Have Astronomers Found Chemical Precursor to Life?

LONG BEACH, Calif. — Astronomers have found tentative traces of a precursor chemical to the building blocks of life near a star-forming region about 1,000 light-years from Earth.

The signal from the molecule, hydroxylamine, which is made up of atoms of nitrogen, hydrogen and oxygen, still needs to be verified. But, if confirmed, it would mean scientists had found a chemical that could potentially seed life on other worlds, and may have played a role in life’s origin on our home planet about 3.6 billion years ago.

The findings were presented Jan. 9 at the 221st annual meeting of the American Astronomical Society .

“It’s very exciting,” said Stefanie Milam, an astrochemist at NASA Goddard Space Flight Center in Greenbelt, Md., who was not involved in the study. If the findings can be verified, “this will be the first detection of this new molecule. It gives us a lot of hope for prebiotic chemistry in this particular region.”

Some astronomers think that the ingredients for life are formed in cold, gas-, dust- and plasma-filled interstellar clouds. Comets, asteroids and meteors forming in these clouds bear such chemicals, and as they continually bombard planets, they could have deposited the chemicals on Earth or other worlds, said Anthony Remijan, an astrochemist at the National Radio Astronomy Observatory in Charlottesville, Va., who led the research effort. [7 Theories on the Origin of Life]

So while life may have emerged from hydrothermal vents on Earth — a theory that many scientists support — the molecules that eventually transformed into the earliest life forms had to come from somewhere, and that “somewhere” may have been space.

To test this theory, astronomers look for the chemical fingerprints of simple, inorganic compounds forming in interstellar clouds. These compounds aren’t life or even carbon-based, but they can react with other molecules to form some of the building blocks of life, such as amino acids or the nucleotides that make up DNA. In recent years, scientists have found several different prebiotic molecules in space, said Brett McGuire, doctoral candidate in chemistry and chemical engineering at the California Institute of Technology.

In the hunt for these molecules, Remijan and colleagues scanned a star-forming region of the Milky Way called L1157-B1 using the Combined Array for Research in Millimeter-wave Astronomy (CARMA).

They found a very weak signal of hydroxylamine, which makes sense since, inside L1157-B1, a violent gas jet is slamming into the interstellar medium; the shock from this gas outflow would be sufficient force to trigger these chemical reactions in the otherwise frigid depths of an interstellar cloud. The result: hydroxylamine. In turn, hydroxylamine could react with other compounds, such as acetic acid, to form amino acids that could be dumped onto other worlds during space-rock collisions.

“We have some very preliminary evidence of its detection, a very weak signal that kind of looks like a line,” McGuire told LiveScience.

The signal is extremely faint and doesn’t definitively confirm the presence of hydroxylamine. But the signal does seem to come from the right region, McGuire said. The findings are exciting, but they are not yet a definitive chemical signature of hydroxylamine, Milam told LiveScience. “Every molecule has a fingerprint, and basically what he’s presented is the thumb print. So we need all the other fingers to confirm that this is the actual molecule.”

To confirm the finding, Remijan’s team will keep probing the star-forming region for more signals that could confirm what they’re seeing isn’t coming from some other chemicals, Milam said.

Abandoning Afghanistan a bad idea

U.S. Marines from the 3rd Battalion 8th Marines Regiment start their patrol in Helmand Province on June 27.

STORY HIGHLIGHTS

• White House aide suggested all U.S. troops could be withdrawn from Afghanistan


• Peter Bergen said the idea would be dangerous and send the wrong message


• He says U.S. has abandoned Afghanistan before and saw the rise of the Taliban


• Bergen: U.S. is seeking agreement that military will have immunity from prosecution

Editor's note: Peter Bergen is CNN's national security analyst and the author of "Manhunt: The Ten-Year Search for bin Laden, from 9/11 to Abbottabad."

(CNN) -- Afghan President Hamid Karzai will meet with President Barack Obama on Friday to discuss the post-2014 American presence in Afghanistan.

The U.S. military has already given Obama options under which as few as 6,000 or as many as 20,000 soldiers would remain in Afghanistan after 2014. Those forces would work as advisers to the Afghan army and mount special operations raids against the Taliban and al Qaeda.

Peter Bergen

But on Tuesday, Ben Rhodes, the White House's deputy national security adviser, told reporters that the Obama administration is mulling the idea of removing all U.S. troops from Afghanistan after the NATO combat mission finishes at the end of 2014.

