Wall Street Week Ahead: Attention turns to financial earnings

NEW YORK (Reuters) - After over a month of watching Capitol Hill and Pennsylvania Avenue, Wall Street can get back to what it knows best: Wall Street.

The first full week of earnings season is dominated by the financial sector - big investment banks and commercial banks - just as retail investors, free from the "fiscal cliff" worries, have started to get back into the markets.

Equities have risen in the new year, rallying after the initial resolution of the fiscal cliff in Washington on January 2. The S&P 500 on Friday closed its second straight week of gains, leaving it just fractionally off a five-year closing high hit on Thursday.

An array of financial companies - including Goldman Sachs and JPMorgan Chase - will report on Wednesday. Bank of America and Citigroup will join on Thursday.

"The banks have a read on the economy, on the health of consumers, on the health of demand," said Quincy Krosby, market strategist at Prudential Financial in Newark, New Jersey.

"What we're looking for is demand. Demand from small business owners, from consumers."

EARNINGS AND ECONOMIC EXPECTATIONS

Investors were greeted with a slightly better-than-anticipated first week of earnings, but expectations were low and just a few companies reported results.

Fourth quarter earnings and revenues for S&P 500 companies are both expected to have grown by 1.9 percent in the past quarter, according to Thomson Reuters I/B/E/S.

Few large corporations have reported, with Wells Fargo the first bank out of the gate on Friday, posting a record profit. The bank, however, made fewer mortgage loans than in the third quarter and its shares were down 0.8 percent for the day.

The KBW bank index <.bkx>, a gauge of U.S. bank stocks, is up about 30 percent from a low hit in June, rising in six of the last eight months, including January.

Investors will continue to watch earnings on Friday, as General Electric will round out the week after Intel's report on Thursday.

HOUSING, INDUSTRIAL DATA ON TAP

Next week will also feature the release of a wide range of economic data.

Tuesday will see the release of retail sales numbers and the Empire State manufacturing index, followed by CPI data on Wednesday.

Investors and analysts will also focus on the housing starts numbers and the Philadelphia Federal Reserve factory activity index on Thursday. The Thomson Reuters/University of Michigan consumer sentiment numbers are due on Friday.

Jim Paulsen, chief investment officer at Wells Capital Management in Minneapolis, said he expected to see housing numbers continue to climb.

"They won't be that surprising if they're good, they'll be rather eye-catching if they're not good," he said. "The underlying drive of the markets, I think, is economic data. That's been the catalyst."

POLITICAL ANXIETY

Worries about the protracted fiscal cliff negotiations drove the markets in the weeks before the ultimate January 2 resolution, but fear of the debt ceiling fight has yet to command investors' attention to the same extent.

The agreement was likely part of the reason for a rebound in flows to stocks. U.S.-based stock mutual funds gained $7.53 billion after the cliff resolution in the week ending January 9, the most in a week since May 2001, according to Thomson Reuters' Lipper.

Markets are unlikely to move on debt ceiling news unless prominent lawmakers signal that they are taking a surprising position in the debate.

The deal in Washington to avert the cliff set up another debt battle, which will play out in coming months alongside spending debates. But this alarm has been sounded before.

"The market will turn the corner on it when the debate heats up," Prudential Financial's Krosby said.

The CBOE Volatility index <.vix> a gauge of traders' anxiety, is off more than 25 percent so far this month and it recently hit its lowest since June 2007, before the recession began.

"The market doesn't react to the same news twice. It will have to be more brutal than the fiscal cliff," Krosby said. "The market has been conditioned that, at the end, they come up with an agreement."

Armstrong to admit doping in Oprah interview

AUSTIN, Texas (AP) — Lance Armstrong will make a limited confession to doping during his televised interview with Oprah Winfrey next week, according to a person with knowledge of the situation.

Armstrong, who has long denied doping, will also offer an apology during the interview scheduled to be taped Monday at his home in Austin, according to the person who spoke on condition of anonymity because there was no authorization to speak publicly on the matter.

While not directly saying he would confess or apologize, Armstrong sent a text message to The Associated Press early Saturday that said: "I told her (Winfrey) to go wherever she wants and I'll answer the questions directly, honestly and candidly. That's all I can say."

