,000 already displaced.

U.N. Secretary-General Ban Ki-moon on Monday welcomed the French-led military intervention in Mali and voiced the hope that it would halt the Islamist assault.

Amnesty International said at least six civilians were killed in recent fighting in the town of Konna, where French aircraft had earlier bombarded rebel positions, and called on both sides to spare non-combatants.

France, which has repeatedly said it has abandoned its role as the policeman of its former African colonies, is among the toughest proponents of a speedier deployment of the African troops, and convened a U.N. Security Council meeting Monday to discuss the crisis.

French U.N. Ambassador Gerard Araud told reporters after the meeting that the U.S., Canada, Belgium, Denmark and Germany had also offered logistical support for France's Mali operation.

"I felt that all the members of the Security Council were expressing their support (for) and understanding of the French decision," Araud told reporters.

No Europeans or other African Union members will be allowed in the defense chiefs meeting in Bamako on Tuesday, a western diplomat told Reuters, requesting not to be named.

"They don't want any French pressure at the meeting," the diplomat said.