This may be a negotiating ploy by the Obama administration as it gets down to some hard bargaining with Karzai, who has long criticized many aspects of the U.S. military presence and who is likely to be reluctant to accede to a key American demand: That any U.S. soldiers who remain in Afghanistan after 2014 retain immunity from prosecution in the dysfunctional Afghan court system. It was this issue that led the U.S. to pull all its troops out of Iraq in December, 2011 after failing to negotiate an agreement with the Nuri al-Maliki government.

Or this may represent the real views of those in the Obama administration who have long called for a much-reduced U.S. presence in Afghanistan, and it is also in keeping with the emerging Obama doctrine of attacking al Qaeda and its allies with drones but no American boots on the ground. And it certainly aligns with the view of most Americans, only around a quarter of whom now support the war in Afghanistan, according to a poll taken in September.

Security Clearance: Afghanistan options emerge

In any case, zeroing out U.S. troop levels in the post-2014 Afghanistan is a bad idea on its face -- and even raising this concept publicly is maladroit strategic messaging to Afghanistan and the region writ large.

Why so? Afghans well remember something that most Americans have forgotten.

After the Soviet Union withdrew from Afghanistan, something that was accomplished at the cost of more than a million Afghan lives and billions of dollars of U.S. aid, the United States closed its embassy in Afghanistan in 1989 during the George H. W. Bush administration and then zeroed out aid to one of the poorest countries in the world under the Clinton administration. It essentially turned its back on Afghans once they had served their purpose of dealing a deathblow to the Soviets.

As a result, the United States had virtually no understanding of the subsequent vacuum in Afghanistan into which eventually stepped the Taliban, who rose to power in the mid-1990s. The Taliban granted shelter to Osama bin Laden and his al Qaeda organization from 1996 onward.

After the overthrow of the Taliban, a form of this mistake was made again by the George W. Bush administration, which had an ideological disdain for nation building and was distracted by the Iraq War, so that in the first years after the fall of the Taliban, only a few thousand U.S. soldiers were stationed in Afghanistan.

The relatively small number of American boots on the ground in Afghanistan helped to create a vacuum of security in the country, which the Taliban would deftly exploit, so that by 2007, they once again posed a significant military threat in Afghanistan.

In 2009, Obama ordered a surge of 30,000 troops into Afghanistan to blunt the Taliban's gathering momentum, which it has certainly accomplished.

Read more: Inside the Taliban

But when Obama announced the new troops of the Afghan surge, most media accounts of the speech seized on the fact that the president also said that some of those troops would be coming home in July 2011.

This had the unintended effect of signaling to the Taliban that the U.S. was pulling out of Afghanistan reasonably soon and fit into the longstanding narrative that many Afghans have that the U.S. will abandon them again.

Similarly, the current public discussion of zero U.S. troop presence in Afghanistan after 2014 will encourage those hardliner elements of the Taliban who have no interest in a negotiated settlement and believe they can simply wait the Americans out.

It also discourages the many millions of Afghans who see a longtime U.S. presence as the best guarantor that the Taliban won't come back in any meaningful way and also an important element in dissuading powerful neighbors such as Pakistan from interference in Afghanistan's internal affairs.

Read related: Afghanistan vet finds a new way to serve

Instead of publicly discussing the zero option on troops in Afghanistan after 2014, a much smarter American messaging strategy for the country and the region would be to emphasize that the Strategic Partnership Agreement that the United States has already negotiated with Afghanistan last year guarantees that the U.S. will have some form of partnership with the Afghans until 2024.

In this messaging strategy, the point should be made that the exact size of the American troop presence after 2014 is less important than the fact that U.S. soldiers will stay in the country for many years, with Afghan consent, as a guarantor of Afghanistan's stability.

The United States continues to station thousands of troops in South Korea more than five decades after the end of the Korean War. Under this American security umbrella, South Korea has gone from being one of the poorest countries in the world to one of the richest.

It is this kind of model that most Afghans want and the U.S. needs to provide so Afghanistan doesn't revert to the kind of chaos that beset it in the mid-1990s and from which the Taliban first emerged.

Winter weather returning to Chicagoland today

Friday evening 7 day forecast

Staff report

11:43 a.m. CST, January 12, 2013

After a few days of warmth, winter returns to Chicago today, with temperatures dropping to more seasonal levels and a snowstorm scheduled to hit overnight.