The 41-year-old Armstrong, who vehemently denied doping for years, has not spoken publicly about the U.S. Anti-Doping Agency report last year that cast him as the leader of a sophisticated and brazen doping program on his U.S. Postal Service teams that included use of steroids, blood boosters and illegal blood transfusions.

The USADA report led to Armstrong being stripped of his seven Tour de France titles and given a lifetime ban from the sport.

Several outlets had reported that Armstrong was considering a confession. The interview will be broadcast Thursday on the Oprah Winfrey Network and oprah.com.

A confession would come at a time when Armstrong is still facing some legal troubles.

Armstrong faces a federal whistle-blower lawsuit filed by former teammate Floyd Landis accusing him of defrauding the U.S. Postal Service, but the U.S. Department of Justice has yet to announce if it will join the case. The British newspaper The Sunday Times is suing Armstrong to recover about $500,000 it paid him to settle a libel lawsuit.

A Dallas-based promotions company has threatened to sue Armstrong to recover more than $7.5 million it paid him as a bonus for winning the Tour de France.

But potential perjury charges stemming from his sworn testimony denying doping in a 2005 arbitration fight over the bonus payments have passed the statute of limitations.

Armstrong lost most of his personal sponsorship — worth tens of millions of dollars — after USADA issued its report and he left the board of the Livestrong cancer-fighting charity he founded in 1997. He is still said to be worth an estimated $100 million.

Livestrong might be one reason to issue an apology or make a confession. The charity supports cancer patients and still faces an image problem because of its association with its famous founder.

Armstrong could also be hoping a confession would allow him to return to competition in elite triathlon or running events, but World Anti-Doping Code rules state his lifetime ban cannot be reduced to less than eight years. WADA and U.S. Anti-Doping officials could agree to reduce the ban further depending on what new information Armstrong provides and his level of cooperation.

Armstrong met with USADA officials recently to explore a "pathway to redemption," according to a report by "60 Minutes Sports" aired Wednesday on Showtime.

No ‘Death Star’ for US Military, White House Says

The planet-killing Death Star may have been the ultimate weapon for the Empire in the “Star Wars” films, but it has no place in the United States military today, a White House official said Friday (Jan. 11).

The statement, an official response a petition to begin building a real-life Death Star by 2016 on the White House‘s We the People website, said President Barack Obama‘s Administration cannot support building the science fiction weapon for several down-to-Earth reasons.

“The Administration shares your desire for job creation and a strong national defense, but a Death Star isn’t on the horizon,” wrote Paul Shawcross, chief of the Science and Space Branch at the White House’s Office of Management and Budget.

The Death Star petition, posted in the November, was signed by 34,435 people and the White House has pledged to respond to any petitions that garner 25,000 signatures in 30 days.

Not the least of the hurdles for a real-life Death Star is the space construction costs, which Shawcross said has been estimated at $ 850 quadrillion (that’s $ 850,000,000,000,000,000). The White House is trying to reduce the deficit, not expand it, Shawcross wrote.

Then there’s the Death Star’s planet-destroying warship nature.

“The Administration does not support blowing up planets,” Shawcross wrote.

And of course, there’s the fact that Luke Skywalker destroyed the first Death Star with a single X-wing fighter.

“Why would we spend countless taxpayer dollars on a Death Star with a fundamental flaw that could be exploited by a one-man starship?” Shawcross explained.

While there will be no moon-size Death Star in the U.S. military’s arsenal by 2016, Saturn’s real-life moon Mimas does look eerily similar to the fictional warship. [Saturn's'Death Star' Moon Mimas (Photos)]

Last year, astronomers with the agency’s planet-hunting Kepler space telescope also announced that they found a real-life version of Tatooine, Luke’s home planet with two suns. NASA also plans to send astronauts where no one has gone before — an asteroid — by 2025, and then take aim a manned trip to Mars in the 2030s.

And Shawcross also urged the public to go outside at night and look up.

