RNC chief 'intrigued' by proposed electoral change

STORY HIGHLIGHTS

• NEW: A spokesman for the Virginia governor says he does not support the proposal


• GOP state legislatures consider changing how they allocate electoral votes


• The proposed changes would have hurt President Obama in last year's election


• A similar push followed the hotly contested 2000 presidential election

Washington (CNN) -- If at first you don't succeed, try to change the rules.

A proposal under consideration in Virginia's Republican-led state Legislature would change how the commonwealth allocates its 13 electoral votes in the wake of Democratic President Barack Obama's re-election last November.

Obama won the popular vote in the crucial battleground state to claim all 13 electoral votes, even though GOP challenger Mitt Romney beat him in seven of the 11 congressional districts.

Under the proposed alternative system, electoral votes would get divvied up by congressional districts won. In addition, Virginia's two other electoral votes -- one for each U.S. Senate seat -- would go to the candidate who won the most congressional districts.

If the district-based system had been in effect in Virginia last year, Romney would have gotten nine electoral votes to four for Obama.

Jindal urges GOP to stop being 'stupid'

While a subcommittee has advanced the Virginia proposal, skepticism expressed by some GOP state senators raised doubts that it would proceed any further.

Gov. Bob McDonnell, a Republican, does not support the plan, according to his spokesman.

"He believes Virginia's existing system works just fine as it is. He does not believe there is any need for a change," Tucker Martin said in statement.

However, Reince Priebus, newly re-elected chairman of the Republican National Committee, called the idea worth examining.

"I think it is a state issue, but personally I'm pretty intrigued by it," he told reportersFriday.

Opinion: Where the stupidity really lies

The state party chairman in Florida, Lenny Curry, questioned the wisdom of such a move at a time when the party is trying to broaden its support.

"It seems to me we ought to be focused on connecting with voters and bringing them into our party versus trying to change the game," Curry said.

To Sean Trende, the senior elections analyst at RealClearPolitics, the concept doesn't violate democratic principles, but he called it a bad idea.

"Close elections would likely always result in extensive recounts, we could see huge disparities between the popular and electoral vote, and the partisan motive behind it would be transparent," he wrote Friday on the group's website.

Currently, only Nebraska and Maine use a district-based plan for allocating electoral votes.

Their systems differ from the Virginia proposal by awarding the two additional electoral votes to the winner of the popular vote, rather than who won the most districts. Last year, both split their electoral votes between Obama and Romney.

Other GOP-controlled state legislatures reportedly contemplating changes to their electoral vote allocation include Pennsylvania, Ohio and Michigan.

Under the Electoral College system, each state is worth a certain number of electoral votes based on population. Winning the presidency requires a majority of the electoral vote, regardless of who wins the popular vote.

States have the power to decide how their electoral votes get allocated, the National Conference of State Legislatures noted on its website.

It cited a similar push for change after the 2000 election, when Democratic Vice President Al Gore won the national popular vote but lost the electoral vote, and therefore the decision, to Republican George W. Bush.

From 2001 to 2006, bills proposing adoption of the district system were introduced in many states, but failed to pass, according to the NCSL website. Both Maine and Nebraska adopted their district-based systems before 2000.

The issue reflects the regionalization of America's deep partisan divide, with splits in many states between populous urban areas that tend to be more liberal and larger, less populated rural areas that generally are more conservative.

In Virginia, Obama got strong support in two heavily populated northern districts close to Washington as well as a district that includes much of Richmond and Norfolk. Romney won more rural districts in the central, southern and western parts of the state.

Overall in Virginia, Obama got 51% of the total vote -- more than 1.97 million -- compared to Romney's 1.82 million for 47% of the total.

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.

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.

Shrinking proton puzzle persists in new measurement

A puzzle at the heart of the atom refuses to go away. The most precise measurement yet of the proton's radius confirms that it sometimes seems smaller than the laws of physics demand – an issue that has been hotly debated for two years.

The latest finding deepens the need for exotic physics, or some other explanation, to account for the inconsistency. "If we were in a hole before, the hole is deeper now," says Gerald Miller of the University of Washington in Seattle, who was not involved in the new measurement.

The saga of the proton radius began in 2010, when a group led by Randolf Pohl at the Max Planck Institute of Quantum Optics in Garching, Germany, determined the width of the fuzzy ball of positive charge – and found it was smaller than had been assumed.

Previous teams had inferred the proton's radius, which is impossible to measure directly, by studying how electrons and protons interact. One method uses the simplest atom, hydrogen, which consists of one electron and one proton. A quirk of quantum mechanics says that an electron in an atom can only orbit its proton at certain distances, corresponding to different energy levels. The electron can jump between levels if it absorbs or releases energy in the form of a photon of light.

