The digital map is not the territory

WHEN Google Maps launched in 2005, the reaction in some quarters was puzzlement. Why was a search engine getting into cartography? The answer became apparent as it rapidly enhanced the service with navigation, Street View, local business listings and so on. Google doesn't just want to catalogue the online world; it wants to know where everything is in the physical world, too.

Eight years on, that goal looks within reach. Google and its competitors now offer maps of the depths of the oceans and the far side of the Moon. They help their users to navigate everywhere from side streets to shopping malls. And they have revolutionised the way we think about location - putting us, rather than some culturally significant but geographically arbitrary prime meridian, at the centre of the map (see "Uncharted territory: Where digital maps are leading us").

This innovation has made digital maps all but indispensable to millions of people. They provide an alternative view of the world: one that offers suggestions about directions and places. They are also becoming one of the primary tools for exploring the wealth of civic data now available about our surroundings, from crime statistics to traffic flows.

When the maps turn out to be wrong, though, we feel betrayed: witness the rare bloody nose dealt to Apple when it recently unveiled a buggy iPhone map app.

Such trust issues hint at bigger battles to come. Many of today's wondrous maps are powered by deep-pocketed companies, each claiming to offer the ultimate in verisimilitude. But many details of their construction are trade secrets. This matters because all maps have their quirks and biases. Consider the Mercator projection, breakthrough mapping of a different age: it helped make global exploration possible, but grossly distorts the land area of different countries.

More than 80 years ago, the philosopher Alfred Korzybski observed that "the map is not the territory". A representation of reality, no matter how faithful it may seem, is not the same thing as reality itself. We should be mindful of that distinction as digital mapping evolves.

Funerals for six protesters killed by Iraq troops

FALLUJAH, Iraq: Funerals were to be held on Saturday for six anti-government demonstrators killed by Iraqi troops during a rally in Fallujah a day earlier, sharply raising tensions amid weeks of angry rallies.

The deaths in the predominantly Sunni town west of Baghdad were the first since protests began last month, and came as tens of thousands rallied in Sunni areas of the country, railing against alleged targeting of their minority by the Shiite-led authorities.

While some Shiite clerics gave cross-sectarian support to the protests, Prime Minister Nuri al-Maliki blamed demonstrators for "raising tensions" and insisted soldiers had been "attacked".

Friday's rally had been moving from central to eastern Fallujah, 60 kilometres (35 miles) from Baghdad, but was blocked off by soldiers, police captain Nasser Awad said.

Protesters then began throwing bottles of water at the troops, who opened fire.

Six demonstrators were killed, all of them from gunshot wounds, said Khaled Khalaf al-Rawi, a doctor at Fallujah hospital. Rawi said 35 were wounded, the majority by gunfire.

Defence ministry spokesman Major General Mohammed al-Askari said an inquiry had begun, and pledged that victims would be financially compensated.

Officials in Fallujah earlier said the army had vacated the town and had been ordered to transfer security responsibility to the police.

Maliki called for restraint by security forces in a statement issued by his office, but also said soldiers had been attacked in the first place.

"This is what Al-Qaeda and terrorist groups are seeking to exploit," he said, referring to apparent sectarian tensions.

Along with protests in Fallujah on Friday, large demonstrations also took place in several other Sunni cities in north and west Iraq, as well as in Sunni neighbourhoods of Baghdad.

The protests have hardened opposition against Maliki and come amid a political crisis less than three months ahead of key provincial elections.

21 sentenced to death over 2012 soccer riot

Egyptian protesters take part in a demonstration near the prison in city of Port Said on January 25.

STORY HIGHLIGHTS

• NEW: Forces clashed with family members of those convicted


• Known as the "massacre of Port Said," 74 people were killed in the riot


• The violence occurred at the conclusion of a football match in Port Said last year


• The sentences were handed down in a packed courtroom

(CNN) -- An Egyptian judge sentenced 21 people to death Saturday for their roles in a football game riot last year, a ruling that sparked violent clashes between security forces and relatives of the convicted.

