Turn up the bass to scare birds away from planes

PLANES and birds aren't good at sharing air space - bird strikes worldwide cause over a billion dollars in damage every year, and put passengers and crew at risk. To scare avians away, a new device will fire low-frequency sound waves at flocks as they near busy flight paths.

Noise makers are often used to scare birds away from airports or contaminated waterways. But loud sounds also annoy any humans within earshot.

Now a system developed by Technology International, based in Laplace, Louisiana, aims to deter birds using infrasound, below the range of human hearing.

The trial version of the Avian Infrasound Non-lethal Denial System has a passive infrasound detector that listens for an approaching flock, and activates a series of rotary subwoofers that generate high-intensity, but low-frequency sound. It worked well in tests.

Thunderstorms also emit lots of infrasound, which may be why birds are naturally averse to it, says Abdo Husseiny, the firm's CEO.

Husseiny adds that the system could be used to keep pigeons away from public squares, or divert flocks away from wind turbines. He says that the equipment should be commercially available within two years.

Football: Clubs may be demoted over racism: Blatter

SAINT-PETERSBURG, Russia: FIFA president Sepp Blatter said in St Petersburg on Sunday that clubs where racist incidents occurred could face punishments of anything from points deduction or even demotion.

The 76-year-old Swiss added that without heavy punishment racism would remain within the sport.

"The entire world fights against racism and discrimination," Blatter told a press conference.

"Football is part of the world's society. We unite more than 300 million people around the world and should set an example. Without serious sanctions nothing will ever change."

Blatter's remarks come in the light of Ghanaian midfielder Kevin-Prince Boateng leading his AC Milan team-mates off the pitch in a club friendly earlier this month after being racially abused.

While Blatter had criticised Boateng's actions saying it was the wrong solution, he added that there was zero tolerance for racist abuse.

Blatter also announced on Sunday that he did not agree with the idea of re-establishing the post-Soviet football league by grouping together the best teams of the former USSR.

The ambitious plan was mooted last month by Alexei Miller, the chief of Gazprom, owner and main sponsor of Russian champions Zenit St Petersburg, and has picked up support from many top clubs of the former Soviet Republics.

"The creation of the CIS league goes against FIFA principles," the world football supremo told a news conference.

"The head of Russia's football Union (RFU) Nikolai Tolstykh should continue holding the country's championships and forget about the project of revival of the Soviet-type CIS (Commonwealth of Independent States) league."

Blatter added that FIFA has a clear structure of tournaments, where club competitions were held within the national federations or continental associations like UEFA's Champions League or the Libertadores Cup.

"The new league can break the existing FIFA structure and bring disarray into it," Blatter said. "FIFA will never give its approval to such a project. Russian football officials should forget about this idea."

Tolstykh expressed his support by saying: "The RFU has a clear position - football life in the country should be subordinate to FIFA, UEFA and RFU regulations."

Stan 'The Man' Musial dies

Photo portrait of Stan Musial in the 1960s.

STORY HIGHLIGHTS

• Musial played 22 years in the Major League, all with the St. Louis Cardinals


• He retired in 1963 as, statistically, one of the best hitters in baseball history


• He died Saturday evening of natural causes, his grandson says


• Baseball commissioner, players, fans recall Musial as a great athlete and man

(CNN) -- He was simply "The Man."

Stanley Frank Musial made a name for himself as one of baseball's best hitters of all time on the field, as well as one of its greatest, most dignified ambassadors off it.

And now "Stan the Man" is gone. Musial died at his Ladue, Missouri, home surrounded by family, the Cardinals said in a statement. According to a post on his Twitter page, which is maintained by his grandson Brian Musial Schwarze, Musial died at 5:45 p.m. (6:45 p.m. ET) Saturday of natural causes.

He was 92.

"We have lost the most beloved member of the Cardinals family," said William DeWitt Jr., the club's chairman. "Stan Musial was the greatest player in Cardinals history and one of the best players in the history of baseball."

The Pennsylvania-born Musial transitioned from a lackluster pitcher to a stellar slugging outfielder, according to his biography on the National Baseball Hall of Fame's website.

The left-hander had a batting average above .300 17 times during his 22-year career -- all played with St. Louis -- and earned three National League Most Valuable Player awards as well as three World Series titles. The only blip came in 1945, in the thick of World War II, when he left baseball to join the U.S. Navy.

Stan Musial waves to fans during the 2012 National League Championship Series.