“However, look carefully (here’s how) and you’ll notice something already floating in the sky — that’s no moon, it’s a space station!” Shawcross wrote. “Yes, we already have a giant, football field-sized International Space Station in orbit around the Earth that’s helping us learn how humans can live and thrive in space for long durations.”

The International Space Station  is a $ 100 billion orbiting lab — a deal compared to the Death Star — and is currently home to a six-man crew representing the United States, Russia and Canada. Construction of the space station began in 1998 and today it is the largest manmade structure in space. It has the same living space as a five-bedroom house

The space station can appear so bright to observers on Earth that at times it rivals Venus, the brightest planet in the night sky. Two American astronauts (of NASA), three Russian cosmonauts and a Canadian astronaut currently live on the station.

And Shawcross said there are other Star Wars technologies besides the Death Star that do have a place in today’s society.

“We don’t have a Death Star, but we do have floating robot assistants on the space station, a President who knows his way around a light saber and advanced (marshmallow) cannon, and the Defense Advanced Research Projects Agency, which is supporting research on building Luke’s [robotic] arm, floating droids, and quadruped walkers,” Shawcross wrote.

“We are living in the future!” Shawcross wrote. “Enjoy it. Or better yet, help build it by pursuing a career in a science, technology, engineering or math-related field.”

The Administration and NASA have both been working to spur interest in science, math, engineering and technology among students.

“If you do pursue a career in a science, technology, engineering or math-related field, the Force will be with us!” Shawcross concluded. “Remember, the Death Star’s power to destroy a planet, or even a whole star system, is insignificant next to the power of the Force.”

Saudi execution: Brutal and illegal?

STORY HIGHLIGHTS

• Saudi authorities beheaded Rizana Nafeek, a Sri Lankan woman


• She was convicted of killing a baby of the family employing her as a housemaid


• This was despite Nafeek's claims that the baby died in a choking accident


• Becker says her fate "should spotlight the precarious existence of domestic workers"

Jo Becker is the Children's Rights Advocacy Director for Human Rights Watch and author of 'Campaigning for Justice: Human Rights Advocacy in Practice.' Follow Jo Becker on Twitter.

(CNN) -- Rizana Nafeek was a child herself -- 17 years old, according to her birth certificate -- when a four-month-old baby died in her care in Saudi Arabia. She had migrated from Sri Lanka only weeks earlier to be a domestic worker for a Saudi family.

Although Rizana said the baby died in a choking accident, Saudi courts convicted her of murder and sentenced her to death. On Wednesday, the Saudi government carried out the sentence in a gruesome fashion, by beheading Rizana.

Rizana's case was rife with problems from the beginning. A recruitment agency in Sri Lanka knew she was legally too young to migrate, but she had falsified papers to say she was 23. After the baby died, Rizana gave a confession that she said was made under duress -- she later retracted it. She had no lawyer to defend her until after she was sentenced to death and no competent interpreter during her trial. Her sentence violated international law, which prohibits the death penalty for crimes committed before age 18.

Rizana's fate should arouse international outrage. But it should also spotlight the precarious existence of other domestic workers. At least 1.5 million work in Saudi Arabia alone and more than 50 million -- mainly women and girls -- are employed worldwide according to the International Labour Organization (ILO).

Again according to the ILO, the number of domestic workers worldwide has grown by more than 50% since the mid-1990s. Many, like Rizana, seek employment in foreign countries where they may be unfamiliar with the language and legal system and have few rights.

When Rizana traveled to Saudi Arabia, for example, she may not have known that many Saudi employers confiscate domestic workers' passports and confine them inside their home, cutting them off from the outside world and sources of help.

It is unlikely that anyone ever told her about Saudi Arabia's flawed criminal justice system or that while many domestic workers find kind employers who treat them well, others are forced to work for months or even years without pay and subjected to physical or sexual abuse.

Conditions for migrant domestic workers in Saudi Arabia are among some of the worst, but domestic workers in other countries rarely enjoy the same rights as other workers. In a new report this week, the International Labour Organization says that nearly 30% of the world's domestic workers are completely excluded from national labor laws. They typically earn only 40% of the average wage of other workers. Forty-five percent aren't even entitled by law to a weekly day off.

