Armstrong's Lowest Point Was Quitting Livestrong

Lance Armstrong, 41, said tonight 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.

After the U.S. Anti-Doping Agency released a report in October 2012 alleging Armstrong doped throughout his reign as Tour de France champion, Armstrong said a second installment of an interview with Oprah Winfrey, 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."

Lance Armstrong-Winfrey Interview: How Honest Was He? Watch Video

Lance Armstrong-Winfrey Interview: Doping Confession Watch Video

In the first part of the interview, broadcast Thursday, Armstrong admitted for the first time that his decade-long dominance of cycling and seven wins in the Tour de France were owed, in part, to performance-enhancing drugs and oxygen-boosting blood transfusions.

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.

Armstrong said in the interview that he stopped doping following his 2005 Tour de France victory and did not use banned substances when he placed third in 2009 and entered the tour again in 2010.

Investigators familiar with Armstrong's case, however, told ABC News today that Armstrong did not come completely clean to Winfrey, and that they believed he doped in 2009.

They said that Armstrong's blood values at the 2009 race showed clear blood manipulation consistent with two transfusions. Armstrong's red blood cell count suddenly went up at these points, even though the number of baby red blood cells did not.

Investigators said that was proof that he received a transfusion of mature red blood cells.

If Armstrong lied about the 2009 race, it could be to protect himself criminally, investigators said.

Federal authorities looking to prosecute criminal cases will look back at the "last overt act" in which the crime was committed, they explained. If Armstrong doped in 2005 but not 2009, the statute of limitations may have expired on potential criminal activity.

The sources noted that there is no evidence right now that a criminal investigation will be reopened. Armstrong is facing at least three civil suits.

Matching names to genes: the end of genetic privacy?

Continue reading page

Are we being too free with our genetic information? What if you started receiving targeted ads for Prozac for the depression risk revealed by your publicly accessible genome? As increasing amounts of genetic information is placed online, many researchers believe that guaranteeing donors' privacy has become an impossible task.

The first major genetic data collection began in 2002 with the International HapMap Project – a collaborative effort to sequence genomes from families around the world. Its aim was to develop a public resource that will help researchers find genes associated with human disease and drug response.

While its consent form assured participants that their data would remain confidential, it had the foresight to mention that with future scientific advances, a deliberate attempt to match a genome with its donor might succeed. "The risk was felt to be very remote," says Laura Lyman Rodriguez of the US government's National Human Genome Research Institute in Bethesda, Maryland.

Their fears proved to be founded: in a paper published in Science this week, a team led by Yaniv Erlich of the Whitehead Institute in Cambridge, Massachusetts, used publicly available genetic information and an algorithm they developed to identify some of the people who donated their DNA to HapMap's successor, the 1000 Genomes Project.

Anonymity not guaranteed

Erlich says the research was inspired by a New Scientist article in which a 15-year-old boy successfully used unique genetic markers called short tandem repeats (STRs) on his Y chromosome to track down his father, who was an anonymous sperm donor. Erlich and his team used a similar approach.

First they turned to open-access genealogy databases, which attempt to link male relatives using matching surnames and similar STRs. The team chose a few surnames from these sources, such as "Venter",and then searched for the associated STRs in the 1000 Genomes Project's collection of whole genomes. This allowed them to identify which complete genomes were likely to be from people named Venter.

Although the 1000 Genome Project's database, which at last count had 1092 genomes, does not contain surname data, it does contain demographic data such as the ages and locations of its donors. By searching online phonebooks for people named Venter and narrowing those down to the geographic regions and ages represented in the whole genomes, the researchers were able to find the specific person who had donated his data.

In total, the researchers identified 50 individuals who had donated whole genomes. Some of these were female, whose identity was given away because of having the same location and age as a known donor's wife.

Matter of time

Before publishing their findings, the team warned the US National Institutes of Health (NIH) and other institutions involved in the project about the vulnerability in their data. Rodriguez says that they had been anticipating that someone would identify donors, "although we didn't know how or when".

To prevent Erlich's method from being used successfully again, age data has been removed from the project's website. Erlich says that this makes it difficult, although not impossible, to narrow the surnames down to an individual.

"The genie's out of the bottle," says Jeffrey Kahn of Florida State University in Tallahassee. "It's a harbinger of a changing paradigm of privacy." A cultural zeitgeist led by companies such as Facebook has led to more information sharing than anyone would have thought possible back in 2002 when HapMap first began, he says.