After the 1963 season, Musial retired with a .331 career batting average and as the National League's career leader in RBI, games played, runs scored, hits and doubles. He has since been surpassed in some of those categories, but he still ranks fourth in baseball history in total hits, behind only Pete Rose, Ty Cobb and Hank Aaron.

Hall of Fame manager Earl Weaver dead

He also stood out for his grace and sportsmanship -- having never been ejected once by an umpire. In his retirement ceremony, then-Major League Commissioner Ford Frick referred to Musial as "baseball's perfect warrior, baseball's perfect knight."

In 1969, Musial was elected on his first try into the Hall of Fame, calling it "the greatest honor of the many that have been bestowed upon me."

During and after his playing career, Musial developed a special relationship with the St. Louis fan base, who knew him simply as "Stan the Man."

A bronze statue of him stands outside Busch Stadium, which is located in Musial Plaza along Stan Musial Drive.

He continued with the organization for more than 25 years after his playing days ended, serving as vice president and general manager.

And Musial was active in the community, contributing to causes such as the USO, the Senior Olympics, the Boy Scouts and Covenant House.

People we lost in 2013

HIDE CAPTION

"I have no hesitation to say that St. Louis is a great place in which to live and work," he said in his Hall of Fame induction speech. "We love St. Louis."

His fans returned the favor, revering him for his play as well as his character and commitment to the area.

"Cardinal Nation will never be the same. Rest in peace Stan 'The Man' Musial, the best Cardinal there ever was," wrote one woman, by the name of Elise, on Twitter.

Musial also stood tall outside eastern Missouri. He served between 1964 and 1967 as chairman of the President's Council on Physical Fitness and Sports.

In 2011, President Barack Obama bestowed upon him the Presidential Medal of Freedom, the nation's highest civilian honor.

"Stan matched his hustle with humility," Obama said then. "Stan remains, to this day, an icon, untarnished; a beloved pillar of the community; a gentleman you'd want your kids to emulate."

Lillian, Musial's wife of 71 years, died last May -- a longlasting marriage that some people, online, called as admirable as anything that happened on the diamond.

Stan Musial's passing spurred an outpouring of condolences and praise. Commissioner Bud Selig described him as "a Hall of Famer in every sense" and "a true gentleman," former pitcher Curt Schilling called his life "a clinic in respect, integrity and honor," and current Cardinal Matt Holliday said it was "an honor to the same uniform."

The messages from fans were no less heartfelt.

Wrote Jason Lukehart, on Twitter: "In a week that's shown the dangers deifying athletes, Stan Musial's death reminds me that once in a great while, there's a man worthy of it."

Algeria Hostage Crisis Over, One American Dead

After the Algerian military's final assault on terrorists holding hostages at a gas complex, the four-day hostage crisis is over, but apparently with additional loss of life among the foreign hostages.

One American, Fred Buttaccio of Texas, has been confirmed dead by the U.S. State Department. Two more U.S. hostages remain unaccounted for, with growing concern among U.S. officials that they did not survive.

But another American, Mark Cobb of Corpus Christi, Texas is now confirmed as safe. Sources close to his family say Cobb, who is a senior manager of the facility, is safe and reportedly sent a text message " I'm alive."

In a statement, President Obama said, "Today, the thoughts and prayers of the American people are with the families of all those who were killed and injured in the terrorist attack in Algeria. The blame for this tragedy rests with the terrorists who carried it out, and the United States condemns their actions in the strongest possible terms. ... This attack is another reminder of the threat posed by al Qaeda and other violent extremist groups in North Africa."

According to Algerian state media, 32 militants are dead and a total of 23 hostages perished during the four-day siege of the In Amenas facility in the Sahara. The Algerian Interior Ministry also says 107 foreign nationals who worked at the facility for BP and other firms were rescued or escaped from the al Qaeda-linked terrorists who took over the BP joint venture facility on Wednesday.

The Japanese government says it fears "very grave" news, with multiple casualties among the 10 Japanese citizens working at the In Amenas gas plant.

Five British nationals and one U.K. resident are either deceased or unaccounted for in the country, according to British Foreign Minister William Hague. Hague also said that the Algerians have reported that they are still trying to clear boobytraps from the site.

Blinded by sun? Let your steering wheel guide you

WORRIED that the sun in your eyes will impair your driving? For the first time, a vibrating steering wheel will tell drivers where to steer when undipped headlights or other visual impediments leave them temporarily blinded.