Last year, I interviewed young girls in Morocco who worked 12 hours a day, 7 days a week for a fraction of the minimum wage. One girl began working at age 12 and told me: "I don't mind working, but to be beaten and not to have enough food, this is the hardest part."

Many governments have finally begun to recognize the risks and exploitation domestic workers face. During 2012, dozens of countries took action to strengthen protections for domestic workers. Thailand, and Singapore approved measures to give domestic workers a weekly day off, while Venezuela and the Philippines adopted broad laws for domestic workers ensuring a minimum wage, paid holidays, and limits to their working hours. Brazil is amending its constitution to state that domestic workers have all the same rights as other workers. Bahrain codified access to mediation of labor disputes.

Perhaps most significantly, eight countries acted in 2012 to ratify -- and therefore be legally bound by -- the Domestic Workers Convention, with more poised to follow suit this year. The convention is a groundbreaking treaty adopted in 2011 to guarantee domestic workers the same protections available to other workers, including weekly days off, effective complaints procedures and protection from violence.

The Convention also has specific protections for domestic workers under the age of 18 and provisions for regulating and monitoring recruitment agencies. All governments should ratify the convention.

Many reforms are needed to prevent another tragic case like that of Rizana Nafeek. The obvious one is for Saudi Arabia to stop its use of the death penalty and end its outlier status as one of only three countries worldwide to execute people for crimes committed while a child.

Labor reforms are also critically important. They may have prevented the recruitment of a 17 year old for migration abroad in the first place. And they can protect millions of other domestic workers who labor with precariously few guarantees for their safety and rights.

Notre Dame's Kelly taking Eagles, NFL interest to brink

If Brian Kelly and his camp are using an NFL flirtation as a bargaining ploy, they may be pushing it to the absolute brink.

The Notre Dame coach interviewed with the Eagles on Tuesday and has a second meeting with the team set for this weekend, according to a published report. Meanwhile, Kelly continued to confer with NFL people about what it's like to coach at that level, a league source said early Saturday.

Kelly was on vacation the past few days -- though it was not believed to be a European jaunt, as multiple outlets have reported -- and the New York Daily News reported that "the Eagles and Kelly have agreed to revisit talks when he returns this weekend."

Comcast SportsNet Chicago reported that Eagles owner Jeffrey Lurie's private jet is in Chicago, though no specific reason was given. But the NFL Network's Albert Breer may have quashed the notion of a Kelly meeting by reporting the Eagles will interview Seahawks defensive coordinator Gus Bradley on Saturday in Atlanta.

The conversations with NFL folks have been set up via Kelly's camp and began before his interview with the Eagles last week, but a league source told the Tribune they continued into the weekend. It doesn't preclude Kelly's return to Notre Dame at all, but it suggests more than a passing fancy with the idea of coaching at the next level.

There has been precious little in the way of enlightenment from South Bend, Ind., during Kelly's apparent dalliance. And all of it indeed may be a way to strong-arm Notre Dame into meeting the demands of a head coach just a few days removed from a championship game appearance -- a disastrous championship game appearance, but a shot at a title nonetheless.

Athletic director Jack Swarbrick sent word through a spokesman that he would have no comment. There are people close to Kelly who had not been updated about the situation a few days into it, and there are team members who as of Friday night who had not received any communication at all from staffers on the subject.

One person familiar with the Eagles' view of the first interview says there was "strong mutual interest" between the two parties, and the Tribune's David Haugh reported Thursday that Kelly previously had reached out to an NFL coach to see how professional jobs differ from college gigs.

None of that precludes a return to Notre Dame with a new contract and more money for Kelly and his assistants, which for most of the week seemed the most likely scenario -- and still may be -- though the reported second meeting with the Eagles is an intriguing complication.

Notre Dame begins classes on Tuesday and the Irish were believed to have a team meeting of some kind set for Monday. That seemingly would put an imperative on Kelly to make a decision and get a deal done, with either side, within 24 or 48 hours.

The Eagles, meanwhile, had more interviews set with more head coaching candidates into next week. That doesn't preempt a spate of cancellations, of course, if they found their man in Kelly.