The riot in Port Said left 74 people dead and more than 1,000 wounded.

Security forces and family members clashed outside the prison in the northeastern port city, where authorities accused some of attempting to storm the building to free their loved ones, state-run Nile TV reported.

"There is a state of anger on the streets of Port Said, and the security forces are on high alert," Nile TV reported.

The crowd fired guns and hurled rocks at the security forces, who in turn used tear gas to disperse the crowd, according to state-run media.

The sentences were handed down in a packed courtroom in Cairo as victims' relatives and those convicted wept.

"I thank God that justice is back in the courts of Egypt. Many mothers will sleep sound tonight knowing justice is served," the mother of Mustafa Issam, who was killed in the riots, told Nile TV by phone.

The sentences must be reviewed by Egypt's highest religious authority, who will return his opinion to the court March 9. On that day, an additional 54 defendants in the case will also be sentenced, the judge said.

Dubbed the "massacre at Port Said" by Egyptian media, the riot broke out on February 1, 2012, after Port Said-based Al-Masry defeated Cairo's Al-Ahly, 3-1.

When the clashes began, about 22,000 people were inside the stadium, which can hold up to 25,000 people. About 2,000 Al-Ahly fans were at the game, authorities said.

Fans from both sides bashed each other with rocks and chairs. Many of those who died fell from the bleachers during the melee inside the stadium, while others suffocated.

It was unclear whether intense sports rivalries or political strife sparked the riots, though witnesses said tension was building through the game with Port Said fans throwing bottles and rocks at players on the Cairo team.

During Egypt's revolution that ended with the toppling of Hosni Mubarak, football fans became a powerful force for political change, according to CNN contributor James Montague, who wrote the book "When Friday Comes: Football in the War Zone."

Even so, the riots occurred at a time when Egypt was struggling with a security vacuum following Mubarak's ouster.

In the hours after the riot in Port Said, protesters in Cairo chanted, "Down with military rule." At the time, the secretary-general of the Muslim Brotherhood party blamed Egypt's military for the deaths.

Egypt's interior ministry blamed fans for provoking police.

Witnesses said police did little to try to quell the clashes.

Notre Dame president defends handling of Te'o case

SOUTH BEND, Ind. Top administrators at Notre Dame decided within hours of hearing about the Manti Te'o dead girlfriend hoax that it did not involve a crime and within two days had concluded there was no NCAA violation, according to a letter sent by the university president to board of trustee members on Friday.

The Rev. John Jenkins told trustees that despite "the unrelenting scrutiny of hundreds of journalists and countless others — and repeated attempts by some to create a different impression- no facts relating to the hoax have been at odds with what Manti told us" on Dec. 27-28.

The letter was obtained Friday by The Associated Press from a university official who provided it on condition of anonymity because the private school's internal workings are confidential.

The eight-page document, including a four-page letter from Jenkins and a four-page outline of how Notre Dame handled the hoax, is both a defense and an explanation of the school's actions.

"We did our best to get to the truth in extraordinary circumstances, be good stewards of the interests of the university and its good name and — as we do in all things — to make the well-being of our students one of our very highest priorities," Jenkins concluded in his letter.

Some of the timeline Notre Dame outlined is well known, including that its star linebacker disclosed the scam to his coaches the day after Christmas and it remained unknown to the public until Deadspin.com broke the story on Jan. 16, long after the Fighting Irish lost the BCS championship to Alabama on Jan. 7.

Jenkins wrote that Notre Dame officials talked in the hours after hearing from Te'o on Dec. 26 and agreed there was no indication of a crime or student conduct code violation. Athletic director Jack Swarbrick spoke with Te'o the next day, and on Dec. 28 the school concluded there were no indications of an NCAA rules violation, which could have put Notre Dame's 12-0 regular season in jeopardy.

The school then made moves to find out who was behind the hoax, thereby protecting Te'o and itself.

"For the first couple of days after receiving the news from Manti, there was considerable confusion and we simply did not know what there was to disclose," Jenkins wrote.