Eelke Folmer and Burkay Sucu at the University of Reno in Nevada, designed the steering wheel to help cut the accident toll caused by glare, especially in winter, when motorists are most likely to be dazzled by low sun and reflections from snow and ice.

Cars with vibrating seats can already warn drivers when another vehicle is approaching in their blind spot. But the team's design is the only one to help drivers steer using tactile cues. The system relies on car sensors like GPS and lane-keeping cameras to map the road ahead and work out where the vehicle is. When sensors detect the driver may be dazzled and drifting from their lane, the vibro-tactile system buzzes into action.

The vibrations are tuned to 275 hertz, the frequency that our skin is most sensitive to. And the cues are directional, so if a driver drifts left, the left side of the wheel will vibrate - a signal to steer right until it stops vibrating, just like a rumble strip. "It's fairly easy for the system to anticipate or sense glare conditions and activate itself," says Folmer. The system worked well in tests with 12 volunteers in a simulator, but the drivers' hands strayed from the left and right vibrators - so the devices may need to be more widely distributed around the wheel.

It's promising work, says Paul Newman, who is developing a driverless car at the University of Oxford. "Touch is an extraordinarily rich sensory pathway and is an ideal way to provide safety-improving hints. In this case, the hints are felt at the very place action is required - on the steering wheel itself," he says.

Migrant Workers' Centre urges flexibility in Change of Employer policy

SINGAPORE: The Migrant Workers' Centre has urged the government to be more flexible in allowing foreign workers to change employers.

The centre's Chairman Yeo Guat Kwang told Channel NewsAsia that he is working with the Manpower Ministry to try and amend the policy.

The Migrant Workers' Centre said last year it received about 1,500 complaints from foreign workers, mostly for salary arrears cases.

Workers helping the Manpower Ministry with investigations are given a special pass to stay in Singapore under the Temporary Job Scheme.

Under the scheme, workers serving as prosecution witnesses may be allowed to find temporary employment while their cases are being investigated.

Migrant workers groups want the Temporary Job Scheme to be expanded to allow workers to remain in Singapore beyond the completion of their cases.

Mr Yeo said workers who are waiting for their workplace injury compensation should also be allowed to stay.

This, he said, could lead the way for a new transitional employment system for foreign workers.

Mr Yeo said: "If you say the only way for the workers is to go back, for some cases, it's not fair because they've only been here for a few months. I think we should amend this to make it easier for workers who unfortunately fall victim to one of these disputes, will be able to find employment with another employer.

"To me, I think it's good for the employer to employ these workers who are already here, rather than to go to the source country, and do a fresh recruitment, and these are workers who have already been here, we know how good their skills are."

Mr Yeo explained that making the Change of Employers policy more flexible is also in line with the MWC's call to improve the quality of foreign workers.

"At the end of the day, for us to be able to enable them to change employer and get re-employed, definitely this is a person that must have the right skill to work here," said Mr Yeo.

In addition, the Humanitarian Organisation for Migration Economics believes the restrictions of the Change of Employer policy do not favour these workers.

The organisation's president Bridget Tan explained: "This is called the sponsorship system. A work permit holder is tied to the employer. The work permit holder if once he or she leaves the employer unless with the approval of the employer this work permit holder will have to go home, repatriated.

"They find it difficult to enforce their rights under work permit conditions because they are so afraid and often threatened. Going home for many migrant workers whether domestic workers or foreign workers is not a choice for them because most of them are in debt to agents back home, money lenders back home.

"And going back with nothing, with no hope and promise of another job and the chance to change employers, sometimes they allow themselves to be exploited."

Ms Tan added workers are not allowed to change the industry they work in.

She said: "For example, if you come in as a construction worker, you can only find a job as a construction worker even though you have qualification that can allow you to work for example, as a waiter but you cannot because you come in as a construction worker, you have to be a construction worker. There are restrictions."

President of the Association of Employment Agencies, K Jayaprema said employers have concerns with a more flexible policy.

Mr Jayaprema said: "When such transfers kick in, if the employees are not very responsible, the employer might be stranded without a workforce because employees do have a tendency to be working in one company, train themselves up there and when there's opportunities in another company with a little bit of better salary, they move."

Employers have to send their foreign workers back within seven days of the cancellation of their work permits or they could lose the S$5,000 security bond with the Manpower Ministry.

Advocacy groups for migrant workers argue a more flexible change of employer policy would create greater mobility for workers.

With this mobility, migrant workers will no longer be at the mercy of employers.