Obama, Karzai accelerate end of U.S. combat role in Afghanistan

WASHINGTON (Reuters) - President Barack Obama and Afghan President Hamid Karzai agreed on Friday to speed up the handover of combat operations in Afghanistan to Afghan forces, raising the prospect of an accelerated U.S. withdrawal from the country and underscoring Obama's determination to wind down a long, unpopular war.

Signaling a narrowing of differences, Karzai appeared to give ground in talks at the White House on U.S. demands for immunity from prosecution for any American troops who stay in Afghanistan beyond 2014, a concession that could allow Obama to keep at least a small residual force there.

Both leaders also threw their support behind tentative Afghan reconciliation efforts with Taliban insurgents, endorsing the establishment of a Taliban political office in Qatar in hopes of bringing insurgents to inter-Afghan talks.

Outwardly, at least, the meeting appeared to be something of a success for both men, who need to show their vastly different publics they are making progress in their goals for Afghanistan. There were no signs of the friction that has frequently marked Obama's relations with Karzai.

Karzai's visit came amid stepped-up deliberations in Washington over the size and scope of the U.S. military role in Afghanistan once the NATO-led combat mission concludes at the end of 2014.

"By the end of next year, 2014, the transition will be complete," Obama said at a news conference with Karzai standing at his side. "Afghans will have full responsibility for their security, and this war will come to a responsible end."

The Obama administration has been considering a residual force of between 3,000 and 9,000 troops - far fewer than some U.S. commanders propose - to conduct counterterrorism operations and to train and assist Afghan forces.

A top Obama aide said this week that the administration does not rule out a complete withdrawal after 2014, a move that some experts say would be disastrous for the weak Afghan central government and its fledgling security apparatus.

Obama on Friday left open the possibility of that so-called "zero option" when he several times used the word "if" to suggest that a post-2014 U.S. presence was far from guaranteed.

Insisting that Afghan forces were "stepping up" faster than expected, Obama said Afghan troops would take over the lead in combat missions across the country this spring, rather than waiting until the summer as originally planned. NATO troops will then assume a "support role," he said.

"It will be a historic moment and another step toward full Afghan sovereignty," Obama said.

Obama said final decisions on this year's troop cuts and the post-2014 U.S. military role were still months away, but his comments suggested he favors a stepped-up withdrawal timetable.

There are some 66,000 U.S. troops currently in Afghanistan. Washington's NATO allies have been steadily reducing their troop numbers as well despite doubts about the ability of Afghan forces to shoulder full responsibility for security.

'WAR OF NECESSITY'

Karzai voiced satisfaction over Obama's agreement to turn over control of detention centers to Afghan authorities, a source of dispute between their countries, although the White House released no details of the accord on that subject.

Obama once called Afghanistan a "war of necessity." But he is heading into a second term looking for an orderly way out of the conflict, which was sparked by the September 11, 2001, attacks on the United States by an al Qaeda network harbored by Afghanistan's Taliban rulers.

He faces the challenge of pressing ahead with his re-election pledge to continue winding down the war while preparing the Afghan government to prevent a slide into chaos and a Taliban resurgence once most NATO forces are gone.

Former Senator Chuck Hagel, Obama's nominee to become defense secretary, is likely to favor a sizable troop reduction.

Karzai, meanwhile, is eager to show he is working to ensure Afghans regain full control of their territory after a foreign military presence of more than 11 years.

Asked whether the cost of the war in lives and money was worth it, Obama said: "We achieved our central goal ... or have come very close to achieving our central goal, which is to de-capacitate al Qaeda, to dismantle them, to make sure that they can't attack us again."

He added: "Have we achieved everything that some might have imagined us achieving in the best of scenarios? Probably not. This is a human enterprise, and you fall short of the ideal."

Obama made clear that unless the Afghan government agrees to legal immunity for U.S. troops, he would withdraw them all after 2014 - as happened in Iraq at the end of 2011.

Karzai, who criticized NATO over civilian deaths, said that with Obama's agreement to transfer detention centers and the planned withdrawal of U.S. forces from Afghan villages, "I can go to the Afghan people and argue for immunity" in a bilateral security pact being negotiated.