Manti Te'o

On Jan. 2, after several days of internal discussion and a week after Te'o's disclosure, Notre Dame retained Stroz Friedberg, a New York computer forensics firm to investigate the case and whether any other football players had been targeted. The firm did not return phone or email messages left Friday.

Notre Dame officials believed Te'o's girlfriend — whether alive or dead — was at least a real person until the next day, when Stroz Friedberg said it could not find any evidence that Kekua or most of her relatives ever existed. And by Jan. 4, two days after hiring Stroz Friedberg, Notre Dame officials concluded Te'o was the victim of the hoax, there was no threat to the school and the private investigation was suspended.

"We concluded that this matter was personal to Manti," Jenkins wrote, deciding it was up to Te'o to disclose, especially after he signed with Creative Artists Agency on the day after the BCS game.

WH, Senators to Begin Push on Immigration Reform

The White House and a bipartisan group of senators next week plan to begin their efforts to push for comprehensive immigration reform.

President Barack Obama will make an announcement on immigration during a Tuesday trip to Las Vegas, Nevada, the White House said on Friday. The Senate group is expected make their plans public around the same time, the Associated Press reported.

For Obama, immigration reform is a campaign promise that has remained unfulfilled from his first White House run in 2008. During his 2012 re-election campaign, the president vowed to renew his effort to overhaul the nation's immigration system. It has long been expected that Obama would roll out his plans shortly after his inauguration.

The president's trip to Las Vegas is designed "to redouble the administration's efforts to work with Congress to fix the broken immigration system this year," the White House said.

Ever since November's election, in which Latino voters turned out in record numbers, Republicans and Democrats have expressed a desire to work on immigration reform. Obama has long supported a bill that would make many of the nation's 11 million undocumented immigrants without criminal records eligible to apply for an earned pathway to citizenship, which includes paying fines and learning English.

But the debate over a pathway to citizenship is expected to be contentious. Other flashpoints in an immigration reform push could include a guest-worker program, workplace enforcement efforts, border security, and immigration backlogs.

In a statement, the White House said that "any legislation must include a path to earned citizenship."

Ahead of his immigration push next week, Obama met today with a group of lawmakers from the Congressional Hispanic Caucus (CHC), including chairman Rubén Hinojosa (D-Texas) , Sen. Bob Menendez (D-N.J.), Democratic Caucus Chair Rep. Xavier Becerra (D-Calif.), and CHC Immigration Task Force Chair Rep. Luis Gutierrez (D-Ill.), the latter's office said. CHC members are expected to play a pivotal role in the debate.

"The president is the quarterback and he will direct the team, call the play, and be pivotal if we succeed. I am very optimistic based on conversations with Republicans in the House and Senate that we will do more than just talk about the immigration issue this year," Gutierrez said in a statement following the CHC meeting with Obama. "The president putting his full weight and attention behind getting a bill signed into law is tremendously helpful. We need the president and the American people all putting pressure on the Congress to act because nothing happens in the Capitol without people pushing from the outside."

A bipartisan group of eight senators, which includes Menendez, has also begun talks on drafting an immigration bill and will play an integral part in the process of passing a bill through Congress. Sen. Marco Rubio (R-Fla.), who has been participating in talks with others senators, has also unveiled his own outline for an immigration proposal.

The group of senators have reportedly eyed Friday as the date when they'll unveil their separate proposal, according to the Washington Post.

Greek economic crisis has cleared the air

EVEN the darkest cloud may have a silver lining. The sharp drop in air pollution that accompanied Greece's economic crisis could be a boon to the nation's health.

Mihalis Vrekoussis of the Cyprus Institute in Nicosia and colleagues used three satellites and a network of ground-based instruments to measure air pollution over Greece between 2007 and 2011. Levels of nitrogen dioxide fell over the whole country, with a particularly steep drop of 30 to 40 per cent over Athens. Nitrogen monoxide, carbon monoxide and sulphur dioxide also fell (Geophysical Research Letters, DOI: 10.1002/grl.50118).