Recurring problem

This is not the first time genome confidentiality has been compromised. When James Watson made his genome public in 2007, he blanked out a gene related to Alzheimer's. But a group of researchers successfully inferred whether he carried the risky version of this gene by examining the DNA sequences on either side of the redacted gene.

While someone is bound to find another way to identify genetic donors, says Rodriguez, the NIH believes it would be wrong to remove all of their genome data from the public domain. She says that full accessibility is "very beneficial to science", but acknowledges that the project needs to strike a careful balance between confidentiality and open access.

It is especially pertinent, says Kahn, because genetic data does not just carry information from the person from whom it was taken. It can also reveal the genetic details of family members, some of whom might not want that information to be public. A relative's genome might reveal your own disease risk, for example, which you might not want to know or have an employer learn of. While laws prohibit health insurers and employers from discriminating against people based on their genetic data, it would not be difficult to give another reason for denying you a job.

An individual's relatives could not prevent that individual from learning about themselves, says Rodriguez, but researchers should encourage would-be genome donors to discuss the risks and benefits with their families.

Cycling: "One big lie" Armstrong says of 7 drug-fuelled Tours

LOS ANGELES: Lance Armstrong admitted his seven Tour de France titles were fuelled by an array of drugs, reversing years of denials in a televised interview with Oprah Winfrey broadcast Thursday.

Attempting to explain his drug-tainted past, Armstrong sat down with Winfrey for his first interview since being stripped last year of his record seven Tour titles and banned from sport for life.

It was recorded on Monday in Austin, Texas, and was to be aired in two segments on Thursday and Friday on Winfrey's OWN television channel.

"I know the truth. The truth isn't what was out there, the truth isn't what I said... This story was so perfect for so long... you overcome the disease, you win the Tour de France seven times, you have a happy marriage, you have children. I mean, it's just this mythic, perfect story," Armstrong said.

"And it wasn't true."

In an opening series of "yes" or "no" questions, Armstrong admitted using blood-boosting EPO, blood doping transfusions and testosterone or human growth hormone.

Armstrong told Winfrey he didn't believe it was possible to win the Tour in the years he raced without doping, and challenged the characterisation of the doping program on his US Postal Service team as the most sophisticated ever.

Hours before the kickoff, Armstrong saw another accolade withdrawn as the International Olympic Committee said it had asked him to return the cycling time-trial bronze medal he won in 2000.

The International Cycling Union last year upheld the US Anti-Doping Agency's ban of Armstrong, and the revocation of his cycling results from August 1998, but the IOC waited for three weeks to see if Armstrong planned an appeal.

While Winfrey confirmed on Tuesday reports that Armstrong had admitted using banned performance enhancers in their talk, little else was known of what he would reveal.

Speculation swirled as to whether he had implicated others -- notably members of the sport's world governing body -- amid allegations of complicity and cover-up.

The difficulty of untangling the doping web in cycling was again clear when the IOC's move recalled the 2000 Olympic time-trial medallists.

Abraham Olano of Spain, who was fourth, could inherit the bronze after finishing fourth in a race won by Armstrong's ex-US Post Service team-mate Viasheslav Ekimov, with Germany's Jan Ullrich taking silver.

Ekimov is now general manager of the Katusha cycling team that were dropped from the elite ProTeam list for this season because of their ambivalent stance on doping, and Ullrich eventually served a two-year ban for doping.

Some have speculated that Armstrong might attempt to rationalize doping as standard procedure in the years of his cycling career.

Certainly his admission, and his choice of the famously sympathetic Winfrey as confessor, are an about face after years of aggressive denials and often vitriolic attacks on those who doubted him.

"No one could have imagined only a few weeks ago that Lance Armstrong would make his confession publicly, that he would confess in public to having been doped," Tour de France director Christian Prudhomme told reporters in Paris.

"It's obviously something very important but I can't say more than that ... For us, Lance Armstrong is already in the past."

This week's exercise, however, is about the future, with Armstrong reportedly seeking a way back into sports and those in cycling wondering just who will be implicated in his revelations.

Prepare for 'bad news' in hostage crisis, official says

STORY HIGHLIGHTS

• NEW: A Belfast man says his brother had explosives around his neck when he escaped


• Islamist militants take Algerian and foreign hostages at a gas plant in Algeria


• British, Norwegian, U.S. and Japanese citizens are among those held hostage


• "There are still hostages, and there are still terrorists," a senior U.S. official says

(CNN) -- British Prime Minister David Cameron warned his compatriots to prepare for "bad news ahead" related to kidnapping of dozens of hostages at a gas facility in Algeria.