Addressing students at Georgetown University later in the day, the Afghan leader predicted with certainty that the United States would keep a limited number of troops in Afghanistan after 2014, in part to battle al Qaeda and its affiliates.

"One of the reasons the United States will continue a limited presence in Afghanistan after 2014 in certain facilities in Afghanistan is because we have decided together to continue to fight against al Qaeda," Karzai said. "So there will be no respite in that."

Many of Obama's Republican opponents have criticized him for setting a withdrawal timetable and accuse him of undercutting the U.S. mission by reducing troop numbers too quickly.

Karzai and his U.S. partners have not always seen eye to eye, even though the American military has been crucial to preventing insurgent attempts to oust him.

In October, Karzai accused Washington of playing a double game by fighting the war in Afghan villages instead of going after insurgents who cross the border from neighboring Pakistan.

In Friday's news conference, Karzai did not back down from his previous comments that foreigners were responsible for some of the official corruption critics say is rampant in Afghanistan. But he acknowledged: "There is corruption in the Afghan government that we are fighting against."

Adding to tensions has been a rash of deadly "insider" attacks by Afghan soldiers and police against NATO-led troops training or working with them. U.S. forces have also been involved in a series of incidents that enraged Afghans, including burning Korans, which touched off days of rioting.

Wall Street slips, weighed by Wells Fargo, banks

NEW YORK (Reuters) - Stocks dipped on Friday, weighed by losses in the banking sector, after Wells Fargo & Co reported a decline in net interest margin despite a record profit in the latest quarter.

"It (Wells Fargo results) is weighing on the sector. We are keeping our fingers crossed that this won't be a sector thing and more confined to Wells Fargo, but it's definitely playing a factor today," said Larry Peruzzi, senior equity trader at Cabrera Capital Markets LLC in Boston.

Wells Fargo, the fourth-biggest U.S. bank and the nation's largest home lender, said its fourth-quarter net interest margin - a key measure of how much money banks make from loans - fell, even as profit jumped 24 percent. The bank also made fewer mortgage loans than in the third quarter.

The bank's shares were down more than 1 percent at $35.02. The S&P 500 financial sector index <.gspf> fell 0.5 percent and the KBW Banks index <.bkx> fell 0.9 percent.

Wells Fargo was the first big U.S. bank to report fourth-quarter results. Bank of America Corp , JPMorgan Chase & Co and Citigroup Inc are due to report next week.

The Dow Jones industrial average <.dji> was up 0.70 points, or 0.01 percent, at 13,471.92. The Standard & Poor's 500 Index <.spx> was down 2.56 points, or 0.17 percent, at 1,469.56. The Nasdaq Composite Index <.ixic> was down 4.49 points, or 0.14 percent, at 3,117.27.

Keenly watched Friday were also shares of Dow component Boeing , which fell 2.4 percent to $75.25 after a cracked cockpit window and an oil leak on separate flights in Japan added to other mishaps earlier in the week, compounding safety concerns about its new 787 Dreamliner. The US Department of Transportation said the jet would be subject to a review of its critical systems by regulators.

Best Buy shares rallied after its results showed a bit of a turnaround in its U.S. stores, though same-store sales were flat during the key holiday season. Shares jumped 11.4 percent to $13.60.

Basic materials shares were pressured after China's annual consumer inflation rate picked up to a seven-month high, narrowing the scope for the central bank to boost the economy by easing monetary policy. The S&P basic materials sector <.gspm> fell 0.6 percent.

Dendreon Corp shares jumped 15.3 percent to $5.89 after Sanford C. Bernstein upgraded the drugmaker's stock to "outperform" from "market-perform" and said it could be one of the best performers in 2013.

Browns introduce Rob Chudzinski as new coach

CLEVELAND (AP) — Rob Chudzinski is back for his third tour with the Cleveland Browns, and this time he's calling the shots.

Chudzinski, who spent the past two seasons as Carolina's offensive coordinator, was introduced as the club's sixth fulltime coach on Friday. He'll inherit a young roster he'll try to develop into a contender with the Browns, who have lost at least 11 games in each of the past five seasons.