Ball of charge

By measuring the energy of photons emitted by an excited hydrogen atom, physicists can figure out how far apart the energy levels are, and thus the distances of the permitted electron orbits. A theory called quantum electrodynamics then allows them to calculate how far the proton's ball of charge must extend to keep the electrons at those distances.

This method gave a charge radius for the proton that was about 0.877 femtometres, less than a trillionth of a millimetre.

Pohl and colleagues used a novel method. They created an exotic version of hydrogen that replaces the electron with a muon, a particle that has the same charge as the electron but is 200 times heavier. Its extra bulk makes it more sensitive to the proton's size, meaning radius measurements based on muons are orders of magnitude more precise.

The new method didn't just make the measurements more precise. It also changed them: the muonic hydrogen gave a radius of 0.8418 femtometres, 4 per cent less than before.

Scandalous result

That might not sound like much, but in the world of particle physics, where theory and experiment can agree to parts in a billion, it was scandalous. A lively discussion sprang up, with some physicists claiming problems with Pohl's experiments and interpretations, and others suggesting gaps in the standard model of particle physics.

Pohl and colleagues have now repeated their experiment. The measurement of the radius is now even more precise than in 2010 – and it is still 4 per cent smaller than the value from hydrogen-based experiments.

Pohl reckons that there are three likely explanations. His experiment could have errors, although the confirmation makes that less likely. Alternatively, the electron experiments could be off. "This would be the most boring possibility," says Pohl.

The third, and most exciting, possibility is that muons do not interact with protons in the same way as electrons. In other words, the proton's apparent radius changes a little bit depending on which particle it is interacting with.

If true, that might require the existence of unknown particles that alter the way the muon interacts with the proton. Those particles could, in turn, solve some of the problems with the standard model of particle physics. They could, for instance, provide a candidate for dark matter, the mysterious stuff that makes up more than 80 per cent of the mass in the universe.

Monumental idea

Miller, Pohl and Ron Gilman of Rutgers University in Piscataway, New Jersey helped organise a workshop with 50 proton experts in Trento, Italy, last October to hash out the details of the problem – and arrived at a verdict of sorts. "Because the muon experiments seem to be so solid, the most popular answers were that there's some beyond-the-standard-model physics differentiating between muon and electron, which would be very important," Gilman says.

"That would be monumental, truly," Miller says.

But Miller also has a less radical suggestion, which could reconcile all the measurements without invoking new particles. According to quantum electrodynamics, two charged particles can interact with each other by exchanging a photon – it's as if they spontaneously create a basketball and throw it between them, he says.

The equations also allow for a more complicated interaction where the particles create two balls, and juggle them. Until now this type of interaction was considered too rare to be important, but Miller reckons that the muon's greater mass could make it a better juggler. That would strengthen the proton's interaction with it and make the proton look smaller to the muon without requiring any new physics.

All these ideas will be up for review in a few years' time when new experiments, including shooting muons at protons to see how they scatter and building muonic helium atoms to measure their energy levels, are completed.

"It's quite likely that through other experiments, in two to three years we might get an end to this," Miller says. "It shouldn't take forever."

Man sails from PNG to Australian island on twig raft

SYDNEY: A Polish man was lucky to be alive on Friday after sailing from Papua New Guinea to a north Australian island on a raft made of twigs and sticks, through crocodile and shark-infested waters, during a cyclone.

The man was found washed up in mangroves on Saibai Island in the Torres Strait, a treacherous stretch of water that lies between the two countries.

What made his survival even more miraculous was that he attempted the trip in the aftermath of Cyclone Oswald, with 1.5 metre (five foot) swells and 40 knot winds, rescue authorities said.

"It's the first time I've heard of someone trying to cross the Torres Strait in a raft in the middle of a cyclone," Australian Maritime Safety Authority (AMSA) spokeswoman Jo Meehan told AFP, adding that the flimsy raft was held together with string.

"It's not something we'd recommend. Navigation in the area is challenging for normal vessels, it's quite treacherous with reefs and rocks, and he did it in high winds and high seas.

"He's very lucky to have made it."

Australian immigration authorities said they were waiting to interview the man and it was not clear whether he was carrying a passport.

"He has been transferred to Thursday Island where he has been detained," a spokesman said, adding that the man was being medically assessed before being interviewed to find out why he made the trip.

AMSA was alerted when residents of Saibai, which is part of Australia but only four kilometres from Papua New Guinea, spotted the man offshore on Thursday.

They sent a helicopter and a customs ship but failed to find him, so they called in local police who discovered the exhausted man in the mangroves.

Australian media reported said the Pole, who has not been named, set off from Sigabadura village in Papua New Guinea on Wednesday and that locals tried talking him out of the voyage.

One report, citing Australian authorities, said he had been dropped in Papua New Guinea by a yacht.

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.

"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.

"This milestone reflects the courageous and patriotic service of women through more than two centuries of American history and the indispensable role of women in today's military," Obama said.