Nearly 600 workers and four foreign nationals -- two Scots, a Kenyan and a French citizen -- were free by late Thursday after an operation launched by Algeria's military, according to the state-run Algerian Press Service.

Some hostages were still presumably being held, and the crisis is far from over.

"It is a fluid situation, it is ongoing," Cameron told the Reuters news agency. "But I think we should be prepared for the possibility of further bad news, very difficult news, in this extremely difficult situation."

The Algerian military operation was over by Thursday evening, according to the Algerian Press Service. At that point, there was no immediate indication as to how many had been killed or injured, how many hostages were still being held, what their condition was or if future action would be taken.

The military operation led to numerous casualties, though the exact number wasn't known, APS reported. Two people -- an Algerian and British national -- died when the kidnappers attacked Wednesday, according to the same news agency. Cameron acknowledged, in his Reuters interview, that a British citizen "very sadly died."

While the Algerian military raid wrapped up on Thursday, a senior U.S. official stressed later that night that more military operations could be coming.

"There are still hostages, and there are still terrorists," the official said. "So tomorrow is another day."

Algerians and foreign workers were taken hostage at the gas plant in Wednesday's assault, apparently in direct response to France's offensive in nearby Mali. The gas field is 60 kilometers (40 miles) west of the Libyan border and 1,300 kilometers (about 800 miles) from the Algerian capital, Algiers.

The kidnappers have AK-47 rifles and put explosives-laden vests on some of the hostages, a U.S. State Department official said. It is not clear whether the hostage-takers wore the suicide vests when they staged the action, another U.S. official said.

Islamists take foreign hostages in attack on Algerian oil field

The attackers put the number of hostages at "more than 40," including seven Americans, two French, two British and other Europeans. Another Islamist group told the Mauritanian News Agency there were 41 "Westerners."

The APS, though, reported that just over 20 foreign nationals were being held.

Officials from Norway, the United States, Japan and Great Britain have said some of their nationals are among the hostages.

Nine Norwegian employees of Statoil are unaccounted for, while five Norwegian nationals -- as well as three Algerians -- who work for the company are safe, the company said in a statement.

CNN affiliate BFM-TV reported that a French citizen, who is a nurse who worked on the site, was recently freed. CNN could not independently confirm the report.

Former hostage Stephen McFaul had plastic explosives strapped around his neck, duct tape over his mouth and rope around his hands, his brother Brian McFaul told CNN from Belfast.

McFaul made a break for freedom after the vehicle he was in -- one of several targeted by Algerian fighters -- crashed, with the explosives still around his neck.

"The joy was unreal," Brian McFaul said upon hearing his brother was safe. "I haven't seen my mother move as fast in all my life, and my mother smile as much, hugging each other ... You couldn't describe the feeling."

An unspecified number of Americans are among the hostages held by terrorists at BP's In Amenas facility in Algeria, White House spokesman Jay Carney said. There could be as few as three American hostages, two U.S. officials said Wednesday.

One of the kidnapped Americans is a Texas man, a family member told CNN.

By Thursday night, some Americans had been freed and spoke with family members back home, while others remained unaccounted for, U.S. officials said.

"This incident will be resolved -- we hope -- with a minimum loss of life," said U.S. Secretary of State Hillary Clinton. "But when you deal with these relentless terrorists, life is not in any way precious to them."

Heavy clashes and drones

The man behind the group claiming responsibility for the attack and kidnappings is a veteran jihadist known for seizing hostages.

Moktar Belmoktar, an Algerian who lost an eye fighting in Afghanistan in his teens, has long been a target of French counterterrorism forces. Libyan sources said he spent several months in Libya in 2011, exploring cooperation with local jihadist groups and securing weapons.

Algerian forces launched their operation upon noticing the hostages being moved toward "a neighboring country," where kidnappers could use them "as a means of blackmail with criminal intent," Algerian Communications Minister Mohamed Said said Thursday on state TV.

Algerian troops fired on at least two SUVs trying to leave the kidnapping site, Algerian radio said, citing local sources. And an Algerian reporter saw heavy clashes near the site, APS and radio reports said.

"There were a number of dead and injured, we don't have a final figure," Said said.

An unarmed Predator drone has flown over the plant to gather intelligence, a U.S. official said Thursday. Satellite imagery was taken previously.

Earlier, Algeria's state media reported that all Algerian nationals who had been held hostage were free: some had fled, while others were released. The hostages still detained are foreigners, Algerian Interior Minister Dahou Ould Kablia said.