Temperatures were in the 50s at O'Hare International Airport early this morning, but they'd dropped to the low 40s by late morning. ChicagoWeatherCenter.com predicts a low in the mid-20s by the end of the day.

As the temperatures drop, precipitation begins to arrive. The National Weather Service says that the wet weather – snow, sleet and freezing rain – will start to arrive between 7 and 11 p.m. tonight and will continue into Sunday. The early prediction is for 1-2 inches of snow by the time the storm passes, with hazardous travel an expected byproduct.

Sunday looks even more wintry, according to the Chicago Weather Center, with temperatures dropping into the middle teens.

Russia rejects Assad exit as precondition for Syria deal

MOSCOW/BEIRUT (Reuters) - Russia voiced support on Saturday for international peace envoy Lakhdar Brahimi but insisted Syrian President Bashar al-Assad's exit cannot be a precondition for a deal to end the country's conflict.

Some 60,000 Syrians have been killed during the 21-month-old revolt and world powers are divided over how to stop the escalating bloodshed. Government aircraft bombed outer districts of Damascus on Saturday after being grounded for a week by stormy weather, opposition activists in the capital said.

A Russian Foreign Ministry statement following talks on Friday with the United States and Brahimi reiterated calls for an end to violence in Syria, but there was no sign of a breakthrough.

Brahimi said the issue of Assad, whom the United States, European powers and Gulf-led Arab states insist must step down to end the civil war, appeared to be a sticking point at the meeting in Geneva.

Russia's Foreign Ministry said: "As before, we firmly uphold the thesis that questions about Syria's future must be decided by the Syrians themselves, without interference from outside or the imposition of prepared recipes for development."

Russia has been Assad's most powerful international backer, joining with China to block three Western- and Arab-backed U.N. Security Council resolutions aimed to pressure him or push him from power. Assad can also rely on regional powerhouse Iran.

In Geneva, Russia called for "a political transition process" based on an agreement by foreign powers last June.

Brahimi, who is trying to build on the agreement reached in Geneva on June 30, has met three times with senior Russian and U.S. diplomats since early December and met Assad in Damascus.

Russia and the United States disagreed over what the June agreement meant for Assad, with Washington saying it sent a clear signal he must go and Russia contending it did not.

CONFLICT INTENSIFIES

Moscow has been reluctant to endorse the "Arab Spring" popular revolts of the last two years, saying they have increased instability in the Middle East and created a risk of radical Islamists seizing power.

Although Russia sells arms to Syria and rents one of its naval bases, the economic benefit of its support for Assad is minimal. Analysts say President Vladimir Putin wants to prevent the United States from using military force or support from the U.N. Security Council to bring down governments it opposes.

However, as rebels gain ground in the war, Russia has given indications it is preparing for Assad's possible exit, while continuing to insist he must not be forced out by foreign powers.

Opposition activists say a military escalation and the hardship of winter have accelerated the death toll.

Rebel forces have acquired more powerful anti-tank and anti-aircraft weapons during attacks on Assad's military bases.

President Assad's forces have employed increasing amounts of military hardware including Scud-type ballistic missiles in the past two months. New York-based Human Rights Watch said they had also used incendiary cluster bombs that are banned by most nations.

STALEMATE IN CITIES

The week-long respite from aerial strikes has been marred by snow and thunderstorms that affected millions displaced by the conflict, which has now reached every region of Syria.

On Saturday, the skies were clear and jets and helicopters fired missiles and dropped bombs on a line of towns to the east of Damascus where rebels have pushed out Assad's ground forces, the Syrian Observatory for Human Rights said.

The British-based group, which is linked to the opposition, said it had no immediate information on casualties from the strikes on districts including Maleiha and farmland areas.

Rebels control large swathes of rural land around Syria but are stuck in a stalemate with Assad's forces in cities, where the army has reinforced positions.

State TV said government forces had repelled an attack by terrorists - a term it uses for the armed opposition - on Aleppo's international airport, now used as a helicopter base.

Reuters cannot independently confirm reports due to severe reporting restrictions imposed by the Syrian authorities and security constraints.

On Friday, rebels seized control of one of Syria's largest helicopter bases, Taftanaz in Idlib province, their first capture of a military airfield.

Eight-six people were killed on Friday, including 30 civilians, the Observatory said.

Wall Street falls, pressured by Wells Fargo, banks

NEW YORK (Reuters) - Stocks edged lower on Friday after Wells Fargo & Co , the first major bank to kick off fourth-quarter earnings season for the financial sector, reported a decline in net interest margin despite a record profit in the latest quarter.