Wallace: Wonders of nature have been solace of my life

Alfred Russel Wallace discovered natural selection independently of Charles Darwin. Through his letters, available online for the first time, he tells us of his research, expeditions and enduring fascination for nature's mysteries.

You are famously joint author, with Darwin, of the first paper describing the origin of species and natural selection, published in 1858. When did you first get the idea?
I begin [in 1847] to feel rather dissatisfied with a mere local collection – little is to be learnt by it. I sh[ould]d like to take some one family, to study thoroughly – principally with a view to the theory of the origin of species. By that means I am strongly of [the] opinion that some definite results might be arrived at.

This desire led you to Brazil to collect birds, butterflies and beetles to try to discover what drives the evolution of new species. Were there any incidents on the voyage?
On Friday the 6th of August [1852]… the Captain (who was the owner of the vessel) came into the cabin & said "I am afraid the ship's on fire. Come & see what you think of it."

Despite that harrowing experience, you next undertook an 8 year expedition to the Malay Archipelago, where you discovered the invisible boundary between the animals of Asia and the Australian region, which would later be called the Wallace Line in your honour. What fascinated you most on that trip?
The Birds have however interested me much more than the insects, they are proportionally much more numerous, and throw great light on the laws of Geographical distribution of Animals in the East… As an instance I may mention the Cockatoos, a group of birds confined to Australia & the Moluccas, but quite unknown in Java Borneo Sumatra & Malacca… Many other species illustrate the same fact.

You have been famously good-natured about sharing the discovery of natural selection with Darwin…
I also look upon it as a most fortunate circumstance that I had a short time ago commenced a correspondence with Mr. Darwin on the subject of "Varieties", since it has led to the earlier publication of a portion of his researches & has secured to him a claim to priority which an independent publication either by myself or some other party might have injuriously effected

What did you and Darwin have in common?
In early life both Darwin and myself became ardent beetle-hunters. Both Darwin and myself had, what he terms "the mere passion of collecting"… Now it is this superficial and almost child-like interest in the outward forms of living things, which, though often despised as unscientific, happened to be the only one which would lead us towards a solution of the problem of species.

Do you feel your contribution has been overlooked?
The idea came to me, as it had come to Darwin, in a sudden flash of insight: it was thought out in a few hours – was written down with such a sketch of its various applications and developments… then copied on thin letter-paper and sent off to Darwin – all within one week.

I should have had no cause for complaint if the respective shares of Darwin and myself in regard to the elucidation of nature's method of organic development had been thenceforth estimated as being, roughly, proportional to the time we had each bestowed upon it when it was thus first given to the world – that is to say, as 20 years is to one week.

You helped Darwin with the puzzle of bright colouration in animals, which led to the concept of warning colours. To ask his question again, why are some caterpillars so brightly coloured?
[Since some]… are protected by a disagreeable taste or odour, it would be a positive advantage to them never to be mistaken for any of the palatable caterpillars… Any gaudy & conspicuous colour therefore, that would plainly distinguish them from the brown & green eatable caterpillars, would enable birds to recognise them easily as a kind not fit for food, & thus they would escape seizure which is as bad as being eaten.

How did you feel looking back on your life's work, at the age of 89?
The wonders of nature have been the delight and solace of… life. Nature has afforded… an ever increasing rapture, and the attempt to solve some of her myriad problems an ever-growing sense of mystery and awe.

Do you have a message for our readers?
I sincerely wish you all some of the delight in the mere contemplation of nature's mysteries and beauties which I have enjoyed.

Resurgent inflation dampens Vietnam stimulus hopes

HANOI: Vietnam's inflation accelerated in January, according to official data, reducing expectations of further monetary stimulus to boost the economy.

Consumer prices were up by 7.07 percent this month from a year earlier, following a 6.8 rise in December, the General Statistics Office in Hanoi said in a statement. Month-on-month prices gained 1.25 percent.

A further increase in prices is expected next month due to high demand before the Lunar New Year festival which starts on February 10, one Hanoi-based banker who did not want to be named told AFP.

Vietnam repeatedly raised interest rates in 2011 to prevent the economy from overheating and to rein in double-digit inflation, but with the economy cooling the authorities last year resumed monetary stimulus efforts.

The central bank in December cut interest rates for the sixth time since March as annual economic growth slowed to the weakest pace in 13 years, at roughly five percent for 2012.

Resurgent inflation is now seen as limiting the scope for further monetary stimulus that could stoke price pressures.

"It will not be easy to keep inflation below the government's initial target of 6.9 percent" in 2013, said one independent analyst who asked not to be named.

"The authorities will have to be very careful about future monetary policy. It is too early to say if they will have to raise interest rates again. They are in the middle of nowhere and don't know which path to follow."

The communist nation's economic woes are compounded by worries over toxic debts in the banking sector, falling foreign direct investment and a string of financial scandals among state-owned firms.