In addition to the hundreds of freed workers, 30 Algerian workers escaped -- recovered by helicopters flying over the site -- according to the GPS report.

Meanwhile, two oil companies that operated at the site -- BP and Statoil -- are pulling all of their non-essential personnel from Algeria.

"Our focus is 100 percent on the safety and welfare of those people and their families, and we are now beginning a staged and planned reduction in non-essential workforce on a temporary basis, pulling them out of the country," said BP Vice President Peter Maher from London's Gatwick Airport, where a chartered flight from Algeria was set to arrive Thursday night.

Militants blame Algeria for letting French use its air space

The militants said they carried out the operation because Algeria allowed French forces to use its air space in attacking Islamist militants in Mali. Media in the region reported that the attackers issued a statement demanding an end to "brutal aggression on our people in Mali" and cited "blatant intervention of the French crusader forces in Mali."

The fallout escalated after rebels kidnapped the Westerners, dragging governments beyond Africa into the region's conflicts and insecurity.

U.S. Defense Secretary Leon Panetta, in Europe meeting with NATO allies, called the hostage-taking "a terrorist act."

Japan and the United Kingdom sent officials to Algeria to get the latest information. French President Francois Hollande earlier confirmed the presence of French citizens on site but would not say whether any were hostages.

Cameron -- who canceled a Friday speech in the Netherlands -- talked with U.S. President Barack Obama about the situation Thursday, according to a Downing Street statement.

Before Algeria launched its military operation, U.S. officials urged the Algerians to be cautious and make the hostages' safety their first priority, an Obama administration official said.

However, Algerian government officials did not tell their U.S. counterparts in advance about their military raid, according to the official.

A senior U.S. official said, at this point, the United States doesn't trust the information it is getting from the Algerians, "because we hear one thing and then we hear something else."

There are also fears that the tactics used by the Algerian forces may have put hostages in jeopardy, though the official acknowledged they could have hit even harder.

"In all fairness, they could have ended it today," the senior U.S. official said. "They haven't used all the severeness they could. They know hostages are left."

CNN's Joe Sterling and Greg Botelho wrote this story from Atlanta. CNN's Elise Labott, David Mattingly, Athena Jones, Barbara Starr, Jethro Mullen, Tim Lister and Faith Karimi contributed to this report, as did journalists Peter Taggert from Belfast Said Ben Ali contributed from Algiers.

Manti Te'o kept girlfriend myth alive after revelation

SOUTH BEND, Ind. Not once but twice after he supposedly discovered his online girlfriend of three years never even existed, Notre Dame All-American linebacker Manti Te'o perpetuated the heartbreaking story about her death.

13 Photos

Manti Te'o

An Associated Press review of news coverage found that the Heisman Trophy runner-up talked about his doomed love in a Web interview on Dec. 8 and again in a newspaper interview published Dec. 11. He and the university said Wednesday that he learned on Dec. 6 that it was all a hoax, that not only wasn't she dead, she wasn't real.

On Thursday, a day after Te'o's inspiring, playing-through-heartache story was exposed as a bizarre lie, Te'o and Notre Dame faced questions from sports writers and fans about whether he really was duped, as he claimed, or whether he and the university were complicit in the hoax and misled the public, perhaps to improve his chances of winning the Heisman.

Yahoo sports columnist Dan Wetzel said the case has "left everyone wondering whether this was really the case of a naJive football player done wrong by friends or a fabrication that has yet to play to its conclusion."

Gregg Doyel, national columnist for CBSSports.com, was more direct.

"Nothing about this story has been comprehensible, or logical, and that extends to what happens next," he wrote. "I cannot comprehend Manti Te'o saying anything that could make me believe he was a victim."

On Wednesday, Te'o and Notre Dame athletic director Jack Swarbrick said the player was drawn into a virtual romance with a woman who used the phony name Lennay Kekua, and was fooled into believing she died of leukemia in September. They said his only contact with the woman was via the Internet and telephone.

Te'o also lost his grandmother — for real — the same day his girlfriend supposedly died, and his role in leading Notre Dame to its best season in decades endeared him to fans and put him at the center of college football's biggest feel-good story of the year.

Relying on information provided by Te'o's family members, the South Bend Tribune reported in October that Te'o and Kekua first met, in person, in 2009, and that the two had also gotten together in Hawaii, where Te'o grew up.

Te'o never mentioned a face-to-face meeting with Kekua in public comments reviewed by the AP. And an AP review of media reports about Te'o since Sept. 13 turned up no instance in which he directly confirmed or denied those stories — until Wednesday.