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.

"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.

The bank's shares fell 1.4 percent to $34.92. The S&P 500 financial sector index <.gspf> fell 0.6 percent and the KBW Banks index <.bkx> fell 1 percent. Bank of America Corp , JPMorgan Chase & Co and Citigroup Inc are due to report results next week.

Overall earnings were expected to grow by 1.9 percent in this earnings season, according to Thomson Reuters data.

The Dow Jones industrial average <.dji> was up 6.12 points, or 0.05 percent, at 13,477.34. The Standard & Poor's 500 Index <.spx> was down 2.37 points, or 0.16 percent, at 1,469.75. The Nasdaq Composite Index <.ixic> was down 2.19 points, or 0.07 percent, at 3,119.56.

Also keenly watched Friday were shares of Dow component Boeing , which fell 2.6 percent to $75.11 after a cracked cockpit window and an oil leak on separate flights in Japan compounded safety concerns about its new 787 Dreamliner. The U.S. 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 12 percent to $13.69.

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 14.7 percent to $5.85 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.

Eager Chudzinski takes over new-look Browns

CLEVELAND (AP) — The Browns have always been a part of Rob Chudzinski's life. Now, he's the man in charge.

Chudzinski, who spent the past two seasons as Carolina's offensive coordinator, was introduced as the club's sixth fulltime coach on Friday, a once-in-a-lifetime opportunity for the 44-year-old who as a kid pretended he played tight end for the Browns during games in his backyard in Toledo, Ohio.

"It is a dream come true," Chudzinski said. "I can't wait to get started."

Chudzinski will 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 and made the playoffs only once since 1999.

Chudzinski previously worked as an assistant with the Browns, most recently as their offensive coordinator in 2008. Although he has no previous head coaching experience, owner Jimmy Haslam and CEO Joe Banner are confident they hired the best possible candidate available to turn their club into a consistent winner.

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

The Browns hauled their search to find the 14th coach in franchise history to Arizona and back. They talked to high-profile college coaches, NFL assistants and a fired pro coach who took a team to a Super Bowl.

None of them was hired.

Instead, Chudzinski became their pick.

"I believe we came back with the best coach for the Cleveland Browns," said Haslam, who flew to Charlotte, N.C. on Thursday night with Banner to offer Chudzinski the job. "He is one of the brightest young coaches in the business."

Chudzinski's first move will be to hire his staff. He will immediately meet with the assistants currently working for the Browns. Chudzinski would not comment on any possible candidates to become his coordinators. There are reports he is considering former San Diego coach Norv Turner to run his offense. Chudzinski worked for Turner with the Chargers.

"I have a plan in place," he said. "We're going to get a great staff. We have a young group of players. This is going to be about the process. Lots of people are worried about the end result, but this is going to be the right process to get us where we want to be."

Now that they've hired their coach, Haslam and Banner will focus on finding a new general manager to help pick players for Chudzinski, who will be involved in finding the GM.

The new coach — "Chud," as he's known to players and friends — worked with the Browns' tight ends in 2004 and was their offensive coordinator in 2007, when the team won 10 games — their most since an expansion rebirth in 1999. He was released when Romeo Crennel was fired in 2008.

Chudzinski said when he walked off the field after the final game that season he knew he would be coming back to Cleveland "someday, somehow."

Chudzinski replaces Pat Shurmur, another first-time coach when he was hired, who was fired on Dec. 31 after a 5-11 season. For the past two years, Chudzinski has worked with talented Panthers quarterback Cam Newton and resuscitated Carolina's offense, which was one of the league's worst before he arrived.

When Haslam and Banner embarked on their coaching search as 2013 began, the pair vowed they would wait as long as necessary to find "the right coach" for Cleveland. They promised to give their new coach final say over the roster and planned to pair him with an executive to help pick players.

Chudzinski wasn't seen by many as an option.

And then he became the choice.

Haslam said Chudzinski's passion for the Browns was a bonus, but he had all the credentials and characteristics they were looking for in a new coach.

"If Rob was from Plano, Texas, we would have hired him," Haslam said.

Chudzinski said he wants a team that attacks on both sides of the ball. He would not comment on any of Cleveland's players, and sidestepped a question about rookie Brandon Weeden, who had an uneven first season with the Browns.