The 44-year-old previously worked as an assistant with the Browns, most recently as offensive coordinator in 2008. Chudzinski has no previous head coaching experience, but he's familiar with the Browns and their history. He rooted for the Browns while growing up in Toledo, Ohio.

"I would not miss the chance for the world." Chudzinski said. "We're going to win here."

Origin of Life: Did a Simple Pump Drive Process?

A new theory proposes the primordial life-forms that gave rise to all life on Earth left deep-sea vents because of their “invention” of a tiny pump. These primitive cellular pumps would have powered life-giving chemical reactions.

The idea, detailed Dec. 20 in the journal Cell, could help explain two mysteries of life’s early origin: How did the earliest proto-cells power chemical reactions to make the organic building blocks of life; and how did they leave hydrothermal vents to colonize early Earth’s oceans?

Authors of the new theory argue the environmental conditions in porous hydrothermal vents — where heated, mineral-laden seawater spews from cracks in the ocean crust — created a gradient in positively charged protons that served as a “battery” to fuel the creation of organic molecules and proto-cells.

Later, primitive cellular pumps gradually evolved the ability to use a different type of gradient — the difference in sodium particles inside and outside the cell — as a battery to power the construction of complex molecules like proteins. And, voilà, the proto-cells could leave the deep-sea hydrothermal vents. [Image Gallery: Unique Life at Deep-Sea Vents]

“A coupling of proton gradients and sodium gradients may have played a major role in the origin of life. This is really cool, novel stuff,” Jan Amend, a researcher at the University of Southern California, who was not involved in the study, wrote in an email to LiveScience. The study reflects the increasingly popular idea that a simple, everyday source of power, not a rare occurrence like a lightning strike, could have provided the power to initially create life, he said.

Deep-sea start

Many scientists think life got its start around 3.7 billion years ago in deep-sea hydrothermal vents. But figuring out just how complex, carbon-based life formed in that primordial stew has been tricky.

Somehow, the precursors of life harnessed carbon dioxide and hydrogen available in those primitive conditions to create the building blocks of life, such as amino acids and nucleotides (building blocks of DNA). But those chemical reactions require a power source, said study co-author Nick Lane, a researcher at the University College London.

Now, Lane and William Martin, of the Institute of Molecular Evolution at the Heinrich Heine University in Germany, propose that the rocky mineral walls in ocean-floor vents could have provided the means.

The theory goes: At the time of life’s origin, the early ocean was acidic and filled with positively charged protons, while the deep-sea vents spewed out bitter alkaline fluid, which is rich in negatively charged hydroxide ions, Lane told LiveScience.

The vents created furrowed rocky, iron- and sulfur-rich walls full of tiny pores that separated the warm alkaline vent fluid from the cooler, acidic seawater. The interface between the two created a natural charge gradient.

“It’s a little bit like a battery,” Lane told LiveScience.

That battery then powered the chemical transformation of carbon dioxide and hydrogen into simple carbon-based molecules such as amino acids or proteins. Eventually that gradient drove the creation of cellular membranes, complicated proteins and ribonucleic acid (RNA), a molecule similar to DNA.

Leaving the vents

At that point, primitive cells used the thin, serpentine walls of the vent to corral the new carbon-based molecules together into precursors of cells and used the charge gradient in the environment to power the building of more complex organic chemicals.

But in order to leave the vent, primitive cells would have needed some way to carry a power-producing gradient with them — think battery pack. To solve that problem, the team looked at existing archaea bacteria in deep-sea vents.

Those primeval life-forms use a simple type of cellular pump that pushes sodium out of the cell while pulling positively charged protons in. The team proposed that a precursor to that cellular pump evolved in the membranes of the proto-cells.

The membrane started out very leaky, but over time, the membranes would have slowly closed, preventing much larger sodium particles from leaving the cell while smaller protons could still slip through. That enabled the proto-cells to still use the existing power-source in the environment — the charge gradient — while gradually evolving an independent way of getting power.

Eventually, when the pores closed completely, the primitive cells would have had a sodium pump that could power their cellular reactions, enabling more complex life to form. They could then leave their birthplace.