Among the outstanding questions Thursday: Why didn't Te'o ever clarify the nature of his relationship as the story took on a life of its own?

Te'o's agent, Tom Condon, said the athlete had no plans to make any public statements Thursday in Bradenton, Fla., where he has been training with other NFL hopefuls at the IMG Academy.

Notre Dame said Te'o found out that Kekau was not a real person through a phone call he received at an awards ceremony in Orlando, Fla., on Dec. 6. He told Notre Dame coaches about the situation on Dec. 26.

Manti Te'o's girlfriend hoax: How did it happen?

The AP's media review turned up two instances during that gap when the football star mentioned Kekua in public.

Te'o was in New York for the Heisman presentation on Dec. 8 and, during an interview before the ceremony that ran on the WSBT.com, the website for a South Bend TV station, Te'o said: "I mean, I don't like cancer at all. I lost both my grandparents and my girlfriend to cancer. So I've really tried to go to children's hospitals and see, you know, children."

In a story that ran in the Daily Press of Newport News, Va., on Dec. 11, Te'o recounted why he played a few days after he found out Kekau died in September, and the day she was supposedly buried.

"She made me promise, when it happened, that I would stay and play," he said.

On Wednesday, Swarbrick said Notre Dame did not go public with its findings sooner because it expected the Te'o family to come forward first. But Deadspin.com broke the story Wednesday.

Reporters were turned away Thursday at the main gate of IMG's sprawling, secure complex. Te'o remained on the grounds, said a person familiar with situation who spoke on condition of anonymity because neither Te'o nor IMG authorized the release of the information.

"This whole thing is so nutsy that I believe it only could have happened at Notre Dame, where mythology trumps common sense on a daily basis. ... Given the choice between reality and fiction, Notre Dame always will choose fiction," sports writer Rick Telander said in the Chicago Sun-Times.

"Which brings me to what I believe is the real reason Te'o and apparently his father, at least went along with this scheme: the Heisman Trophy.

Chicago Tribune columnist John Kass blasted both Te'o and Notre Dame.

"When your girlfriend dying of leukemia after suffering a car crash tells you she loves you, even if it might help you win the Heisman Trophy, you check it out," he said.

He said the university's failure to call a news conference and go public sooner means "Notre Dame is complicit in the lie."

"The school fell in love with the Te'o girlfriend myth," he wrote.

Lance Armstrong Confesses to Doping

Lance Armstrong, formerly cycling's most decorated champion and considered one of America's greatest athletes, confessed to cheating for at least a decade, admitting on Thursday that he owed all seven of his Tour de France titles and the millions of dollars in endorsements that followed to his use of illicit performance-enhancing drugs.

After years of denying that he had taken banned drugs and received oxygen-boosting blood transfusions, and attacking his teammates and competitors who attempted to expose him, Armstrong came clean with Oprah Winfrey in an exclusive interview, confessing to using banned substances for decades.

"I view this situation as one big lie that I repeated a lot of times," he said.

In October, the U.S. Anti-Doping Agency issued a report in which 11 former teammates exposed the system with which they and Armstrong received drugs with the knowledge of their coaches and help of team physicians.

The U.S. Postal Service Cycling Team "ran the most sophisticated, professionalized and successful doping program that sport has ever seen," USADA said in its report.

Armstrong said he was driven to cheat by a "ruthless desire to win."

He told Winfrey that his competition "cocktail" consisted of EPO, blood transfusions and testosterone, and that he had previously used cortisone.

He said he stopped doping following his 2005 Tour de France victory and did not use banned substances when he placed third in 2009 and entered the race again in 2010.

"It was a mythic perfect story and it wasn't true," Armstrong said of his fairytale story of overcoming testicular cancer to become the most celebrated cyclist in history.

Armstrong would not name other members of his team who doped, but admitted that as the team's captain he set an example. He admitted he was "a bully" but said there "there was a never a directive," from him that his teammates had to use banned substances.

"At the time it did not feel wrong?" Winfrey asked.

"No," Armstrong said. "Scary."

"Did you feel bad about it?" she asked again.

"No," he said.

Also on Thursday, before the Winfrey interview aired, the International Olympic Committee stripped Armstrong his of 2000 Olympic bronze medal.

NASA buys blow-up habitat for space station astronauts

NASA wants to blow up part of the International Space Station – and a Las Vegas firm is eager to help.

The US space agency has signed a $17.8-million contract with Bigelow Aerospace of Nevada to build an inflatable crew habitat for the ISS.