Chudzinski interviewed with the team on Wednesday, when the club also visited with Cincinnati defensive coordinator Mike Zimmer. Chudzinski appeared to be a long shot for the job, not because he wasn't qualified, but because it was thought Haslam wanted to make a big splash with his first coaching hire.

However, Chudzinski wowed Haslam and Banner during his meeting and the team decided it was time to end its search in its second week. Haslam said 10 minutes into the interview that he nodded at Banner that they had found their man.

In his first season in Carolina, Chudzinski turned Newton, the No. 1 overall draft pick, loose and the Panthers set club records for total yards (6,237) and first downs (345). Carolina also scored 48 touchdowns after getting just 17 in the season before Chudzinski arrived. The Panthers jumped from last in the league in total yardage to seventh, the biggest improvement since 1999.

Haslam pointed out the Panthers scored 88 touchdowns the past two seasons. Cleveland scored 44.

Following last season, Chudzinski interviewed for head coaching jobs with St. Louis, Jacksonville and Tampa Bay before returning to Carolina.

In getting the Browns' job, Chudzinski was picked over Zimmer, Montreal Alouettes coach Marc Trestman, fired Arizona coach Ken Whisenhunt and Cardinals defensive coordinator Ray Horton. Whisenhunt was in Cleveland for a second interview on Thursday, and appeared to be the front-runner. The Browns also were expected to interview Indianapolis offensive coordinator Bruce Arians.

Chudzinski's hiring may have shocked some Cleveland fans, many of whom at fantasies about Nick Saban or Jon Gruden or Kelly brining his supersonic offense to the NFL.

But his selection is in keeping with at least one of Banner's past moves. When he was in Philadelphia's front office, Banner went outside the box and hired Green Bay assistant Andy Reid, a relative unknown who spent 14 seasons with the Eagles.

High Schoolers Control Satellites Aboard Space Station

Would you trust a 16-year-old in space? NASA evidently does. Just after the sun rose on the East Coast today (Jan. 11), astronauts aboard the International Space Station ran computer instructions, written by high school students, in bowling ball-size satellites floating inside the ISS cabin. The students’ code told the satellites exactly where to go to complete challenges such as spitting out dust clouds and avoiding obstacles. 

Ceding control of small satellites to students is part of an annual competition called the Zero Robotics SPHERES Challenge, which is hosted by NASA, the U.S. Defense Advanced Research Projects Agency and the Massachusetts Institute of Technology. Today’s run is the Zero Robotics finals. Those interested can watch a live broadcast of the event. Fifteen teams from the United States and Europe are competing to get their satellites to perform tasks related to cleaning up space junk. 

“SPHERES” stands for Synchronized Position Hold, Engage, Reorient, Experimental Satellites. MIT, NASA and DARPA researchers use SPHERES to test spacecraft maneuvers, such as docking and flying in formation. 

This year the students had to program their SPHERES to deploy dust clouds that could remove space junk from orbit, dock with another satellite to harvest its parts, and maneuver through an unknown field full of debris. The SPHERES had to perform all of those tasks autonomously, just as spacecraft would, once an ISS astronaut activated their code.

In the U.S., participating students watched their code at work over a direct transmission from the International Space Station, shown at the MIT campus. The European students watched from the European Space Research and Technology Center in the Netherlands.

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.

Jo Becker

Read more: Outrage over beheading of Sri Lankan woman by Saudi Arabia

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.

Read more: Convicted killer beheaded, put on display in Saudi Arabia

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.

NFL analyst: Bears hiring Trestman as head coach

Chicago Tribune sports reporter Brad Biggs discusses the rumors surrounding the Bears hiring Marc Trestman. (Posted: January 11, 2013).

By Brad Biggs, Tribune reporter

12:53 p.m. CST, January 11, 2013

Chicago Bears general manager Phil Emery has at least three interviews scheduled for this weekend but Jimmy Johnson strongly implies a choice has been made for the next head coach of the team.

According to the Fox analyst and former coach of the Dallas Cowboys and Miami Dolphins, Marc Trestman will be the next head coach of the Bears. That is what Johnson wrote early this morning on his personal Twitter account.

Trestman later Friday denied the rumor in an email to the Montreal Gazette. "I have not heard from the Bears and have responded in that manner on multiple levels,” Trestman wrote.

A Bears spokesman declined comment, saying the team would maintain the policy it adopted when the coaching search process began.

Johnson employed Trestman before as a quarterbacks coach when he was he head coach at the University of Miami.