There will be more incentive for employers to retain these workers, and treat them fairly.

MPs are expected to raise questions on how the government can address the grievances of foreign workers at the next sitting of Parliament.

Will Obama's new methods be better?

President Obama announces his administration's new gun law proposals Wednesday.

STORY HIGHLIGHTS

• David Gergen: Since re-election, Obama seems smarter, tougher, bolder


• He says president outmanuevered opponents on taxes, key appointments


• Did Obama miss an opportunity to work cooperatively with GOP, Gergen asks


• Gergen: Conservatives fear Obama is trying to run over them

Editor's note: David Gergen is a senior political analyst for CNN and has been an adviser to four presidents. A graduate of Harvard Law School, he is a professor of public service and director of the Center for Public Leadership at Harvard University's Kennedy School of Government. Follow him on Twitter. Watch CNN's comprehensive coverage of President Barack Obama's second inauguration this weekend on CNN TV and follow online at CNN.com or via CNN's apps for iPhone, iPad and Android.

(CNN) -- On the eve of his second inaugural, President Obama appears smarter, tougher and bolder than ever before. But whether he is also wiser remains a key question for his new term.

It is clear that he is consciously changing his leadership style heading into the next four years. Weeks before the November elections, his top advisers were signaling that he intended to be a different kind of president in his second term.

David Gergen

"Just watch," they said to me, in effect, "he will win re-election decisively and then he will throw down the gauntlet to the Republicans, insisting they raise taxes on the wealthy. Right on the edge of the fiscal cliff, he thinks Republicans will cave."

What's your Plan B, I asked. "We don't need a Plan B," they answered. "After the president hangs tough -- no more Mr. Nice Guy -- the other side will buckle." Sure enough, Republicans caved on taxes. Encouraged, Obama has since made clear he won't compromise with Republicans on the debt ceiling, either.

Obama 2.0 stepped up this past week on yet another issue: gun control. No president in two decades has been as forceful or sweeping in challenging the nation's gun culture. Once again, he portrayed the right as the enemy of progress and showed no interest in negotiating a package up front.

In his coming State of the Union address, and perhaps in his inaugural, the president will begin a hard push for a comprehensive reform of our tattered immigration system. Leading GOP leaders on the issue -- Sen. Marco Rubio, R-Florida, for example -- would prefer a piecemeal approach that is bipartisan. Obama wants to go for broke in a single package, and on a central issue -- providing a clear path to citizenship for undocumented residents -- he is uncompromising.

After losing out on getting Susan Rice as his next secretary of state, Obama has also shown a tougher side on personnel appointments. Rice went down after Democratic as well as Republican senators indicated a preference for Sen. John Kerry. But when Republicans also tried to kill the nomination of Chuck Hagel for secretary of defense, Obama was unyielding -- an "in-your-face appointment," Sen. Lindsay Graham, R-South Carolina, called it, echoing sentiments held by some of his colleagues.

Will Obama's second inauguration let America turn the page?

Republicans would have preferred someone other than Jack Lew at Treasury, but Obama brushed them off. Hagel and Lew -- both substantial men -- will be confirmed, absent an unexpected bombshell, and Obama will rack up two more victories over Republicans.

His new style is paying off politically. But in the long run, will it also pay off in better governance?
David Gergen

Strikingly, Obama has also been deft in the ways he has drawn upon Vice President Joe Biden. During much of the campaign, Biden appeared to be kept under wraps. But in the transition, he has been invaluable to Obama in negotiating a deal with Senate Minority Leader Mitch McConnell on the fiscal cliff and in pulling together the gun package. Biden was also at his most eloquent at the ceremony announcing the gun measures.

All of this has added up for Obama to one of the most effective transitions in modern times. And it is paying rich dividends: A CNN poll this past week pegged his approval rating at 55%, far above the doldrums he was in for much of the past two years. Many of his long-time supporters are rallying behind him. As the first Democrat since Franklin D. Roosevelt to score back-to-back election victories with more than 50% of the vote, Obama is in the strongest position since early in his first year.

Smarter, tougher, bolder -- his new style is paying off politically. But in the long run, will it also pay off in better governance? Perhaps -- and for the country's sake, let's hope so. Yet, there are ample reasons to wonder, and worry.

Avlon: GOP's surprising edge on diversity

Ultimately, to resolve major issues like deficits, immigration, guns and energy, the president and Congress need to find ways to work together much better than they did in the first term. Over the past two years, Republicans were clearly more recalcitrant than Democrats, practically declaring war on Obama, and the White House has been right to adopt a tougher approach after the elections.