According to details released today at a press briefing , the Bigelow Expandable Activity Module, or BEAM, will launch in 2015. Astronauts on the ISS will test the module for safety and comfort.

BEAM will fly uninflated inside the trunk of a SpaceX Dragon capsule. Once docked and fully expanded, the module will be 4 metres long and 3 metres wide. For two years astronauts will monitor conditions inside, such as temperature and radiation levels.

Bigelow hopes the tests done in orbit will prove that inflatable capsules are safe and reliable for space tourists and commercial research, an idea almost as old as NASA itself. The space agency began investigating the concept of expandable spacecraft in 1958. Space stations like this would be easier to launch and assemble than those with metal components, so would be cheaper. But research ended after a budget crunch in 2000, and Bigelow licensed the technology from NASA.

Stronger skin

The company has made progress, developing shielding that resists punctures from space debris and micrometeorites. BEAM's skin, for instance, is made from layers of material like Kevlar to protect occupants from high-speed impacts. The craft's skin has been tested in the lab alongside shielding used right now on the rest of the ISS, says Bigelow director Mike Gold.

"Our envelope will not only equal but be superior to what is flying on the ISS today. We have a strong and absolute focus on safety," he says.

And we have to be sure that inflatable craft are safe, says William Schonberg, an engineer specialising in orbital debris protection at Missouri University of Science and Technology in Rolla. "The overall risk to the ISS is the sum of the risks of its individual components," he says.

It may seem counter-intuitive, but a flexible, inflatable design is just as likely to survive punishment from space debris as metal shielding, says Schonberg. "Certain composite cloth materials have been shown to be highly effective as shields against [high-speed space] impacts. So depending on what material is used, and in what combination it is used with other materials – such as thermal insulation blankets – the final design could be just as effective and perhaps better than the more traditional all-metal shields used elsewhere on the station."

Gold hopes BEAM will also demonstrate that fabric shielding can limit radiation risks. This is a major worry on missions to the moon or an asteroid say, where astronauts have to spend weeks or months outside Earth's protective magnetic field.

High-energy particles called cosmic rays constantly fly through the solar system, and when they strike metal shielding, they can emit secondary radiation in the form of X-rays. This doesn't happen with Kevlar-based fabric shields and so expandable habitats could be more desirable for travellers heading deeper into space, says Gold.

Football: Hodgson eyes long-awaited England glory

LONDON: As the Football Association begins its 150th anniversary year, England manager Roy Hodgson has challenged his players to provide the ultimate celebration by at least putting themselves in contention to end almost half a century without a trophy.

Hodgson is the latest in a string of managers charged with ending England's wait for a first major honour since their lone World Cup final triumph, against the then West Germany at London's Wembley Stadium in 1966.

But after helping the FA launch its landmark birthday on the London site of its first meeting, the current incumbent in the so-called 'impossible job' refused to accept it may take another 50 years to replicate.

"There's always hope," Hodgson insisted. "Hope springs eternal. But what you have to do to win tournaments is make sure you're regularly among the ones who are up there with a possibility of winning.

"You could compare it to someone who is an amateur darts player. The more darts he throws in and around the centre, one day he will get it in the bullseye.

"If he's spreading them around the board your chances will be less than if he's getting them in the 25 circle."

Hodgson took England to the quarter-finals at Euro 2012, only losing on penalties to Italy -- even though his team's performances were often described as limited by many critics who yearn for England to rely more on technique and finesse than just their famous bulldog spirit.

The FA shares the same ambition; which is why it has built a national academy in central England at St George's Park -- a school for coaches where all 24 national teams will also be based.

And although Hodgson knows any rewards from that venture are a long way down the line, he hasn't ruled out a degree of short-term success if England qualify for the 2014 World Cup finals in Brazil.

"The first thing we have to do of course is qualify for the tournament," he said. "And then when we qualify it will be important that we give a very good account of ourselves at the World Cup in Brazil. And who knows, once you are there you have a chance of winning it.

"I think we have some very good young players coming into the game playing regularly now and showing that they do have the ability to shoulder the burden."

Hodgson was joined at The FA's anniversary launch by several former England managers including Sven-Goran Eriksson, Terry Venables and Fabio Capello, who left the role in controversial circumstances following a row over a decision to strip John Terry of the England captaincy.

But the Italian was all smiles as he said: "We are all friends now. It is very good to come back and see the people I used to work with. I have no problems with anyone.