“Looks like 2 of my guys getting NFL jobs ... Chud Cleveland and my QB coach at U Trestman to Chicago,” Johnson wrote on Twitter.

Johnson has not explained the situation any further. Trestman is currently the head coach of the Montreal Alouettes in the CFL. He last worked in the NFL in 2004 with the Dolphins. The Alouettes have won two Grey Cup titles under Trestman, who had also interviewed for the head job with the Browns that went to Carolina Panthers offensive coordinator Rob Chudzinski on Thursday night.

Emery was in Green Bay on Thursday night where he interviewed Packers offensive coordinator Tom Clements. It is believed Houston Texans offensive coordinator Rick Dennison will be interviewed today. Seattle Seahawks offensive coordinator Darrell Bevell is scheduled to be interviewed on Saturday in Atlanta. Emery is scheduled to interview Indianapolis Colts offensive coordinator Bruce Arians on Sunday.

Now, Johnson did not specify Trestman was specifically coming to the Bears as head coach. It is possible he could be considered for another role but Emery is on the road looking for the team’s next head coach, not in an effort to hire the offensive coordinator for his next coach.

PARIS/BAMAKO (Reuters) - The French air force carried out an air strike in Mali on Friday in support of government forces trying to push back Islamist rebels, French Foreign Minister Laurent Fabius said.

The raid came as France launched a military intervention in the west African state to help the government resist a push south by rebel forces.

Western powers fear the alliance of al Qaeda-linked militants that seized the northern two-thirds of Mali in April will seek to use the vast desert zone as a launchpad for international attacks.

"French forces brought their support this afternoon to Malian army units to fight against terrorist elements," French President Francois Hollande told reporters. "This operation will last as long as is necessary."

Hollande said United Nations Security Council resolutions meant France was acting in accordance with international laws.

Earlier, Hollande had made it clear that France would intervene to stop any further drive southward by Islamist rebels as Malian soldiers launched a counter-offensive to wrest back a town captured by militants this week.

Mali's government appealed for urgent military aid from France on Thursday after Islamist fighters encroached further south, seizing the town of Konna in the center of the country. The rebel advance caused panic among residents in the nearby towns of Mopti and Sevare, home to a military base and airport.

"We are faced with blatant aggression that is threatening Mali's very existence. France cannot accept this," Hollande said in a New Year speech to diplomats and journalists. "We will be ready to stop the terrorists' offensive if it continues."

The U.N. Security Council in December authorized the deployment of an African-led force supported by European states.

"The French believe that France, and Europe, face a real security threat from what is happening in the Sahel," said Jakkie Cilliers, executive director of the Institute for Security Studies in South Africa.

More than two decades worth of peaceful elections had earned the Mali a reputation as a bulwark of democracy in a part of Africa better known for turmoil - an image that unraveled in a matter of weeks after a coup last March that paved the way for the Islamist rebellion.

Mali is Africa's third largest gold producer and a major cotton grower, and home to the fabled northern desert city of Timbuktu - an ancient trading hub and UNESCO World Heritage site that hosted annual music festivals before the rebellion.

REINFORCEMENTS ARRIVE

Residents had seen Western soldiers arriving late on Thursday at an airport at Sevare, 60 km (40 miles) south of Konna.

Sevare residents also reported the arrival of military helicopters and army reinforcements, which took part in the counter-attack to retake Konna overnight on Thursday in a bid to roll back the militant's southward drive.

"Helicopters have bombarded rebel positions. The operation will continue," a senior military source in Bamako said.

A source at Sevare airport also said around a dozen war planes had arrived on Friday. A spokesman for the Nigerian air force said planes had been deployed to Mali for a reconnaissance mission, not for combat.

A spokesman one of the main groups in the Islamist rebel alliance said they remained in control of Konna.

Asked whether the rebels intended to press ahead to capture Sevare and Mopti, the Ansar Dine spokesman, Sanda Ould Boumama, said: "We will make that clear in the coming days." He said any intervention by France would be evidence of an anti-Islam bias.

The French foreign ministry stepped up its security alert on Mali and parts of neighboring Mauritania and Niger on Friday, extending its red alert - the highest level - to include Bamako. France has 8 nationals in Islamist hands in the Sahara after a string of kidnappings.

"Due to the serious deterioration in the security situation in Mali, the threat of attack or abduction is growing," the ministry said in its travel alert. "It is strongly recommended that people avoid unnecessarily exposing themselves to risks."