Testing the idea, however, will be tricky, Amend told LiveScience. “Mimicking natural conditions in the lab is a lot more difficult than it sounds.”

Why global labor reforms are vital

STORY HIGHLIGHTS

• Saudi authorities beheaded Rizana Nafeek, a Sri Lankan woman


• She was convicted of killing a baby of the family employing her as a housemaid


• This was despite Nafeek's claims that the baby died in a choking accident


• Becker says her fate "should spotlight the precarious existence of domestic workers"

(CNN) -- Rizana Nafeek was a child herself -- 17 years old, according to her birth certificate -- when a four-month-old baby died in her care in Saudi Arabia. She had migrated from Sri Lanka only weeks earlier to be a domestic worker for a Saudi family.

Although Rizana said the baby died in a choking accident, Saudi courts convicted her of murder and sentenced her to death. On Wednesday, the Saudi government carried out the sentence in a gruesome fashion, by beheading Rizana.

Rizana's case was rife with problems from the beginning. A recruitment agency in Sri Lanka knew she was legally too young to migrate, but she had falsified papers to say she was 23. After the baby died, Rizana gave a confession that she said was made under duress -- she later retracted it. She had no lawyer to defend her until after she was sentenced to death and no competent interpreter during her trial. Her sentence violated international law, which prohibits the death penalty for crimes committed before age 18.

Rizana's fate should arouse international outrage. But it should also spotlight the precarious existence of other domestic workers. At least 1.5 million work in Saudi Arabia alone and more than 50 million -- mainly women and girls -- are employed worldwide according to the International Labour Organization (ILO).

Again according to the ILO, the number of domestic workers worldwide has grown by more than 50% since the mid-1990s. Many, like Rizana, seek employment in foreign countries where they may be unfamiliar with the language and legal system and have few rights.

When Rizana traveled to Saudi Arabia, for example, she may not have known that many Saudi employers confiscate domestic workers' passports and confine them inside their home, cutting them off from the outside world and sources of help.

It is unlikely that anyone ever told her about Saudi Arabia's flawed criminal justice system or that while many domestic workers find kind employers who treat them well, others are forced to work for months or even years without pay and subjected to physical or sexual abuse.

Conditions for migrant domestic workers in Saudi Arabia are among some of the worst, but domestic workers in other countries rarely enjoy the same rights as other workers. In a new report this week, the International Labour Organization says that nearly 30% of the world's domestic workers are completely excluded from national labor laws. They typically earn only 40% of the average wage of other workers. Forty-five percent aren't even entitled by law to a weekly day off.

Last year, I interviewed young girls in Morocco who worked 12 hours a day, 7 days a week for a fraction of the minimum wage. One girl began working at age 12 and told me: "I don't mind working, but to be beaten and not to have enough food, this is the hardest part."

Many governments have finally begun to recognize the risks and exploitation domestic workers face. During 2012, dozens of countries took action to strengthen protections for domestic workers. Thailand, and Singapore approved measures to give domestic workers a weekly day off, while Venezuela and the Philippines adopted broad laws for domestic workers ensuring a minimum wage, paid holidays, and limits to their working hours. Brazil is amending its constitution to state that domestic workers have all the same rights as other workers. Bahrain codified access to mediation of labor disputes.

Perhaps most significantly, eight countries acted in 2012 to ratify -- and therefore be legally bound by -- the Domestic Workers Convention, with more poised to follow suit this year. The convention is a groundbreaking treaty adopted in 2011 to guarantee domestic workers the same protections available to other workers, including weekly days off, effective complaints procedures and protection from violence.

The Convention also has specific protections for domestic workers under the age of 18 and provisions for regulating and monitoring recruitment agencies. All governments should ratify the convention.

Many reforms are needed to prevent another tragic case like that of Rizana Nafeek. The obvious one is for Saudi Arabia to stop its use of the death penalty and end its outlier status as one of only three countries worldwide to execute people for crimes committed while a child.

Labor reforms are also critically important. They may have prevented the recruitment of a 17 year old for migration abroad in the first place. And they can protect millions of other domestic workers who labor with precariously few guarantees for their safety and rights.