Pollution levels have been falling since 2002, but the rate accelerated after 2008 by a factor of 3.5, says Vrekoussis. He found that the drop in pollution correlated with a decline in oil consumption, industrial activity and the size of the economy. "This suggests that the additional reported reduction in gas pollutant levels is due to the economic recession," he says.

In Athens, a combination of heavy car use and lots of sunshine have created serious health problems, so city dwellers should see real benefits. Sunlight triggers chemical reactions that make the car exhaust pollution more harmful, for instance by forming small particulates that cause respiratory diseases. "Hospital admissions for asthma should decline," says Dwayne Heard of the University of Leeds in the UK.

It's not all good news: despite the drop in pollutants, levels of ground-level ozone - another cause of respiratory disease - have risen. Ozone would normally be suppressed by nitrogen oxides, but those have declined. That will take the edge off the benefit, says Heard.

Greece isn't the only country where air pollution has dropped. Nitrogen oxide levels fell across Europe after the 2008 financial crisis (Scientific Reports, doi.org/j74). In the US, nitrogen dioxide levels fell between 2005 and 2011, with the sharpest fall at the height of the recession (Atmospheric Chemistry and Physics, doi.org/j75).

Such declines can be one-offs, or governments can help make them permanent, says Ronald Cohen of the University of California, Berkeley, who led the US study. "A time of crisis is a real opportunity to initiate change." After the 2008 financial downturn, for instance, the US and Europe committed to pollution cuts. "In 10 years, there will be an end to air pollution in the US and Europe," says Cohen. "It's an incredible success story."

Greece, however, is not seizing the current opportunity, says Vrekoussis. "Investments in clean technologies and low-carbon green strategies have been abandoned," he says. "I'm afraid that in the long run the negative effects will override the positives."

Global greenhouse gas emissions initially fell in the wake of the financial crisis, but not by much. Emerging economies like China and India continued their economic growth, so a small emissions drop in 2009 was followed by a huge rise in 2010 which continued in 2011.

Mixed reactions in India after high court delays controversial film's release

INDIA: Mixed reactions in India to the Madras High Court's decision to put on hold the release of a movie "Vishwaroopam". The latest work of Tamil actor and film-maker Kamal Haasan, has been accused by some Muslim groups of making the community look bad.

Haasan said he never intended to denigrate anyone and that the movie is being used by groups for political gain.

Tamil actor and film-maker Kamal Haasan has to wait a little longer for his latest movie to premiere in his home state of Tamil Nadu.

The Madras High Court put on hold the release of the film after protests against the film spilled onto the streets. Some Muslim groups petitioned for the movie to be banned, alleging that it depicts the community in a negative light.

Mohammed Hanifa, a coordinator for the Tamil Nadu Muslim Movements and Political Parties Confederation, said: "We cannot accept the picture. Muslims of Tamil Nadu are against the picture. We don't want the picture to be released."

Vishwaroopam will be released in the rest of the country as scheduled.

Kamal Haasan termed the ban "cultural terrorism" and said he will take legal recourse against the Tamil Nadu government.

Movie lovers said the ban is unfortunate.

Sanjay Roy, a literary festival organiser, said: "Yes, there is an element there which needs to be looked at. But there's no need to ban it. If you don't like something, don't go and watch it. If you don't like something, don't go and read it.

"I don't understand why artists are banned every time. Why is art banned? I have never seen any politician being banned."

Made with a budget of about US$17 million, the film is expected to do well at the box office. Besides producing and directing, Kamal Haasan also stars in the movie.

As India is set to celebrate the anniversary of its constitution formation, a judge will watch the movie and decide if Kamal Haasan gets to enjoy his cultural freedom, or if Muslim groups will get their way.