"You know I can't talk about what happened with England but I am enjoying my life with Russia and my hope is that we play England in Brazil at the World Cup. That would be very good I think."

FA chairman David Bernstein welcomed Capello's participation by insisting: "Fabio is a man of great dignity and I respect him enormously.

"To see him today (Wednesday) and the warmth he showed, and there was a great deal of warmth when we met each other was really fabulous. It's the way it should be. There were hugs all round."

Meanwhile it emerged the FA, which has already arranged anniversary England friendlies against Brazil, Scotland and the Republic of Ireland, was also looking to fit in matches against Argentina and Germany at Wembley in October and November.

STORY HIGHLIGHTS

• Te'o's father had said his son, girlfriend had met at his home in Hawaii

• Sports website Deadspin raises questions about the existence of his girlfriend


• In September, Te'o talked about losing his grandmother, girlfriend in the same week

(CNN) -- Notre Dame linebacker Manti Te'o said Wednesday he was the victim of a "sick joke" that had him and legions of fans believing in a "girlfriend" who may never have existed.

Te'o was the subject of an inspirational story that had him overcoming the deaths of his real-life grandmother and his "girlfriend" as his team marched toward the BCS National Championship Game.

Te'o released a statement and Notre Dame held a news conference Wednesday night after the sports website Deadspin published an article that called the girlfriend story a "hoax."

Last September and October, Te'o told interviewers the losses of the women, who reportedly died within hours of each other, inspired him to honor them with sterling play on the field.

"I miss 'em, but I know that I'll see them again one day," he told ESPN.

That and other media reports led to a gripping human interest story of determination. The girlfriend was identified as Lennay Kekua.

Jack Swarbrick, director of athletics at Notre Dame, told reporters that Te'o was the victim of an elaborate hoax. "And he will carry that with him for a while," Swarbrick said.

Notre Dame said the relationship between Te'o and the supposed girlfriend was exclusively online.

As part of the hoax, several meetings were set up, including at Te'o's home in Hawaii, but Kekua never showed, Swarbrick said.

Te'o's father, Brian, told the South Bend (Indiana) Tribune last fall that his son did have the opportunity to meet Lennay.

"They started out as just friends," Brian Te'o said, according to the newspaper. "Every once in a while, she would travel to Hawaii, and that happened to be the time Manti was home, so he would meet with her there. But within the last year, they became a couple."

According to Swarbrick, Te'o in early December received a call from a woman claiming to be his girlfriend and telling him she was not dead. Those calls continued but Te'o did not answer, Swarbrick said.

Te'o's grandmother did in fact die in September, according to Deadspin, but there is no Social Security Administration record of the death of the athlete's supposed girlfriend, described as a Stanford University student.

Stanford University's registrar's office told CNN that it has never had a student registered by Kekua's name or an alternative spelling.

"Outside of a few Twitter and Instagram accounts, there's no online evidence that Lennay Kekua ever existed," Deadspin contends. "There was no Lennay Kekua."

According to the website, Kekua, 22, had reportedly been in a serious auto accident in California and was later diagnosed with leukemia.

Photographs showing a young woman identified as Kekua in online tributes and news reports actually are photos from social media accounts of a 22-year-old California woman who is not named Lennay Kekua and does not have leukemia, according to Deadspin. The woman never met Te'o, it said.

Your opinion: What do you think?

After Notre Dame upset No. 10 Michigan State on September 15, Te'o told ABC about his late grandmother and girlfriend.

"They were with me. I couldn't do it without them," Te'o said. "I couldn't do it without the support of my family and my girlfriend's family."

"I'm so happy that I had a chance to honor my grandma and my family and my girlfriend," the Heisman Trophy runner-up said. "That's what it's all about, family."

Timothy Burke, co-author of the Deadspin article, told Miami sports radio host Dan Le Batard, "We got an e-mail last week saying something isn't right" with the girlfriend story.

Te'o, the runner-up for the Heisman Trophy, said Wednesday he "developed an emotional relationship with a woman I met online. We maintained what I thought to be an authentic relationship by communicating frequently online and on the phone, and I grew to care deeply about her."

In his statement reported by ESPN, the star said, "To realize that I was the victim of what was apparently someone's sick joke and constant lies was, and is, painful and humiliating.

"It further pains me that the grief I felt and the sympathies expressed to me at the time of my grandmother's death in September were in any way deepened by what I believed to be another significant loss in my life."

Notre Dame said it hired an independent investigative firm to look into the situation.

Swarbrick said the independent investigation found that the perpetrators were involved in "online chatter" indicating that it was a hoax, and Te'o was a victim.