But a growing number of Republicans concluded after they had their heads handed to them in November that they had to move away from extremism toward a more center-right position, more open to working out compromises with Obama. It's not that they suddenly wanted Obama to succeed; they didn't want their party to fail.

House Speaker John Boehner led the way, offering the day after the election to raise taxes on the wealthy and giving up two decades of GOP orthodoxy. In a similar spirit, Rubio has been developing a mainstream plan on immigration, moving away from a ruinous GOP stance.

One senses that the hope, small as it was, to take a brief timeout on hyperpartisanship in order to tackle the big issues is now slipping away.

Zelizer: Second-term Obama will play defense

While a majority of Americans now approve of Obama's job performance, conservatives increasingly believe that in his new toughness, he is going overboard, trying to run over them. They don't see a president who wants to roll up his sleeves and negotiate; they see a president who wants to barnstorm the country to beat them up. News that Obama is converting his campaign apparatus into a nonprofit to support his second term will only deepen that sense. And it frustrates them that he is winning: At their retreat, House Republicans learned that their disapproval has risen to 64%.

Conceivably, Obama's tactics could pressure Republicans into capitulation on several fronts. More likely, they will be spoiling for more fights. Chances for a "grand bargain" appear to be hanging by a thread.

Two suspicions are starting to float among those with distaste for the president. The first is that he isn't really all that committed to bringing deficits under control. If he were, he would be pushing a master plan by now. Instead, it is argued, he will tinker with the deficits but cares much more about leaving a progressive legacy -- health care reform, a stronger safety net, green energy, and the like.

Second, the suspicion is taking hold that he is approaching the second term with a clear eye on elections ahead. What if he can drive Republicans out of control of the House in 2014? Then he could get his real agenda done. What if he could set the stage for another Democrat to win the presidency in 2016? Then he could leave behind a majority coalition that could run the country for years, just as FDR did. Democrats, of course, think the real point is that Obama is finally showing the toughness that is needed.

We are surely seeing a new Obama emerge on the eve of his second term. Where he will now lead the country is the central question that his inaugural address and the weeks ahead will begin to answer.

T'eo to hoax doubters: "I wasn't part of this"

Updated 12:15 AM ET

SOUTH BEND, Ind. Manti Te'o gave an interview to ESPN in which he denied any involvement in fabricating an online relationship with a woman he considered to be his girlfriend.

"I wasn't faking it," he told ESPN Friday night. "I wasn't part of this."

Te'o also said that he did not make up anything to help his Heisman Trophy candidacy.

"When (people) hear the facts, they'll know," he said. "They'll know that there is no way that I could be part of this."

Te'o spoke at the IMG Training Academy in Bradenton, Fla., where he is preparing for the NFL draft. There were no cameras at the 2?-hour interview, which was recorded.

Earlier, Notre Dame athletic director Jack Swarbrick said during the taping of his weekly radio show that Te'o has to explain exactly how he was duped into an online relationship with a fictitious woman whose "death" was then faked by perpetrators of the scheme.

Skeptics have questioned the versions of events laid out by Te'o and Notre Dame, wondering why Te'o never said his relationship was with someone online and why he waited almost three weeks to tell the school about being duped.

Will scandal affect Manti Te'o's NFL future?

According to Notre Dame, Te'o received a call on Dec. 6 from the girl he had only been in contact with by telephone and online, and who he thought had died in September. After telling his family what happened while he was home in Hawaii for Christmas, he informed Notre Dame coaches on Dec. 26.

Notre Dame said it hired investigators to look into Te'o's claims and their findings showed he was the victim of an elaborate hoax.

Notre Dame rallies to Manti Te'o's side

Te'o released a statement on Wednesday, soon after Deadspin.com broke news of the scam with a lengthy story, saying he had been humiliated and hurt by the "sick joke." But he has laid low since.

ESPN officials posted a photo on Twitter late Friday night of reporter Jeremy Schapp with Te'o and his attorney. Te'o has been working out at the IMG Academy in Bradenton, Fla., as he prepares for the NFL combine and draft.

Notre Dame athletic director: Faith in Te'o hasn't shaken "one iota"

Swarbrick said earlier in the day that he believed Te'o would ultimately speak publicly.

"We are certainly encouraging it to happen," he said. "We think it's important and we'd like to see it happen sooner rather than later."