Te'o reveals biggest regret

STORY HIGHLIGHTS

• NEW: Te'o says he was embarrassed to discuss girlfriend upon learning she was fake


• NEW: But while admitting some were misled, he says he "didn't lie" publicly


• Te'o has his first on-camera interview since news broke of the girlfriend hoax


• "I wasn't as forthcoming about (the story), but I didn't lie," he tells Katie Couric

(CNN) -- He had wanted to help someone in need, this beautiful girl who had been through so much. And he ended up falling for her. They had much in common -- a strong faith, their Samoan heritage, common values -- and clicked, even though they'd never met face-to-face.

Their relationship ended, the first time, in September when Manti Te'o got a call from her hysterical brother telling him the woman he knew as Lennay Kekua had died, one day after leaving the hospital where she was being treated for leukemia.

Two months later, the relationship unraveled again, this time when he got another call from someone who claimed she was Lennay, very much alive.

In the weeks to follow -- until and after Deadspin broke the story January 16 that Lennay Kekua didn't exist, despite Te'o's repeated references to her and her death in interviews -- the Notre Dame star player admitted feeling embarrassed, scared and overwhelmed.

In his first on-camera interview since then, Te'o said that, publicly, he'd always been truthful.

"For people feeling that they were misled, that I'm sorry for," he told Katie Couric, on an episode of her talk show that aired Thursday. "I wasn't as forthcoming about it (as I could have been).

"But I didn't lie."

Then why, Couric asked, had he said the two met through his cousin and at a game his sophomore year, when he now says she had reached out to him on Facebook? Why had he told his father that he and Kekua had gotten together once in Hawaii?

And why hadn't he had stronger doubts before this winter? Like how, in their FaceTime chats, her screen always appeared black? Or how every in-person meeting they set up fell through, like when she was hospitalized or the time her brother had borrowed her car?

Or how odd was it that, in the months he'd gotten to know her well, a 22-year-old woman had a near-death accident then came down with cancer? And through all her struggles, why didn't he visit her once in the hospital -- even when he was in Southern California, like her, and she was in a coma?

Te'o said he understands why people might doubt their relationship, and him. But he told Couric that his feelings in the relationship -- and after the supposed death -- were authentic.

"What I went through was real. The feelings, the pain, the sorrow ... that was all real," said the standout linebacker and Heisman runner-up. "That's something I can't fake."

Te'o admits lying to father, not to others

The two, Te'o at Notre Dame and Kekua at Stanford University, first got acquainted his freshman year, after she reached out to him on Facebook, he said. Those first few years, they would converse but "it was a friend relationship," Te'o told Couric.

Their relationship began to go to another level, he explained, during his junior year. As it did, Te'o admitted to having his doubts, even reaching out to some others to confirm Kekua was real.

"That was my way of saying, 'Oh she's real, they met her, they've seen her,'" Te'o said of his conversations with friends. "This girl who was in the pictures, and this girl I was talking to must be the same."

But while they talked for hours, they never met face-to-face. Once, Kekua told Te'o she was in his home state of Hawaii, and the two planned to meet. He told Couric she had told him her brother had her car and she couldn't drive to him, but invited him to her hotel.

That meeting never panned out. Still, the next morning, Te'o admitted telling his father the two had, in fact, seen each other. Brian Te'o later mentioned in interviews how his son had met up with Kekua in Hawaii.

That conversation with his father, Te'o told Couric, was "the biggest lie."

"That's the thing I regret most," he said. "That's my way of trying to get my dad's approval of this young lady. Because I knew if he knew I didn't meet her, he would immediately just say no, (it is a) red flag that I obviously should have seen."

The relationship continued. On the talk show "Katie," tapes were played of voice mails left by the woman Te'o said he thought was Kekua. In one, she talked about starting her first session of chemotherapy. In another, she suspiciously called him out after she said another woman answered his phone. In another, she wished him good night: "I'll talk to you tomorrow. I love you so much hon. Sweet dreams."

In an off-camera interview January 18 with ESPN, Te'o said a man named Ronaiah Tuiasosopo was behind the hoax, saying Tuiasosopo had called him earlier this month to apologize. While Tuiasosopo or his father haven't talked publicly, his uncle recently defended him, saying, "It definitely takes two to tango."