"I will refer you to the documentary 'Catfish,'" the athletic director said. "It's ... about people tricking people online by pretending to be other people."

MTV broadcasts a show about such online trickery.

Swarbrick said he met with Te'o's family two days before Notre Dame played in the January 7 championship game and lost to Alabama. The linebacker is expected to be a first-round pick in the NFL draft this spring.

CNN's Steve Almasy, Amanda Watts and Phil Gast contributed to this report.

Manti Te'o says he's the victim of "girlfriend" hoax

Updated 9:55 p.m. ET

SOUTH BEND, Ind. Notre Dame said a story that star Manti Te'o's girlfriend had died of leukemia — a loss he said inspired him all season and helped him lead the Irish to the BCS title game — turned out to be a hoax apparently perpetrated against the linebacker.

Notre Dame Fighting Irish Athletic Director Jack Swarbrick held a press conference late Wednesday about the apparent hoax Wednesday after Deadspin.com said it could find no record that Lennay Kekua ever existed.

"This was a very elaborate, very sophisticated hoax perpetrated for reasons we cant fully understand," Swarbrick said.

CBS News and its morning program, "CBS This Morning," were among the many news outlets that reported on the "hoax" girlfriend's death. "CBS This Morning" will have an update on the report Thursday.

The Notre Dame athletic director insisted "several things" led him to believe Te'o did not create the girlfriend himself after the university's investigation into the situation, led by a private investigative firm.

"Manti was the victim of that hoax. He has to carry that with him for a while. In many ways, Manti was the perfect mark because he's the guy who was so willing to believe in others," Swarbrick said. "The pain was real. The grieving was real. The affection was real."

By Te'o's own account, she was an "online" girlfriend.

"This is incredibly embarrassing to talk about, but over an extended period of time, I developed an emotional relationship with a woman I met online. We maintained what I thought to be an authentic relationship by communicating frequently online and on the phone, and I grew to care deeply about her," he said in statement.

"To realize that I was the victim of what was apparently someone's sick joke and constant lies was, and is, painful and humiliating."

"In retrospect, I obviously should have been much more cautious. If anything good comes of this, I hope it is that others will be far more guarded when they engage with people online than I was."

The linebacker's father, Brian Te'o, said in a telephone interview with The Associated Press in early October that he and his wife had never met Kekua, saying they were hoping to meet her at the Wake Forest game in November. The father said he believed the relationship was just beginning to get serious when she died.

Swarbrick likened the situation to the 2010 movie "Catfish," in which "young filmmakers document their colleague's budding online friendship" with an allegedly young woman that turns out also to be a hoax.

The university said its coaches were informed by Te'o and his parents on Dec. 26 that Te'o had been the victim of what appeared to be a hoax.

Someone using a fictitious name "apparently ingratiated herself with Manti and then conspired with others to lead him to believe she had tragically died of leukemia," the school said.

Swarbrick said the investigation revealed "several" perpetrators, although the exact number is unclear. He said the university became convinced of the hoax based on "the joy they were taking...referring to what they accomplished and what they had done."

The week before Notre Dame played Michigan State on Sept. 15, coach Brian Kelly told reporters that Te'o's grandmother and a friend had died. Te'o didn't miss the game. He said Kekua had told him not to miss a game if she died. Te'o turned in one of his best performances of the season in the 20-3 victory in East Lansing, and his playing through heartache became a prominent theme during the Irish's undefeated regular season.

Te'o went on the become a Heisman Trophy finalist, finishing second in the voting, and leading Notre Dame to its first appearance in the BCS championship.

Te'o and the Irish lost the title game to Alabama, 42-14 on Jan. 7. He has graduated and was set to begin preparing for the NFL combine and draft at the IMG Academy in Bradenton, Fla., this week.

Four days ago Te'o posted on his Twitter account: "Can't wait to start training with the guys! Workin to be the best! The grind continues! (hash)Future"

Te'o's statement also said: "It further pains me that the grief I felt and the sympathies expressed to me at the time of my grandmother's death in September were in any way deepened by what I believed to be another significant loss in my life.

"I am enormously grateful for the support of my family, friends and Notre Dame fans throughout this year. To think that I shared with them my happiness about my relationship and details that I thought to be true about her just makes me sick. I hope that people can understand how trying and confusing this whole experience has been.

"Fortunately, I have many wonderful things in my life, and I'm looking forward to putting this painful experience behind me as I focus on preparing for the NFL Draft."