He said thatmant before the Deadspin story, Te'o and his family had planned to go public with the story Monday.

"Sometimes the best laid plans don't quite work, and this was an example of that. Because the family lost the opportunity in some ways to control the story," he said. "It is in the Te'o family's court. We are very much encouraging them."

Former NFL coach Tony Dungy, who mentored Michael Vick when he returned to the NFL after doing prison time, had similar advice.

"I don't know the whole case but I always advise people to face up to it and just talk to people and say what happened," Dungy said while attending the NCAA convention in Dallas on Friday. "The truth is the best liberator, so that's what I would do. And he's going to get questioned a lot about it."

Te'o led a lightly regarded Fighting Irish team to a 12-0 regular season and the BCS title game, where they were routed 42-14 by Alabama and Te'o played poorly.

Dungy said Te'o could face the toughest questions from NFL teams.

"If I was still coaching and we're thinking about taking this guy in the first round, you want to know not exactly what happened but what is going on with this young man and is it going to be a deterrent to him surviving in the NFL and is it going to stop him from being a star," Dungy said. "So just tell the truth about what happened and this is why, I think, that's the best thing."

Deadspin reported that friends and relatives of Ronaiah Tuiasosopo, a 22-year-old who lives in California, believe he created Kekua. The website also reported Te'o and Tuiasosopo knew each other — which has led to questions about Te'o's involvement in the hoax.

Swarbrick understands why there are questions.

"They have every right to say that," Swarbrick said "Now I have some more information than they have. But they have every right to say that. ... I just ask those people to apply the same skepticism to everything about this. I have no doubt the perpetrators have a story they will yet spin about what went on here. I hope skepticism also greets that when they're articulating what that is."

Armstrong Tearful Over Telling Kids Truth

Lance Armstrong, 41, began to cry today as he described finding out his son Luke, 13, was publicly defending him from accusations that he doped during his cycling career.

Armstrong said that he knew, at that moment, that he would have to publicly admit to taking performance-enhancing drugs and having oxygen-boosting blood transfusions when competing in the Tour de France. He made those admissions to Oprah Winfrey in a two-part interview airing Thursday and tonight.

"When this all really started, I saw my son defending me, and saying, 'That's not true. What you're saying about my dad? That's not true,'" Armstrong said, tearing up during the second installment of his interview tonight. "And it almost goes to this question of, 'Why now?'

"That's when I knew I had to talk," Armstrong said. "He never asked me. He never said, 'Dad, is this true?' He trusted me."

He told Winfrey that he sat down with his children over the holidays to come clean about his drug use.

"I said, 'Listen, there's been a lot of questions about your dad, about my career and whether I doped or did not dope,'" he said he told them. "'I always denied that. I've always been ruthless and defiant about that, which is why you defended me, which makes it even sicker' I said, 'I want you to know that it's true.'"

He added that his mother was "a wreck" over the scandal.

Armstrong said that the lowest point in his fall from grace and the top of the cycling world came when his cancer charity, Livestrong, asked him to consider stepping down.

Lance Armstrong-Winfrey Interview: Doping Confession Watch Video

After the U.S. Anti-Doping Agency alleged in October that Armstrong doped throughout his reign as Tour de France champion, Armstrong said, his major sponsors -- including Nike, Anheuser Busch and Trek -- called one by one to end their endorsement contracts with him.

"Everybody out," he said. "Still not the most humbling moment."

Then came the call from Livestrong, the charity he founded at age 25 when he was diagnosed with testicular cancer.

"The story was getting out of control, which was my worst nightmare," he said. "I had this place in my mind that they would all leave. The one I didn't think would leave was the foundation.

"That was most humbling moment," he said.

Armstrong first stepped down as chairman of the board for the charity before being asked to end his association with the charity entirely. Livestrong is now run independently of Armstrong.

"I don't think it was 'We need you to step down,' but, 'We need you to consider stepping down for yourself,'" he said, recounting the call. "I had to think about that a lot. None of my kids, none of my friends have said, 'You're out,' and the foundation was like my sixth child. To make that decision, to step aside, that was big."

In Thursday's interview installment, the seven-time winner of the Tour de France admitted publicly for the first time that he doped throughout his career, confirming after months of angry denials the findings of the U.S. Anti-Doping Agency, which stripped him of his titles in October.

He told Winfrey that he was taking the opportunity to confess to everything he had done wrong, including for years angrily denying claims that he had doped.