Responding to reports Kekua may have been voiced by Tuiasosopo, Te'o said, "It sounded like a woman, but if (a man) somehow made that voice,... that's incredible talent to do that, especially every single day."

A near-death accident then a bout with leukemia

They planned to meet while he was in San Diego, but then she was severely injured in April after being struck by a drunk driver, Te'o said. He could have missed his flight to either Los Angeles or, eventually, Hawaii to be with her, but he didn't.

Manti Te'o denies he was part of girlfriend hoax

"It was a conversation that I didn't want to have with my parents," Te'o told Couric. "To say, 'Uh Mom, Dad, I missed my flight ... because I'm going to see Lennay in the hospital.' "

While she was in a coma at the hospital, Te'o said her relatives held a phone up to her ear and he talked. Nurses said the sound of his voice would cause her breath to quicken, and he'd hear the respirator and "the machines. It was very real."

She awoke from the coma, he said, as he was talking -- whispering his name and causing him to jump for joy, feeling he'd helped her.

"It goes back to what my parents taught me, to always be there for somebody when they need help," Te'o said.

There were more talks in the subsequent months, not just between the two but also involving Te'o's family. He said he was most hurt, most ashamed because the apparent hoax hurt not just him, but his father and mother.

"The belief in this person, the deception, wasn't only with Manti, it was our entire family," his mother, Ottilia Te'o, told Couric. "We had conversations with this person. So in our mind, we had followed the same pattern as Manti."

Te'o: 'I was just scared and I didn't know what to do'

Te'o said he was told that, on September 12, Kekua suddenly started to breathe hard, to sweat and, at 10:47 p.m., she died.

That was the same day his grandmother died. Three days later, he led the Fighting Irish to a 20-3 rout of Michigan State, saying he had been inspired to honor the two women with his play.

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

Even in death, Kekua continued to come up in interviews and elsewhere. She was part of Te'o's story.

Then came the December 6 phone call, from a woman he first thought was Kekua's sister. But then, he recalled, "She said, 'No Manti, it's Lennay.' "

"There was a long silent pause," Te'o said. "And I was angered to say the least."

Despite his renewed doubts, he kept talking -- including at the Heisman presentation on December 8, when he referred to his girlfriend losing her battle with cancer. A Twitter picture sent later that month showing the girl he thought was Kekua, holding a sign with that day's date, convinced him it was all a lie.

But he still didn't know what to do, or what to say.

"Part of me was saying if you say that she's alive, what would everybody think? What are you going to tell everybody who followed you, who you've inspired? What are you going to say?

He added: "I was scared. That's the truth. I was just scared, and I didn't know what to do."

On Christmas Day, he sat down with his parents in Hawaii.

Parents defend Te'o: 'He's not a liar, he's a kid'

This conversation led to one with Notre Dame coaches and administrators. But the school was mum until the Deadspin story came out.

That was followed by many stories as well as speculation about what happened and why. Did Te'o help concoct the hoax to promote his Heisman hopes? He said no. Did he help invent this relationship because he's gay? That, too, isn't true, he said.

It's uncertain how this scandal will affect his standing in the upcoming NFL Draft, set for April. Te'o said he's hoping for the best, though most disappointed in how he's hurt his family.

"The greatest joy in any child's life is to make your parents proud," he said. "The greatest pain is to know that they are experiencing pain because of you."

On the "Katie" show, his mother said she's proud of how her son has handled this entire situation -- saying that, in befriending who he thought was Kekua, he showed he "always puts others before himself."

His father said it's easy to spot the red flags in retrospect. But he said this ordeal hasn't rattled his faith in his son.

"He's not a liar. He's a kid," Brian Te'o said. "He's a 21-year-old kid trying to be a man."

CNN's Eliott C. McLaughlin contributed to this report.

Battery expert: "I would not fly in a Dreamliner"

(CBS News) WASHINGTON - Investigators say they still don't know what caused batteries to burn in two Boeing 787 Dreamliners, and until they figure that out and how to fix the problem, none of the planes will be allowed to fly.

More than any other plane, the Dreamliner relies on lithium ion batteries to help power its advanced electrical system. They're lighter and more powerful than older battery types, but they contain a highly flammable liquid electrolyte.

Boeing plans to carry on with Dreamliner production

Federal investigators are examining the disassembled battery from the 787 that caught fire in Boston January 7, spewing molten electrolyte.

George Blomgren worked for Eveready, a batteries and flashlights company, for 40 years. He says lithium ion batteries are bundled together for the 787, and that increases the risk.

"These fires burn at very high temperatures, so they are just very dangerous fires," he said.

The Boston fire, and the burned-out battery on a Dreamliner in Japan, is not the first time lithium ion batteries have caused problems.

In 2011, a Chevy Volt lithium ion battery was damaged in a crash test. Three weeks later, it burst into flames. Chevrolet installed a number of fixes to prevent fires.

Safety features also were added to lithium ion batteries in some cell phones and laptops after 56 million were recalled for risk of overheating and exploding.

Boeing says lithium ion batteries "best met the performance and design objectives of the 787" and "Based on everything we know at this point, we have not changed our evaluation."

Blomgren considers the safety of lithium ion batteries on planes questionable.

"From what I know about incidents, I would not fly in a Dreamliner tomorrow. I just wouldn't feel that it was appropriate or safe," Blomgren said.

Many experts believe in the promise of lithium ion batteries, including for airlines, but they just aren't sure its safety has been perfected.

It's Official: Women Will Serve in Combat

Women will soon be able to serve in combat, as things officially changed with the stroke of a pen today at the Pentagon.

At a joint news conference, Secretary of Defense Leon Panetta and Joint Chiefs of Staff Charman Gen. Martin Dempsey signed a memorandum rolling back a 1994 directive prohibiting women from doing so.

"They serve, they're wounded, and they die right next to each other," Panetta said of women and men in the military. "The time has come to recognize that reality.

"If they're willing to put their lives on the line, then we need to recognize that they deserve a chance," Panetta said, noting that he wants his own granddaughters and grandsons to have the same opportunities in their lives and careers.

The change won't be immediate, however. While Panetta announced that thousands of new positions will now be open to women, he has asked the military branches to submit plans by May on how to integrate women into combat operations. He set a January 2016 deadline for branches to implement the changes, giving military services time to seek waivers for certain jobs.

Both Panetta and Dempsey said they believe the move will strengthen the U.S. military force.

Florida Judge Puts Debra Lafave Back on Probation After Year Off Watch Video

"Ultimately, we are acting to strengthen the armed forces," Dempsey said. "We will extend opportunities to women in a way that maintains readiness, morale and unit cohesion."

Women have already served in combat in Iraq and Afghanistan, as ABC News' Martha Raddatz and Elizabeth Gorman reported in 2009: Prohibited from serving in roles "whose primary mission is to engage in direct combat on the ground," women in support roles, nonetheless, served in support roles on the frontlines, where they have fought, been wounded and died.

Women have also flown combat missions since 1993 and have served on submarines since 2010.

Panetta noted that 152 women have died serving in the U.S. military in Iraq and Afghanistan. Dempsey said he realized a change was inevitable when he noticed two female turret gunners protecting a senior military officer.

"It's clear to all of us that women are contributing in unprecedented ways to the military's mission of defending the nation," Panetta said. "Women represent 15 percent of the force of over 200,000 [and] are serving in a growing number of critical roles on and off the battlefield.

"I've gone to Bethesda to visit wounded warriors, and I've gone to Arlington to bury our dead. There's no distincton."

Panetta and Dempsey said President Obama supported the move, while warning them to maintain military readiness as they considered the change.

Obama hailed the move in a written statement

"Today, by moving to open more military positions -- including ground combat units -- to women, our armed forces have taken another historic step toward harnessing the talents and skills of all our citizens," he said.
